LoadRunner Correlation

Scraping Binary Data within LoadRunner Scripts

Using Winsocket...

The left boundary is composed of 3F and DD. The right boundary is composed of CC and b.

So:

web_reg_save_param("ParamName",
                   "LB/BIN=\\x3F\\xDD",
                   "RB/BIN=\\xCCb",
                   LAST);

For whichever boundary, use BIN with LB and RB, then web_reg_save_param() can be used with binary data.
