I'm trying to make a program that splits the data from one textbox into three.
[Code]...
The user inputs data into textbox 1. he enters "X:Y:Z". He then hits the sole button and it organizes it so that textbox 2 now contains "X", textbox 3 now contains "Y", and textbox f now contains "Z". I'm completely lost on how to parse the data.
I'm working on a query where I only want to use the 8 first characters entered in to the textbox. Is there some attribute to textbox that allows me to do this?
View 4 RepliesEssentially 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.

My program paste lots of stuff to a text box. Is it possible to replace every character that is not a number or a point to nothing? It may get lots of weird character there so is here way to replace them to �� and keeping numbers?
I know how to TextBox1.Text = TextBox1.Text.Replace("%", "") But its too many simbols to list, Can it be done easier?
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

Now I am trying display the result in 3 different columns of my listview and to split them into 3 parts. From my code above, what I am getting is A, B:C, and C in my columns instead of A, B, and C.

P.S. This was a VB6 command line app that I just converted to VB.net & the behaviour only occurs in the VB.net version. It's being called in many places at the moment, so don't really want to have to manually go through all calls & add double quotes around the whole argument.
Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?

Lst.DataSource = ds
Lst.DisplayMember = "tblStudent.FirstName"
Lst.ValueMember = "tblStudent.StudentID"

View 1 RepliesI 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.

If e.KeyChar = Chr(81) Then '81 for Letter Q

View 3 RepliesI 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
