I writing an interface in Visual Basic that uses the Acrobat 5.0 SDK.
I want to change the default color of the highlighter. To highlight a
passage in yellow, the code is just:     
r = AcroExchApp.SetActiveTool("Highlight", True)
I would think there is an easy way (one line or two) to change the
highlighter color to red (in the application itself you can right
click to change the color, but I need to do it in the program).
However, nothing I have tried works in Visual Basic, and so the
applicatin crashes and the pdf file locks.  I just want an example
that will work using Visual Basic. It can be calls to the Acrobat SDK
or Javascript code that will work in VB to change the default color to
red. Thank you!
