  TITLE : OL98: Resources for Custom Forms and Programming



• I have created a custom form for my Contacts, Tasks, and so on, but it is not being used when I create a new item, when I open an existing item I had before I created the form, or when I create a new item. Why is my form not being used?
  
  To use a custom Outlook form, there are three steps you need to complete.
  
  First, publish the form in the folder or forms library where you will use it. On the custom form File menu, click Publish Form. The name of the form is also the "Message Class," which is important for the next two steps.
  
  Second, make this new form the default form for that folder. Using your right mouse button, click the folder and from the shortcut menu, click Properties. In the "When posting to this folder, use" list, click to select your custom form. Now new items that you create will use the custom form instead of the default Outlook form.
  
  Third, if you have any existing items in the folder that should use this new form, you must change the Message Class field in each of the items in the folder. The Message Class field of an item tells Outlook which form to use to display the item. You cannot directly change this field from an Outlook since it is considered read-only, but you can use VBScript or Automation code to change it.

• I am trying to do something but it doesn't seem possible. Is it?
  
  Outlook does not support a "full" object model, such as those in Microsoft Word or Microsoft Excel, so what you are trying to do may not be possible. Also, there may be other Outlook design considerations or limitations that may prevent you from using a desired approach in creating a solution.

• How can I disable the macro warning?
  
  If the form is not located in a trusted location, then Outlook will display the macro warning for your protection against potentially maliciously-written programming code, commonly called macro viruses.
  Disable the Macro Warning
  
  
  1. Open the form that causes the Macro Warning dialog to open.
  
  
  
  2. On the Tools menu, point to Forms and click Design This Form.
  
  
  
  3. On the Properties tab, click to uncheck Send form definition with LI.
  
  
  
  4. On the Tools menu, point to Forms, and click Publish Form.
  
  
  
  5. Close the form. It is not necessary to save the changes if prompted.

• I entered design mode to change a form I created, but now I can't select any of the controls on the form page. How come?
  
  This is a problem in Outlook 98 that you can workaround by switching to a different form page and then switching back to the page you wish to edit.
  
  For more information about this issue, please see the following article in the Microsoft Knowledge Base:

  TITLE : OL98: Cannot Select Controls in Design Mode



• I created a custom form and it looks great, but when I close and then re-open the item, or when I send the form to someone else, all of the information I entered into my custom controls is gone. Why does this happen?
  
  In Outlook, controls on a form are used to display information, but the information is actually stored in fields. Therefore, in order for the values of the controls to be preserved, the control must be bound to an Outlook standard or user-defined field.

• Using VBScript or automation code, how do I refer to a particular Outlook folder or a particular item in a folder? Or, how do I create a new folder or item?

• Why do some items in a folder have different icons? Why do some of the items in the folder have an abnormally large size? Why does the Message Class of an item change back to the default Message Class? How can I get a better understanding of how forms work in Outlook.

• When importing contacts from an external database, how do I map some of the fields to the user-defined fields that I have set up in a custom contact form?
  
  This is a limitation of the Outlook Import and Export Wizard. If you are familiar with Visual Basic programming, you can create a solution that programmatically imports or exports the information.

• How come when I export items from a folder, all of the items are not exported?
  
  Outlook 98 does not export items if they are based on a custom form, meaning that the message class field of the item is not the default message class for that type of item, such as IPM.Contact or IPM.Note.

• How do I set a default form for my Inbox?
  
  There is no direct way of doing this, but a workaround is to publish the message form to the folder, and then create a new mail item by clicking the form at the bottom of the Actions menu.

  TITLE : OL98: Using the New Contact Fields on a Custom Form



• When I use a custom control on my Outlook form, none of the events appear to work. Why?
  
  Outlook only supports the Click event for controls. Many controls are specifically designed to work with other events, and since these events are not supported by Outlook, the controls may not function in Outlook.
  
  To work around this situation, create a Visual Basic (VB) 5.0 ActiveX component (formally called an OLE server application). You start the component by using the CreateOject method in the Outlook object model. The component would display a VB 5.0 form with the appropriate controls, get the information that the user selects or types, and then automate Outlook to send any necessary information back to the Outlook form.
  
  This technique involves many aspects of programming. For information on how to create an ActiveX component, please see your documentation for Visual Basic 5.0.



• When I retrieve appointments and the folder has recurring appointments, the only items retrieved are the initial appointment. Why?
  
  You have to set the IncludeRecurrences property of the items collection to true. The default is false, which means that only the original appointment is returned. This is commonly an issue when using the Find or Restrict methods to return a collection of appointment items.

• How can I tell what version of VBScript a computer is using? Where is the documentation for VBScript? Why doesn't Outlook support Visual Basic for Applications?
  
  For more information about VBScript, please see the following article in the Microsoft Knowledge Base:

  ARTICLE-ID: Q182446
  TITLE : OL98: General Information About Using VBScript with Outlook



• How can I start another program or display a Web page from an Outlook form?
  
  You can use the CreateObject method in VBScript to automate an OLE-aware application.
