I don't have an example code, but recently figured out how to make a single sub handle the keydown event for multiple text boxes.What I would like to know is if it is simple enough to have the object name that is sending the event instead of "microsoft..text: 54654" (sender.ToString in a debug window) type of return. I don't know how to make use of that.
View 3 RepliesHow to make an event for keydown, but for second press?
Yes, i know how to make event, eg.:
If e.KeyCode = Windows.Forms.Keys.Escape Then
Me.Close()
End If
But i want code for second press. For example...:
First use button space: open form1 Second use button space: open form2
I need to call a text box keydown event from another method. How to I create and event args for this to pass to the method?

View 6 RepliesIs there another way to handle the leave event of multiple textboxes other then coding in each event handler? I may not be using correct terms instead of doing this: (Existing)
Private Sub leveladjstvaltxt_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles leveladjstvaltxt.Leave
If Me.leveladjstvaltxt.Text <> "" Then
Dim levels As Integer = CInt(Me.leveladjstvaltxt.Text)
Me.leveladjstvaltxt.Text = Format(levels, "#,###")
I have 30 TextBoxes all need same formatting , so I was trying to come up with something like this: (trying)
For Each ctrl As Control In Me.Controls
If TypeOf ctrl Is TextBox And ctrl.Text <> "" Then
Dim val As Double = CDbl(ctrl.Text)
CType(ctrl, TextBox).Text = Format(val, "#,###")
End If
I am stuck though and don't know where I would place that code if this is something that is even possible. Only thing I can currently think of is in the leave event which defeats the purpose, I wanted to avoid having to place the code in 30 different textoxes leave event.

I am attempting to fill a form with multiple rows from an access table based off of a parameterized query. My query works fine but I don't want to return one row at a time, I want to return all rows that match my query in multiple text boxes. I know that I can use a datagrid view to accomplish this, but I would prefer the look of a textboxes on a form. I have read through many books and searched the internet forums but think I may just not know what to search for as nothing has worked yet. Can anyone point me in the right direction. So far I have tried setting the text box value to the row().item(), creating a different dataset for each row, and even setting variables for the results of the query to then be passed to the text boxes. Since none of this work, I don't really have any starting code to post. If I could just get a starting point I could work from there, so don't feel the need to code anything for me, just set me in the right direction.
The error it has is that when one of the text boxes is changed the code changes all of them triggering every single function to activate. Is there a simpler solution other then recoding it from the start? also each different Private Sub is identical basically.
