Closing a form without closing the application

[James Rose]

yes you can do this, an example being a Splash Window called during "Sub Main" (old school VB6 etc)

Sub Main

Dim frmSplash as New Splash 'your splash screen form/class

Dim frmMain as New Main

frmSplash.Show

frmMain.Show

End Sub

and then when all the code for frmMain is completed (in form.load) close the splash

Private Sub Main_Load

frmSplash.Close

End Sub

Don't startup on a form? Instead startup on an object that will call forms?

[James Rose]

Correct. Using "Sub Main" as your starting point gives you more options that starting with your main form. For example if you want/need your app to have only one instance of itself you can check for an instance of your application in Sub Main prior to loading any forms. That way if there is another instance you can simply close the new app before loading any forms.

Got it?

Thanks alot for reply, sorry for my late reply.

You began to understand me, the problem was the instance, I have created Definstance for each form.

I managed to close the startup form and loading other form but I faced another problem, see the following example to understand me, and to tell me if i'm doing right.

Example:

Startup form > Form1 (Has Definstance)

Other forms > Form2 (Has Definstance) - Form3 (Has NOT Definstance)

- I opened the app.

- in form1 load

Form2.Definstance.Show()

Application.DoEvents()

Form1.Definstance.Close() ------> Will not work If I used Me.Close()

- The app. works fine until this step, form1 closed and form2 loaded with closing the app.

- in form2 Button_Click

Form3.show()

Application.DoEvents()

Form2.Definstance.Close() ------> Definstance and Me.Close() doesn't work

^ the above code doesn't work this time, Is it because I didn't create a Definstance for form3 or what?

- All the app. closed :(

BTW, I don't want to create Definstance for some reasons, but if the problem depend on it then I will have to.

What is wrong with this code! Thanks for any help :)

[James Rose]

yes, the problem is you are calling Form2 from within Form1, and when you close form1 all references defined and called within that form (aka class) are removed from memory.

This is the reason to use a seperate module, create a proc called "Sub Main" and place your startup code calls within there.

Yea, Thanks alot, now it works fine :)
