I have created a basic website using ASP.net VB in order to display a diary of various user inputs to a website, I have created a register page, home page and once the use logs in it will direct them to a user logged in page where the entire contents of the diary database table are displayed, however I want the option when the user logs in the user will be able to see the entries that they have been created or been added to
I have created the following code used to return the entries from the database, basically I am selecting (displaying) for project diary name, start date, the creator of the diary, the diary user from the diary table in the database that the username entry field in the home page is equal to the diary creator or diary user (from the database). I am not too sure how I can relate the usernText.Text in the home page to connect to this page user_logged_in_page.
Code:Code:
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="SELECT [DiaryName], [StartDate], [DiaryCreator], [DiaryUser] FROM [Diary] WHERE '" & ~Home_Login/usernText.Text & = DiaryCreator or DiaryUser'">
PropertyName="usernText.Text" Type="String" />

I am a Windows forms programmer and I am familiar with the VB and VBA programming. Thus, I would like to ask:
** Can I directly start ASP.net without any prior knowlege of the ASP ? ** What is the best material to get learning the ASP.net from introductory level to the advance level?
I am a bit confused about the significance of the <form runat="server"> on a page, and its effect on Page and Control life cycles.
For long, I have eliminated any Postbacks or Viewstate from my web forms. I just use web forms to render (often very very complex) UI to the client (composed of server-side controls as well as ExtJs or jQuery widgets etc).
After the UI renders, all interaction with server is asynchronous through web-services or http handlers. So, lately I have started omitting the <form runat="server"> tage also from my web forms.
And to my surprise, the code has NOT broken. The life-cycle events are generated normally on all controls, they have access to normal ASP.NET processing pipeline, and they render perfect;y. As there are no Postbacks, I do not need ViewState or control events like click etc.
So, can somebody tell me if there's any material difference that <form runat="server"> would make in my scenario, or to ASP.NET page/control life-cycle??
After saving image in db how can we retrieve it in gridview like thumbnail size image and by clicking on image in gridview its open as preview. How can we do this in asp.net using c#.
Our customer has several security cameras at their site. These cameras transmit rtmpe streams that can be accessed by using the proper url. The video itself is flv. What the customer want is the ability to view these cameras on a website, both from internet explorer, and windows mobile 6.5. How can we do this, is there some kind of component we can use that we simply can parse the rtmpe url to, and it will go fullscreen and show the video? We need to handle input as well, both from mouse and a remote control, and we planned to use javascript for that. But for now, our biggest concern is how to play the stream.

1) I have a menu control which is using a SiteMapDataSource. This is bound to a .sitemap file. I have the orientation property set to horizontal, but for some strange reason it still displays vertical. I can't for the life of me figure out why it's doing this. Am I doing something wrong here?
2) Is there a way to not display the root (Home) directory on my menu control? I only want to show Customer Support, Technician Support, Administration, and Site Map on the control.
I've written this code to display a group of events when the value is 12/19/2010. This means each day I need to change the "default value" to the current date to display the events of the day. I would like to make this such that the change occurs automatically, that is, on 12/20/2010, I'd like to see just the events for 12/20/2010.
I am wanting to display an excel 2010 document in an asp.net web application. This document uses the new slicer functionality which I want to be available to the user.I know that excel 2010 docs can be used within sharepoint by inserting a web part which uses exceservices.But can it be achieved without sharepoint? Or can it be achieved using the the excelservices API to get the document from shreapoint and then somehow get it to the browser in .net?

I need to display the contents of a file selected from a ListBox into a text box. When I populate the ListBoxItems, I set the Text property to the name of the file and its full path to the Value property.
When I click the item, the page refreshes because AutoPostBack is on, but nothing happens. I then tried this:
VB.NET Code: Protected Sub lbLogs_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles lbLogs.SelectedIndexChanged Me.txtServiceTag.Text = Me.lbLogs.SelectedItem.TextEnd Sub
In my gridview, when in non-edit mode, my edit (pencil) and delete (X) buttons show up side-by-side as expected: Attachment 130089
However, when I click the edit button (pencil) to go into edit mode, the update (diskette) and cancel (undo arrow) appear as shown below, and the edit and delete buttons of the other rows appear the same "wrong" way as well. Attachment 130091

I have a development box running Win7 and VS2010. A User Acceptance Testing server running Windows Server 2008 / Sql Server 2008 and a Live server running Windows Server 2008 / Sql 2008.
When doing development I connect to a development database on the UAT server.
I have a problem that only occurs when I change the connection string to point to the database on the Live Server.
So, before I start describing the problem - the app works fine in development and when published to the UAT server - but there is a problem when I either publish it to the live server or, whilst on my dev box, point the connection string to the live database.
Here's an example.
I have a page with a gridview on it. In each row of the gridview there is a drop down list. All calls to the database are done through a Data Access class.
Say I have a function on an .aspx.cs page called GetDetails().
In this - to populate the Gridview I'll have something like ...
I have a website I''m developing and want to add an SQL databse to do some testing on my local pc. When I go through the process of adding an SQL Server DB it says
'Failed to generate an instance of SQL Server due to a failure in starting the process for the user instance. The connection willl be closed.'
I have created a basic website using ASP.net VB in order to display a diary of various user inputs to a website, I have created a register page, home page and once the user logs in it will direct them to a user logged in page where the diary entries that they have been created or been added to are displayed from the built in SQL database. I am trying to work with roles to ensure that when a certain login user is logged it will link them to a certain page (sort of like a basic admin page, but really its just to link to a page that only they can see).
I have used a session variable to take the username input and to display the diary entries they are linked to. How can I use another session variable to compare the role of the user that is logged in to allow me to direct them to the webpage that should link to their role. I have written code on the .aspx.vb that I thought would have worked, but it complies fine but doesn't work correctly. How can I write the code so that when the person inputs their details in, it would compare the username/password then to the role that they have been associated with in the database (these areas are all in the same table) that will then link to the webpage.
This is the error message I get on running the login page.Input string was not in a correct format.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.FormatException: Input string was not in a correct format.

Here's something I've been stuck on for some time. I used code from the ADO.NET Tutorial and tried to translate it so it applies to SQL and the database on my website. I set the Configuration Manager for Debug and so I can see a detailed error message.
I have most of the lines in the DoStuff Sub commented out right now but I get the same error message either way so it's responding to the first line below Try.
Here's the error message I see. Line 52 is : da.Fill(ds)
The table in Database1 that I'm trying to access is called Ray Rover Activation.
