Can't compile the Qutlook example

**Matt84** · 30th August 2007, 09:33

Hello,

I use the Qt 4.3.1 commercial edition for Windows, and I want to test the ActiveQt example : "Qutlook".

Unfortunately, during the compilation of this example, I get the following errors :

Qt Code:

Does anyone have the same problem as me when compiling this example?

Thanks for your help.

PS : Office Outlook 2003 is installed on my computer.

I suggest you report that to Trolltech using the task-tracker.

I have the same problem, 3 years after.
But I don't see any similar problems on the net.
Then I am in doubt with the usage of this functionality.

I have found a solution !

"Enums cannot be forward declared. First of all the C++ standard does not define forward declaration. It defines incomplete types." (from http://bytes.com/topic/c/answers/622...claration-enum)

So, gcc/mingw is right, and doesn't compile this source.
It is a bug, perhaps in the msoutl.olb file, perhaps in the dumpcpp tool (I don't know why, but I think it is from the olb file)

If you don't intend to use this enum, you can easily define it BEFORE the inclusion of the msoutl.h file, like this:

Qt Code:

Switch view

namespace Office {  enum MsoFeatureInstall { value };  }
 
//! [0]
#include "addressview.h"
#include "msoutl.h"
#include <QtGui>
....

namespace Office {  enum MsoFeatureInstall { value };  }

//! [0]
#include "addressview.h"
#include "msoutl.h"
#include <QtGui>
....

To copy to clipboard, switch view to plain text mode

Yours, J..

I don't know why it worked; it didn't recompile the msoutl.cpp, but it is not correct and doesn't work.
I think it is a bug in the dumpcpp tool, and opened a bug in their bug tracking tool: http://bugreports.qt.nokia.com/browse/QTBUG-11721

So, no resolution, for yet.

Hi guys. You are quite correct. Enums can not be passed from COM server. All data is via class declarations. The problem is caused by -gccdump incorrectly creating msoutl.h, but the answer is simple.
Open msoutl.h in editor and change line - "enum MsoFeatureInstall;" - to "class MsoFeatureInstall;"

#include <qdatetime.h>
#include <qpixmap.h>

struct IDispatch;

// Referenced namespace
namespace Office {
class Assistant;
class COMAddIns;
class LanguageSettings;
class AnswerWizard;
class MsoFeatureInstall; *** changed from - enum MsoFeatureInstall;
class CommandBars;
}

.............................

**ricdata** · 26th January 2011, 11:43

Sorry guys

First assumptions not quite right. Enum is required and needs to be declared prior to forward declaration. Try this. It does compile now.

// Referenced namespace
namespace Office {

enum MsoFeatureInstall {
msoFeatureInstallNone = 0,
msoFeatureInstallOnDemand = 1,
msoFeatureinstallOnDemandWithUI = 2
};

// forward declarations
class Assistant;
class COMAddIns;
class LanguageSettings;
class AnswerWizard;
enum MsoFeatureInstall;
class CommandBars;
}
