BMP image displayed by VC

 

Method 1:

1) modify the picture control attribute

2) directly associate with the image: Set the image attribute

3) change the type to bitmap.

Method 2: (pictureex online search)

1) Add the control variable as a pictureex object.

2) directly m_pic1.loadbitmap (idb_bitmap1 );

Example:

1. Associate the picture control object: m_stpicture

2. Add two BMP resources: idb_bitmap1 and idb_bitmap2.

3. Definition: hbitmapm_hbitmap;

4. Show the image at the beginning

Bool cshowbmp DLG: oninitdialog ()

{

Cdialog: oninitdialog ();

......

// Display the image

M_hbitmap = (hbitmap) LoadImage (AfxGetInstanceHandle (), makeintresource (idb_bitmap1), image_bitmap, 0, 0, lr_loadmap3dcolors );

M_stpicture.modifystyle (0xf, ss_bitmap );

M_stpicture.setbitmap (m_hbitmap );

Return true; // return true unless the control focus is set.

}

5. Switch Images

Void cshowbmp DLG: onbnclickedok ()

{

Static int nid = 0;

NID ++;

If (null! = M_hbitmap)

{

: Deleteobject (m_hbitmap );

M_hbitmap = NULL;

}

Int npicid = nid = NID % 2? Idb_bitmap2: idb_bitmap1;

M_hbitmap = (hbitmap) LoadImage (AfxGetInstanceHandle (), makeintresource (npicid), image_bitmap, 0, 0, lr_loadmap3dcolors );

M_stpicture.modifystyle (0xf, ss_bitmap );

M_stpicture.setbitmap (m_hbitmap );

}
