Hello! I can´t show videos in WS.
I have a GenericHandler:
]]>
using System;
using System.Web;
using System.Data.SqlClient;
using System.Data;
using System.Configuration;
public class VideoHandler : IHttpHandler
{
private localhost.wsDataReader example;
public void ProcessRequest (HttpContext context)
{
example = new localhost.wsDataReader();
context.Response.BinaryWrite((byte[]) example.ShowVideo() );
}
public bool IsReusable
{
get {
return false;
}
}
}
If we only execute it shows a window for download the video: open, save or cancel.
This .ashx uses the WebMethod called ShowVideo():
using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
using System.Data.SqlClient;
[WebService(Namespace = "http://localhost/wsDataReader/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class wsDataReader : System.Web.Services.WebService
{
public SqlConnection ConexionConBD;
public SqlCommand Orden;
public SqlDataReader Lector;
[WebMethod(Description = "this method returns a video using DataReader")]
public byte[] ShowVideo()
{
string Conexion ="Data Source=.\\SQLEXPRESS;AttachDbFilename=\"|DataDirectory|\\BDvideos.mdf\";Integra" +
"ted Security=True;User Instance=True";
ConexionConBD = new SqlConnection(Conexion);
string Consulta = "SELECT Video FROM Videos";
Orden = new SqlCommand(Consulta, ConexionConBD);
ConexionConBD.Open();
Lector = Orden.ExecuteReader();
Lector.Read();
return (byte[]) Lector["Video"];
}
}
I don´t want download the video. I only want show the video in a WindowsFormsApplication or in a Website (.aspx)...
What can I do?

You can't really use a webservice if you don't want to download the video. Do you know anything about what a webservice is ?

Ok so how do you propose to move your eyeballs to the server. You need to research different way of displaying the video, get away from the idea that the vidio is not downloaded.

Hi there,
I’m trying to write a program that reads .xls file, formats it by removing specific rows and columns into table, sorts the data and then displays the data in dataGridView.
The .xls file is not formatted into table and in order to do that I need to delete 4 first rows and 2 first columns.
And here’s the problem when I’m trying to do that the program removes only 2 first rows and columns one and three instead of one and two. Here’s the code:
DataTable sampleDataTable = new DataTable();<br />
<br />
OleDbConnection aConnection = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\file.xls;Extended Properties=Excel 8.0");<br />
<br />
aConnection.Open();<br />
<br />
OleDbDataAdapter oleDbCommand = new OleDbDataAdapter("Select * from [file$]", aConnection);<br />
oleDbCommand.Fill(sampleDataTable);<br />
<br />
dataGridView1.DataSource = sampleDataTable;<br />
<br />
dataGridView1.Columns.RemoveAt(0);<br />
dataGridView1.Columns.RemoveAt(1);<br />
<br />
dataGridView1.Rows.RemoveAt(0);<br />
dataGridView1.Rows.RemoveAt(1);<br />
dataGridView1.Rows.RemoveAt(2);<br />
dataGridView1.Rows.RemoveAt(3);<br />
I don’t know what’s wrong as I tested it several times by programatiacally counting coulumns and rows but it’s still not working. It does work when I format the file before opening it by the program though.
Hope that somebody will point me in the right direction.
Thanks, Darius

One problem I can see is that after removing a row at index 0, the row that was at index 1 is now at index 0 (everything gets shifted).
So you would want this I believe:
dataGridView1.Columns.RemoveAt(0);
dataGridView1.Columns.RemoveAt(0);
dataGridView1.Rows.RemoveAt(0);
dataGridView1.Rows.RemoveAt(0);
dataGridView1.Rows.RemoveAt(0);
dataGridView1.Rows.RemoveAt(0);

Thanks howlett,
I just tried it and it worked, so now I can move further. Thanks again, Darius

Can anyone help me how to navigate a web page which has frames using C#. I need to click on a hyperlink automatically on a particular frame within the table of a website.
Regards...
|
|
|
|
|
do you know the id of the link and the frame in which the link migh reside? if you do then you can access the link using window.frames[...].document.getElementById("....") and call its click method from there. I'd suggest though that you look into Jquery. It is rich Javascript framework that will be a part of Visual Studio 2010. It makes traversing and manipulating DOM elements very easy. More information on Jquery is http://jquery.com/

Stream ftpstream = ftp.GetRequestStream();
error is
The remote server returned an error: (550) File unavailable (e.g., file not found, no access)..

GetRequestStream[^] on msdn with example to upload a file.
Dude this is the 4th time you ask this question, there are plenty of examples on the net; if you don't figure it out this time then maybe you should re-evaluate your entire code.

Yeah that documentation, its a bugger, only wish they didn't hide it under the clever name of msdn[^]. If they only had a way of remembering it easily, as if the internet where a book and that would be a page and you could bookmark[^] it..

Hi guys!
I wonder if anyone can help me figure out a thing because I think my head will explode soon if I keep head butting my keyboard
The problem is:
I inject from C# a DLL (coded in C) into a process.
The injected DLL hooks Winsock and give recv/send packets back to the controller (the C# program) through SendMessage/WM_COPYDATA.
So far so good, it works flawlessy.
Now I have the inverse problem. How can I give data back to the DLL?
For example the controller receive a specific packet from the DLL and tells it how to act. I dont want to add too much things to the DLL but keeping it pretty simple/small and make the controller do the hard work.
Hope I explained my problem enough
Thank you all in advance.

If I were you, I'd post the error here.

Use parameters instead of concatenation[^]

|

it will be nice if u paste ur error msg here though i find a prob with your code. I just want to be sure
|
|
|
|

It would be even nicer if you didn't use SMSSpeak to write your posts.
|
|
|
|
|
What is the error?
I somehow feel it is related to conversion. Check if txt is a valid date.

1) Oracle expects date to be in a certain format.
If your table name is MyTable with column MyDate, use bind variables to pass values. Do this:
sql = "Insert Into Mytable(MyDate) Values(:Date)";
OracleConnection conn = ...
OracleCommand cmd = conn.CreateCommand();
cmd.Parameter.AddWithValue("Date", Convert.ToDateTime(txt));
...

You can also use the 'TO_DATE(..)' function from Oracle SQL.
