I'm trying to create an application using an existing form from another application. I deleted the default Form1 from the Solution Explorer, went into the project properties and changed my startup object to the new form. However, when I try to compile the program, I still get the "'Sub Main' was not found" error. Any suggestions? This is starting to drive me crazy. I really don't want to have to copy/paste the old form or re-code it.

Thanks in advance.

Check the project's properties/Common properties/General/Startup object dropdown and make sure it does not refer to "Sub Main", but instead refers to the form you want to start with.

Already done that. What's wierd is that if I recreate form1, then it works just fine.

At the moment, I have a workaround that is acceptable, so now I'm just curious why this would be doing this.

1) Click on "Solution Explorer" tab
2) Right Click on project file icon, in this example "Exercise1"
3) Select "Properties" on the very bottom of pop up menu
4) Select "frmExercise1" as in this example in "start up Object" drop down box and click 'Ok'

Hope that helped

I have already set the new form to the startup object of the project. Same error message.

Same error message, new issue. When I create a new project and run a blank form1, everything works fine. When I do a Copy/Paste from an existing form into Form1 and try to run it, I get the same error message. I'm not adding any code with the exception of collection info for a drop-down box. The solution properties show form1 as the startup object. I can create a button on form1 to run a separate instance of the form I want to create, but that's not the object of the program.

I'm also getting the problem when I create all the controls manually. For whatever reason, it seems that Visual Studio doesn't like the way I've written my code? MSDN says that Main should be created automatically. I don't know if I'm missing another option or what.

Any help? It would greatly appreciated.
