According to this link, we should edit the registry key first if we use IE 7 and onword.

Added the .reg file as follow.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Word.Document.8]
"BrowserFlags"=dword:80000024

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Word.RTF.8]
"BrowserFlags"=dword:80000024

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Word.Document.12]
"BrowserFlags"=dword:80000024

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Word.DocumentMacroEnabled.12]
"BrowserFlags"=dword:80000024

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Excel.Sheet.8]
"BrowserFlags"=dword:80000A00

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Excel.Sheet.12]
"BrowserFlags"=dword:80000A00

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Excel.SheetMacroEnabled.12]
"BrowserFlags"=dword:80000A00

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Excel.SheetBinaryMacroEnabled.12]
"BrowserFlags"=dword:80000A00

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\PowerPoint.Show.8]

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\PowerPoint.ShowMacroEnabled.12]
"BrowserFlags"=dword:800000A0

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\PowerPoint.SlideShow.8]

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\PowerPoint.SlideShow.12]
"BrowserFlags"=dword:800000A0

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\PowerPoint.SlideShowMacroEnabled.12]

Please do backup the registry keys before changing.

*** It still works on office 2010. The webbrowser control can be the control in the Access form. 

However, it offers us a way to open office document in a winform. Somebody wants to show blank .doc document in a winform without showing the toolbar.  Maybe more efforts should be put into the following code line:

Object refmissing = System.Reflection.Missing.Value;
 axWebBrowser1.ExecWB(SHDocVw.OLECMDID.OLECMDID_HIDETOOLBARS, SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER,ref refmissing , ref refmissing);
