I have numerous textboxes which I use to gather data to be placed into an array. But I want to ensure, before I place them to the array,that there is at least one character (letter or number, no space) in each textbox. Seeing as I have about two dozen, it would seem tedious to write an If...Then statement for each of them. And I cannot use a custom textbox class for this. So how can this be done?
View 3 RepliesI have a couple of textboxes on my form. I'd like to give the user the opportunity to spell-check these textboxes so that they can correct their mistakes and then update the contents of the textbox into the database.
Only thing is, I'm not sure where to begin. I found this thread by Martin Liss, but it errors out for me as it's not .NET.

This is my problem.I have a field set up in MS Access to Boolean YES/NO, this field is populated when the user check a checkbox on a windows form. If the user check a checkbox, the value is written as checked in the data field (MS Access).The problem is when I search for the user information, I need the information from the Data base to populate(return) to the windows form. Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form. When I search for the user info, the check box should check(populate) because the user had checked it on submit.Here is what I have done:

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.
View 2 RepliesI 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 tried this code but it is throwing error.
Private Sub ClearText
Dim ctl As Control
' Clear all the TextBoxes on the form.
For Each ctl In Controls
If TypeOf ctl Is TextArea Then ctl.Text = ""
Next
End Sub
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?

MsgBox("TextBox1 is empty. Please enter something", msgboxstyle.okonly)
Textbox1.Focus()
