Hi Satish, check out the lr_decrypt function, this is probably what you are after …

Cheers,

Hi, I want to encrypt the password while passing these parameterized values within the script. I am basically looking to find if we have a similar function in LoadRunner (as we have in QTP, SetSecure (“test123″))?
Appreciate, if anyone can respond.

Thanks!

Tim,

I found the pcre files at the following site:

For my own reference, you can also get regex pattern matching with this approach. You need to comment out //#include in the pcreposix.h header for this to work:

request_num() {
int  status;
    int  eflag;
    char buf[256];
char out[128];
char *pattern = "requestnum=(\\d+)'|requestnum=(\\d+)&";
//char *pattern = "sen(\\w+)|s\\wn(\\w+)";
char *string  = lr_eval_string("{request_num_buff}");
    regex_t re;
    regmatch_t pmatch[128];
lr_load_dll("c:\\pcre\\bin\\pcre3.dll");
 
if((status = regcomp(&amp;re, pattern, REG_EXTENDED))!= 0){
regerror(status, &amp;re, buf, 120);
exit(2);
    }
 
if(status = regexec( &amp;re, string, 10, pmatch, eflag)== 0){
strncpy(out, string + pmatch[1].rm_so, pmatch[1].rm_eo - pmatch[1].rm_so);
        lr_save_string(out, "requestnum");
lr_output_message("Notify: Parameter requestnum was found: %s\n",out);
eflag = REG_NOTBOL;
    }
    regfree(&amp;re);
}

Hello, Tim.

I appreciated your efforts on working with Regular Expressions in LoadRunner.

I moved forward Charlie’s and your ideas on LoadRunner RegExps. So, now we can use LR RegExp to match subpatterns and to capture (=to extract) all matched substrings.

The solution is located here:
