Hello,

another question: how can I get global string variable for a process then save it? I want to put the LISP global string variable *CI_Ido* into str string variable using the getsym function. I have an rstring, and I want to convert to a string:

int rc;
struct resbuf *rb;
string longT,
         str;
rc = ads_getsym(_T("*CI_Ido*"), &rb); 
if (rc == RTNORM && rb->restype == RTSTR) {
     str = rb->resval.rstring;  /* this my question */
     if (str.length()==17) {
	longT = str.substr(14,4) + "." + str.substr(1,4);
	rb = ads_buildlist(RTSTR, longT, 0); 
	rc = ads_putsym(_T("*CI_Valt*"), rb);		
	ads_rett();
     }
     else 
     {
	ads_retnil();
     }
} 
else 
{
     ads_retnil();		
}
ads_relrb(rb); 

 many thanks,

Csaba

What exactly is the problem? Build error? Runtime error? Crash?

Not string but wstring

ACHAR *

{ int rc;
  if (variabile==NULL)
      {
          ads_retnil();

  struct resbuf *rb;
  rb = ads_buildlist(RTSTR, value, NULL);
  rb.rbnext=nil;
  rc = ads_putsym(variabile, rb);        
  if (RTNORM==ads_retstr(rb->resval.rstring))
    { ads_relrb(rb);
      ads_retstr(value);
      return(value);
    };
  ads_relrb(rb);
  ads_retnil();
  return(NULL);

The error was: no operator "=" matches this operand.

The wstring type has resolved it, and this one is the easyest way for me, but I will test the 2nd solution and build in.

Maybe you ask why I need ObjectARX for this process, why not enough LISP, because it's a test and I need to compare the results of LISP and ObjectARX.

Thanks for everyone the answer!
