I am trying to draw textboxes when the user enters the amount of textboxes to be drawn on one form and the textboxes get displayed on the another form. I have found these codes online but it works with inbuilt codes I guess. That is, the number is already hard coded in the form.

I was about to create a program about CPU Scheduling (SJF Nonpreemptive), Now, I want to ask the user to input the no. of processes ,then based from the user's input I would display exact no. of text boxes where the user could enter the value for each process then store it in an array. But I don't know how to code the text box., I'm new to VB.net and I'm used to it's 'drag and drop' nature. I just want to know how the code to output this text boxes. and is it possible to have an array of text boxes?
BtW I'm thinking of using 2 forms here
Form 1 for the USER INPUT OF THE NO. OF PROCESSES
Form 2 for the output of TEXT BOXES
I'am creating a program that will input a number in a textbox for example 5 and display 5 textboxes in form...I have no idea how to do this but here is the code i've done..

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

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'm converting a user generated list box to an array and then generating a user defined number of random strings and placing it in a textbox.The code I have works fine as it will generate the number of random strings the user wants, except sometimes a line is blank at the top of the list but is counted as a string.
View 4 RepliesI want to create a button that calls a preset cmd line like
"CALL binphpphp.exe -S 0.0.0.0:8080 -t bin"

I would like to create a button that clears textboxes and comboboxes when it is clicked. For example when 'btnClear' is clicked then txtDate gets cleared (i.e. txtDate is 22/05/2000 then when btnClear is clicked it has nothing in it)
I have already tried
txtDate = ""
and
txtDate = Nothing
but an error comes up.
I created a listbox using VB.NET. When the user select an item (it is a string format) in the listbox and click on a button, there will be a number beside the string and the number will increment which time the button is clicked. Anyone know how to do it...?Below is the coding I'd done, but I don't know how to do the increment part. Anyone know what coding I need to add?
Dim no As Integer = 0
listBox.Items.Add(listBox.SelectedItem & no)
I was looking for some better way of coding to populate all text boxes and make them visible once a button is clicked. I have a letter like format on a page with labels displaying address, name etc and it was recommended that on this page some of the information should be able to be edited. The idea I had was to keep the labels displaying the information but then when the edit details button is clicked the labels disappear, text boxes will appear and be populated with the same text as the label to allow the user to edit the details.
I seem to repeating lines of code but changing one thing each time on page load
Dim Sname As String = Request.QueryString("Name")
lblStuName.Text = Sname
tbStuName.Text = Sname
tbStuName.visible=false
[Code] .....
On edit button
tbStuName.visible=true
tbAddress.visible = true
etc..
On the save button
sqlStatement = "UPDATE StuTable SET Name = '" & lblStuName.Text & "', Address = '" & lblAddress.Text
My code seems very repetitive in many parts, I was looking for a better coding style to do this.
I want to ask about the VB. NET Array
I want to create an array and Textbox & Button Array consisting of one thousand number and Letter( one thousand )

and
From A - Z
When i press on Button, I want to see one thousand random number Every time the numbers must changed! Except the location 400 and 410 for example i want to see in the location 400 " 7 " for example and in the location 410 "Y" for example
I'm trying to code an 'increase' button to prompt a user to input a rate by which to increase select prices in an array.It should request the increased rate, then request a number from one to five, representing which price in the array to increase.Then, if 'increase' button is selected again and another number from one to five is chosen, then that element should be increased.It's working, but all the numbers in the array are changed. And, when I hit the increase button again, the array is repopulated below the first price increases instead of only replacing the designated price.
'declare 5 element array of prices
Dim prices() As Double = {12.2, 8.5, 12, 50, 2.4}
Dim rateIncrease As Decimal
Dim isConverted As Boolean

i am in need of some help getting my code working correctly like i am needing it to.

I am trying to save new data every time and then I have to edit it or load it. here is a screenshot you might get some idea by looking at this:
First I will input data (in all textboxes) using create button which will be stored then If I want to edit any thing I will input only the part number and press search. the stored data will come up. I will edit it and update it (Load button is update). Now I can save it in txt file and load it using regex but the problem is edit. I can not edit. If i create a database I cannot save 100 parts (or may be more) in one database so it might create too many db files. So is there any other option I can save parts detail then load it and edit it without create so many dbs?
this application I'm writing is for Employee Data. I have 7 texboxes and 1 combo box.With the file menu I have used that function to save info inputed in one texbox. However for this application I need to use btnSave button to save the record.

View 3 RepliesIs there a simple way to save user input from MANY controls (textboxes, comboboxes, etc...) to a text file? When I say 'MANY', I am referring to at least 580 textboxes and several dozen comboboxes.
I may be able to accomplish this using the StreamWriter Class, but doing this individually would take quite a long time. I suppose I could also change all text boxes to richTextBoxes and save to .rtf. It seems like this would be even more time consuming.
Surely there is a simpler way to do this 'globally', perhaps with an added single line of code that points (and saves) to a preset or created text.txt file whenever text is added or changed in a textbox or combobox throughout the program.
I have an existing database that I want to add a number to that the user inputs. So lets say that in the database there is 4 carrots, and the user on the addinventoryform inputs 3 carrots and pushes a button. Now I want that number to be added to the database number so in the database there would now be seven carrots. I am using an oledb connection and cannot figure this out.

What I'm trying to do is make a list of members in a read only textbox getting the data from two textboxes (first and last name) and a 'save' button.
I've made a class named 'Deltaker' (Members in english) to store data and a list 'resultater' (eng: results) using the 'Deltaker' class.
I'm trying to get user input from two textboxes 'tbxFornavn' and 'tbxEtternavn' and I use my class' public function 'Navn' to display it in the textbox 'tbxHistory'.
I've got a sub procedure to add the input to the list and clear the textboxes and enable another reset button.
So for the save button click event I run the sub procedure and I've written a for next loop to display the results from the list. The first name I enter is all good, but with the second name entry both the first and the second name gets listed as well as the first name that is already there. I thought about using the .clear function to clear the list after each input, but I also want to incorporate laptimes in the list and display the best time in a lable at the bottom of the form. Maybe also sort the list, so I need the data in the list to stay intact.
Public Class Form1

I have the following radion button in VB.NET

<asp:ListItem Value="1" >Yes</asp:ListItem>
<asp:ListItem Value="0" >No</asp:ListItem>
</asp:RadioButtonList></td>
I need to figure what button the user clicked on and then set a variable with that value.How would I go about doing this?
There is newer code in a follow up post. I suggest using the code in the later post rather than the code in this one. You can still read this post though. When designing a user interface, one should be conscious of how many individual controls are required to implement the functionality. In some cases an initial design may begin with many buttons or textboxes (for example) but then further review of
the actual required functionality allows for a reduction in the number of unique controls.
But other times, there isn't a better way (which will still make sense to the user of the application) then to have a series of many repeated controls. So in the cases where one can be certain that the best UI implementation for an application will require the use of multiple copies of a given control, then it often becomes necessary to maintain some method of managing all of those controls at various points
throughout the application. Doing so typically requires that one build up some collection of controls which can then be accessed by index in order to work with any given control; but this can lead to a lot of clutter in the code file which handles these control's events. For instance there will be some kind of collection declaration, some recursive routine to find all of the controls of interest, and then any number of event handler methods with long lists of Handles clauses, or additional code loops to wire up the event handling for each control.
Purpose Since most of this functionality could be considered a requirement regardless of the type of control being managed, or its required functionality, it may make sense to wrap all of the control management functionality into a single class. And since our first requirement is a collection of controls, then a base collection class could be the perfect starting point for our control manager. There are a number of existing thread around this topic, with some recent (at the time of this writing) ones being:[URL]..In this, and related, threads I have posted examples of a simple TextBoxManager and ButtonManager control. But again, with so much similar functionality required regardless of the control being managed, it would be technically possible to create a generic ControlManager(Of T As Control) class which can manage any type of control.
[Code]...
So in summary, one can facilitate managing a large number of user interface controls by building a "control manager" class which both encapsulates the list of control instances, and deals with adding and removing defined event handlers for every control it manages. The generic control manager class itself can be inherited and extended into a more specific class on a per-application basis in order to provide more application-specific functionality.

The above code is from a small program I have written. This test is done on about 30 textboxes I am using for the user to enter number.
The following is the sub routine that is called.
Sub ShowError()
MessageBox.Show(BoxName & " must be a number.")
End Sub
Here is what I want to do but it won't work.
BoxName.Select()
This is so I can put the focus on the different boxes that might contain an error.
