Prologue property

EmailReportButton.Prologue — Text

Special value available in formulas:

Item

EmailReportButton

The button this property is part of, enabling multiple checked items in the app designer to share the same formula and be updated all at once.

Consider the fields Field1 and Field2, which should only be considered to be valid if their values are greater than 4. Without using the Item value, the Valid property of Field1 would need to use the formula Field1 > 4Field1 > 4 and the Valid property of Field2 would need to use the formula Field2 > 4Field2 > 4.

Using Item, both formulas can read Item > 4Item > 4. This is useful if you have many fields and you want to be able to update their formulas all at once. To do so, click their check boxes in Calcapp Creator and make sure that a checked field is selected. Then, when you update a formula for one checked field, you update all the other checked fields too, which is a great timesaver.

Use Item in exactly the same way you'd use the regular name. Button1.VisibleButton1,Visible and Item.VisibleItem,Visible are equivalent, for instance.

The text that appears before field values. If the field values are part of an attached file, the text of this property also appears in the attached file. If the field values are part of the email body itself, this also applies to the text of this property.

The Epilogue property represents the text that appears after field values. The Body property represents the body text of the email.

If this property is not set, no prologue is used.

Entering formulas in the inspector

If you use the inspector to enter a value for this property, you can incorporate formulas by enclosing them within {{ and }} markers.

Behind the scenes, Calcapp converts an inspector value with formulas to a single traditional formula. You can view this formula, or edit it directly, by selecting the Prologue property from the drop-down menu next to the formula bar.

The examples on this page use traditional formulas, where text strings and other values are joined together using & and line breaks are produced using NEWLINE. To enter them in the inspector, be sure to enclose them within {{ and }} markers. Alternatively, enter them in the formula bar.

Refer to the documentation for the Body property for a complex example on how to produce a text string incorporating field values using a formula.

Example

IF(CriticalTemperature > 86, "Look closely at the
temperature readings below!")
IF(CriticalTemperature > 86; "Look closely at the
temperature readings below!")

Sets the text that appears before field values to "Look closely at the temperature readings below!" only if the value of the CriticalTemperature field is greater than 86.
