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.

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

Set() won't work because the whole collection is read only. Your best bet is rewrite the path.

Hi,

I am using an ActiveX control in a web page, when a button is clicked the control is executed in java script code, Before executing the control, the system is displaying a prompt message that:

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

Yes, get the user to disable them. This is a security feature, you can't just turn it off remotely

access server controls using javascript in web user controls

21-Mar-08 19:57

I doubt it. You could do some javascript to alternate between a textbox and a dropdownlist, but I don't think a HTML drop list is ever editable.

Re: access server controls using javascript in web user controls

Your first port of call ( apart from google ) should be to look at the actual HTML being generated. ASP.NET generates unique client side names. That means the server side name is not it.

On the server side, txtActualCost has a property called ClientID. Emit some script that stores this value for the client side and use that.

Please read what I told you. What you're doing, won't work, for the reason I just explained. Please do what I suggested - look at the HTML and you'll see what it's called on the client. The nasty hack is to copy that value, the right way is to use the ClientID property to write out the right string into your javascript.

As CG suggested, use ClientId. If your server control is in a user control, ASP.NET prefixes the user control's id with the control id. So your getElementById('ControlName') won't work. Use ClientId instead.

var controlId = '<% ControlId.ClientId %>';
var controlObject = document.getElementById(controlId);

As I told, use ClientId instead. Appending container id with control's id is a ASP.NET mechanism to keep control id unique throughout the page.

When I began the programming for http://www.sceptermarketingtechnologies.com, I quickly noticed that Asp.net does not support the MessageBox class that I was familiar with in windows forms.

Since Asp.net runs on the server it doesn't have access to produce a modal dialog box on the client. However, by using a scripting language that runs in the clients browser a similar construct is available. In javascript the window.alert() function will produce a modal dialog similar to what you would expect from MessageBox in windows forms.

So, I decided to create a static class MessageBox with a static method Show(), which will give you the ablility to to still use the syntax MessageBox.Show("Your Message"); and then convert it into the javascript window.alert("Your Message"); and add the script to the end of the current response stream.

I've written a how to on my blog at: http://sceptermt.blogspot.com/2008/02/how-to-create-message-box-class-in-c.html that shows the source code that I used in C# for my web application and details on how it works.

You could also write overloads for the static show() method to allow the class to do a javascript confirm() or a prompt(). I haven't needed that functionality yet so I've just kept it simple.
