PRB: "&" in Controls Does Not Work as Expected

ID: Q103682

The information in this article applies to:

Microsoft FoxPro for Windows, versions 2.5 and 2.5a

SYMPTOMS

The ampersand (&) character will not display in some controls and instead will show the next character as being underlined. For example, the following procedure works differently in FoxPro for Windows and FoxPro for MS-DOS:

1. In a new screen, add a popup object. In the Popup Prompts box, type

   the following three prompts:

      This & That
      Tom & Jerry
      Curly & Moe

2. As soon as you assign a variable name and choose OK, you will see

   the popup prompt displayed as

      This _That

If you select "This _That" so that it drops down, you will then see "This & That" as well as the other correctly displayed prompts. However, as soon as you select a prompt, its display will return to being an underscore and no space instead of the &.

The same result occurs in FoxPro versions 2.5 and 2.5a for Windows. This behavior does not affect any version of FoxPro for MS-DOS.

CAUSE

This behavior occurs because of a limitation of the Windows environment. Similar behavior will be exhibited in other Windows-based applications such as Visual Basic. This behavior is by design, and changing this behavior would make FoxPro for Windows behave in a manner inconsistent with other Windows-based applications.

RESOLUTION

To display an ampersand character in Windows, use a double ampersand (&&). In some cases, you can use the following procedure:

1. In the Screen Setup Code snippet, type:

      m.myvar = "This &"+"& That"

2. In the Popup Prompts box for the list box control, type "&myvar"

   (without the quotation marks) instead of "This & That".

   NOTE: You cannot directly type

      m.myvar = "This && That"

   because FoxPro will assume that everything after the double
   ampersand is a comment and return an error.
