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

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.

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

OK, here's my problem:, , I have this function, function TForm1.Romberg1Integrand(x: Double): Double;, , In Delphisourcecode this function shall looks this:, , function TForm1.Romberg1Integrand(x: Double): Double;, begin, [b]Romberg1Integrand := x*x;[/b], end;, , My problem is, that I want to define the Romber1Integrand in runtime: The user may select a function (in this case it is "x*x") from a ComboBox and the string shall be used as the function. Any idea on how to do this, it's really important!, , Any help is apreciated, thanks in advance.

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

I was asked by someone if I could put together a little program which at the press of a button would shut down Windows (and not just go to a DOS window) and then run a true DOS program and then close the system down - although I doubt this last bit., , Naturally I waved the white flag at this, but hoped that someone here may have an inkling of what to do. , , I understand that the DOS program is something to obliterate the windows swop file, so it did'nt take a great deal of brain power to guess that the said computer may have been visiting the likes of naughty Nora's enormous knocker sites , , Well, each to his own I suppose, but out of interest could this be done in Delphi? , rt

An application I have been playing with has now decided to include some extra files when it compiles, these are designated _qsq1.mb and run on up to say _qsq34.mb., , What are they? And, how can I stop them procreating as I think I have enough files as it is!

Help !!, In a listbox with sorted = True, the string '~sw.tmp' is less than the string 'sw.tmp'. However, when comparing the 2 with CompareStr function, suddenly '~sw.tmp' is greater than 'sw.tmp'. That causes a lot of grief as I loop down 2 sorted listboxes, constantly comparing current entries., , Any ideas ? Help much appreciated., Matt

Hi there, , I have a unit which defines several wrapper objects to direct3D functions. This unit has (amongst others) the units 'directXGraphics' and 'd3dx8' in its uses clause., , These units also contain several functions, objects, records etc (such as TD3DXVector) which are useful for the user., , How do I make the objects,functions such as TD3DXVector etc available within a unit which ONLY has my unit in its uses clause? I don't want the user to have to also add 'directXGraphics' and 'd3dx8' to the uses clause too., , I also don't want to have to define wrappers with different names such as:, type TmyD3DXVector = TD3DXVector;, , Thanks in advance, Peter
