Removing All TextBoxes On A Form?
Feb 27, 2010
I'm dynamically creating x number of textboxes on my form. Once I have done this and the user has done some stuff with them they need to be able to remove all of these textboxes to start again. I've written this code to go in a button, but it only gets rid of two of the textboxes at a time rather than them all in one button click (so it takes like 8 button presses to clear all of the textboxes on the form). Can anyone see the problem?
Code:
For Each ControlObj As Windows.Forms.Control In Me.Controls
If TypeOf ControlObj Is Windows.Forms.TextBox = True Then
[code].....

This is my first post here as I am in the process of writing my first vb program. I just recently learned VBA and prior to that I had no programming experience. I decided that my first attempt with VB would be to convert a program that I previously wrote in VBA. It runs in an excel workbook but it doesn't actually use any excel functions so I figured it would be acceptable to convert. I am having an issue with removing controls on a userform. A commandbutton adds a line of about 6 controls. The user can add as many lines as they need to input their data. One of the 6 controls is a delete button that deletes the line of controls next to it. I have created a collection named Cashflows that holds each line of controls and each line of controls is named with a number that indexes the name to the line that it appears on in the form. In VBA I use that number to delete the actual controls from the userform and reposition and rename the remaining lines of controls.
Private Sub Delete_Click()
Commandbutton3sub(CInt(Right(Delete.Name, Len(Delete.Name) - 6)))
End Sub

I'm migrating from VB6 to 2008. I am replacing a text box and a AxUpDown control with a Numeric UpDown. I have added the Numeric Updown before deleting the AxUpDown - to check its working. There are no references in the code to the AxUpDown but when I delete the control and run the application I get the form displayed but all the fields are blank, the form is partly see through and the application hangs. I'm not sure what is going on and don't know where to look.

I have a lot of buttons on a form (144) that need to be removed. All their names begin with "R". So I used this piece of code.
Sub RemoveBookingButtons()
Dim cntrl As Control
[CODE]........................
However whenever I run this sub function, it deletes every other button starting with "R". better code or point out if the flaw is in that piece of code or it is hidden somewhere else in my program?

i have created a splash screen by removing form border and importing an image to the picture box. also i have set a timer for 7 sec after which the splash screen will close itself and will open the MDI form. But after seven second altough the splash screen closes but it also closes the MDI form too. I am not able to figure out the problem.
Form1.vb
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I'm trying to remove a line from a text file that begins with a set value.
The idea would be to paste values into a Windows form, which then finds each line that begins with that value (a 5 digit number) and removes those lines from the file, and then removes the gaps.

I've recently run into an unexplainable issue regarding a windows form application I am working on. I've managed to isolate the issue to a single line of code whereby a single TabPage is removed from a TabControl, leaving no tabs left in the TabControl's collection. What happens next is a bit mystifying: my application proceeds to enter a state in which the main form's Activate event is fired subsequently followed by its Deactivate event. As a result, no matter where I click on the form, the application will activate for a split-second then immediately deactivate itself, thereby causing me to be unable to interact with any other GUI controls on the form. I thought maybe another thread is trying to interact with the deleted tab object, but the tab is created and destroyed on the same main gui thread. Does anyone have any insight that may point me in at least a new direction? Stepping through the debugger to the point in code where the tab is removed does not cause any exception to get thrown, so at first glance there doesn't appear to be any coding issues going on (although I would not be surprised that is actually the case!).

I'm brand new to VB, though I have some experience in C++. I have a 9x9 grid of many textboxes in my form, and I am trying to output the position of each textbox, as well as its contents, to a text file. For example, if the textbox (3,4) contains 5, I would like to output 3 4 5 to a file, and so on for each text box. Also, I really have no way of knowing which textbox is which, they are only called TextBox1, TextBox2, etc.

I created a Fuction in the module in order to clear all textboxes in a form.
The clear button does work but it still displays an error at the bottom saying :
Expression is of type ........., which is not a collection type.

I am trying to write code to clear all textboxes on a form automatically.
I have entered the following code:
For each ctrl as Control in me. controls
If TypeOf ctrl is TextBox then
ctrl.text = ""
end if
Next
The form has various controls on it, including textboxes, buttons, and others. When I run the above code 'ctrl' only seems to find buttons but not textboxes.

I have a form that has a tabcontrol (TabControl1) and within that tab control is another one (TabControl2). I have textboxes on the main form as well as in each of the tabcontrols.
In my savebutton event I have the following code:
If CheckIfDirtyAfterLock = "Just Unlocked" Then
CheckIfDirty(Me.Controls)
Else
[Code]....
What happens is that it records those textboxes that have changed and writes it to addendum.text. The problem is that it is only capturing those textboxes on my main form and none of the textboxes that get changed within TabControl1 or TabControl2.

I'm using VB 2005 and have an Edit - Entry form with Textboxes and several Comboboxes. I populate the Comboboxes with Arraylists as shown below. I populate a datatable with the Employee data from my SQL Server. I assign the BindingSource1.Datasource to my Datatable then add Databindings to the ComboControls. The (Fields.STAFF_MGR_ID.ToString) is from an Enum. When all is complete my textbox fields Bind and move with the MoveNext.. no problem, but the comboboxes display nothing.
Dim Manager2 As New ArrayList
While dr.Read
With Manager2
.Add(New ListContents(dr(1).ToString, CInt(dr(0))))

Actually I am trying to get a function to validate all the textboxes in my form. At the moment, my code look like:
Private Sub Textbox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Textbox1.textchanged
If Textbox1.Text.Length = 0 Then
MsgBox("TextBox1 is empty. Please enter something", msgboxstyle.okonly)
Textbox1.Focus()
Endif
End Sub
I have to write the same line of code for each textbox to check if it is not empty and was thinking of using a function that will be called and check each textbox in my form.

I have 5 text boxes that I need to perform several operations on as a group, named tb1, tb2, tb3, tb4, tb5.for example, if I want to retrieve the text from each one and process it, I believe I can use the text box or control collection and test each textbox to see if it's name starts with tb, check to see if it has text in it, and then process the text.I think I would use something like for each textbox in..... to test the collection but not yet comfortable with collections and this seems like a good place to start learning how to use them.

How do I easily navigate textboxes contained within a form.My form has a lot of textboxes so I don't particularly want to make a KeyDown event for each.I think I need to group the controls and handle it that way somehow with their TabIndex.I'm lost without the control array of VB6 and can't find anything to show me how to do it.

I have a form with many different textboxes on it. The form is used to Edit the data already in a databound table. At design time I set my Databindings.text to the appropriate columns.
During form load I check the values in the bound column for null values. If the column value is null, I set the textbox.text property to a descriptive prompt like "enter telephone #" or enter city. I also use databinding.remove to remove the databinding so that the desriptive prompts don't wind up in the database.
Here is the code I use to remove the databinding.
For Each Panels In Me.Controls
PBox = TryCast(Panels, Panel)
[CODE]...
.Tag2Defaultphase is a custom property I have defined which holds the default descriptive prompt. If the user enter a value into the textbox I then wish to add the bind back so that when I updateall with the tableadapter the value will be transferred back to the appropriate bound column.
Here is my code for that:
Sub perOptionalTBoxValidation(ByRef TBControl As custTextBoxControl, ByRef strDefaultTextPhrase As String, ByRef intMaxChars As Int32, ByRef bsBindingSource As BindingSource, ByRef strColumnName As String)
[CODE]...

I created a form with 2 labels 2 textboxes and a button. Basically it is a login from. When I launch the form it shows the blinking cursor in the 1st textbox(this is ok) but when i try to type nothing happens. Once i click the form(not the textbox-textbox works too but wanted to note it was the form) it works. I have tried doing textbox1.focus(). I have tried doing the form.focus(). Neither were successful. It may have nothing to do with focus but it seems to be that to me.
