I generated a wrapping for MS Excel 03.

In that, there is an _Chart class.  It has the following 3 methods. (the corresponding impl class has the same ones, they all call the came virtual method - 63).

    /**
     *
     */
    void copyPicture(
        XlPictureAppearance /*[in]*/ Appearance,
        XlCopyPictureFormat /*[in]*/ Format,
        XlPictureAppearance /*[in]*/ Size,
        Int32 /*[in]*/ lcid)
        throws ComException;

    /**
     *
     */
    void copyPicture(
        Variant[] /*[in]*/ optParams0,
        Int32 /*[in]*/ lcid)
        throws ComException;

    /**
     *
     */
    void copyPicture(
        Int32 /*[in]*/ lcid)
        throws ComException;

The MSDN docs are here: http://msdn.microsoft.com/en-us/library/aa223846%28office.11%29.aspx

The interesting part is the last param required in all of the above calls isn't included in the MSDN docs.

When I try to execute:

_chart.copyPicture(new Int32(0));

I get:

Caused by: com.jniwrapper.FunctionExecutionException: Parameter types or their count are not correct
        at com.jniwrapper.Function.invokeVirtualFunc(Native Method)
        at com.jniwrapper.FunctionCall.a(SourceFile:131)
        at com.jniwrapper.FunctionCall.callVirtual(SourceFile:58)
        at com.jniwrapper.win32.com.impl.IUnknownImpl.invokeVirtualMethod(SourceFile:661)

        at generated.excel8.excel.impl._ChartImpl.copyPicture(_ChartImpl.java:1270)

Now there are competing types here, _Chart and ChartObject.  What is the difference between the two?  I noticed in the implementations that the _Chart object uses invokeStandardVirtualMethod and the ChartObject uses Automation.invokeDispatch.  Should I be sticking to the one over the other?  What is the major difference?

ChartObject has the same 3 methods, but they have the following signatures

_Chart

public static final String INTERFACE_IDENTIFIER = "{000208D6-0000-0000-C000-000000000046}";

ChartObject

public static final String INTERFACE_IDENTIFIER = "{000208CF-0000-0000-C000-000000000046}";

    /**
     *
     */
    Variant copyPicture(
        XlPictureAppearance /*[in]*/ Appearance,
        XlCopyPictureFormat /*[in]*/ Format);

    /**
     *
     */
    Variant copyPicture(
        Variant[] /*[in]*/ optParams0);

    /**
     *
     */
    Variant copyPicture();

I also found the following for your other package.  http://support.teamdev.com/message/9433#9433  Should I just use export instead?

Any help would be appreciated.

Thanks,

Adam.
