Hello,
I try to use WinExec method to use it with the "rar.exe" compressor. or
"winrar"
 is it the good way?
Question is there another method to launch exe files with arguments?(but not 
as complicated than "CreateProcess"
I have looked at the Window SDK and C++ library and have not find
compression methods or algorithms is it normal?
I have tried with rar.exe and winrar.exe
My code is :
//-------------------------------------------------------
char nomacopi[100];
AnsiString arguments,nomagicler,chemapplic;

chemapplic=ExtractFilePath(Application->ExeName);
// nomrar is read in a TStringList
nomagicler=chemapplic+nomrar+".rar";
//Erasing existing rar file
if(FileExists(nomagicler))DeleteFile(nomagicler);
//command
//rarfiles.lst is build from a TStringList containing directories path
arguments=chemapplic+"winrar a "+nomrar+" @rarfiles.lst";
strcpy(nomacopi,arguments.c_str());
WinExec(nomacopi,SW_HIDE);
//----------------------------------------------------------
The program stops in the WinExec command and show the CPU windows stopped in
the rar.exe thread.
(I don't understand the cpu window and how to use it)
I have try it in the command line window and rar works fine
I have tried wrinting the exact path in two cotes in the WinExec's first
argument => nothing is created
I have tried with "argumen.c_str() in the first argument too but it stop at
the cpu window too

If you have any idea say to me please
Or if you have an other way to compress directories!!!!
I thank you very much in advance
And excuse my English
