hi,

   In one of my Module i am using DotNetNuke.Modules.HTML dll it is working fine in DNN3.x and DNN4.x but in DNN5.x i am getting error like

   "unable to load assembly DotNetNuke.Modules.HTML".

Over all i want to access "HtmlTextController"  class

 below is the code:

Dim

objHTML As New HtmlTextControllerDim objText As HtmlTextInfo = objHTML.GetHtmlText(EditModuleId)

My guess is that is related to the change in 4.5.0 to merge the text/html module into the core framework and not as a module.

I am not 100% sure as I don't have DNN installed on the PC that I am currently using, but try looking at

DotNetNuke.Modules.HTMLEditorProvider

That might have what you are looking for.  Otherwise I'll have to do some digging when i get home, or maybe someone else here will know.
