user32.dll call API function

[在水一方]

user32.dll          API function: mouse_event

for example:
Public Const MOUSEEVENTF_LEFTDOWN = &H2
Public Declare Function SetCursorPos Lib "user32" (ByVal x As Long, ByVal y As Long) As Long
Private Sub Timer1_Timer()

SetCursorPos 300, 20
mouse_event MOUSEEVENTF_LEFTDOWN, 0&, 0&, 0&, 0&
End Sub

How can I use "call library function node" in labview to realize "mouse_event"

Thanks!

This can be found in quite a few places in this site (example) and is actually a fairly simple call. The numbers for the flags come from the header file where the definitions are made.

More information on working with DLLs can be found here.

To learn more about LabVIEW, I suggest you try searching this site and google for LabVIEW tutorials. Here and here are a couple you can start with. You can also contact your local NI office and join one of their courses.
In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf).
