Dll object questions.

Hello.

In the Dll Object Argument is the same that Parameter?.

I know an fuction in the library "User32.dll" the function is called "GetSystemMetrics" these function have an PARAMETER called "SM_CMOUSEBUTTONS" that return the number of buttons of the mouse.
I try to work with these options in MMF2 but nothing happens.

Somebody can help me to solve theses cuestions?

Thanks.

What you have to do, for example :

Load "user32.dll"
Add Integer Argument 43
Set Counter to ReturnInt( "DLL Object", "GetSystemMetrics")

(the value of SM_CMOUSEBUTTONS is 43)

Sorry I don't understanding your reply.

I only need retrieve the numbers of Mouse Buttons in any PC run under Windows that execute my aplication.

Why 43?

Is the same PARAMETER that ARGUMENT?, and how manage PARAMETER in the DLLobject in MMF2?.

I think that the value of SM_CMOUSEBUTTONS is the number of mouse buttons, then because your value of SM_CMOUSEBUTTONS is 43.

Waiting your works...
Sorry and thanks.

You call GetSystemMetrics with a number of what system metric you want to know.
43 is the constant who tells GetSystemMetrics to retrieve the number of mouse buttons.
