I want to limit the Textbox to a range of characters in VB. For example, I want the user to enter strings from 5-7 characters. I know how to limit the Textbox to a certain number of characters by MaxLength but that will give him the option of writing just 3 or 4 characters which I don't want to allow that from happening.
I am trying to limit the user input to exactly 5 characters ( not more, not less ), and numeric only.
I have been trying this :
Private Function txtValid() Dim str As String For Each txt As TextBox In Panel1.Controls
[Code]....
But it always shows the last messagebox. Not all 200 textboxes will be filled in, so I suspect that it may have something to do with that, but I just need to stop the user from entering alphabetical characters, and the entered field must have a length of 5
Essentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.
I have two textboxes. I type in one of them and the text gets copied in real time into another textbox. There is one catch. I need to replace specific character with something else.

I started with something like the below code, but obviously this does not work (tried different stuff - this is for demonstration only). In the example below 'a' represents " , and 'b' represents "
Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp TextBox2.Text = TextBox1.Text
I am trying to auto tab to the next text box after my limit of characters has been reached in a text box. Visual Basic 2010 Can this be set in the properties? I have 7 boxes, each allowed to hold only one character.

I am a new VB programmer and am using TextBox in VB2008. Here are the problems I experienced in TextBox -

2, Can anybody tell me how to set number of characters are allowed to be typed in TextBox?
3, Can anybody tell me how to implement the feature that only numbers are allowed to be typed? In case letters are typed, how to tell user to re-type?

I am trying to show the square root of the number entered in the textbox. when the user presses Q (Uppercase), the square Root should be shown (in the textbox). I did manage to get the sqaure root, but the problem is that when I press Q the Letter Q is also typed in. For example, if I enter 25 in the textbox and press Q then I get Q5 as the result. Is there any work around to this problem ? Below is the code that I have used.
Private Sub Textbox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress If e.KeyChar = Chr(81) Then '81 for Letter Q Dim root As Double = Math.Sqrt(Val(TextBox1.Text))
I have a a multiline textbox, I want to take each and every character that the user enters and on a button press it replaces them with a set of characters, like:
i with x75d
or:

Dim input() As String Dim txt as String Private Sub Encode_Click(ByVal sender As System.Object, ByVal e As
