End App Thru DLL

[SpiderBear6]

Is it possible to end (gracefully would be nice) an application through a dll that was called by that application? I can't use End.

Not quite sure of what you are doing but in each form you should use a sub that does all of the cleanup for you. Most of the time I use Query_Unload to do my cleanup. Then if I have public objects that could be instantiated I have a public sub that takes care of those objects and end my program for me.

So my suggestion for you is to do something similar (this is just an example...
[tt]
Public Sub EndProgram()
Dim F As Form
For Each F In Forms
Unload F 'this will tell the form to unload which in turn will activate the query unload in each form (if it exists)
Next
'clean up public stuff here
End Sub
[/tt]

Also to answer your question I do not belive it would be a good idea to attempt such a thing.

Good Luck

VB5, i think the main question asked here is if it is possible to End an application from within the dll that it is connected to...

Spider...I would look into the raise_events functions of DLL's in order to raise an event in the main app, kinda like when a textbox is clicked "text1_click()" or whatever, and in the event you can run the end or whatever clean up code you may need.

Hope this helps

Spider - remember do dim your dll "withevents"...

Well thank you mmilan and x508 for just reinforcing what I was saying. You see the origional question was to end the app via a dll that was initiated by the app,

>VB5, i think the main question asked here is if it is possible to End an application from within the dll that it is connected to

and you have suggested that the dll raise an event for the program to take action on. In this case end the program.

So SpiderBear6 you have the advice from x508 and mmilan to call the main application via a raise events and my advice...

>Also to answer your question I do not belive it would be a good idea to attempt such a thing.

and a suggested method on how to end your program gracefully (see my origional post).

It's good when we all agree...

Good Luck

Actually I went a different way and returned a flag from the method call, which tells the main program whether it needs to shut down or not.

Thanks for all of your help guys.
