Weird Structure

Hey Guys

I have a structure i defined myself which contains a string and a DWORD.

I have declared an instance of this in the header of a class and then i have functions in my class that write to this public variable. Well anyway when you try and read data out in another function the variable is empty.

Has anyone got any ideas

Peter

Your code?

You got any code for the class and the functions?

Beat ya ;)

return TRUE; // return TRUE unless you set the focus to a control

}

MFC-looking code is hard to read like this. At least for me.

Do you know about CODE & /CODE [code in brackets] around the C++ source you paste up?


Thanks.

At least indent it first, I'm normally inclined not to bother even trying to read it if it's unindented.

And also it's MFC so...
