I'm making a form where I have two datagridviews. The first dgv is databound to a database. The second dgv is not databound. I want to allow users to drag rows from dgv1 and drop them on dgv2. At the moment I have managed to get it to the point where I can drag from dgv1 to dgv2 but the result is an empty row being added. When I try adding a row without using .Clone I get this error "Row provided already belongs to a DataGridView control."

Catch An Exception And Throw A New Exception Which Wraps The First Exception As An Inner Exception
May 8, 2009It is possible to catch an exception and throw a new exception which wraps the first exception as an inner exception: [URL] Also, if I call a function and it throws a certain error, but I catch it, will the calling code's catch handler execute? If so, and it is of a higher exception type, is this not wrapping the exception? eg I can throw exception ex of type IndexOutOfRange, log it but rethrow, catch a higher up exception and do something, or I can throw a new exception and wrap an inner exception like:

View 3 RepliesDatabase - Exception Occurs When Trying To View DataGridView
Nov 7, 2011I have a very simple table in access. The data is stored from VB.NET using the OLEDB adapter. I have a second form which has just a single DataGridView which was dragged/dropped using VS2010 from the Data Sources window.When trying to view the window the first time no data is shown and the second time an exception occurs and the program closes.
[code]...
In the Immediate window after clicking the Form.ShowDialog() button this message appears: A first chance exception of type 'System.ArgumentException' occurred in System.Data.dll Also, the data does not load into the datagridview. After closing the window and then clicking the same button (Not data has been changed at all) this error appears: Input string was not in a correct format.Couldn't store <07/11/2011 00:55:06> in Time Column. Expected type is Int32.

Building A Connectship (Shipping Service Provided By UPS) Project In VB 10?
May 25, 2012Currently I am building a Connectship (Shipping Service Provided by UPS) project in VB 10. This is my first project in 10, in the past I have always used 2003. We decided to upgrade due to the connect ship API(.dll) wasn't compatible with 2003.
My current problem is as follows:I've built a program that uses ADOBD, some XML httprequests and a little bit of integration with there API they have. I also built it to use .net Framework 4.0. I can run the project just fine on the machine I built it on (XP SP3), but when I go to run it on the other machine, it acts like it runs but just doesn't do nothing. Basically just starts and stops.. The machine is not the same model as mine, but has all the updates (SP3) & the .net 4.0 framework on it. I've also tried installing the software package that comes with Connectship on the machine, this is how the .dll work but it still doesn't bring anything up so I don't think it's that messing it up.I was also wondering, to run VS 10 projects you should at least have SP3 correct or could you use SP1 also in XP?
