I have a tabcontrol with a number of tab pages each of which contains a DataGridView control. I populate each DataGirdView form a local SQL Server. The method which does this works fine. The problem I'm having is I want to use the same method to populate each DataGridView control. I created a private member variable called mDataGridView as a DataGridView and use the TabControl SelectedTab property to determine which tab page the user has selected. I then try the following

I then use mDataGridView in my method which retrieves data from the SQL database. Although the compiler dosn't gag at this it doesn't work. Am I right in thinking that mDataGridView references dgvQuoteTemplate?

Two questions:
1) I have a stored procedure that retrieves item information from a SQL Express database. Should I attempt to do the rounding the stored proc or client side in the app?
2) My rounding needs to be custom. I have a figure that goes down to the 4 place meaing x.0000 if the 3rd digit is 4 or more then I would round up to the nearest cent x.00 if it is 3 and below I would round down. I have looked at the math functions in vb.net and I dont see right out the gate how to accomplish this.
So my question is should rounding be done in SQL or client side and if it is client side do any of you have pointers on how to slice and dice this?

GetProcAddress Function Retrieves the address of an exported function or variable from the specified dynamic-link library (DLL).Lets say I have something like this:
Dim moduleHandle As Integer = LoadLibrary("C:myDLL.dll")
Dim methodName As String = ""
GetProcAddress(moduleHandle, methodName)
DLL should be win32 standard dll or .net dll.
How can I run the exported function if I have the address of it through GetProcAddress().If someone could supply some code it would be great.
