WebBrowser class
in [CSharp]
|
From: Laurent Lequenne on 15 Apr 2006 14:10 Hello All, I'm currently developing a free windows Scrabble (in french :)) application that uses extensively the WebBrowser class of NET 2.0 for configuration, and data browsing. It works 100% on my machine, with the WebBrowser Class, and the Microsoft.MsHtml component. I can access all elements on the pages through the events, I can change some parts. Everything is rendered with XSLTs and changing directly the document through the msHtml thing. But apparently, it works only well on both of my machines :-) When I deploy the application, Enabling / Disabling controls does not work and when the application try to access a SelectElement the users got that error : Unable to cast COM object of type 'System.__ComObject' to class type 'mshtml.HTMLSelectElementClass'. COM components that enter the CLR and do not support IProvideClassInfo or that do not have any interop assembly registered will be wrapped in the __ComObject type. Instances of this type cannot be cast to any other class; however they can be cast to interfaces as long as the underlying COM component supports QueryInterface calls for the IID of the interface. The Microsoft.MsHtml is copied with the application and all users have a correct installation, as it is the only thing that doesn't work does anyone knows what I have to do, to make it work on machines that shouldn't be loaded with Visual Studio, as it's the only difference I can figure out with my machines and users machines ? Thank you Laurent
From: VJ on 15 Apr 2006 15:01 I believe the Microsoft.MsHtml is a COM component.. Try registering it when installing it. If you are using VS Packaging.. there is a option to do this for a single file in the properties windows. Check the properties, the property name is pretty obvious..

From: Laurent Lequenne on 15 Apr 2006 15:13 Euh I don"t thinkk so, it has been found in the NET components into the references of my project, but maybe it's just a wrapper class, and it's dependent of another DLL ?

From: VJ on 15 Apr 2006 15:34 uhmm.. yes sorry, I just saw that myself... If you are using the browser object or the MS Browser control, that will its own set of Dlls..uhmm lets see.. Can you tell me how you are building your setup project?., Just like a including a Project Output into VS.NET setup project and then building?

Hello VJ :-) No I add the Microsoft.mshtml.dll in addition of the project output and other things. The application is running well everywhere for reading/settings values in the forms of the browser. But it does not disable the controls, and I can not access the options of a select control, however the value can be read from the value of SelectElementClass. Things that are working well on my computer.
