Title: Buffer overrun when loading image
Post by: Devil0150 on August 25, 2009, 01:35:28 pm

Code: [Select]

Piece::Piece()
{
imgPiece.LoadFromFile("C://Documents And Settings//User//My Documents//My Pictures//piece.bmp");
sprPiece.SetImage(imgPiece);
}

I am using visual c++ 2008 and when I start the program I get a buffer overrun on the this line:

Code: [Select]

imgPiece.LoadFromFile("C://Documents And Settings//User//My Documents//My Pictures//piece.bmp");

I even tried \\ instead of //. It still doesnt work.

What did I do wrong?
Did I miss something on the tutorials?

// is for comment
If you want to write '/' you only need to write '/'. If you want to write '\' you have to write '\\'.

Does your code compile ? It should not.

This is wrong in some cases, sorry.

Inside double quotes / and // is the same. The text doesnt get green (comment color) even if I use //. And Yes, the Code compiles.

// is for comment

// isn't a comment when it's inside a string.

Why not? String literals aren't checked at compile time.

No, it is definitively not the same. Accordingly, your path containing double slashes is invalid.

What do you exactly mean with "buffer overrun"? Which buffer is overrunning? What error message do you get?

I meant none of them makes the text a comment. The error message says:

Code: [Select]

A buffer overrun has occurred in Program.exe which has corrupted the program's internal state. Press Break to debug the program or Continue to terminate the program.

For more details please see Help topic 'How to debug Buffer Overrun Issues'.

But I fixed it. It happened because the first time I compiled the code, I got some warnings. And I tried to remove them by removing the -d from the stuff I put in the Linker. The warnings were removed but thats when the buffer error started to show. Now that I put the -d, the buffer overrun error doesnt happen anymore.
