Failed To Create Component Constructor On Type Not Found

The UserControl is in a separate project than the form, but is in the same solution. I get two advantages: I know that when an object is constructed (without error/exception), my object is good. Fix the code (which usually means testing for IsNot Nothing before references an object properties...but could mean other things.) Also, sometimes I find that the control WILL load in INSTANCE_2 instead

Interview for postdoc position via Skype What's the point of repeating an email address in "The Envelope" and the "The Header"? The design environment requires a default constructor to be able to create an instance of your type. Go figure... There are often situations where you need to have a parameterless constructor, even though a parameterless constructor is not ideal.

The error occurs not at RunTime but at Design Time (or build time when I try to build). Failed To Create Component A Reference To The Component Already Exists In The Project The AceXtremeNET Control is actually my own project and is a part of the VS Solution. public IList MessageList {get{return _getList();} {set {_lostList(value);}} No code in the control is dependant on this property as it was meant purley as a get/set accessor. I'll be grateful!

Failed To Create Component Constructor On Type Not Found I've searched the web but most answers I found seemed related to having the control in a separate assembly. (Note that I found plenty of questions with the same problem I'm Your best bet is not to connect a database to a user control in design time, but dynamically link it during runtime.

If your custom control designer creates a glyph with the same bounds as the body glyph, it will obscure the underlying Behavior implementation associated with the body glyph. http://blackplanetsupport.com/failed-to/failed-to-add-entry-for-user-samba-ldap.html Refreshing the Design Environment After Making Changes to the Component or Designer When you make changes to the design-time aspects of a component, you must rebuild the component's project. It helps avoid forgetting to set a certain property. When I'm adding user control to form (using drag&drop) designer is showing following error: Failed to create component 'UserControl1'.

IIRC, the designer will call it so it's best not to have anything that does any external calls in it. –Austin Salonen Jan 26 '11 at 0:55 @Mathew: There amazing problem :D :D Add simple a new Windows Form Aplication to your solution..
