application is busy in customized version of Script Pro 2

[wesbird]

Hi,
I'm modified Script Pro 2 from autodesk lab. Now I have this problem, sometimes, I got this error message

"The message filter indicated that the application is busy. (Exception from HRESULT: 0x8001010A (RPC_E_SERVERCALL_RETRYLATER))"
at

object ret = ActiveDocument.GetType().InvokeMember(
"SendCommand",
BindingFlags.InvokeMethod,
null, ActiveDocument, OnedataArray
);

 or

short fd = (short)ActiveDocument.GetVariable("FILEDIA");

 ActiveDocument come from 

ActiveDocument =
AcadDocuments.GetType().InvokeMember(
"Open",
BindingFlags.InvokeMethod,
null, AcadDocuments, ThreeVariable
);

I understand those are out-process call. Maybe AutoCAD is still doing something when it happens. right now I increase the wait time right before the call like:

Thread.Sleep(100) -> Thread.Sleep(500)

what should I do to avoid this problem.

Thanks

Wes

Hi,

I suggest you to use IsAcadQuiescent() before sending the command to AutoCAD. IsAcadQuiescent is implemented in ScriptPro specifically to check for AutoCAD state.
