CodePudding user response:

Pay attention to the single forward slash, or easy to escape, or easy to eat, to the double slash,

CodePudding user response:

Has been changed to double slash, but display bitmap or not, I set a breakpoint debugging and judge if there is no go in, so there was no image display

LoadBitmap
The LoadBitmap function loads The specified bitmap resource the from a module 's the executable file. This function has had been superseded by theLoadImage function.

HBITMAP LoadBitmap (
HINSTANCE HINSTANCE,//handle to the application instance
LPCTSTR lpBitmapName//address of the bitmap resource name
);
Such as
HBitmap=LoadBitmap (hInstance, MAKEINTRESOURCE (IDB_BITMAP1));

CodePudding user response:

HImage=LoadImage (NULL, ofn. LpstrFile IMAGE_BITMAP, 0, 0,
LR_LOADFROMFILE | LR_CREATEDIBSECTION);

Slash paths are obstacle

CodePudding user response:

CImage: : the Load () is the most simple, or use the API LoadImage

CodePudding user response:

Can a breakpoint IF place, look at the path is normal
