Loading bitmap file into HBITMAP

[AcarX]

I'm trying to load a .bmp file into a HBITMAP using LoadImage but it doesn't seem to work.

HBITMAP b = (HBITMAP)LoadImage(0, "c:\\image.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);
	if (b)
		MessageBox(0,"loaded", 0, 0);

Is there any other way to do it ?

Another way to do it? Sure.

Easier? Probably not.

Use this function to debug:

void ErrorExit(PTSTR lpszFunction) 
//from https://msdn.microsoft.com/en-us/library/windows/desktop/ms682499(v=vs.85).aspx
// Format a readable error message, display a message box, 
// and exit from the application.
{ 
    LPVOID lpMsgBuf;
    LPVOID lpDisplayBuf;
    DWORD dw = GetLastError(); 

    FormatMessage(
        FORMAT_MESSAGE_ALLOCATE_BUFFER | 
        FORMAT_MESSAGE_FROM_SYSTEM |
        FORMAT_MESSAGE_IGNORE_INSERTS,
        NULL,
        dw,
        MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
        (LPTSTR) &lpMsgBuf,
        0, NULL );

    lpDisplayBuf = (LPVOID)LocalAlloc(LMEM_ZEROINIT, 
        (lstrlen((LPCTSTR)lpMsgBuf)+lstrlen((LPCTSTR)lpszFunction)+40)*sizeof(TCHAR)); 
    StringCchPrintf((LPTSTR)lpDisplayBuf, 
        LocalSize(lpDisplayBuf) / sizeof(TCHAR),
        TEXT("%s failed with error %d: %s"), 
        lpszFunction, dw, lpMsgBuf); 
    MessageBox(NULL, (LPCTSTR)lpDisplayBuf, TEXT("Error"), MB_OK); 

    LocalFree(lpMsgBuf);
    LocalFree(lpDisplayBuf);
    ExitProcess(1);
}

Is it a 32-bit bitmap? Try LR_CREATEDIBSECTION?

@Homberto
Thanks for the answer. But I'm using VS 2013 Express which doesn't support resource editing so i'm trying to avoid that as much as possible. When i use:

	HBITMAP b = (HBITMAP)LoadImage(0, "image.bmp", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);
	if (!b)
		ErrorExit(0);

This is what i get:

(null) failed with error 0: The operation completed successfully.

I thought that maybe it was actually working but when i use:

	SIZE bsize = { 0 };
	GetBitmapDimensionEx(b, &bsize);
	std::string dm = std::to_string(bsize.cx);
	MessageBoxA(0, dm.c_str(), 0, 0);

I get 0 as output.

@RaduV That didn't work out sadly.

So, what exactly isn't working? What's the value of b?
To debug variable values do this:

AllocConsole();
freopen("CONOUT$", "w", stdout);
std::cout << b; //#include <iostream> of course

Hi. Just installed a version of VS which supports resource editing. I was abled to achieve my goal using your link. Thanks very much.
