DTBLEDIT

The DTBLEDIT structure describes an edit control to be used in a dialog box built from a display table.

Quick Info

typedef struct _DTBLEDIT 
{ 
     ULONG ulbLpszCharsAllowed; 
     ULONG ulFlags; 
     ULONG ulNumCharsAllowed; 
     ULONG ulPropTag; 
} DTBLEDIT, FAR *LPDTBLEDIT; 
 

Members

ulbLpszCharsAllowed

An offset from the beginning of the DTBLEDIT structure to a character string filter that describes restrictions, if any, to the characters that can be entered into the edit control.

The filter is not interpreted as a regular expression and the same filter is applied to every character entered.The format of the filter is as follows:

*Any character is allowed (for example, "*").

[ ]Defines a set of characters (for example, "[0123456789]").

-Indicates a range of characters (for example, "[a-z]").

~Indicates that these characters are not allowed (for example, "[~0-9]").

\Used to quote any of the above symbols (for example, "[\-\\\[\]]" means -, \, [, and ] characters are allowed).

ulFlags

Bitmask of flags used to designate the format of the character filter. The following flag can be set:

MAPI_UNICODE

The filter is in Unicode format. If the MAPI_UNICODE flag is not set, the filter is in ANSI format.

ulNumCharsAllowed

Maximum number of characters that the user can type into the edit box.

ulPropTag

Property tag for a property of type PT_TSTRING. The ulPropTag member identifies the string property whose data is displayed and edited in the edit control.

Remarks

A DTBLEDIT structure describes an edit control — an area on a dialog box that contains alphanumeric information. Almost all dialog boxes have at least one edit control. Edit controls can be modifiable by a user or read-only.

Edit controls can also be single line or multiline. Multiline edit controls typically have a scroll bar associated with them as shown in the following illustration.
