VB.Net 2005 & Windows Mobile

[antonio622]

I posted a recent question on this topic some time ago about the basics referring to mobile device types and general info. Thanks to all information recieved I purchased VS2005 Professional and A Verizon Pocket PC Phone.

I had to install Compact Framework 2.0 onto the Windows Mobile 5 OS

I have tested VB.Net 2005 and the Pocket PC with basic text input programs. Works Great!

My new questions are kind of basic as well:

Can a Pocket PC running Windows Mobile 5 read and write to and from a database in its own ROM or Memory Card without having to be connected over a network to the database?

For my project for a Heating & Air Conditioning Co. I want each service technician to have his own PocketPC and when called out on a service to record customer information and various calculations required (Being disconnected from a server database - database only residing on the Mobile ROM or Memory Card)

Then when reporting to work the next day each Service Tech is to connect his Pocket PC to the main desktop computer with a main program which can read each of the Service Techs Pocket PC's with the same Database Structure and of course different records. When the main program reads each Pocket PC it will then copy each one to the main Database and then delete them on the PocketPC to save Memory for the next Service Day.

Is this a practical idea or does everyone recommend using a connected Database?

I am writing the program with my idea above to save on cell phone bills and also to be able to record this info at all times even when a connection cant be reached. I live in an area with very poor cell phone reception.

Thanks

That seems the best way to go. I would suggest going with sqllite for this. or xml depending on the amount of data. On the mobile device. And when connected you just transfer the data to the real database.
