I'm using C# winForms...For some reason Application.Run() can't not find MainForm code! I'm not getting any build errors and Visual Studio is recognizing my MainForm code. I have no idea what's going on here. The exception is: FileNotFoundException

OK, but which file is not found!

d.allen101 9-Feb-13 10:34am

my form

Is "my form" located in the startup assembly, or somewhere else. I was hoping that you would post the exception text.

Here's the expection - The specified module could not be found. (Exception from HRESULT: 0x8007007E)

And the "specified module" is the assembly containing the entry point or a different one? If it's not the entry assembly is it present in the output directory.

the entry point is "static void Main()" within static void Main() there is a static method call "Application.Run(new Form1())". Application.Run(new Form()) can't not find "Form1".

Bascially, it's telling you that it can't find a class in your project called Form1. Did you rename the file and the class containing Form1 at some point?

d.allen101 9-Feb-13 12:35pm

No I didn't. Do you know how to get the path that the Sytem.Windows.Forms.Application uses to load Form objects passed to it's Run() method? I was thinking then I'd be able to check the path it's using and make sure my Form1 class is in there

Dave Kreskowiak 9-Feb-13 14:22pm

There is no path. Application.Run does NOT load a file from disk.

You pass it an instance of a Form class and even creating that instance, there is still no file to load.

yeah that's where it's crashing at! example:
pre
static class Progrm
{
static void Main()
{
Application.Run(new Form1()); //this where the expect is thrown
}
}
pre

I even tried adding try catch block but as soon as Application.Run() fails throws an exception (FileNotFound)and my catch block never gets hit.

Thomas Daniels 9-Feb-13 10:38am

I think the problem isn't Application.Run, but that the error is thrown in a method in your MainForm.

It's probably failing before that. My first thought is that maybe it can't find a config file or something.

Donald,

It leads nowhere. You are just wasting time. And this discussion is not very useful, because we don't have your project, and even if we had…

Stop doing what you are doing and start working with Revision Control system. Next time, if you screw up something, you will always be able to retrace your steps.

Please see this discussion: Revision control systems, which to choose from?[^].
