I want to convert that C++ to autoit.

Questions:

1)How to convert GetSecurityInfo and SetSecurityInfo to autoit.

2)_WinAPI_OpenProcess(WRITE_DAC, 0, $pid); what's WRITE_DAC? MS says it's 0x00040000L. but what does that L mean at then can I just use 0x00040000?

3) if function argument is &secdesc then do I have to use $secdesc or ByRef $secdesc?

4)how to convert DACL_SECURITY_INFORMATION | UNPROTECTED_DACL_SECURITY_INFORMATION to autoit? MSDN gives values for these variables but what I need to do with | ?

5)What is ERROR_SUCCESS in autoit

1)How to convert GetSecurityInfo and SetSecurityInfo to autoit.

No idea. But I think DLLCall with Advapi32.dll could work if nothing else does...

2)_WinAPI_OpenProcess(WRITE_DAC, 0, $pid); what's WRITE_DAC? MS says it's 0x00040000L. but what does that L mean at then can I just use 0x00040000?

Google says something about the suffix L/l being a long or something...

3) if function argument is &secdesc then do I have to use $secdesc or ByRef $secdesc?

From what I understand ByRef...

4)how to convert DACL_SECURITY_INFORMATION | UNPROTECTED_DACL_SECURITY_INFORMATION to autoit? MSDN gives values for these variables but what I need to do with | ?

Bitwise OR

Interesting how I came up with all of those answers using google. Also your code is missing pretty much everything to even start to attempting to make it work...

Cheers.

Here's my new code. How many mistakes can you still find from it?

Did I convert variables right?

Does this code have anything else than GetSecurityInfo and SetSecurityInfo missing?

Func   openSecureProcess($Class,$Rights)
      Local $pid;
      Local $window;
      Local $process;
      Local $dacl;

$SE_KERNEL_OBJECT = 6
$DACL_SECURITY_INFORMATION = 0x00000004

GetSecurityInfo? SetSecurityInfo What is that?

Also you are missing #include...

How do I complete these 2 funcs?

Func GetSecurityInfo($handle, $ObjectType, $SecurityInfo, $ppsidOwner, $ppsidGroup, $ppDacl, $ppSacl, $ppSecurityDescriptor)
    DllCall("Advapi32.dll", "long", "GetSecurityInfo", "HANDLE", $handle
EndFunc

Func SetSecurityInfo($handle, $ObjectType, $SecurityInfo, $psidOwner, $psidGroup, $pDacl, $pSacl)
    DllCall("Advapi32.dll", "long", "SetSecurityInfo", "HANDLE",$handle
EndFunc

http://msdn.microsoft.com/en-us/library/aa379588%28VS.85%29.aspx sais that 2nd argument is ObjectType. but when I looked at DllCall I didn't find "ObjectType" from valid types list.

I found Optional output arguments can be NULL but what does NULL mean? just ""?

Does [out, optional] mean that I have to put ByRef before variable?

Sorry for so many stupid questions about DLL, I have never done anything like that before.
