File operations in loadrunner with examples

In this post I will explain how to capture a value from server response and save to a text file using vugen.

How to capture and save to text file using loadrunner:

First I have recorded the script using bing.com and then i searched for IBM. We will get 10 results. I have captured all the 10 values and saved to a file.

Here is the code for that.

    long fp;---Here I have declared fp to store the buffer that captured.
    int i;
    char *SearchValue;
    char ch[1000];

    web_url("www.bing.com",
        "URL=http://www.bing.com/",
        "Resource=0",
        "RecContentType=text/html", ----------
        "Referer=",
        "Snapshot=t1.inf",
        "Mode=HTML",
        LAST);

    web_reg_save_param_ex(
        "ParamName=c_search",
        "LB/IC=< h2 >=\"",
        "RB/IC=\"",
        "Ordinal=all",
        SEARCH_FILTERS,
        "Scope=body",
        LAST);

    web_url("search",
        "URL=http://www.bing.com/search?q=ibm&qs=n&form=QBLH&filt=all&pq=ibm&sc=8-3&sp=-1&sk=&cvid=7edfd3e3530644d79148f56dfad4aa0a",
        "Resource=0",
        "RecContentType=text/html",
        "Referer=http://www.bing.com/",
        "Snapshot=t7.inf",
        "Mode=HTML",
        EXTRARES,
        LAST);
  
    fp=fopen("Loadrunnerz.txt","w");
    for(i=1;i<=lr_paramarr_len("c_search");i++)
    {
        SearchValue = lr_paramarr_idx("c_search", i);
        fputs(SearchValue,fp);
        fputs("\n",fp);
    }

fclose(fp);

Hope, most of the code is self explanatory. If you have any doubts feel free to leave a comment.
