ID: Q182365

The information in this article applies to:

Microsoft Outlook 98

SUMMARY

You can customize Microsoft Outlook forms by using Microsoft Visual Basic Scripting Edition (VBScript) and/or ActiveX controls. This article illustrates how to add Outlook form controls and VBScript to an Outlook form. The example in this article uses the TextBox and CheckBox controls, and with VBScript programmatically populates those controls when you open the form.

Customizing the Form and Adding Controls

The following steps demonstrate how to customize a message form by making a new page visible and adding a TextBox and CheckBox control on the new page:

1. In Outlook, open a new mail message. On the Tools menu, point to Forms

   and then click Design This Form.

2. Click the (P.2) tab to select the second page of the form. On the Form

   menu, click "Display This Page." This will remove the parentheses from
   around P.2 and make the P.2 page viewable when the form is done.

3. On the Form Design toolbar, click "Control Toolbox" and on the Controls

   tab click the TextBox control. Drag a TextBox onto the form. Repeat
   the process to place a CheckBox on the form.

Binding a Field to Each Control

While you can manipulate the appearance of a control (color, font, etc.) with Advanced Properties, you must use a field to manipulate the value of a control. (Is the CheckBox checked? What text appears inside the TextBox?)

The following steps bind custom fields to each control. In this case TextBoxField is the name of the field bound to the TextBox control. CheckBoxField is the name of the field bound to the CheckBox control.

1. On the form, right-click the TextBox and on the shortcut menu, click

   Properties.

2. Under the Value tab, click New.

3. In the Name box, type TextBoxField. By default, the Type and Format

   lists should display Text.

4. Click OK and OK to close the Properties dialog box for the TextBox

   control.

5. On the form, right-click the CheckBox and on the shortcut menu, click

   Properties.

6. Under the Value tab, click New.

7. In the Name box, type CheckBoxField. In the Type list, click Yes/No.

   In the Format list, click True/False.

8. Click OK and OK to close the Properties dialog box for the CheckBox

   control.

Adding VBScript to Populate the Controls

The following steps programmatically change each control when the form opens by changing the value of the fields to which each control is bound. The value of TextBoxField changes to: "New text." The value of CheckBoxField changes to True. Therefore, the CheckBox appears checked.

1. On the Form Design toolbar, click View Code to display the Script

   Editor. On the Script menu, click Event Handler and click to select
   Open in the Events list and then click Add.

2. Type the following code between "Function Item_Open()" and "End

   Function":

   Set MyTextBoxField = Item.UserProperties.Find("TextBoxField")
   If MyTextBoxField.Value = "" Then MyTextBoxField.Value = "New text"

   Set MyCheckBoxField = Item.UserProperties.Find("CheckBoxField")
   If MyCheckBoxField.Value = 0 Then MyCheckBoxField.Value = 1

   NOTE: The names used in quotation marks are the names of the fields
   which you bound to each control. The value assigned to the TextBoxField
   field determines what appears inside the TextBox control. The value
   assigned to the CheckBoxField field determines if the CheckBox control
   has a check.

3. On the Script Editor's File menu, click Close.

Publishing the Form

Because the programming code in this example is in the Item_Open function, it executes when you open the form. You should publish the form so that you can see the results when you open a new form.

You can publish forms several ways. This example shows how to publish your form in your Inbox folder. Follow these steps to publish the form:

1. On the form's Tools menu, point to Forms and then click Publish Form As.

2. In the Look In dropdown, select Inbox.

3. In the Display Name box, type MyForm.

4. Click Publish to publish MyForm in your Inbox folder.

5. On the form's File menu, click Close. When prompted, "Do you want to

   save changes?" click No.

Using the Form

You published the form in your Inbox folder, so you must open your Inbox to use the form. Follow these steps to use the form:

1. Open your Inbox.

2. On the Actions menu, click New MyForm.

3. Inside the form, click the P.2 tab.

The TextBox should contain the text "New text" and the CheckBox should contain a check.
