Loading a bitmap in a CStatic

[Anish Mistry]

How would i load a resource bitmap into a CStatic? Thanks.

1. Lay a static control to a dialog box.
2. At property setting, change the Type attribute to "Bitmap".
3. Assign resource ID to Image attribute.

and if I want to do it dynamically?

You can SetBitmap function of CStatic class.
You can associate your static control to a member veriable of CStatic class at "Member Variables"
section of Class Wizard.

search help for ::LoadImage(). This function does what you want.

I have just tried using your suggestion for a modal dialog box, but get an ASSERTion failure (NULL hWnd) from SetBitmap(). My code is:

HBITMAP hBitmap = ::GetTrackSymbol( tempBitmap, PPLI_AIR, tempStr );
d_Filters->m_Page1.m_ppli_air.SetBitmap( hBitmap );

if(d_Filters->DoModal()==IDOK) {




This is in the event handler for the menu item to open the dialog. GetTrackSymbol() returns a handle to either the built-in resource or a bitmap in a file in the folder named in tempStr.

what i would like 2 know is how do i change the image in a CStatic (bitmap) as a result of some event in the dialog box (eg: different radio buttons). i have tried everything. somebody help me

Try this on your event procedure :
[CBitmap bitmap;
bitmap.LoadBitmap(IDB_YOUR_SPECIAL_BITMAP);
m_static.SetBitmap((HBITMAP)bitmap);]
Please let me know if it works

If you want to load the bitmap from a file use:


hBitmap = (HBITMAP) ::LoadImage(AfxGetInstanceHandle(), iconPath, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION);




then use SetBitmap(hBitmap)

The problem I'm having is that I am unable to free the resources when the dialog containing the CStatics are destroyed. Calling DeleteObject()

also deletes the bitmap of which hBitmap is the handle. This is not what I want as that bitmap is used in the main part of the app.

Does anyone know how to free resources after a SetBitmap call?

I used your code for changing the bitmap in the static control and the static control changes to the new image size, but the control is blank. Help!
