Restrict The Input On An InputBox?

Oct 6, 2009

I am wanting to restrict the input on an InputBox and I am confused about how to do that. I know what to do on a text box to restrict input to numbers, the ".", and the backspace key, but I cannot figure out how to tie the input restrictions to the pop up InputBox. Do InputBox 's have an object name attached to them? Or are they just called InputBox.whatever?

VS 2010 Restrict Input In Text Box?

Apr 17, 2011

im writing a program for counting the cash in a till.i have most of it worked out through research on this site and others. im trying to code a text box that allows the user to enter any amount between 0 and 9999.99. I have everything working except restricting user from entering more than 2 digits after the decimal. I could leave it as is and the currency format that im using will automatically round the input to 2 decimal places but this creates a problem if the user accidentally enters an extra digit and the program rounds up. for example if the user intends to enter "23.34" but accidentally enters "23.345" the program will round up to "$23.35" which will cause a problem in the end calculations.here is the code. if someone could explain what i need and where that would be great.

Private Sub TextBox1_KeyDown(ByVal sender As Object, _
ByVal e As System.Windows.Forms.KeyEventArgs) _
Handles TextBox1.KeyDown

Accept Input For Textbox 1 And Textbox 2?

Jul 14, 2010

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.

Validate Input In A Textbox?

May 4, 2012

how one would go about validating input into a textbox for example:

Lets say the first letter the user enters has to be 'A' and the third letter the user enters has to be any number ranging from 0-9 and the length of their input cannot exceed lets say 10.

This is what I have so far:

If txtOperatorID.TextLength > 10 Then
bErrorOccured = True
sErrorMessage = sErrorMessage & "-No more than 10 chars" & vbCrLf

[Code]....

The coding for the length works(is there a better way to do this)? The coding for the first letter to be A works but then I have no idea how to set validation for any proceeding characters entered. Am i right in thinking I have to find their position somehow in the string if so how?
