LoadImage传参问题
win32应用项目 loadImage函数返回值为空错误
Environment:
// VS2005 + SDK-WINCE5.0
m_hBmpPush1=LoadImage(m_hInst,_T("D:\\testgid\ccc.bmp"),IMAGE_BITMAP,0,0,LR_DEFAULTCOLOR);
if(m_hBmpPush1==NULL)
{
DrawText(hdc,_T("加载失败"),-1,&buttonimg1,m_uFormat);
}
[解决办法]
GetLastError看看是什么原因
[解决办法]
HBITMAP bmp =(HBITMAP)::LoadImage(AfxGetInstanceHandle(),str_path,IMAGE_BITMAP,0, 0, LR_CREATEDIBSECTION | LR_LOADFROMFILE); if(bmp==NULL) { MessageBox("LoadImage Error !"); return FALSE; }
[解决办法]
Try this
m_hBmpPush1=LoadImage(NULL,_T("\\StaticStore\\testbutton\\ccc.bmp"),IMAGE_BITMAP,0,0,LR_DEFAULTCOLOR|LR_LOADFROMFILE);

对了,楼主,你的BMP文件是不是有效的BMP啊?
得是规范的bmp了,别直接修改一个扩展名比如1.png -> 1.bmp就直接拿来用了

我试了下 的确有些问题 我用VS2008和VC6.0虽然句柄不为0 但还是显示不出来 大家还是试一下 成功了再发代码
这是VS2008的MSDN
hinst
[in] Handle to the module of either a DLL or executable (.exe) that contains the image to be loaded. For more information, see GetModuleHandle. Note that as of 32-bit Microsoft Windows, an instance handle (HINSTANCE), such as the application instance handle exposed by system function call of WinMain, and a module handle (HMODULE) are the same thing.
To load an OEM image, set this parameter to NULL.
To load a stand-alone resource (icon, cursor, or bitmap file)—for example, c:\myimage.bmp—set this parameter to NULL.

是不是写在DLL里面的?
