i:dword;
offsets:cefuncproc.pDwordarray;
a:dword;
begin
if checkbox6.checked then
begin
baseaddress:=($00642818);
offsetcount:=1;
offsets[i]:=($274);
ce_getaddressfrompointer(baseaddress,offsetcount,offsets);
label1.caption:=inttostr(a);
address:=(a);
size:=4;
ce_freezemem(address,size);
maxid:=fzid1 ;
label1.caption:=inttostr(fzid1);
end
else
begin
ce_unfreezemem(fzid1);
label1.Caption:='sucess';
end;

you're forgetting to allocate memory for the offsets array and initializing i (or in this case replace it with 0)
so at least before the line: offsets[i]:=$274; have the code:
| Code: |
setlength(offsets,1);
i:=0;
|
and you're also forgetting to set a.
should be:
| Code: |
a:=ce_getaddressfrompointer(baseaddress,offsetcount,offsets);
|
same goes for fzid, should be:
| Code: |
ce_freezemem(address,size);
|
and fzid has to be declared globally or at least inside the TTrainer object. Not inside the current function since that variable gets destroyed as soon as you exit the function

after the modifications recomended by you,theres still errors
---------------------------
ProjectX
---------------------------
Access violation at address 004F238F in module 'ProjectX.exe'. Write of address 00000000.
---------------------------
OK
---------------------------
but with
| Code: | | a:=ce_getaddressfrompointer(baseaddress,offsetcount,offsets); |
and
| Code: | | fzid1:=ce_freezemem(address,size); |
commented
it wont show errors,i also put the array directly instead of declearing I=0
offsets[0]:=$274;
since setlength will generate a imcopatible type error
PS:this is my first time working with arrays

simillarly to changing registers i tried to use the same idea on AA
1stly i tried to use the plugin exports part
i try it with this code
| Code: | procedure TTrainer.CheckBox4Click(Sender: TObject);
var script: tstringlist;
s:pchar;
begin
if checkbox4.checked then
begin
script:=tstringlist.create;
with script do
begin
add('code...');
add('code...');
autoassemble(script,false);
script.free;
end
end
else
script:=tstringlist.create;
with fscript do
begin
add('code...');
add('code...');
autoassemble(script,false);
script.free;
end;
end; |
the code executed and works like i want it to be but returned with this
---------------------------
ProjectX
---------------------------
Access violation at address 00506508 in module 'ProjectX.exe'. Read of address 000003A0.
---------------------------
OK
---------------------------

no idea, it should work (assuming you included the autoassembler unit to the uses), looks like a property of a undeclared (nil) object is being accessed
Is this code execute before the symbolhandler is initialized ? (usually happens in oncreate iof mainform)

script:=tstringlist.create;
with fscript do
begin
add('code...');
add('code...');
autoassemble(script,false);
script.free;
end; |
