Question

vc的PICTURE控件怎么用？我想按下一个 按钮之后，picture中的图片就变了

Answer 1

原型：
int WINAPI icePub_dispImg(HWND hWnd,char *strImgFilename,int x,int y)
输入：hWnd 窗体或控件句柄
strImgFilename 待显示的图片文件名
x x坐标
y y坐标
输出：

{
typedef int (WINAPI ICEPUB_DISPIMG)(HWND hWnd,char *strImgFilename,int x,int y);
ICEPUB_DISPIMG *icePub_dispImg = 0;
HINSTANCE hDLLDrv = LoadLibrary("icePubDll.dll");
if(hDLLDrv)
{
icePub_dispImg = (ICEPUB_DISPIMG *)GetProcAddress(hDLLDrv, "icePub_dispImg");
}

if(icePub_dispImg != NULL)
icePub_dispImg(m_hWnd,"b.png",10,10);
// icePub_dispImg(m_ctrlText.m_hWnd,"b.jpg",0,0);
if(hDLLDrv)
FreeLibrary(hDLLDrv);
}

还有简单一点的吗

追答

extern "C"
{
__declspec(dllexport)
int WINAPI icePub_dispImg(HWND hWnd,char *strImgFilename,int x,int y);

}

#pragma comment(lib,"icePubDll.lib")

icePub_dispImg(m_hWnd,"b.png",10,10);
