Create a string with values from the drop-down controls; String.Format (http://msdn.microsoft.com/en-us/library/system.string.format.aspx) is useful.

Have a look in the System.Net.Mail namespace (http://msdn.microsoft.com/en-us/library/system.net.mail.aspx) in the .NET Framework class library. It provides types you can use to create and send SMTP...

A more detailed description of the problem than "still no luck" would help... is it the same exception or a different one? Exception message and stack trace are both useful. Also, what version...

It's not quite the same; Access is a file-based database system, where MySQL is server-based, so you'll need some sort of open connection to the server to do anything useful.



I don't have a...

To clarify, the .NET Framework doesn't provide automatic handling of multiple key presses. You can still handle them yourself.



This is what's keeping your code from working right--when you...

Simple, yes... but not something I'd allow into production code. See these (http://odetocode.com/Blogs/scott/archive/2004/08/20/401.aspx) links...

Could you post the code you're using to track key up/down status? That would help us find what's going wrong.

If your table has either of those, you may be able to get away with simply adding the...

You can't update the database using OleDbDataReader or any other DbDataReader subclass. They provide forward-only, read-only access to data. You need something else.

There's more than one way to...

Looks like you're not generating the update command. It isn't actually created until you call SqlCommandBuilder.GetUpdateCommand()...

You can't link directly to a COM library; you have to link to a .NET interop library. The VS IDE secretly generates this library for you when you add a COM project reference. Since you're using the...

I don't have any code samples handy, but if you'd like to create your files the Cowboy Way, try this introduction to the Microsoft PCM WAVE file format...
