    Help! Need some clarification.


    I have these ff. code:
    /*test/dummy progam*/
    #include <time.h>
    //var declaration
    clock_t start, finish;
    double  duration;
    double  limit = 5.00; // roughly equal to 5 seconds
    int x;
    int main(){
        start = clock();
                finish = clock();
                duration = (finish - start) / CLOCKS_PER_SEC;
                if(limit < duration){
                     /* do stuff....*/      
                     printf("round %d",x++); // for example
                    start = clock();
                    duration =0.00;
    return 0;
    I know that this is not resourece friendly type of code. The code above is a test/dummy program ,the program while running will execute the printf() in every 5 second.
    The test/dummy program works fine but when I try to insert this logic to the project that I'm currently working on , it does not work.
    The project mentioned here is converted/or run as a Windows service.

    I've written the test/dummy program as a Win32 console application. The project that I've mentioned is previously a Win32 console application before it is converted to run as a windows service.

    Can anyone tell me why this is happening?

    I'm Using MVC6 and my os is Win2K.

    BTW: when I tried to convert the test/dummy program run run as a Windows service, the test/dummy program does not execute - I mean does not print ( I've change the printf() to a writeToLog type of function).

    any kind of help will be appreciated.

    edit: the test/dummy program above is somewhat my solution to my previous thread A Timed Function in C

    I assume it's because you are setting up the unbreakable while loop and then not letting any of the Windows code execute. You may look into timer API's.

    You're supposed to use difftime() to figure out the difference between two clock_ts, not x-y.
