I create a DataSet with 4 tables in it from a mdb file using the Wizard of the VS Express 2008. I have a DataGridView and I display the data of the "Transaction" table. I also have a table with my suppliers called "Suppliers". In "Transaction" table I have a column called "Supplier".
I have enabled the options to add,edit or delete record in the DataSet and to save all the changes back to the mdb file. To provide an easier way for the user to add new records I set "Supplier" columnType in the DataGridView as DataGridViewComboBoxColumn and DisplayMember, DataSource and ValueMember to the "Name" column in the Supplier table so the user can directly select the name name of the supplier without having to type it.
So when I run the program and load the form I get the following error message:
System.ArgumentException: DataGridViewComboBoxCell value is not valid.
Any help would be appreciated....
Thank you

Check the AutoSizeMode property of your DataGridView.
You may have set some column(s) to expand the column width to fit the data. Depending on what data you have there (or actually you don't have  ), you will get that kind of error if the lookup is turned on.

Make sure the different computers have the .NET framework installed and the correct version for your application.
If you make a setup project you can make it detect this and download the framework during install.

Thnks all
But it's very small project..It works fine in other PC's having .NET Framework..
Do i need to add some configuration file so that it works fine everywhere without taking care whether .Net Framework is installed or not..
So sorry for simple question...I just start working in c#..

If the correct version of the framework isn't installed it will not run.
If the other PCs are running Vista and your app requires administrator rights then you'll need to add an application manifest so UAC prompts for it to be allowed. I've mentioned this before somewhere, I'll try and find the link.

I can't find it but it's very simple.
How to prompt for UAC elevation in Vista.
In Solution Explorer, right click your project and select Add|New Item. Select Application Manifest File and click Add.
In the app.manifest file, change the line that reads
<requestedExecutionLevel level="asInvoker" uiAccess="false" />
to
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

I tried dave but it's not working... Now it's not giving any error but showing nothing...
Neverthless thnks..

I think you need to put some try/catch blocks in your app and write any caught exceptions to the event log so you can see what's happening or where it's locking.

Make sure that .Net Framework is installed on each computer where you are deploying your executable. Also, check that there are all the files that are referenced by your program.

Why not make this a one-liner? you.suck = (Programming != Your Passion)

Hi All,
As my subject says all that I have been struggling with the same exception as "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond".
The scenario is I am using socket programming to send some data to the client machine from my server using a web service. I have tested around 50 odd cases in which the same exception is raised in around 10 cases and rest is delivered successfully.
Can anybody help me out with this exception? Exception details are pasted below -
System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
at System.Net.Sockets.Socket.Connect(EndPoint remoteEP)
at System.Net.Sockets.TcpClient.Connect(IPEndPoint remoteEP)
Thanks in Advance....

Possibly a firewall or antivirus blocking the required port on the clients or the router blocking that port if they are behind one?

Because you built the installer that way. What are you using to make an MSI ?

OK, I presume it's assuming that you are the author and want a group created. If there are no options presented, you'll need to use a different tool, like Advanced Installer.
