怎样自己控制窗体的消息循环,例如在其中“吃掉”发给某个控件的鼠标消息? 如题 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 用TApplicationEvents控件。例如:procedure TForm1.ApplicationEvents1Message(var Msg: tagMSG; var Handled: Boolean);begin if Msg.Handle = Button1.Handle then begin 。。 Handled := TRUE; end;end;Msg结构:TMsg = packed record hwnd: HWND; message: UINT; wParam: WPARAM; lParam: LPARAM; time: DWORD; pt: TPoint; end; //关于消息祥解.http://expert.csdn.net/Expert/topic/2278/2278663.xml?temp=.2748834 覆盖wndproc方法应该也可以吧,可是怎么没有效果呢 要是只是拦截特定的 消息的话procedure yourmessageHandle (var msg:TMsg);message yourMessage;begin if msg.message=yourmessage then abort else inherited;end; 哎,我想拦截的是realAudio控件的右键单击消息,不让他弹出菜单,不知道怎么拦 可以这么拦截:procedure TForm1.ApplicationEvents1Message(var Msg: tagMSG; var Handled: Boolean);begin if Msg.message = WM_RBUTTONDOWN then if PtInRect( Rect(realAudio.Left + Left, realAudio.Top + Top, realAudio.Width + realAudio.Left + Left, realAudio.Height + realAudio.Top + Top), Point(Mouse.CursorPos.X,Mouse.CursorPos.Y ) ) then begin Handled := TRUE; end;end; C# 操作PDF 大括号注释的问题 大家面试 delphi的时候,都被问什么问题啊? 代碼寫好后,如何生成控件? 这样的SQL语句怎么转化? delphi能不能用代码直接打印,不经过qreport 用delphi怎么修改注册表中某个键值的值呢??? DBGrid两问 请各位高手帮忙!!! 质疑CSDN的客户端程序!小弟有几个问题,不知道放在哪个版好,听说CSDN的客户端程序是Delphi写的,所以先放在这里吧! 如何在DBGrid上显示记录的顺序号??? 怎样显示??????????????
例如:
procedure TForm1.ApplicationEvents1Message(var Msg: tagMSG;
var Handled: Boolean);
begin
if Msg.Handle = Button1.Handle then
begin
。。
Handled := TRUE;
end;
end;
Msg结构:
TMsg = packed record
hwnd: HWND;
message: UINT;
wParam: WPARAM;
lParam: LPARAM;
time: DWORD;
pt: TPoint; end;

procedure yourmessageHandle (var msg:TMsg);message yourMessage;
begin
if msg.message=yourmessage then
abort
else
inherited;
end;
procedure TForm1.ApplicationEvents1Message(var Msg: tagMSG;
var Handled: Boolean);
begin
if Msg.message = WM_RBUTTONDOWN then
if PtInRect( Rect(realAudio.Left + Left,
realAudio.Top + Top,
realAudio.Width + realAudio.Left + Left,
realAudio.Height + realAudio.Top + Top),
Point(Mouse.CursorPos.X,Mouse.CursorPos.Y ) ) then
begin
Handled := TRUE;
