Hi, I have and Delphi program which uses ole automation to handle AutoCAD ( CreateOleObject('AutoCAD.A pplication ') etc.). When AutoCAD is busy and command is send trough OLE a 'call was rejected by callee' OLE exception is raised. My question is. How I can restore AutoCAD back to the idle state from my program?

Let's say that I have an drawing open in AutoCAD (opened via OLE automation). Let's assume that my AutoCAD startup configs launches purge dialog by automatic. So now I have opened AutoCAD via OLE and it has purge command runing and it's busy.

Edit OLE Objects in Drawings. Edit OLE Objects When AutoCAD Is the Source Application. Double-click the OLE object to start the program. Any ideas?Why are Images or OLE Object not Printing from AutoCAD? That you have the computer knowledge to download and install a software program on your. This is typically caused by the Raster Image and OLE Settings on the AcroPlot AutoCAD Options Tab. We set the defaults to what normally works to create the.

I can't do anything from my Delphi program until that dialog is closed. I can't send ESC key code (which closes the purge dialog) to AutoCAD via OLE or I get that exception I mentioned above. What I have to do to get rid of that dialog (or anyother command which keeps AutoCAD busy) - thanx?

I mean if automation object (excel or word) is busy you can't send new command through OLE sametime. In excel and word is that good point of view that they don't 'hang-on' in a busy state. They return back to idle state when operation is done. In AutoCAD it halts to waiting user input which causes problems with ole automation.

Somehow I should have a way to send a 'message' to AutoCAD to continue and not to wait the user input (canceling the current operation or something like that). Even in Excel or Word?!? Driver Axioo M720sr Windows 7 on this page.

Hello, I have found the solution for this problem already. If anyone wants to know how to solve ole automation 'call was rejected by callee' EOleSysError exception here comes a tip. Exception is raised when automation application is busy and you try to use it through ole. In Microsoft Office and Autodesk AutoCAD there's a property which you can read from olevariant to check if automation application is busy or not (see SDK documentation of that application). If application is busy then ole cannot be used until application is idle. In AutoCAD the problem is that it doesn't come back to the idle state until user gives some input to command-line and you can't send that input through ole automation because it's busy.

You must build a 'wrapper' to get AutoCAD application window caption or handle and send those input commands to AutoCAD with SendMessage function. Problem there is that AutoCAD ClassName changes everytime when application is started and even application window caption changes depending is there drawing open or not. Or is that drawing maximized or not and so on. So FindWindow function cannot be used because caption of application and classname is unknown. But by using EnumWindows WinAPI call you can get all top level window handles and captions. So it can be used to find out which window captions starts with 'AutoCAD' text string for example.

And when you have the caption or handle you can use FindWindow and SendCommand functions to send commands directly to the AutoCAD command-line. I hope this helps someones out there.
