C++ error: "Unhandled exception at" Visual Studio

[Vortex]

Unhandled exception at 0x6812851a in Editor.exe: 0xC0000005: Access violation reading location 0x0000323c.
when i try to run my program ( level editor ) from visual studio i get this error,
i have no idea how to fix this,

all info i can give is that it stops execution and show me this line of code
SDL_FillRect( screen, &screen->clip_rect, SDL_MapRGB( screen->format, 0xFF, 0xFF, 0xFF ) );

i dont see anything wrong with it and when i remove it it just sais the error is in another line of code,

Have you tried running it with a debugger?

[Vortex]

i run it with debug mode in visual studio if thats what you mean?

[Bludklok]

We need some more source code...

Btw double check to make sure you declared all of the variables you are trying to use. (Make sure they have values and what not)

[Vortex]

since i didint know what was wrong in the code i just uploaded all,
its mostly copied functions from lazy foo so thoose functions should be working i think

With a debugger you can step through your program linewise and get other useful information. It's not running the program in debug mode, but debug mode is important for the debugger to work correctly.

is there a debugger in visual studio? how do i use it?
any other anwsers on my problem?

Yes, there's a debugger in Visual Studio. There should be a tab up top with all your debug tools.

This won't help your current problem, but a small tip...

Code: Select all

SDL_FillRect(screen, NULL, SDL_MapRGB(screen->format, 0xFF, 0xFF, 0xFF));

...will fill the entire surface, in your case, the whole screen.

yeah, i dont see anything wrong with that line? ive tryed to remove it but i still get the error?
any hints?

[Bakkon]

Only thing I can think of is you didn't use SDL_SetVideoMode on the screen. We can't do much more for you without seeing some source or given better detail on the error.

Not much use missing half of the files ( test.map, tileSheet.png, project file ).

[Vortex]

the map file is supposed to be generated by the editor.

tile sheet. not so high class but im actually proud for being the first tile like thing i ever drawn

Compiles and runs fine for me in Code::Blocks. Not sure what's up.
