EDraw Office Viewer Component contains a standard ActiveX control that acts as an ActiveX document container for hosting Office documents (including Microsoft Word, Microsoft Excel, Microsoft PowerPoint, Microsoft Project, and Microsoft Visio documents) in a custom form or Web page. The control is lightweight and flexible, and gives developers new possibilities for using Office in a custom solution.

The control is designed to handle specific issues that make using ActiveX documents from a non-top-level host window difficult, and serves as a starting place for constructing your own embedded object file viewer or editor as an ActiveX control.

It is a great solution for companies wishing to display read-only Word document data and Excel sheet to their employees while restricting modifications to the underlying data. You can play the powerpoint file in the same window. You can also display password protected Word documents without supplying passwords to your users - keep your confidential data safe and secure! With the office ocx it is easy to upload or download file between server and client via HTTP/FTP.

It can be easily integrated into applications written in languages that support ActiveX control such as Visual C++, Microsoft Internet Explorer, Visual Basic, Delphi, C++ Builder and .Net languages to view Office files inside their main solution, and give them programmatic control over the document while it is embedded.

Word 2007 File Seems To Be Deleted When You Open And Save It Using DSOFramer.

If you are using DSOFramer sample to host Office Documents, whenever he tried to open and save Word 2007 documents in this manner, guess what !! the file seems to be deleted !

Because the DSoFramer are moving the file to a temporary directory and then while saving it we are saving the changes in it.  Mostly you will lost the files if you are using Word 2007.

These don’t occurs in EDraw Office Viewer Component.
