Brodsky Guest Posted: Tue Feb 24, 2004 3:49 pm    Post subject: What am I missing? Hi All, I am new to Ado. I am using MSJet 4.0, Access DB. In my thread on .Execute, I have the following lines : OleInitialize(nil); Catalog := CreateCOMObject(StringToGUID('ADOX.Catalog')) as _Catalog; But, I don't see anywhere where I am cleaning this up, ie. Freeing or niling the Catalog, or maybe there is an OleUnInitialize(nil) command? All I know is that ever since I put this code into my thread, I am throwing strange AV's randomly, at different places in my thread. Even though I am not even using the Catalog. Any suggestions, TIA, Stacey -- Regards, Stacey R. Brodsky ClubRunner, Inc. www.clubrunner.net Disclaimer: Any included code snippets may not have been previously tested. Back to top Viatcheslav V. Vassiliev Guest Posted: Tue Feb 24, 2004 5:37 pm    Post subject: Re: What am I missing? Use CoInitialize(nil) in thread, not OleInitialize. You free Catalog by setting it to nil. At the end of the thread Execute function you should uninitialize COM with CoUninitialize(). //------------------------------------------ Regards, Vassiliev V.
