well,you could enclose it in a try ..... catch and get the message of the exception and find out,if there is no exception message,then the file would have been executed 'completely'

Sonia Gupta15-May-07 19:59

is there ant alternative way out ?
once the program enters into the catch block.it takes time to complete the execution.thus increases the access time.

if you use a generic exception such as "Exception" it will take a lot of time,to reduce that time you have to choose a more specific exception.The more generic your exception,the more longer the processing time.So its a compromise between Accuracy and Speed.

i actually do not know how to check whether the particular exe has been executed completely.

subclassing only in runmode

16-May-07 3:34

What do you mean by "execute completely"?? Are you asking if the child process terminates? Are you looking for an exit code? A file waiting to be written?? What?

Is there a way to determine when i'm in runmode in vb6. I don't want to subclass a window when it is in design mode.

There's a way to determine when the program is running in the VB IDE context.
Are you asking for this?

yes (i think). I have a usercontrol and in there i subclassed one of the constituent controls, but I only want this subclassing if i'm running and not while it is sited on a container in the design mode.

Do you mean an ActiveX control?

It's been a very long time since I've used VB6. But, I can't seem to recall if there was a property to tell if you're running in design mode or not. I don't think there is, but I could be wrong.

I've tried this already and it doesn't do what i want. I want to know when my activex control is in run mode or design mode b/c i only want to do the subclassing when it is in run mode.

Sorry, I misunderstood.

Private Sub SetMode<br />
   On Error Resume Next<br />
   gbDesignTime = Not (Ambient.UserMode)<br />
   If (Err.Number <> 0) Then gbDesignTime = False<br />

   On Error GoTo 0<br />
   Debug.Print "Design time = " & gbDesignTime<br />

let the first menu item be item1 and the second be item2,then,write this in the click event sub of the first item

item2.performClick()

This way item1 is linked to item2,ie,if you click on item1 it will perform the click event code of item . Is this what you wanted to know?or is it something else?

Ya might want to find out what he means by "link 2 menu items" before you go throwing around example code. Like Christian asked the OP already, what does "link" mean?? I can think of half a dozen different meanings, seperate from what you posted.

He might now be thinking this is the answer to his question, when in fact he meant something completely different. Now, he could be wondering why it doesn't work the way he thought it should!

finalize [modified]

Sonia Gupta15-May-07 18:48

class class1
protected overrides sub Finalize()
mybase.Finalize
End Sub
end class

If Garbase collector cannot determine automatically the object which is no longer being used -- then what is the advantage of using the finalize function in each class -- which is defined above.

i meant the finalize function gets called automatically when i close the startup form.
currently i am manually releasing the memory of a paticular object at form closing .

The framework WILL call finalize, you just can't tell when. The best approach is to impliment IDisposable and to clean up your resources in Finalise, only if Dispose was not called.

provide an expmple.
Thank You Christian.

Impliment IDisposable and you'll have a Dispose method. Call it to clean up.

i have got the article for idisposable
at
http://www.codeproject.com/useritems/idisposable.asp[^]
i will study it and one more thing

1.that means Garbage collector get called automatically when the startup page closes. rather, the particular form automatically invokes the garbage collector everytime, whenever the object is no longer used.
Is that true?
