If you want to click on a button on pressing the enter key,the set the button as Defaultbutton of the page.

in asp.net how to create a dll file
|
|
|
|
|
Put the proper heading in subject tag.
For creating the dll,you need to create the classlibrary type project then build it.and you will get the dll in debug folder.Then add this dll as referance where you want.
Cheers!!

Just get the Row data in a GridViewRow Class Object and access the details from there !!

Create session variables each for every right (like bit 1 for authorized and 0 for not). After login check for those in database and according to that set the session variables.
tejesh123 wrote: Authorization is required at the menus
Check for those variables while loading menu, if true then show link and otherwise.
tejesh123 wrote: also it must able protect the user from directly opening the pages by typing in the url.
At !PostBack, check if session variables have values or not and at not, redirect to Home Page.
note: create all variables in one .cs page and render that whole page as Session (eg. SessionVariables sp = new SessionVariables(); sp = session["SessionVariables"]; where session["SessionVariables"] is created in previous page like session["SessionVariables"] = sp;)
Hope this helps!!!

Still confused..
After i retrive the resources from sql server in string array,i need to copy it in session then i need to check whether the resources matches the arrtribute tag for the page..if yes provide the access if no otherwise
but how do i at menu level(Navigation) & if any alternate mechanism at the page level
Please provide a sample code
|
|
|
|
|
Instead using .NET server control for menu, use JavaScript for menu creation. It will ease checking an also provide better design with explicit css than in-built tamplets.

You can do it just simple way . Create a Default page that will display the Unauthorized User message. When you click on the link to open the page that time just simple check the roll of user, if the roles permit to access that page , navigate to that page other wise redirect to unauthorized access page. On unauthorized access page give a link to user back to the home page.
<code>OnAdminLinkClicked()
{
if(Session["CurrentUserRole"].equals("Admin"))
{
Response.redirect("Admin.aspx");
}
else
{
Response.Redirect("Unauthorized.aspx)
}
}</code>
Note: Given code is just a dummy example, not compiled and checked !!!

thx for the reply
Well there may be more than 100+ users and more than 100+ access right and which are defined at the group level and some special at personal level..
Is it going to be optimistic solution for my problem..
Any custom methods which can be used across all the pages on the website.
Also please give a solution for menu security w/o using role based security provided by asp.net

Hi all,
Is there any way to check whether Email exists not syntax wise.For eg:aaaaaaaaaaa@bbbbb.com. though it has valid syntax it doesn't exist in real.How to check this using asp.net code.Please help me.
Thanks.

No, there isn't, not short of sending an email and seeing if it bounces, but that's not 100%, and it's user intrusive.

There is no 100% guranteed way but you can check mx records. Try the following code it may give an idea.
public class MailValidator
{
private bool mResult = false;
public bool Result
{
get { return mResult; }
set { mResult = value; }
}
private string mError = "";
public string Error
{
get { return mError; }
set { mError = value; }
}
private string mMailAddress = "";
public string MailAddress
{
get { return mMailAddress; }
set { mMailAddress = value; }
}
public MailValidator(string mailAddress)
{
mMailAddress = mailAddress;
}
public bool MailExists()
{
string domainName = mMailAddress.Substring(mMailAddress.IndexOf("@") + 1);
foreach (string str in Mx.GetMXRecords(domainName))
{
TcpClient insTcpClient=null;
try
{
//MessageBox.Show(str);
insTcpClient = new TcpClient(str, 25);
NetworkStream ns = insTcpClient.GetStream();
byte[] recievedMessage = new byte[insTcpClient.ReceiveBufferSize];
ns.Read(recievedMessage, 0, insTcpClient.ReceiveBufferSize);
//MessageBox.Show(Encoding.ASCII.GetString(recievedMessage));
string messageToSend = "HELO\r\n";
byte[] buffer = System.Text.Encoding.GetEncoding(1254).GetBytes(messageToSend);
ns.Write(buffer, 0, buffer.Length);
recievedMessage = new byte[insTcpClient.ReceiveBufferSize];
ns.Read(recievedMessage, 0, insTcpClient.ReceiveBufferSize);
//MessageBox.Show(Encoding.ASCII.GetString(recievedMessage));
messageToSend = "MAIL FROM:<deneme@" + domainName + ">\r\n";
buffer = System.Text.Encoding.GetEncoding(1254).GetBytes(messageToSend);
ns.Write(buffer, 0, buffer.Length);
recievedMessage = new byte[insTcpClient.ReceiveBufferSize];
ns.Read(recievedMessage, 0, insTcpClient.ReceiveBufferSize);
//MessageBox.Show(Encoding.ASCII.GetString(recievedMessage));
messageToSend = "RCPT TO:<" + mMailAddress + ">\r\n";
buffer = System.Text.Encoding.GetEncoding(1254).GetBytes(messageToSend);
ns.Write(buffer, 0, buffer.Length);
recievedMessage = new byte[insTcpClient.ReceiveBufferSize];
ns.Read(recievedMessage, 0, insTcpClient.ReceiveBufferSize);
//MessageBox.Show(Encoding.ASCII.GetString(recievedMessage));
if (Encoding.ASCII.GetString(recievedMessage).StartsWith("250"))
{
mResult = true;
}
insTcpClient.GetStream().Close();
insTcpClient.Close();
}
catch (Exception ex)
{

Check this site out ...
http://www.webservicex.net/WCF/ServiceDetails.aspx?SID=22[^]
I played around with it and it seemed to work very well. I don't know how they validate the email address, but it seems to work.
I've also played around with their stock-quote webservice, which works very nicely.
Give it a shot.

DiseaseGrid.DataBind(); <br />
DiseaseGrid.Width = 100;<br />
DiseaseGrid.Height = 50;<br />
DiseaseGrid.GridLines = GridLines.Both;<br />
DiseaseGrid.CellPadding = 0;<br />
DiseaseGrid.HeaderStyle.BackColor = System.Drawing.Color.Pink; <br />
<br />
foreach (Master_ref_disease masterDisease in Master_reference_disease.result()
{<br />
BoundField c = new BoundField();<br />
c.HeaderText = masterDisease.D_ID;<br />
DiseaseGrid.Columns.Add(c); <br />
}<br />
PlaceHolder1.Controls.Add(DiseaseGrid);<br />
DiseaseGrid.DataBind(); <br />
