Awesome, thanks for the link Dave. I definitely need to learn more about the MF. Been living in the Web and Windows world too long.

not sure what I"m doing wrong, I downloaded  and opened the soution in location

 

NeonMika.WebserverExecuteableNeonMikaWebserver

 

it builds but is using the 4.1 framework not 4.2, if I update the projects in the soution to be 4.2 I'm getting alot of build errors. where is the "WebServer" solution you are referencing?

when I download the zip from http://neonmikawebserver.codeplex.com/

 

I get a zip with folders called "executable", and "framework" among others.

 

The project in builds but is referencing 4.1 not the 4.2 MF.

Hello,

 

I apologize if this is a newb question.

 

Is it possible to have a Netduino execute an "AutoPlay" (similiar to having an auto.inf on a cd or usb stick) feature when connected to a PC?

 

I'm ultimately wanting to launch an HTML file hosted on the SD card or even launch a windows application hosted on the SD card so the user can make changes to the predefined settings xml file on the SD card. is this possible? I would prefer to have it hosted on the SD card for the Netduino so the user doesn't have to install anything on their PC.

 

Am I asking for too much here?

If you run the ND+2 version (From the NeonMika thread post #91) it works right out of the box.  I actually did an install tonight to work on a new project.  Took the WebServer solution, built and deployed it (after having changed the IP address and other network settings in the program.cs file). After typing the IP in my browser the command webpage came right up showing all the commands you can run.

 

Hi Dave, Sorry to ping you again. I guess i'm the only person in the world that thinks the NeonMika webserver is not easy to get up and running. It looks like its running but when I try to go to the IP in the debug window, I get "connection reset" or "taking too long to respond". I have attached a screen shot of what I'm seeing. I get the NeonMika webserver sending response back. I have looked at the code plex site and it looks like the little code examples that were there are gone now. I remember seeing examples before. Anyways, I have found the most basic of webserver examples and can get the ND to send back content responses to the browser. Any ideas?

 

 

 

Nevermind, I HAVE NO CLUE what I did wrong in my application but ended up getting the line below to work. I created a new project and add the WebServer reference and that one line of code and it started working.

 

What I'm really confused about is I had to abandon my first project because it started saying "hardware error: check your device", this error came up after adding and removing references several times and I couldn't resolve so I started another project and its working.

 

 Server WebServer = new Server(PinManagement.OnboardLED, 80, true);

If I have DHCP disabled it looks like it launches but didn't respond. If I have DHCP enabled I get the message below.

 

Webserver is running on 0.0.0.0 /// DHCP: True

do you have the link to post 91? I can't seem to find it...

I'm really pulling the newb questions today, but what are the LE and BE folders in the BIN folder with the DLL's? I had to copy those along with my DLL's for the Webserver references. I have tried to Google but no luck...

Okay cool, thanks for the indept responses. I really appreciate it. I will let you know what I end up doing to accomplish my goal.

You are looking at the Netduino as a remote storage device and this is not what the Netduino is.  When the Netduino is powered, the application stored on the Netduino is running.  If the app is written to run in loop mode it continues to execute without end.  If there is no loop the application will run when powered up and run to it's end.

 

You can run something like the NeonMika web server on the Netduino which will host a webpage that a user can access via the Netduino's IP or NetBios name.  This web application can then allow a user to make changes on the webpage and submit the pages which use jquery and .NET to receive and store the settings and update the settings.xml file.

 

I am not sure what exactly you are looking to accomplish, but this sounds like the solution you may be looking for.

 

Dave, Question, I'm running the latest firmware on my ND Plus 2, The Mika webserver doesn't seem to work out of the box for me, lots of build errors. Do you know of any examples or references that have actual working examples for the Mika webserver?

Hi Dave, thanks for the quick response.

 

 I think you described what i'm hoping to accomplish perfectly. I have a few more questions:

 

1) would this solution require that the user is connected to a network?

2)  Is there a way to auto launch (like in a console or windows app I would just use Process.Start()) the webpage that the NeonMika web server would host? I'm trying to minimize the steps required by a user such as having them find the IP for the Netduino and browse to it in a browser manually.

 

My backup plan would be to build a WPF windows app and equip my module with a FTDI Basic Breakout - 3.3V and use serial communction to update the XML file. I'm trying to do this to give the best user experience.  

Okay, thanks Dave. I appreciate it

Great thanks, hopefully I can get something put together!

hey guys, I'm curious. Is this still the best option to play back audio files on a Netduino plus 2? I was hoping to be able to play wav or MP3 files from the SD card already on the duino. Ultimately, I want to output audio to an audio jack and put that into an input on other device. Is that possible without another component ?

do you have any code of how to utilize your lib? The links solution is just the lib not example project.

Does the http response class you are using implement Idisposable? If so, wrap it with using. Just another thought

By implement Idisposable I mean can you wrap it with a using statement like you do with the filestream object? Did you try to use a simple string array with only the size that you need rather than using array list? I think this should reduce memory used. Because array list is built on a basic array and a basic array only has memory allocated for the size it needs to be rather than having to grow dynamically with each add.

I know Get requests are typically lighter than Postbut have you tried to use Post to populate your database? I don't know how large your files are but it might be worth a shot. If the files are large then you could create smaller files. This would reduce the HTTP activity anyway with fewer and larger requests.

No problem, let me look at this code tonight, and give it more thought, Throughout the day I like a good challenge. Wow that's crazy removing the try catch increased the request size! Never heard anything like that. I know that throwing exceptions can be expensive but not having a try catch in the code that doesn't throw errors.. Confusing I'll get back to you.

Hmm, let me think about this. I'll try to make a sample app to reproduce, see if I can optimize anything for you.

Can you post an update of your source? I'm wondering if something else could be rearranged. Also have you written a console application that performs the same action as your Netduino application code? I'm wondering if your server that handles the http request might be the bottle neck. It probably isn't but it's worth ruling that out while you are testing for performance. I would time these requests and response times.

Maybe you could try to just have the Netduino copy the files to a network share and then have a scheduled console application that reads the files and executes the http requests.

http://www.dotnetper...om/array-memory

We might be splitting hairs but check this article out. You might see a bump in performance by using a standard string array so that memory doesn't have to be allocated and indexes have their positions changed when items are added.

Just init your string array to be the count of lines in your file. Then populate, see what memory looks like
