Problem with loading a bitmap with the LoadImage() function

I develop an application in C++ on Windows CE 2013.

I want to load a bitmap from file and show it on-screen.

The problem is the LoadImage() function always returns NULL.

HDC hdcOkno;
hdcOkno = GetDC(hWnd);
HBITMAP hbmObraz;
hbmObraz = (HBITMAP)LoadImage(NULL, L"C:\\Users\\tykab\\OneDrive\\Pulpit\\bitmapy\\background_blue.bmp", IMAGE_BITMAP, 0, 0, NULL);
BITMAP bmInfo;
GetObject(hbmObraz, sizeof(bmInfo), &bmInfo);
BitBlt(hdcOkno, 50, 50, bmInfo.bmWidth, bmInfo.bmHeight, hdcOkno, 0, 0, SRCCOPY);

Update:

Since you are working on Windows CE platform, LoadImage() can not load bitmaps from files. You should use SHLoadDIBitmap() instead.

Original Answer:

From the LoadImage documentation:

name

Type: LPCTSTR

...

If the hinst parameter is NULL and the fuLoad parameter omits the LR_LOADFROMFILE value, the lpszName specifies the OEM image to load...

...

If the fuLoad parameter includes the LR_LOADFROMFILE value, lpszName is the name of the file that contains the stand-alone resource (icon, cursor, or bitmap file). Therefore, set hinst to NULL.

You are not specifying the LR_LOADFROMFILE flag in the fuLoad parameter. The last parameter should be set to the following when loading a file:

LR_DEFAULTSIZE | LR_LOADFROMFILE

As mentioned in the comments, it's always a good idea to check GetLastError() on errors.
