pImage->LoadFrame(..) crashing when replaced custom Toolbar.bmp in MDI application

Question

See more:

C++

CMDIFrameWnd* pFrame = new CMainFrame;
if (!pFrame)
    return FALSE;
m_pMainWnd = pFrame;
// create main MDI frame window
if (!pFrame->LoadFrame(IDR_MAINFRAME))
    return FALSE;

I have created MDI application which has one toolbar (With 5 buttons, coming through a Toolbar.bmp image)

Now, instead of showing the default images, I want to show my custom ones and replaced the used toolbar bitmap with my new; But surprisingly it is crashing in pImage->LoadFrame(..);

Any Idea why it is crashing? I just replaced the BMP image with same number of buttons!! (Custom Toolbar.bmp)

Thanks

Quite possibly (probably?) an issue with image encoding. I'd check the following:
1) Dimensions
2) Bit depth
3) Byte ordering - rgb or bgr

1) Dimensions are different: Previously 80x15, now 160 x 32
2) Bit Depth: Previously 4, now 24
3) Both RGB

I have to use this BMP, no clue how to fit this current projet? Dimensions are not problem as this can be modified;

I'll assume this was intended for me (as is the only sane thing to do) - You should hit the ( "<- Reply" button to the right of a person's comment to respond to them. The "Have a Question or Comment" button is for responding to the original question, or a solution. Whichever the button follows.

Anyhow, the problem is the bit-depth. MFC organizes an internal image-list to hold the bitmaps. It's a 4 bit image list...

Here's a solution at stackoverflow: Higher bit-depth for MFC toolbar icons
