pda An unknown error occurred

[surikids]

Hello guys.

 I am new to LABVIEW PDA MODULE application.

 My LABVIEW version is 7.1 plus its PDA module.

 However, I cannot compile even the example file, and it shows

 An unknown error occurred.  Please contact National Instruments for more help.

Do anyone knows the solution? Or I miss some installation?

Hello

Are you using the PDA module for Pocket PC or the PDA module for Palm OS?

I'm assuming the Pocket PC version, in which case did you install the Microsoft Tools that are required by the PDA module in order to create applications that will run on the PDA? And if so what was the installation order that you used?

These need to be installed before you install the PDA module software. So the installation order for the software should be : - LabVIEW 7.1; then you will need to install the Microsoft Tools in the order as described in the LabVIEW PDA module's readme file (which I've attached below); then install the LabVIEW 7.1 PDA module.

Take a look at the following knowledge base entry which gives details of where you can find these tools, look on the list for LabVIEW 7.1

If this isn't the issue, then can you take a screen shot of the error message that you are getting and post this onto the forums?

Hello:

   Thx for the reply. I am using the Pocket PC version.

   I reinstall LABVIEW and PDA module as u said, and it works.

  But the other problem comes.

  It is :

   Error downloading. The application may not have been sent.

  This problem occurs both in example and the VI I created.

  I thought it might be the install or configure problem. So can u please help me to find it out.

  Thx.

I think I need to clarify my problem:

I can create the exe file for PDA, but after that, I cannot download it into PDA or run it in emulator.

When I try to do so, the error shows as is described above and my PDA do not has any response.

I am wondering how can I test if my VI really works.

I've seen that before, and sometimes recompiling it for PocketPC 2003 instead of Windows Mobile has helped me. Also, if your PDA has a memory card, you can simply copy the .exe to that and run the application from the memory card.

Good luck!

THx. I did copy the file into my PDA, but the exe do not run as I expected. I wanna check it and debug it via emulator or via cradle. The problem is it always appear the error message as described above:

Error downloading. The application may not have been sent.

Can anyone tell me how to debug it!!!!!

THx.

Hai,

The problem with PDA can be solved by step by step troubleshooting one at a time.

1. Place the PDA in cradle mode couple it with microsoft active sync see if it connects perfectly to the host pc.

2. assign the ip address and subnet mask thats matching to the pc and establish a remote desktop connection.  The procedure for establishing the desktop connection can be found along with the help manual (pdf) that ships with the pda module.

3.When the remote desktop connection is done then try downloading a simplest application.

if you would like to debug the code in emulator mode then you must change some settings in boot.txt. 

When you try to switch to emulator mode you will encounter an error since windows blocks its execution.  The error can be resolved by checking out the error in microsoft.com that will guide you to change the boot.txt and you can proceed with emulator mode.

I was too struck with similar problems but came out with step by step troubleshooting. 

All the best

With best regards,

JK

Hey surikid,

Can you post your code, or a sample of it, for others to look at? There might be something in there that other people have had trouble with. Also, I've found it helpful to include the same VI as a Windows Target  in the Project Explorer for testing and debugging the logic of my programs. Its faster to debug the logical sequencing in Windows, and then use the PDA for final testing.
