| It seems fairly simple. If not, isn't it just a matter of adding a couple of lines of code at the top of your while loop? Just test the szLine before you copy it. Loop until you find a non-whitespace character and then don't perfrom the strcpy if you detect that the line is blank. By blank I assume it means that szLine is either a null string or it just has a few spaces correct? | |

| Hi , Thanks for that reply but still did not get it. szLine is declared as CHAR szLine[4096]. And as soon as I get a complete blank line my program crush. I still not sure how to check szLine for a blank line .. Appreciate your help.. Thanks, newbie ..! | |

| fgets() will put the newline of an empty line in the buffer, so testing for strlen() == 0 won't work. Check if the first character in szLine is a 0, newline or carriage return. | |
