skip error message when open dxf failed?

Hi, would anyone let me know how to skip the error message when open dxf failed? I have an automation running in AutoCAD to open several files one by one automatically. The problem is: when a dxf file can not be opened for some reason, autoCAD says: "Invalid or incomplete DXF input -- drawing discarded. press ENTER to continue:", and I have to manually click "ENTER" to let it continue. Is there workaround for this? I tried to set ShowWarningMessages = false and that does not help. Thanks a lot.

 

Hi there,
I made a routine that inserts dxf's, it's started with a .bat file and runs in SDI. The .bat starts up acad with a script-file that calls the lisp. I modified the error handler so that it puts an entry in a log-file whenever an error occurs and then continues with the script, which starts a new template-based drawing and starts the lisp. Works fine, when a bad dxf is present the routine keeps on going (also works when opening dxf-files).
I think all you have to do is modify the error handler so the program continues.
Hopefully this will help.

 

This seems to be the right thing to do. Now, I am using VB to write an ActiveX control to start AutoCAD, and everything is in my VB program. I know in Lisp the error function can be redefined. But how can I define the error event in a VB program? Thanks.

 

OK, it seems that I can make it. DXF is different from DWG so that it should be IMPORT instead of OPEN. For DWG, the error can be caught by documents.open(filename); for DXF, the error can be caught by document.import(filename) (the document should be created by documents.new(name) first).

 

hi zhangyi,
sorry I didn't respond sooner, am not much online.
Don't know much about VB yet so I can't help you there but you seem to be getting somewhere...
I'm using ACAD 2004 (and 2004 MAP), the displayed message with an illegal dxf is the same. My error-handler is as always defined in the first part of the lisp, from this place I call a subroutine for creating a log-entry and then switch to running my script-file.
success with the error-catching, good hunting.
