Error - Catch Cannot Catch Type 'Microsoft.Office.Interop.Outlook.Exception'
Mar 25, 2011I have a program in VB.Net that receives mails from Outlook, extracts attachments and inserts the attachments into a table through a query. I would like to put the query/queries in a Try/Catch block, but cannot do so as Outlook exceptions cannot be caught, and it gives me an error, and unless I put a very specific exception, I cannot catch it. Is there a workaround?
Edit:
Try
Catch ex As Exception
End Try
Exception is underlined and when I hover on it, it says: "Catch cannot catch type 'Microsoft.Office.Interop.Outlook.Exception' because it is not in 'System.Exception' or a class that inherits from 'System.Exception'". This is affecting all my other code which I'd like to put into a Try/Catch block.

Catch Log4net Exceptions / Use Try / Catch Approach
Jan 23, 2012I need to catch log4net exceptions (its own exceptions not app exceptions logged by it). I wish there's a way of doing it this way: [code] I have this code implemented and there's no errors in compilation but i force log4net to have an error (pointing to a non existing database in the config file) and nothing is threw.I've tried the listener aproach: [code] and it's writing the errors to log4net.txt, the forced ones i mean.This last aproach has a couple of drawbacks: it won't append every error to the file, if the error is the same it doesn't write it, i can't get the listener to write every error to that file, only one (I don't know how to fully configure the trace listener, it might be that). Thus it won't append the date and hour to every line wich is a necesity for me. Finally i can't give structure to it (xml). Even if the listener work i need to use the try/catch aproach, since i'm using ExceptionHandling from Enterprise library to log the errors in my app.

Feb 12, 2010I am using VB.NET 2005 to create a Windows forms application. I have a procedure named SendMail that creates an instance of Outlook.Application, to send an email from my application.

Try/Catch - "Don't Catch Exceptions That You're Not Willing To Deal With"
Apr 20, 2010A few weeks back in reply to a thread, I said then that it's sometimes worse to use a Try/Catch when there's nothing in the Catch!There are exceptions to that I'm sure, but too often the Try/Catch is used with a blank Catch that makes even the developer scratch their heads when the program crashes because they have nothing to go on (by their own doing).DevExpress (and I'm a big fan of their stuff) has a little three minute video that encapsulates that concept well and I thought that you all might enjoy watching it:[URL]

Vb Mail Order - Calculating The Percentages - Print Button Allows The User To Print The Form
Apr 8, 2011I have been able to do the exercise's in the first 2 chapters and half the exercise's in the third chapter of the text book (programming in visual basic 2008, Julia Case Bradley & Anita C. Millspaugh). but this one is making my head want to explode. please point me in the right direction with this.
Heres the problem. The company has instituted a bonus program to give its employees an incentive to sell more. For every dollar the store makes in a four-week period, the employees receive 2 percent of sales. The amount of bonus each employee receives is based upon the percentage of hours he or she worked during the bonus period (a total of 160 hours). The Calculate button will determine the bonus earned by this employee, and the Clear button will clear only the name, hours-worked, and bonus amount fields. A Print button allows the user to print the form. Do not allow missing or bad input data to cancel the program; instead display a message to the user.
Here's my code so far. its giving me the wrong results. i have tried many different ways,(hence the commented code) but I just dont know where im going wrong.
Public Class VB_Sales
Const BONUSHOURS As Decimal = 160

VS 2010 : Print/Print Preview Of Records From A Database/DatabaseDataSet Source?
Dec 14, 2011My instructor told us how to print documents and how to use databases. What the instructor did not mention is how to print or print a preview of records within a DatabaseDataSet. The book "Programming in Visual Basic 2010" does not explain how to print or do a print preview of Database Source records from within a form. The only thing I was told was to test the print document first before you try to do a print preview. Within a form I used a DataGridView to add, delete, and update the database. So now all I need to do is figure out how to print the updated records from the DataGridView and how to print a preview of the records within the DataGridView. So I hope my question is clear enough to give me assistance on how I can perform these two actions. Thanks this would be a great help, and since the class is online we can get assistance from any sources that we have.
View 5 RepliesC# - Use Case For Try-catch-finally With Both Catch And Finally
Feb 17, 2010I understand how try-catch works and how try-finally works, but I find myself using those (usually) in two completely different scenarios:
try-finally (or using in C# and VB) is mostly used around some medium-sized code block that uses some resource that needs to be disposed properly.
try-catch is mostly used either
around a single statement that can fail in a very specific way or (as a catch-all) at a very high level of the application, usually directly below some user interface action.
In my experience, cases where a try-catch-finally would be appropriate, i.e., where the block in which I want to catch some particular exception is exactly the same block in which I use some disposable resource, are extremely rare. Yet, the language designers of C#, VB and Java seem to consider this to be a highly common scenario; the VB designers even think about adding catch to using.
Or am I just overly pedantic with my restrictive use of try-catch?
EDIT: To clarify: My code usually looks like this (functions unrolled for clarity):
Try
do something
Aquire Resource (e.g. get DB connection)
Try
[Code]....
which just seems to make much more sense than putting any of the two catches on the same level as finally just to avoid indentation.
