Accessing controls on an Outlook Explorer taskpane

Silly question, but from the AddinModule.cs code, how do I get access to the dialog controls in the task pane I have created within Outlook. It is a task pane for the explorer.

I want to display the senders name in the task pane whenever I select an email. I have done the selection code and can get access to the mail properties, but cannot work out how to update the controls on the task pane.

Hi Mark,

You can use the following code:

//ADXOlForm2 code
public void Test()
    ADXOlForm1 form = (this.AddinModule as AddinModule).FindForm(CurrentOutlookWindowHandle);

//AddinModule Code
public ADXOlForm1 FindForm(IntPtr CurrentOutlookWindowHandle)
            for (int i = 0; i < adxOlFormsCollectionItem1.FormInstanceCount; i++)
                if (adxOlFormsCollectionItem1.FormInstances(i).Visible
                    && !adxOlFormsCollectionItem1.FormInstances(i).Active
                    && CurrentOutlookWindowHandle == adxOlFormsCollectionItem1.FormInstances(i).CurrentOutlookWindowHandle
                    return adxOlFormsCollectionItem1.FormInstances(i) as ADXOlForm1 ;
            return null;

Please have a look at the HowTo page of our web site. It contains the How to identify the form in an Outlook advanced form region in C# sample add-in project.
