C# - Adding A Global Namespace To .net Webbrowser Control
Mar 2, 2010
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 am working on a solution that does not name namespaces in code files. Instead it uses the root name space of the project (which is the same across all assemblies). Basically there is only one implicit namespace.
Well, I am trying to isolate some code so that I can run FxCop against it. I explicated named the code file with a namespace to do this. This works for FxCop, but it bricks the entire solution.Visual Studio is now asking me to prefix all uses of the implicit namespace with Global. So instead of:
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:
[Code]...
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?
Which is the best way to store global variables, in My.Settings or My.Namespace. The reason I ask is because I need to know certain boolean values if certain forms are open from other forms. At present I am defining Global Boolean variables in My.Application, which give the result I require.
I cannot find a way to get LINQ to spit out xml the way they want. Question is, can LINQ do it or do I need to resort to hardcoding the xml the old way before LINQ to XML?
I have a solution that contains many projects all using the same root namespace. No code files explicitly name a namespace. So lets say the root namespace is ExampleRootNamespace.Now a problem comes into play when I want to add an explicitly named namespace to one of the code files I am working on. I want to be able to isolate this code from the rest of the assembly to be able to run FxCop against it. So I add something like Namespace Interfaces.CSV to the code file.
This causes any code that references this assembly to need to say Imports ExampleRootNamespace.Interfaces.CSV. So far so good. I can even run FxCop against the assembly. The problem now is that in other assemblies I cannot say any longer things like:
Public class frmInputBoolean Inherits ExampleRootNameSpace.frmFormTemplate
Visual Studio is now asking me to rename the namespace to:
Public class frmInputBoolean Inherits Global.ExampleRootNameSpace.frmFormTemplate
There are hundreds of errors related to this. So my questions are:
1) Why would basically naming a namespace under the root for the first time cause issues with the program?
2) Are there any workarounds to this issue without renaming?
I also want to add that with regards to ExampleRootNamespace.Interfaces.CSV I am not referencing this anywhere in the codebase. I'm currently just referencing it from a unit test project. So I don't see why adding this namespace causes an issue.
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?
I'm writing a piece of software that accepts XML from our clients. The xml has2 parts, a standard part that contains set fields, and a freeform part that allows our clients to add own their own xml
I can add dll file in global assembly through making a complete setup but know i want to add dll in to global assembly through code dose any one knows how it can be done.
I use Excel PIA thru "Imports Excel = Microsoft.Office.Interop.Excel". IDE allows to set "global" reference for any namespace (in Project -> 'Project name' Properties -> References). But it doesn't allow to set alias for this namespace, so I have to write "Imports Excel = ..." thru all files where I need it. This would be great to have such thing in IDE!
The XML would look like this <soap:Header> <aaa:TocHeader aaa:role="ADMIN" aaa:locale="en-US" aaa:softwareName="TOC" aaa:softwareId="aaaaaaaaaaa" xsdVersion="1.0" xmlns:aaa="http://toc.schemas.testing.com/headers/2006-02-01"> <aaa:Message>
I've been having fun with the xmldocument class recently but am struggling with namespaces. I've been trying (with some success) to merge parts of one XML file into another. The problem has been that one of them utilises a namespace on one of the interior nodes and therefore my xpath queries where failing when I tried to create a nodelist. This I fixed (after reading some great examples here) by adding a namespace manager and changing my query accordingly.
Everything looked fine initially and I appeared to end up with the desired effect, but the XML file that was created was failing in the target application. What I didn't realise at first (due to the length of the xml node values being wider than my screen!!) was that when I imported the nodes from one file to another, a blank names space was being added to the end of each node (xmlns="")
' load the xml template from the project resources Dim fdf As New XmlDocument fdf.LoadXml(My.Resources.fdf_template)
I'm attempting to create a bound WPF control; when I add a local namespace to the UserControl, I get strange output from the compiler. The header of the UserControl follows, with the offending line highlighted.[code]When that line is present, the compiler generates the following in the output:[code]
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 have a piece of code that i want many ListViews to run throughout the app at ItemUpdated. I'm sure the same can apply to many other control-events.How can I hook up a certain listviews ItemUpdated event to a sub in a class module?
here's my class module Public Class ControlParts
Public Shared Sub LSVItemUpdated(ByVal sender As Object, ByVal e As ListViewUpdatedEventArgs) Dim lsv As ListView = CType(sender, ListView) lsv.EditIndex = -1 End Sub End Class
Now if i add OnItemUpdated="LSVItemUpdated" to my ListView's declaration I get an error that 'LSVItemUpdated' is not a member of 'ASP.admin_order_aspx'. Well, I don't want this on the page. I wan't this to be globaly accessible. I could in the code behind call the LSVItemUpdated, but that will beat the whole point off.
I 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.
I am writing a few web based apps which will require a webbrowser extension. I have already used the IE webbrowser control that uses the trident web rendering engine. I believe this is MSHTML.DLL? Anyway, some of the users of my programs have complained of a few things. Particularily,
1. It seems to be a slow browser, at least compared to other rendering engines out there (webkit and gecko are 2 known ones).
2. On the developer side, it seems to be low in features. The features are sufficient in most cases, but there are some "special" things that I need.
3. It has VERY low HTML (and especially HTML5) compliance.
My question is, how much work would it take to use a different engine (such as webkit .net, which I HAVE heard of) and be able to distribute it easily. Or, if you guys feel ambitious, we could try writing a brand new engine ourselves. I know how big of a job it is, and frankly, I have no clue where to begin. I would just like your thoughts and opinions on the matter.
i have created an app to load an access database into a datagridview, which contains web urls. When button is clicked it webbrowser1 navigates to each url and each webpages document.inertext is put into textbox. This all work fine but after a while the webbrowser navigation becomes increasingly slower.

evrytime i add new controls to a form in vb.net the designer regenerates code and asks me to make corrections, so i have to keep on changing the object declarations to global using the 'global' keyword evertime it regenarates code,especialy dataset objects.how can i prevent this?
Ive tried to edit option on the webbrowser control, example javascript enable/disable. but found out that it uses IE's option and cannot be changed.So my question is: Is there a way to do a "webbrowser" without using the WEbbrowser control that is based on internetexplorer? If it is, can i change option example flash and so on?
i could use Global x as string in vb6 in a module to declare it with global privelages, how can i do this in vb2008? how to declare a global variable in vb2008? so that i could use it anywhere i want. i know global variables are not recommended in programming but i need one.
I have been working on an activeX control which works on serial port communication. Now I have completed the project and created its setup.exe using Visual studio 6 -> Tools -> Package and Deployment Wizard. Then I installed the control in another PC and in a new project included the control using project -> components. But when I click on the control in the toolbox and then include on the form it gives the following error : delete current link ? and on clicking OK, nothing happens. I tried searching a lot on google but didnt find anything. Another problem is that I have created a string array as a global array which can be accessed by all the methods.I am able to include the same activex control in my own pc when I have created the project. Here it works fine, I am able to access all the methods that I coded in the control, but the String array mentioned above can be accessed in other project. I tried writing Public before the array declaration but it give me the compile error : "Constants. fixed length strings, arrays, user defined types and Declare statements not allowed as Public members of object module."

This 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?)?
