Exception encounter after upgrade from D4 to D7

Exception encounter after upgrade from D4 to D7

Post by Raymond Ch » Fri, 14 Nov 2003 20:43:18


I urgently need help from anyone !!!

I have just finished migrated a D4 Client/Server app (using DCOM) to D7, in
general, both the client and server application seems running OK except when
one of the clientdataset component open a TQuery dataset from the Server
module, an exception always came out which never happened when using in D4
version. And the funny thing is that if I open that clientdataset in design
time, no exception is raised. Is there anyone encounter this problem before
?

Thanks

Ray

How on earth can anyone help you if you don't mention what the
exception is or any other details of your application?

You're essentially saying, "I have an error, why?"

An access violation is a bug in code. It could be your code, or
Borland's. The first step to finding the problem is to Build your app
with Debug DCUs, and look at the call stack when the exception is
raised. This should give you some clue as to where the problem is.

Here is another exception message when I have excluded the midaslib from the
project' uses clause.

"Access violation at address 4DAF5597 in module midas.dll. write of address
0000460D"

I am running both the client/server apps on the same machine with D4 and D7
installed !

Thanks
