Did you even try once to find the reason.
A simple google search would have helped you and saved a lot of your time. Plus, learning things yourself will help you improve. 
In between, have a look at this[^].

When you are getting this error? Did you searched in google for Error Code 404?

404 usually indicates that the client was able to communicate with the server but the server could not find what was requested.
You need to check the uri for the webservice.

Hi....
I am using HttpFileCollection for uploading multiple files.
It works fine,but problem arises when i am using same HttpFileCollection in another SendExternalMail().
I am not getting byte values.its bytes values are zero.
Here is the code.
public void SendInternalMail()
{
HttpFileCollection hfc = Request.Files;
if (hfc.Count != 0)
{
for (int i = 0; i < hfc.Count; i++)
{
if (!string.IsNullOrEmpty(hfc[i].FileName))
{
Int32 File1Length = hfc[i].ContentLength;
Stream File1Stream;
File1Stream = hfc[i].InputStream;
//Here i am getting proper byte values
byte[] btFileContent = new byte[File1Length];
File1Stream.Read(btFileContent, 0, File1Length);
IsZip = 1;
string strflname = hfc[i].FileName;
strExtension = System.IO.Path.GetExtension(strflname);
strflname = System.IO.Path.GetFileName(strflname);
strImageType = hfc[i].ContentType;
if (strImageType == "image/pjpeg" || strImageType == "image/bmp" || strImageType == "image/gif" || strImageType == "image/x-png" || strImageType == "image/tiff")
{
objZipUnZip.UploadImage(strflname, btFileContent, strImageType, File1Length, Convert.ToInt32(Session["UserCode"]), out objCode);
strVal = strVal + objCode + ",";
}
else
{
if (objZipUnZip.ZipFiles(btFileContent, strflname, strExtension, IsZip, Convert.ToInt32(Session["UserCode"]), out iFilecode))
{
strVal = strVal + iFilecode + ",";
}
}
}
}
}
public void SendExternalMail()
{
string strAttach = string.Empty;
string strSendAttach = string.Empty;
string strFileName = string.Empty;
string strFileAttachment = string.Empty;
bool bFlag = false;
for (int i = 0; i < hfc.Count; i++)
{
if (!string.IsNullOrEmpty(hfc[i].FileName))
{
Int32 File1Length = hfc[i].ContentLength;
Stream File1Stream;
File1Stream = hfc[i].InputStream;
//Here i can't get byte value,all values are zeros
byte[] btFileContent = new byte[File1Length];
File1Stream.Read(btFileContent, 0, File1Length);
IsZip = 0;
string strflname = hfc[i].FileName;
strExtension = System.IO.Path.GetExtension(strflname);
strflname = System.IO.Path.GetFileName(strflname);
strImageType = hfc[i].ContentType;
if (strImageType == "image/pjpeg" || strImageType == "image/bmp" || strImageType == "image/gif" || strImageType == "image/x-png" || strImageType == "image/tiff")
{
objZipUnZip.UploadImage(strflname, btFileContent, strImageType, File1Length, Convert.ToInt32(Session["UserCode"]), out objCode);
strVal = strVal + objCode + ",";
}
else
{
if (objZipUnZip.UploadFile(strflname, strExtension, btFileContent, IsZip, Convert.ToInt32(Session["UserCode"]), out iFilecode1))
{
strVal = strVal + iFilecode1 + ",";
}
}
}
}
}
Kindly help to solve this issue.
Thanks.

Hi All,
I have one datarow which contains some rows. Now i am copying values from datarow to arraylist using forloop.
But this is again taking some time.
Now i want copy values form datarow to arraylist or array without using forloop.
Is there any way to implement this using LINQ or any other concept.
The code which i used is mentioned below.
DataTable myTable = null;
DataRow[] foundRows = null;
ArrayList RequiredList = new ArrayList();
Array[] arrayForData = null;
ArrayList arrayListFordata = new ArrayList();
DataSet dsForData = null;
if (Session[strSessionDataList] == null)
{
CatalogController _controller = new CatalogController();
Session[strSessionDataList] = arrayListFordata;
}
else
{
dsForData = new DataSet();
dsForData = Session[strSessionDataList] as DataSet;
myTable = dsForData.Tables[0];
if (myTable.Rows.Count > 0)
{
foundRows = myTable.Select("val like '" + item + "%'");
arrayForData = new Array[foundRows.Length];
foundRows.CopyTo(arrayForData, 0); This is not working, it is giving runtime error like type mismatch
//for (int count = 0; count < foundRows.Length; count++)
//{
// RequiredList.Add(foundRows[count].ItemArray[0].ToString());
//}
//for (int count = 0; count < myTable.Select("val like '" + item + "%'").Length; count++)
//{
// RequiredList.Insert(count, myTable.Select("val like '" + item + "%'")[count].ItemArray[0]);
// //foundRows.ItemArray[count] = myTable.Select("val like '" + item + "%'")[count].ItemArray[0];
//}
}
}
if (RequiredList.Count == 0) RequiredList.Add("Fail");
//return RequiredList;

I want to maintain state of checked option when i click on previous/next button

Solution 1:
Store in session
Solution 2:
Create a temporary datatable and keep on updating the radio button status there.

hello
Reading this article on TreeView control...[^], it shows how to either bind a xml file on disk to TreeView control via "XmlDataSource"
<br />
<div><br />
<asp:TreeViewExpandImageUrl="Images/closed.gif"<br />
CollapseImageUrl="Images/open.gif"ID="TreeView1"<br />
Runat="server"DataSourceID="XmlDataSource1"><br />
<DataBindings><br />
<asp:TreeNodeBindingDataMember="Category"<br />
ValueField="ID"TextField="Name"><br />
</asp:TreeNodeBinding> <br />
<asp:TreeNodeBindingDataMember="Description"<br />
ValueField="Value"<br />
TextField="Value"><br />
</asp:TreeNodeBinding><br />
</DataBindings><br />
</asp:TreeView> <br />
</div><br />
<div><br />
<asp:XmlDataSourceID="XmlDataSource1"Runat="server"<br />
DataFile="~/Data/Categories.xml"><br />
</asp:XmlDataSource><br />
</div><br />
My question are:
1. how can we bind an in-memory (not on disk) XmlDocument object to a XmlDataSource? and thus TreeView control? In the article author has suggested an alternative - OnTreeNodePopulate event - however, this is not suitable for my case as my whole list/hierarchy is loaded in one go, not once-per-node.
2. how can we set navigation Url? in standard "web.sitemap", you can do this with siteMapNode's "Url" attribute. But now that, as in above example, uses my own custom Xml... how do we do this?
Thanks

Hi I am populating a Dropdownlist using clientside script.Later, when I am trying to access the dropdownvalue from server side code,it's coming blank.
I have tried the following:
string val=DropDownList1.Text;
I have also tried
string val=DropDownList1.Attributes["value"];
But none worked.
Please guide me to solve this.

If you are populating the Dropdown using client side script(JavaScript), then you cannot read dropdown value at server.
Dropdown clears when page post back.
If you need to read the value, save the selected value of dropdown into the hidden text box, using JavaScript(Before Page Post Back). Now read the textbox value.

Thanks Aman ....that's a great n working reply....even i was also thinking of the same solution.

Hi fellow coders,
I'm trying to do a HTTP GET request but I get this error: Unable to read data from the transport connection.
Below is my code:
Dim web As New System.Net.WebClient
Dim stream As Stream = web.OpenRead(URI)
Dim reader As StreamReader
reader = New StreamReader(stream)
strResult = reader.ReadToEnd
Note I cant do POST as the URI does not support that.
Thank you in advance.

This question has NOTHING to do with ASP.NET

You never do a webclient request in ASP.NET? well, then too bad...
|
|
|
|

Just because it's *possible* to do something in ASP.NET, does not make it an ASP.NET question. If I can do it in a winforms app, then it's just a C# question.

Some people are just not helpful are they?
If you got nothing to say, then dont reply!
If I'm wrong then you can at least point me to the right direction, you dont have to sound so rude you know!

FYI when people are incapable of even working out where to post a question, I point them in the right direction BECAUSE a question asked in the right forum, is more likely to get an answer.

string strUrl = "http://www.abc.com/a.aspx";
Uri url = new Uri(strUrl);
string strFinal = url.ToString();
WebRequest objWebReq = WebRequest.Create(strFinal);
WebResponse objWebRes = objWebReq.GetResponse();
Stream objStream = objWebRes.GetResponseStream();
StreamReader objStreamReader = new StreamReader(objStream);
string strHTML = objStreamReader.ReadToEnd();

Hi Aman,
Thank you for your help.
I have tried your solution, but I'm still getting "Unable to read data from the transport connection" at this line objStreamReader.ReadToEnd
The URI is ok though, please advice...
|
|
|
|
|

WebClient class wraps all these nicely. So you don't have to use WebRequest or WebResponse explicitly unless it is really required.
