I am seeking information.

Has anyone in the OI world put OI on a PDA or sometype of hand held computer? I need to gather information on a small hand held unit then transfer it to a main computer for processing.

Thanks,

Jeff

You can EMail @ [email protected] if you would like to.

thanks

We have tried a little, with our desktop app.

You can get a Terminal Server client for the PDA and run you application from there, provided you have Win2000 server.

I suspect there are Citrix versions too, and probably more.

You obviously need to have allowances for the screen size.

Perhaps a good idea to have two entry points into your application, one for the desktop and one for the PDA.

It would be good if Revelation had a White Paper on the topic…. hey Rev Guys?

Please let us all know how you get on.

Jeff:

The short answer is that unless you use terminal server you will need to use another technology to present the info on the device, then establish a conduit to OI.

Some Choices:

see http://www.palmos.com/dev/tools/

Web clipping applications are easy to put together and OK for simple applications. Palm developed the WQA format for wireless applications but you actually can use then without a wireless connection. The benefit is that you can generate palm apps on the fly from inside OI. The cost is that they support pretty simplistic applications.

you can download our example application here

Plan B is to get an application generator like PenDragon, Satellite Forms or AppFactory. They ease the task of generating an application, and usually want to synch with an ODBC database. You can use this in conjuction with datasets to put up an application and synchronize by replicating via a shared mdb file or the OpenInsight ODBC driver.

I prefer AppFactory because it is cheap and forces you to keep the application very simple.

Plan C is to write a J2MEE or .Net based application. The latest PDA's should all support what you develop. We have not tested JOI on J2MEE devices, but if you have a wireless connection you might be able to deploy JOI forms. The goal of Plan C is to ensure that your investment in this thin-client app can be used on whatever device your clients want to use.

Plan D is to write a true palm Application and a conduit to your OI database. With XREV.dll, the COM object that ships with OI4.13, you can write the conduit in VB, or you can keep it simple and pass text files. The benefit is full control, the cost is coding to specific OS in a low level language.

What would I do?

If you have wireless connectivity, start with the Palm web clipping application, at least do your prototype in that. If you will not have connectivity, start with Appfactory, prototype in that.

Hope this helps,

Bob

Hi Jeff

Check out http://www.ptshome.com/tracerplus.htm. It allows you to develop simple applications on the Palm and transfer data between a PC and Palm based PDA. I am developing an Arev inventory audit system to collect inventory counts using a Symbol Technologies barcode scanner that uses Palm OS. TracerPlus is great for prototyping an application and redeveloping with Code Warrior or other Palm development tools later if more functionality is required.

Cheers

Aiden
