I am working on an application that uses map to query data, then saves the data to a file, and repeat. It works flawlessly when I use a commandmethod with commandflags.session, But, when I try to run the same code from a form button, I get "drawing is busy". The command from the form button ignores the commandmethod and the commandflags. I am guessing that "sendstringtoexecute" would work, but I would prefer to not do it that way.
What am I missing? Is there another way to lock the session?
Here is what I am trying to do.
drawing1 is open and the user presses the button
data is queried and saved as 1.dwg
close and discard drawing1
open a new doc drawing2
data is queried and saved as 2.dwg
close and discard drawing2
open a new doc drawing3
Solved! Go to Solution.
That's even better - thank you. Starting at an empty drawing1, the user presses the button, and the queries start in drawing2. When it's finished, the user is back at an empty drawing1.
Good idea - sorry. It took a bit of digging and I was in a rush. Thanks again Alexander and tony t (again and again...).
