DllStructCreate()

[buzz44]

Im trying to create the below DEVMODE structure, and seeing as this is kind of my first DllStruct script I'm not sure about this stuff.

I think I have done most of it correctly but I don't have any idea what to put for"String * 32" and "LONG" for DllStruct as it doesn't support those types, actaully it most probably does but I don't know the correct word type for it. If someone could please take a look at the msdn link below and check that I'm creating this structure correctly I would much appreciate it.

FYI: I'm trying to change access the ChangeDisplaySettings function, if someone has already done this please don't post it , I would like to figure most of it out for myself.

Thanks.

IMO the struct doesnt look right.

the one on MSDN has sub-struct's.

and yours doesnt.

The one from MSDN also looks alot longer...

but i think "STRING * 32" = "char[32]"

and "LONG" = "int"

@Larry

I did ask people not to post it if they have it lol, but anyway I will look over your code and attempt to learn , thanks.

@w0uter

Thanks for info, I am now changing the structure.

Larry, I don't understand how you created your structure, and it worked lol.

ie.

$DEVMODE = DLLStructCreate("byte[32];int[10];byte[32];int[6]")

Where my now 'modifed' structure looks like...

$DevMode = DllStructCreate("char[32] _
                        ;int _
                        ;int _
                        ;int _
                        ;int _
                        ;dword _
                        ;short _
                        ;short _
                        ;short _
                        ;short _
                        ;short _
                        ;short _
                        ;short _
                        ;short _
                        ;short _
                        ;short _
                        ;short _
                        ;short _
                        ;short _
                        ;byte[32] _
                        ;int _
                        ;dword _
                        ;dword _
                        ;dword _
                        ;dword _
                        ;dword _
                        ;dword")

I am currently pondering how you figured out your's and got it to work whilst looking at the structure tree at msdn, as w0uter said it has sub-structure's etc. Would you care to enlighten me please?

Ok last thing, with...

$DEVMODE = DLLStructCreate("byte[32];int[10];byte[32];int[6]")

Does the int[6] = dmFields? If so is it because [6] is the 6th 'thing' of the structure and its 'int' because its a 'dword'?

Also why is it byte[32]?

Thanks again.

[] is an array
