Visual Basic v6 and DDE problem

[isocam]

Can anybody help?

I have the following Visual Basic 6 code that I am using
to control AutoCAD LT from.

sExePath = "C:\Program Files\AutoCAD LT 2004\aclt.exe"
sAcadVersion = "AutoCAD LT"
Text1.LinkMode = 0
Text1.LinkTopic = "AutoCAD LT.DDE|system"
Text1.LinkMode = 2
Text1.LinkExecute OutputString & Chr(13)

My client wants to use a similar routine for both
AutoCAD 2002 and AutoCAD 2006, thus:-

sExePath = "C:\Program Files\AutoCAD 2006\acad.exe"
sAcadVersion = "AutoCAD"
Text1.LinkMode = 0
Text1.LinkTopic = "AutoCAD.DDE|system"
Text1.LinkMode = 2
Text1.LinkExecute OutputString & Chr(13)

Obviously...

I know that the paths change etc, but it still will not
work. Any assistance would be very grateful.

Many thanks in advance!

Yow, it's been ages since I've used DDE to communicate with ACAD, but if I recall correctly the LinkTopic must match the version you're using. For 2006 try:

Text1.LinkTopic = "AutoCAD.R16.DDE|System"

Or it might even have to be:

Text1.LinkTopic = "AutoCAD.R16.2.DDE|System"

For 2002, try:

Text1.LinkTopic = "AutoCAD.R15.DDE|System"


If at all possible, you might want to update your code to get a reference to ACAD and use the object model's methods & properties, rather than continuing to depend on DDE.

this is not possible since LT does not expose an API.

Note that the original poster was asking about moving the code to AutoCAD 2002 and 2006, not LT.

Wrong.

Oops, sorry. Just read the middle part of the OP. Yikes. I hate that.

Heh-heh, no problem, I've made the same mistake myself in the past. 🙂

That's why I didn't start off my reply to Bob with something like "y dont u learn 2 reid u #@$%...!!!!! " even though that attitude seems to be getting more and more popular in some forums these days. I know I'm not infallible, not even close, so I don't expect other folks to be perfect either. Geez, sounds like it's time for a group hug! 😉
