Based on the search item I choose, I want a different transaction. This pulls the transaction name from parameter file and generates the transaction name off the “SearchFieldTransaction” column in my parameter file. Be careful. Tree view will take the “tmptransactionname” out of the lr_start and lr_end transaction.

Code:
Action()
{
char tmptransactionname[25];

sprintf(tmptransactionname,”%s”,lr_eval_string(“{SearchFieldTransaction}”));

Today’s code comes to us from Anthony Lyski:
“I ran into an issue today where I needed to know id an integer was an odd or even number. I found that this is a very effective way to determine. I put this code in a ‘for’ loop so you can see how it works over a range of numbers.”
int i;

for (i=0;i<100;i++) {
if (i & 1){
lr_message(“%d is odd”, i);
}
else{
lr_message(“%d is even”, i);
}

Lets say you need to grab a list of items or numbers from a web page, such as GUID’s. These are not dynamic numbers, but will be used in a script as parameters. Here is how I captured the data I wanted and created my own DAT file:

Figure out the format you want the DAT file to be in. For me, this was a GUID, another GUID, and a user ID. I created a file and put the top line in with the headers GUID1, GUID2, LOGIN and saved it to my C: drive in the root folder. I already knew the login so I had already set this up a a paramet Read Entire Entry

In my custom load testing class, we usually get into specific code examples that demonstrate how to do some tips and tricks in VUGen. One of the things I always like to bring up is the behavior or sprintf. This is a commonly used C function for string manipulation. Many a young LoadRunner lad has come across the dreaded memory violation error in their output log when using sprintf:
Error: C interpreter run time error: Action.c (10): Error — memory violation : Exception ACCESS_VIOLATION received.
Let’s look at why. Here is some code: Read Entire Entry

I was trying out the new Protocol Advisor in LoadRunner 9.5 this week, and I found it was not working as advertised. It wasn’t even recommending WEB as a protocol choice for recording a simple web script. Not good. The only thing it did recommend to me properly was RDP. If a person cannot figure out they are using RDP when they launch an RDP window, they probably should not be using LoadRunner. 🙂 I decided to dig a bit deeper and found I had discovered a bigger problem.

On my past several engagements, I had been using the client Read Entire Entry

This was developed as a result of load testing a bridal registry site written with BlueMartini. There needed to be a way for the Vuser to clean up its bridal registry at the end of each iteration. However, I couldn’t be assured of a specific number of items (because the item catalog changed frequently, and we varied the number of items added).

The web_submit_data function looks for a symbolic “LAST” to determine when it has reached the end of a variable argument list. This was modified by inserting it into a predefined argumen Read Entire Entry

This function (called EncodeText) may be a bit out of date, but can be used to replace special characters and use different encoding. You could put this in the very top of the vuser_init section of your script, or in the globals.h or other include file.
//——begin code—————
EncodeText(New,Orig)
char *New;
char *Orig;

int New_index;
int Orig_index;
int len;

len = strlen(Orig);
