Runtime.Exception on a SendStringToExecute in C# in Autocad 2009

[wperaud]

Hi,

I'm facing a problem when I want to Send a String to execute.
I want to modify XRefs when a file opens.
For each of a list of XRef to modify, I send a command thanks to the following method :
Autodesk.AutoCAD.ApplicationServices.Document.SendStringToExecute(String command, Boolean activate, Boolean wrapUpInactiveDoc, Boolean echoCommand)

Here is the command I send :
-XREF Path xrefName\n PathToTheFile\n

Most of the time, the command is successful, but sometimes, a error occurs :
Autodesk.AutoCAD.Runtime.Exception: eNoDocument
at Autodesk.AutoCAD.Runtime.Interop.ThrowExceptionForErrorStatus(Int32 errorStatus)
at Autodesk.AutoCAD.ApplicationServices.Document.SendStringToExecute(String command, Boolean activate, Boolean wrapUpInactiveDoc, Boolean echoCommand)

My command works, when I run when I paste it in autocad.
I don't understand where this error comes from. Could someone help me please ?

Thank you in advance,
Wilhelm

The way you're going about it is not reliable.

Define your own command using the CommandMethod
attribute. In your command method you can execute
AutoCAD commands synchronously using this code:

http://www.caddzone.com/CommandLine.cs

There is also a VB.NET version:

Then, when the document opens, use SendStringToExecute()
to run your CommandMethod, and have the code in it do the
work with the -XREF command.

Hi,

If I remenber well, CommandLine was a wrapper written by Tony "DiningPhilosopher" Tanzillo to P/Invoke the acedCmd() unmanaged method to be able to call AutoCAd commands synchronously.

This is obsolète since AutoCAD 2015 which brings the managed Editor.Command() method. For prior version, you shoud rather use another wrapper, also written by Tony, see this topic.
