Calling external app / code on PPC

[philips]

Again demonstrating my ignorance...

I am using a mapping app on a PDA called OziExplorerCE.

THis comes with a simple API which I would like to use from LabVIEW - you can look at it here

http://64.71.184.220/ozice/ozice_api_docs.html

All I need to do is

1. Write data to a text file (easy - even I can do that!)

2. "Send a message to OziExplorer with the correct command number to do the Command"

An example of this from VB is:

Result = SendMessage(OziWindow, WM_USER + 5, Me.hwnd, 101)

How can I do this from LV PDA 7.1?

I had a look at an example on the NI site here:

http://sine.ni.com/apps/we/niepd_web_displ...source=External

This uses a Call Library Function Node which appears simple, but it appears to need a whole heap of complexity with the DLL & Visual c++ code associated with it.

Is it really this complicated?

Is there a simple way of doing it?

Any pointers greatfully received.

Cheers,

Phil
