I am not going to follow a link from someone I do not know. This is no reflection on you, just a rule I have.

Therefore can you describe what you are trying to do?

As Luc has said below, I would simply draw lines to represent the squares and use the Graphics.DrawString() method to 'paint' the numbers in each square.

Again, as Luc has said, you could use a Panel and add the code to do the above to the Paint event handler of the Panel.

Things like that I create by code, and not through Visual Designer.
So get a Panel, and add stuff to its Paint handler for drawing the squares and the numbers.
Decide on a data structure to keep track of the numbers you want marked.

Good luck with our lottery!

How to clear multiple textboxes in a form (using vb.net)

Re: How to clear multiple textboxes in a form (using vb.net)

31-Oct-09 2:59

Hello,

I have 15 textboxes ( textbox1 => textbox15).
After calculating the values, i want to clear them with a single press on a button:

I tried:

For Each ctl As Control In Me.Controls

If TypeOf ctl Is TextBox Then
ctl.Text = ""
End If
Next

but it won't work. What am I doing wrong?
Thanks in advance

Luc

Putting object to an array initializer?

Re: How to clear multiple textboxes in a form (using vb.net)

yes ,

Re: How to clear multiple textboxes in a form (using vb.net)

That doesn't work
See following error:
Error 1 Array initializers are valid only for arrays, but the type of 'arratxt' is 'Object'.

Dim ObjArray() As Object = {TextBox1, TextBox2, TextBox3}
     For i As Integer = 0 To ObjArray.Length - 1
         ObjArray(i).text = ""
     Next

This works;

Dim xTextBox As TextBox = Nothing

For Each xObject As Object In Me.Controls
    If TypeOf xObject Is TextBox Then
        xTextBox = xObject
        xTextBox.Text = ""
    End If
Next

Who doesn't?

I chucked some text boxes and a button on the form, the text boxes had random text in them, the code above is in the button click event.

It works for me! Did you try what i posted?

Yes, i copied into the button click event. But nothing happened
Could it be a problem that my textboxes are also inside a groupbox?

Milad.Biroonvand31-Oct-09 3:58

Re: How to clear multiple textboxes in a form (using vb.net)

31-Oct-09 3:58

Dim ob() As Object = {TextBox1, TextBox2}
For i As Integer = 0 To ob.Length - 1
ob(i).text = ""
Next

Re: How to clear multiple textboxes in a form (using vb.net)

Yes, but you didn't state that in you original problem statement!

change it to;

Dim xTextBox As TextBox = Nothing

       For Each xObject As Object In Me.GroupBox1.Controls
           If TypeOf xObject Is TextBox Then
               xTextBox = xObject
               xTextBox.Text = ""
           End If
       Next
