Thats wot I want to know wot value u r assigning to Months column.
|
|
|
|
|
I assign the return data from sql statement which is string (because when I extract MONTHNAME from date it would return a string).
So there should not be System.Byte[] in the cell of the gridview.

TextBox1.Text= Convert.ToString(oWS.Cells.get_Item(1,1));
}
But whenever i run my application it shows exception as follws ....
------------------------------------------------------------------------------------------------
Access is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Access is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via , the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET write access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

how can i remove this problem?

<identity impersonation ="true"/>

Hi all,
i want session variables set in an asp page onto my ASP.NET page. IS it possible?
I have heared that it can be done by using hidden fields given in this article
http://www.eggheadcafe.com/articles/20021207.asp[^]
but i m using a menubar for navigation and hence i am not submitting any forms.
Is there any alternative..

You can share session between asp and asp.net. Check this[^] to get more information on it.

Hi all,

Here is my code
Sub SendMail()
Dim msg As New MailMessage()
Dim attach_file1 As String = String.Empty
Dim strfilename As String = String.Empty
Dim strpath As String = Request.ApplicationPath & "/" & "Attachments" & "/"
strfilename = Path.GetFileName(UploadCV.PostedFile.FileName)
UploadCV.PostedFile.SaveAs(Server.MapPath(strpath & strfilename))
Dim attach As New Attachment(Server.MapPath(strpath & strfilename))
msg.Attachments.Add(attach)
attach_file1 = strfilename
Dim smtpclnt As New SmtpClient()
Dim ds1 As New DataSet()
ds1 = CType(Session("Dataset"), DataSet)
msg.Subject = "You have successfully applied for the post of " & ds1.Tables(0).Rows(0).Item(2).ToString()
msg.Body = "Hi all"
'msg.To.Add(ds1.Tables(0).Rows(0).Item(9))
msg.To.Add("somemail@gmail.com")
msg.From = New MailAddress(Session("emailid").ToString())
smtpclnt.Send(msg)
If attach_file1 <> "" Then
File.Delete(Server.MapPath(strpath & strfilename))
End If
End Sub

Create a property and put it in session.
|
|
|
|
|
|
Session("mystring")=some value
It can be used any where in the application. Try this

Please read the forum guidelines. You have started several threads in which the message title has absolutely no meaning. Also, asking for the code is considered rude. You are expected to at least try programming and if you get stuck we will help.
