View 3 RepliesI have a reset button created in my VB form, but don't know how to code it so that it will accomplish what I want. I want it to clear the form's text boxes so that new input can be entered. I could just code an end statement but this closes the form, and I want to keep it open to continue working with it.
View 6 RepliesThe program I am making requires the user to select what units he will be using. But it has to be able to convert his entered units and display them in the text boxes at all times during run-time. It works fine the first time the user switches units, but the second time the units are switched all the values in the text boxes go to 0... Ok Button

the project here is to take the three amounts from three text boxes entered by the user and return a string in a label telling the user if the triangle is either a right triangle, equilateral triangle, or neither after clicking a button. The code I have must use a new Class named Triangle. No matter what is entered in the text boxes, the label always returns "You created a right triangle!"

I have declared an array of text boxes created dynamically at run time. The textboxes are assigned some values by user. The text boxes are located in a Form so that once the user fills in the info and clicks the "ok" button, these values are passed at the back end and the form dissappears. However the user can bring back the form again by clicking another button.
The problem is that once the form reappears, the information previously provided in the form remains. Even the user clears the text boxes to provide new value, the text boxes at code behind do not receive these values.
I am using VB.NET vb 2008 . I am trying to create text boxes dynammically and remove them here is the code i have written so far
Private Sub setTextBox()
Dim num As Integer
Dim pos As Integer

I am able to create the textboxes but only a few of them are removed. by using For Each ctrl In Panel1.Controls it doesn't retrieve all the controls and some ae duplicated as well.
My problem is after I created 5 rows of text boxes, I want to add random numbers to all of the text boxes in one time when I click the button.Here are my coding to create text box dynamically:
Private Sub btnAdd5Row_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddFiveRow.Click
For Me.count = count To 5

ive got code like the code below that creates textboxes dynamically. I want to be able to click a button and delete all of these textboxes i make, however im not sure how to do this. When i tell the program to remove the TBIndex control it does not do anything. The only way i get it to work is if i put the command in the same sub as this code. This code runs in a loop by the way.
So if the loop runs one time and creates the TBIndex control and i have a line of code right after to remove the textbox, then it does not show up on my form. But if i put the command in to remove the textboxes somewhere else and run the code the loop runs abunch of times and creates all teh textboxes and the loop is complete, then the remove control part is called and nothing happens. I just need a way to clear all the textboxes off my form with like a button. I also tried painting over the textboxes with a big grey rectangle but that dindt work.
TBIndex.Width = 54
TBIndex.Height = 20
TBIndex.Visible = True

I find myself copying single files to multiple different machines, so would like to create something to help.I would like a numericupdown, which dynamically adds text boxes (which will be destination file paths). I will obviously need it to remove them too when I decrease the number.
View 6 RepliesWith the following example of code, whenever the user clicks a menu item it will load up a new form. This form will then read from a database, and create text boxes throughout.
Private Sub allowances_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If mainMenu.currentSlic.ToString = "0" Then

View 1 RepliesI have created a program and would now like to stop users from entering incorrect values/Text inside specific textboxes. For example i would only like text to be entered when a customer name is to be inputted and if a numerical key is pressed a message box will appear saying "sorry letters only" or something in that line. Also waould like it the other way round when trying to enter text within a number only text box.[code]...

I am trying to follow the book 'Sams teach yourself VB 2008'. It was going well until the end of hour 4. For exercise 1 I have created the form with a button and two text boxes, but cannot work out the code I need to move text between the two boxes. The Object Browser does not seem to help - am I reading it wrong?

View 14 RepliesI have written some code to get the data from a number of text boxes all named in the style txb_[column name]
I want to write this data to a datatable.
The text boxes were initially filled using a row 'aIndex' from the datatable, then the user can edit the data.
When this code runs, the text boxes all revert to their initial values, regardless of any changes made to their contents during runtime.[code]...
Im attempting to loop through all the text boxes inside of a group box, and add the text into a list box to later be written to a text file. Here is the code I am using.
Dim cControl As Control
Dim FILE_NAME As String = "Tester.efw"
Dim Group As GroupBox

Now instead of locating only the text boxes, apparently it is still trying to identify the labels as text boxes, because I am getting this error:Unable to cast object of type 'System.Windows.Forms.Label' to type 'System.Windows.Forms.GroupBox'.
I'm looking for a library for Autocomplete support in text controls which remembers all previous entries of the user and provide auto-complete support for it.For example for "recent files" I use [URL] and it works great. Do you know something like that for this purpose?
UPDATE : This is a .NET Winforms application and I'm using normal Text Control.
I have 20+ text boxes that are all named like:
TxtCustom1
TxtCustom2
TxtCustom3

View 3 RepliesForm1 has 2 public string variables defined and initialized to "" (an empty string).Form2 has 2 text boxes and a button. When the button is clicked the public variables on Form1 get set to the values in the text boxes.This works fine.I recently had to add a module to my project so that I could use Main as the startup item. Ever since doing that the above no longer works.The variables never get set to the values in the text boxes. They just stay empty.My Main code is simply this for now:
Dim f As New Form1
Application.Run(f)
Public Class Form1
Private tb = New System.Windows.Forms.TextBox
Dim posx As Integer = 0
