Thanks...

What I have tried:

If e.KeyChar = Convert.ToChar(Keys.Back) Then

推荐答案

声明



私人Kbd为新的Microsoft.VisualBasic.Devices.Keyboard







以及你想寄回空间的地方插入这条线





Kbd.SendKeys（Chr（Keys.Back））

declare

Private Kbd as new Microsoft.VisualBasic.Devices.Keyboard



and where you want to send back space insert this line there


Kbd.SendKeys(Chr(Keys.Back))

您可以使用SendKeys.Send（）方法发送退格键和空格键


或者你可以使用PostMessage刺激按键。

告诉你要发送密钥的位置

You can use SendKeys.Send() method to send backspace and space keys

Or else you can use PostMessage to stimulate keypress.
Tell where you want to send the keys
