When I set the MicrosoftOutlook PageType in the main properties for the add-in - the first time it loads, an error is fired by AddIn which I can not capture. All subsequent loading of the property window works fine. It is the page that appears under the Tools > Options
Below is the exact message.
CommonPage error: the add-in has fired an exception. Object reference not set to an instance of an object.

Assembly Build Date: 2/15/2005 1:06:46 AM

Hi Dave.
Did you add any code to the property page constructor? Do you get the issue on the development PC?

I have tried on 4 machines - all the same error (it occurs only on the first loading the property window and appears 3 times in a row - 3 dialog boxes then opens the property window fine). I did not test this prior to other issues previously. It appears only on what I call the common page - Property Page located under Tools > Options and appears when I select options prior to moving to "my" tab. It does not happen on any of the other property pages... and have included all the code references below.
Me.AddinName = "Contact Outlook"
Me.Description = "Provides connection between eActivated Portal Framework and Microsoft Outlook"
Me.FolderPages.Add(Me.pgeCalendar)
Me.FolderPages.Add(Me.pgeContact)
Me.FolderPages.Add(Me.pgeTask)
Me.FolderPages.Add(Me.pgeMail)
Me.Images = Me.ImageList1
Me.Namespace = "ContactOutlook"
Me.PageTitle = "eActivated"
Me.PageType = "ContactOutlook.CommonPage"
Me.RegisterForAllUsers = True
Me.SupportedApps = AddinExpress.MSO.ADXOfficeHostApp.ohaOutlook
Nothing is in the CommonPage constructore - it simply shows a couple of textboxes which access GetSettings (7 statements) in the load - but are wrapped in Try-Catch statements.
for example: GetSetting("eActivated", "ContactManager", "Contact-Create", False)
regards,
Dave
p.s. I just upgraded to the new version and the error is still present. |

I found the bug - and I believe it would be something you should resolve on your side but you can decide - let me explain more.
When the property window loads - it is common for developers to place GetSettings code in the Load portion of the form for the property page to restore settings placed in the registry.
The error occurs when the code is setting properties of controls, like dropdowns, checkboxes and textboxes. Since I place a function call to OnStatusChange() when a value changes - apparently when the property page is loading it causes the Add-In to report an eror which can not be captured.
I resolved this by placing a boolean IsLoading - and escaped the function call until after the Load function is done.
p.s. It doesn't happen with all controls - so I have to assume it does not trigger the onchange event for every control when setting value.
regards,
Dave |

I narrowed it down to controls which have a setting set in design time -
for example
textbox.text = "2"
Causes the Add-In to throw the error when first launched |
