I've been using the code below to read from a database (found on this site a while back), but I'd now like to modify it to UPDATE a value. I'd be grateful if someone could show me how to change it?

Creating a system with web front end and SQL backend (microsoft obviously). I have tried using the asp.netsqlprovider but i can;t as i am only allowed one database on the server, so i then tried to update my current database with the triggers to input the schema into the already existing database.Next step i create my own table with two simple fields of username and password and try and authenticate that way, i can't get that to work either.
I ahve limited permissions on the network as i am a University Student. I really don't know what to do. Never had to create a log on system before and i thought it would be far simpler than this. I ahve used Microsoft's sqlprovider schema before and it worked fine. I have also authenticated via IIS and AD too before. I can't do any of those two in this instance it seems.I need an alternative for logging in users, if needs be in can be crude. I also still need to have some kind of two different views too for logged in users and not logged in users, but that can change if needs must.Don't let me down people, haha. Think this posts in the correct place, i could not find another one i thought could be more relevant.

//Create a connection to the database
MySqlConnection conn = new MySqlConnection("Database=kid07025;Data Source=195.178.228.254;User Id=kid07025;Password=********");
//open the connection
conn.Open();
//MySQL Query which updates the row where Anvandarnamn = Anvandarnamn (recieved from a cookie)
MySqlCommand cmd = new MySqlCommand("UPDATE personer SET Information=?Information,Fnamn=?Fnamn,Enamn=?Enamn,Personnr=?Personnr,Adress=?Adress,Postnr=?Postnr,Ort=?Ort WHERE Anvandarnamn=?Anvandarnamn", conn);
// Update with new text
cmd.Parameters.AddWithValue("?Anvandarnamn", Request.Cookies["Anvandarnamn"].Value);
cmd.Parameters.AddWithValue("?Information", TextBox1.Text);
cmd.Parameters.AddWithValue("?Fnamn", TextBox2.Text);
cmd.Parameters.AddWithValue("?Enamn", TextBox3.Text);
cmd.Parameters.AddWithValue("?Personnr",TextBox4.Text);
cmd.Parameters.AddWithValue("?Adress", TextBox5.Text);
cmd.Parameters.AddWithValue("?Postnr", TextBox6.Text);

I don't know what I am doing wrong here, but the database doesn't get updated when I press the button.
I use VS 2010, ASP.NET
I have several web sequential pages which will modify a record and its child records in the database, called a "project". Such a project is currently passed between pages using its database ID in the URL parameters.
A project has some information specific to itself, and also consists of one or more Tasks, which each have information specific to itself.
Is it faster (alternatively, more maintainable or more easily understood) to hit the database each time I need to query the same project (and its tasks), or should I query the database once (either once for each page or once for all pages and save to Session) and check the saved object rather than the database?
This is a very common error as evidenced but the very large number of problems and suggested solutions on the web. I finally got around it last week but can't remember what was the step that did it. At that time, I was building a web application rather than a web site. Is that the difference? As you can see, it is no longer in the APP_DATA folder and is named membership.mdf rather than aspnetdb.mdf. I ran aspnet_regsql.exe to create it and actually had it working and was updating it successfully. But for other reasons, I had to scrap the application and decided to re-create it from scratch as a web site rather than a web application. I had been using Visual Studio 2008 to build the web application but am now using Visual Web Developer 2008 Express Edition to build the web site. Unfortunately, the Visual Studio application will no longer open so I can't verify that the web application still works. Can anybody help? (Please!!!) BTW, ASPNET and NETWORK SERVICE both have full control over the membership.mdf.

Web service error response (code/message etc) would you store it in a database? or would you keep the error response in a method.By the time I'm done with this, there will be hundreds of error response, maybe in the future, thousands? (I dont know yet, depends how large this web service grows).EDIT: error response is the response returned back to the application via the web service, (not to be confused with error logging).

View 10 Replieswhen I update Adobe Flash/Flex code that is not related to ASP.Net with TortoiseSVN (latest) on a Windows Server 2008, the complete website locks and stop responding.Is it ASP.Net recompiling my code, is it IIS 7 or is it Tortoise locking the file system?How can I prevent or minimize this if I need to do an update when 1000 users are using the ASP.Net website?
View 2 RepliesI know that you can call an update on an UpdatePanel server side by calling the Update function on it. I have done this in the past, though in the past I also had a ContentTemplate. In one of my current projects I add all of the controls to a the UpdatePanel in the code behind so there is no ContentTemplate defined. Is there a way to update the UpdatePanel from the code behind despite this, or am I barking up the wrong tree?
<asp:UpdatePanel runat="server" updatemode="Conditional">
<ContentTemplate>
<asp:PlaceHolder runat="server" />
</ContentTemplate>
This is with ASP.NET Web Forms .NET 2.0 - I have a situation that I am not sure how to fulfill all the requirements. I need to update an img source on the page if selections are made from a drop down on the same page. Basically, the drop downs are 'options' for the item. If a selection is made (i.e. color: red) then I would update the img for the product to something like (productID_red.jpeg) IF one exists. The problem is I don't want to do post backs and refresh the page every time a selection is made - especially if I do a check to see if the image exists before I swap out the img src for that product and the file doesn't exist so I just refreshed the entire page for nothing.QUESTION:So I have easily thrown some javascript together that formulates a string of the image file name based on the options selected. My question is, what options do I have to do the following:submit the constructed image name (i.e. productID_red_large.jpg) to some where that will verify the file exists either in C# or if it is even possible in the javascript. I also have to check for different possible file types (i.e. .png, .jpg...etc.).not do a post back and refresh the entire page

I am doing a countdown with a timer that runs every second. I have a scriptmanager, but how do I make it update behind the scenes so the user does not see it? I thought I could use an update panel, but I can't get it to work right.
View 1 RepliesI am trying to use an update panel to run some server sided code. everything works fine with this:
asp Code:
<script runat="server">
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Label1.Text = "Refreshed at " & _
DateTime.Now.ToString()
[Code] ....
The problem is this: when the page first loads, i have a text box that i add a string to. if its a normal string, its fine. but, if its an XML string, the update panel will stop working (no errors, it just wont refresh the panel when the button is pushed). i'v tried narrowing the cause down and found it does not like "<" character.
I tried using this: Server.HtmlEncode to encode the xml but there must be other characters in the string it does not like (the XML is a response from the Linkedin API) .
how i can remedie this? even if the Server.HtmlEncode worked, its not the ideal solution, as i want to display the XML not the decoded string.
I want to run code at the server(sql update) on a client button click, but i dont want a postback (more specifically, page flicker or loss of scrolling position).
How would I do this?
I want MVC pattern to save,update,delete.with detail code
View 3 RepliesI have a detailsview which I am populating using a SQLDATASOURCE, which is bound to a table in a SQL db. Because the number of columns in the table will change, I am using SELECT * from [TABLENAME] to populate the view, this works fine.
My problem is that I need to also be able to update the table and I thought the best way was to generate the updatecommand in the code behind. This is no problem, code is as follows:
[Code]....
But the next stage is to create the relevant parameters for the update command. Does anybody have any thoughts on this? All of the information I have found for the updateParamater reference knowing the final value.
What I really need to do is the code behind equivalent of
<asp:Parameter Name="PARAMETERNAME" Type="Int32" />
Not sure whether this is possible.
