According to your profile am a beginner in programming, I suggest taking on a simpler project rather than trying to write a POS program for a pharmacy that you are using VB.NET/Oracle and have no idea where to start.

Paul, i have started the project already. I only said I am a beginner in programming because I am still in school and will graduate next week. I have designed my forms, I have a Gridview of stock where products are selected and added to a Listview as sales cart. Upon doing so, the subtotal Label should be updated with the product of the Cost and Quantity and Grand Total Labels should also be updated with the a final calculation plus tax. I have a problem here. I have only been able to add/remove item from the Sales Cart(ListView)

What is the code you are using to update? Can't really help much without knowing more about the schema or architecture you have in place.

Not the whole thing, just the suspect trouble spot in the code 
I would single step through everything in the debugger. Also, use the code block tag at the bottom to make it easier to read.

I'm converting a VB6 app that uses the MS COMM control that sends data to various types of printers. I'm now trying to remove the VB MSComm control references and instead use the System.IO.SerialPort class instead.
I need help with the following code block:
strInString = objComm.Input
objComm.InputLen = 0
sngCheckTime = Timer + 2
Do
DoEvents
If sngCheckTime < Timer Then
CheckPrinterStatus = 2
Exit Function
End If
Loop Until objComm.InBufferCount > 0
Is SerialPort.ReadLine the equiv of objComm.Input?
What should this be changed to? Loop Until objComm.InBufferCount > 0
Thanks for anyone who can shed light on this.

Hi All
I wonder if someone could help me with the following;
Our ogranisation would like to have access to a list of the QBDG's in our Active Directory, and then select a group to get a list of the members of the QBDG's via web pages (delivered by web project in VB 2005).
Within Active Directory, the structure is set up as follows;
company.com
- Business Unit
- Computers
- Groups
- Printers
- Users
- Business Unit
- Computers
- Groups
- Printers
- Users
- Business Unit
- Computers
- Groups
- Printers
- Users
.... and so on
The QBDG's therefore are in a number of different folders. I've tried various LDAP queries, but haven't got this at all, lol.
Please could someone help;
1) Obtain a list of ALL QBDG's based on the above structure
2) Obtain a list of Users of one of the groups once selected
Thanks for looking at my problem

Check to see if the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\MSSQLServer\CurrentVersion exists. If it exists, then as expected it contains the version number of the installed SQL Server.
