Hi,
You need to use callback to server.
you need to use AJAX. A good option is to use microsoft's implementation of AJAX(codename ATLAS).
Check here: http://ajax.asp.net/

Hello,
The customer wants to download a music file for a path that is on the server, then play that in the web form. So it will be like having window media player embedded in the web form itself.
I have the code for downloading and playing. However, a dialog will popup and when they click open it will play the music. However, the customer doesn't like this and want to play the music in a player that is in the web page itself.
Here is my code so far for downloading and playing the music.
Many thanks
<br />
Try<br />
Dim fs As FileStream = Nothing<br />
Dim contentType As String = String.Empty<br />
'Dim path As String = "\\10.10.10.31\Inetpub\wwwroot\csone\images\Content\"<br />
'Dim fileName As String = "Voice.mp3"<br />
Dim path As String = "C:\DownloadPicture\"<br />
Dim fileName As String = "Beethoven.wma"<br />
<br />
<br />
fs = File.Open(path & fileName, FileMode.Open)<br />
Dim fileBytes(fs.Length) As Byte<br />
<br />
fs.Read(fileBytes, 0, fs.Length)<br />
fs.Close()<br />
<br />
Response.AddHeader("Content-disposition", "attachment; filename=" & fileName)<br />
Response.ContentType = "application/octet-stream"<br />
Response.BinaryWrite(fileBytes)<br />
HttpContext.Current.ApplicationInstance.CompleteRequest()<br />
<br />
Catch ex As Exception<br />
MsgBox(ex.Message)<br />
End Try

Use an EMBED tag and the SRC should be
playmusic.aspx?musicfile=someid
Depending upon this querystring, appropriately stream the MP3 by setting the MimeType properly.

Hi,
I have a series of pages to create that will each have a bunch of listboxes on them, each containing a listing of files in a directory. I'm trying to get the page down to basics where i only have to plug in the correct paths to the folders, but I'm hitting a problem casting 'object sender' to a listbox - the SelectedItem is always the first item, not what was actually selected.
here is the entire code-behind (stripped down to basics):
public partial class departments_safety_play : System.Web.UI.Page {
private static readonly string year = DateTime.Now.Year.ToString();
private static readonly string root = @"../..//FIBRELINE/";
private readonly string pathFibrelineA = string.Format(@"{0}{1}/A-SHIFT/", root, year);
protected void Page_Load(object sender, EventArgs e) {
if (!IsPostBack) {
string folderToBrowse = Server.MapPath(pathFibrelineA);
utilityLib.ShowFilesInWithValue(folderToBrowse, lstFibrelineA, pathFibrelineA);
}
}
protected void lbSelectedIndexChanged(ListBox lb) {
string dir = lb.SelectedValue + lb.SelectedItem.Text;
string popupScript = "" +
"window.open('" + dir + "', 'CustomPopUp', " +
"'width=600, height=500, menubar=1, resizable=1, location=1')" +
"";
ClientScript.RegisterStartupScript(GetType(), lb.SelectedItem.Text, popupScript);
}
protected void SelectedIndexChanged(object sender, EventArgs e) {
ListBox lb = (ListBox) sender;
lbSelectedIndexChanged(lb);
}
}

Is it possible to loop through a database and display the names of all the tables? If so, please point me in the right direction.

I am trying to modify a webpage that includes the AJAX tools, but can not get AJAX installed. I have followed the steps using the Sample Web Site, but when I get to the point of adding the tool to the VS toolbar I get an error. “error loading types from Assembly…” “ Could not load file or assembly ‘System.Web.Extension…’ or one of its dependencies. The system could not find the file specified.”
I have VS 2005 Standard edition and have reinstalled ASP.NET.
Any idea what I might be doing wrong?

Hi,
I have a web service and if my web method catches an exception I then throw a new exception which is passed back to my calling application. Unfortunately though my exception has text XXXXXXX, it gets a load of other stuff added like this:
"System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Exception: ..."
It looks like I'm getting the inner exception trace.
How can I avoid this?
Thanks

Hi Friends
I am trying to pass value to my Session Variable from Javascript method.

{
var stringOne= "test";
Session.Add("Test", stringOne);
}
I am getting an error Session is undefined.
Any suggestions would be appreicated.
Thanks

Session is a Sever object not client, so you cannot access it in javascript code. You have to pass the string to the server either through querystring or through any form field and then get it on the server and add it to the session

Thanks Bhatti,
Can you please tell me how do you call a server side method from the Javascript?
Thanks

What are you really trying to do? You are in ASP.NET forum which means you have an idea how web forms works. So basically you add a ASP:Button in you page and onclientclick you call the javascript function, in that function you change the value of any hidden field or regular textbox and submit the form. And on server side you add the click handler to the button and in that eevnt handler you get the value of that field.
Please go through quickstart tutorials[^] to understand the whole flow.
e.g. you will call the following javascript function onclicentclick of the button:
<br />
function TestOne()<br />
{<br />
document.myform.stringOne.value = 'stringOne';<br />
docuemt.myform.submit();<br />
}<br />
and on server side in event handler for click event of button you will do this:
<br />
Session["Test"] = stringOne.Value;<br />

Hi all,
I have a multiline text box . I wan`t the user entered data to be filled in a single column of the table.But since the user can enter more than one line (by pressing enter or wrap i suppose).
It gives me an error that the data would be truncated. How should i enter the entire data in DB?
Also while reading i need to read it as a ordered list..How can we do that?
Any help would be highly appreciated
|
|
|
|
|
from the error it you are trying to save data that is larger than the allowed size in database. So either restrict the user to enter data for allowed size or increase the size in database.

what you mean by "you want to read it as ordered list"?

I have read a couple articles on how to encrypt portions of the web.config via command line, but is there any way to do something simillar when console/command line access is not available? such as in a hosted environment? I could possible make a request to the company hosting my asp.Net 2.0 site, but I thought that I had viewed a tutorial some time back where someone did it programatically.
P.S. Let me say to anyone that has noticed that this is my third quest for help this morning... I am new to this forum and promise to contribute back to the forum by helping others where I can. 8-)

What about doing this via cmd on your localmachine and update this portion in web.config from your host??
Thanks and Regards,
