How to Set and Get Custom Properties to a word document

[venkky venkky]

Hi,

I would like to add custom properties and read them to a MS Word
Document using ComfyJ generated APIs instead of manually opening File
--> Properties --> Custom and add properties.

Please kindly help me on this.

Regards,
Venkky

Hi,

In Word API there is the ability to manage custom document properties. You
can access them via _Document.getBuiltinDocumentProperties() method:
http://msdn.microsoft.com/en-us/library/microsoft.office.interop.word._docum
ent.builtindocumentproperties.aspx

or _Document.getCustomDocumentProperties() method:
http://msdn.microsoft.com/en-us/library/microsoft.office.interop.word._docum
ent.customdocumentproperties.aspx

Sincerely,
Serge

Hi,
Thanks for the reply.

I have written the following code to get the count of custom
properties,

OleFunctions.oleInitialize();

IUnknown activeWordApp =
ComFunctions.getActiveObject(Application.CLASS_ID);
_Application application =
Application.queryInterface(activeWordApp);

_Document doc = application.getActiveDocument();
IDispatch iprops = doc.getCustomDocumentProperties();
CustomPropertiesImpl cProps = new
CustomPropertiesImpl(iprops);
Int32 count = cProps.getCount();

OleFunctions.oleUninitialize();

I am getting the following exception when i am trying to execute this,

Exception c0000005, at 771311E0

Please kindly help me to resolve this.

I am testing this on, MS Office 2003 installed on Win XP Service Pack
3, 32 bit.

Thanks & Regards,

Hi Venkky,

According to this support article:
http://support.microsoft.com/kb/303296/en-us "DocumentProperties and the
DocumentProperty interfaces are late bound interfaces. To use these
interfaces, you must treat them like you would an IDispatch interface."

This probably explains why you were not able to invoke methods of that
object via appropriate interface, which in fact is early binding technique.

So, in this case I suppose you can use Automation to access fields and
method of that object, like it's demonstrated in the example below:

IDispatch properties = workbook.getBuiltinDocumentProperties();
// IDispatch properties = workbook.getCustomDocumentProperties();

boolean useCurrentThread = true;
Automation propertiesAutomation = new Automation(properties,
useCurrentThread);

Variant propertyCount = propertiesAutomation.getProperty("Count");
int count = (int) propertyCount.getLVal().getValue();
System.out.println("count = " + count);
for (int i = 1; i <= count; i++) {
Variant item = propertiesAutomation.getProperty("item", i);
Automation itemAutomation = new
Automation(item.getPdispVal(), useCurrentThread);
try {
Variant itemName =
itemAutomation.getProperty("Name");
System.out.println("itemName = " +
itemName.getValue());
Variant itemValue =
itemAutomation.getProperty("Value");
System.out.println("itemValue = " +
itemValue.getValue());
} catch (AutomationException e) {
ExcepInfo information = e.getExceptionInformation();
System.err.println("description: " +
information.getBstrDescription());
}
itemAutomation.release();
}
propertiesAutomation.release();

I also would like to notice that it's not necessary to use
OleFunctions.oleUninitialize(); at all, because it may interfere with
automatic memory management in ComfyJ.

Please let me know if you have another questions.

Sincerely,
Serge
