Lock Commandline

SRSDS — Fri, 31 Jul 2020 18:32:58 GMT

I think I'm having a problem with some people being too fast for my app to keep up with.

If they are slow it doesn't seem to be a problem but if they are hammering in commands AutoCAD crashes.

Does the comandline wait for instructions to be complete before starting the next?

Or is there a way to disable the commandline until a routine is finished?

Does doclock do this?

Are you talking about a LISP program? There is a delay/pause command that slows the program down to allow for user input.

It's a Visual Studio app.

I do have a pallette that's a likely cause of the problem but I have spent a lot of time trying to making sure I cancel out of any active command before starting a new one.

I was wondering if the operations from the commandline are stalled (or stacked?) until the previous command has finished.

A script file seems to wait for the previous operation to complete so I assume it does.

Hi,

If the issue is related to the palette (i.e. a modeless UI), a simple and safe way should be callign custom command methods from the palette as recommended by Kean Walmsley's in this topic.:

"Once again there’s our important rule of thumb when it comes to implementing a modeless UI: rather than manually locking the current document, it’s safer to define a command – which will implicitly lock the current document – and call that from the UI via SendStringToExecute()."

Doing so, you let AutoCAD manage the commands stack.

You can find and example in this tutorial (palette section).
