I have a textbox that will be used to type a specific time into. What i want to do is for the textbox to automatically have or produce a colon.
For example when typing in 1245 i want it to automatically appear as 12:45.
I have tried my hand at format() and .ToString but to no avail really.
This is in Visual Basic Express 2008
I'm trying to create a textbox that'll only accept a value in the 24 hour format (i.e. "18:00" or "1800"). I've been reading up on the FormatDateTime Function but I don't know whether thats appropiate...
Also, how do I set a textbox to be fixed with two decimal places? On VB6 I could do this in properties, but I can't find an option ni Visual Basic Express 2008.
The below code allows me to prevent a textbox to only allow numerics, backspace. I would also like to have the textbox to accept ":", but struggling to find the correct way to do this. Could anyone advise? Below code is in the Keypress event.
If Not Char.IsDigit(e.KeyChar) Then
If Not e.KeyChar = vbBack Then
?????????????
End If
End If
