Olly assembler and disassembler for visual basic DLL library

http://sandsprite.com/CodeStuff/olly_dll.html

this is where i found what i was looking for to assemble instructions to proper machine op codes......... it assembles instructions and disassemles them as well......

[goldbaby]

here is a little program that assembles a big instruction into proper machine opcodes.....

Code: Select all

Structure t_asmmodel; {    // Model To search For assembler command 
    code.c[15];     // Binary code 
    mask.c[15];     // Mask for binary code (0: bit ignored) 
    length.i;                // Length of code, bytes (0: empty) 
    jmpsize.i;               // Offset size if relative jump 
    jmpoffset.i;             // Offset relative to IP 
    jmppos.i;                // Position of jump offset in command 
EndStructure
Global cnn.t_asmmodel
txt$=Space(85)
ttt$="test word ptr cs:[00404706], 0004"+Chr(0)

l=OpenLibrary(#PB_Any,"olly.dll")
If l

*tas=GetFunction(l,"Assemble")
offsett=$1000
asmlen=CallFunctionFast(*tas,@ttt$,offsett,cnn,0,0,@txt$)


t=0
While t<asmlen
tl$=tl$+Hex(cnn\code[t])+"  "
t+1

MessageRequester("machine opcodes in hex of assembler instruction TEST WORD PTR CS:[00404706], 0004",tl$)
EndIf
