如何得到当前活动应用程序的句柄

[chen780831]

用什么函数？

[lanlijing]

试一试：
HANDLE handle;
handle=::GetModuleHandle(NULL);

//寻找一个正在运行程序的句柄，并向其发送消息
CString strCaption;
CString caption("记事本");
ASSERT_VALID (AfxGetMainWnd ());
pWnd=AfxGetMainWnd ()->GetWindow (GW_HWNDFIRST);
BOOL blnHaveFind=false;
while (pWnd)
{
if (pWnd ->IsWindowVisible()&& pWnd ->GetWindowTextLength ()&&! pWnd ->GetOwner ())
{

pWnd ->GetWindowText (strCaption);
if(strCaption.Find(caption.GetBuffer(0),0)!=-1)
{
blnHaveFind=true;
hwd = pWnd->GetSafeHwnd();
//发送消息
::SendMessage(hwd,WM_SYSCOMMAND,SC_RESTORE,NULL);//
//设置为激活的窗体
::SetForegroundWindow(hwd);
//找到里面的Edit
HWND hwnd1=FindWindowEx(hwd,NULL,"Edit",NULL);
//ASSERT(hwnd1);break;
//写字"I Love You!"
::SendMessage(hwnd1,WM_SETTEXT,NULL,(LPARAM)"I Love You");
break;
}
}
//Get next window in window list.
pWnd=pWnd ->GetWindow(GW_HWNDNEXT);
}

注意：pWnd为CWnd型并且必须定义为全局变量
注意: AfxGetMainWnd不必用全局函数

::GetForegroundWindow() !

如果还要进程的句柄就接着：
::GetWindowThreadProcessId(hwndForeground,&dwProcessId);
hProcess=OpenProcess(dwProcessId);
