Paradox Third Party Software, DLLs, and Controls Topic

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. 

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

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...

I have an ActiveX component that I wrote in VB to access a BarCode Label product. When I run the following code it registers on some machines, but others I get an error that says component can not self register. Any ideas:, , if RegisterControl(stringVar) then, msgInfo("Congrats", "Control Registered"), else, errorShow(), endIF, , This is for a Paradox 9 app with the latest patch on Win 9x machines.

Has anyone toyed with a data aware TreeView component activx or ocx Dll etc, that provides functionality similar to the DBTreeView that is in the WllToWll/InfoPower sets for Delphi. Is the List object provided with Paradox 9/10 the answer if so where is the documentation to get indented lists that behave with multiple one to many table structures that would form a drillable outline., , If anyone has please let me know. This is a key missing object in an otherwise pwerfull toolset. , (as I am new to the forum my background in Paradox goes back to building EIS systems in Pardox 3.5 back in 1991 to developement of Enterprise valuation and activity forecasting systems for lage Australian Companies today using Paradox10 and Delphi7)

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. , , I just can't figure out how to fix it....any suggestions?, , abp

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?

I just downloaded (twice) the demo version of Prestwood's Paradox Workbench (wb12-beta1.exe)., , Unzipping and invoking setup appear to work normally, and the readme item is added to the NT start menu. But it doesn't seem to hook itself into the Paradox Tools menu item. I have rebooted after installation, to no effect., , Running Paradox 8.00.302 on NT 4.0 w/SP6a., , Any suggestions?

Hi, i┤m trying to use an external dll to control a hardware system, and i can┤t figer out how it works. The problem is that the manufacture only knows how to use c and has no idea what paradox is!, Here┤s the problem:, I should call a dll function in this way:, , pbGetRawImage(OUT void *image), , Description:Gets an image from the sensor.One byte in image corresponds to one pixel from the sensor. A byte value of 0 means a black pixel, 255 means a white., Parameters:[OUT] *image - pointer to where the image is to be stored. This buffer must be of sufficient size, call pbGetRawImageSize() to determinate the correct number of bytes., , OK! How do I make this work in paradox, and how can i make a file whith the image?, , Any help?, Thanks in advance,, Sergio

Not wishing to be a pain in the.. ummm .. because you are are such busy people, but did you have a chance to look at the couple of problems I sent in regarding the Workbench. Do you want me to send 'em in again?, rt

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.
