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
View 7 Repliesin 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()?
View 3 RepliesSimple 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?
Nothing is printed in my debug output window anymore.
Debug
.Print does nothing.
"Debug > Output" shows empty Output window.
Note: "Tools / Options / Debugging / General / Redirect all Output" is checked.

I am using Visual Studio 2010 Professional in trial mode... and suddenly the Output window won't show my Debug.Write() stuff. It had been showing it for the past month.I have been using the 2010 version for 30 days (after upgrading from Visual Studio 2003) in trial mode. I just renewed the trial for the extra 60 days, and the "About Visual Studio" window says I still have 59 days left.
I have verified that the application is running properly, without errors. When I purposely generate an error, the Output Window properly shows the error and the stack trace I've already checked my Build>Configuration... it's in "Debug" mode, not "Release". The Debug.Write() text is not going to the Immediate window, either.One other point, I tried running the same application in the Visual Studio 2010 Express Edition, and it complained that it could not debug the specified code, though it did properly build it so that it would run in the build. Could Visual Studio 2010 Express have modified something in my project files to disable the debugging output?
Can anyone explain the following immediate window behavior:
Debug.Print mDb.DatabaseOptions Method arguments must be enclosed in parentheses.
Debug.Print(mDb.DatabaseOptions)Value of type 'DatabaseOptions' cannot be converted to 'String'.
? mDb.DatabaseOptions
{Microsoft.SqlServer.Management.Smo.DatabaseOptions}
AnsiNullDefault: False
UserData: Nothing
According to MS documentation The question mark (?) is an alias for Debug.Print This is clearly not 100% true, as the two statements exhibit differing behaviors in the example above. If it makes any difference, I am using the Express Edition of VB 2008.
When I add a debug.print line to my code, it doesn't send the output to the immediate window. I did a search of the forum for debug.print, and found the identical problem, but, the solution listed did not work for me. Basically it said to set the solution configuration to "Debug" as opposed to "Release".
View 3 RepliesSince reinstalling VS2010, it has not been displaying proper debug info. I don't think I changed any settings but I have had a hunt through the options and can't see anything I might have messed up. I have had a quikck search and other people seem to have had the same problem but no solution. I'm running Windows 7 x64 with latest updates, if that matters.
View 1 RepliesI tried using: dim x as double= 10.0 debug.print(x.tostring) in my Visual Studio 2005 program but it doesn't display anything in the immediate window. It works in my Visual Basic Express 2008 program. How can I get it to work in Visual Studio?
View 8 RepliesIn 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?
View 3 RepliesI 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 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)

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.
[Code]...
in vb.net i have some code that looks like this:
Imports System
Imports System.IO
Imports iTextSharp.text
Imports iTextSharp.text.pdf
[Code]....
i would like to see what the console is writing. how do i do this?
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?
Just trying to print all list collection in a simple routine, variable repeat over and over except for the different collection list:
Dim p2 As New clsTranReq()
p2 = x.Deserialize(objStreamReader)

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.
I'm just going to throw all my code in here in case there's something wrong with a piece of the code not in the "SelectName()" sub.
Module Module1
Dim selectednames As String = ""
Dim index As Short = 0
Dim inarray As Boolean = False
[code]....
Here's an image of what it does (I suppose you can see what went wrong)13 inputs, 3 outputs expected, only 1 output given.As from what I've figured out so far, it's doing the correct amount of loops etc. It's just as soon as it starts generating the "winner" for the 2nd game key it doesn't get a string value from namesarray.Also, why is
For x = 0 To totalnames - 1
Debug.Print("namesarray(" & x & ") = " & namesarray(x))

not giving me a debug output?
I have a project that the debug.print "something" function has stopped showing in the "immediate window", or any other window. This has been working fine.If I create a new project the "debug.print "something" works fine.I did have to do a uninstall/reinstall of VS 2010 yesterday maybe something changed.Is there a setting that tells "debug.print" where to print?

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.

View 2 RepliesI've created a SSIS script task for debugging: printing SSIS variables and their values. This is done with (a maybe restrictied version of) Visual Basic. Rather then creating a message box or writing to a file I'd like to write to the debug output of Visual Studio - or to some other window available in Visual Studio when running a SSIS task. Something like fprintf( stderror, "Hello world!" ) in C. I suppose I need to get the Stream Writer Object connected with the debug output. But how do I do this? I also tried Console.WriteLine() but this didn't succeed.

I was running Visual Studio 2008 on my computer went through a whole VB progamming course with no problems. I recently had to have my computer hard drive erased and reloaded with windows xp to eliminate a virus. When I got it from the shop Visual Studio 2008 had not been backed up so I reinstalled the Professional edition from my disc. I opted fo the recommended installation. Every thing seems Ok except when I put a debug.Writelie (" Hello"} in the code nothing appears in the immediate window when it is executed. If I go to the immediate window and type the same line and hit return the string appears in the immediate window. If I assign a value to a variable in the program and put the debug.writeline command in the code module nothing appears in the immediate window, but if I go to the immediate window and type debug. writeline (var) and hit return the value of var apppears in the immediate window. i went to the debug menu and selected windows then clicked on immediate but it didn't highlight or show check mark. When the project builds after start debugging the immediate window appears. In the help it talks about a trace listener and insertig a line of code in the compile command line.
