Is dll developed in Delphi 6 works on Delphi 2?
I have a one dll, whose work is to creates a form with some normal vcl controls, print selected tables and email some reports. It was developed in Delphi 6. Can any other application which was developed in Delphi 2 use that dll.? If not, please let me know in which areas i need change. The dll work is only to print and email. With regards, Srikanth Varma

It all depends on the DLL interface, which types of parameters are passed to the DLL, whether it needs to use a shared memory manager with the host exe, or even share packages with the host. If the DLL was build using Windows API compatible parameter types only it should work. -- Peter Below (TeamB) Don't be a vampire (http://slash7.com/pages/vampires), use the newsgroup archives : http://codenewsfast.com http://groups.google.com

The dll work is to create a form with some third party components like exportToPdf and some Reporting components. Only D6 supports these components but D2 not. Will that dll work in D2?

But this all depends on how the host application interacts with the DLL, and you have told us nothing about that yet. What functions does the DLL export for the host application to call? Post their declaration and we may be able to give you a more specific verdict. -- Peter Below (TeamB) Don't be a vampire (http://slash7.com/pages/vampires), use the newsgroup archives : http://codenewsfast.com http://groups.google.com

DLLInstance := LoadLibrary(Pchar(sDll));
if DLLInstance = 0 then
begin
.....
end;
@CreateReportD6 := GetProcAddress(DLLInstance, 'CreateReportD6');
if ((@CreateReportD6 <> nil)) then
begin
if not CreateReportD6(Arrgs, richEdit1) then
..........
Arrgs is an Variant array and the second parameter is RichEdit.

The Variant will not be a problem, but the richedit parameter will likely cause problems since the DLL will assume that it is a D6 TRichedit, which it is not. Whether it actually will cause a problem depends on what the DLL does with this parameter, and how big the changes in TRichedit and its ancestors were between D2 and D6. I don't have D2 around anymore, so cannot check this, but there are probably substantial changes since the VCL in D6 was modified to make it easier to reuse as much as possible with Kylix. I assume you cannot change the D2 application, perhaps not even rebuild it after a minor change. Otherwise I would suggest that you change the parameter to a window handle (HWND) and pass the richedit1.Handle. The DLL then also needs to be modified, it has to use API methods (send messages) with this handle to get data out of the richedit or modify its content. -- Peter Below (TeamB) Don't be a vampire (http://slash7.com/pages/vampires), use the newsgroup archives : http://codenewsfast.com http://groups.google.com

Trying to call a .DLL from Delphi XE (used to work with Delphi 6 :-) )
Hi everyone, I have a problem where perhaps some one could help point me in the right direction. In Delphi 6 I used a stand alone package to train a neural netowrk,. The trained neural network was stored as a .DEF file. The standalone software provided a .DLL and Delphi code to call the network and get the prediced values from your sw. (The .DLL was created in 2002 and apparently is 32 bit.) I have'nt used it for years but am now coming back to it.... I now use Delphi XE on Windows 7 (32 bit) The old .exe's I had compiled from that time work fine. However in Delphi XE ...
Calling Delphi 6 DLL from Delphi 2010
We have a Delphi 6 dll that has a PChar passed to it. The dll function then does a search and returns a PCHar. This works good using Delphi 6 to call and recieve the dll result. We have upgraded our calling program to Delphi 2010 and most of the time, the value is passed back just fine. However, we do have times when we get an access violation, when calling the dll. The dll does process the request. Below is the code. Has anyone had a similar issue using an older version Delphi Dll with Delphi 2010? I am sure that Unicode has something to do with it, but not sure how to fix th...

dll fails when compiled with delphi 2010, but works with delphi 7
I may be doing good if someone can just point me to the right forum I have not created a dll for some time and have not written one with 2010 before.

Delphi 5 to Delphi 6 conversion
Hi We are moving our product from D5 to D6. I have dealt with all the deprecated functions. However, we are getting various platform specifc warnings.

We don't view the simple solution of switching off those warnings or symbols as being the correct way. What we want is the same platform independence as other functions. For example, all o...

ShareMem Delphi 6 --> Delphi 2009
I have just upgraded from Delphi 6 to Delphi 2009. My software uses about 20 files, plus literally dozens more plug-ins. Every project has ShareMem as its first unit and borlndmm.dll is distributed with the software. I am aware that the Borland Memory Manager was replaced to use FastMM quite some time ago. Will I have to rebuild every EXE and DLL in DElphi 2009 that uses ShareMem, or will supplying the new borlndmm.dll be enough? i.e. I would like to just update the main application EXEs and DLLs, but leave the plug-ins alone.
