QQ自动发消息源码

-
delphi代码
procedure TForm1.Button1Click(Sender: TObject);
var
hParent,hButton,hMemo: HWND;
begin
Memo1.CopyToClipboard;//把Memo中选中的语句拷贝到剪贴板中
try
//找发送消息的QQ窗口
hParent := FindWindow(nil, '发送消息');
//然后找回话时用的编辑窗口,Point函数用于返回一个TPoint类型变量
hMemo := ChildWindowFromPointEx(hParent, Point(50, 100), CWP_ALL);
//找到“送讯息”按钮的句柄
hButton := FindWindowEx(hParent,0,nil,'送讯息(&S)');
if (hParent = 0) or (hMemo = 0) or (hButton = 0) then
MessageBox(Handle,'没有找到发送窗口，请重试！','错误',MB_ICONWARNING)
else
begin
//向发送消息中的回话编辑框发送粘贴消息
SendMessage(hMemo,WM_PASTE,0,0);
//向“送讯息”按钮送单击消息以模仿按键发送回话
SendMessage(hButton,BM_CLICK,0,0);
end;
except
//如果发生以外错误给出提示
MessageBox(Handle,'发送消息出错，请重试！','错误',MB_ICONWARNING);
end;
