Thanks for answering
Does this cause the page to reload? I need something really fast: It's for realtime video.

Yes. It causes the page to reload. Sounds like you have a more complicated situation.
You might want to give a more detailed explaination of what you are trying to accomplish and the folks here can point you in the right direction.
There may even be a solution aleady developed here or at CodePlex http://www.codeplex.com/[^]
The people here are very helpful.
Good luck with your project.

what I'm trying to do is to make a Windows Forms Application that grabs images from some cameras. It processes the images and stores results, keeps statistics and so forth. Then I want to develop a Web Application that communicates with the other, displaying real time images grabbed, and being able to configure different parameters like pan, tilt, zoom, processing thresholds, etc.
I'm just beginning with C# and ASP.NET and I feel a bit lost... 
By now I'm able to transfer images from the WF application and displaying them on the ASP.NET one. But I need to use buttons. By now I'm trying to implement some sort of messaging or callback functions to display the image on the ASP.NET app each time a new grabbed image is received.
Hope this helps a bit more.
And I've seen it in these first days here, people is pretty much helpful...

Ah ...
Hmm. Sounds like you want to have the web page automatically update based on an event (like a new image).
This is a bit out of my realm. I could only offer the idea that you create a javascript timer that calls out to grab any new data that might be available. This is not the most elegant way to do things, but it would work. 
Clearly, the more advanced guys here could offer you a better solution.

Yes.. Just make an AJAX request for latest updates continuously using SetInterval of Javascript. Let after every 30 seconds your page sends a server request to an HTTP handler placed in the server. This handler will give you appropriate response when new images are refreshed or return nothing...
By this way you can update your client site properly with latest updates.
But mind that, making too much calls to the server means lots of server bandwidth might be considered.
So if you want to avoid extra server calls, I would recommend to use Silverlight which can hold TCP channel from the client.
Thus it is easier to handle this in case of silverlight.
If you want only HTML, then there is no other way than to call XMLHttpRequest 's continuously. ...

I am using a GridView to get access to (.pdf) files returned from a database search. The applicable column will always be indexed at [6] but the ROW will vary depending on the users selection. I am using this snippet to get the (pdf) name so I can pass it to the Process.Start() for Adobe:
____string pdf = GridViewResults.Rows[0].Cells[6].Text;____.
There are two issues that are giving me a problem. First is how do I get the ROW number of the selected line in the grid. The second is this; I have tied the code to the "SelectedIndexChanged" event because there apparently is no "Click" event for the grid (as in C# Apps), but when I run the application, the event is not firing. I looked for an AutoPostback setting with the idea that it might be required to reset the page, but there is none for the GridView. Where do I go from here?
Thanks in advance for the help...Pat

Hi,
I have a button which needs to download the file, simaltaneously it has to enable or disable the linkbutton on a click event. I went for the following code which never works for me.. The problem is there in writing the file in response. Any idea is highly valuable.
Thanks in advance..
Given the code below..
----
LinkButton1.Enabled = false;
System.IO.FileStream fs = null;
fs = System.IO.File.Open("c://4377.doc", System.IO.FileMode.Open);
byte[] btFile = new byte[fs.Length];
fs.Read(btFile, 0, Convert.ToInt32(fs.Length));
fs.Close();
Response.AddHeader("Content-disposition", "attachment; filename=4377.mpp");
Response.ContentType = "application/octet-stream";
Response.BinaryWrite(btFile);
Response.End();
-----------
Thanks

Are you getting an error?
If you want the link button to be disabled once you've clicked it and the page is processing you'll have to use javascript to disable it.
|
|
|
|
|
Used the javascript option but there is no use. It remains the same.
I called the javascript function in the clientclick event of the button and gave the following line.
document.getElementById("LinkButton1").disabled=false;
Thanks

You will need to use the client id of the link button in your javascript, something like:
document.getElementById("<%=LinkButton1.ClientID%>").disabled = false;

<Description>Converts BBCode to XHTML in the comments</Description>

<AdminPage />
<Enabled>true</Enabled>
so and so ..... but it is opening in the existing window ..please help me..

This code is looking fine.Did you check the view source whether this is rendering properly or not?
|
|
|
|
|
|
If it is an anchor tag, please ensure you are using html.
Also if you want this anchor tag to be placed on an HTML document please use
<a href="http://dotnetblogengine.net" target="_blank" >BlogEngine.NET</a>
rather than
<a href="http://dotnetblogengine.net">BlogEngine.NET< target="_blank" /a>
as target ="_blank" is misplaced on your place.

I'm reading excel file data using sql bulk copy and uploading the same inside sql server database:
My current code is:
public bool ImportMethod()
{
string sqlConnectionString = "Data Source=192.1.1.10;Initial Catalog=GePReleaseStatus;user=sa;password=sa;Integrated Security=True";
//Create Connection to Excel WorkBook
using (OleDbConnection connection = new OleDbConnection(excelConnectionString))
{
connection.Open();
OleDbCommand command = new OleDbCommand("SELECT SrNo AS SrNo,Module AS vcrModule,DefectNoClientName AS intDefectNo, FeratureID AS intFeratureID,Priority AS vcrPriority,Description AS vcrDescription FROM [eContract_4.0.13$]", connection);
using (System.Data.Common.DbDataReader dr = command.ExecuteReader())
{
// Bulk Copy to SQL Server
using (System.Data.SqlClient.SqlBulkCopy bulkCopy = new System.Data.SqlClient.SqlBulkCopy(sqlConnectionString))
{
bulkCopy.DestinationTableName = "ExcelData";
bulkCopy.WriteToServer(dr);
return true;
}
}
connection.Close();
}
}
Now the problem is:-
1) I'm unable to read the excel, as it has formatted cells at top ?
(common error: IErrorInfo.GetDescription failed with E_FAIL(0x80004005).)
2) how to read the excel from any particular row ?
3) Is it possible to read multiple sheets from a single excel file, how ?
Thanks

Hi,
I am developing a webapplication in Visual Studio-2008(AsP.net/C#). I am trying to integrate my webapplication with webservice.The webservice is such that it will put all my request in asynchronous mode.
My webapplication, I am sending a mail with Cc and Bcc fields, for the body of my mail I am using a rich textbox from richer components.
Rich text box is used to send the data in formatted text.
I am using the code below:
Service webServ = new Service();
// Make an Asynchronous Call by calling the start method.
webServ.BeginSendMailAll(dsRec, strSubj, RichTextBox1.Text , new AsyncCallback(WsCallback), webServ);
while using the webservice how to implement: The Bcc and Cc in the code above.
Also the body of the mail goes(to the recepient) in html format, instead of the fromatted text I am sending.
please help me out
thanks

Sounds like you need to make changes to the actual webservice code to make it do what you want it to.

Is this a question ? If 'reportviewer can't run on the internet', then you need to find some other way of doing whatever it is you want to do, surely ?

You won't find any, because the question is illogical. ASP.NET apps are all mobile by definition, they run in the browser. They also run off a server, so you won't write something to run on a mobile device in ASP.NET.
Or do you mean detecting the browser type and working out if it's a mobile device ? You don't need a tutorial, you just examine the browser type and redirect to a subsite that draws itself to fit, or write every page to change it's format accordingly.
