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?
What's the difference between Console.WriteLine() vs Debug.WriteLine()?
View 3 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?
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?
View 3 RepliesI 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 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 VERY perplexing problem in both Visual Basic 2008 & 2010 Express. When I try to debug my project, the program runs without stopping at any breakpoints. If I start the debugging by clicking on Step In, the application just starts running.The Immediate Window has the following line, when I start debuging with Step In:Step into: Stepping over non-user code 'QBPOExport.GlobalFunctions.Main' (QBPOExport.GlobalFunctions.Main is my startup task)
View 2 RepliesI 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've just installed Visual Studio 2010 Express on a new laptop running Windows 7 64 bit.
When I debug a VB project and an error is encountered a message is sent to the immediate window, but execution is not halted. This means I am unable to look at variables etc.
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 have developed an application in vb.net.I use a dll that I build as part of a different project in my solution. For some reason I don't get the full functionality of my application with the dll built as a "release" version, but it does work if the dll is built as a "debug" version (that's a whole different problem).I don't have a problem, for now, using the debug version.However, the problem I'm having is I am trying to deploy the application to another system and if I deploy the debug version of the dll I get a runtime error (see below).I have the .net Framework installed. I'm just wondering what has to be installed in order to allow me to use the debug version of the new system? [code]When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.
View 1 RepliesI 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 created a vb dll using class library in visual studio 2010 [URL]... I have accessed this Dll in Excel VBA by referencing it through (Tools>>Reference)...I obtain different results when i run my program from Excel and when I run it from Visual Studio during debugging (here the debugging starts Excel as an external program). The results are exported by the dll function as a structure array ( The required values
are in double format in a constituent 1D array). The difference is as high as 5%.
What might have caused this difference? Could someone please help me with this?

View 4 RepliesI upgraded to VB2010 from VB2008 early this year and have been working on a Windows Service which I am now debugging. When I was using VB2008 in Windows XP SP3 I would put a Stop statement in the code and when execution got to it a dialog would open asking if I wanted to debug it using a development environment listed in a provided list. The list contained the VB2008 VS IDE which I selected which would in turn transfer me to the IDE in debug mode. I was very happy with this setup.
Now I am using VB2010 with Windows 7 and when the execution reaches the Stop statement the service just stops. It no longer offers the choice and ability to "jump" into the development environment via the dialog that I mentioned.[code]...
I've received a project from a friend and the Debug platform is set to "Active (Itanium)",so I changed it to x86, saved, closed the "My Project" window, and debugged. Same message:Error while trying to run project. Cannot start debugging. The assembly to be debugged was built with a platform incompatible with the current system." I went back into My Project > Debug and it's been set back to Active (Itanium). I tried everything and looked around Google, has no-one else had the same problem? How do I fix it?

Where did it go? And most important how do I get it back?
When i try to save my program an error pops up telling me that it cannot debug because some sort of file is missing... While my other projects just work, and while i repeat the same steps (placing an entity like a button, coding it), it just shows that error. Its really strange!

View 9 RepliesI have an app I'm developing using vb/vs2010. It's an x86 app running on a 64 bit machine. It hangs when I run it in the debugger or the debug exe. When I run the Release exe, it runs fine. System memory doesn't seem to be a problem. I show 1.8 gig free after I load the Release version. I show a similar number when the debug is hanging. Just to make it all really mystifying, the debug version works if I step through it a line at a time.
