Hi, For instance Im writing DLL and in this DLL I'll read the data in from a file and draw the data into memory and transfer into the picture box. Then from time to time juz update the picture box image with the image that store in the memory.

My problem is how to hold the image in memory after I complete one function in the DLL. 'Coz when I exit the function, this memory will release rite?

regards,
Chris.C
