I 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.
The following code causes a "Warning" that Variable is used before value assigned.How do I restructure this Try/catch to eliminate error on the myreader.close command in the Catch part? Code appears to work fine but I dont like Warnings. [code]

I 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.
View 1 RepliesI was using the following to provide more information on a common exception that can occour in a piece of my code, the only problem is this errors if an exception is generated that has no InnerException message.
Catch ex As Exception
'MessageBox.Show(ex.Message) 'If there is no InnerException.
MessageBox.Show(ex.InnerException.InnerException.Message)
End Try
Is there a better method of doing this?
I 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. I found the code on this forum, I think.The procedure works fine, but I can't use error handling with it.I call the procedure from a button click event. I put the procedure call in a try/catch block, and the application won't build, with the following error.

I am adding data to a database table using Entity Framework. When adding a duplicate Primary Key I get an exception in InnerException.Message that reads "Violation of PRIMARY KEY constraint 'PK_StudentID'. Cannot insert duplicate key in object 'dbo.Students'. The statement has been terminated. "However, what I want to do is to rephrase this error message for the end user, but also save this exact message with the table name and column name to my logs for later. Essentially, I want to rephrase the error message to "You cannot have a duplicate entry for Student Identification Number. Please enter a new value."I have tried to inherit from System.Data.UpdateException and put an if check to see what the innerexception.message reads, and then change it accordingly. That did not work.

View 11 RepliesI have a form with many textboxes. When the user exit, I ask him if he wants to save it, and if so, I save all data into text (INI) file.I'm looking for best practices how to know if the user changed something with any of textboxes?I know I can use 'change' event for each textbox, and use some global boolean variable to catch it. But since I have dozens of textboxes,I'd like to know if there is any better way?

Is there a way to catch ALL errors of the program?
Purpose: The idea is to catch all the errors of the program, load errorform which basically just says "A Error Was Detected" (Which I have already designed). Then send a web request to a formmail.php file with the said error (which i have already done).
In short: I need a way to catch ALL errors, and get the error string that it gave.

I'm creating a database using Access 2007 and Visual Basic 2008.
I'm using the try and catch exception handler in my project. this try and catch are inserted in the Save Record button. here is the code snippet of my try & catch:
CODE:
My problem is that, whenever i add a new record and clicked the Save Record button, the msgbox "Data Update Failed" popped out. But when i recheck, the newly added record was actually successfully saved in the database.
Is there something wrong with my code? The new record is inserted in the database but why does the "Data Update Failed" msgbox was popped out instead of the "Data Saved" msgbox?? I've tried many times but i still cant figure this out. please help.
How do i catch the exception, write to log and then get back into the loop?[code]i want that app keeps running although an exception is thrown.
