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.

copying datarow to arraylist/array without using forloop........ [modified]

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;

Solution 2:

Create a temporary datatable and keep on updating the radio button status there.

TreeView control - dynamically bound to an XmlDocument? NavigationUrl

devvvy30-Jun-09 20:12

30-Jun-09 20:12

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.

How to do HTTP GET request

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.

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.

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

Dynamically Setting Images on an ASP net site

Reanalyse30-Jun-09 17:31

30-Jun-09 17:31

I have a large array of Imagebuttons on an ASPX page, that have the URL set depending upon the value of a variable
The value matches the name of the ImageButton as below. Rather than the convoluted code as below is there a way to somehow dynamically change the button - something like

ImageButton[mapflag].ImageUrl="warning.gif"

if (mapflag == "TV1_ANALOGUE") TV1_ANALOGUE.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV1_DTT") TV1_DTT.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV1_DTH") TV1_DTH.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV1_FM") TV1_FM.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV1_LINKING") TV1_LINKING.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV1_ISN") TV1_ISN.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV1_EXTEND") TV1_EXTEND.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV2_ANALOGUE") TV2_ANALOGUE.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV2_DTT") TV2_DTT.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV2_DTH") TV2_DTH.ImageUrl = "warning.gif"; <br />
if (mapflag == "TV2_FM") TV2_FM.ImageUrl = "warning.gif";
