Hi all,
I am creating my database using the server explorer in VS 2005, I defined almost all tabes and relations I need except that I don't know how to impose a 'unique' constraint on a specific column called "username".
Any idea on how to do this using Server explorer?
Thanks

This isn't the right forum for SQL questions. You should use the SQL forum in future.
Open your table in design mode. From the 'Table Designer' menu, select Indexes/Keys. Create a new index and set its 'Is Unique' property to True.

You could have a number of of web forms that inherit from the same code-behind class.
I can't imagine why you would want to create an instance of a web form code-behind class on its own though. Maybe you can further clarify what you want to achieve.

thanks for replying. The idea is that i need to access a control inside that form to make some modifications in that user control instead of creating many user controls with some minor changes.
I hope that i made the idea clearer. Thanks

This sounds like a horrible idea. I would strongly discourage it.
What kind of minor changes are you talking about? If they are cosmetic changes, you could consider writing a templated user control where the presentation can be modified for each instance.

mmmm
this sounds like a good idea, thanks for your support

Your web form is a class already. You can inherit from it, create an instance of it (making an object of it) and so on.
But, why would you want to create one outside of the context that ASP.NET creates it for you in the first place?

Hi All,
I want to add a User Control at runtime. Like the user control should be added when a particular button on the another user control is clicked. And if not clicked it shouldnt be displayed.
And maintain the view state of the controls which are inside the User Control. Can anybody please help me in this.
Thanks,
Aleem Mohammad.

In order to dynamically add a user control (or any control for that matter) to the page you need to add it to an appropriate controls collection. Each control has a controls collection as does the page.
So, create your user control then add it to the controls collection you want (probably the page, or possibly the controls collection of the other user control)
Remember dyanmically created controls will not be recreated at each postback. It is your responsibility to recreate the control on each post back. So long as you create the control during the page load event then you will get the viewstate along with it. (Although, maybe not in during the Page Load event itself).

How can I customize the layout of my divs during runtime? I need to Know how to change the location of the divs in the site if it is possible. Thanks
|
|
|
|
|
Do you mean dragging the div's ? Use javascript to do that. There is a project in codeplex named "DropThings". Look at it's code.
|
|
|
|

10xs for your reply. My real problem is to create a GUI where a user can change the location of the divs from a webpage that allows to do so. if you know how please post again.

Hi,
I wrote this code for sending mail but the error that the ip is refused is appeared,
what's the problem?
Dim message As New MailMessage()
Dim f1 As String = String.Empty
If FileUpload1.HasFile Then
f1 = FileUpload1.FileName
FileUpload1.SaveAs(Server.MapPath("Attach/" + file1))
Dim attach As New Attachment(Server.MapPath("Attach/" + file1))
message.Attachments.Add(attach)
End If
message.Body = txtBody.Text
Dim mailAdrs As New MailAddress(txtEmailSender.Text, txtSender.Text)
message.From = mailAdrs
message.Subject = txtSubject.Text
Dim con As New SqlConnection()
con.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings("DrMasanConnectionString").ConnectionString
Dim com As New SqlCommand()
com.CommandText = "Select Email From [User]"
com.Connection = con
con.Open()
Dim reader As SqlDataReader = com.ExecuteReader()
While reader.Read()
message.To.Add(reader("Email"))
End While
Dim smtpC As New SmtpClient()
smtpC.Host = "drmasan.com"
smtpC.Send(message)
Best wishes

Looks like the host name provided here is refusing connection. Have checked with the provider ?

OT : AFAIK, there is a limit in the number of recipients which can be specified at the TO address. So if you have more number of users than the allowed limit, it will throw error. Also there is no need to save the file for attaching with mail, you can attach a file from stream.

Hi,
I have an httpmodule which am using to modify the value of my querystring parameter.
What i did was to encrypt the value of the querystring parameter, am decrypting the parameter inside the BeginRequest event so my code behinde will have access to the plaintext.
the issue is when retrieve the parameter into a NameValueCollection and try to use the Set method to update the parameter value i get this error. System.NotSupportedException: Collection is read-only.
but i can't access the IsReadOnly property of the class. how do i update the decrypted parameter value to the querystring so i can have the plaintext in my code behind.
Thanks in advance

AFAIK, query string collection is read only. So you can't assign anything to there. Instead ,you can rewrite the path with the new values required. Use Context.RewritePath
|
|
|
|
|
wat happens to the NameValueeCollection Set Method, wat is d use?
|
|
|
|
|
Set() won't work because the whole collection is read only. Your best bet is rewrite the path.

An activeX control on this page might be unsafe to interact with other parts of the page, Do you want to allow this interaction.
is there any way to disable such prompts.
Thanks in Advance
