can u shed some light on this weird class instantiating err

Hi friends
i created class (class name is ctrHeight.VCX) with container,a label ,commandbutton a textbox in it.
when i add this to this a form from toolbar everything works fine.
but when i add this control thr code like following

thisform.AddObject('cnt','container')
thisform.cnt.visible=.t.

thisform.cnt.newObject('cntheight','ctrlheight','D:\VSSLocal\vip\ctrHeight.VCX')
thisform.cnt.cntheight=.t.

i am getting following error
"Error instantiating the object "txvalue" (actually it is a textbox)"
i am wondering what i am doing wrong here.

i just found when i add this control from toolbar and add another control thr code
like abv everything working fine???
what i am missing here??
many thanks for ideas

Just a guess but it sounds to me like there is a controlSource on the
textbox. When you add it to the form via the toolbar you are in design mode.
Adding it by code would indicate you are at runtime, therefore the tables
associated with the controlSource must be open prior to the textbox being
added.

"how can refresh textbox when the value in field changed without setting its
control source "

If I understand you correctly, if you want to display a new value from the
database just use
myControl.refresh
