Runtime Added Textbox Not Accepting User Input
Dec 23, 2009
I have a form, with lables and textboxes added at runtime. The labels and textboxes are added properly on form load and display as expected. The form allows tabing into each of the textboxes, but the textbox does not allow user input.
Is this a problem with the way I show the form to the user? >> this particular form is called (frmname.show) from a different form -- If I test this form directly, without being called from a different form, it allows user input in the textboxes. Is it because of the properties I used to create the textbox? >> properties used were - .name, .size, .location, .tag

My app has text boxes to accept input from user to questions shown on labels. When the user input is valid, a literal is added to a string incorporating the user input. If the user doesn't input anything or if user inputs "no" or "None" I want the literal and the user input to not add to my string. Make any sense? See my code below:

If my Category and Forum selection is incorrect I am sorry and feel free to move it. I'd like to have the users input in the message box that will show. For example: There is a textbox and the user puts in their name as Bob. Then the message box would be: What my main goal is, is being able to include the users input they type inside the textbox inside the message box.

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 ?

I am using VS2005 version of VB.Net programmer. I wanted to use the user input but most people tell me to use console...but I cannot use this function since my version is different, it will not show any results. I found that using mask textbox can use to read the user input but I don't know how the code can be written. I want user to input two number such as 1.345 and 2.355 and use this number for addition and give the answer. I not sure how I write the code for mask textbox to be read once user input the numbers.

Preferably without turning the "Enabled" property to false, because I still need to output text from it.
I made a custom control in which there is a textbox but I want it used only as an output control, for showing text and stuff. Problem is that as soon as my form opens up the focus is turned to the textbox and I cannot catch my keyboard events on the form anymore(since the other controls are pictureboxes). I need a way to make this box "unclickable" or any way in which it is impossible to attribute the focus.[url]...

I'm trying to make a program where user can input data from a textbox into an array and when the user hit the enter key, it compare it to a data grab from a text file. Here is my code so far:
Private Sub TextBox_KeyDown(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox.TextChanged
Dim input As String
[Code]....
I got the part where the program can graph data from text file and put it into an array called "varia3". The part I could not get is allowing user to enter data into the textbox. When I run the program, the sec I try to enter a letter or number into the textbox the program ended.

I have built an addin for outlook that has a usercontrol shimmed into the interface. Everything works wonderfully EXCEPT for one textbox on one subpanel of the control. I have tried everything I can think of, but have not been able to resolve the issue:
The textbox *(A regular System.Windows.Forms.Textbox) functions as you would expect in any application with one exception. It will NOT accept the backspace key. So much so that the KeyDown, KeyPress, KeyUp events will not even fire when I press the backspace key. There does not seem to be any parameter suppressing it, and the control has focus. What is even stranger is that it works completely fine if you hold down the shift key while pressing the backspace key.

Private Sub TrackBar1_ValueChanged(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles Trackbar.ValueChanged
txtYears.Text = Trackbar.Value
End Sub
This is the code for the trackbar. At the moment as the user moves the trackbar it inserts the value into the textbox. I want this to work in reverse also. user inputs value into text box, trackbar moves.
I know it is possible as my professors program does this.

I'm using ASP.net 4.0 VB,I am using a session variable to add a user entered code into the url of each page. I can get the code to show up at the end of the page's URL that my textbox is on, but what do I add to every page to make sure that the session stays at the end of every URL that person visits during their session? This is the code from the page that the user enters their user code.
Protected Sub IBTextBoxButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles IBTextBoxButton.Click
Session("IB") = IBTextBox.Text
Dim IB As String = Session("IB")
End Sub
[code]....
This is what I have in the page load of one of the other pages. What else do I add to make sure that variable is added to the URL of that page?
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim IB As String
IB = Session("IB")
End Sub

I am trying to develop a simple math calculator that will allow the user to input the right-hand-side (RHS) of an equation into a textbox on the application and have the application evaluate the expression for a given value of x, which is also input
into the application by the user via another textbox.For example, if the user wants to evaluate the following expression,
y = 3 + 4*x + 5*x^2
then they would input into the textbox the RHS of the equation
3 + 4*x + 5*x^2
and then enter a value of x into the another textbox and click on the calculate button.I tried this:
answer = EquationTextBox.Text
but it doesn't work.

How do you refer to controls that are added at runtime e.g. I can add a combobox and a handler, but trying to reference the controls name in code gives an 'not defined', error so in my example, the control is visible, but I cant populate the combo box or use it in anyway.
