Reading files from server and displaying links

30-Dec-07 6:40

I think that you are asking about how to use Reporting Service in ASP.NET. If we are using Reporting service, we used to have one project for reports and one project for website.

You can google about this if you want to get the sample.. ASP.NET SQL Reporting Service[^]

Hey all,

Just want to say I've used this site several times for help in the past and finally decided to join up and become a part of it. Before I ask my question I want you to know that I am not an experienced Web programmer. As of now I am strictly application based. I have a new, and somewhat small assignment ahead and I have an idea of how I would do it from an application side, so please let me know if this would work on the Web side as well.

The Problem -

We need a Web site that will look on our server for flash files and text files. The site will be pulling in some data from another program to let us know which videos and text files they need. On the web page it should have a link for each video avaliable in the folder. When they click on one it should take them to a page that displays the flash video as well as shows a text area with the contents of the text file that match that video.

One Solution -

Speaking of the page opening for the video to play, I thought it would be easier to use AJAX to embed the flash video in. Would this allow me to make the page more dynamic and not have so many individual pages? Or else, could I use one template page for the flash video and dynamically insert a different flash video object depending on which is clicked?

I know this may be a poor description, but it's the best I can explain in text. If anybody has any insight or thoughts on this please let me know. Thanks for reading and have a great day!

I think both ways will works. So, if you want "partial rendering", you should use Ajax and if you don't care about postback, Ajax won't be necessary..

Thanks for the input. I guess by "the problem" I mean the problem that I know what needs to but done but not exactly the best technique to go about doing it. Not sure how exactly I am going to list the files on the site for each file that is in the directory when I search for the files. Thanks for the reply.

ObjectDatasource Edit/Delete problem

Hi,
I want to work with some data with an ObjectDataSource. The data comes from a DB table which have two fields: ID (primary key) and Title.

I have created such a class:

[System.ComponentModel.ObjectData(true)]
class Biz
{
public Biz() {}

[System.ComponentModel.ObjectMethod(Select)]
public DataSet FetchAll() { ... }

[System.ComponentModel.ObjectMethod(Update)]
public void Update(int Serial, string Title) {...}

}

I have assigned this class to my ObjectDatasource. And I show the records with a Gridview control. Since ID field is PK it must not be update. so I make Id field Invisible or Readonly. Then when updating the records, only Title field is edditable. Afterwards, in Update method, Serial parameter is always 0 (becasue Id was not editted) and only Title field has a correct value. I need Serial field's value to update the Table because more than one person may have the same name. I have written a code in GridView's RowUpdating event and bypassed the Biz.Update method but I am quite sure it is a wrong job.

Please let me know what to do to make the ObjectDataSource update records by itself.

Thanks

Problem updating database

I am having a problem updating a table field in my database. Note that I am using Visual Web Developer 2008 Express.

I am using the asp_XYZ tables for membership, etc. My table (MyTable) contains a UserId field, which comes from the aspnet_Users table. The field I wish to update is MyField and is of type 'image'

I would like to populate my WebForm/FormView with MyField and allow the user to edit/update it. I do not have a problem populating the view, but cannot figure out the UpdateCommand. BTW, my SELECT command is something like this:

SELECT MyTable.MyField
FROM MyTable
INNER JOIN aspnet_Users ON MyTable.UserId = aspnet_Users.UserId
WHERE aspnet_Users.UserName = @UserName

I cannot figure out how to update. When I use the Configure Data Source wizard, it only allows me to choose fields from one table. I thought that I would be able to specify MyTable.MyField as a field to update and aspnet_Users.UserName as a field to filter. Confusion is setting in...

Since I thought I basically knew what my eventual UPDATE command was going to be, I went ahead and typed it myself. The following is that command and its UpdateParameters.

UPDATE MyTable
SET MyField = @MyField
FROM MyTable INNER JOIN aspnet_Users ON MyTable.UserId = aspnet_Users.UserId WHERE (aspnet_Users.UserName = @UserName)

asp:Parameter Name="MyField"
asp:SessionParameter Name="UserName" SessionField="UserName"

When I used the above command/parameters, the following exception was thrown:

"System.Data.SqlClient.SqlException: Operand type clash: nvarchar is incompatible with image"

Obviously, I am no SQL expert. Can someone explain where I am going wrong? Any comments on my approach are welcome.

Thanks.

Unable to work with IIS server

I think you need to define the type of parameter.

With SQL command, we used to do like that

<br />
this.sqlCommand1.Parameters.Add("@Picture",<br />
          System.Data.SqlDbType.Image);<br />
this.sqlCommand1.Parameters["@Picture"].Value=this.ImageByte;

If you are hosting the website on Windows 2003, you need to enabled the ASP.NET script in IIS.

Local CSS returns a 404?

Re: Local CSS returns a 404?

29-Dec-07 6:43

How the hell does this happen?

My CSS page for the site is not loading. Using firebug, it turns out that a 404 (File not found) is being returned. WTF? This is local to my machine, how the heck is this happening?

This is the first time it has happened but nothing is fixing it. I've restarted my laptop and still nothing Confused | :confused:

The website if File System Based rather than IIS based.

As you are using Firebug, you can check the url of 404 CSS. and if you got the url then I think you will be figure out the problem..

jQuery & ASP.NET

Mustafa Ismail Mustafa29-Dec-07 3:46

29-Dec-07 3:46

Is there a trick to including jQuery (the intent is to add ThickBox) into ASP.NET master pages?

It works fine on an html page, but when I add it to the master page, I get a "CS1056: Unexpected character '$'"

Here's the code in the of the master page:

<br />
<head runat="server"><br />
    <title>Untitled Page</title><br />
    <link type="text/css" rel="Stylesheet" href="../css/default.css" /><br />
    <link rel="stylesheet" href="../css/thickbox.css" type="text/css" media="screen" /><br />
<br />
    <script type="text/javascript" src="../js/jquery.js"></script><br />
<br />
    <script type="text/javascript"><br />
     jQuery.noConflict();<br />
     <br />
     // Use jQuery via jQuery(...)<br />
     jQuery(document).ready(function(){<br />
       jQuery("div").hide();<br />
     });<br />
     <br />
     // Use Prototype with $(...), etc.<br />
     $('someid').style.display = 'none';<br />
    </script><br />
<br />
    <script type="text/javascript" src="../js/thickbox.js" runat="server"></script><br />
<br />
</head>

Am I doing something wrong that I can't see? Confused | :confused:

Is that code required? (You are not referencing the prototype but you used $().) I think that you won't need this line.

how i can hide a row in a grid view

29-Dec-07 18:57

I tried for 2 days, VS2005 simply didn't want the JS, it didn't like it. Then again, I'm not a web developer and this project (my site) is setting out to improve that.

I'll tell you what, when I get back home from work today, I'll go through it again and give you a shout on this thread telling you what's happening. Deal? Smile | :)

Most error message are very informative nowadays. The error message that you got both explains the reason for the error and how to correct it.

A web.config file containing application level settings can only be placed in the root folder of an application. You have placed it in a folder inside an application. You have to configure the folder as an application in IIS using IIS Manager.

Experience is the sum of all the mistakes you have done.
