Whenever I create a new folder in my website (VS008) and add an item (Class) it can't be seen by the other pages, even though new class is public. Only if I add the class to the app_code folder or create a bin folder for it then it could be shared from these folders however I want to create my own custom named folders for organization and keep my classes there.
View 2 RepliesI've inherited a VB.NET website and it won't compile because the class1 in the file class1.vb refers to class2 in a file called class2.vb. I get the following error when trying to compile: Type Class2 is not defined.
When I look in the object browser the classes are listed separately (i.e. not all grouped under the same namespace) and appear as:
Public Class Class
Inherits System.Object
Member of C:...mywebsite [code]....
I have some code in my new asp.net app that I need to share. So i created a shared class called
"utilities.vb" and put it in the APP_CODE folder. There is a function I have in there that pulls a person's image based off of their MemberId.
[Code]....
And I can call this function from my page using utilities.FcnGetMemberImage(). Ok, so all good so far until it complains about...
"Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class"
when referring to the Server.MapPath()
But the problem is that if I don't make it a Shared Function, I can't access it from my other pages. But if I do make it a Shared Function, it throws this error. The fix is supposed to be that I either don't share the function, or
"add the shared keyword to the member declaration", according to Microsoft at
http://msdn.microsoft.com/en-us/library/xfsswe45.aspx
But I'm not exactly sure how to "add the shared keyword to the member declaration" or what this means exactly and how this might affect other parts of my code?
Or is there a better way to work around this dilemma?
I'm building an online system to be used by school groups. Only one school can log into the system at any one time, and from that school you'll get about 13 users. They then proceed into a educational application in which they have to co-operate to complete tasks, and from a code point of view, sharing variables all over the place.
I was thinking, if I set up a static class with static properties that hold the variables that are required to be shared, this could save me having to store/access the variables in/from a database, as long as the static variables are all properly initialized when the application starts and cleaned up at the end. Of course I would also have to put locks on the get and set methods to make the variables thread safe.
Something in the back of my mind is telling me this might be a terrible way of going about things, but I'm not sure exactly why, so if people could give me their thoughts for or against using a static class in this situation,
I'm totally new to the Microsoft dev scene so please go easy :)Currently, I have a solution that contains two projects (ASP.net websites, FWIW). If I create a class in Project1, how do I expose it to Project2? Is it automatically available to Project2 because they are in the same solution? Or do I need to do something special to make the connection?

We have shared CSharp classes put into a shared folders for re-use. Now I want to add those classes into my project by creating a new folder:
1) Right click the solution,
Add -> New Folder
Give it a new, eg. SharedClasses
2) Right click the new folder "SharedClasses"
Add- > Existing Item...
Browse to the "Shared Folder", include those shared classes. But those files are added physically into the folder "SharedClasses" rather than a reference. How do I just add a link to those shared files? Since these files might be modified from time to time, I don't want to delete and add those file frequently.
Even After successfull installtion of ASP.Net, I am not able to create ASP.net website.
It gives me error in image.I tried giving permissions to my account but no use.

View 5 RepliesI am having some trouble with my IIS web server & SQL reporting services.
At the current time my site is playing host to both reporting services (/reports & /reportserver) as well as my personal website (domain.com)
Only just recently have I implemented a Theme on my site and as such I have placed a statement in my web.config file directing it to apply a certain theme in the following manner:
<pages styleSheetTheme="General">
Because of this when I try to access the report pages it fails, telling me it couldn't find the Theme. So, what I did was locate the source files for the /reports & /reportserver directories and placed the App_Theme folder in them hoping that would sort everything out.
What I am getting now is the following error:
*Using themed css files requires a header control on the page. e.g. head runat="server" *
Does anyone know how I can get around this? Do I have to hack the SQL reporting aspx pages? I do NOT want to remove the web.config declaration.
i have database that is stored on local.user should also be able to upload the database to online server . i am able to save it on local .But it is not saving on server.It shows request time out. Is it due to server not allowing external access.

In my Views folder I have a several folders such as Category, Origin, Price. They all have a Browse.aspx file and the code in this file displays a table of products. All controllers associated with these folders use the same ViewModel, but in each view I have a repetitive code. The code is:
Folder Category, file browse.aspx
Folder Origin, file browse.aspx
.....
<% foreach ( var p in Model.Products) { %>
<li> <%: p.productname + " " + p.price + " " + p.origin.originname + " " + p.category.categoryname %> </li>

I am using gmail server settings to send emails for my asp.net website. Since there is a limitation on number of mails sent per day and limitations on sending to number of users, I cant use this service for long. Even If I use an idea to make sure I use multiple id's to send thousands of emails it will still not work.
I am taking care of all norms of subscribe and unsubscribe options, so that only registered users will receive mails.
I need to build a system which send mails accross thousands of emails * thousands of users per day. . I think this is possible, as emailers in twitter,facebook, orkut, linkeden work on same basis. Many of them use MailChimp Email Service.
But I am hosting my website on shared hosting (www.crystaltech.com) rather than dedicated server (Host Provider suggested me to go to dedicated server for my mail requirement). This host provider charges a lot to me if I include a dll, so I am not able to use dll. Is there any I can send bulk emails without using a dedicated server or dll.(Will use it in only in worst case scenario).My host providers said that they will be able to give service of sending only 800 mails per day. Are there any api providers for that. I have already checked with [URL]
I've tried to read and display the following RSS feed:

on my website using Syndication Classes but so far it does not work.
I've created two labels Label1, and Label 2 as well as one DataList in my asp web page, then I have tried to use XMLReader to read the feed but I think XMLReader can only read RSS feeds created in XMLWriter if I am correct.
I think the feed I am trying to read was not created in XML writer and there are some formatting issues. What is the best way to complete my task if I am not sure about the way the RSS feed was created?

I'm about to embark upon learning how to create a web site(in fact I am about to create a website for our company) which will enable users to place an order on our system. I already have a desktop, C# WPF, application that has some of the classes I am going to require in the MVC architecture of this new website. Can anyone advise me of the best practise to reuse these classes in the website. If I was going to create a new app I would refactor the classes out of the desktop app into a class library then add this to my new app by adding an existing project (my class library) to my solution but that option does not seem to exist in creating a website?

View 3 RepliesI am used to making separate Business Object and List<> classes for my DB tables. Sometimes I just have a basic task in hand as displaying a list of year for a search box or having some values in a drop down.
Right now I am ending up with a lot of separate classes and List classes<> for these basic operations.
How can I make a single class for some basic tasks as these by using generics? I want to have single class for some methods like get current year, employee names, Department Name/Code, Title etc. I am using .NET 2.0.
Edit
After some searching, I found that I can achieve similar tasks by creating a DTO namespace.
What I don't get right now is how to create multiple classes inside my DTO class. Say 1 class for just returning 'year', One for 'Employee Name/Code' and so on inside the single DTO class.
