Ok. If i'm add 9th new line, it also working well.

        Dim txtBx As TextBox
        Static x As Integer
        Static i As Integer

        txtBx = New TextBox

        txtBx.Location = New Point(10, 10 + x)
        txtBx.Size = New Size(100, 20)
        txtBx.Name = "txt" & i  'New code

        i = i + 1
        x = x + 20

        Me.Controls.Add(txtBx)

But how to assign a value to that text box?

This is button2 click event. (above code is for button1 click event)

txt1.text = "My value 1"
txt2.text = "My value 2"


actually there is no any property for txt1 and txt2. (blue color underline for it)

Still couldn't find a good method for it.

First of all thanks for reply.

Once again I tryed this code

Dim txtBx As TextBox
Static x As Integer

txtBx = New TextBox

txtBx.Location = New Point(10, 10 + x)
txtBx.Size = New Size(100, 20)

x = x + 20

Me.Controls.Add(txtBx)

It is working well. But I dont know How to name (when draging a tool from toolbox, we can go to properties and can be able to ) the dynamically generated textboxes.
for an example if we want to assign a value to a variable we can use this code.

Dim var1 as string
var1 = textbox1.text

But I have no idea how to assign values to variables from dynamically generated textboxes like above code.

Please tell me how to do this.

If you just need to pass variables between forms, you can use this.
Make 2 forms. (form1 and form2)

form1 code

Private Sub Command1_Click()
Dim MyVar As String
MyVar = "My Test String"
Form2.x = MyVar
Form2.Show
End Sub

---------------------------------
form2 code

Public x As String

Private Sub Form_Load()
MsgBox x
End Sub

Ya BBec. I also tried a lot to uninstall HALF INSTALLED instance. (Some instance are showing in Services which can't be able to start the service) The problem is the server is owned to a major company and can't uninstall the SQL server. It should work for 24 hours. Try to find a better answer and if you find a proper solution other than uninstalling the SQL server, please post it this thread. Thank you.

Thanks sela. I'l Try this.
