Defines a set of control properties common to some Microsoft Outlook controls.
The members offered by OlkControl can apply to most Outlook controls. OlkControl provides a class to which you can conveniently cast an Outlook control without resorting to reflection. Although OlkControl does not apply to Microsoft Forms 2.0 controls, similar properties are available to Forms 2.0 controls. For more information, see KB 180972: Additional Control Properties Available for Programming.
The following code sample uses the OlkControl class to enable automatic resizing of a text box control with respect to any resizing of the form. It uses casting in Visual Basic to allow the text box control to use the properties of OlkControl.
Sub ResizeWithForm() Dim myTextBox As OlkTextBox Dim olkCtrl As OlkControl ' Let the text box control use the properties of OlkControl Set olkCtrl = myTextBox ' Enable automatic adjustments of the layout with respect to the rest of the form olkCtrl.EnableAutoLayout = True ' Allow resizing the text box control horizontally and vertically with the form olkCtrl.HorizontalLayout = olHorizontalLayoutGrow olkCtrl.VerticalLayout = olVerticalLayoutGrow End Sub
