illegal operatin when exiting

[Rachel]

When I try to exit my program at certain points, after it shuts down, i get
an
"Illegal Operation - this program will be shut down" message. (Invalid page
fault at kernel32.dll)

I don't know what to look for that may be causing this. Its only when I
exit. My exit is only had "end" in the procedure.

Could someone tell me the sort of things I should look for that may be
causing this type of error?

Rachel,

Try removing the End statement, then exit the program in the development
enviroment. If the program does not completly shut down without the End statement,
your leaving an object or other reference open. You should not need and End
statement at all to stop your program. Set all your objects to Nothing, unload
all your forms, and set all forms to nothing and you should get a clean exit.


Set MyObject = Nothing
Unload MyForm
Set MyForm = Nothing

Rachel,
It is very tempting to use the END statement in your program, but that
is VERY VERY poor programming style. It is the logical equivalent of stopping
your car by smashing it into a Brick wall, rather than applying the brakes.
Both processes will in fact stop the car, but the first way also has the
unpleasnt side effect of killing the driver, and leaving the car in less
than usable condition.

If you terminate your program by simply unloading the last form, when it
runs as an Executable, it will shut down properly and clean up after itself
as it closes the door. If you use the End statement, you program will commit
suicide and will not have a change to clean up after itself, much less close
the doors.

I've tried unloading all forms, setting them to nothing and any databases
that could possibly still be open, but it still doesn't shut down when i
exit this way. I don't know what object is still open. Its like trying to
find a needle in a haystack.

Could it be a common dialague control?

Is there something I'm supposed to do with the common dialogue control after
I've finished using it?

I found the problem. I have a procedure in my form load event :

Call frmCosts.ReadtheRegistry

to get some values from some text boxes on that form which i use in the main
form.

but when I put

set frmCosts = nothing

in my main form's unload procedure, it still will not end the program.

If i dim out the Call frmCosts.ReadtheRegistry, procedure from my form load
procedure, then the program will end with my unload procedure with out an
end statement. But i need to get those values at some point. Is there some
other way to set that form so it doesn't interfere with my unloading
procedure?

Just wanted to thank everyone who helped here. I finally have my program
exiting correctly. Apparently needed to unload again as well as set it
nothing. Now when i make the distributed disk, it no longer gives the
illegal operation message when I shut down.

All this time i've been learning VB, I never knew you weren't supposed to
use the END statement for exiting. I guess it never came up before. I am
curious though if anyone feels like responding to this, when if ever you do
put the end statement in your program.

Thanks
Rachel

Rachel,

"when if ever you do you put the end statement in your program?"


That has a VERY simple answer ---> NEVER!!!!

unless you want the program to commit suicide.

Racheal,

I use the END statement only if I'm afraid further program execution will
do damage to other components my code interacts with. For instance, when
I handle an error in code that is writing to our corporate database, I
prefer END to other methods. This may be considered sloppy by some, but
Not corrupting sensative data is more important.
