[dba-VB] Odd problem with VB 6 application

Hi Drew,

Interesting.  I only use early binding so the exe must be registered
anyway.
However I ran into a situation a few weeks ago in a TS environment (2003
or 2K I don't remember) where
I had released an update of the ax.exe and after the client copied the
exe to the server somehow the registry
entry was set in such a way that only he could run the ax.exe!  He says
he can't remember what he did ;-/
Normally, unless I break compatability (stuff happens), just copying the
new ax.exe is enough.  

BTW, just wait till your users move to Vista.  Regsvr32 will not run by
default even when you are logged on as local admin...  ;-)
You have to disable UAC.  Not sure about regserver, but I assume it's
the same.

cheers

Subject: [dba-VB] Odd problem with VB 6 application

This is just an FYI to the VB list.  A week ago I made a modification to
a system I've been working on called the ISFE.  The ISFE was monitoring
for new requests and a few other things, but that background process was
slowing the interface down a bit.  The modification I made took those
processes and put it in another .exe (and the two talk through window
messages, something I posted on the AccessD list).  Anyhow, a few days
ago, someone submitted a request saying they were getting the following
error message 'Unexpected Application Error; quitting'.  

 

Here's what caused the problem.  The new 'monitor' application was setup
as an ActiveX .exe, because I created a generic 'event' class that each
monitor event was built on (implemented).  The main application tells
the monitor application what monitors to start (based on the users role)
by sending the class name.  The monitor application then used
CreateObject with that string. Can only do that in an ActiveX .exe.
Turns out, however, that a standard User in a 2000 or later environment
cannot start an ActiveX .exe for the first time, because the ActiveX
.exe tries to register itself, and users with the basic User permissions
don't have the ability to do so.  If a power user or admin runs the
program first, then the users can run it...go figure.

 

Just figured I'd pass this along in case anyone else is using VB 6
still.
