GDI：CreateDIBSection / CreateDIBitmap几个小时后失败 [英] GDI: CreateDIBSection/CreateDIBitmap Failed after several hours

问题描述

大家好，

我在Window 7上开发了一个带有GDI / MFC的deskstop应用程序。 

I developed a deskstop app with GDI/MFC on Window 7. 

此应用程序加载了每5秒的图像。它在4-5h后崩溃，我在CreateDIBSection中得到了ERROR_INVALID_PARAMETER。

This app loads an image per 5s. It crashed after 4-5h and I got ERROR_INVALID_PARAMETER in CreateDIBSection.

以下是代码：

UINT local_colors = 2;

UINT local_colors = 2;

RGBQUAD image_colormap [2];

RGBQUAD image_colormap[2];

image_colormap [0] .rgbRed =  image_colormap [0] .rgbGreen =  image_colormap [0] .rgbBlue = 0;

image_colormap[0].rgbRed = image_colormap[0].rgbGreen = image_colormap[0].rgbBlue = 0;

image_colormap [1] .rgbRed =  image_colormap [1] .rgbGreen =  image_colormap [1] .rgbBlue = 255;

image_colormap[1].rgbRed = image_colormap[1].rgbGreen = image_colormap[1].rgbBlue = 255;

UINT local_bmpInfo_size = sizeof（BITMAPINFO）+ local_colors * sizeof（RGBQUAD）;;

UINT local_bmpInfo_size = sizeof(BITMAPINFO) + local_colors * sizeof(RGBQUAD);;

LPBITMAPINFO local_bmpInfo =（LPBITMAPINFO）malloc（local_bmpInfo_size）;

LPBITMAPINFO local_bmpInfo = (LPBITMAPINFO ) malloc(local_bmpInfo_size);

CopyMemory（local_bmpInfo-> bmiColors，image_colormap，local_colors * sizeof（RGBQUAD））;

CopyMemory(local_bmpInfo->bmiColors, image_colormap, local_colors* sizeof(RGBQUAD));

HDC local_hDC = :: GetDC（NULL）;

HDC local_hDC = ::GetDC(NULL);

if（local_hDC）

if(local_hDC)

{

UCHAR *  image_bits = NULL;

UCHAR* image_bits = NULL;

HBITMAP local_imgHandle =  CreateDIBSection（local_hDC ，local_bmpInfo，DIB_RGB_COLORS，（void **）& image_bits，NULL，0l）;

HBITMAP local_imgHandle = CreateDIBSection(local_hDC , local_bmpInfo, DIB_RGB_COLORS, (void**)&image_bits, NULL, 0l);

}

:: Release（NULL，local_hDC）;

::Release(NULL,local_hDC);

您有什么想法吗？
