try:

mov eax, ADDR Ipbuffer
mov IPbufferADDR, eax

or

lea eax, Ipbuffer
mov IPbufferADDR, eax

or even

mov eax, OFFSET Ipbuffer
mov IPbufferADDR, eax

:)

I wanted to say thanks, the last 2 of strykers meathods work, and so did Ernie's. (I played with them all to see) and thanks Ernie for explaining why ADDR wouldn't work. I truly apreciate you're help. While Researching LEA to find out what it did/why it worked. I rediscovered something that I never knew I missed so much. Opcodes.HLP :)
After Getting the Pointer I needed. I wrote this;


mov ecx,0
mov eax,OFFSET Ipbuffer
mov IPbufferADDR,eax

mov eax,IPbufferADDR
mov IPbufferADDRtmp,eax

Search:
mov eax,
inc ecx
.IF ecx>=3000
jmp EndSearch
.ENDIF
.IF eax==0ffffffffh ;StartBlockIndicator
add IPbufferADDRtmp,10h
mov eax,
.IF eax==0ffffffffh ;Verification of Start block
mov eax,IPbufferADDRtmp
mov StartBlockADDR,eax
invoke wsprintf,ADDR StartBlockADDRString,ADDR DecimalFormat,StartBlockADDR
invoke MessageBox,0,addr StartBlockADDRString,ADDR StartBlockADDRString,MB_OK

.ELSE
sub IPbufferADDRtmp,10h
.ENDIF
.ELSE
add IPbufferADDRtmp,01h
jmp Search
.ENDIF
EndSearch:
ret
SearchBuffer endp

Is that how a Search should be done?

Uhh! But if your going to search something in a byte stream, you have to do something like this:

For example:

string - zvvvvvvvahhh

letter to find - a

First you have to load the address of the string...like this
lea esi, str
then scan until you hit a null pointer

xor ecx, ecx

@@:

  mov al, BYTE PTR [esi+ecx]

  or al, al

  jz @F

  cmp al, 'S'

  je @F

  inc ecx

  jmp @B

Since I don't know what kind of data are you going to search, I can't think of any ideas apart from these. Just remember if you want to search on something you need the address of the source then start searching from there.

Hmm! I retraced your code and everythings fine except I don't have that game you specified to read the memory from. Too bad, I don't have any experience on reading other processes memory :(. Maybe someone can help you who has experience this. As far as I can go this is where I'll stop. :(

Maybe these guidelines will help:
1. Since you said your searching for a string. Are you sure your string search algorithm works fine.
2. Maybe the memory you specified to read in, is located on other parts in memory.
