Buffer/Array - Safe Application That Contains 3 Threads - Data Acquisition And Decoding - Data Graphing - FFT And Filtering
Aug 26, 2009I am trying to write a thread safe application that contains 3 threads : -
1 - Data acquisition and decoding
2- Data graphing
3 - FFT and filtering
Thread 1 is collecting bytes from the serial port and converting them int integers (so taking two bytes) after is has captured 64 Bytes and converted into 32 integers, it then needs to pass the array to the graphing thread.
The graphing thread then plots the data and waits for more data.
Thread 3 also waits until thread one has collected 2023 integers and takes these and performs some FFT calculations (which take time).
My question is how do i share the arrays between the three threads without deadlocking the program? as the serial thread will be flying around reasonable fast (1000 bytes per second) so it will synclock onto the shared buffers for most of the time.
Originally i was going to use two synchronised queues, so when thread 1 has collected 32 bytes it queues the data into the graph queue, and once it has collected 2023 it queues the data into the FFT queue.
Then thread 2 and 3 can simple dequeue the data.
However using queues has the overhead of casting the data in and out, and as i know the data type i was planning on using two arrays :-
Dim GraphArray() as ushort
Dim FFTArray() as ushort
Then Thread 1 adds data to each thread, and thread 2 and 3 simple wait until the correct amount of data is available before removing the data. my question is there an array type that allows me to remove x amount of data from an array?
Because i cannot do this easily with the ararys defined as above (GraphArray, FFTArray), as i was planning on making them 1mByte and allowing thread 1 to fill them Knowing they should never overflow and then let thread 2 and 3 remove x amout of bytes at a time unless there is a better way of doing it
Remove All Trace Of A Component From Project?
Jul 15, 2011I have been making a order processing system for a friends company and have 99% completed it. i was going through everything double checking all the components and i put a "DotNetBar" component on the form but then deleted it as i didnt need it. i only have a trial version of the dotnetbar and do not plan on publishing the software with the component on.
so after i deleted the component from the form i built a test version of the system and installed it on a different computer but when installing an error appeared saying something along the lines of dotnetbar component cannot be found. i couldn't find any trace of the component in the page.designer.vb file.
im by far no expert in vb (this is the first real program i have developed for actual use), i cannot find any way of getting all traces of the component of the project.
DB/Reporting :: Debugging On Xp Machine Data-set Gets Filled / Debugging On Vista Box It Fails
May 1, 2009I'm having to write a reporting application that gets information from some Interbase servers and it also has to work on Vista as well as XP, I'm using to connect Borlands Data Provider.[code]My Issue is that debugging on my xp Machine the dataset gets filled, debugging on my vista box it fails ("Interbase provider initialization failed"), my initial thought was that this could be UAC related but I've compiled the application and 'ran as admin' and still same issue.

Asp.net - Debugging Dll In Web Application?
Sep 3, 2010I have a vb.net web application in visual web developer 2008 with a dll file and i need to debug a method in that dll. I also have project source files for the dll file itself. How could i make the web application use the source instead of the dll file so that i'd be able to debug it? I've tried debugging the dll project itself, but it's not a very good solution, because it seems the dll depends on the web application settings and data and it would simply be too much work to get it working.

View 2 Replies.net - Debugging ClickOnce Deployed Application
Nov 9, 2010I am new to ClickOnce deployment and at first glance it seems a great way to maintain .Net applications updated with ease. I am developing a simple application that stores information on a mdb database and over some XML files. I understood how to use the "data" folder with ClickOnce and I am developing the part of my application that should migrate the data from older versions after a ClickOnce update. Now I need to debug that part of my code that only runs when the application is in "networkDeployed" mode. So actually I'm doing the following really slow process to test a new deployed version:
publishing the application on a provisional website (I can choose between a faster locale iis site or a real online one) installing the application from the deploying website (the first time) or running the old installed application so it automatically catch new updates and gets updated... running the application
So basically I have two problems here:
the whole process is much too slow :/ I'm running the app as every other app directly from the OS, so I can't access to the debugger...
I am pretty sure that there are better way to test ClickOnce deployed applications...
Debugging Windows Service Application
Sep 1, 2011I have created and deployed a windows service application and I added this line of code "System.Diagnostics.Debugger.Launch()" in the beginning of OnStart method in order to be able to debug the service but when I start the service the nothing is happened. I think the OnStart method have never fired otherwise the visual studio will popup once the debugger.launch line is executed even I tried to write some text to the event viewer to make sure but nothing gets written to the events viewer after I started the service. I included also the debugging symbol in my windows service setup project but I end up with the same result.Why it's not working? How can I make sure that the OnStart method gets fired or not?

Debugging C# Silverlight Projects From Vb Web Application?
Nov 12, 2009I have a problem whereby I cannot debug a c# silverlight application project that is hosted from within a visual basic web application. I add breakpoints to the main App constructor and the symbols are loaded ok but my breakpoints are never hit. I have concluded that it is a vb/c# interop problem as to test i did the following.
Created a new c# web application project
Added a c# silverlight application
Added a new vb web application project
Added references to the silverlight project from both web apps
set a breakpoint in App.xaml.cs constructor
if i run the c# webapp the break points are hit whereas if i run the vb webapp they are not.

VS 2005 Debugging A Not Responding Application
May 7, 2009I can pause the application and see that it thinks no threads are running so no call stack. The other projects in the same solution are all responding fine, just this one stalls. I can not think of any way to work out what it was doing at time of stall, I have no event logs, no breakpoints, there is no particular thing I can check for in my own logging system (which is quite extensive) that shows where/why/what the application is hanging for. Any clues on how to solve/investigate? To add, this is on a Vista box, but not able to move the system to anything else (source controlled) until I can find out what this is. Its an avenue I can go down if required however.

Best Method Of Remotely Controlling/debugging A .NET Application?
Apr 25, 2011I'm running a VB.NET application 24 hours a day on a dedicated machine. I'd like to be able to receive status updates and also control/debug the application remotely (i.e. from another computer via the internet).It would be an advantage if the communication was lightweight (in terms of bytes sent and received) so I can control the thing without needing a fast internet connection. Also, I'm running the application from within the IDE at the moment because there are some unhandled exceptions and it's easier to debug this way. It would be nice if I didn't have to compile it and catch all the errors.What is the easiest way to set something like this up, and what do I need to be aware of in terms of security?
Update:To clarify what input I need to give the application - in theory, none. If all went to plan I'd just set the application off and reading some sort of log would be fine. The problem is that it is unstable (mainly because it calls a web service which is very unstable and returns all sorts of weird things) and therefore seems to need constant input on my part.
It was my thinking that the only way I could do this sort of debugging remotely is by catching every error I could, reading the log, and somehow instructing the application to behave properly in future.

Oct 2, 2010My new office project is based on an MVP design and is in VB.NET (.NET 3.5), using multiple libraries (like EntLib, internal corporate framework, etc.).

IDE :: Debugging - Declarations Fails To Initialize After Application.Restart
Apr 14, 2009In my code the application will restart using the Application.Restart statement from another form named frmDatabase.
The application seems to restart while debugging but yet the dataset, tables etc which is declared right below the class declaration for the startup form seems to fail initializing when the restart is done.
Compiling and running the application works like a charm and there is no error like this when running the executeable.
I also Inserted a breakpoint in the Form_Load event and the debugger seems to skip all the statements when the application is restarted all the way down to where the exception occurs.
Declarations:
Public Class frmMain
Public objConnection As New OleDbConnection(strConnectionString)
Public objDataSet As New DataSet
Public objCommand As New OleDbCommand
Public objDataAdapter As New OleDbDataAdapter(objCommand)
