How to load bitmap on Windows Mobile

How to load bitmap on Windows Mobile

 

Currently, I only know three methods.

I. loadbitmap

Function:

You can load a specified bitmap from an execution module.

Prototype:

HBITMAP LoadBitmap(

  __in  HINSTANCE hInstance,

  __in  LPCTSTR lpBitmapName

);

Parameters:

Hinstance [in]

Module handle containing bitmap

Lpbitmapname [in]

A string ending with '/0', containing the name of the resource to be loaded as a bitmap. You can use makeintresource to convert the resource ID.

Return Value:

If yes, a bitmap handle is returned. Otherwise, null is returned.

Note:

If the file name does not exist or the memory is insufficient, function execution fails.

Call deleteobject to delete a loadbitmap object.

Example:

Hbitmap = loadbitmap (g_hinstance, makeintresource (idb_bmp ));

Ii. shloadimageresource

Function:

Converts a view file to a bitmap file. The view resource file must be included in the resource file.

Prototype:

HBITMAP SHLoadImageResource (

HINSTANCE hinst,

UINT uIdImageFile

);

Parameters:

Hinst

[In] Resource handle

Uidimagefile

[In] View File number

Return Value:

If yes, a bitmap handle is returned. Otherwise, null is returned.

Note:

The conversion file types include GIF, PNG, JPG, ICO, and BMP.

When the shloadimageresource object is no longer used, call deleteobject to delete the object.

Example:

Hbitmap = shloadimageresource (g_hinstance, idr_image );

Iii. shloadimagefile

Function:

Read the View File, decompress it, and return the bitmap handle.

Prototype:

HBITMAP SHLoadImageFile (

  LPCTSTR pszFileName

);

Parameters:

pszFileName 

[In] View File name to be loaded

Return Value:

If yes, a bitmap handle is returned. Otherwise, null is returned.

Note:

The conversion file types include GIF, PNG, JPG, ICO, and BMP.

When the shloadimageresource object is no longer used, call deleteobject to delete the object.

Example:

Hbitmap hbmp = shloadimagefile (

(Text ("// my documents // my pictures // waterfall.jpg ")));
