Calling User32 EnumPropsEx Properly

Recommended Posts

Bilgus

So first things first the example in the help file for _WinApi_Enum_Windows has an error

;_ArrayDisplay($aResult, "_WinAPI_EnumWindows", Default, Default, Default, Default, "#|Handle|Class|Title|Text|Process")
  Should Be
  _ArrayDisplay($aResult, "_WinAPI_EnumWindows", Default, Default, Default, "Handle|Class|Title|Text|Process")

Next is a bit of helpful info on LPCSTR in a callback function it needs  to be passed as a PTR

DllCallbackRegister($sFUNCT, $sRETURN, "ptr")

Finally on to my question

I'd want to call EnumPropsEX and pass a string through lparam + append to it rather than declaring anything globally

I can Come up with two ways to do this The second it a lot more code but possibly safer but the first way I think Should do

1. From a bit of testing It seems AutoIt won't overflow a DllStruct?

2. Are strings passed through DLL call guaranteed to be 'an ANSI string (a minimum of 65536 chars is allocated)' as the Helpfile clearly states?

#include <Array.au3>
#include <WinAPI.au3>

      Hello,
       
      I'm trying to figure out how to add attributes to a Credentials Store.  I have been using it to store Creds and I was using the Comments to store some limited data but I'd really like to start using the 64 possible Attributes so I don't need to use the Registry to store misc information my script needs.
       
      I have been trying to figure this our for a few days now and I'm able to create the structure, but it fails with Invalid Parameter when trying to add the item to the store.
       
      Any ideas or pointers to where to get some further information on this?
      Thanks,
      Mike

      I've been working with the Windows Credentials store to store credentials for lots of RDP connections.  I'm also using this code in other scripts to store and retrieve "legacy" credentials for my scripts that have a Save Password checkbox.
      All goes well, until someone requests a button to display a list of all saved credentials.  I found the CredEnumerate call and it looks like it's working but the Target and UserName field that I want is stored inside an array of pointers and I can't figure out how to get data from inside that.  I found a post from 2009 that talks about this, but there was never a solution.
       
      Below are my functions put into an example script.  the _Credentials_Enumerate() is where i'm having problems.   Anybody have some ideas?
      Thanks,
