Fair enough. You're welcome to offer whatever advice you see fit. Experience tells me that if your advice is easier to follow, people will prefer it, even if it's bad.

Thak you,
I try this as following, but it doen't work
Public Class Form1
Sub New()
' This call is required by the Windows Form Designer.
InitializeComponent()
' Add any initialization after the InitializeComponent() call.
Control.CheckForIllegalCrossThreadCalls = False
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim ind As Integer
Button1.Enabled = False
ProgressBar1.Step = 5000
ProgressBar1.Value = 0
Dim trd As Threading.Thread = New Threading.Thread(AddressOf ThreadDo)
trd.Start()
ListBox1.Items.Clear()
For ind = 0 To 5000
ListBox1.Items.Add(ind)
ListBox1.SelectedIndex = ind
Next
Button1.Enabled = True
End Sub
Private Sub ThreadDo()
ProgressBar1.PerformStep()
If ProgressBar1.Value >= ProgressBar1.Maximum Then
Timer1.Enabled = False
End If
End Sub
End Class

It seems to me that you should do some reading, and perhaps not worry about threads for a while until you've got a greater understanding of more basic things.
When asking a question, you should also define 'doesn't work', that doesn't tell us anything. Does it blow up ? Does it not do what yuo wanted ? Does it do anyting at all ? We don't know. Telling us the line that blows up and the error would also help.
And, what you're doing now is telling the framework not to protect you from yourself. This may work fine for such a simple app, but you'd do better to learn how to use a more powerful thread class ( BackgroundWorker ) and to ensure that your UI access is all in one thread. Then you can write *good* code, instead of just code that compiles.

You right, when I am saying doesn't work, it means in this case that first the listbox fullfilled and then the progressbar get to 100%. I don't see any thread working.
I am sorry my english is not mother tongue, I hope you understand
Thanks

Your code makes no sense at all - your progress bar is running in a different thread to the thing you're tracking progress on. The thread that's adding to the listbox, should be the thread that runs the progress bar, otherwise there's no relationship between the progress made and the state of the bar.
The code also calls a thread, outside of a loop, which will just step the progress bar once. And then it stops a timer, which we can't even see.
Overall, this code shows every sign of you're being well out of your depth with the concepts you are playing with, I'd recommend working through a decent book and trying to learn some basics.

If it is so easy for you to do this why don't you show me the solution like that I will be able to appropriate this easy example to my difficult application?
In my side, I will continue to learn VB.NET in my rythm.
Thank you

the listbox is fullfilled but the progressbar doesn't progress in parallel while the listbox is adding items.
First the listbox add items
second the progressbar =100%
Isn't it?
Thank you

If you would be able to change the macro security level programmatically, what would be the point of having macro security?
Although I am not sure, it seems entirely likely that the Microsoft people have hidden this setting from code, but if you can get to it, you should probably be looking at the properties of the application and not the document, as macro security level is set for the installation.
Now, more importantly, it sounds like you are trying to write a macro virus, otherwise there really is no reason to mess with macro security. If you really need some macro to work for legitimate reasons, you will have to inform the user in some other way that they should change the security level, for the document to be able to do what it is supposed to do, and preferably inform them of what the macro will do.
My advice is free, and you may get what you paid for.

can i add textboxes only in the first cell of datagridview?
I have four rows in the datagriddview.
I am using the following code
Private Sub dg1_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dg1.CellClick
If (e.ColumnIndex = 2) Then
TextBox1.Visible = True
TextBox1.Left = 42
TextBox1.Top = 19 * (Me.dg1.CurrentCell.RowIndex + 1)
TextBox1.Height = dg1.CurrentRow.Cells(0).Size.Height
TextBox1.Width = dg1.CurrentRow.Cells(0).Size.Width
End If
End Sub
as the row index increases , the coordinates flaws increases.

This doesn't place a textbox in the cell. It moves an existing textbox OVER a cell in the datagrid. The offset flaw increases as the textbox moves down because your probably off by one pixel in one side of the multiplication to set the Top value. Instead of 19, try multiplying the row height of the currently selected cell.
Though, why are you hovering a TextBox over a cell in a datagrid anyway?

Can anyone tell me how to add a custom dll control at runtime? I can add the control at runtime but the control is not seen on the form. I can add the control at design time and everything works fine.

me.Controls.Add(yourControl)

This' how the puzzle works. Quite sure everyone knows this game!
I'm a complete noob at this, and have not a slightest clue on how to start building the codes except that:
1. the buttons don't move (am i suppose to put the numbers under the 'text' property of the button?)
2. reseting it will give a new random arrangment
would be interested to know how to replace the numbers with images too..really thanks a million to whoever can help a poor soul here !

One has to ask why you're writing this, if you have no idea how to do it ? If it's homework, you should ask your teacher. If you're just trying to learn, I'd recommend trying something simpler first.

Buttons have an Image property.
