Full Screen featues in Windows mobile.

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

Hi How to use the System State in Windows mobile

Hi Guys

here simple sample how to use the system state class in windows mobile.

Question: How to check the cradlepresent in the Windows mobile Device or Emulator ?

Answers:

SystemState cradleState = null;

private void Init()
{
cradleState = new SystemState(SystemProperty.CradlePresent);
cradleState.Changed += new ChangeEventHandler(cradleState_Changed);
}

void cradleState_Changed(object sender, ChangeEventArgs args)
{
bool isPresent =Convert.ToBoolean(SystemState.GetValue(SystemProperty.CradlePresent));
if (isPresent)
{
MessageBox.Show("Present");
}
}

thank you

Get List of threads in Windows MObile.

Hi Guys,

it's another nice good morning, because of when i look MS forums last night, one guy asked , how can get list of threads in .net CF. then i tried work out in my home. then it's come sounds is good.

Here code for you.

first i want to create threadentry32 structure.
class THREADENTRY32
{

public uint cntUsage;
public uint dwFlags;
public uint dwSize;
public uint th32AccessKey;
public uint th32CurrentProcessID;
public uint th32OwnerProcessID;
public uint th32ThreadID;
public int tpBasePri;
public int tpDeltaPri;
public THREADENTRY32()
{
}
public THREADENTRY32(byte[] aData)
{
this.dwSize = BitConverter.ToUInt32(aData, 0);
this.cntUsage = BitConverter.ToUInt32(aData, 4);
this.th32ThreadID =BitConverter.ToUInt32(aData, 8);
this.th32OwnerProcessID = BitConverter.ToUInt32(aData, 12);
this.tpBasePri = BitConverter.ToInt32(aData, 0x10);
this.tpDeltaPri = BitConverter.ToInt32(aData, 0x18);
this.dwFlags = BitConverter.ToUInt32(aData, 0x20);
this.th32AccessKey = BitConverter.ToUInt32(aData, 0x24);
this.th32CurrentProcessID = BitConverter.ToUInt32(aData, 40);
}

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 CloseToolhelp32SnapshotAPI(IntPtr handle);

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.

How to create Action Lable in .Net compact framework.

Hi Guys,

Now i'm back in my blog, so i have plan post some cool stuff in my blog every day.

According that, today i will post a code for , how to create Action Lable in .NETCF.

It's pretty simple, Because of we dont need play with P/Invoke. but we want to play with GDI.

Because of i want to create a graphical objects,

Here complete code for you.


using System;
using System.Windows.Forms;
using System.Drawing;

namespace RaveSoftBlog
{
///

/// Arrow label button control.
///

public class ActionLabel : Control
{
class Const
{
public static Color DisableColor = Color.FromArgb(150,150,80);
public static Color PushedColor = Color.FromArgb(160,100,0);
public static Color ForeColor = Color.FromArgb(90,90,45);
public static Color BulletColor = Color.FromArgb(180,180,110);
public const string FontName = "Arial";
public const int FontSize = 10;
public const int BulletSize = 8;
}

// internal fields
bool m_pushed;
Rectangle m_rcHitArea;
Point[] m_bulletPts;

// gdi objects
Bitmap m_bmp;
Font m_font;
Pen m_penPushed, m_penFore, m_penDisabled;
Brush m_brushPushed, m_brushFore, m_brushDisabled;

// ctor
public ActionLabelControl()
{
// colors
this.ForeColor = Const.ForeColor;

// gdi objects
CreateGdiObjects();
}

protected override void OnPaint(PaintEventArgs e)
{
// draw to memory bitmap
CreateMemoryBitmap(e.Graphics);
Graphics g = Graphics.FromImage(m_bmp);
DrawLabel(g);

// blit memory bitmap to screen
e.Graphics.DrawImage(m_bmp, 0, 0);
}

protected override void OnPaintBackground(PaintEventArgs e)
{
// don't pass to base since we paint everything, avoid flashing
}

protected override void OnEnabledChanged(EventArgs e)
{
// redraw when enabled state changes
Invalidate();
}

// draw label and arrow
private void DrawLabel(Graphics g)
{
// background
g.Clear(Parent.BackColor);

// determine what pen and brush to use
Pen pen = m_pushed ? m_penPushed :
(this.Enabled ? m_penFore : m_penDisabled);

Brush brush = m_pushed ? m_brushPushed :
(this.Enabled ? m_brushFore : m_brushDisabled);

// draw solid arrow if enabled
if (this.Enabled)
g.FillPolygon(brush, m_bulletPts);

g.DrawPolygon(pen, m_bulletPts);

// label text
Size textSize = g.MeasureString(Text, m_font).ToSize();
g.DrawString(Text, m_font, brush,
Const.BulletSize+8, (this.Height - textSize.Height)/2);
}

protected override void OnMouseDown (MouseEventArgs e)
{
base.OnMouseDown(e);
this.Capture = true;

// see if clicked on label text or arrow
if (m_rcHitArea.Contains(e.X, e.Y))
{
m_pushed = true;
Invalidate();
}
}

protected override void OnMouseUp (MouseEventArgs e)
{
base.OnMouseUp(e);
this.Capture = false;
m_pushed = false;
Invalidate();
}

protected override void OnClick(EventArgs e)
{
if (m_pushed)
base.OnClick(e);
}

private void CreateGdiObjects()
{
// gdi objects
m_font = new Font(Const.FontName, Const.FontSize, FontStyle.Bold);
m_penPushed = new Pen(Const.PushedColor);
m_penFore = new Pen(this.ForeColor);
m_penDisabled = new Pen(Const.DisableColor);
m_brushPushed = new SolidBrush(Const.PushedColor);

}

private void CreateMemoryBitmap(Graphics g)
{
// see if need to create gdi objects
if (m_bmp == null || m_bmp.Width != this.Width || m_bmp.Height != this.Height)
{
// memory bitmap
m_bmp = new Bitmap(this.Width, this.Height);

// bullet points
int halfHeight = this.Height/2;
m_bulletPts = new Point[3];
m_bulletPts[0] = new Point(0, halfHeight-(Const.BulletSize/2));
m_bulletPts[1] = new Point(Const.BulletSize, halfHeight);
m_bulletPts[2] = new Point(0, halfHeight+(Const.BulletSize/2));

// hit area
Size textSize = g.MeasureString(Text, m_font).ToSize();
m_rcHitArea = new Rectangle(0,
(this.Height - textSize.Height)/2,
textSize.Width + Const.BulletSize + 8,
textSize.Height);
}
}
}
}

Use the Sync Framework with C#

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
{
public static void Main( string [] args)
{
if (args.Length <>
string .IsNullOrEmpty(args[0]) || string .IsNullOrEmpty(args[1]) ||
! Directory .Exists(args[0]) || ! Directory .Exists(args[1]))
{
Console .WriteLine(
"Usage: FileSyncSample [valid directory path 1] [valid directory path 2]" );
return ;
}

string replica1RootPath = args[0];
string replica2RootPath = args[1];
string idFileName = "filesync.id" ;

SyncId replica1Id = GetReplicaId( Path .Combine(args[0], idFileName));
SyncId replica2Id = GetReplicaId( Path .Combine(args[1], idFileName));

try
{
// Set options for the sync operation
FileSyncOptions options = FileSyncOptions.ExplicitDetectChanges |
FileSyncOptions.RecycleDeletes | FileSyncOptions.RecycleOverwrites;

FileSyncScopeFilter filter = new FileSyncScopeFilter();
filter.FileNameExcludes.Add(idFileName); // Exclude the id file

// Explicitly detect changes on both replicas upfront, to avoid two change
// detection passes for the two-way sync
DetectChangesOnFileSystemReplica(
replica1Id, replica1RootPath, filter, options);
DetectChangesOnFileSystemReplica(
replica2Id, replica2RootPath, filter, options);

// Sync in both directions
SyncFileSystemReplicasOneWay(replica1Id, replica2Id,
replica1RootPath, replica2RootPath, filter, options);
SyncFileSystemReplicasOneWay(replica2Id, replica1Id,
replica2RootPath, replica1RootPath, filter, options);
}
catch ( Exception e)
{
Console .WriteLine( "\nException from File System Provider:\n" + e.ToString());
}
}

public static void DetectChangesOnFileSystemReplica(
SyncId replicaId, string replicaRootPath,
FileSyncScopeFilter filter, FileSyncOptions options)
{
FileSyncProvider provider = null ;

try
{
provider = new FileSyncProvider(replicaId, replicaRootPath, filter, options);
provider.DetectChanges();

finally

Console .WriteLine( "Synchronizing changes to replica: " +
destinationProvider.RootDirectoryPath);
agent.Synchronize();
}
finally
{
// Release resources
if (sourceProvider != null ) sourceProvider.Dispose();
if (destinationProvider != null ) destinationProvider.Dispose();
}
}

public static void OnAppliedChange( object sender, AppliedChangeEventArgs args)
{
switch (args.ChangeType)
{
case ChangeType.Create:
Console .WriteLine( "-- Applied CREATE for file " + args.NewFilePath);
break ;
case ChangeType.Delete:
Console .WriteLine( "-- Applied DELETE for file " + args.OldFilePath);
break ;
case ChangeType.Overwrite:
Console .WriteLine( "-- Applied OVERWRITE for file " + args.OldFilePath);
break ;
case ChangeType.Rename:
Console .WriteLine( "-- Applied RENAME for file " + args.OldFilePath +
" as " + args.NewFilePath);
break ;
}
}

public static void OnSkippedChange( object sender, SkippedChangeEventArgs args)
{
Console .WriteLine( "-- Skipped applying " + args.ChangeType.ToString().ToUpper()
+ " for " + (! string .IsNullOrEmpty(args.CurrentFilePath) ?
args.CurrentFilePath : args.NewFilePath) + " due to error" );

if (args.Exception != null )
Console .WriteLine( " [" + args.Exception.Message + "]" );
}

public static SyncId GetReplicaId( string idFilePath)
{
SyncId replicaId = null ;

if ( File .Exists(idFilePath))
{
using ( StreamReader sr = File .OpenText(idFilePath))
{
string strGuid = sr.ReadLine();
if (! string .IsNullOrEmpty(strGuid))
replicaId = new SyncId( new Guid (strGuid));
}
}

if (replicaId == null )
{
using ( FileStream idFile = File .Open(
idFilePath, FileMode .OpenOrCreate, FileAccess .ReadWrite))
{
using ( StreamWriter sw = new StreamWriter (idFile))
{
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.
