Title: How do you store an address in a register? [Solved]
Post by: lonewolff on March 08, 2009, 01:47:25 AM

Hi there,

I am wondering how I can load a register with a pointer to some text. I want to display certain text given certain conditions.
Here is what I have. I think I am close, but it wont compile.

Code Select


.data 
TextCondition1		db "Condition 1",0 
MsgBoxCaption		db "Information",0

.code 
start:

mov [ebx],TextCondition1

invoke MessageBox,NULL,ebx,addr MsgBoxCaption,MB_ICONINFORMATION
invoke ExitProcess,NULL 

end start

The problem is at the mov [ebx],TextCondition1 line.

Any guidance would be much appreciated. :bg

Code Select

mov ebx,OFFSET TextCondition1
Less common:

Code Select

lea ebx,[TextCondition1]

Excellent. That is exactly what I was after. :8)

I'll have to look up my opcodes to see what LEA does.

Thanks for your help.
