alert(Text1.value)}

This doesn't work for two reasons:

1 - Text1 exists on the server, not the client
2 - If Text1 is a server side control, the framework generates it's own Id for the client.

This will work:

function getlabel()
{

var controlId = '<%=Text1.ClientID%>';

var control = document.getElementByID(controlID);

if (control)
{
alert(control.value);
}

Hi all
I am working on asp.net application where i need to upload a file. code what i wrote is

Private Sub CmdUpload_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CmdUpload.Click
If File1.PostedFile Is Nothing Then
Me.lblResult.Text = "No File Selected to Upload."
Exit Sub
End If

'Retrieve file information and upload to server.
Dim strName As String
strName = System.IO.Path.GetFileName(File1.PostedFile.FileName)

Try
File1.PostedFile.SaveAs(Server.MapPath("Resumes/" & strName))
Me.lblResult.Text = """" + strName + """ was uploaded successfully."
Catch ex As Exception
Me.lblResult.Text = "An Error Occured While Uploading File."
End Try
End Sub

Every thing is fine but its showing a error after the upload button is clicked " No access to write into the server " right now i am using my local system as server and i have clicked on all access permission "Write" . but getting the same error.
Pl help
Regards

Try adding a line like this:

<identity impersonate="true" username="xxx" password="yyy" />

inside the system.web block of your web.config file, replacing xxx/yyy with your admin login to your computer. <u>Make sure you take this line out when uploading to the deployment server!</u> (And get the administrators of that to enable the appropriate write permissions for you there...)

Works for me - like you I could not, for the life of me, grant asp.net write permissions otherwise...

cheers

Hashed Password

Hi,
My asp.net 1.1 website security system depend on hashing passwords.So it is impossible to recover the password.I think when the user forgot his password the web application should generate a password for him automatically and send it to his email so he can log again using his new password.Could any one tell me how could I make the web application generate the password automatically?Is it safe to send it by email to the user?

I am too late but i will never give up

Yes, email is fine, it's certainly your most secure option. How you generate it is up to you, you could send part of a GUID, or have a table full of words and pull three out at random, or whatever you like.

Do you mean that I should add a new column of type GUID in the users table...I think it is a great idea because the passwords I sent to them will differ from each other.

Thank you for these great ideas.

It is better to send email to that person.
Make forgotpassword link.
On this page give a textbox so that user enters his email address.
Send him his newly generated password by email.
Update his password in your DB table.

If any quieries then please ask me.

Yes.

You could use brute force to find a password that gives the same hash code, but there is no guarantee that it's the same as the original password.

Yes, that is what you normally would do when the passwords are hashed.

TheEagle wrote:

Pick some characters by random from a string with suitable characters. I exclude characters like "Il10oO" when generating passwords.

TheEagle wrote:

No, it's not safe. The email is sent unencrypted over the net, and it travels through mail servers that might be possible to hack into.

It might be safe enough for your purposes, though.

Thing is, what's a more secure option ?

Do you mean each time picking characters by random from the same string?Doesn't this mean that some passwords will be the same?

So what ? Do you take steps to ensure that no two passwords are the same now ? How does it matter ? It's not like users enter a password alone, they need the username as well, right ?

TheEagle1-Jun-07 4:07

You are right.So I don't need to add a cloumn just a new GUID or a string to pick characters from it by random.Thank you very much and all experts who helped me in this thread. Smile | :)

If you have a string with 30 characters and pick four characters for the password, there is a 0.00012% risk that two given passwords will be the same.

If you generate a large number of passwords, of course some will be the same, but that is not a problem. Do you have a ATM card with a four digit PIN code? Have you ever stopped to think that there are thousands of other people who have the exact same PIN code as you have? Smile | :)
