ddeTopic Setting Ignored in 5.2.10
Posted: Tuesday, July 11, 2006 4:06 PM (EST)

In version 5.2.10, setting ddeTopic for an Edit object does not seem to work:

{rho} 'fmPM.ed' {Quad}WI 'ddeTopic' 'PROGMAN|PROGMAN'
0 0
      'fmPM.ed' {Quad}WI 'state'
class                Edit
name                   ed
where 14.375 34.5 1.5 10
      'fmPM.ed' {Quad}WI 'ddeMode' 'cold'
{Quad}WI DDE ERROR: Need application¦topic in ddeTopic
      'fmPM.ed' QuadWI 'ddeMode' 'cold'
                ^

It's highly likely that your problem is due to DDE connectivity being disabled by default in version 5.2. The following paragraph from page 13 of the 5.2 Update Manual (52update.doc) should address your problem:

The default setting for [Config]EnableDDE is now zero. If you still use the long-deprecated Dynamic Data Exchange in your application, you must reset this value in the .INI file to 1. Having DDE enabled causes multiple copies of APL running as ActiveX servers to wait until all of them are closed before exiting. It may also have other consequences.

Yes, this did it.

Shouldn't the V6 manual's section on DDE mention this?

Thanks,

Dave

Yes. It will be included in a future version of the (Windows Reference) manual.
