Hi all,
I′m a real SQL rookie and after two days of intensive research and reading of dozens of articles and web pages a bit confused about all that knowledge concerning database technology ... and I only want to do something very easy ...
Now, my question is, how can I produce a diagram from that data, that is stored in a table, maybe called "DiagData1"?
I have installed SQL Server Express 2005 and Visual Basic Express 2005 and did some first steps with it as where shown in an brilliant tutorial that I′ve found on a Microsoft (?) webpage. It shows the complete way building a database and connecting it to a form which was build with Visual Basic. So all what is left is find out how the database tables are connected to a diagram.
thanks′n greets,

Hi all,
after long hours of reading and testing there′s some success now. Taking some lines from the online help I′ve done the following VB-prog that produces lines on the form when the button is pushed.
Now I would like to know how the button can be added by the prog at runtime. When I try it with the lines, that are commented out, I get an error.
Does anybody have the solution?
Thank you and greetings,
VBFan
Public Class Form1
Dim clI As Integer = 0
' Private Button1 As New Button()
'Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' Me.Controls.Add(Button1)
' Button1.Height = 100
' Button1.Text = "Draw Line"
'End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim myPen As New System.Drawing.Pen(System.Drawing.Color.Red)
Dim formGraphics As System.Drawing.Graphics
formGraphics = Me.CreateGraphics()
formGraphics.DrawLine(myPen, 0, 0, 200, 200 + clI)
clI = clI + 10
myPen.Dispose()
formGraphics.Dispose()
End Sub
End Class
