Call mode of dlls

[JScript]

I realized that some parameters of the dlls have changed, eg:

CreateDIBSection before:

DllCall('gdi32.dll', _
        'ptr', 'CreateDIBSection', _
        'hwnd', 0, _
        'ptr', DllStructGetPtr($tBITMAPINFO), _
        'uint', 0, _
        'ptr*', 0, _
        'ptr', 0, _
        'uint', 0)

After:

DllCall('gdi32.dll', _
        'handle', 'CreateDIBSection', _
        'handle', 0, _
        'struct*', $tBITMAPINFO, _
        'uint', 0, _
        'ptr*', 0, _
        'handle', 0, _
        'dword', 0)

Any particular reason for this? Although in both modes it works normally...

Technically they are the same thing. Both are pointers to struct but one is explicitly labeled as a pointer to struct instead of just a pointer. At the business end, the pointer is just a number and works the same both ways.

Ok, now I understand better, thanks!

So AutoIt externally references it's structs by pointers, or does it convert the internal "handle" into a real one?

That is internal behavior and unimportant for you as an AutoIt user. I can't answer the question as AutoIt is closed source.

Let's wait for a dev to come along then.

handle and ptr do the same just easy way to use them when MSDN API use one or the other.
