Unable to create PDA application (version 8.2) - Unknown Error

[sstolteq]

Hi,

I am trying to create a touch-screen keypad VI where a user can enter a number. This keypad will be a part of my much bigger user-interface application. I am using Pocket PC 2003 SE emulator (PDA module version 8.2) to test this VI. There are no broken wires or broken run button. If I run this VI for PC as a target it just works fine..but it gives an error: "unable to create file" when I try to build it as an application for the PDA emulator. Attached is the VI - Popup keyPAD.vi and also a text file - BuildReport.txt (this file is created after I get the above error).

Any help would be much appreciated.

PS: Please save the VI "KBDriver.vi" in the same folder where you will save PopupkeyPAD.vi.

I figured out that having the application control function STOP in PopUpKeyPAD.vi has to do something with it. I had no problem building into PDA application when I removed the STOP function from my VI !!!

Hi sstolteq,

I am investigating this issue. I can see the Stop function has nothing to do with it. I will be creating my own VI to see where exactly the error occurs. If you have any suggestions/comments, please be sure to let me know.

Hi Adnan,

Can you figure out anything from the error report that is generated? For some reason, I do not get this error after removing the STOP function from my VI..but I do not understand why. I have tried looking on the web for the same but haven't got any relevant information till now.

Any help would be much appreciated.

Hi Shruti,

I hope you are doing well today! I have filed a CAR (ID# 46CA61GF) for this issue. Seems like its a rare issue with the C Code Generator. I hope your workaround is sufficient for your programming right now.

There is a building error that's somehow triggerred by the STOP function, but the error is not related to the STOP function. It is caused by an unwired boolean in a sequence frame. The workaround is to wire the boolean to the sequence tunnel. See image below.

Thank you, Miko 🙂

But I still wonder why the unwired boolean gives an error - there is no error running the same VI on a PC !

It's a bug in the PDA Module. We'll fix it in the next version 🙂

Hi Miko,

Would you be knowing about the VISA error -1073807343?

I am trying to talk to the serial ports of my Single Board Computer (SBC) using PDA module's VISA functions. Using tools like Hyperterminal, I have checked that the three serial ports of SBC are working correctly. But I am unable to use VISA to open/configure/talk to any of these serial ports.

Earlier, I was getting error code -1073807202 when trying to open a port. After reinstalling VISA on the SBC I do not get this error. But now I get error -1073807343. VISA: (Hex 0xBFFF0011) Insufficeint location information or the device or resource is not present in the system.

Please see my attached VIs: V-open.vi and Vtest1.vi. The first VI, V-open.vi, simply tries to open a COM PORT (I have tried opening different COM PORTs). The second one, Vtest1.vi, waits for a user to change the value of a VISA Resource name control and then tries to read its properties. While V-open.vi gives me the above mentioned error, the second VI is behaving very different. After converting Vtest1.vi to an application I do not see  the VISA Resource name control on the front panel..it just disappears. The same happens in the emulator too.

I would very much appreciate your help,

Shruti
