Hi, the Windows.Forms.Timer is my prefered timer. The MSDN documentation says it is single-threaded, which may mean you should do all its operations on the same thread (i.e. creation, Start, Stop, etc) as if it were a Control. Since it Ticks on the main or "GUI thread", my advice is to create and control it on that thread too (e.g. in a Form_Load handler, a Button_Click handler, etc.). BTW if this does not help, you may want to show the relevant code. :) Luc Pattyn [Forum Guidelines] [My Articles] Sorry for any delays in replying, I currently don't get e-mail notifications.

tnx Guys. I'm implementing and error generator sub that take error code and message from various exeption handlings and it should raise respective events.

Wow.Great. Tnx for your reply.

Me cannot be used here. It's an abstract concept that refers to the current instance of the class that it shows up in. You have to replace it with something like this: Private Sub Test(ByVal vl1 As Integer, Optional ByVal val2 As Object = Nothing) If val2 Is Nothing Then val2 = Me End If A guide to posting questions on CodeProject[^] Dave Kreskowiak Microsoft MVP Visual Developer - Visual Basic      2006, 2007

I don't think you can have it centered on the TableLayoutPanel.

I was able to add a label to a picturebox and it's transparency worked fine. How are you creating the label. Is it done at runtime or design time. Remember that the location of a control is relative to it's parent. So if the label exists at design time and is located 100 from the left and 200 from the top it will be in that same relative position when you set it's parent to the picturebox. What may be happening is when you set the parent to the picturbox the label is positioned where you can't see it. Try setting it's position to (0,0) and see if it shows up. As proof of concept try creating a new project. Add a label and a picturbox to your form as well as a button. To prove the transparency works give the picturbox an image. Then add this code. Private Sub Button1\_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'Set the parent Label1.Parent = PictureBox1 'Position the label so we can see it Label1.Location = New Point(0, 0) 'Give it a transparent background Label1.BackColor = Color.Transparent End Sub

Excuse me. :D My pic was a png that has an inner gradient. :b

Yes you are right! I made a mistake in adding it to tabcontrol not tab page. Dim myt as new textbox TabControl1.TabPages(0).Controls.Add(myt) is working... Thanks. What a curious mind needs to discover knowledge is noting else than a pin-hole.
