No worries - but this is all straight from the source code that you can download from http://www.utmag.com/wconnect/wc.dll?9,7,10,1453

Note that to use it, you will have to incorporate the FormUtils and PrintImage classes from the source code (probably after converting them to VB - so it's not THAT easy :)

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ' Instantiate our PrintDocument
        Dim pi As PrintImage = New PrintImage()
        ' Get a bitmap of the screen
        pi.Bitmap = FormUtils.FormToBitmap(Me)
        If PreviewPrintScreen = True Then
            ' preview the print
            Dim preview As PrintPreviewDialog = New PrintPreviewDialog()
            preview.Document = pi
            preview.ShowDialog()
        Else
            ' print to the printer
            pi.Print()
        End If
    End Sub

Hi,

 FormUtils and PrintImage classes are in CS and i am very new to .NET programming so i wont be able to convert into vb.net. Any other altrnatives.

Is there any alternative way for me to print my form data grid into my local printer. Do i still need to follow the tedious method which u mentioned above to accomplish this task.

It depends - if you just want to print your data grid, then you could do the following:

Option 1 - use a custom DataGrid that has built in print functionality - you can download the source from:
    http://www.codeproject.com/vb/net/datagridex.asp
    or
    http://rustemsoft.com/print_datagrid.htm

Option 2 - print the contents of your existing DataGrid - download an example from:
    http://www.codeproject.com/vb/net/DataGrid_Printing_Class.asp


The long and short of it is that printing from VB .NET is never (at least from what I've seen/done) just a case of click a button and out it comes.  You always have to do a bit of setup first :(
