How to load a bmp file in visual studio 2010

Question

I am pretty new to Visual Studio C++. I am trying to load a bmp file from my system with specific path and show it on picture control in mfc, but m unable to do so. Can any one guide me here. I tried the following but i am getting an error..

Code:

filePath = "images/0000.4d.bmp";
ASSERT(filePath);

HBITMAP hBitmap= NULL;
hBitmap = (HBITMAP) LoadImage (
  0, 
  filePath, 
  IMAGE_BITMAP, 
  0, 0, 
  LR_LOADFROMFILE | LR_CREATEDIBSECTION | LR_DEFAULTSIZE);


IDB_PICTURE2.LoadBitmapW(MAKEINTRESOURCE(hBitmap));
m_picture.SetBitmap(IDB_PICTURE2);

The error occurs when I am trying to load the bmp file. Thank you.

First test that your hBitmap that it's not NULL then just call:

m_picture.SetBitmap( hBitmap );

Other:

1. IDB_PICTURE2 is just a #define in your resource.h file. At compile time it'll just be replaced with a number, ie it's not a class you can call methods on.
2. MAKEINTRESOURCE is for converting a resource id into a LPCTSTR for use with methods. It does not turn a hBitmap into a resource.
3. The 'error' you list is just some debug information. It's not the actual error. If LoadBitmap returns NULL call GetLastError for extra information.
