Can't add a picture to a powerpoint slide. COM object method returns error code: 0x80020005;

[jeffe...@gmail.com]

Hello,

I modified the sample file, PowerPointAutomationSample.java, which included in the comfyj-2.9-windows-32_64-bit.zip for adding a picture to a powerpoint slide.

But I don't understand why I always got this error "Exception in thread "AWT-EventQueue-0" com.jniwrapper.win32.com.ComException: COM object method returns error code: 0x80020005; DISP_E_TYPEMISMATCH".

 

Please refer to the following source code. There are 3 different functions for adding a picture to a powerpoint slide. But I got errors no matter which one I use.

Please kindly tell me if there's anything wrong or something I missed.

 

 

Thank you.

Jeff

Hello,

I forgot to say...that I tried adding a picture to a powerpoint 2003 slide and a powerpoint 2007 slide. And I got the same error.

 

Your earlier reply will be very appriciated.

Thank you.

Jeff

Hi Jeff,

In order to fix this issue you just need to inform 'shapesAutomation' object that it has to work with a DispInterface object (_shapes in your case), so it should use an appropriate order of function call parameters.

The code snippet below demonstrates the solution:

        Automation shapesAutomation = new Automation(_shapes);

        shapesAutomation.setDispInterface(true);
        try {

            shapesAutomation.invoke("addPicture", new Object[]{

                    new BStr("d:\\screenshot1.png"),
                    new MsoTriState(MsoTriState.msoFalse),
                    new MsoTriState(MsoTriState.msoTrue),
                    new SingleFloat(0),
                    new SingleFloat(0),
                    new SingleFloat(300),
                    new SingleFloat(500)});
        } catch (AutomationException e) {
            e.printStackTrace();
            ExcepInfo exceptionInformation = e.getExceptionInformation();
            String bstrDescription = exceptionInformation.getBstrDescription();
            System.err.println("bstrDescription = " + bstrDescription);
        }
        shapesAutomation.release();

You may also notice that I also added handling of AutomationException which should intercept such DISP_E_TYPEMISMATCH COM exceptions and provide the ability to get the extended exception information (ExcepInfo) when such error occurs.

All automation objects (shapesAutomation) should also be released using the .release() method to handle the references to COM object properly.

Please let me know if you have any further questions.

Sincerely,
Serge

Hi Sergei,

Here I have two more questions

1) Is it possible to monitor what users did in the PowerPoint such as selet a shape, change a shape's size, change a shape's

position,......etc. via comfyj ?

2) I tried the PowerPointEventsHandling sample also, it works. But I don't know why there are error messages also. Those error

messages are listed below:

[Main message loop] ERROR com.jniwrapper.win32.e -

Hi

1) ComfyJ library is COM bridge. So, it can be used for monitoring those actions only if a COM library itself provides the corresponding API for handling those actions.

2) Those messages are actually debug output messages, and we already changed the logging level for them in new version of ComfyJ. So, taking into account that PowerPointEventsHandling example works for you even if it throws those errors, you can omit those messages.

Sincerely,
Serge
