call dll's function

[Vincent Chollet]

In order to call dll's functions in a program, written in graphical
programming langage (labview), I would like to understand the arguments
of these functions.

How can I know, or where can I find the values of the dll's functions
arguments ?

For exemple, play a midi file with mciSendString of winmm.dll.

You need documentation for your dll.

May be you can find docs for standart Windows API function in help for
Borland C++, or Visual C++.
