closing forms issue

[cpopham]

I have a multi form program. I can open the new forms with no problems. But I want to close the current form when the new form opens. When I use me.close(), it closes everything. I do not need to keep the form open and just hide it, I want to release the resources and just close that form. I have searched and still have not found a good way of doing this. Anyone know how?

 

Thanks, Chester

If you close the main form for the application you effectively terminate the windows message loop. You need to tell .Net that another form should process messages and keep the application running.

 

i.e.

'In the current main form

dim f as new form1()
f.show
application.run(f)
me.close();

Okay thanks...

Okay I tried it and it gives me the following error:

 

It is invalid to start a second message loop on a single thread. Use Application.RunDialog or Form.ShowDialog instead.

 

What would happen if I used subMain to declare my form abojects as public?

 

Coul I then close them when needed without affecting other forms or what is wrong with that code. I put in exactly how you described.

I have a multi form program.

Why not use a MDI-form and have your forms as MDI-childs?

Should work from a sub main without any problems. Also is there any reason why you need to change the main form while the application is running? Could you not just use the other form as a startup object?
