Catch The CrLf Characters?
Jun 4, 2011
I have a situation where data in a field contains CrLf characters. Code has been in place for a couple of years and many records have been affected.Should I add code to catch the CrLf characters at the field level?Should I add code to catch and possibly correct the data before it is uploaded to SQL?Should I modify the upload to catch CrLf characters and possibly correct the data in the upload procedure?Whichever approach is more appropriate, how do I identify CrLf characters and then correct it.

I have a multi line text box that accepts Enter and tab as input, but this data needs to be saved without these characters. When the user loads this data, the text should be displayed as it was originally entered.In PHP, there is a function to replace line breaks and tab characters with and , and with \. I need a similar function here.

If I set the Text property of a RTB to a string that has CrLf's in it, it seems the RTB reduces the CrLf's to a single character & screws up the positioning to set the SelectionStart property.So, for example, if I know the position of a character in the original string & I set the Selection Start value to that position, the selection highlighting will be off by 1 character if the start position is preceded by a CrLf & off by 2 characters if preceded by 2 CrLf's, etc.So how can I determine the correct position to specify my SelectionStart value?

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.

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.

If I paste code snippets, or debug.print text with CrLF line ends, to the Immediate Window they line ends are ignored and the text appears as one long string. This is very annoying behaviour on the Immediate Windows part. How do persuade the Immediate Window to honor line ends?

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 had an interesting bug today when sending plain text emails from our system. We format messages like this: -1st something happened blab bla. -2nd something else happened blab blab blaa bla. Today we had an email that looked like this: -1st something happened blab bla. -2nd something else happened blab blab blaa bla $1000.00 -3rd Something happened. So above, we see that we lost the CrLf but only on the message that didn't have a period and ended in 0. I went through the code and found the CrLf is intack up until we send the email. I tracked the code down below, I am guessing it applies to C# as well:

Essentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.

I have a project converted from Visual Studio 2005 to Visual Studio 2010. It compiles and runs.
When I prune "unused references's from this project as listed by Visual Studio, the project fails to compile with the subject error message.
In particular one of the "unused refererences" is to "Microsoft.VisualBasic.dll". The IDE does not allow me to add back this particular reference.
What do I need to add back as a referenceto get this items?

A 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]

I need to create a console program that allows you to enter a string, of which is then outputted in reverse.

Not sure if too many people know this, but the following line will cause an error:
GroupName.Substring(0, 3) = "jt_"
....if the length of GroupName is less than 3 characters. I always thought it would simply return whatever characters in GroupName, but no, it errors. I must be thinking of the old VB6 days.So, I now have to change the code to:
If (GroupName.Length > 2) Then
If (GroupName.Substring(0, 3) = "jt_") Then
Note that the two comparisons need to be on separate lines. If they are on the same line, such as:
If (GroupName.Length > 2) and (GroupName.Substring(0, 3) = "jt_") Then then the code will still fail as the length command is executed at the same time as the substring command- which will cause the error when the GroupName length is less than 3.Just thought that those of us not aware of this should be!

I have two textboxes. I type in one of them and the text gets copied in real time into another textbox. There is one catch. I need to replace specific character with something else.
If I enter a quote " in textbox1, it has to be replaced with " in textbox2.
I started with something like the below code, but obviously this does not work (tried different stuff - this is for demonstration only). In the example below 'a' represents " , and 'b' represents "
Private Sub TextBox1_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.KeyUp
TextBox2.Text = TextBox1.Text
