Problem when closing Form containing DataGridView kbalias2-Jan-09 1:37 kbalias 2-Jan-09 1:37  Hi I have a very strange problem. I am using Visual Studio 2005 and C# to develop a Windows application. My database is a MS Access 2003 database. On my Form I have a DataGridView that is bound to a table in the database. There are also a few DataGridViewComboBoxColumns that are bound to different lookup tables in the database. I specify the BindingSources for all of these using the designer. When I run the app the DataGridView is populated as expected. The DataGridViewComboBoxes also work fine and I can change the values. The database is also updated correctly. So everything seemed fine. Then I added a Button control to the form by dragging a Button control from the Toolbox onto the Form. Before I added any further code I ran the app again to check something. This time I encountered a problem. After I clicked the Close button in the Controlbox (Top right on the form) the DataGridView gets cleared of data row by row and when all the rows have been cleared the following message appears: "Index 0 does not have a value.". I just cannot see the relationship between just adding a Button to the form and this error message. I am stumped and any advice will be appreciated. Regards.

Try using the debugger - I know, that might seem too much like being a programmer, but after the first few times, you'll find the debugger to be pretty damn useful.

What baffles me is that I have not made any changes. I have not added new records, or modified records. or deleted any rows. I run the app and immediately closes it and the error comes up.

For saving web pages, work with "WebClient" class. It has got methods to download a file or data from a webpage. Then use regular expressions to see what are the other resources (images,styles etc) used and send separate request for these to download. There should be an article on this here in CP.

My application has a DataGridView, which contains a DataGridViewComboBoxCell. Is there any way to make the combo box drop down its list on the first mouse click? Currently, the first mouse click activates the cell, the second one creates the hosted combo box, and the third click finally drops down the combo box list. I'd like the combo box drop down immediately on one click instead of 3. Thanks and best regards Dominik Too many passwords to remember? Try KeePass Password Safe! Re: One-Click DataGridViewComboBoxCell kbalias2-Jan-09 1:58 kbalias 2-Jan-09 1:58  Hi I am not sure if you can set it for individual cells. If you set the EditMode of the DataGridView itself to EditOnEnter then the comboboxes drop down at the first click. Unless another DataGridViewComboBoxCell was in open position. Then the first click will first close the open one and the second click will open the selected DataGridViewComboBoxCell. All the other cells in the DataGridViewRow will also now be editable as soon as they get focus. Regards.

Kobus debugging BHO Maverickcool2-Jan-09 1:12 Maverickcool 2-Jan-09 1:12  hi i'm having troubles debugging an BHO with IE7 and VS 2008 i'm using the BHO from http://www.codeproject.com/KB/cs/Attach_BHO_with_C_.aspx[^] the application is working fine for me I searched to how to debug BHO. this is what I found: "Set your IE home page set to about:blank . That way you can start up the browser as fast as possible and go where you need to. So, start up the first IE window. Then, from VS.NET use the Attach to Process item in the Debug menu to attach to iexplore.exe. Set breakpoints in your BHO. To break within the constructor, just open a second IE window." I did that but it didnt work for me it's just ignoring my breakpoints do you know otherway to debug? or maybe I'm missing something? thanks About My Macro Program's problem.
