Dialog Function

Description

A dialogfunc implements the dynamic dialog capabilities.

Parameter Description
DlgItem This string value is the name of the User Profile dialog item's field.
Action This numeric value indicates what action the dialog function is being asked to do.
SuppValue This numeric value provides additional information for some actions.

Action/Description

  1. Dialog box initialization. DlgItem is a null string. SuppValue is the dialog's window handle. Set dialogfunc = True to terminate the dialog.
  2. CheckBox, DropListBox, ListBox, MultiListBox, or OptionGroup: DlgItem's value has changed. SuppValue is the new value.
    CancelButton
    , OKButton or PushButton: DlgItem's button was pushed. SuppValue is meaningless. Set dialogfunc = True to prevent the dialog from closing.
  3. ComboBox or TextBox: DlgItem's text changed and losing focus. SuppValue is the number of characters.
  4. Item DlgItem is gaining focus. SuppValue is the item that is losing focus. (The first item is 0, second is 1, etc.)
  5. Idle processing. DlgItem is a null string. SuppValue is zero. Set dialogfunc = True to continue receiving idle actions.
  6. Function key (F1-F24) was pressed. DlgItem has the focus. SuppValue is the function key number and the shift/control/alt key state.
    Regular function keys range from 1 to 24.
    Shift function keys have &H100 added.
    Control function keys have &H200 added.
    Alt function keys have &H400 added.
    (Alt-F4 closes the dialog and is never passed to the Dialog Function.)
