Hi, I have a COM class library that is reasonably big, say 12 classes in it. It compiles in about 15 seconds. But when I try to debug it, by starting it, I get a delay of about 3-4 minutes, and then again a delay of about 2 minutes when I stop it! I am using VB6 SP2. I tried re-installing...

Hi, I was wondering if anyone could tell me if it is possible to access a file on the web server from a COM component in a distributed environment? My COM component does this currently since the COM components run on the web server, but if I was to use DCOM to run the COM components on another...

Hi all, We are experiencing an ORA-04031 error when we try to run a SQL statement that contains 3 IN statements - e.g. "where X in (1,2,3,4,5..)". The numbers that are in my "IN" are all parameterized, so theres quite a few parameters (about 260). This seems to cause oracle to fail and run out...
