Hello

For me it is just a preference.

If you want to read sth about local variables vs. property node, please look at

http://digital.ni.com/public.nsf/3efedde43...47?OpenDocument

BTW there was such topic on Programming Discussions > General - "Local Variables or Property Node"

Cheers

Hello

It is crudely way but it is simple and works (... instead of local variable i'd prefer value property node Somehow I don't like to use local variables .

Thanks for idea,

Peter

Hello

I've got a tiny problem with 'String Control'.

How can I limit the width of text which user can write in 'String Control'?

Many thanks,

Peter

I've forgotten add one file that is needed during compile process: OW.Interface.vb link: http://docs.talk1wire.com/vb.net/OWInterface_vb.html

Hi

This was one of another idea from my solution list , but thank you.

Another example of something like that (web browser in ActiveX container):

hi once again me now I realized that the simplest way is to use DataSocket with specific http url and receive the html page. Next step is to use XML parser and after that I'm at home.

My request has still active status.

Hello

I've got a little communication problem with the device (HA7Net) that I bought last week. HA7Net is 1-wire <--> Ethernet converter. In my project it acts as a bus master in network which includes temperature sensors. Communication between the converter and PC is through http protocol. In a test stage I used simply web browser (wget)and of course it works. And now there is a time to write some VI. I've got few ideas how to solve this but the simplest is - use the ready functions that are developed. And now there is a problem. These functions are written in Visual Basic and .NET platform. I've never used VB, even haven't got someone to help me to compile this routine into dll.

Could anybody compile the file into dll which will work in LV? My operating system is Windows XP (SP1) and LabView versions are: 6.1 and 7.1.

Original link to HA7Net VB functions is : http://docs.talk1wire.com/vb.net/HA7Net.html - Section File: HA7Net.vb

Also I send VB .Net file with these functions (copied from that web page).

Thank you very much.

Peter

It sounds like you found a solution. Another way is to create the file in the c program and then have lv check for the presence of the file. When LV toggles the boolean then have lv delete the file. Repeat this process. This way you can have the c program verify that LV saw the file and toggled the boolean. As you say, NOT pretty but works. Why not get LV to do the DAQ card directly?

Hello

I think that the right solution for your problem is DDE (Dynamic Data Exchange). With it you can communicate with multiple applications on the same computer.

It's quite easy to implement DDE in C and LV.

You can find DDE libraries in : "c:\....\National Instruments\LabView X.X\vi.ib\platform\dde.llb".

Please look at http://www.stoff.pl/ . There is satellite tracking system for radio amateur and obsering purposes (Orbitron). In this programme was included DDE Server which allows you receive tracking data in your application. In download section you can find example (in Delphi) "My DDE Client".

I sent:

- LV routine (dde_client);

- pdf (briefly describe the Dynamic Data Exchange in LV).

If you want to use Orbitron and LV, please remember to do one modification in configuration file "c:\...\Orbitron\Config\Drivers.dat" - just add one line at the end, for example LabView. Now you can enable DDE Server in Orbitron (rotor section).
