Bit Blit? Memory problem

What I have

Tile based game
64 pixel tiles, RGB color
maps that are changeable and variable in size

:confused: Problem:

Maps over 80 x 80 will not appear on the screen
Chemist not programmer
Slow brain

Thoughts:

I think its a memory thing but I am not sure.
Is keeping that big DC in memory really really bad?
I dont ever display the whole DC just what you see.

Also, if I change the picture in the DC does it create a memory
hole or pointer problem. I mean without deleting it.....

Thanks

in the early stages of my rpg engine i did the same thing as you, and realized the same thing~! so all you need to do to work around that problem is ONLY draw onto your backbuffer what you need to see on the screen at the moment! it takes a bit more thinking, but it wont take too much effort to adjust your code.

Blit your map on an invisible picbox, then copy (or "flip") that picbox to the end result picbox!

OK
those will work but what is the problem?
Why will the map not display...
Am I loosing memory?

More Explenation:
When I create the maps I blit the hexes one at a time in rows and cols. with every other column offset (hexes). I do this all in my backbuffer.

I then display only what is required from the backbuffer to the
display. Like I said it works for maps of up to 80 * 80 hexes but
not for larger ones.

Well

I am scrolling the map with a picture box behind the form, all of
the map data like player positions and hex type is stored a
data array. When the player moves from hex to hex it just
checks the array to find out whats there. The players are sepetate.... Thought this was efficiet.... guess I will have to
change it.

Scrolling offset hexes will be a pain in the but :(
Time to program....
