View 4 RepliesAjax - ASP.NET MVC Structure And Use The Actions And Controllers?
Oct 5, 2011I am developing an application in ASP.NET MVC structure.I was wondering, I am trying to create a site that only has one page, it has a navigation bar on the left (Which is a list of user input), and then the main content in the middle.My question is, can I make the navigation bar (The user input list) static, and make the main content change, based on the user input, with an asynchronous AJAX postback? I would have multiple controllers which would set different results to the main content, based on the user input. How would I go around doing so, partial views and calling actions with asyncpostback's?
View 1 RepliesVB Be Supported In The Micro Framework?
Jan 5, 2009When will VB be supported in the Micro Framework? it seames as there is a lot of new technology comeing out of MS lately leaving VB behind, insted of in step with C# like origionaly promised.I know that the VB compatibility dll has yet to be ported, but if this is the only hang-up, skip it for now and get some eary adopters playing with it.most of us can read C# so VB documentation is not hugely needed, just a few quick samples in the SDK.Please help, the company I work for could have soo many applications for this tech, but we are commited to VB for it's ease of use and it's natural synthax for reading.
View 2 RepliesPS2 Buzz Controllers - Display A Picture Of The Buzzer When Key Is Pressed
May 27, 2009I have decided to make a set of old PS2 Buzzers useful. I have been working on a VB.Net project in visual studio that will display a picture of the buzzer and when the actual key of the buzzer is pressed it will light up on the picture. I have added the USBHIDDRIVER into my project but have no clue on how to get this going.
The buzzers have 5 buttons, on the top is one big red one that has a light. There are four buzzers which are linked into a hub and streamed to one usb cable. When plugged into the computer they are recognized as a HID compliant device.
I have worked out the codes to make the lamps light up and have found the code for every key from Simple Hid Write. To make the lamps come on the code is WR 00 00 01 01 01 01 00 00 That turns on all the lamps. I would just like to know how i could make the happen. I have a checkbox that when ticked i would like it to send that code the the Buzz controller!
Micro Seconds Stop Watch
Jan 22, 2011I have build using the computer Performance counter a Stop Watch class with a precision of 1 Microseconds ( 1/1000 of a milliseconds )It works good but While building this class I had a problem And found a work around to it. But I am not please with this work around.As you may know, the CLR does not create it's object at the time where you declare them, but when they are first needed. So, while building a class that a timer with such precision, the elapsed time, you will get include the time used by the CLR to build the class. This is a problem since it takes 700 to 800 microSecond to do so.I have try using a code like the one I post here, try using start/stop method, try builing the class as native code API etc. And always the same problem,I get some CLR time include in the elapsed time.The work around I finaly found is to use the fact that the CLS will recycle an object if you dispose of an object and recreate immediately after.
So, what I do, is create the timer, dummy use it, dispose of it and recreate it to actualy do work with it. Here again, I get a small CLR work time of 3 to 4 Microseconds for recycling work.I have no hope to find a better solution using a managed code class, but I am sure that there is a way to put in memory from managed code, an unmanaged class that will be ready to be use by the managed code.If you try to run it, the first time you will click the button, you will get an extra 3-4 microseconds on the result.[code]

View 1 RepliesConnect Micro Controller To Internet Via VB Application?
May 29, 2012i m currently working on application that has to monitor temperature and humidity of a particular place and constantly report the same to the user over internet. So far, I m using LPC1768 and its ethernet module collect the data, process it and send it to the router. On the other side, i have a computer which is connected to the same router and running a VB application where the data is mined and reported in a excel.
This setup works just fine. Now, i want to monitor the same data over internet. How can i do the same?
Here i was able to connect to the micro-controller using the IP 192.168.1.100 port 80. I m aware that the IP is a local one and to access the micro controller from Internet there is another way.I have a IP based webcam which enables us to monitor from internet. How should i make micro-controller data be accessible from internet.(similar to IP Camera).
LDAP Authentication - Cycle Through The Local Domain Controllers Listed On The Machine?
Jul 6, 2010Our company is developing software projects that use a users windows username/password for program authentication. Our programs encrypt the username /password, send them to a web service. The web service decrypts the username/password and authenticates the user against our LDAP using the System.DirectoryServices namespace. This works well. There are two methods, one that validates the user and passes back the user's LDAP info in a datatable, the other passes back a boolean that indicates the user is on the domain. This is working just fine. Over the 4th of July weekend, our domain server hung. While it slowed down the login process for windows while it re-routed to a secondary domain server across the country, all our programs could not validate the users because our local domain controller was down.So I have been asked to update the web services to include a list of domain controllers that can be used if the local one is not available. Below is a snippet of code I use to validate a user:
[code]...
The getinfo function uses the directory services to create an LDAP entry, then do a search based on the account name (windows username) and populates properties for common LDAP information. How can I extend this function, or re-write it, to run down a list of domain controllers found on the network to validate a username? I was thinking of putting the domain in a database, but that requires administration as they change. Is there a way to cycle through the local domain controllers listed on the machine?
Using Serial Ports - Take The Communication From The Software And Redistribute It To THREE Eurotherm 3216 Controllers?
Sep 7, 2009I'm reasonably proficient with VB but never had any expirence with communicating with hardware. I have a piece of software that communicates with a Eurotherm 3216 process controller via RS232, but its use is fairly restricted what it can do.What I want to be able to do is take the communication from the software and redistribute it to THREE Eurotherm 3216 controllers, so my software would intercept the comms and effectively emulate the Eurotherm.
