为什么该函数在TDbCtrlGrid中的控件中用enter代替tab不管用？（即用该函数不能等同与按下<br><br>下Tab键？？？）请高手指教

这个方法不行。有没有别的？<br>怎样完全（完全）模拟当按下Enter键时用Tab键代替？perform(cm_dialogkey,vk_tab,0)一旦<br>遇上button控件就停在Button上不移动了，请问，这到底为啥？？？？<br>

SelectNext(ActiveControl, &nbsp; &nbsp; &nbsp;true, &nbsp; &nbsp; True);<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;↑ &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ↑ &nbsp; &nbsp; &nbsp; &nbsp; ↑<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;CurrentControl, GoForward, CheckTabStop<br>还可以发送消息：<br>&nbsp; &nbsp; &nbsp; PoseMessage(Handle,WM_NextDLGCTL,0,0)<br>焦点在Button上的时候对Button是没有用的，<br>可以用AppcationEvents，在OnMessage里面抢先处理按键就行了。

我做了一个控件Xkey，用Enter键实现Tab的功能，非常简单，<br>但是没有处理在Button上的情况，如果你愿意将它改一改，<br>我可以发给你，需要的话请发邮件到 yang_gq@163.net

&nbsp; &nbsp;在OnKeyDowm事件中加入一下代码，如在From上实现请将KeyPreview设为True.<br>&nbsp; &nbsp; if Key = VK_Return then<br>&nbsp; &nbsp; begin PERFORM(WM_NEXTDLGCTL,0,0) end;<br>&nbsp; &nbsp; 对DBGrid中或Button中的处理，请在相应事件中编写代码。<br>

PERFORM(WM_NEXTDLGCTL,0,0) 和PoseMessage(Handle,WM_Keydown,Vk_tab,0)<br>不能用在DBCtrlGrid中。<br>以下<br>来自：Pipi. 时间：00-3-3 0:07:56 ID:194093 &nbsp;<br>我是这样的：<br>form.KeyPrew 设置为 true<br>在form的 OnShortCut 事件里面<br>if(msg.CharCode=VK_RETURN)then<br>&nbsp; msg.CharCode:=VK_TAB;<br><br>&nbsp;<br>&nbsp;<br>
