Hi! I''m using the function CreateDIBSection to create a fast bitmap buffer. This function gives me a void-pointer to the memory where the bitmap is located. But how can I access this memory? It''s a void pointer and I need a BYTE-pointer or something like this. Can the void pointer be converted to a BYTE-pointer so that I can change the pixels of the bitmap? Can anyone please help me, it''s quite important for me to know that. Thank you very much in advance. cu LaBasX2

Hi there !
Perhaps try it like that :

void *p1; char *p2;
.
.
.
p2=(char*)p1;

Hmm... from what I remember, you can re-cast the void pointer as a BYTE pointer or whatever... or you can use it along with memcpy to copy parts of the bitmap into an array (slow), or even have an array pointing to the buffer memory by assigning it to the void pointer (haven''t practiced C in a while, must be something like *array[]=pointer).

Sorry if these are short and vague answers, but that was in order to give you a quick reply so you know what to look for

Hope this helps,
Lamtd.
