AcadDocument.SendCommand

[Anonymous]

Good afternoon, I'm writing an application with C#2008 that need to send -ETransmit command via SendCommand API using AcadDocument.
This is what I do:

string progID = "AutoCAD.Application.18";
Type acType = Type.GetTypeFromProgID(progID);
acApp = (AcadApplication)Activator.CreateInstance(acType, true);

acApp.ActiveDocument.SendCommand("-estransmit\r");
acApp.ActiveDocument.SendCommand("C");
acApp.ActiveDocument.SendCommand("MyZIPFilePath\r");

acApp.ActiveDocument.SendCommand("C");
acApp.ActiveDocument.SendCommand("MyZIPFilePath\r");

Everything works fine when the firt SendCommand is executed, but when it try to execute the others an exception is raised HRESULT: 0x80010001 (RPC_E_CALL_REJECTED). I tried to add a WaitTime beetween each SendCommand, but I got the exception as well. I know this issue is due to a "time" propblem, but I can't figure out how to solve it. Any ideas?

Thanks in advance

Have you tried sending everything in a single call to SendCommand() ?

SendCommand("-ETRANSMIT\nC\nMyZIPFilePath\n");

You can separate the response to each input prompt with a newline ("\n").

Yes I did, but it doesn't work as expected every time. Sometimes the command works fine and AutoCAD generate MyZIPFilePath file, but other times I found AutoCAD waiting for a command, sometimes waiting for "C" parameter, sometimes waiting for the path.

I think this is due to a time issue because it seems that C# is faster than AutoCAD, so I splitted ETransmit in three different commands. "Googling" around the net, I found a tip inside Microsoft Site (MSDN) that explain the problem and suggest a possibile solution using a static class that implement IOleMessageFilter interface.

Link:

Using this class I solve the problem but when the application send the second command nothing happen. Both application (AutoCAD + C# application) are still working but AutoCAD didn't receive the command and C# application didn't get any exception.
I need to send ETransmit via SendCommand because I must automate this operation in order to decrease our drawing time. Maybe you know a "shortcut" to do ETransmit in way I don't know, but in the future I'm sure I will need to use SendCommand maybe with "multiple" send commands, so I want to resolve the problem using this way...

Thanks again

I would try to combine the message like Tony suggested:

SendCommand("-ETRANSMIT\nC\nMyZIPFilePath\n");

If you do not combine the message, the first SendCommand starts the "-etransmit" command and is waiting for additional input. While waiting, you cannot use the SendCommand function again (it will be rejected).

Just an idea, the second step of the "-etransmit" command brings up a dialog box. Maybe that is the source of your problem. Try changing the FILEDIA system variable to 0 before running the combined command "-ETRANSMIT\nC\nMyZIPFilePath\n".

Yes!!!! Your suggestion solved my problem. Setting FILEDIA == 0 when I send the full command everything work EVER as expected.
Thank you very much for your precious help.
