Steps
-------
we are trying to write the some xml content to clipborad using the myeclipse swt plug-in for that we have wtitten a class which extends byarraytransfer.java which part of swt jar, here we are using javatonative api to send the content to clipboard and we are getting the exceptio here.


we have observed that the com.globalalloc in 64 bit swt plugin is returning long where as in 32 bit its int, so we want to support our code for both of them, what is the best way of handling this[/i]

could you please let us know the reason

thanks in advance

Hi,

Sorry for distrubing but as you use SWT OLE , you may know the naswer of my problem.

I am processing the rows of a table in a word document. Sometimes it works fine, sometimes the whole application crashes.

here is the method I use


/**
	 * Returns the row in the table with the given index
	 * @param tableVar - table variant
	 * @param rowIndex - row index
	 * @return rowVariant - row Variant
	 * @throws OleException
	 */
	public static Variant getRow(Variant tableVar, int rowIndex) throws OleException {
		OleAutomation tableAuto = tableAuto = tableVar.getAutomation();
		OleUtils.printAutomation(tableAuto);
		Variant rowsVar = null;
		while (rowsVar == null){
			rowsVar = tableAuto.getProperty(101/*Rows*/);
		}
		OleAutomation rowsAuto = rowsVar.getAutomation();
		Variant rowVar = rowsAuto.invoke(0/*Item*/, new Variant[]{new Variant(rowIndex)});
		return rowVar;
	}



Any ideas what may be the reason for a crash of the application?
