问题描述
大家好，我正准备使用wm_copydata在2个应用程序之间进行通信.
我不确定如何使用COPYDTASTRUCT通过HWND.
Hello all, I am tring to communicate between 2 applications using wm_copydata.
I am not sure how to pass HWND using COPYDTASTRUCT.
HWND hWnd = FindWindow(NULL, "Advisor");
if (hWnd)
{
/////Sending Application.
COPYDATASTRUCT cds;
ZeroMemory(&cds, sizeof(COPYDATASTRUCT));
cds.dwData = WM_CREATE;
cds.lpData = (HWND)ResulthWnd;
cds.cbData = sizeof(ResulthWnd);
SendMessage(hWnd,WM_COPYDATA,(WPARAM)ResulthWnd,(LPARAM)&cds);
}
////////Receiving Application
switch (pCopyDataStruct->dwData)
{
case WM_CREATE:
HWND SenderWnd = (HWND)pCopyDataStruct->lpData;
break;
}
有人可以帮忙吗?
