I have a desktop application which uses BTree/Random Access files for it's core database function. It has run successfully from DOS up to 64bit Windows 7/8 for years now. Currently being developed and maintained with PDS 7.1/VB6 and VB.NET
I now have a fundamental requirement to add/delete/update records using a browser. My users need to host their own server in their office. They have a public facing IP address. Ideally the server should be a desktop machine (W7/8 64bit) which can be used to run the desktop app as well.
Low loading; possibly 100 - 200 requests per hour.
I cannot switch to a SQL type product as this would break my desktop app (proprietary BTree/Random Access architecture)
I am leaning to writing an HTTP server in VB.NET (there are many examples available and even some components).
I have the default membership table that was added automatically, then just used server explorer to add more columns, like FirstName, LastName, etc. In my code I can access all the default columns, but not the ones I created. Any thing special I need to do?
Here is how I access the table. using user. gives me all columns, but the one I created.
string userName = User.Identity.Name; MembershipUser user = (MembershipUser)System.Web.Security.Membership.GetUser(userName).ProviderUserKey;
I have created a DataSet which is connected to an Access Database. This DataSet is linked to a report and I would like to apply a filter to only display information relevant to the logged in user. My question is, if I wanted to add a parameter to the filter in my DataSet, what is the correct syntax when entering parameters? Whatever I try, it seems to convert automatically to a string.
How do I add a web.config to a class library? I'm trying to build a data access component with two classes, one class that represents one thing and the other to perform data operations on that thing. However when I right click the project and click add item, I don't see information for adding a web.config, I just see information for adding an app.config. Maybe I'm doing this wrong? I'd like this component to be available to other asp.net apps that I will build in the future....
1) i have a databse file on microsoft access. and i want to add system date in my databse using c#, what is the method to do this?
2) i m new in asp.net , i m making a demo application and storing a record of a person. there is a column of Date of birth. i used "datetime" data type for this column, because it have check on dates like i can't enter 29-02-2011, since its an invalid date. but problem with that it contain time with it, which should not be mentioned in date of birth column. plz guide me which data type shoul i use?

I've developed a web application and I've added some security features. Now i want to create a page for managing users and user access in my web application.Can anyone suggest some tutorial for managing users and access because i'm new to asp.net.
em all new in C# and .NET.I am following this tutorial: [URL]And i am at step 3: Adding Parameterized Methods to the Data Access Layer - i have No problems in getting out all information from my database.But when i try to get a specific item by CategoryID i get a Error.This is what i type in my Query in the table adapter:
SELECT ProductID, ProductName, SupplierID, CategoryID, QuantityPerUnit, UnitPrice, UnitsInStock, UnitsOnOrder, ReorderLevel, Discontinued FROM Products WHERE CategoryID = @CategoryID
Here is the error i get when i click finish:The wizard detected the following problems when configuring TableAdapter Query "FillByCategoryID":
Details: Generated SELECT statement. Error in WHERE clause near '@'. Unable to parse query text.
Getting the message that ObjectDataSource ... count not find a non-generic method ... that has parameters ... The parameter list is fine until I get to the very end and it list the two data fields that are in my DetailsView. Using the ASP Tutorial #17 (Examining the Events Associated with Inserting, Updating, and Deleting) and the Exploring the Data Modification - specifically the one showing the INSERT of the Product Name and UnitPrice. ASPX page is pretty simple and attempting something similar, two fields to insert a new record - update the other fields later.
Full Error Message follows along with ASPX and the AsignaturasBLL.cs. Interesting thing is that when I swap the two fields in the DetailView, then the last two fields in the error message are swapped. In the error message I bolded these two fields.
I just added System.Web reference to a dll assembly, the assembly is for windows applications and for web applications. IF the assembly will be deployed on a server, System.Web will be shared using GAC, and there is no overhead. But what about windows clients. I am wondering if there are extra resources or any kind of problems when System.Web is loaded into memory?
I want to change the web site where the IIS is. My desktop doesn't have IIS. Therefore, when I hit F5, the project will try launch my ASP.NET Web Application Project from http://localhost I needs to it to launched from [URL]. How can I change the configuration so the web page with URL starting as [URL]? I need it to confirm that the project is being served by the ASP .NET development server.
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?
I'm going to develop a desktop tool that will require a database.
How would I go about doing it in a way that will allow me to post the code to a website so that all of the desktop applications see a new version and download the database.
I am developing one Intranet Que type project for a small Travel agency. I need one logic to route the customer que over all sales agent so anyone once free he will be buzzup to pickup the customer till here is Okay. But i need some timeout if no sales agent pickup the Que it will forward to the supervisor. Now here is my Question should i make a small desktop application and run in server to moinitor the time and forward the task.... or Is Web Service is suitable for this? (Forward means just it will update one field of table so it will start displaying in Supervisor screen.)
Is there a way to make a desktop application easily interfaceable via Web ? Meaning, can you have a way to interface with a single desktop application as if you were remote desktop'd into the machine but not? I am looking at doing this in ASP.NET or Silverlight.
I have just started learning C#. Can anyone explain the technical differences between a .Net desktop application and a web application? I mean for example, if I have a simple HelloWorld application using a WinForm, what are the steps required to change that into a HelloWorld web application?
Is it possible to connect to a Remote Desktop from my ASP.net (I easily done it in .net windows application with a 4 line code and"Windows Terminal Service Control")application, If so can you guide me through it. Many thanks in advance.NB:I want to achieve it without using ActiveX control that work in IE, because with that every client would have to use IE and install the control.
I am trying to develop a web application(Using ASP.NET and c#) that uses a specific database hosted on web server. I will have another desktop application that will use a local database. Both databases have same structure and data at start up. Then databases will change when users add data to web application and an employee adds data to the desktop application. After a while I have to sync both databases.
What will be best way to do this? Is there any opensource example/ starter kit to start with?
I would like to embed a Remote Desktop session within my browser. I must use remote desktop because my clients can't install any additional software on the server.
Here are some problems that I can already foresee:
1) I believe that I can embed an RDP ActiveX control, but then all I could support is IE. And even then, IE lockdown may forbid ActiveX controls.
2) I don't know anything about Apple computers, but I presume that they don't inherently run RDP?
3) I think there are ways to run RDP through a Java control. I don't have experience to know if this is a good or bad idea. I suppose that Java may even be disabled on some browsers, but don't know if this is a common case?
