Hi All,
I am using HttpWebRequest and HttpWebResponse object to upload a file over HTTPS Channel.
My code works fine when I upload a small size file (Less than 2K). When I try to upload a bigger file, HttpWebRequest is Timing Out.(The operation has timed-out.)
Here is the snippet of the code I am using
HttpWebResponse Resp = (HttpWebResponse) Req.GetResponse(); Stream responseStream = Resp.GetResponseStream(); Encoding enc = Encoding.GetEncoding(1252); // Windows default Code Page
StreamReader loResponseStream = new StreamReader(responseStream,enc);
string stringResponse = loResponseStream.ReadToEnd();
LogFileStream.WriteLine("Http Response: " + Resp.StatusCode + " " + DateTime.Now.ToString().Trim()+"\n");
responseStream.Close();
oResponseStream.Close();
Does any body having clue what to do in such kind of scenario??
Thanks in advance.

I am using a calendar control in my application(Visual Studio 2005, C# .NET 2.0). As per the control, clicking on the calendar textbox, a calendar should popup just below the textbox. I am facing two problems with the control. First problem is, when I am clicking on the text box(calendar control) the calendar is popping up but it is displaying under the other controls below. Second problem is, if I am using more than one date control in the same page, one of the calendar is getting displayed in top left corner of the page permanently. The calendar control is inside a "div" tag. Is this the problem?

Using Globalisation for ASP.Net Can a Web appplication can take the user input in different laguages. Like for example my culture is fr-Fr french then Can a user enter the data in french in the textbox control.

UICulture has no connection with the language the user can use for entering data. The user can even enter data in Chinese. UICulture is used to display the correct date format etc on a website.

If you hide a panel, it should hide all the controls as well. If this is a web app, a PlaceHolder is the best way to group things so they all show and hide together.

If you set panel.Visible = false, then all controls in that panel will be invisible too.

i'm using the visible poperty to hide the panel but it doesn't hide the controls on the panel.
is there any other way other than through the visible property.

please give solutions about said problems.
thank you 
My source code
==============
namespace WindowsApplication1
{
public partial class Form1 : Form
{
private DataTable dataTable1;
private OleDbConnection oConnOLEDB = new OleDbConnection();
private OleDbDataAdapter oAdapter1 = new OleDbDataAdapter();
private OleDbDataAdapter oledbSelectCMD = new OleDbDataAdapter();
private DataSet dataset1 = new DataSet();
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
try
{
oConnOLEDB.ConnectionString = "Provider=MSDAORA.1;Data Source=ORVB;Persist Security Info=True;User ID=RIAZ;Password=SMS";
oConnOLEDB.Open();
}
catch (OleDbException ex)
{
MessageBox.Show(ex.Message, ex.Source, MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
private void button1_Click(object sender, EventArgs e)
{
String strSQLCommand = null;
strSQLCommand = "SELECT * FROM ADMIN.SCHEDULE ORDER BY TDATE DESC";
dataset1.Clear();
oAdapter1 = new OleDbDataAdapter(strSQLCommand, oConnOLEDB);
oAdapter1.Fill(dataset1, "SCHEDULE");
dataGrid1.SetDataBinding(dataset1, null);
}
}
}

1) Make your datagrid readonly
2) Use DataSet.Tables[0].DefaultView.

dear all,
i have created an arrylist in one class i add object to it from the same class.
how can i remove object from the same arraylist from another class if u have any piece of code please do provide me.
thanx alot

You probalby need to post some code. The best way to do this is to have the class that exposes the arraylist to expose methods to add and remove items. Or use delegates to send a message to the class in question.

You must have a reference to arrayList in Class1 in Class2.
Sample:
using System;
using System.Collections;
class Program
{
static void Main(string[] args)
{
MyClass1 myClass1 = new MyClass1();
myClass1.AddABC();
MyClass2 myClass2 = new MyClass2(myClass1.MyArrayList);
myClass2.RemoveABC();
}
}
public class MyClass1
{
private ArrayList arrayList = null;
public MyClass1()
{
this.arrayList = new ArrayList();
}
public void AddABC()
{
this.arrayList.Add("ABC");
}
public ArrayList MyArrayList
{
get { return this.arrayList; }
}
}
public class MyClass2
{
private ArrayList arrayList = null;
public MyClass2(ArrayList arrayList)
{
this.arrayList = arrayList;
}
public void RemoveABC()
{
this.arrayList.Remove("ABC");
}
}

Hi
The simplest way is declare the ArrayList as public static and access directly through the class name.

I want to create a directory using post build event at a specified path before copying my files into that directory. presently, i am facing a problem of post build error, if directory does not exist. I want to provide a command in post build to create directory first then it should copy.
Thanks in advance

MKDIR [path] will create a directory with the specified path.

How can I remove a method from System.Collections.CollectionBase?
Say, I have a class:
public class MyList : System.Collections.CollectionBase{}
I have all the members of the collection base such as Add(object), Remove(object), RemoveAt(index), etc...
I want to get rid of RemoveAt() and Insert() methods..
Do you have a solution?
Thanks in advance..

You can't remove methods that you inherit.
You can override them with methods that throws InvalidOperationException, or you can encapsulate the collection in a class that only exposes the methods that you want.

You have a couple of options:
1. Do not derive from CollectionBase and instead implement ICollection and/or IList directly. This will allow you to either not include undesirable insertion/removal methods or, where those methods are required by the collection interfaces, to throw a NotImplementedException.
2. Derive from CollectionBase but override the protected OnInsert() and OnRemove() methods and throw a NotImplementedException. (You have to be careful with OnInsert(), though, as that will also get called for Add(), which you *do* want to allow.)

My problem is in this line of code: strResponse = wcDownload.OpenRead(UpdateUrl);
the variable strResponse receives a null value, and blows up.
I know I am going to need to figure out how to handle this exception, I know the url i am trying to access works because earlier in the code i check the modified date with today's date and it calls this method.
Here is my download method
private void Download()
{
using (WebClient wcDownload = new WebClient())
{
try
{
// Create a request to the file we are downloading
webRequest = (HttpWebRequest)WebRequest.Create(UpdateUrl);
// Set default authentication for retrieving the file
webRequest.Credentials = CredentialCache.DefaultCredentials;
// Retrieve the response from the server
webResponse = (HttpWebResponse)webRequest.GetResponse();
// Ask the server for the file size and store it
Int64 fileSize = webResponse.ContentLength;
// Open the URL for download
strResponse = wcDownload.OpenRead(UpdateUrl);
// Create a new file stream where we will be saving the data (local drive)
strLocal = new FileStream(FilePath, FileMode.Create, FileAccess.Write, FileShare.None);
// It will store the current number of bytes we retrieved from the server
int bytesSize = 0;
// A buffer for storing and writing the data retrieved from the server
byte[] downBuffer = new byte[2048];
// Loop through the buffer until the buffer is empty
while ((bytesSize = strResponse.Read(downBuffer, 0, downBuffer.Length)) > 0)
{
// Write the data from the buffer to the local hard drive
strLocal.Write(downBuffer, 0, bytesSize);
// Invoke the method that updates the form's label and progress bar
this.Invoke(new UpdateProgessCallback(this.UpdateProgress), new object[] { strLocal.Length, fileSize });
}
}
finally
{
// When the above code has ended, close the streams
strResponse.Close();
strLocal.Close();
UpdateFlag = false;
}
}

I have no idea what you mean. Do you want to write a windows hook so you capture events outside your program ?
