ArcPad Tips and Thoughts

If anyone is developing for ArcPad 8.0, make sure you get service pack 1. This will correct a whole host of issues with the AXF files. Also, if you wish to connect to an AXF, here is an example:

dim objRSPS, pDS
Set objRSPS = Application.CreateAppObject("RecordSet")
Set pDS = Application.CreateAppObject("DataSource")
set objRSPS = pDS.OpenLayer("")
If objRSPS.RecordCount > 0 Then
End If
...do other stuff...

So basically what is happening here, the objRSPS is creating a recordset object, then pDS is a data source object. pDS opens the data source via path name. objRSPS obtains the data set's records by referencing what layer you want from the axf database (axf is a compact sql server).

Note: the axf is picky, and it will tell you. If any domain values are invalid, it will catch it. So keep your databases clean if you are going to use this stuff.

Note 2: the shapefile is going away in arcpad, so get use to the AXF way of doing things.
