How to use. NET Compact framework in Windows Mobile to retrieve the icon from the execution File

Requirement

You need to read the icons of other execution files, and thenProgram.

 

Implementation

 Class  Extracticon
 {
 Public static  Bitmap Getbitmapfromeicon ( String Path)
{
 Return Getbitmap (geticonfromexe (PATH ));
}

 Public static  Icon Geticonfromexe ( String Path)
{
 Return Geticonfromexe (path, True );
}

 // Http://www.pinvoke.net/default.aspx/shell32/ExtractIconEx.html
  Public static  Icon Geticonfromexe ( String Path, Bool Large)
{
 Intptr Hlargeicon = Intptr . Zero;
Intptr Hsmallicon = Intptr . Zero;
Extracticonex (path, 0, Ref Hlargeicon, Ref Hsmallicon, 1 );
 If (Large)
{
 Return ( Icon ) Icon . Fromhandle (hlargeicon). Clone ();
}
 Else
 {
 Return ( Icon ) Icon . Fromhandle (hsmallicon). Clone ();
}
}

  Public static  Bitmap Getbitmap ( Icon Icon)
{
 Bitmap BMP = New  Bitmap (Icon. Width, icon. Height );

 // Create temporary graphics
  Graphics Gxmem = Graphics . Fromimage (BMP );

 // Draw the icon
 Gxmem. drawicon (icon, 0, 0 );

 // Clean up
 Gxmem. Dispose ();

 Return BMP;
}

 Private Static extern  Intptr Extracticonex ( String Filename, Int Index, Ref  Intptr Hiconlarge, Ref  Intptr Hiconsmall, Uint Nicons );
}

Ms provides the extracticonex function to retrieve the ICO icon information of the execution file. The third parameter is a large icon, and the fourth parameter is a small icon.

Because the icon object cannot be directly drawn on graphics, it needs to be converted to bitmap, but Compact framework does not support icon. Save (), soBitmapGetbitmap (IconIcon) function.

Take out the word icon as follows.
