Notice that Listbox Test.vi works, but Listbox Test.exe does not. To prove that this is a problem with the Run-Time engine, change "Listbox Test.exe" to "Listbox Test.llb" and open "Listbox Test.llb\Listbox Test.vi" in the Development Environement -- the proplem goes away.

CAR#: 3RK9A23A.

Status: Fixed in 8.0.1

:headbang: Doh! It looks like the problem affects Multicolumn Listboxes and Tree Controls, too. The whole Drag and Drop, feature might be hosed in EXE's.
Hosed is the right word. Welcome to X.X.0 releases.... Oh well, I've had a glitch or two in some of my x.x.o releases :blink:

The good news will hopefully be that it is a single point failure with an easy single point fix, either in 8.0.1 or a quick patch from one of the NI elves. I really need D&D to work in EXEs for a project I'm estimating/scoping now. That means I have a little time, otherwise I'm looking for an ActiveX control and I really don't want to do that.

Here is the response from NI Support

Thank you for contacting National Instruments. The behavior in executables

involving Listboxes has already been reported to R&D as a CAR (Creative

Action Request), and we are currently working on fixing it in future

versions of LabVIEW. Thank you for your attention to this issue.

I will also look into the record regarding Multicolumn Listboxes and Tree

Controls to make sure that we have covered all the issues that need to be

fixed in future versions. If you have any further questions, or if you come

across any additional information, please let us know so that we can

continue to improve LabVIEW.

What is up with this rash of newspeak of late? "Creative Action Request". Just call a bug a bug.

Here's some more:

Consent to an unconstitutional reduction in civil liberties == "Patriotic"

Opposed to government policy == "Unamerican"

Kidnap and torture == "Rendition"

Back in my days at NI, CAR stood actually for "Corrective Action Request" and probably still does. The guy who wrote that answer probably just was tinkering about the creativeness he could do in writing a LabVIEW program instead of answering a technical support. Working in technical support can have this effect on you! :laugh:
