Tom,
I find its "Better" to have each type have its own file. Naming each file
for what it contains. As its then immediately obvious what's in the file
by
looking at the file name. Plus you avoid this warning message.

So if you have 3 types (classes):
| CMailMessage
| EmailPoller (the offending Class)
| Project Installer.

You would have 3 files:|
| EmailPoller.vb
| ProjectInstaller.vb (which is created automatically).
CMailMessage.vb


As the message implies, the "designers" in VS expect the class to be first
type in a file... The Windows Service has a designer as it (EmailPoller)
inherits from ServiceBase which inherits from Component. Component has a
designer associated with it.

But why does it work OK in 2002 but not in 2003?

Tom

|I have a problem with a VS 2003 project.
|
| This project was designed and works fine in VS 2003.
|
| But trying to open the project I get the following error.
| ************************************************************
| The class EmailPoller can be designed, but is not the first class in the
| file. Visual Studio requires that designers use the first class in the
| file. Move the class code so that it is the first class in the file and
try
| loading the designer again.
| **************************************************************
|
| Not sure why this is a problem. This is a Windows Service I am creating
| with 3 Classes:
|
| CMailMessage
| EmailPoller (the offending Class)
| Project Installer.
|
| There are 2 files:
|
| EmailPoller.vb
| ProjectInstaller.vb (which is created automatically).
|
| In the following code, do I just move the "Class CmailMessage" code to
the
| bottom of the source file?
|
| If that is the case, why?
|
| I didn't have to do that in VS 2002.
