View 1 RepliesRegex - .NET: Manipulating TextBox Input: Dash Every 5 Characters And Removing Special Characters?
Dec 21, 2011Essentially 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, 2011I 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

Feb 17, 2011I 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.

View 3 RepliesAllowing Certain Types Of Characters For A Textbox?
Jun 25, 2010I am creating a converter program (lengths, weights and such), basically just for the learning process because I still find myself very new to this.Well it's like this, I have a textbox where the user is supposed to write the value of the unit he/she wants to convert. As we all know there is a possibility to write in many weird strings which the program later on result in a big error. I recently managed to get rid of dots, because the program couldn't convert if there were a dot among the numbers "." (commas "," works great!). And now there are other types of errors I need to get fixed. I will make a short numeric list.
1. I wonder if it's possible to make dots "." to mean the same thing as a comma ",".
2. I also wonder if i could disable letters a-z or like -#@%&]?! and so on, i just want the basic 0-9 with a coma or dot.
3. I tried to make a Msgbox that tells the user when he/she has done an overflow, a number to big for the program to handle, for example [Observe the code is also trying to prevent the user from writing a minus "-":
(textbox1_textchanged)
If TextBox1.Text.Contains("-") Then
TextBox1.Text = TextBox1.Text.Replace("-", "")
[code]....
The minus thingy works great, but the 9999999... code, it always creates problems so I have commented it out for now until I know how to handle it.
4. Even though I got rid of the dot "." problem, the user is still able to write more then one comma, and I also want to get rid of that. The code I use right now for the "disable dot problem" is:
(textbox1_keypress)
If e.KeyChar = "," Then
If TextBox1.Text.IndexOf(",") > -1 Then
