Problem with loading JPEG file from resources in MFC C++ application

Question

The following code works correctly under Windows XP:

CImage image;

RECT destRect;

int nResource = 10;

CResourceStream stream(0, MAKEINTRESOURCE(nResource), _T("JPEG"));

HRESULT hr = image.Load(&stream);

image.Draw(hDC, destRect);

But on Windows 7 image.Load returns E_FAIL though creating CResourceStream reads JPEG file from resources correctly.

Debugging gives the following result:

GdipCreateBitmapFromStream returns InvalidParameter.

What the problem can be?

JPEG is a custom category in resource file.

Answer 1

I believe you should use "JPG" not "JPEG".

Answer 2

At the end I used this solution from codeproject:

It is a thin wrapper for GDI+ which is able to load JPEG files (and others) under Windows 7 perfectly.
