Debug.writeline Or Trace.writeline - No Output
Jan 27, 2012
in VS 2008, I started a new VB console project, using default options. I wrote this simple program:
Module Module1
Sub Main() Dim ArrayOfInts() As Integer
ArrayOfInts = New Integer() {1, 2, 3, 4, 5, 6, 7, 8, 9}
[Code].....
However, I cannot find the output from the calls to writeline. Not in the Output window, not in the Immediate window and not in the console output.
Or, do I need to do something extra to get these to appear?

What's the difference between Console.WriteLine() vs Debug.WriteLine()?

I have a fellow employee who is learning Visual Basic and in one of her assignments she is using the debug.writeline statement. Example: Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Debug.WriteLine("This line always prints") End Sub When you run the program, nothing prints to the Output window. I have tried it in VS2008 and VS2010. Brian Allison

This may be more of an OOP concept question, but here's what I'd like to do.I have an application that outputs debug information using System.Diagnostics.Trace.WriteLine so it can be viewed with DebugView.I'd like to override/extend (not sure of the proper terminology) this method to log the text to a file instead, or maybe in addition to the Trace output. This would allow me to write a new WriteLine method for my app, and I could leave all my other System.Diagnostics.Trace.WriteLine statements unchanged throughout the rest of the application.?

Simple question that does not seem to be covered: If I use a lot of Debug.WriteLine statements in my code, will they be completely absent in my production version?
I mean: Is the compiler smart enough to not emit any code for those calls? Or would I have to surround them by #if DEBUG..#end if directives?

In the past, perhaps versions of Visual Studio prior to the 2008 that I am using now, I would do something like this in my VB.NET code:System.Diagnostics.Debug.WriteLine("Message")
and the output would go to the output window.Now it doesn't. Something must first apparently be enabled.
If this involves "attaching a debugger", please explain how to do it. It seems to me that it should just work without too much of a fuss.Here's a video explaining the issue in real time and showing you all my settings[URL]..

If I have Debug.WriteLine method in my code, do I need to comment all these methods before producing the Release version? Or does the compiler just ignore them?

I have a vb.net application that uses threads to asynchronously process some tasks in a "Scheduled Task" (console application).We are limiting this app to run 10 threads at once, like so:
(pseudo-code)
- create a generic list of 10 threads
- spawn off the threadproc for each one
- do a thread.join statement for each thread to wait for the longest running one to complete.
What i am finding is that if the code called by the threadproc contains any "Debug.Writeline" or "Trace.Traceinformation" statements, the thread hangs. I can see the thread in the Debug - Windows - Threads window, and switch to it, but it highlights the debug.writeline statement and never gets past it. is there something special about the Debug or Trace statements that make them non-thread-safe? Any idea why this would hang things up? If I leave the debug statement in, the thread never completes. If I take the debug statement out, the thread completes in less than 5 seconds.

I have been searching for a way to format output using writeline/write (streamwriter)using RTF tags and wondering if there is a syntax for this, if it exists. I have not been able to find a resource which clearly explains how to "pretty" up output sent to a file.
The reason why I am asking is because I want to "print" results from my program into a file that, at the very least, would be centered, tabbed and even bolded where possible without requiring the user to go and futz with it. I think I saw that Crystal Reports won't work with VB 2010 Express and, quite frankly, just want to create a file with output.

I have a procedure that loops through the directories/subdirectories on a file server and sets the permissions. Procedure is called on a button click of a form.
I need to display on the form which directory is being processed. Similar to if we use the Debug.writeline which writes to the output in Visual Studio. I tried using a ListBox but it only displays the last one and only displays the last one once processing is done. I want to be able to display each directory name as it is being processed.
Psuedo code as follows:
For each dir in L drive
setPermissions(dir)
'display in ListBox dir name
lstProgress.Items.Add(dir.Name)
Next

Dim hex = "41"
Dim text As New System.Text.StringBuilder
For i As Integer = 0 To hex.Length - 2 Step 2
text.Append(Chr(Convert.ToByte(hex.Substring(i, 2), 16)))
[code].....
but yet this fails.. (the output isn't itself in a new line) what's the explanation for that?From what I know, doesn't System.Diagnostics.Debug.Writeline does something which looks like this:
System.Diagnostics.Debug.Write(input)
System.Diagnostics.Debug.Write("
")
so regardless of my input it should always have a newline char even if there is a terminating 00 char in my input?

I am trying to write some messages to a text file using debug.writeline("Message"). Here is the code.
Dim Tr As TextWriterTraceListener
Tr = New TextWriterTraceListener(System.IO.File.CreateText("Output1.txt"))
'Tr = New TextWriterTraceListener(System.Console.Out)
Debug.Listeners.Add(Tr)
Debug.WriteLine("Test Message")
I see the output1.txt file being created but nothing being written in the file.

In my case, I'd like to output to a ListView or TextBox or for that matter, any control which can accept text. For this purpose, I'd like to have a general purpose Trace/Debug listener which I can hook to in order to process the messages (convert to a ListViewItem or something) before outputting it. Is there any way I can achieve this or do I have to build my own Trace Listener? If it's worth noting, I run VS2010 ultimate & VS2008 professional. Solution should be in preferably be in VB.NET but C# is okay.

I probably have something misdeclared but can't find it. I'm trying to open a file to write data into and the last line in the code below gives the message "WritiLine is not a Member of ScriptingFileSystem.Object". I have something similar in another module that works. Maybe I don't have the inheritance correct? This is from VB 2005.
Here is the code

I am writing an array in a file with this loop.
sw.WriteLine("attributes")
For i = 0 To noatts - 1
sw.WriteLine(attName(i))
Next
This is creating weird results though.
[Code]...
Anyone know why could that be? In other parts of the file writeline works well. It only creates extra lines on that specific section. Btw: the file looks good if viewing by notepad, the extra lines appear when viewing in wordpad. Apparently that matters because when I reuse that file to read some values in my program, it crashes cause it reads those empty lines instead of the attributes.

It would be handy during debugging to have multiple consoles (not multiple monitors, which I already have). I am imagining something like Console.WriteLine(1, String1) which would send String1 to one console window 1 and Console.WriteLine(2, String2) which would send String2 to console window 2.

I have declared my variables As Decimal, and what I am struggling to do is to display these values to 2 decimal places in such a way so that they both appear on the same line of output. Here is the guts of the problem (noting I have two different versions of Console.Writeline...the second one does display on one line, but without two decimal places).

I'm working on a console application that needs to write a line until a certain value is met and than do the same backwards until another value is met.
The line need to be 51 spaces wide, start and end with the pipe ("|") character and have a cross ("X") character in between.
I can only define both the characters once.
The result needs to be something like this:
|X_________X|
|_X_______X_|
|__X_____X__|
|___X___X___|
|____X_X____|
|_____X_____|
And then from the last line on, go back to form a big X on the screen and start over again, going over and over until a key is pressed.
