Hi, i have a regex code to get the time from a webbrowser but there is more than 1 time all in the same format.I need it to get the first time it catches, atm it gets the last time not the first?
Dim Regex As New Regex("d+:d+( [AP]M)")
Dim Matches As MatchCollection = Regex.Matches(WebBrowser1.DocumentText)
For Each Match As Match In Matches
TextBox1.Text = (Match.ToString)
Next

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]

View 6 RepliesI have this scenario: in a Sub I have a Try...Catch statement.Within that Try..Catch I call another sub.In that 2nd sub is also a Try...Catch.(see below for example).Now if an exception occurs in the 2nd sub's Try...Catch, which Catch gets excecuted? The 2nd one, the 1st one or both?
Private Sub sub1()
Try
..do stuff[code].....
If I throw an exception from within a catch, does the finally (from the catch) still execute? i.e.
Try
..some code with an exception in it...
catch ex as Exception

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 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.

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 am having an issue where I am using regex.Replace to replace part of a string. The basic idea is that I want to capture the beginning of the string then replace the end of the string with a value from code. For an example pretend I have a string that says "Test Number " followed by number and I want to increment that number. I capture the "Test Number " but when I try to concatenate that capture with the new number it treats the capture ($1) as a literal and replaces the entire string with $1[new number].
[code]...
This will output "We are on Test Number 2", as expected. how I can use a variable in the replacement string portion of the Regex.Replace when including a captured group?

Is there a way that when using a Try, Catch statment to give details of the sub routine and line that the error occurred? The reason I ask, is that there is a user in a different state who is using a tool, and he is getting some errors. He is getting an unhandled exception message. I can not seem to reproduce the error, and want to know where it is happening, other knowing that is has happened somewhere in the UpdateModelLists.

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.

I've been working straight since yesterday trying to get this to work. I'm a noob to RegEx and I've tested out about 5 different RegEx "builders" but each of them require you to navigate through the options to build the Regex...each of them has failed when I try to use them.Is there an application out there free/paid where you select the line you want to grab and the RegEx is auto generated from that highlight rather than having to try to build the line of code?
