For some reasons I can't read from the file Distributor.dis, though the file already exisits...

[parksie]

A few things I noticed:

1. Labels? You don't need them unless you're using goto which you shouldn't until you fully understand its implications

2. Formatting! Don't smack everything on one line because it's a ***** to debug

3. Stop mentioning god or I'll be forced to go on a murderous rampage round Malvern

And to solve the actual problem, I don't remember if it automatically opens the file but if it does, then you can't open it twice because it will be opened in the constructor of the fstream object. If it doesn't, you need to open it yourself.

Oh give him a break, it's for a christian camp after all

[parksie]

LOL I thought it was for someone called Christian Camp

Either way it's religious brainwashing and I won't stand for it

[prog_tom]

What do you mean Christian Camp? I said Christmas Camp

That's what you wrote

Anyway, did it fix your problem?

[Earl of Gonds]

i once knew a guy named christian camp, he was catholic though

[Stefan Raab]

was he a brutha too?

[prog_tom]

I solved it myself... I put a getline and a messagebox in the while(!FILE.eof()){}
Thanks anyway, do you know how to set the text of a label, button, and a edit during Runtime? For instance, I press Button1 and Text1's Text will change to : "sex!"

[abdul]

There is a function to do so. You can always look up at MSDN for the API refrence.
The function is called:

SetWindowText()

and at takes two parameters so if you have a handle to the button, textbox, label..etc, then you can use the similiar code

SetWindowText(THE_HANDLE, "Is sex fun?");
