I have two textbox controls and I want to accept input for textbox 1 and textbox 2. However, when user enters text into textbox 1 I would like textbox 2 to mirror the same text as it is typed.
I am sure this is a very simple procedure however it is new to me and I am having trouble finding an answer with search engines. Most result are coming back as text that one can read backwards in a mirror which is not what I am looking for.

View 1 RepliesI found this code for making my textbox only accept numbers.
Private Sub TextBox1_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
Dim allowedChars As String = "0123456789"

But... the user can't delete the numbers using the backspace button. How do I do then?
Given a texbox, how can I completely ignore non-digit characters? So if I press "A" or "Z", those characters would never appear in the textbox. I'd like to run a bit of code if the user tries to input digits and if he tries to input non-digits too..

View 6 RepliesI'm fairly new to VB.net (self taught) and was just wondering if someone out there could help me out with some code. I'm not trying to do anything to invovled, just have a textbox that takes numeric value from 1 to 10. I don't want it to take a string or any number above 10. If some types a word or character an error message will appear, telling them to enter a valid number. This is what I have, obviously it's not great as I am having problems.

View 4 RepliesI am looking into data validation as I need a way of setting a textbox to only accept numeric values. I have had a search for this and it doesn't seem as straight forward as I had hoped.
I have found a couple of possible methods, although the sites which I found them where very unclear on how they actually work. I feel strongly that I should know how all of my own programs work >_>
I have no actually got this to work with my program yet. Are there better methods than this?

View 5 RepliesProblem: I wanted data input text boxes that only accept numerical values between 0 and 999. I could check for this during a later 'save' routine, but instead preferred to warn the user at the input stage; so I chose masked textboxes - setting the mask to "000". However these boxes appear and behave differently. They have a row of 3 underscores - which I don't want - and also seem more difficult to hit with the cursor. How can I get Masked TextBoxes to appear and behave exactly as normal ones?
