Hi all,
I would like to set the DisplayAlerts property on an Excel ActiveX
object embedded in an application I have. However, when I try to set the
property it remains unchanged. I am using Windows XP with Excel 2003.
Here is a snippet that illustrates the problem.
import org.eclipse.swt.SWT;
import org.eclipse.swt.SWTError;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.ole.win32.OLE;
import org.eclipse.swt.ole.win32.OleAutomation;
import org.eclipse.swt.ole.win32.OleControlSite;
import org.eclipse.swt.ole.win32.OleFrame;
import org.eclipse.swt.ole.win32.Variant;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
public class DisplayAlertsSnippet {
public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new FillLayout());
OleControlSite controlSite;
try {
OleFrame frame = new OleFrame(shell, SWT.NONE);
controlSite = new OleControlSite(frame, SWT.NONE, "Excel.Sheet");
controlSite.doVerb(OLE.OLEIVERB_INPLACEACTIVATE);
} catch (SWTError e) {
System.out.println("Unable to open activeX control");
display.dispose();
return;
}
shell.open();
OleAutomation excelSheet = new OleAutomation(controlSite);
int[] dispIDs = excelSheet.getIDsOfNames(new String[] { "Application" });
Variant pVarResult = excelSheet.getProperty(dispIDs[0]);
OleAutomation application = pVarResult.getAutomation();
displayAlerts(application, false);
pVarResult.dispose();
excelSheet.dispose();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
application.dispose();
display.dispose();
}
private static void displayAlerts(OleAutomation application, boolean
display) {
int[] dispIds = application.getIDsOfNames(new String[]{"DisplayAlerts"});
System.out.println("DisplayAlerts dispId " + dispIds[0]);
Variant result = application.getProperty(dispIds[0]);
System.out.println("DisplayAlerts before setting property = " + result);
result.dispose();
Variant variant = new Variant(display);
application.setProperty(dispIds[0], variant);
variant.dispose();
result = application.getProperty(dispIds[0]);
System.out.println("DisplayAlerts after setting property = " + result);
result.dispose();
}
}
The output from the snippet is as follows.
DisplayAlerts dispId 343
DisplayAlerts before setting property = VT_BOOL{true}
DisplayAlerts after setting property = VT_BOOL{true}
Is there anyone out there that has successfully managed to do this?
Cheers,
Paul

Hi Paul,
I see the same behaviour, but unfortunately don't know why this is
happening. However a google search of "excel cannot set DisplayAlerts"
finds several other posts with a similar problem in non-swt contexts, so I
don't think it's an swt problem. Hopefully one of them has a follow-up that
can help with your case.

Hi Grant,
Thanks for the suggestion. I think I found out what the problem is. This
is one of the application properties you cannot set until you have made
the application 'visible'. The follow snippet will let you set the
display alerts property, but at the rather ugly cost of flashing the
Excel application window.
public class DisplayAlertsSnippet {
public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new FillLayout());
OleControlSite controlSite;
try {
OleFrame frame = new OleFrame(shell, SWT.NONE);
controlSite = new OleControlSite(frame, SWT.NONE, "Excel.Sheet");
controlSite.doVerb(OLE.OLEIVERB_INPLACEACTIVATE);
} catch (SWTError e) {
System.out.println("Unable to open activeX control");
display.dispose();
return;
}
shell.open();
OleAutomation excelSheet = new OleAutomation(controlSite);
int[] dispIDs = excelSheet.getIDsOfNames(new String[] { "Application" });
Variant pVarResult = excelSheet.getProperty(dispIDs[0]);
OleAutomation application = pVarResult.getAutomation();
setVisible(application, true);
displayAlerts(application, false);
setVisible(application, false);
pVarResult.dispose();
excelSheet.dispose();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
application.dispose();
display.dispose();
}
private static void setVisible(OleAutomation application, boolean
visible) {
int[] dispIds = application.getIDsOfNames(new String[]{"Visible"});
System.out.println("Visible dispId " + dispIds[0]);
application.setProperty(dispIds[0], new Variant(visible));
}
private static void displayAlerts(OleAutomation application, boolean
display) {
int[] dispIds = application.getIDsOfNames(new String[]{"DisplayAlerts"});
System.out.println("DisplayAlerts dispId " + dispIds[0]);
Variant result = application.getProperty(dispIds[0]);
System.out.println("DisplayAlerts before setting property = " + result);
result.dispose();
Variant variant = new Variant(display);
application.setProperty(dispIds[0], variant);
variant.dispose();
result = application.getProperty(dispIds[0]);
System.out.println("DisplayAlerts after setting property = " + result);
result.dispose();
// Set it back to true, otherwise the Excel process that never dies
will have the property set to false.
application.setProperty(dispIds[0], new Variant(true));
}
}
