I doubt that anybody else will make it; where did you get stuck?

Which video-link? That's not a standard part for a download-manager.
You'll need to explain a bit more on what you're trying to do, what you were expecting, and where you got stuck.

Do a search here on this site. There is a very good article on building your own download manager.

Assuming you have a question ongoing with him, then the correct thing to do is to reply to one of his comments. He will be notified of the reply and he may, or may not, choose to reply to you. If you are wanting to ask a new question, then you should just post a new question and you may get help from him, or you may get help from others who are equally as good, if not better, than him.

It's pretty easy to get in touch with SA - use the wrong word in a QA question, and he'll be in touch with you pretty quickly...

There is no way to chat directly with a member. If they have private email replies switched on for a message in the general forums, you can send a message to them. I will warn you though that this can be seen as incredibly rude - people help out voluntarily and they don't appreciate being approached directly. It's one of the reasons I switched it off - in one week I got nearly 60 requests for help writing projects.

I need to create excel file and email it once every month. I've got my windows service working. I've got standalone my excel file creation and saving without user prompt working. But when I try to create excel inside windows service, excel file isn't created at all without any error message in the event log. Below is my code. Can someone please enlighten me what goes wrong? Thanks in advance!
private void weeklyTimer_Elapsed(object sender, ElapsedEventArgs e)
{
eventLog1.WriteEntry("W event elapsed @ " + e.SignalTime);
createXLS(dirXLS_W);
}
private void createXLS(string dir)
{
string data = null;
Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
xlApp = new Excel.Application();
xlApp.DisplayAlerts = false;
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
eventLog1.WriteEntry("Xls worksheet created.");
xlWorkSheet.Cells[1, 2] = "Date";
try
{
xlWorkBook.SaveAs(dir, Excel.XlFileFormat.xlWorkbookDefault, misValue, misValue, true, false, Excel.XlSaveAsAccessMode.xlNoChange,
Excel.XlSaveConflictResolution.xlLocalSessionChanges, misValue, misValue);
xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();
eventLog1.WriteEntry("Excel file is saved under " + dir);
}
catch (Exception e)
{
eventLog1.WriteEntry("createXLS error: " + e.ToString());
}
releaseObject(xlWorkSheet);
releaseObject(xlWorkBook);
releaseObject(xlApp);
}
private void releaseObject(object obj)
{
try
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);
obj = null;
}
catch (Exception e3)
{
obj = null;
eventLog1.WriteEntry("Exception Occured while releasing object " + e3.ToString());
}
finally
{
GC.Collect();
}
}

And what about the debug messages? Are they written to the eventlog?

All I'm doing currently by brute force is putting eventLog1.WriteEntry at several stages of the code to check where the code stops working, using try and catch block and write exception to eventlog as in my code snippet. Now I've put all my creating excel file code into try and catch like below.
private void createXLS(string dir)
{
eventLog1.WriteEntry("In createXLS");
Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
eventLog1.WriteEntry("createXLS declaration");
try
{
xlApp = new Excel.Application();
xlApp.DisplayAlerts = false;
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);
eventLog1.WriteEntry("Xls worksheet created.");
xlWorkSheet.Cells[1, 2] = "Date";
xlWorkBook.SaveAs(dir, Excel.XlFileFormat.xlWorkbookDefault, misValue, misValue, true, false, Excel.XlSaveAsAccessMode.xlNoChange,
Excel.XlSaveConflictResolution.xlLocalSessionChanges, misValue, misValue);
xlWorkBook.Close(true, misValue, misValue);
xlApp.Quit();
eventLog1.WriteEntry("Excel file is saved under " + dir);
releaseObject(xlWorkSheet);
releaseObject(xlWorkBook);
releaseObject(xlApp);
}
catch(Exception e1)
{
eventLog1.WriteEntry("createXLS error 1: " + e1.ToString());
}
}
And this is the error I get. Line 218 is at
xlApp = new Excel.Application();
createXLS error 1: System.Runtime.InteropServices.COMException (0x80080005): Retrieving the COM class factory for component with

So what is the code on line 218?
Also write the dir to the log to make sure it is valid

line 218 is at

Written the dir to the log. It is a valid directory.

The problem sounds to me like an issue with the account that you are running the service under doesn't have access to the appropriate part of the registry. To test this out, set your service to run as a named user and then see if it works.
Note, I wouldn't recommend this as a permanent solution. Instead, I'd have the system admins create a dedicated locked down user for this service to run under.
