Posted By:      Posted Date: September 02, 2010    Points: 0   Category :.NET Framework
Hi, Can anyone tell me why if I have a code like this     public class ServicioFaults : IServicioFaults     {         public double Dividir(double a, double b)         {             if (b == 0.0)             {                 throw new DivideByZeroException();             }             else             {                 return a / b;             }         }     } the service always steps into the else when I'm debugging? best regardsLuis Diego Rojas. http://icomparable.blogspot.com MCP, MCTS Biztalk Server

Every self-respected programmer should include exception handling techniques. Sometimes your application will generate an error. Regardless of who was responsible for this error, the programmer or the user, it is up to the first to include the necessary exception handling techniques to keep his/her program from crashing. The .Net environment provides useful techniques for avoiding disastrous errors such as try-catch statements and user-defined exceptions.

Global Exception Handling with ASP.NET

After your global exception handler has done its work, you'll want to redirect the users of your website to a friendly page that tells them that something has gone wrong, and then provide them with customer support information as well as a link back to your web application's home page.

Custom Editing Behavior for DataGridView TextBox Columns

For various reasons I'm using a DataGridView instead of a ListView, and while configuring the DataGridView to look like a ListView wasn't much of a problem, there's one thing that got on my nerves, which is the behavior of textbox cells in edit mode: It is much too easy to leave the edit mode accidentally, simply by pressing the cursor keys at the wrong time. For example when the text caret is positioned behind the last character of the textbox cell content, and you press the right arrow key

SQL Server 2005 Try and Catch Exception Handling

I'm pretty excited to see that there is some real error handling for T-SQL code in SQL Server 2005. It's pretty painful to have your wonderfully architected .NET solution tainted by less-than-VBScript error handling for stored procedures in the database. The big difference being the addition of TRY..CATCH blocks. Let's take a look:

Run Button Behavior: Suggestion/Bug


Note: This could be a bug or considered as suggestion. I am not looking for solution.

1: I have ImageWatermark.cshtml open and currently in focus.

2: I have Photo1.jpg selected in left Files workspace.

3: Now if I Click "Run", instead of opening ImageWatermark.cshtml it trys to open Photo1.jpg and it fails.

So ideally I would expect the "open file (ImageWatermark.cshtml) to run rather than running the selection from Workspace.

Word Automation - Multiple DCOM Errors/Behavior

Before I get started, I already know that Microsoft does not support and highly discourages server-based MS Office automation.  I've read a multitude of posts and smarmy "*wink*, here's a link" replies, so I'm looking for actual help here, not condescending reprimands.

That notwithstanding, here is my problem.  I have developed a simple method that will open a local Word document, modify some header information, and then save the document as a new file.  As expected, it works great as a console/windows app, but as soon as I went to ASP.NET, DCOM jacked my world up when accessing the app remotely from a different domain account (that has access to the ASP.NET app.  For reference, my method is shown below:


1    public static string ModifyAndSaveBuildDocument(string localFilePath, BuildDocumentType docType, string buildNumber, DateTime buildDate, string projectName)
2            {
3                try
4                {
5                    ProjectConfiguration config = (ProjectConfiguration)ConfigurationManager.GetSection("ProjectConfiguration");

"Exception from HRESULT: 0x800AC472"

Need help on these.Thanks in Advance.

WebControls.TableRow throws exception on Add()


I have the following method to strip hidden and user-specified columns from a gridviewrow and return a tablerow. 

    Private Shared Function StripHiddenColumns(ByVal gvRow As GridViewRow, ByVal ColumnsToExclude() As Integer) As TableRow

        Dim row As New TableRow
        Dim i As Integer = 0
            For Each cell As TableCell In gvRow.Cells
                If cell.Visible Then
                    If Not ColumnsToExclude.Contains(i) Then
                    End If
                End If
                i += 1

            Return row
        Catch ex As Exception
            Throw ex
        End Try
    End Function

However, when I run this code and hit the Add method for the TableRow,  I get an InvalidOperationException stating the Collection was modified; enumeration operation may not execute.  I've gotten this exception before, but usually it's because I'm attempting to modify a table that is databound.  This particular one is not, i am creating it.  Can anyone offer any insight? 

Thanks in advance.
