Hello! As a self-taught casual programmer, i'm having a bit of trouble with Delphi 3. I'm trying to play about with the TCP demo application. It works fine on my machine but when I try it other pc's I get the following error:, , Exception EOleSysError in module DCHAT.EXE at 00032EF9. Class not registered., , I think its got something to do with setting up ActiveX and STDVCL32.dll but other than this I'm totally stuck! Any help would be greatly apreciated., , Cheers,, Tarquin

Hello pals,, , I have a Delphi application connecting to an Oracle database sitting on a Citrix server. When I try to do certain things I get an error 'Access violation at address...' The application was not developed inhouse and I do not know Delphi & Citrix so I can't guess why I get the error message. I get this message even when I am logged in as administrator on the citrix server and try to open a client session from there. The application runs without any problem on Windows NT/98. The problem seems to be specific to Citrix and Delphi, can anybody please help., , Hope I have given enough details., , Thanks,, , -Shyami

I wrote a program by D6 personal. Initially for fun, but now it turns out I may sell it for some money. Does anyone know how much money I need to pay borland if I want sell a program written by D6 per? I'm a student, $1000 pro version is too much for me. I hope I will not need to re-write it by c++. Borland's tools are excellent, but the price is a little high.

Hello delphiers,, , Im not sure if anyone of you have come across this error message "Class not registered". I get this message when i try to create a COM object which starts communicating with the respective client-side program., , The client-side program in context is Lotus Notes 6.0.3. I have installed it on the same PC where I have Delphi 5 Ent installed, I also have run the notesws.reg file which adds the relevant registry entries. The .tlb files in the \lotus\notes\ directory are also installed in Delphi., , The moment I create the NotesSession object, I get this error message., , Somehow i feel that the classes are not able to find one or more keys or CLSID or GUID written into the registry. I traced through the .Create method to be able to make this guess. The GetSrv or GetServer method fails in the .tlb / OleSys.pas file., , How to go about fixing this problem? Where should i look? What is not yet installed or configured?, , Regards,, , Mani

Hi there,, , Does anyone know how to clear the text dispplayed in a combo box? Mine just holds the last value and doesn't overwrite it when I tab back to it ideally I want it cleared and ready for the next entry. , , I've tried setting .Text := ''; but it doesn't work even if I set it to '1'; it doesn't display a 1 only the previous value. The whole text line seems to be higlighted rather than just the text. Any ideas?, , Thanks, Mully

On a system, two different applications are installed. One uses BDE 5.01, one other uses BDE 5.1. , When ran separately, both applications work well., However, when we try to start one application while the other one is running we get either an error $2501 at BDE initiatlization, or a Windows Error (the application generated an error and will be closed)., 1) What is the meaning of error $2501 ??, 2) Is there anything we can do to avoid this incompatibility ?, Thanks for your help

I have a problem passing and returning an array between an ASP page and a Delphi COM Object., , I create an array and pass it to the COM Object like this:, , arr = obj.ArrTest(Array("element1","element2")), , The function is defined as:, , function ArrTest(varname: OleVariant): OleVariant;, , Inside the function if I try to treat varname as an array it doesn't work. For example testing for an array:, , VarIsArray(varname);, , returns False., , Similarly if I create a Variant Array inside the COM Object and return it to the ASP page it seems to go wront., , Can someone give me a simple example of how to do this., , Thanks, emets

Am using CodeGear 2007 Win32 with dBase, ACE Reporter, Woll2Woll, JEDI components; therefore I have a lot of TTables and TQueries throughout my program. My applciation runs on a 2003 server with XP workstations. The response time to access data (retrieve, post, do SQLs) is horrible. The users are demanding something better. But I don't know what is better. And I don't know what the ramfications are in changing to something better. I sincerely hope that someone can give me recommendations as well as address the difficulty in changing to another database. Thank you so much, Charlie

Is there a more efficient way to look up a value in an array then this:, , for i := 0 to length(myArr) - 1 do, begin, if myArr[i] := myValue then, found := true ;, end ;, , something like, if myValue in myArr then, found := true ;, , probably a stupid question, but I'm only using Delphi occasionally (though I love it)., , TIA,, Matt
