You're welcome 
Basically it will work fine. However, it slightly depends on what kind of datasource you have.
If you're connecting to a database server, it will typically works fine as is, but if your datasource is for example a xml file then you have to take care that the directory is correct for database logon in another computer when pointing the file.
If you encounter problems later, open a new thread and we'll try to help.

The need to optimize rises from a bad design.

I need help understanding this procedure.
The project I am working on requires me to printout a form and email it to another department in myh company. The printout is exactly the way I want it, but I am not clear on how to save the PrintDocument to an image. The following link has an example of exactly what I am trying to accomplish, but don't understand how to use "MyObj" to do both.

Any help would be appreciated

What's "MyObj"?? I don't see that anywhere in that code you linked to. I thought the code was pretty self explanitory. What don't you understand about it??

I found that the code I tried to use earlier for my project didn't work for me (link). So, I found code that did what I needed, and that I could understand. This is the code that I used.
<pre>
Option Strict Off
Public Class Form1
Dim pdoc As New Printing.PrintDocument()
Friend WithEvents ppc As New Printing.PreviewPrintController()
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles Button1.Click
pdoc.PrintController = ppc
AddHandler pdoc.PrintPage, AddressOf pdoc_PrintPage
AddHandler pdoc.EndPrint, AddressOf xxx
' This shows nothing on the screen. It ends
' up calling the 'xxx' sub which saves the
' printpage images to files
pdoc.Print()
' This will show a regular print preview
pdoc.PrintController = New Printing.StandardPrintController
Dim ppd As New PrintPreviewDialog
ppd.Document = pdoc
ppd.ShowDialog()
End Sub
Private Sub pdoc_PrintPage(ByVal sender As Object, _
ByVal e As Printing.PrintPageEventArgs)
Static z As Integer = 0
If z = 0 Then
e.Graphics.DrawString("Page pg1", New Font("Arial", 48), _
Brushes.Black, New PointF(100, 100))
z += 1
e.HasMorePages = True
ElseIf z = 1 Then
e.Graphics.DrawString("Page pg2", New Font("Arial", 48), _
Brushes.Black, New PointF(100, 100))
z += 1
e.HasMorePages = True
Else
e.Graphics.DrawString("Page pg3", New Font("Arial", 48), _
Brushes.Black, New PointF(100, 100))
e.HasMorePages = False
z = 0
End If
End Sub
Private Sub xxx(ByVal sender As Object, _
ByVal e As System.Drawing.Printing.PrintEventArgs)
Dim ppi() As Printing.PreviewPageInfo = ppc.GetPreviewPageInfo()
For x As Integer = 0 To ppi.Length - 1
ppi(x).Image.Save("c:\look" & x.ToString & ".jpg")
Next
End Sub
End Class
</pre>
Hope this comes in handy for someone else

I'm writing an application to receive data from a hardware data logger and display it. The concept involves getting the data from a serial port, displaying it in a grid control, graphing it, then saving it in an ASCII delimited format.
So far, I receive the data and I load it directly into a DataGridView. As many of you know, this is extremely slow, especially for tens of thousands of data entries. I've read in a few places that it is more appropriate / efficient / expedient to use a DataGridView by binding it to a source of data. Much of the info I've found on the web relating to this concept deals with databases rather than a port based data stream.
I think my first design flaw was considering the DataGridView the actual data container. Much of this comes from using MSflexgrid in the past.
My questions are...
- Conceptually or architecturally how would you approach this problem?
- In what type of "container" should I receive the data into memory such that it will allow for easy manipulation (grid display, graphing, saving)?
Can anyone point me in the right direction? Thanks in advance.

Any application, even a game, is really just a specialized database management solution. The data you get from the serial port should be cleaned and validated, then put into a data model you construct. Exactly how you build the data model depends on your data and your requirements. Once you have the data model, you can use any controls you need to show it.
The DGV is not an efficient data container. It was designed to bind to various data sources and show and edit the data in that source. You're more worried about how to show and graph the data and not worrying about how you need to manage that data. Once you have the data model built, gridding and graphing it is easy.
Look into the DataSet and DataTable classes as a start. You may even just skip those and create your own classes for records and tables to do this.

Can someone suggest a PDF SDK for VB.NET that can write an image to a pdf, read from pdf and read text on image in pdf?
Preferably open source.
Thanks.

You'll need a couple of libraries. The first two requirements, just about any library, like PDFNet, can handle. Your third requirement, "read text on image", require the use of some OCR library.

Hi
I am relatively new to Reporting in VB.NET. Actually I am asked to retrieve a report which would basically contain some items with extensive calculations which I already constructed for on-screen display, now while creating crystal reports I didnt find the way to refer to that function so that on each retrieval of the database value, report will pass it to a function of VB.NET and then the function will return the value to display in the report i.e.
Private Function CAmt(ByVal Amt as integer) as String
Select Case Amt
Case 1
Return "One"
Case 2
Return "Two"
Case Else
Return amt.tostring
End Select
End Function
Hope you got what I mean to say.
Please help me asap.
