QC and Load Runner Integratio​n

Got below response from one of the HP support personnel

 

You have to consider also the versions. LR 11 can only work with QC 10. Check the Controller and Vugen guide for more details.

If you are customer you can try posting on our internal forums for more personalized support.

Removing char from string
========================
#include
 void remchar(char *s, char chr){
  int i, j = 0;   for ( i = 0; s[i] != '\0'; i++ ) /* 'i' moves through all of original 's' */  
{     
     if ( s[i] != chr )     
 {
         s[j++] = s[i]; /* 'j' only moves after we write a non-'chr' */
       }
   }

   s[j] = '\0'; /* re-null-terminate */
}
 int main(){ 
 char text[] = "The quick brown fox jumps over the lazy dog.";
   printf("before : %s\n", text);
   remchar(text, 'o');

PuTTY
=====
First, let's clarify the terminology for you.
1) putty is not a command, it is a standalone terminal client.
2) putty does not have commands. The 'commands' depend on what server you are connected to is using as a shell. In this case, it SOUNDS like you are connecting to BASH. A quick google of 'Bash commands' will tell you what commands are available. Putty can also connect to winblows servers or servers that run entirely different command sets, and even old school dialup BBS systems.
3) Downloading files in a BASH session will NOT store them on your computer but on the server you are connected to - there really is no practical way to move files from a remote bash session to your local system unless your local system is set up as an FTP server. You want to grab files from your remote system, that's what FTP is for. If your FTP login doesn't have access to the same directories as BASH or whatever shell you are logged into, copy the file to a directory you DO have FTP access to.
4) This has nothing to do with programming

Why ping throws request timed out message.

6down vote

A ping is an ICMP packet. For comparison, web traffic or HTTP, is generally a TCP packet on port 80. A given server may be providing responses for the purpose of web traffic, but block ICMP (or be behind a firewall that blocks ICMP) and therefore you can: Resolve the URL to its IP address Connect and view the web content But you cannot ping the IP address. The response "request timed out" is because your client sends the initial packet, waits for a reply (which will never come), and gives up at a preset timeout

Floor Function In Loadrunner

My collegue came across a situtation where he needed to convert a correlated value to floor. Any value with fractional part greater than .5 should be converted to next nearest integer. However, the valueswith fractional part less than .5 were normally getting converted to nearest lower interger.
e.g.
4.2=4
4.6=5
We came up to a solution that works in this case

double inputval =  4.454567878E8;

> double result = floor(inputval + 0.5);
