Hi,
I want to create an Excel OLE object, and write some values into this object (in a definite worksheet). How can I do this? I have found on a Japanese side the following example:

public class OleExcel extends OleClientSite {


	public static final String ID = "ExcelSheet";
	private static final int CELL_VALUE_ID = 0x00000006;
	private static final int CELL_ID = 0x000000c5;
	private static final int SHEET_ID = 0x000001e5;
	private OleAutomation cell;


	public OleExcel(Composite parent, int style, File file	) {
		super(parent, style, file);

		OleAutomation workbook = new OleAutomation(this);
		OleAutomation worksheet = workbook.getProperty(SHEET_ID,
				new Variant[] { new Variant(1) }).getAutomation();

	
			cell = worksheet.getProperty(CELL_ID,new Variant[] { new Variant("A1") }).getAutomation();
			cell.setProperty(CELL_VALUE_ID, new Variant("Testeintrag"));
	}

}


But where do the ID's? I would prefer to solve the whole thing, like"... GetIDsOfNames (new String [] (" xxx ")".
Someone an idea? How I write in certain sheets?

I have begun linke this:

	
...
@Override
	public void createPartControl(Composite parent) {

		try {

			try {
				OleFrame frame = new OleFrame(parent, SWT.NONE);
				site = new OleClientSite(frame, SWT.NONE, "Excel.Sheet");
			
			
				//get an Excel workbook       
			     OleAutomation workbook = new OleAutomation(site); 

			     // activeSheet
			     int [] ids = workbook.getIDsOfNames(new String[]{"ActiveSheet"});


			
			} catch (SWTError e) {
				System.out.println("Unable to open activeX control");
				return;
			}

	
			
		} catch (SWTError e) {
			System.out.println("Unable to open activeX control");
			return;
		}
	}



I'm really desperate. I canĀ“t find any reasonable docu Sad

greetings, mo

Hi,

I think you're looking for a reference like
http://msdn.microsoft.com/en-us/library/aa272268(office.11).aspx . As an
added bonus, here's a utility class that I've found to be quite helpful in
the past. You can pass it any OleAutomation and it will write to stdout all
of its properties and methods with ids and descriptions (if available).

public class OLEDisplayAPI {

public static void printAPI(OleAutomation auto) { // <---
TYPEATTR typeattr = auto.getTypeInfoAttributes();
printMethods(auto, typeattr);
printProperties(auto, typeattr);
}
private static void printProperties(OleAutomation auto, TYPEATTR typeattr) {
if (typeattr != null) {
if (typeattr.cVars > 0) System.out.println("\n\nVariables :");
for (int i = 0; i < typeattr.cVars; i++) {
OlePropertyDescription data = auto.getPropertyDescription(i);
System.out.println("PROPERTY (id = " + data.id + ") :");
System.out.println("\tName : " + data.name);
System.out.println("\tType : " + getTypeName(data.type) + "\n");
}
}
}
private static void printMethods(OleAutomation auto, TYPEATTR typeattr) {
if (typeattr.cFuncs > 0) System.out.println("Methods:");
for (int i = 0; i < typeattr.cFuncs; i++) {
OleFunctionDescription data = auto.getFunctionDescription(i);
String argList = "";
int firstOptionalArgIndex = data.args.length -
data.optionalArgCount;
for (int j = 0; j < data.args.length; j++) {
argList += "[";
if (j >= firstOptionalArgIndex) argList += "optional, ";
argList += (getDirection(data.args[j].flags) + "] "
+ getTypeName(data.args[j].type) + " " + data.args[j].name);
if (j < (data.args.length - 1)) argList += ", ";
}
System.out.println(getInvokeKind(data.invokeKind) + " (id = " +
data.id + ") : ");
System.out.println("\tSignature : " + getTypeName(data.returnType) +
" " + data.name + "(" + argList + ")");
System.out.println("\tDescription : " + data.documentation);
System.out.println("\tHelp File : " + data.helpFile + "\n");
}
}
private static String getTypeName(int type) {
switch (type) {
case OLE.VT_BOOL: return "boolean";
case OLE.VT_R4: return "float";
case OLE.VT_R8: return "double";
case OLE.VT_I4: return "int";

return "unknown " + type;
