    Default Opening a drawing from AutoLISP...

    Hello:

    I've got an AutoLISP routine that opens an existing drawing file from the command line. The command works, but upon completion AutoCAD returns to the current drawing, rather than the newly opened file.

    Here's a code snippet:

    Code:
    (defun C:DETLOPEN ( / )
    
    	(setq olderr *error*)
    	(setq *error* dellerr)
    	(setvar "CMDECHO" 0)
    
            ...
    
    	(setq stDetailName (strcat stDetailFolder stCSIDivision stDetailName ".dwg"))
    
    	(if (findfile stDetailName)
    		(OpenDwgFile stDetailName nil)
    		(alert "File not found...")
    	);if
    
    	(princ)
    
    );defun
    
    ;; ---------------------------------------------------------
    
    (defun OpenDwgFile (arg1 arg2 / )
    
    	(vla-Open (vla-get-Documents (vlax-get-Acad-Object)) arg1
    		(if arg2
    			:vlax-true
    			:vlax-false
    		);if
    	);vla-Open
    
    ); defun
    
    ;; ---------------------------------------------------------
    Any ideas how I can force AutoCAD to make the newly opened file the active drawing?

    Vla-activate the newly opened drawing

    Try the following as a replacement of your OpenDwgFile routine:

    Code:
    (defun OpenDwgFile (arg1 / )
      (vla-activate (vla-open (vla-get-documents (vlax-get-acad-object)) arg1))
      ); defun
    Note that I have removed arg2. As long as the routine is trying to return a value (i.e. vlax-true or vlax-false) it will continue running after the new drawing is opened, and this will serve to keep focus from shifting to the new drawing. Also, I am unsure of its purpose in any case, as it only tells OpenDwgFile to return what you want it to return.

    Note that

    Code:
    (OpenDwgFile stDetailName nil)
    Will need to be replaced by

    Code:
    (OpenDwgFile stDetailName)
    in C:DETLOPEN

    I hope this proves helpful.

    The parameters are as follows:
    Code:
    (vla-open <Document> <File String> <Read Only :vlax-true or :vlax-false> [and the optional Password parameter])

    Yes, on reflection afterward I figured it might be something like that. I'm afraid I was a bit rushed, and didn't take the time to consult the help file

    Well, now you don't even have to do that.

    I realize this is a very old thread, but I hope someone may be able to help.

    The above code has been very helpful to open drawings and set them active.

    However, using the vla-open function, you do not know if the drawing opened as read-only because another user already had the drawing open.

    My questions:
    How can you check a drawing to see if it is open by another user before you open it with your function?
    How can you check an already open drawing to see if it is read-only. In other words, errors result if you try to save a drawing that was opened as read-only. I need to check current drawing's read-only status.

    I look forward to any replies.


    Regards,
    Jerry
