How to disable pasting special characters in text box?

[PrateekArora]

Hi guys...

I am using a text box in vb6 application and I have applied validations on it such that it will only accept Numeric data through keyboard.
But the problem is when I try to paste some special characters in it through Mouse Right Click, it gets pasted from clip board.
It happens because I have applied validations on Keypress event.
Let me tell u that CTRL+V (paste through keyboard is also disabled).
Now what I want is either I should trap the Mouse right click event and check if "Paste" option is selected, if it is true then I can use "isnumeric(Clipboard.GetText())" and read data from clipboard and prompt a message that non numeric data present on clip board.
If button = vbRightclick then

thnx dude I tried same but I need to enter numeric data through keyboard, if we will lock text box it will create problem.
what I thought is to trap the default menu editor and check if the menu item selected is "Paste", if true then we can check data on clipboard if it is numeric then proceed else show msg of invalid data on clip board.
In this implementation I m having problem that I m not able to trap default menu editor and the click of "Paste " option.
can u suggest anything in this respect...

You could try a simple brute-force approach. In the Change event, just go through the .Text property and remove any non-numeric characters.

Private Sub Text1_KeyPress(KeyAscii As Integer)
    CheckCopyPaste Text1, KeyAscii
End Sub
 
Private Sub Text1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
    CheckCopyPaste Text1, Button
End Sub
 
Public Sub CheckCopyPaste(txtbox As Object, KeyCode As Integer)

While we're on the subject, what about the Masked Edit control?
