Forcing an escape

I have an app that creates a form within AutoCAD. What is happening is that
some users are clicking on some buttons on the form while a command is still
active in AutoCAD (i.e Pan) and they're getting an error message. I want to
be able to have my buttons perform an 'Escape' to cancel any active AutoCAD
commands before performing the functions of the button. I've tried sending
different commands but to no avail.

This is for ACAD2K throught to ACAD2K5. I have written my app in Delphi but
that souldn't matter.

TIA

 

Yes, in addition to allowing a command null it would be nice to be able to return the current active command name and to also intercept the user activities as they occur prior to allowing the activities to pass on to the commands. The other CAD application works that way.

 

have you tried sending "^c^c"

 

Yes.

 

Try Using this: SendKeys "{ESC}" & "{ESC}"

 

Ive tried sending everything I can think of. It doesn't seem to be what is
sent as being the problem. It's a matter of the fact that ACAD will not
allow you to interupt it. I continually get a 'Call was rejected by Callee'
error. As I mentioned in my original post, I am using Delphi 7 to develop
with. Maybe this does make a difference because it seems like ACAD will not
allow a SendCommand to be passed while it is currently in the middle of
something i.e. Pan

 

I've also tried all these from within an Acad VBA. Nothing appears to happen. The commands seem to be ingnored and they are not stored to be executed after the VBA closes out.

 

Remember to set focus to AutoCAD before using SendKeys

AppActivate(ACADApp.Caption)
SendKeys.Send(Chr(27) + Chr(27))
AppActivate("YourApplication")

 

Unfortunately, SendKeys is not available with Delphi.

 

Darrell - Can you tell me if your form is running in a
standalone .EXE or in an ActiveX DLL that's running
in AutoCAD's process?

That's the first question. Solving your problem is quite
easy, but I need to know a bit more.

 

Tony, I am having the same problem
with some of my buttons on a vba v02 form
which fires code with only vba methods
...no sendcommand.

Command line needs to be cleared out similar
to hitting esc key before the code will run. I have
trapped in error check, but would rather solve
when user clicks the button and before code is
excuted.

Thanks
Paul

 

Sorry to jump in the middle btw...

I think I have isolated the error
to >.Application.Update...

If command line needs to be
cleared I get the error. Strange
part is if I go into the debug it
lets me step thru the application
update without error...

Thanks...

 

My form is running in a stand alone .EXE
