Anyways. I am working on a program/game.
Okay so. I have a textbox. and a button. I made the button disabled.
What I want to happen. I want the user to enter exactly 4 characters. Once this has been done. I want the button to becomed enabled.
This is what I want.
If
textbox1.text = (exactly 4 characters) then
Button1.enabled = true
How can I make it so that when a radio button is selected, button1 is enabled?

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.
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

I have a combo box with four option and two textboxes (on forms load the first textbox is enabled and the second is not). When I click on a spesific option from the combo box I want to make the second textbox enabled.
View 1 RepliesI'm trying to allow scrolling in a Multiline-TextBox even if the TextBox is set to
textbox.Enabled = False
This is not possible, as the Scrollbar is disabled with the Enabled-Command, too.The default solution here is to set
textbox.ReadOnly = True
textbox.Enabled = True
but this doesn't really do the trick for me. With ReadOnly I can still select the text of a TextBox as well as place the cursor inside of it. But as I have normal (non Multiline-TextBoxes) and other controls on the same form I don't want that to happen. I want to have exactly the same behavior as all the other disabled TextBoxes.
For everything else, like mimic the color of a disabled textbox and so on, there is a legitimate workaround with the ReadOnly-Property, but I coudn't find any for selecting text and placing the cursor.
UPDATE:I tried to use WIN32 API but it didn't work as expected:
Imports System.Windows.Forms
Imports System.Runtime.InteropServices
Public Class TestTextBox

View 2 RepliesAs i'm learning more and more about developing ive just got my head around creating classes and modules, i started wondering about something to do with configuration of applications where deployment is in a more diverse environment say in a company where different branches dont need access to all parts of a program, so i thought id throw the question out there in a basic sense and get some feedback. so i can go off and do some more reading and learning.
So the scenario in my head is like this.
So we have for arguments sake FrmConfig which is the master configuration form, then we have FrmMain which is the root menu our application general user interfaces with. So here based on what options are checked as enabled in FrmConfig effects what controls (like buttons/menu options) are enabled in FrmMain.
This is very, very simple question, I even posted on another forum, but apparently I didn't get the right answer.

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.
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))

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

View 2 RepliesI 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.
