Security problem w/ VB.Net and Word/Excel on Vista 32bit

Hi, I have a VB.Net application that I have recently upgraded from
Visual Studio 2003 to Visual Studio 2005. The VB.Net app accesses
Word and Excel. When I run the newly compiled VB.Net app on the
Windows XP Pro system the app can interact with Word and Excel just
fine. I'm pretty certain I have the correct Microsoft Word 11.0
Object Library and Microsoft Excel 11.0 Object Library references.
All of my library references have Local Copy set to true.

When I run the app on a Vista 32bit system I get the following error.

Source: Microsoft.Offic e.Interop.Word
System.InvalidC astException {"Unable to cast COM object of type
'Microsoft.Offi ce.Interop.Word .ApplicationCla ss' to interface type
'Microsoft.Offi ce.Interop.Word ._Application'. This operation failed
because the QueryInterface call on the COM component for the interface
with IID '{00020970-0000-0000-C000-000000000046}' failed due to the
following error: could not be found. (Exception from HRESULT:
0x80030002 (STG_E_FILENOTF OUND))."} System.InvalidC astException

Now for the odd part. On the Vista system when I right-click on the
new app .exe and select 'Run as administrator' the app runs without
error and can interact with Word and Excel with no problem. When I
just run the app as myself (I am a member of the local administrators
group) I get the exception.

This seems like some sort of conflict with new security in Vista.
Anybody got any ideas?

Thanks,
John

It's called setting up a Vista UAC Manifest that an application/program will
use to present the proper credential such as Run As Administrator to Vista
so that Vista will allow the program to run with the proper credentials
needed.

Look it up and find out how to create a .Net solution that uses the Vista
UAC Manifest -- use Google.

I have made a fundamental error in design and ignored security until the end of the project. This is largely because the whole process was a steep learning curve (helped enormously by this group) and I didn't know when I started (and still don't really understand), how to implement security. I have an application in two parts: - the first part is used by a number of people on standalone laptops who collect information about patients. ...

Dear all, I installed Vista SP1 on my Vista x64 Enterprise machine. Now my Visual Basic 2005 (.Net 2) does not behave correctly. It appears that 'for loops' have a problem of some sort.

Everything works perfectly on WinXP. Anyone has any idea if...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
