How to deploy crysatl report to server with asp.net

2009-05-01T20:57:00.000-07:00

Hi Guys,

Most of the developer has a doubt how they could deploy crystal report with asp.net on server, what are component they need to deploy?.

here full explanation about Deployment and license.

A common misconception about deploying a Crystal Reports application written in ASP.NET is that the remote server must have the Crystal Reports .NET server components installed. The only thing to keep in mind is that you must purchase a licensed copy of Crystal Reports from Business Objects (www.businessobjects.com) in order to deploy your application to a remote server. The license for the version that comes shipped with Visual Studio .NET is just for evaluation and only works on the local development machine.

The issue that developers run into is how the Crystal Reports Developer tool is installed on the development machine. When installed, the developer tool installs the server components into the following directory:

C:\Program Files\Common Files\Crystal Decisions\2.5\managed

From there, the components are registered into the local machine's Global Assembly Cache (GAC) located in C:\windows\assembly. If you are using Visual Studio .NET to develop your application, then you reference the Crystal Decisions classes from the GAC. This is fine when you run the application on the local machine. But when you deploy the application to the remote server, by default you will get an error because the Crystal Decisions components are not registered in the remote server's GAC. Here is how you work around this issue.

For all of the classes your application references, you need to go to the above Common Files directory and copy the matching DLL files to your application bin folder. The bin folder is located in the root of your Visual Studio .NET application. Once you have copied the DLLs, remove any old references from your Visual Studio .NET application. You will find this setting in Solution Explorer under References. Right-click any CrystalDecisions.* reference and select Remove. Then right-click on Reference and select Add Reference. Click Browse, where the default directory should be your application's root, and double-click the bin directory. Select the Crystal Decisions components and click Open and then OK. Recompile your application, and upload it to the remote application. Make sure you upload all of the contents of the bin folder.

With the steps above, you should not have any issues deploying your Crystal Reports application built with Visual Studio .NET. If you are still using classic ASP to generate your Crystal Reports, then the components still have to be registered on the server: either use the Installation CD or extract the components and manually register the components on the web server using regsvr32.exe or a COM+ package. You can find additional support information at www.businessobjects.com/support/default.asp.

Full Screen featues in Windows mobile.

2008-09-10T19:25:00.001-07:00

Hi Guys,

I look msdn forums last few days,in the forum many guys asked about the full screen features in windows mobile. Since i will post here my code for that.

The full screen features we can do by two ways.
1. We can do simplify in Windows mobile 5.0 or later like hide the menu,give empty text and set widows state is maximized.
2.we can do by the calling P/Invoke.
it's little interesting, because of OS API have a interesting method "SHFullScreen"

So when we pass our current form handle and window states to this method it's done.

before that we must get window handle to for current window.

so sample code below

public class WinAPI
{

internal const int SHFS_SHOWTASKBAR = 0x0001;
internal const int SHFS_HIDETASKBAR = 0x0002;
internal const int SHFS_SHOWSIPBUTTON = 0x0004;
internal const int SHFS_HIDESIPBUTTON = 0x0008;
internal const int SHFS_SHOWSTARTICON = 0x0010;
internal const int SHFS_HIDESTARTICON = 0x0020;
// Code used to hide the Windows bar

[DllImport("aygshell.dll", EntryPoint = "SHFullScreen", SetLastError = true)]
internal static extern bool SHFullScreen(IntPtr hwndRequester, int dwState);
[DllImport("coredll.dll", EntryPoint = "GetForegroundWindow", SetLastError = true)]
internal static extern IntPtr GetForegroundWindow();
[DllImport("coredll.dll")]
public static extern IntPtr GetCapture();
// Code used to hide the Windows bar
public static void FullScreen()
{
IntPtr hwnd = GetForegroundWindow();
SHFullScreen(hwnd, SHFS_HIDETASKBAR);
}
}

that's all

thank you

}

public byte[] ToByteArray()
{
byte[] aData = new byte[0x2c];
Util.SetUInt(aData, 0, 0x2c);
return aData;
}

}

then i want to get snapshot for thread collections.

if i want to get thread snapshot olny , flag should be 4.

[DllImport("toolhelp.dll", EntryPoint = "CreateToolhelp32Snapshot", SetLastError = true)]
private static extern IntPtr CreateToolhelp32SnapshotAPI(uint flags, uint processid);

[DllImport("toolhelp.dll", EntryPoint = "CloseToolhelp32Snapshot", SetLastError = true)]

private static extern int Thread32FirstAPI(IntPtr handle, byte[] te);

[DllImport("toolhelp.dll", EntryPoint = "Thread32Next", SetLastError = true)]
private static extern int Thread32NextAPI(IntPtr handle, byte[] te);

public static THREADENTRY32[] GetThreads(uint processID)
{
ArrayList list = new ArrayList();
IntPtr handle = CreateToolhelp32Snapshot(4, processID);
if (((int) handle) <= 0)
{
throw new Exception("Unable to create snapshot");
}
try
{
byte[] te = new THREADENTRY32().ToByteArray();
for (int i = Thread32First(handle, te); i == 1; i = Thread32Next(handle, te))
{
THREADENTRY32 threadentry = new THREADENTRY32(te);
if ((processID == 0) || (threadentry.th32OwnerProcessID == processID))
{
THREADENTRY32entry = new THREADENTRY32(threadentry);
list.Add(entry);
}
}
}
catch (Exception exception)
{
throw new Exception("Exception: " + exception.Message);
}
CloseToolhelp32Snapshot(handle);
return (THREADENTRY32[]) list.ToArray(typeof(THREADENTRY32));
}

That's all

try and give a feedback.

Gradient BackGround in Windows mobile

2008-07-15T21:26:00.001-07:00

Hi Guys,

Another cool stuff in this series, how make to gradient background in Windows mobile device forms?.

MSDN have answer for above question. because of .NET CF haven't support directly draw Gradient Background, but Win CE API Have support, so we can play with P/Invoke, can make a cool and pretty background.

Just Sample here

Load Image to PictureBox in Windows Mobile

2008-07-15T21:17:00.000-07:00

Hi guys,
Another cool stuff, many guys, asking in MS forums, how load the image to picture box from the device directory. it's pretty easy, there have many ways.

1.loan image directly from the location
2. load the image from the memory stream.

So here code for you

1.
pictureBox.Image = new Bitmap (“Full.Path.To.Bitmpap.”);

2.
private void LoadImage(string filePath)
{
using (FileStream reader = new FileStream(filePath, FileMode.Open))
{
byte[] data = new byte[reader.Length];
reader.Read(data, 0, (int)reader.Length);
using (MemoryStream memory = new MemoryStream(data))
{
pictureBox1.Image = new Bitmap(memory);
pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
}
}
}

Transparent Label in .NET Compact framework

2008-07-15T20:33:00.000-07:00

Hi Guys,

I seen in MS forums lof of guys, asking how to make transparent label.
it's pretty simple, when we use the Graphics object in .NET CF.

Here complete code for create transparent label.

private void DrawLabel (Label label, Graphics gfx)

{

if (label.TextAlign == ContentAlignment.TopLeft)

{

gfx.DrawString(label.Text, label.Font, new SolidBrush(label.ForeColor), label.Bounds);

}

else if (label.TextAlign == ContentAlignment.TopCenter)

{

SizeF size = gfx.MeasureString(label.Text, label.Font);

float left = ((float) this.Width + label.Left) / 2 - size.Width / 2;

RectangleF rect = new RectangleF(left, (float) label.Top, size.Width, label.Height);

gfx.DrawString(label.Text, label.Font, new SolidBrush(label.ForeColor), rect);

}

else //is aligned at TopRight

{

SizeF size = gfx.MeasureString(label.Text, label.Font);

float left = (float) label.Width - size.Width + label.Left;

RectangleF rect = new RectangleF(left, (float) label.Top, size.Width, label.Height);

gfx.DrawString(label.Text, label.Font, new SolidBrush(label.ForeColor), rect);

}

}

Use the Sync Framework with C#

2008-01-09T00:39:00.001-08:00

Hi Guys

Micro soft introduce new framework for all type sync. This framework have varity type of the specify sync operation with database or filesystem.

List of those are,

1.ADO.Net

2.Common(File System)

You can downlaod SyncFramework from bellow url

http://www.microsoft.com/downloads/details.aspx?FamilyId=35E8F16E-AAA4-4919-8B3C-1CE4EA1F6552&displaylang=en

The Sync framework have managed class libraries. So we can code with C# or other your desired language (MS).

After download and installed , create a new Project with C# or your desired language.

I had create console application with C#

Afte you must add References Microsoft Synchronization

using System;
using System.IO;
using Microsoft.Synchronization;
using Microsoft.Synchronization.Files;

public class FileSyncProviderSample

return ;
}

string replica1RootPath = args[0];

{
replicaId = new SyncId( Guid .NewGuid());
sw.WriteLine(replicaId.GetGuidId().ToString( "D" ));
}
}
}

return replicaId;
}
}

basically sync framework work GUID as references. Because of Sync is time depend operation,so we must need a unique id for identification our file/DB is changed , removed and etc.

Con

The SyncFramework had greate feature for sync operation to all types of operation.

You can use the Sync framework for Database Sync , File System Sync,And Mobile decvice File Sync.

Access Assembly file and get Product informations

2007-12-27T21:51:00.000-08:00

Hi Guys

We have good features in the .net based on the application version and customizations. Basically dot net provide unique assembly file for the common setting within the Projects. And we can play with that file within code as well. How I can say that? The dot net give few attributes based on the assembly manipulations. Let say we want to know the current version of the Product, so we want to access assembly file and get answer from that file. Since when we try access that product version attribute in the assembly file, we must use the AssemblyVersionAttribute attribute.

And lot’s customization attribute exist in the .net class library based on the assembly file.

List of commonly using attributes.

1. 1.AssemblyTitleAttribute

2. 2.AssemblyCompanyAttribute

3. 3.AssemblyVersionAttribute

4. 4.AssemblyProductAttribute

5.5 5.AssemblyCopyrightAttribute

6. 6.AssemblyDescriptionAttribute

Now see, somebody can know how use those attribute with our coding .somebody may be can’t know. This article provides simple class with commonly using attribute, and gets information from the assembly about the product.

Let’s see the class.

using System;

using System.Collections.Generic;

using System.Text;

using System.Reflection;

namespace AccessAssembly

{

public class ApplicationDetails

{

static string companyName = string.Empty;

///

/// Get the name of the system provider name from the assembly

///

public static string CompanyName

{

get

{

Assembly assembly = System.Reflection.Assembly.GetEntryAssembly();

if (assembly != null)

{

object[] customAttributes = assembly.GetCustomAttributes(typeof(AssemblyCompanyAttribute), false);

if ((customAttributes != null) && (customAttributes.Length > 0))

{

companyName = ((AssemblyCompanyAttribute)customAttributes[0]).Company;

}

if (string.IsNullOrEmpty(companyName))

{

companyName = string.Empty;

}

return companyName;

}

static string productVersion = string.Empty;

///

/// Get System version from the assembly

///

public static string ProductVersion

{

get

{

Assembly assembly = System.Reflection.Assembly.GetEntryAssembly();

if (assembly != null)

{

object[] customAttributes = assembly.GetCustomAttributes(typeof(AssemblyVersionAttribute), false);

if ((customAttributes != null) && (customAttributes.Length > 0))

{

productVersion = ((AssemblyVersionAttribute)customAttributes[0]).Version;

}

if (string.IsNullOrEmpty(productVersion))

{

productVersion = string.Empty;

}

return productVersion;

}

static string productName = string.Empty;

///

/// Get the name of the System from the assembly

///

public static string ProductName

{

get

{

Assembly assembly = System.Reflection.Assembly.GetEntryAssembly();

if (assembly != null)

{

object[] customAttributes = assembly.GetCustomAttributes(typeof(AssemblyProductAttribute), false);

if ((customAttributes != null) && (customAttributes.Length > 0))

{

productName = ((AssemblyProductAttribute)customAttributes[0]).Product;

}

if (string.IsNullOrEmpty(productName))

{

productName = string.Empty;

}

return productName;

}

static string copyRightsDetail = string.Empty;

///

/// Get the copyRights details from the assembly

///

public static string CopyRightsDetail

{

get

{

Assembly assembly = System.Reflection.Assembly.GetEntryAssembly();

if (assembly != null)

{

object[] customAttributes = assembly.GetCustomAttributes(typeof(AssemblyCopyrightAttribute), false);

if ((customAttributes != null) && (customAttributes.Length > 0))

{

copyRightsDetail = ((AssemblyCopyrightAttribute)customAttributes[0]).Copyright;

}

if (string.IsNullOrEmpty(copyRightsDetail))

{

copyRightsDetail = string.Empty;

}

return copyRightsDetail;

}

static string productTitle = string.Empty;

///

/// Get the Product tile from the assembly

///

public static string ProductTitle

{

get

{

Assembly assembly = System.Reflection.Assembly.GetEntryAssembly();

if (assembly != null)

{

object[] customAttributes = assembly.GetCustomAttributes(typeof(AssemblyTitleAttribute), false);

if ((customAttributes != null) && (customAttributes.Length > 0))

{

productTitle = ((AssemblyTitleAttribute)customAttributes[0]).Title;

}

if (string.IsNullOrEmpty(productTitle))

{

productTitle = string.Empty;

}

return productTitle;

}

static string productDescription = string.Empty;

///

/// Get the description of the product from the assembly

///

public static string ProductDescription

{

get

{

Assembly assembly = System.Reflection.Assembly.GetEntryAssembly();

if (assembly != null)

{

object[] customAttributes = assembly.GetCustomAttributes(typeof(AssemblyDescriptionAttribute), false);

if ((customAttributes != null) && (customAttributes.Length > 0))

{

productDescription = ((AssemblyDescriptionAttribute)customAttributes[0]).Description;

}

if (string.IsNullOrEmpty(productDescription))

{

productDescription = string.Empty;

}

return productDescription;

}

Let see simple explanation get product description from the assembly file

public static string ProductDescription

{

get

{

//get the entry assebly file for the product

Assembly assembly = System.Reflection.Assembly.GetEntryAssembly();

if (assembly != null)

{

//now get the customattribute for the AssemblyDescriptionAttribute

object[] customAttributes = assembly.GetCustomAttributes(typeof(AssemblyDescriptionAttribute), false);

if ((customAttributes != null) && (customAttributes.Length > 0))

{

productDescription = ((AssemblyDescriptionAttribute)customAttributes[0]).Description;

}

if (string.IsNullOrEmpty(productDescription))

{

productDescription = string.Empty;

}

return productDescription;

}

We want to get all custom attribute from the assembly file based on the AssemblyDescriptionAttribute .

object[] customAttributes = assembly.GetCustomAttributes(typeof(AssemblyDescriptionAttribute), false);

After access the first attribute in the collections, and get the value from that

productDescription = ((AssemblyDescriptionAttribute)customAttributes[0]).Description;

That’s it. and enjoy

Con

The .net provides a good customization based on the assembly file. So please try access all other attributes in the assembly file and enjoy.

CLS Attribute in DotNet

2007-12-17T21:12:00.001-08:00

Hi Guys,

The when i see the microsoft forums and other forums sites, many guys ask about CLSCompliant attribute in the class file or assembly. i have idea about that , and i will post here. It's not complicated, but have some conditions and etc...

The conditions means, CLS-Command Language Specification(.NET).When i can say .net is great framework for all guys.because of it's multi language supporting such as VB.NET,C++.NET,C#.NET,J# and etc....Somebody can ask how can support a framework to multi language? answer is that is th .NET FRAMEWORK.

Come to point..
so when we try a code in any language with .net Framework, we must follow few rules , when we will apply CLSCompliant attribute.

a::The methods are not same. it;s we have one method call "GetUsers()", and we don't have a method like "GETUSERS()".

b::Only properties and methods may be overloaded, Operators should not be overloaded.

c::We must avoid unsignned datatype within the class file

d::Publicly exposed members cannot start with an underscore ( _ )

e::Unsafe types like pointers should not be used with public members. However they can be used with private members.

f::Operators can't be overloaded

g::Unsigned types should not be part of the public interface of the class.

we can apply CLSCompliant to assemblies, modules, types, and members.

Example::A(apply to class)
[CLSCompliant(true)]
public class Smp
{

}

Example::B(apply to assembly
using System;
[assembly:CLSCompliant(true)]

Con....

If you develop applications that conform to the CLS, your program will be interoperable with a wide range of .Net supported programming languages. Therefore, your application is likely to have a wider customer base than a non-CLS-compliant version of your application. You can make sure that the C# programs you develop are CLS compliant by using the CLSCompliantAttribute, which will cause the compiler to raise errors if the program is not CLS compliant.

The New features in .Net Compact Framework 3.5

2007-11-06T06:37:00.000-08:00

The .NET Compact Framework team has spent the last year planning and developing the next version of the .NET Compact Framework 3.5, which will align with the .NET Framework 3.5 shipping in next version of Visual Studio code named “Orcas”. The team has focused its efforts in 4 areas including, addressing core problems of creating distributed mobile applications by enabling mobile devices to interoperate with Windows Communication Foundation services, Implementing device specific features from LINQ, continuing to implement highly requested features and refining NETCF’s ability to diagnose and solve reliability and supportability issues.

The first release of NETCF 3.5 went public a few weeks ago in the Orcas January CTP. This release of NETCF does not include the complete list of features but is a step toward the final feature set. New builds of NETCF will be included in each new public drop of Orcas with the majority of features being included by Orcas Beta1. Below is a list of features included in the January CTP. If you’re interested in these new features start by downloading the Orcas January CTP using either the VPC image at http://www.microsoft.com/downloads/details.aspx?FamilyId=1FF0B35D-0C4A-40B4-915A-5331E11C39E6&displaylang=en or try installing it to your test PC at http://www.microsoft.com/downloads/details.aspx?FamilyId=69055927-458B-4129-9047-FCC4FACAE96C&displaylang=en

New Features Included in the Orcas January CTP:
• System.IO.Compression support, including support for HTTP compression.
• Support for a subset of Linq’s Standard Query Operators.
• SoundPlayer support using WaveOut allowing for multiple sounds to play at once.
• New API in Microsoft.WindowsCE.Forms for easily distinguishing Smartphone and Pocket PC.
• Allow Nested FuncEval's.
• Enhanced logging for interop functionality with native code.
• Stack Trace Enhancements.
• GAC Improvements.
• Allow for StrongName keys greater than 1024 long.
• To improved logging of finalizer activities to enhance product supportability.
• Allow log files to be read at runtime.

Thanks

New features in .Net Framework 3.5

2007-11-06T06:35:00.000-08:00

Faster .NET Framework execution

1. Faster garbage collection
2. Smarter, faster NGen requiring smaller working set RAM
3. 64 bit client improvements
4. ThreadPool performance improvements
5. Security check caching during NGen

Base Class Library – New Class Additions

6. BigInteger, HashSet and DateTime2 types
7. NSA Suite ”B” and FIPs compliant cryptography
8. Lightweight Reader/Writer Lock Classes
9. Anonymous and Named Pipes IO Classes
10. Integration with Event Tracing for Windows
11. New Addin hosting model for extensibility

Language Integrated Query (LINQ)

Deep integration of LINQ data-awareness into the programming languages and framework.

Workflow Enabled Services – Process and Messaging together

Using workflow to provide for durable and long-running services. New Tools, WF activities and new programming model classes have been added to simplify building workflow-enabled services using WF and WCF. This allows a .NET Framework developer to build business logic for a service using WF and expose messaging from that service using WCF. These improvements not only provide tools for this scenario but they reduce the amount of glue code that was previously required.

Web 2.0 Friendly and AJAX Enabled WCF Services

Ajax is a web development technique for making asynchronous exchanges of small amounts of data between browser and web service calls from the browser client script to the web server. A programming model is provided for building Ajax style web applications using WCF services. An HTTP programming model is also provided allowing for REST style web services.

Visual Studio Developer Tools for WF, WCF and in Visual Studio “Orcas”

Visual Studio”Orcas” has built in tools for web service authoring with WCF and for building workflow enabled software with WF. There are new project templates for WCF services, WF business logic, workflow enabled services, and AJAX services. The templates are conveniently set up to compile and run even before any custom code is added enabling .NET developers to get going quickly. There are also numerous other tools for developing with WF, WCF and WPF.

More WS-* Standards Support

Implementation in WCF of the latest OASIS specifications Web Services Atomic Transaction (WS-AtomicTransaction) 1.1, WS-ReliableMessaging 1.1, WS-SecureCOnversation and Web Services Coordination (WS-Coordination) 1.1.

RSS and ATOM Syndication API

Applications built using WCF will be able to easily expose syndicated data which can be consumed by an RSS or ATOM reader.

Partial Trust Support for WCF Hosting

Partial trust on the vlient is provided for ASMX parity focussing mainly on partially trusted WCF applications deployed through click-once. Support is provided for basic HTTP binding provided that the application runs in the Intranet zone and have granted the apropriate WebPermission. Secure communication is possible through transport security only. All other features are not available to partially trusted applications including hosting services, duplex communications, non-HTTP transports, WS-* protocols and any WF use.

Rules Data Improvements

The rules engine in WF is improved to add support for C# 3.0 extension metods, and for operator overloading . Also the ”new” operator is added to compete the base set of expression types.

Built-in WPF tools for Visual Studio “Orcas”

The Visual Studio designer for WPF was previously released as a CTP. It is not integrated into the development environment and is significantly improved.

Additional WPF Features and Improved Performance

WPF has smoother animations, faster startup and better overall performance. There are also new data types available for data binding with LINQ. Better integration support is now provided for with codename “WPF/E”.

thanks
