Hi..
I developed one website in which i used asp.net default validation control for validaton. They well work on localhost but they not worked whwn i upload them on live server.
why this happens?
actually they worked on one page "register.aspx" on live server, but not other pages on live server.

maybe some applications insstalled on your pc that uses from some dll files in your pc.

We Can Do Anything, If We Want It

I have added dll named and created the object.Here is the code:

Imports Outlook = Microsoft.Office.Interop.Outlook

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Try
Dim app As Outlook.Application = New Outlook.ApplicationClass()
Dim NS As Outlook.NameSpace = app.GetNamespace("MAPI")
Dim inboxFld As Outlook.MAPIFolder = NS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox)
For Each t As Outlook.MailItem In inboxFld.Items
Try
Response.Write(t.Subject)
Catch ex As Exception
End Try
Next
Catch ex As Exception
End Try
End Sub

If any undelivery mail is there in the Indox it thorws an exception saying:

Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.Office.Interop.Outlook.MailItem'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{00063034-0000-0000-C000-000000000046}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

Can anyone tell me how can I handle this as I need to read all the mails and seperate the delivery mails and undelivery mails.

Also how can I make the reading from date to date.I mean I need to read only mail a week back but not all.

Thanks in advance...

Please help count user visit in website Frown | :(

I think this will help you

<br />
protected void Application_Start(Object sender, EventArgs e) <br />
{<br />
<br />
// Retrieve the count from the database <br />
<br />
Application[RUNNINGCOUNT] = Visit.GetTotalCount(); <br />
<br />
}<br />
<br />
protected void Session_Start(Object sender, EventArgs e)<br />
<br />
{ <br />
<br />
Application[TOTALUSERS] = Convert.ToInt32(Application[TOTALUSERS]) + 1; <br />
<br />
// If you need a running count should declare another Application variable<br />
<br />
Application[RUNNINGCOUNT] = Convert.ToInt32(Application[RUNNINGCOUNT]) + 1; <br />
<br />
 if((int)(Application[TOTALUSERS]) >= Convert.ToInt32((ConfigurationSettings.AppSettings["MAX"])) )<br />
<br />
 {<br />
<br />
 Visit.Count((int) Application[TOTALUSERS]); <br />
<br />
// // Initialize the count again <br />
<br />
 Application[TOTALUSERS] = 0; <br />
<br />
}<br />

I have created one very simple web service say helloWorld which accepts one string and concate with "Hello" word.and its located in my localhost only.

Here is some behavour with it.
(1) i can access this web service synchronously without an issue.like

Dim webServ As New localhost.Service
Response.Write(webServ.HelloWorld(TextBox1.Text))

(2)now i am trying to call it asynchronously. Like this

Dim ar As IAsyncResult = webServ.BeginHelloWorld(TextBox1.Text, Nothing, Nothing)
While (True)
If ar.IsCompleted Then
Exit While
End If
End While
Response.Write(webServ.EndHelloWorld(ar))

(3) Now this code is executes file on the other machine i have ,but is not been able to call on my machine.I am receiving following error on the execution of above code.

The attempted operation is not supported for the type of object referenced

" at System.Net.Sockets.Socket.get_ConnectEx()
at System.Net.Sockets.Socket.BeginConnectEx(EndPoint remoteEP, Boolean flowContext, AsyncCallback callback, Object state)
at System.Net.Sockets.Socket.UnsafeBeginConnect(EndPoint remoteEP, AsyncCallback callback, Object state)
at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Int32 timeout, Exception& exception)"

System.Net.WebException = {"Unable to connect to the remote server"}

(4) i done long googling but could'nt get the exact solution.

(5) I also tried by removing my framework 2.0 ,visual studio 2005 and IIS as well.

(6) Some blogs says its network error,i also tried by repairing my network drivers but problem persists as it is.

(7) Some blogs also suggested that i do have third party network protocols and that may causes the blocking of Http Request for async. call.then i also removed all such softwares from my machine,but the same result.

I am very frustated with this issue and hampered my development.
Any kind of help is most welcomed.
lots thanks in advance.

Hai to all,
Till now i have used the function for converting the string values to integer as

Integer.parse(txtnumber.text)
and also used
Int32.parse(txtnumber.text)

And now it is giving an error like
"Input string was not in a correct Format".
What might be the reason for it is working for some forms and not for others.CAn anyone tell me in what cases it will give this type of error??

kissy

it gives the error only when txtnumber.text contains characters other than digit.
before converting string value to integer u need to validate the input string.... by say regular exp...
Regex reNo = new Regex(@"^[0-9]{*}$");
if (reNo.Match(txtnumber.text).Success == false)
{
//display err. msg. "invalid data"
}
else
{
//Convert to integer
Int32.parse(txtnumber.text)
}

///this way it will not give run time err.

DEar Vaibhav,
Thanks for ur reply,Ur suggestion is good,but even when i am entering digits then only it is giving error.
I have more than 10 textboxes for entering digits into textboxes and need to convert them into integer values for the database in my webform.
But it is not possible for giving RegExp for all these textboxes in a single form??Isn't it??
I am using VB in my aps.net.
What to do???
Actully here i have kept all the textboxes in a table,Is it makes any difference???If the textbox is not in the table(in open) then it is not giveng any error???

kissy

Then in this case u can use Regular exp. validators for each textbox..
and also pls update the reg. exp. to "^[0-9]*$"..
and about placing things in table would not make any difference...

if the text of your textbox(txtnumber) has an empty string it would give the above error, because becomes unable to parse it into integer.

Hai,
Thaks for ur reply.But my doubt is Even i am entering some value into thetextbox it is giving blank when i am parsing the data.
How it is happening.Means it is nothin is coming into the textbox while conversion.
Can u give me some idea.

kissy

can u pls show me ur code...
so that i can help u out.

Hai,
Try
Dim str As String = txtseedno.Text
Dim dtrs As Integer = Convert.ToInt32(str)
Response.Write(dtrs)
Response.End()
Catch ex As Exception
Response.Write(ex.Message)
End Try
Also i have tried with
integer.parse(str)
But it is giving error because it is having blank value.I have taken this textbox in a table.
and simply i am showin on button click event

kissy

hey pls send me ur email id ...so that i can send u sample project..which works..k

Try this,

Dim str As String=txtseedno.Text
Dim dtrs As Integer=0

If str.Length > 0 Then
dtrs=Integer.Parse(str)
End If
response.write(dtrs)

but, your txtseedno (textbox) should be validate thorough regular expression validator.
