i have a single string parameter listing seperated by commas. I am trying to
read in the individual sections into variables. If i enter the parameter
listing in the same function manually to test it works fine, but i have a
seperate function that retrieves the parameter and it works fine and returns
the correct information and when i use the function i need to include the
following line or it doesnt work anymore:

string s =
"ddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd";

its not concerned by the characters its the amount of characters that seems
to be making it work.

say when its working the output is:

"c:\testing location 1"

when i dont include the string s part it will only output:

"c:\testin"

a portion has been supplied, let me know if anyone
knows what im doing wrong, thanks in advance...

e = "c:\\ShortcutTest.lnk";

LnkInfo = Lnk->GetLnkInfo(e); //this function runs the iShellLink functions
to breakdown a shortcuts information.

string s =
"ddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd";

loc1 = LnkInfo.find(",",loc1);
LnkPth = LnkInfo.substr(0,loc1); //this section is run multiple times to
retrieve the information but the it does fail on the first run.

Hi Anthony,

Well for one thing I'd make this change...

char* e = "c:\\ShortcutTest.lnk";

This way you've actually allocated some memory for the string in 'e'.

In my own programs I usually do this.

char ea = "the string";
chat *e = ea;

Or more to the point.

char ea[36];
char *e = ea;

As for as string 's' I assume it's a similar issue but can't tell from the code
provided. If I had to guess I'd guess that the program is finding enough
memory for "c:\testin". But that is only a guess.. Of course a String object
shouldn't need any special treatment. Need more code I think.

HTH,

Bruce

Hi Wolf,

Hey man you are absolutely correct!

(which kinda sucks because I'm trying to be helpful..)

I misread his posting and that didn't help...

Thanks for taking care of that. I'll have to make
sure I read the code in these postings more carefully.

Thanks,

Bruce
