Hi, I'm ussing c# and I'm opening an Exceldocument in a webbrowser like:

this.Navigate(url,NavigateOptions.None,null,null,null);
Then in NavigateComplete I get the Excel Application.
        public void axWebBrowser1_NavigateComplete2(object sender, AxSHDocVw.
DWebBrowserEvents2_NavigateComplete2Event e)
{
Object o = e.pDisp;
Object oDocument = o.GetType().InvokeMember("Document",BindingFlags.
GetProperty,null,o,null);
           
oApplication = o.GetType().InvokeMember("Application",BindingFlags.
GetProperty,null,oDocument,null);

m_Excel=(Excel2.Application)oApplication;

All works fine and the xls is shown,but Im not able to save any changes made
in the document,it throwns the exeption 0x800A03EC.

Has anyone any ideas to what causes this?!?
Any help would be sooo great!
