描述:
我是在Win32 Service程序中创建了一个隐含窗口，然后在另外一个对话框程序中查找这个隐含窗口，
在2000/XP 下，用VC自带的Spy＋＋可以看到这个隐含窗口，可是在2003 Server中就看不到（可是创建窗口已经成功了），这是为什么？
服务程序如下：
void AgIceRunService(AGICE_VOID)
{
//COPYDATASTRUCT pcds;
MSG msg;
//create window to handle msgs
hWnd = AgIceBuildHiddenWindow();
if(AGICE_NULL == hWnd)
{
AGICE_WRITE_LOG(0, "Failed to create window for service!\n");
return;
}
else
{
AGICE_WRITE_LOG(0, "Successful to create window for service!\n");
}
AGICE_WRITE_LOG(0, "Begin to handle windows msg!\n");
while(-1 != GetMessage(&msg, hWnd, 0, 0))
{
AGICE_WRITE_LOG(0, "Handle window msg after receiving it!\n");
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
