SUMMARY

The format of the data entry @ ... GET edit region for a telephone number can be controlled programmatically with a mask defined using the PICTURE clause, or it can be controlled in the Screen Builder or Form Designer by specifying the picture in the Format edit region of the Field dialog box. The examples shown below illustrate both methods.

MORE INFORMATION

The @ ... GET ... PICTURE clause provides the means of specifying a mask to control the format of data entered in a GET object in a window. The following paragraphs show examples of parameters of the clause that create a mask to control the format of a GET for entering a telephone number. These parameters provide all the customary nondata formatting characters (such as parentheses and dashes), but allow FoxPro to store only the numeric information so that the number is saved in just ten characters, either as a character field or as a numeric field. The parameters can be included either in a hard-coded "@ n.n GET <variable/field name> PICTURE ..." (without the quotation marks) command or they can be included in the Format box in the Field dialog box of FoxPro's Screen Builder.

FoxPro 2.x for Windows Examples

For example, if the telephone number is to appear on the screen as follows (these numbers are for example purposes only)

(213)123-1234

the PICTURE clause should appear as follows:

PICTURE "@R (999)999-9999"

The string to enter in the Format box in the Field dialog box is:

@R (999)999-9999

Likewise, if the telephone number is to appear as follows

213/123-1234

the mask should appear as follows:

@R 999/999-9999

Visual FoxPro for Windows Examples

For example, if the telephone number is to appear on the screen as follows (these numbers are for example purposes only)

(213)123-1234

Set the Format property to "R" (without quotation marks) and the InputMask property to the following:

(999)999-9999

Likewise, if the telephone number is to appear as follows

213/123-1234

the Format property should be "R" (without quotation marks) and the InputMask should appear as follows:

999/999-9999

Notes

  • The "@" symbol defines the characters following it as belonging to the PICTURE clause.
  • The capital letter "R" and the space character following the "R" display a format mask in an @ ... GET editing region. These mask characters are not stored in the field when the @ ... GET editing region is exited.
  • The mask characters shown in the above examples, other than the digit 9, are not stored in the table. These characters are skipped over when keys are pressed during data entry.
  • The nines (9) in the mask allow only digits to be entered in character fields; in numeric fields, they allow digits and signs to be entered. Since a telephone number consists of digits but is seldom used in arithmetic operations, the database field holding the number should be defined as a character field. Only digits in the range from zero through nine are accepted in the edit region.
