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 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

View 3 RepliesUsing MS Access 2003 I am trying to build a command button in a form which clears the contents of a table column (which are tick boxes) - the idea behind it is this - the database is a contacts database for a club. Every year there is a subscription to be paid, so I want a column to annotate those who have paid (using a tick box). At the end of the year this will be reset - hence the reason for trying to produce a command button that clears out the ticks. What I using is this ....Private Sub Command11_Click()Dim strSQL As StringstrSQL = "UPDATE TBL-Master SET TBL-Master.campaign = '';"DoCmd.RunSQL strSQLEnd Sub(TBL-Master is the table name, campaign is the column name)What I am getting is a runtime error - 3144 -

I am trying to create a simply bouncy ball application in VB net; I am using a timer and the FillEllipse() method to try ad create a new circle at every tick of the timer.
Code:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim Gr As Graphics = Me.CreateGraphics
Gr.FillEllipse(Brushes.Teal, X, Y, W, H)
CollisionDetect()
X = X + X_Dir
Y = Y + Y_Dir
Gr.Dispose()
End Sub
The result? The form continously draws onto itself, without clearing the last circle. This means that you end up with a 'line' of spheres together.
To clarify:
X is well, the X-Coords
Y is Y- Y-Coords
X_Dir is an integer, it is added to every iteration of the loop so the next time the loop iterates, it'll be at a different location;
Y_Dir is the same but for the Y Coords;
CollisionDetect() Is empty. It is yet to be filled, it will handle the collision with the sides of the forms. W, H are width and height, respectively.
