Call DLL problem

[NewsArchive]

I am having a problem with a dll that I call during my setup

I call the dll before installing files
I check to see if the person is eligible for an update. if they are, the
install continues, if not a message is displayed and the install is aborted

What is happening sometimes, not all the time
the install calls the dll and the install then exists, no message or
anything


when I test on my development computer, the dll works everytime but on other
computers it doesnt

I dont know why

99% of the time, the install directory is c:\bmwin


My call dll screen is attached
I dont know what I am missing

Eric,

Perhaps your update.dll causes a buffer-overrun?

how would I know?

It works every time on my development machine
I have tried it on another computer and cant get it to work - but based upon
further testing, its doing what it should - exit the install

so what is happening is the dll is either not being called or in the wrong
directory
how can I make sure the dll runs in the _sb_installationdir folder?

Only you know where a buffer overrun occurs in your system because you have
developed the DLL.

It may always work on your machine(s) because your test data do not produce
a buffer overrun, etc.

You told me that the install exists, no message or anything. That means the
DLL *is* called, a buffer overrun occurs and the Win32 application simply
"disappears".

IMO, it's definitely caused by a buffer overrun.

HTH,

I think you are correct - I added some message statements to my dll and my
install script and the dll does not run when I download the install from my
website on a computer (not my development computer)

Since the dll does not run, does that mean that something I am passing the
dll is causing the buffer overrun?

I am trying to send the dll the installation directory
so in parameter I have *CSTRING
in the Function Parameters I have
%_SB_INSTALLDIR%

Or is it usually something else?

This could be too obvious, but I'll ask, did you compile your DLL as LOCAL?

Yes I compiled as local

Did you include the update.dll as service file in your installer?

If you are interested, you can send me your SetupBuilder 6 script (.sb6) and
your DLL and I'll check this for you.
