How do I set location for .NET control file
When I want to open the files on my server I get the message; "You have attempted to open a database that is in use by someone else, but data can't be shared. You must set the location for the .NET Control file." Of course the file is not in use by anyone else.  I appreciate knowing your suggestions/replies for how to set the .NET Control File location. Thanks

To access Paradox tables, all applications must be pointing to the same Net Dir which controls table and row locking. Run the BDE Admin control panel applet to set the Net Dir.

Hi Phil, many solutions but PDF995 seems to be what my ObjectPAL developers prefer. Try it out and let me know. It does cost $9.95 but it's well worth it.

Has anyone else tried this software? I've heard previous versions recommended many times, but I just got the current version (6.0) and I'm having a _lot_ of issues with it. I've sent an email to them about it - waiting for a response. I'd be happy to provide specifics of the issues if it would be helpful.

Hi Beth, Sounds like the old typeCasting problem.  Don't know if this will help - but can you use a generic type for the argument?  I'm guessing this is Delphi - and it's been a while - but the argument type has to be some thing generic like "anytype".  You can then re-cast it as an array once you have the return value.  Ric

Database Synchronisation
Does anybody remember a version of Paradox that was shipped with a synchronisation utility?  The utily was a third party app that would sync a local and remote database so changes in data on one would updated to the other.  I am developing an application that would be deployed on laptops and these would sync with a central database as and when convienient - maybe someone knows a better way to to do this?  We have abandoned terminal services, i haven't even attempted a paraodx web app...

Well, it was late here in oz so I didn't look at the hop to and being a first time user you better tell me where I should stick it? is it Object pal or Paradox power programming? , , Oh by the way thanks for the help I would have thought that given paradox's paradoxical marketing and failing distribution state I might have been greeted with a helpful response rather than another question.

DLL & General Protection Errors
Anyone had any experience with General Protection Faults when calling a Windows DLL?, , I'm working on Paradox 10 on Windows XP and I'm using the following command:, , ExitWindowsEx(0,0), , It works in conjuction with the form uses:, , "user32.dll", ExitWindowsEx(uflags clong, dw clong), , This code works just fine in some of my forms but others seems to be problematic. On the problem forms, when the ExitWindowsEx(0,0) line is executed it consistantly produces an Unexpected General Protection Violation Error...lovely. Bomb! , , I just can't figure out how to fix it....any suggestions?, Think! , abp

I've seen LOTS of GPF in conjunction with libraries., , Generally, you want to put USES for Windows stuff in its own library. Anything over 64k in size and the GPFs start showing up.

How to pass a NULL pointer to a DLL
I need to have access to some system DLLs from Microsoft. In some cases it is possible for example to get the size for a transfer/string buffer by passing first a NULL pointer to the function, later allocating space for that buffer and later call the same function with the address of that buffer., , For the second functionality it is necessary to declare the function in the Uses section with a CPTR argument (instead of CLONG, which allows directly to generate the NULL pointer). By this way every variable is passed by its address. How can I now directly pass a NULL pointer to the function without using an intermediate DLL exporting two different functions covering the two different functionalities by calling the desired function in the original DLL with different arguments?

C++ DLL's
I am new to Paradox 9 and would like use C++ and the BDE to directly import a 20,000 record flat file right into a table. I have two questions, 1st, is this possible (with C++ Builder I assume..) and on a much more basic level, how to I access a C++ compiled DLL? I have started with:, , extern "C" int SomeFunct(void);, , int SomeFunct(), {, return 50;, }, , In the TESTDLL dll which I have in the uses block of the object. It compiles fine but I keep getting the message "Cannot find reference 'SomeFunct' in DLL." It appears to load and find the DLL but can't find the function. I'm currently using MSFT Visual C++ for this simple test. Any help appreciated.
