I was wondering if it was possible to change the default variable name that shows up in the auto-complete for a Try-Catch block. It populates as:
Try
Catch ex As Exception
End Try
I want it so it populates as:
Try
Catch excError As Exception
End Try
What I want to do is change the default Try Catch template so that includes the basic error handling code that is required by my company. I have tried to find the place where we can change this, but I only appear to be able to find out how to do things like change the class template and things like that rather than bits of code.

Notice the catch (Type) instead of catch (Type myVariable). Is this possible with VB.NET, or do you always have to declare a variable when you catch exception types, like so:

View 1 RepliesWe are running on a Windows Client Platform (generally WinXP) in niche industry program that runs in a 640x480 window back to an AS/400 server. To reduce errors I want to watch for when the title bar of the program changes. Then I need to capture the keyboard entries to validate. I'll then make sure each of the entries is valid since the archaic program does no validation. I'll can then do a pop-up then warning the end-user if errors occur and to reduce/eliminate the exception reports.how can I capture the event of the application title bar change = 'string' that I need? API call? Aiming to do this in VB unless another would be notable cleaner.

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]

The code below works for the class that I hard coded "XCCustomers" in my RetrieveIDandName method where I use CType. However, I would like to be able to pass in various classes and property names to get the integer and string LIST returned. For example, in my code below, I would like to also pass in "XCEmployees" to my RetrieveIDandName method. I feel so close... I was hoping someone knew how to use CType where I can pass in the class name as a string variable.
Note, all the other examples I have seen and tried fail because we are using Option Strict On which disallows late binding. That is why I need to use CType.I also studied the "Activator.CreateInstance" code examples to try to get the class reference instance by string name but I was unable to get CType to work with that.When I use obj.GetType.Name or obj.GetType.FullName in place of the "XCCustomers" in CType(obj, XCCustomers)(i)I get the error "Type 'obj.GetType.Name' is not defined" or "Type 'obj.GetType.FullName' is not defined"

Why are static variables set equal to 0 in the declaration when 0 would be the default value of the numeric variable anyway when it's first declared? Not including the "=0" in the static declaration seems to work with no problem.

View 2 RepliesI 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.

I have Excel 2003 and 2007 loaded on my computer. When I open an Excel file, it is defaulting to 2003. How do I check to see what the default program is for opening xls files and change this to 2007 in my code? I have already done the following manually:
1-Open My Computer
2-Go to Tools --Folder options
3-Click the File Types tab
4-Scroll down to the XLS file type and highlight it

However I am not convince that its defaulting to Excel 2007 when I run projects in VB as I am seeing the "File Conversion" prompt when file are open.

View 7 RepliesI am inheriting my own DataGridView (say MyDataGridView) from the standard DataGridView control. What I want is that certain properties of MyDataGridView should have a different default value than what its base have. For example, AllowUserToAddRows, AllowUserToDeleteRows, AllowUserToResizeRows properties should have the default values of False; so that when I drag MyDataGridView into a form in the IDE, the default values shown in the properties grid should be False. Later on, if I want to change them to True from the grid, they will be set accordingly.
