Not that trivial this. You can create an AppDomain easily enough (CreateDomain method on static AppDomain if I remember rightly). Not sure how you inject your codedom stuff in there, but I'm sure there's examples on the net.

You then need to marshal your calls to the stuff in the new app domain. You'll probably need to create a stub class in the new AppDomain and derive from MarshalByRefObject to do this.

You can dispose of an AppDomain by calling Unload.

Make any sense?

Is there a WMI namespace, class and properties to get the time on a machine?
Thanks

Look at this[^].

Did you try even once to find the answer yourself?

Hi,

Try Win32_LocalTime, or Win32_UTCTime and Win32_TimeZone.

System.TimeZone for the current time zone.
DateTime.Now for the current time.
Anything else?

hello,

I use Microsoft.Office.Interop.Excel to creat excell file-I create it and in the end of the work with it i close it using
Microsoft.Office.Interop.Excel.Application ExcelApp
But the problem is that even after i close the application the excell still appears in the task manager(in processes).
How can i kill it in the program (when i finish working with excell)?

I did it this way :

ApplicationClass app = new ApplicationClass();
Workbook workBook = app.Workbooks.Open(filename, 0, true, 5, "", "", true, XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);

...

app.Workbooks.Close();
app.Quit();
Marshal.FinalReleaseComObject(app);

It doesn't help.
I still have the process of EXCELL running (in task manager)

Does anyone know what the problem may be?

Have you tried to release the Workbook, Worksheets, Ranges etc? The below works for me. I finally force the Garbadge collector to collect.

System.Runtime.InteropServices.Marshal.ReleaseComObject(objRange);
System.Runtime.InteropServices.Marshal.ReleaseComObject(objSheet);
System.Runtime.InteropServices.Marshal.ReleaseComObject(objBook);
System.Runtime.InteropServices.Marshal.ReleaseComObject(objExcel);
GC.Collect();

These work fine for me.

Excellence is doing ordinary things extraordinarily well.

I don't have excell range object
i only do objsheet.getrange.... or something like that
so i did the ReleaseComObject only to the application (objexcel), the sheet and the book.

Anyway,
The program still doesn't release the Excell process and i have it in task manager. What can be the problem?

I want to copy a font file to the fonts directory on windows vista, but currently i fail to get the right permissions.
Everytime I try to copy the font from its current folder to the font-directory (c:\windows\fonts) I get an "UnauthorisedAccessException"

My code looks like this at the moment:

            if (System.IO.File.Exists(fontPath))
            {
                FileIOPermission f2 = new FileIOPermission(FileIOPermissionAccess.Read | FileIOPermissionAccess.Write, "C:\\Windows\\Fonts\\");
                f2.AddPathList(FileIOPermissionAccess.Read | FileIOPermissionAccess.Write, fontPath);

                if (SecurityManager.IsGranted(f2) == true)
                    MessageBox.Show("Its fine!!");
                else
                    MessageBox.Show("No Permissions");

                try
                {
                    f2.Demand();
                    MessageBox.Show(fontPath);
                    System.IO.File.Copy(fontPath, destination);
                    //AddFontResource(fontPath);
                    //SendMessage(HWND_BROADCAST, WM_FONTCHANGE, (IntPtr)0, (IntPtr)0);

                }
                catch (SecurityException se)
                {
                    MessageBox.Show(se.ToString());
                }
                catch (UnauthorizedAccessException ex)
                {
                    MessageBox.Show(ex.ToString());
                }

            }
<pre>

Thanks for your help

Do you have rights to access the Fonts folder?
Which line throws the exception? That would help knowing where the problem is.
