Multi Form on Windows form application

[kief12]

I am trying to make an application that has a starting form and then if you click on a button it opens and another form. I am using VC++ and i create 2 new forms in it and used this to start the other form.

Application::Run(gcnew w_Name());

It complies fine but gives me this run time error

An unhandled exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll

Additional information: Starting a second message loop on a single thread is not a valid operation. Use Form.ShowDialog instead.

[weaknessforcats]

Application::Ru n() starts a Windows program message loop.

Only one of these loops is allowed per application. You can start a second application as a separate process but you can't start a process within a process.

If you want a second process then call CreateProcess() from your first application. Otherwise, you will just create windows and forms using somerthing other than Application::Ru n().
