New:

  6. Problems

1) Dialog description

Button "Refresh" reload values. Button "Options" call form for setting autorefresh interval (ms). If value is 0, then autorefresh don't call. Button "Set properties" save changed value. Button "OK" close form.

Other controls with gray backcolor are read-only. Other controls with green backcolor are properties which you can set on for zero connaction or cursor.

2) Using

Cursor Properties:

SET CLASSLIB TO proper.vcx ADDITIVE
xx=CREATEOBJECT("_prop_cursor")
xx.Set(ALIAS()) && show properties for current alias (string)
xx.Set(SELE()) && show properties for current alias (number)
xx.Set(0) && show properties for zero alias

Connect Properties:

SET CLASSLIB TO proper.vcx ADDITIVE
xx=CREATEOBJECT("_prop_connect")
xx.Set(1) && show properties for connection with handle 1
xx.Set(0) && show properties for zero connection 

Running modal dialog:

SET CLASSLIB TO proper.vcx ADDITIVE
xx=CREATEOBJECT("_prop_connect")
xx.Show=1 && modal dialog (2 is modeless)
xx.Set(0) && show properties for zero connection 

Running dialog "As Top Level":

SET CLASSLIB TO proper.vcx ADDITIVE
xx=CREATEOBJECT("_prop_connect")
xx.AsTopLevel=.T.
xx.Set(0) && show properties for zero connection 

3) Zero connection and zero cursor

VFP can set properties for default cursor and connection - 0 (zero). VFP use these properties for new connections and cursors created by local view, remote view, SQLEXEC() and CursorAdapter.
