I'm trying to add Windows Media Player to a simple vb 2008 express addition program.When ever I add the WMP my built fails with the following error:
'AxWindowsMediaPlayer' is ambiguous in the namespace 'AxWMPLib'.
I'm getting a ton of errors like this when attempting to build an empty VB.NET project: 'GenerateCodeAttribute' is ambiguous in the namespace 'System.CodeDom.Compiler' Is this some problem with my .NET installation?
View 1 RepliesI get the idea of using namespaces to organise classes and code.What I am struggling with is how to use them when developing custom controls and components.using a seemingly arbitary root namepace for a set of related classes.
Namespace MikeCon
Public Class MCButton
Inherits Button[code].....
And is there a 'right' way, or at least a 'better' way of setting up the namespace, i.e how best to use the Project Properties Root namespace and the Namespace statement in code files to get the outcome you want when developing custom controls and components?
I have a problem in VS2010 with a user control i have created, I wonder if this is a known problem and if there is a resolution.
My project has a root namespace of DEV2.MyApp.I have created a user control and dragged it onto my form at design time.In the designer i get an error for that form that goes like this:-
Type DEV2.MyApp.myCtrl is not defined Me.myCtrl = New DEV2.MyApp.myCtrl ()I correct it by removing the namespace DEV2. like follows.Me.myCtrl = New MyApp.myCtrl ()
However, everytime i make an amendment to this form on the designer, the error creeps back. Its really annoying and I dont really want to resort to having to create the control at run time to get around it.
Scenario:A widget developer codes using HTML and javascript.my vb.net application allows developers to create widgets for other users.in javascript you can call window.external to comunicate with the host windows scripting object and I would like to add a helper namespace with many functions to aid the development of widgets similar to windows sidebar's System namespace.
Problem:So I could allow developers to use Window.External.System but how can I just allow them to access System directly without using Window.External?Microsoft adds a System Namespace to windows sidebar gadgets host window which is just an internet explorer server window.
I'm an amateur programmer who's learned quite a bit from online references, and usually searching eventually reveals the problem but I'm stuck!I've overcome many obstacles when creating a custom button on the Ajax Editor control, namespace issues, registring the controls properly etc. I resist the temptation to ask for help because the errors should lead me in the right direction. Now I get no errors, but the control isn't visible! The tag is in the .ASP page and I even set the width, height and visible tags in case it's being hidden but nothing shows up.

I need to read an xml document from a database record into an XDocument object in order for it to be deserialized. So that the deserialization will work, I need to apply a specific namespace to each of the level 1 elements. So XML looks a bit like this:

How do I prevent the blank/empty namespace being added to each child element of the element to which the required namespace has been applied?

View 2 RepliesThis class is located in the namespace Acme.Infrastructure.Interface.A class with the same name EventArgs exists in the System namespace.In another project in my solution I have a class Acme.BusinessModules.MyModule.MyClass.When attempting to use the EventArgs class I have to fully qualify the class name or the compiler thinks I am using the System.EventArgs class.My understanding of namespace resolution was that the compiler would first look for the class in the current namespace, and then its parents. It seems that the compiler checks in System before it checks in sibling namespaces. Is it correct that System is checked before the sibling? Or is this behaviour caused by other issues (Imports order?)?

I have a .net application that uses customerrors web.config module to display meaningful messages for errors. It works without any issues for 500 errors/exceptions caused by non-ajax and ajax components (updatepanel). However, in a scenario where updatepanel's asynchronous request times out, there is no error raised at all. I was able to see the timeout in firebug and come up with a solution that would at least display the error message as an alert and then redirect the user to the 500 error page using javascript but it's not quite doing what the rest of the application does in case of an unhandled errors like these. I basically just want everything to go through "LogEvent" mechanism so based on the severity of the error, it does the necessary work.This 500 error page doesn't have anything in the Server.GetLastError() for these timeout scenarios. Is this an expected behaviour? Can it be changed so I do have access to these timeouts in Server.GetLastError() OR maybe just run this error through "LogEvent" mechanism? Is there a better/more graceful way to handle this issue?
Below is my code to give you an idea, not exactly what I have in my application but pretty close.
Web.Config
<customErrors mode="On" defaultRedirect="~/Errors/ErrorUnknown.aspx" redirectMode="ResponseRewrite">
<error statusCode="500" redirect="~/Errors/Error500.aspx" />
</customErrors>

So when i build or click debug on my program. No errors come up and its smooth. So i decide to publish my programme. However. I come up with a bunch of errors during the publishing.
Here they are:Error 1 Cannot publish because a project failed to build. 1 1 Simple CALC
Error 2 Unable to copy file "binReleaseSimple CALC.exe.manifest" to "binReleaseapp.publishApplication FilesSimple CALC_1_0_0_0Simple CALC.exe.manifest".

As I say, I've got an application which I'll refer to as "AppName" (note the upper case 'A' and 'N') which, for example, attempts to reference "My.Application.Info.ProductName". Adding a breakpoint and putting a QuickWatch on that call shows the error:

I've been developing a Vb.Net app lately, and I'm trying to make it as lightweight as possible (ie make the binaries as small as possible).I've done all the trivial stuff, but while browsing the binary with ILDasm, I noticed that it has a My namespace, with a lot of methods, although I don't use any of these in my program. It seems that there are default Get/Set methods for every form, and other methods.Or, can you show me a use case for the methods bundled by default in the binary? PS: I guess it's not going to make a huge difference in binary size: I'm just asking this out of curiosity; why would the compiler bundle useless methods in every binaries? Perhaps I'll learn that these methods are actually used somewhere under the hood.
PPS: Here's a minimal example:
Module Test
Sub Main()
End Sub
End Module
Using VB.net, I have a namespace which I'd like to rename for the future. However, I'd also like to keep the old obsolete namespace for a time to ensure backward-compatibility for our consumers for awhile. Is there a way in .NET to have two namespaces, one ordinary and one that merely is an alternative name for the other?

I'm trying to add the Compatibility.VB6 namespace in some of my VB.NET Programs (using 1.1 framework, 2003). It was added in one of my programs because of a migration wizard but i can only use these commands in that particular program. How would I add that to the others?
View 4 RepliesI am trying to work out an example from ".NET Domain Driven Design with C#", which contains a code example where you can see declared some attributes of type DelegateCommand. Now, I've tried googling it up, but I can't find its reference anywhere on MSDN (actually, I found this article, but not DelegateCommand's article itself). Is the DelegateCommand something that's part of WPF or is it just something created in the book?

View 1 RepliesI'm currently maintaining some old code for a company. As it would happen, the current app I'm modifying uses an older version of the in-house library (we'll call this Lib1.dll). They also have a new version of the library called Lib2.dll that improves upon the previous library in many ways.
Unfortunately, Lib2 is not backward compatible with Lib1. What's worse is that they both use the same namespace Product.Common.
How do I use Lib2 and Lib1 in the same project? Right now if I add references to both of them, VS tells me that certain classes are ambiguous (which makes sense, since they using the same namespace).
Basically, I need something like:
Imports Lib1:Product.Common.Class
I'm using VB.NET 1.1.
What should go into the top level namespace? For example, if I have MyAPI.WebLogic,MyAPI.Compression, etc. If I put classes into the top level namespace, am I violating the principle of encapsulation?
View 5 RepliesI've googled for creation of namespaces and found some very useful examples, what these examples didn't have is how do I compile and implement my created namespace on my system so I can include it from my various applications.So for example, if I create a namespace to load a config file from my application path and insert it to an array, Do i need to include the namespace on any project I use or is there a way to make it part of my environment?
