I have an application that frequently modifies the values of certain strings that are attributes of some classes that I use in the application. These strings get modified once every 1-4 minutes during normal software operation. Would the StringBuilder class provide any performance enhancement over a String in this situation? Thanks.

I want to install a specific font with a Windows application. I have added the font to the deployment project, but do not know how to target the font to the C:\Windows\Font folder. Thanks.

Thanks. I am certain that no other user is modifying the record. Could there be a concurrency violation because of some coding error?

Thanks. Actually, that was not the problem. Basically, I wanted to use a DataGridView to display changes to the underlying data source, while using the data bound text box controls for editing purposes. Unfortunately, the way I set it up, the data table was not getting changed by changing the text box values. Still, I have encountered another problem, and that is a concurrency violation. What could be the source of the concurrency violation?

How would I check if I have access?

I've been trying to use the Update method of the OleDbDataAdapter to update a MS Access database, but have not had success. I'm updating a DataTable object through several data bound controls and want to update the database using the values in those bound controls by simply clicking a 'Save' button. The Update OleDbDataAdapter method seemed the most appropriate method to use, but it hasn't worked. I don't get an explicit error, but no changes are made to the source database. Would anyone be able to suggest a reason for this? Thanks.

I'm using the System.Net.Mail client.Send(MailMessage) (Visual Studio 2005) method to send an email confirmation that a new contact has been added to an email distribution list. Before adding the contact to the relevant distribution list database, I want to confirm that the contact's email address is a valid one, so that if, say, the user made a typo when entering the email address, he can know. By using error catching, I can catch and report formatting errors in the email address, but if the format is correct but the address itself is not a valid one, no error is caught. Is there a way to check for successful delivery of an email shortly (almost immediately) after sending it? Thanks.

Is there a way to convert a VB.NET 2005 application to a C#.NET application? Thanks.
