ActiveX Control displays with a triangle/square/sphere in it.

[tvreddy]

Hi<br>I used an ActiveX control on web page. The control is registerd properly on the machine. But when the web page is diapyed, the control appears with a triangle/square/sphere. What could be the reason?<br><br>I could find a TechNote article from MSDN Q246034 and Q169438 but the problem resolution is not given. i.e., when does the control fails to appear and instead appears with a triangle/square/sphere.<br><br>Thanks and regards

The triangle/square/sphere only appears when the activeX component cannot be either found or instantiated correctly. <br><br>Check in your HTML Code that the CLASSID that is provided matches the classid for that control in your systems registry. <br><br>You code place a URL in the codebase parameter of the<br>object <br>&nbsp;&lt;Object CLASSIS somenumber CodeBase=&quot;C:\myOcx.ocx&quot; <br><br>this will point the browser towards you OCX. <br><br>Another possible reason for the failure is that if the ocx is compiled with Project compatability or with No Compatability then it is not backwardly compatable. A solution to this would be to re compile the OCX using a different name, change your HTML to reflect this change and the try again.<br><br><br>Hope this is of some help
