在BCB中怎样实现用->（右箭头）键代替TAB键？？
还有一个问题：
如何知道当前按下的是哪个键，

[whitelion]

你截获->按下的消息，然后编程实现光标的定位

[ThinkX]

1.将form的科研KeyPreview属性设置成true
2.在form的OnKeyDown事件中写入
if (Key == VK_RIGHT)
{
Key = 0;
Perform(WM_NEXTDLGCTL, 0, 0);
}
3.通过Key就可以知道按的是哪个键，Key的值可以查MSDN的虚拟键值

[Spring414]

void __fastcall TForm1::Edit1KeyDown(TObject *Sender, WORD &Key,
TShiftState Shift)
{
if( Key==39 ) //Left
{
Edit1->Text=Key;
keybd_event(9,NULL,NULL,NULL); //按下//Tab
keybd_event(0,0,KEYEVENTF_KEYUP,0);//放开
}
}

[CyberUFO]

在form的OnKeyDown事件中写入

void __fastcall TfrmMain::FormKeyPress(TObject *Sender, char &Key)
{
if(Key==VK_RIGHT)
SendMessage(Handle,WM_NEXTDLGCTL,0,0);
}

注意： Form的KeyPreview属性一定要记得设为True！！！
