First of all use the CODE tag whenever you are posting code. your current code is unreadable.
ok so You are not closing the existing connection. close the connection as soon as you finished communicating.
i.e. after using the reader/datatable/dataset, insert/delete/update query.
if you are closing the connection and then also you are getting the error, due to very busy website. change the MAX POOL SIZE in the connection string.
connectionString="Server=XXX;Database=XXX;User Id=XXX;password=XXX;connection timeout=0;Max Pool Size = 100;Pooling = True"

Thanks for your reply
I have corrected CODE tag
I know that I am not closing the existing connection, but I do not know which, that's the problem
Thanks Anders

In your code
return SqlHelper.ExecuteDataset(ObjDBAbstract.GetConnectionString(), "users_list", Guid.Empty);
in the ExecuteDataset try makng use of the USING statement, this will automaically close and dispose of your connection

Hi,
I have a GridView which is teamed up with a DetailsView and they work fine. I've added New, Delete and Edit buttons to the DetailsView and that all works fine too.
The problem I have is what to do if there are no rows in the GridView. The DetailsView shows nothing, not even the buttons so I can't simply add a new item from there.
I can create a new button which will open a new page to create a new item but this seems very clumsy and inelegant.
Can someone suggest a better way of doing this? Is it possible to force the display of the DetailsView rows including the buttons, even if the GridView is empty?
Thanks

Hi - I'm new to vb.net and stuck with a little problem....I can write the string out as raw data but want to write it out so that it makes sense as "english" (formatted list I suppose). Can anybody help please? Here is my working code:
<%@ Page Language="VB" %>
<%@ Import Namespace="System.Net" %>
<%@ Import Namespace="System.IO" %>
<%@ Import Namespace="System.Xml" %>
<%@ Import Namespace="System.Xml.Xsl" %>
<script runat="server">
Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Dim strDataToPost As String
Dim myWebRequest As WebRequest
Dim myRequestStream As Stream
Dim myStreamWriter As StreamWriter
Dim myWebResponse As WebResponse
Dim myResponseStream As Stream
Dim myStreamReader As StreamReader
' Create a new WebRequest which targets that page with
' which we want to interact.
myWebRequest = WebRequest.Create( _
"http://test..co.uk/XmlService.asmx")
' Set the method to "POST" and the content type so the
' server knows to expect form data in the body of the
' request.
With myWebRequest
.Method = "POST"
.ContentType = "text/xml"
End With
' Here's the data I'll be sending. It's the same format
' you'd use in a querysting and you should URLEncode any
' data that may need it.
strDataToPost = "<RegionSearch>blah</RegionSearch>"
' Get a handle on the Stream of data we're sending to
' the remote server, connect a StreamWriter to it, and
' write our data to the Stream using the StreamWriter.
myRequestStream = myWebRequest.GetRequestStream()
myStreamWriter = New StreamWriter(myRequestStream)
myStreamWriter.Write(strDataToPost)
myStreamWriter.Flush()
myStreamWriter.Close()
myRequestStream.Close()
' Get the response from the remote server.
myWebResponse = myWebRequest.GetResponse()
' Get the server's response status?
' Just like when we sent the data, we'll get a reference
' to the response Stream, connect a StreamReader to the
' Stream and use the reader to actually read the reply.
myResponseStream = myWebResponse.GetResponseStream()
myStreamReader = New StreamReader(myResponseStream)
litResponseText.Text = myStreamReader.ReadToEnd()
myStreamReader.Close()
myResponseStream.Close()
' Close the WebResponse
myWebResponse.Close()
End Sub

I'm using this code to run process:
"...
_apppath = String.Concat(_apppath, "zvprtcfg_win32");
string _command = " Zan Image Printer(fax) print.html = ";
_command += strHtmlFileName;
try
{
Process _proc = new Process();
_proc.StartInfo.Arguments = _command;
_proc.StartInfo.FileName = _apppath;
if (_proc.Start())
{
int _i = 0;
do
{
_proc.WaitForExit(1000);
if (_proc.HasExited)
{
_bOk = true;
break;
}
} while (_proc.Responding && _i++ < 30);
if (!_bOk)
{
_proc.Kill();
}
}
}
catch (Exception eproc){}
..."
This works fine with my XP machine with IIS V5.1, but I can't make this work with Server 2003 and IIS V6.0.
In Server 2003, the process shows in the task manager, but it doesn't execute as I'm expecting.
ASPNET user run "zvprtcfg_win32" process on my machine and NETWORK SERVICE user run it on Server 2003.
Please give me some advice, solution...
Thanks in advance.

Hi,
I think the problem is the account "Network Service". This one will not have the rights to run your process as you expecting it. Try to figure out what rights for this user are missing (file, printer access etc.).
The network service is the default user for ASP.NET under Win2003 and IIS 6.0. Maybe you can figure out how to change the default use, so that ASP.NET is executed with other permissions.
Hope this helps you a bit.
Regards
Sebastian
P.S. Have a look at the event log of Windows, there you will find some information about critical operations etc, which where denied.

Thank you very much.
Everything you wrote I already know, but I totally forgot "P.S." part  . And there (at the Event log) was solution to my problem.
Thanks once more.
Regards,
Nina
My problem was:
The machine-default permission settings do not grant Local Activation permission for Internet Explorer to the user NT AUTHORITY\NETWORK SERVICE.

I captured the value of Id of the browser using Request.Querystring but the problem is the value caputered had "+" symbol which is not being shown. Its taking as a concatination.
How can i handle.
|
|
|
|
|
The querystring will convert + sign to white space character. You have to write code for track this.
|
|
|
|
|
You need to make sure the querystring is URL Encoded. I use the following function that i find useful
Public Function Encrypt_UrlEncode(ByVal textToEncrypt As String) As String
Try
Return System.Web.HttpUtility.UrlEncode(textToEncrypt, System.Text.Encoding.Default)
Catch ex As Exception
Throw ex
End Try
end function
In your code before you redirect do something like this
Dim queryString as string=Encrypt_UrlEncode(WhatEverStringYouWantToPassAsQueryString)
response.redirect("http://www.abc.com/RedirectPage.aspx?Q=" & queryString)
Good Luck

Hello,
I have a asp:listView control bound to a LinqDatasource, works fine.
In code behind (as a result of a buttonclick somewhere) i would like to get a dataitem from the datasource (or maybe the ListView) based on the Listviews SelectedIndex.
Tried to get it from listview.Items[listview.SelectedIndex], but the DataItem member is always null.
Any ideas?
Thanks in advance,
Antoon

Sub DGDoc_ItemCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles DGDoc.ItemCreated
Try
If e.Item.ItemType = ListItemType.Header Then
Dim DelLink As New LinkButton()
DelLink.Text = "Delete"
DelLink.Attributes.Add("runat", "server")
DelLink.Attributes.Add("id", "OnDelete")
DelLink.Attributes.Add("CommandName", "OnDelete")
DelLink.Attributes.Add("CommandArgument", "OnDelete")
'AddHandler DelLink.Command, AddressOf Dg_ItemDatabound
e.Item.Cells(8).Controls.Add(DelLink)
Dim EditLink As New LinkButton()
EditLink.Text = "Disp.Order/Edit"
EditLink.Attributes.Add("runat", "server")
EditLink.Attributes.Add("id", "OnEdit")
EditLink.Attributes.Add("CommandName", "OnEdit")
EditLink.Attributes.Add("CommandArgument", "OnEdit")
e.Item.Cells(7).Controls.Add(EditLink)

And clicking on to the link buttons created following code is to be executed
***
Sub Dg_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles DGDoc.ItemCommand

Are you looking for an FLV player[^]?

Well, that is way too little information to be useful. You have to post the code where the error occurs for the error message to be any helpful.
mr_muskurahat wrote: and 3.5 option also not coming in iis 5.1
There is no separate frameworks with version 3.0 or 3.5. You are still using framework 2.0. They are just additions.
Despite everything, the person most likely to be fooling you next is yourself.

ASP.NET is a different technology. Use CSS styles to define cursor.
