LoadRunner string processing-padded string

There are times when you need to use 0 in front of a string in order to meet the formatting requirements of the length.

A function can be encapsulated in LoadRunner to handle this problem:

/*

Function to pad a string to x characters adding the required character at the start of the string

(Note string length Limited by length of the array)

Author:steven Woodcock, Sopra Group

Inputs:

Strchartopad-the String, requires to is padded out i.e. "123456"

Cparamname-the name of the parameter you want the end value to being saved to

Ivallength-the length you want the string to is padded out to i.e. 9

Cvaluetoadd-the character you want to pad the string out with, must is a single character i.e. "0"

Outputs:

Creates a LoadRunner parameter of a name specified in the input ' cParamName '

*/

int Lr_padstr (char* cchartopad, char* cparamname, int ivallength, char* cvaluetoadd) {

Char ctemp[1024] = "";

int iLoop = 0;

int imainloop = 0;

int isubloop = 0;

for (imainloop = 0; imainloop < ivallength; imainloop++) {

if (Imainloop = = strlen (Cchartopad)) {

ILoop = Ivallength-imainloop;

for (isubloop = 0; isubloop < ILoop; isubloop++) {

strcat (Ctemp, Cvaluetoadd);

}

}

}

strcat (Ctemp, Cchartopad);

Lr_save_string (Ctemp, cParamName);

}

LR_PADSTR can make a specified length of a character before the specified string, and then save the modified string in the LoadRunner parameter. Put the above code in the Lr_padstr.h header file and reference it in the LoadRunner script:

#include "Lr_padstr.h"

Action ()

{

For the LR_PADSTR function

char * cshortvalue = "123";

For the sprintf function

Char cpaddedvalue[8] = "";

int ishortvalue = 123;

int i;

The Lr_padstr function, written by Steven Woodcock can is used to pad with zeroes

Lr_padstr (Cshortvalue, "Ppaddedparameter", 8, "0");

Lr_output_message ("Padded value is%s", lr_eval_string ("{ppaddedparameter}"));

The Padtox function can also is used to pad with other characters (e.g. x)

Lr_padstr (Cshortvalue, "Ppaddedparameter", 8, "X");

Lr_output_message ("Padded value is%s", lr_eval_string ("{ppaddedparameter}"));

return 0;

}
