Nomadmemory + loop with while

[NandaS]

Hi to everybody!

I'm trying to do a loop cheking a memory state... while this memory is 0, just sleep. Something like that:

Global $i = _MemoryOpen(0x005F7FEC, $Open); this memory could be only 0 or 1
while $i = 0
Sleep (100)
wend
and here goes the code...

How can I check this memory state in a loop? I want that goes out of the loop when this memory get the state 1.

Thanks

Put the memory checking line inside the While loop, otherwise it's only checked once and your loop never exits.

[NandaS]

While $i = 0
   Sleep(100)
   $i = _MemoryRead(0x005F7FEC, $Abrir)
If $i > 0 Then
   ExitLoop
EndIf
wEnd

I just imagined something like that, but it this is not exiting the loop =p

There's no need for the If then checking, if $i <> 0 it's going to exit the loop. I'd guess that whatever _MemoryRead is reading, it's always returning 0.

There is the problem... if i do that:

While $i = 0  
Sleep(100)  
$i = _MemoryRead(0x005F7FEC, $Abrir)
wEnd

It would read the memory every time that is looping, and when it becames different from 0 than exits the loop.

But here this only exits the loop when the memory returns 1 and the program is executed twice. Crazy things happens

You used _MemoryOpen in the first example script and _MemoryRead in the others, are you sure you're using the correct function? Also, I thought you wanted the loop to exit when $i was not 0.

By the way, your method using the If Then statement still reads the memory every time through the loop, and will exit the loop if $i is > 0, which is almost the same as using While $i=0 except your check will only exit the loop if $i is 1 or more, not if it returns -1 or less. If the memory read only returns 1 or 0 that's not a problem, if it ever returns

EDIT: Noticed that the forum software screwed with some symbols.

Why not:

While 1
If ((_MemoryRead(0x005F7FEC, $Abrir) <> 0) Then ExitLoop
Sleep(100)
EndIf

or

While ((_MemoryRead(0x005F7FEC, $Abrir) = 0)
Sleep(100)
EndIf

Unless you need $i elsewhere?

Alright, it the 1st example you have _MemoryOpen, but in other you do not anymore.

What I suggest is you read through Nomads Memory Function descriptions.

What you need to do is:

local $PID = ProcessExists("ProgramName_to_ReadMemoryFrom") ;get the PID
local $MemoryHandle = _MemoryOpen($PID) ;open the memory

while _MemoryRead(0x00123ABC, $MemoryHandle) = False ;while memory read from the location is 0
   sleep(100)
wend

Also, the address can change everytime you run the program that you want to read from. Not sure what you are reading from, but you need a base address and an offset, or if you are reading from something more complicated you will need to read pointers.
