I am fresher in vb.net but I want to develop a project in this case I want to use the system.Configuration namespace's specific calsses. But I am not clear which class i use and why it's function and it's use.
Receive 'ConfigurationManager' is not a member of 'Configuration' in VS2008.I read all of the topics in the forum about this error Tried adding areference to System.Configuration.dll to the project and an "Imports System.Configuration" to the vb file.Still get an error
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?)?
Is there any limit on number of classes that a namespace can have in .net ? Further what is the recommended number of classes that there should be in a namespace?
iam creating Vb.net classes under the different namespaces after that build that source code,i got the Type Library file.but iam using the Assembly Name in VB6.0 iam not able to getting classes under the namespace wise.
eg: Dim A As New Test.A - It was possible
but iam using with one namespace like
Dim A As New Test.Utility.A
This was not working.
Dim obj As DynamicPDF.ReportDocumentLayout - it was comes correctly But, Dim obj As DynamicPDF..ReportWriter.ReportDocumentLayout - Not comes like this.
Is it possible to have multiple classes in a namespace and be able to reference the functions within the clases if the Major class is instaniatated from another class?? for instacnce:
Namespace Database Public Class Data Public Class Prepare
When you develop a class library that will be used by others, are there any guidelines on how you decide what namespace to put it under? I often find third party classes just use the company name as the root namespace but I was also wondering if it is frowned upon (or even possible) to add one of your own classes to an existing framework namespace.
I have a large web app in vb.net 4.0. Its default namespace is configured in its project properties. None of the root-level classes in our app are surrounded by namespace declarations. When I add a .asmx file to the root folder of the website, it compiles fine, but it doesn't work for some reason (already asked why in other topics). So to get it to work, I try to surround the class declared in the .asmx by a namespace declaration. As soon as I do this, I go from zero compiler errors to about a zillion. My app can't find ANYTHING in the root namespace. But I haven't changed any other files, only this .asmx file.
WHY is it behaving this way? How do I prevent it from behaving this way without refactoring the entire app? I would love to blank out the default namespace and add them explicitly around every root-level class, but I'm not sure that would fly with our release manager, and I don't even know if it would fix the problem.
I would use the System.Linq.Dynamic. I added the specified Dynamic.vb file, that starts like this:
[Code]...
to my (VB.NET)solution. Now Visual Studio does not recognize anymore in the project files the System.XXX references, proposing me to change them to Global.System.XXX
I want to know what are classes , objects , a namespace , subroutines,functions,methods,properties and differemce betweem byval and byref in your words.
When we are typing the msconfig in Start>Run the window is appearing that is named System Configuration Utility . Now I want with WMI and API objects access this data and change them by programming in VB6. Specially, I want to change data on Start-up lists and Boot up services Can any one suggest me a solution?
Note: When I am going to use registry datas in compare of System Configuration Utility I have found that all of applications are not listed in registry + startup folder of windows. I think there is a provider for this issue in windows that returns or manages all applications on startup. I am searching for that.
When i try to run my app I get this exception "Configuration system failed to initialize"I recently added a datascource to the app and am assuming that something has gone wrong there but it was all working ok and then this error just started.I assume it's a problem with my appconfig file which i'll post here I cant see anything wrong with it but.!!I've tried deleting the ConnectionString Section but nothing helps and i cant run my app at
I have an .NET winforms application(A). I am calling another .NET exe(B) file from the winforms application. When executes, it throws the following error.
I haven't kept any configuration file for the second exe file(B).
I am using Visual Studio 2010 and referencing System.Configuration at the top "Imports System.Configuration" but I'm still getting not declared and could be inaccessible due to it's protection level. What now?
Have you tried configuring ASP.Net Membership together with Enterprise Library DAAB? When I run my application it throws the following exception: "Configuration system failed to initialize" It seems that it encounters a problem that normally don't occur when I setup my configuration file.
I have a VS Solution with several projects. I want to set a specific project to the start project in Debug mode. Everything seems to run fine as I set breakpoints on the initial Form and several initialization procedures. At one point however, I get this error which is not an issue when I compile and run the release version.
Here is an illustration of the Exception. Unrecognized configuration section configuration. (C:...path...File.vshost.exe.config line 25) The config file is listed below an the jit debugging = true statement is on line 25
I am trying to execute a VB .net console application called Application1 that I created using Visual Studio 2008 with .net framework 3.5. When I run it under the windows scheduler or from a command prompt it works fine. When I try to run it under a purchased job scheduler, I get a message stating that directory APPLIC~1.config is missing. What properties does system.configuration use when it tries to find an application's .config file? Can these be set when my application starts?
Note: I was able to use ConfigurationManager.OpenExeConfiguration(My.Application.Info.DirectoryPath & "" & My.Application.Info.AssemblyName & ".exe") to get around this issue but would like a cleaner solution. I do not want to do this each time I want to retrieve an appSetting entry.
I am trying to upgrade a VB 2003 program to VB 2005.One warning I am getting is:
'Public Shared ReadOnly Property AppSettings() As System.Collections.Specialized.NameValueCollection' is obsolete: 'This method is obsolete, it has been replaced by
I am the author of a freeware that have been hundreds of downloads without problems... and only ONE user reports to me the error in object.Since the exception is handled, tanks to his report I can realize that the error is generated when is read this code line:
If My.Settings.Opened = True then
Now the question is: why a single PC over hundreds have problems gaining access to My.Settings?His PC has installed XP Home Edition SP3, my program is compliled for Framework2.0.
I got some set of base classes within one namespace and few sets of derived classes in other namespaces. Everything in one project.[code]...
OK, it can be done declaring .SubElements as Protected in BaseElement class. But in this case I cannot access this property from other classes in Base namespace that are not derived from it.
I tried adding Friend keyword, but it made this property visible when I'm instantiating derived classes too.
So... any way to hide some properties when using derived classes while being able to use them using base class?
i am using databse connection model but can't get actual result because of this error , i don't know why this occurring ,i have use the windows application with app.config file, i paste xml code.
