Application not closing

[SBM]

I am writing a desktop application in vb6, when I close the application it still show in the task manager

 

[TipGiver]

Is it a single form your app or it has other forms loaded. (not mdi children)?
How do you close it?

Provide first some info/

 

[SBM]

The application has an MDI form and all other forms are set to MDIChild = true

I close the MDI form with Unload ME

 

[LazyMe]

You may have classes/controls that do not unload properly and therefore keeping your form from being able to actually unload. In other words; you have a leak......

What does the app do? Are there any COM objects?

Are there any loops using DoEvents that may be infinite?

If possible, log the creation and destruction of forms/classes to a file. Once you think the program should be done check the log for forms or classes that are not being released.

As a last resort, just put End into the sub that ends your application.

END should never be used in a VB app. It is like getting out of a car while it is still moving. Sure, you'll stop, but whatever else that's moving will keep moving. Objects that have been created (particularly instances of OFFICE) will remain running until you kill them, or reboot.
This could use up all your memory and crash your system.

>As a last resort
Example: the program has to be finished now to be shown to the boss and the fact that the program is not closing is the one big obvious problem he/she should not see. 2 hours after the presentation, when the adrenaline is settling down, you look at the code, destroy all the objects and everyone lives happily ever after =>As a last resort.

be sure to close all objects declared on each forms of your project... eg. opened recordsets... because even if you've unloaded your form, some of the objects you've declared within it will still remain unreleased...

see example below...


dim mRS as new adodb.recordset
.
.
.
Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
On Error Resume Next
mRS.close
Set mRS = Nothing
err.clear
End Sub
