I recently got a ADO.NET ebook in a chm format. I placed it in a folder structure C#/ADO.
When I opened the chm file content was not loaded. Problem was placing the chm file under a folder which contains a ''#' as in 'C#'. Actually chm files are called Microsoft Compiled HTML Help files and a proprietary format for online help files. It is related to html files. Problem is Since # means something specific in HTML helpviewer get confused. So don't place chm files in a folder where it's name contains '#'.
