使用SendMessage 模拟鼠标点击

[Game4s]

已知目标窗口的句柄 hWnd
如何根据自定义的X,Y坐标值使用SendMessage向目标窗口发送鼠标点击指令？
请给出实例代码.非常感谢

用mouse_event 函数多好

[Game4s]

自己解决了。
其实关键就是lParam 的格式问题.
前面几位回答的MakeLParam 函数没有尝试过，自己用了个
StrToInt(#36+IntToHex(Y,4)+IntToHex(X,4)))
达到了预期效果。结贴给分了

SendMessage(hWnd, WM_LBUTTONDOWN, MK_LBUTTON, makelparam(x,y));

用RegisterwindowMessage注冊唯一窗口标识
send方
var
Form1: TForm1;
UserMessage:UINT;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);
begin
SendMessage(FindWindow('TForm1','RegisterMessage Get Example'),UserMessage,0,0);
//'RegisterMessage Get Example'接受窗口名字caption
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
UserMessage:=RegisterwindowMessage('System Wide User Defined Message');
end;

get方：
var
Form1: TForm1;
UserMessage:UINT;

implementation

{$R *.dfm}

procedure TForm1.DefaultHandler(var Msg);
begin
inherited DefaultHandler(Msg);

if (TMessage(Msg).Msg=UserMessage) then
begin
button1.Click;
end;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
UserMessage:=RegisterWindowMessage('System Wide User Defined Message');
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
showmessage('ok');
end;

SendMessage(hwnd, WM_LBUTTONDOWN, MK_LBUTTON, makelparam(x,y));

GetCursorPos(m);是取鼠标位置。
WindowFromPoint(m)是取M坐标点处的句柄，在这里当然也就是鼠标的位置。
sendMessage(WindowFromPoint(m), WM_LBUTTONDOWN, 0, 0);
SendMessage(WindowFromPoint(m), WM_LBUTTONUP, 0, 0);

SendMessage(hWnd,WM_LMOUSEDOWN,x,y);
