单击任何按钮时如何取消激活输入密钥 [英] How do I deactive enter key when I click any button

问题描述

我做了（0~9）个按钮，因为我想点击按钮（而不是在键盘上按下它）

ex：我点击btn5然后textbox1.text& =5

。但是当我点击任何按钮然后按下回车键（按钮将自动按下并且我不想要的东西）



我尝试了什么：



i只是通过点击按钮而不使用任何键（在键盘上）试图在文本框上书写

解决方案

你真的不应该这样做 - 这是Windows的默认行为和预期行为，你可能会面临危险。用户确实知道ENTER激活了一个按钮，如果你没有指定一个按钮来接受ENTER，那么当前聚焦的控件就会得到它。



最好的解决方案是让ENTER按下等于按钮 - 这很简单。

在你的表格中，覆盖ProcessCmdKey：

 受保护的 覆盖 功能 ProcessCmdKey（ ByRef  msg 作为消息， ByVal  keyData  As  Keys） As   Boolean  
 如果 keyData = Keys.Enter 然后 
 buttonEquals.PerformClick（）
 返回  True  
 结束 如果 
 
 返回  MyBase  .ProcessCmdKey（msg，keyData）
 结束 功能 

i made (0~9)buttons as i want to click the button (instead of pressing it on keyboard )
ex: i click on btn5 then textbox1.text &="5"
. but when i click on any button then press on enter key (the button will be pressed automatically and that what i do not want )

What I have tried:

i have tried to write on textbox just by click on buttons without using any keys (on keyboard)

解决方案

You really shouldn't do that - it is the default and expected behaviour for windows, and you mess with that at your peril. Users do know that ENTER activates a button, and if you don't specify a button to "accept" the ENTER, the currently focused control gets it.

The best solution would be to make ENTER press the "Equals" button - which is simple to do.
In your form, override ProcessCmdKey:

Protected Overrides Function ProcessCmdKey(ByRef msg As Message, ByVal keyData As Keys) As Boolean
    If keyData = Keys.Enter Then
        buttonEquals.PerformClick()
        Return True
    End If

    Return MyBase.ProcessCmdKey(msg, keyData)
End Function
