因要做一個小的登陸客戶端,所用圖片格式為png.但較少,所以想直接放到資源中.
碰到的第一個問題是.net2003中加載png圖片到資源中總是不成功.試了下發現jpg也不行,jpg圖片會提示"不是正確的JPEG格式",后來用vc6.0打開資源文件加載成功的.vs2003中原因還未找到,有知道的朋友告知一聲.
而后的問題就是如何把資源中的二進制的圖片數據顯示出來.?? gg之.整理代碼如下:
?1
????Image?*pRetImg?=?NULL;
?2????
?3????HGLOBAL????????hGlobal?=?NULL;
?4????HRSRC????????hSource?=?NULL;
?5????LPVOID????????lpVoid??=?NULL;
?6????int????????????nSize???=?0;
?7
?8????hSource?=?FindResource(AfxGetResourceHandle(),?MAKEINTRESOURCE(IDR_BACK_PNG),?"PNG");
?9
10????if(hSource?==?NULL)
11????????return?pRetImg;
12
13????hGlobal?=?LoadResource(AfxGetResourceHandle(),?hSource);
14????if(hGlobal?==?NULL)
15
????
{????
16
????????FreeResource(hGlobal);?????????return?pRetImg;????????
17
????}
18
19????lpVoid?=?LockResource(hGlobal);
20????if(lpVoid?==?NULL)
21????????goto?Exit;
22
23????nSize?=?(UINT)SizeofResource(AfxGetResourceHandle(),?hSource);
24
25????HGLOBAL?hGlobal2?=?GlobalAlloc(GMEM_MOVEABLE,?nSize);
26????if(hGlobal2?==?NULL)
27????{
28????????goto?Exit;
29????}
30
31????void*?pData?=?GlobalLock(hGlobal2);
32????memcpy(pData,?(void?*)hGlobal,?nSize);
33????GlobalUnlock(hGlobal2);
34
35????IStream*?pStream?=?NULL;
36
37????if(CreateStreamOnHGlobal(hGlobal2,?TRUE,?&pStream)?==?S_OK)
38????{
39
40????????pRetImg?=?Image::FromStream(pStream,?FALSE);
41????????pStream->Release();
42????}
43
44????FreeResource(hGlobal2);?
45
46
47Exit:
48????UnlockResource(hGlobal);????FreeResource(hGlobal);?
49????return?pRetImg;
50
