Limit Textbox To A Range Of Characters

Mar 21, 2011

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.

Limit The User Input To Exactly 5 Characters?

Mar 11, 2011

I have 200 dynamic textboxes.

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

Regex - .NET: Manipulating TextBox Input: Dash Every 5 Characters And Removing Special Characters?

Dec 21, 2011

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.

Replacing Characters In Textbox (including Special Characters)

Aug 5, 2011

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.

If I enter a quote " in textbox1, it has to be replaced with " in textbox2.

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

Getting Rid Of Unwanted Characters In The Textbox?

Feb 17, 2011

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))
