Asp.net - Concept Needed For Building Consistent Urls (routes)?
Nov 24, 2010
My project has the need to build consistent urls similar to the ones here on stackoverflow. I know how I "can" do it by running the string through multiple filters, but I'm wondering if I can do it all with a single method.Basically I want to remove all special characters, and replace them with dashes BUT if there are multiple dashes in a row, I need them to be a single dash. How can I implement this as clean as possible?

I'm trying to set up Route mapping tests using MVC Contrib as described in Test ASP.NET MVC routes using MVC Contrib .The tests compile and execute, but they always fail with the message "The URL did not match any route."I set up another test to try to get an idea of what the problem is:
Public Sub TestIndexRoute()
Dim routes = New RouteCollection
myMvcApp.MvcApplication.RegisterRoutes(routes)[code].....
That test fails on Assert.NotNull(routeData, "routeData is Nothing."), so I know that there must be some problem with the MVCContrib code that is trying to access my app's RouteCollection.From the blog post:It also assumes you set your routes in the ASP.NET MVC RouteCollection object.How do I confirm that I'm doing that? I'm using routes.MapRoute within MvcApplication.RegisterRoutes method in the Global.asax code behind. Is there something else to do to set this up properly?

I have the following controller actions:
<HttpGet()>
Function News() As ActionResult
End Function
<HttpGet()>
Function News(ByVal id As Integer) As ActionResult
End Function
I want it to be smart, and go to the first if I have no ID in the url, and the second if there is. I got the following error:
The current request for action 'News' on controller type 'MarketsController' is ambiguous >between the following action methods:
System.Web.Mvc.ActionResult News() on type TradeChaseMVC.MarketsController
System.Web.Mvc.ActionResult News(Int32) on type TradeChaseMVC.MarketsController
So, I thought if i explicitly created routes without the id parameter optional, like this:
routes.MapRoute( _
"Default2", _
"{controller}/{action}/{id}",
New With {.controller = "Home", .action = "Index"},
New With {.action = "^[a-zA-Z_]+$", .id = "d{1,8}|"}
[Code] .....
It would work, but it doesn't same error. Now I know the simple solution is to call my methods different things, but i don't want to do this. I was also thinking of creating an attribute to prefix the ID method, to check for ID being there, and if it isn't dont allow that method, but I can't get this to work either.

I'm creating an API for a website. I'm using ASP.Net MVC 3 and I'm trying to create routes that support an optional .format parameter. So the client app could request /user/post.json, /user/posts.xml or just /users/posts I was able to make the .json or .xml ending url's work using the following route:
routes.MapRoute( _
"no_params", _
[code]....
But I couldn't make the url without the .format parameter (/user/posts) work alongside.

"Multiple types were found that match the controller named 'reviews'. This can happen if the route that services this request ('{controller}/{action}/{id}') does not specify namespaces to search for a controller that matches the request. If this is the case, register this route by calling an overload of the 'MapRoute' method that takes a 'namespaces' parameter."
I've recently added a new "Admin" area to my app and within that I have a "ReviewController". There is also a "ReviewController" within the main app folder:
ah - as a new user I can't post an image, but basically I have a "ReviewController" in "Controllers" and in "Areas/Admin/Contollers".
I have 2 routes set up so far:
Default route in Global.asax.vb
Shared Sub RegisterRoutes(ByVal routes As RouteCollection)
routes.IgnoreRoute("{resource}.axd/{*pathInfo}")

I have two arraylists that contains links in one and the root url in the other. Sometimes the lists dont equal in number and I would like to iterate through the links list and if it contains a matching root url add it to a third list but also avoid any duplicates. I tried this but am not getting consistent results.

I have a class that gets 2 label controls passed to it byRef. So, while my class is being executed I want the labels on the form to be updated. This works Most of the time, but sometimes it seems the form stops updating till the class has finished its process...below is some of the code that I am using to do this...
Public Class clsImportWWDB
Implements IDisposable
Private strSearchTag As String = "" 'Last Tagname of value scanned
Private intMeldsFound As Int32 = 0 'Number of Alarm Messages Found
Private _MyForm As Windows.Forms.Form
Private _FileName As String

I'm having an issue with a program. It seems to run (continuously) any amount of time from a few days to about a week.Eventually, and seemingly randomly I get the following Errror. None of the users see a consistent item that is causing the hang, and sometimes it's even just running with no interaction with the user.I just get long signature alpha numerics as a debugging tool.Is there any way to
a) force my program to kick out of the hang if it detects one, (and I guess, how could I write a separate thread to detect a hang?)
b) find out where my program is hanging?
c) if none of these options are viable, some coding practices I might be doing wrong that I could change to help avoid this?

A commercial application we are selling can display a User control written in VB.Net in the interface. I am writing a vertical strip that will display some of our ads to our customers. I would like to be able to control the message and the ads. My idea is to upload an XML file to our server, then have the Vb.Net add-in (user control) download the XML file to a temp location and display the contents as advertisement. 1. Is that a good way to do this? I am open to other suggestions. 2. Is there a way I could embed javascript inside user control? I want to be able to animate the text displayed if possible and I dont know how to do that in Vb.Net user control.

I am replacing a VB6 application with a rewritten counterpart in VB.Net. In the VB6 app there was a 'control' application which presented a form to the user and allowed them to select a 'client' from a drop down list. Selecting a client caused the reading of an ini file which set client-specific parameters, including the program names of several dlls, which were also written in VB6 and registered on the subject machine.
For example, each 'client' had a different letter format, and the letter was written by the selected dll. This made everything late-bound, but there is only one user. Most of all, it made it convenient to continually update individual letters by updating only that dll, and dropping the dll on top of the old one. Thus the (clerical) user had only to be told to save this file to the usual folder. I could have compiled everything together in one exe, making my updates larger and more complex.
In re-doing this in VB.Net, how should I replace this sort of approach?
I could tie everything together in one big project (and compile it to an exe which is the large update I was avoiding). Should I just do that? If I continue with the approach of having my client-specific (.net) dlls compiled separately, does this make sense in the .Net world? How do I call them? Do they need to be registered as they were before? What's the right way to do this and still give me the flexibility I had?

I am having difficulties grasping the concept / context of two dimensional arrays. For the assignment I am working on I am required to use radio buttons to allow a user to vote if they like or dislike an item from a combo box. The contents of the combo box have been populated through the IDE via tht item property.I understand how to set up my rows and columns, which will be, (0 to 4), (0 to 1). The trouble I am having is how to record and display the votes and have them correspond to the selected item from the combo box. Can anyone give me an example of how something like this works?

My responsibility is to build a vb.net function that when a scanner scans an object, it would take the scanned string and call a stored procedure to get a row of data that match that scanned string and pass the data row to an application that would print out a label. below is my vb.net and sql server stored procedure script 1. Do I have to come up with a public class in order to store my row of data to pass it on to a different vb.net application that would take that data row and print out a label? 2. In my stored procedure, how would I return the founded data row to the vb.net function?

We have developed a vb.net application using multi-threaded listener concept and a dedicated thread for each folder to monitor. With that we simultaneously keep track of the incoming files in each folder.Currently, we are facing an issue whenever we receive multiple files of bulk volume, parallel processing of the files getting delayed with thread concept or failing sometimes.We need to implement the same logic with some other concept avoiding multi-hreading. Or is it possible to achieve performance tuning with the same thread concept?

I'm trying to understand the concept of Raise Events and threading, From this tutorial i've just read in the author example he wrote that you need to use an event when calling sub when using threading, but he didnt elaborate enough in this subject, why can't I just call the function/sub as i always do?

I am trying to convert an industrial simulation program to a VB program There is one hard concept that I have problem with, it is called "Duplicate" Ex: When 1 person pass the duplicate block A, then 2 persons comes out, (that person is cloned). 1st person goes path 1, has delay time of 1 hour. 2nd person goes path 2, has delay time of 2 hours. At the end of the 1st hour, 1st person arrives at the detour, at the end of 2nd hour, 2nd person arrives at the detour, but 1st person already moves on to the next task for an hour.
So you can consider them doing their separate tasks simultaneously. Then complication comes in when somewhere down the path, 1st and 2nd person pass another duplicate B, then total of 4 persons will run into their own separates paths and delays. Then they will come back to the starting duplicate block A, thus creates total of 8 persons and follow the same path above again.
Until some condition has been met (ex: total number of persons pass through duplicate B), then all of them will leave the system.Anyone has any idea what is the best way (logically easy to follow) to program the concept? I hope I explained it clearly. It's unfortunate that MSDN doesn't allow attaching image or video.

I have build a VB.Net windows application which does uploads data into database and basically updates two controls:
1. A textbox which is constantly updated with one line per database record upload.
2. A label which keeps track of the count of database record uploaded.
I have used BackgroundWorker thread concept, where the thread's bgwWorker_DoWork() method contains the business logic for upload and bgwWorker_ ProgressChanged() updates the 2 UI controls based on uploads.But the issue I am facing is that I do not get complete updates on both the UI controls. Sometimes the thread bypasses update of textbox and sometimes of label. I could resolve this issue by adding System.Threading.Thread.Sleep(25) before each UI control update code.[code]
