Purpose |
Retrieve a value from the user data area of a DDT control. |
Syntax |
CONTROL GET USER hDlg, id&, index& TO retvar& |
Remarks |
Each DDT control has a user data area consisting of eight Long-integer values which may be used at the programmer's discretion to save relevant data. CONTROL GET USER allows one of the values to be retrieved, based upon the index parameter value (1 through 8). hDlg refers to the dialog that owns the control. id& is the unique control
identifier
as assigned to the control with a
index& is the index number of the user data value to retrieve, in the range 1 to 8 inclusive. retvar& receives the Long-integer data value store in the nominated user data index. |
Restrictions |
Data in the user data area is lost when the control is destroyed. The data area is completely separate from the %GWL_USERDATA area maintained by Windows. |
