Delphi / .NET interop – Atozed announced Crosstalk
Posted by jpluimers on 2009/05/06
On 20090504, Atozed announced Crosstalk: a technology that allows native Delphi code to consume .NET assemblies in a really intuitive and transparent way.
The announcement contains a FAQ.
It is a promising technology, not only because it is dead easy to use, but also because it is backed by Atozed: a team of people that have made complex technology like Web Apps easy to use by creating IntraWeb.
Expect demos soon (maybe even at Delphi Live!).
Here is a short example:
program TestLeft;
{$APPTYPE CONSOLE}
uses
SysUtils,
CT_System_Text in 'CT_System_Text.pas';
var
MyStringBuilder: StringBuilder;
begin
WriteLn('Start');
MyStringBuilder := StringBuilder.Create('Hello CrossTalk!!!');
WriteLn('Length: ', MyStringBuilder.Length);
MyStringBuilder.Append('More');
WriteLn('Length: ', MyStringBuilder.Length);
WriteLn(MyStringBuilder.ToString());
Write('Finished -- Press <Enter>');
ReadLn;
end.
Output:
Start
Length: 18
Length: 22
Hello CrossTalk!!!More
Finished -- Press <Enter>
Nice!

How do you handle the conflicting FPU settings between Delphi($1372) and .Net runtime(0x027F)? The .net 4 runtime will throw a stack overflow triggered by a delphi application after the runtime is loaded into the delphi process. (i.e. start delphi app, load .net dll, then in delphi app divide by zero a couple times in a row).
Prior to .net 4, the suggested fix was to toggle the FPU to $133F before the .net call then restore it afterward, this does not appear to work in .net 4. I’m using CreateOleObject to create the .net instance.

I’m not sure; if you create a small reproducible example and post that to http://stackoverflow.com you have the best chance of finding an answer fast.
