GDI+
-
hi. i want to write an image processing program and i don't need to preview the image so i decided to use win32 console application to avoid any unwanted delays. i want to use GDI+ classes but there is a runtime error. my program :
#include "stdafx.h"
#include ;
#include ;
using namespace Gdiplus;
int main()
{
Bitmap *bmp;
bmp = new Bitmap(L"my image path");
unsigned int w = bmp->GetWidth(); // the error occurs in this line// my process //... return 0;}
the error : Unhandled exception at 0x00411761 in GdiPlusTest.exe: 0xC0000005: Access violation reading location 0x00000004. any help? thanks.

Hey, you're in the un-managed world here. :-D Probably the bitmap object it is incorrectly built because you've not initialized, as required, the
GDI+library (MSDN [^]):You must call GdiplusStartup before you create any GDI+ objects, and you must delete all of your GDI+ objects (or have them go out of scope) before you call GdiplusShutdown.

You have to initialize GDI+ before you make any GDI+ calls. check GdiplusStartup()[^] function

Looks like the missing initialization didn't pass unnoticed... :-D
