Crash on string compare

[MrHenry]

Hello, i'm having a problem where my program is crashing everytime it reachs a certain point. I get the error "test001.ex e has encountered a problem and needs to close. we are sorry for the inconvenience".

Now, i've put cout << "display"; on every line to see where the crash occurs, and it happens with this statement
"if (strcmp(line.c_ str(), "Importance : High")==0 )",
i've tried replacing it with "if (line == "Importance : High"){", yet it still crashes.

Im using visual studio 2008, but when compiled on my friends dev-c++ the code works fine. I can't switch IDE though. Im not sure what is going on here.

If I press debug I get the message "An unhandled win32 exception occurred in test001.exe [4612]. Then when I open the debugger I get "unhandled exception at 0x1049191c (msvcp90d.dll) in test001.exe:0xC 0000005:Access violation reading location 0x00000018.

It then goes to the xstring file and goes to this line:
size_type __CLR_OR_THIS_C ALL length() const
{ // return length of sequence
return ( Mysoze);
}

the following screenshot shows more detail:

return 0;
}



string checkpriority (string filenameandpath ) { // my function

string line;

cout << "Opening file..." << std::endl;

cout << filenameandpath << std::endl;

fstream myinputfile;

myinputfile.ope n( filenameandpath .c_str(), ios::in | ios::out );

if (myinputfile.is _open())
{

while ( !(myinputfile.e of()) )
{
getline(myinput file,line);

if (strcmp(line.c_ str(), "Importance : High")==0 )
{
cout << "Found match." << std::endl;

return "Importance : 1.\n";
}
}

myinputfile.clo se();
}
}

Really strange: according to your watch window, 'this' pointer during call to some member of 'line' is null. Did you try to debug it?

Try someting like this:

if (strcasecmp(lin e, "Importance : High") == 0) {
}
