Take the tour ×  I've created a windows control that needs to
run in a web page. I don't have any idea on how to fix this.. it
replies "the control type was not specified or the specified
value type could not be found". I have pasted a copy of .dll of
my windows control on my web project. here is the code I've
used.   <object id="myName"
classid="http:ACEBARCODE.dll#ACEBARCODE.ACEBARCODEGENERATOR"
width="500px" height="200px" />  please help me. thanks in
advance:)  btw I use I run it on Firefox... I try this on IE but
still no show.  share|improve this question Is this a winforms
