Description A dialogfunc implements the dynamic dialog capabilities.

Parameter Description

DlgItem This string value is the name of the user 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 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.

AccuTerm 97 Scripting Language Reference 37

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.) Note: When

the first item receives the focus there is no item that is losing

focus. In that case SuppValue is -1.

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.)
