Reading numbers from text file

[MichaelW]

What is better to use HeapAlloc or GlobalAlloc?

For what you are doing I think the best choice is the one that is easier to use, and the same for the functions to open and read the file.

So new question. I have a struct of three dword elements, I have a block of memory size of this struct and for example variable first of this struct. What I need is to replace my "first" by new one.The solution I see is:

Code Select Expand


invoke HeapAlloc, heapHandle, HEAP_ZERO_MEMORY, sizeof Element
mov pointer, eax
lea ebx, first
mov [ebx], [pointer]
mov [ebx + 4], [pointer + 4]
mov [ebx + 8]. [pointer + 8]

Is there a easier way of doing this? I know it won't work but I only wanted to show sketch. And for question why I need it for:  I'm implementing doubly linkedlist and I need it to "insert" method.

Hi,

   Look at the MOVe String command.  REP MOVSD will simplify
the transfer, but it requires more setup and the index registers.

Use structures for the linked list (more readable). e.g.:

Code Select Expand

NODE struct
flink PVOID ?
blink PVOID ?
data DWORD 4 dup (?)
NODE ends

mov ebx, first ; first = ptr NODE

invoke HeapAlloc,...
mov edx,[ebx].NODE.flink
mov [ebx].NODE.flink,eax
mov [eax].NODE.blink,ebx
mov [eax].NODE.flink,edx
.if edx
mov [edx].NODE.blink,eax
.endif
mov [eax].NODE.data[0],...
mov [eax].NODE.data[4],...

It worked quite well, thanks.
