C#: Generic Error Handling Routine (WinApp)

Just call the LogError method from any function within the catch block and pass the exception (ex) to this method...

public static void LogError(Exception ex)
{
string EventLogSourceName = "Application Name";
int EventLogErrorCode = "99";
string msg = "The application encountered an unknown error:";
msg += "\r\nExecuting Method: " + new System.Diagnostics.StackFrame(1, false).GetMethod().Name;
msg += "\r\nError Message: " + ex.Message;

EventLog.WriteEntry(EventLogSourceName, msg, EventLogEntryType.Error, EventLogErrorCode);
MessageBox.Show(msg, "ERROR", MessageBoxButtons.OKCancel, MessageBoxIcon.Error);
}

C#: Calculate Statistics of a Word Document

//***
//Label names are self Explanatory
//Stats include content from FootNotes and EndNotes
//Use objFalse = false instead of objMissing to exclude FootNotes and EndNotes
//***

Word.Document WDocument = Globals.ThisAddIn.Application.ActiveDocument;
object objMissing = System.Reflection.Missing.Value;

lblNumberOfPages.Text = WDocument.ComputeStatistics(Word.WdStatistic.wdStatisticPages, ref objMissing).ToString();

lblNumberOfParagraphs.Text = WDocument.ComputeStatistics(Word.WdStatistic.wd
StatisticParagraphs, ref objMissing).ToString();

lblNumberOfSentences.Text = WDocument.Sentences.Count.ToString();

lblNumberOfLines.Text = WDocument.ComputeStatistics(Word.WdStatistic.wdStatisticLines, ref objMissing).ToString();

lblNumberOfWords.Text = WDocument.ComputeStatistics(Word.WdStatistic.wdStatisticWords, ref objMissing).ToString();

lblNumberOfCharactersIncludingSpaces.Text = WDocument.ComputeStatistics(Word.WdStatistic.wdStatisticCharactersWithSpaces, ref objMissing).ToString();

lblNumberOfCharactersExcludingSpaces.Text = WDocument.ComputeStatistics(Word.WdStatistic.wdStatisticCharacters, ref objMissing).ToString();
