DroidDB Tip of the Month

DroidDB® Tip for January 2017

Making an Edit Control Required

You might want to designate an edit control as "Required" (i.e. the user had to specify a value in it). This can be done using macros.

Say you wanted designate that the Description edit control of the sample Expenses form is required. First, create a macro (EDIT | MACRO/EVENTS) called CheckDescription:

  • Step 1: SKIP if @length(Description) = 0 then 1 else 0
  • Step 2: Return from macro
  • Step 3: Message box 'Please provide a Description'
  • Step 4: Stop macro

Then, change the "On Leaving Record" form event (EDIT | MACROS/EVENTS | EVENTS) to CheckDescription.

Top rated! I needed a solid database application development tool for mobile devices. I chose DroidDB for Android OS because it provided a way to get a strong product to market quickly. DroidDB is relational, gives me control over form layout, handles macros, and supports events. It works on all Android versions I have tried and is a great companion product to SYWARE’s VisualCE.
