Question about closing a windows form

[wdw]

Hello,

I've got some windows forms, I want to close a form with the Cancel button(alt+c) and then showing the page before the closed page.
now is my problem when i click alt+c my whole application closes, because on all of my forms alt+c is for closing form.
If i click alt+c very carefull i get to the desired page, but when i click to fast my application closes!!!

Does someone have an answer to my question???

Do you mean your want the first form shown to be closed, and a different form shown in its place?

If so your message loop will have to be changed slightly. You'll have to make your startup object Sub Main instead of a form, and write code to run a message loop which doesn't just depend on one form, using Application.Run(). Then, when you need to terminate your app, call Application.Exit() to shut down that message loop.

Couldn't you put some sort of handling like

Dim frmHome as New fclsHome
frmhome.show

in the Form Closed event?

I might be off here, but that seems like it would work.

dejota6, yes it would if he has his message loop set up properly.

By default the startup object is set to one form, and as soon as that form closes your message loop is stopped so your application will quit.

Ok, I believe this thread might be off track a little, but I guess I don't know what a message loop is. Could you explain that real quick. It might be that I just haven't heard it phrased that way.

All Windows programs with a user interface need a message loop that listens for the messages Windows sends to all the windows in your application.
