I'll tell you the sad story, but some solutions do exist.Unfortunately, this version of Delphi had limited support of Unicode. Borland VCL was not Unicode-enabled at all, so, with the controls you are using, you cannot do anything at all. You would need some custom controls replacing VCL....

could you please provide me with the equivalent assembly code relatedto the code written in C++, " tracking code form live camera"best wishes

8 Aug 2010 by Christian Graus

What does this have to do with javascript or delphi ? Compile your C++ code, and then read the assembler that is produced. No, we're not going to write it for you, that's an insane amount of work.

8 Aug 2010 by DABBee

You dont really mean you want the assembly code do you. Surely you meant to say something else - please check your question - look up what assembly code is, I suspect you are not clear on this.NOP

8 Aug 2010 by Sauro Viti

"tracking code from live camera is a vague sentence, but I suspect that there is a lot of work under the scene: if you can do the work using C/C++, why do you want to do it using assembler? It could be a titanic work, hard to do, error prone, and difficult to debug!
