I am developing website in Asp.net 2.0 and planning to implement Ajax.
Can any one please suggest me which is best to use either
Jquery (or) Ajax control Toolkit..
I appreciate if you could give the reply soon...

The control toolkit is excellent for morons. It basically does all hte work for you, so long as you want what it does. JQuery is an excellent library, but it doesn't give you the sort of prebuilt controls that ASP.NET AJAX does.

Use ajax toolkit. Its very easy to use with VS.net.

I have to add the facilities of adding water mark on video files.
I am developing my application in c#.
any body help me for the same.
Thanks In advance.

|

Don't cross post. ASP.NET can't watermark a video, so asking in the C# forum, as you have done, is the right thing to do.

Dear Experts,
Do you have any idea encrypted string in Java and decrypt in asp.net using the same AES algorithm?
|
|
|
|
|
Sure - if it's the same algorithm, that should work just fine.
Help me is a stupid subject line. Everyone here wants help.

I am trying to decrypt the string in asp.net which is encryted in java.I am able to do it till some extent but its not completely decrypting.
Here i am putting the code of both (Decryption through ASP.NET and Encryption through Java)
private String Encrypt() /// Done in Java return encryted string
{
String hexString="";
String msg="Sample Input Text";
SecretKeySpec skeySpec ="GbxDwxcjvjtpi0+lQuyfHg=="; // Autogennerate Key
try
{
Cipher cipher = Cipher.getInstance("AES");
cipher.init(Cipher.ENCRYPT_MODE, skeySpec);
byte[] encrypted = cipher.doFinal(msg.getBytes());
hexString=asHex(encrypted);
}
catch(Exception e)
{
System.out.println("Error in Encrypt"+e);
}
return hexString;
}
private void DecryptFunction() // Done in Asp.net
{
try
{
string strEncrypt = "fc8caff8581f9a3920b788490c3569ffb345e54c7f72a73ddb76256ff81fbfd6";// Encrypt string
string AutoKey= "GbxDwxcjvjtpi0+lQuyfHg==";
TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider();
tdes.Key = Encoding.UTF8.GetBytes(AutoKey= );
tdes.Mode = CipherMode.ECB;
tdes.Padding = PaddingMode.PKCS7;
ICryptoTransform crypt = tdes.CreateDecryptor();
byte[] cipher = FromHex(strEncrypt);
byte[] plain = crypt.TransformFinalBlock(cipher, 0, cipher.Length); // Here Error showing
Response.Write("Decryped string : " + System.Text.Encoding.UTF8.GetString(plain) + "<br/><br/><br/><br/>");
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
}
Here decryt function should be return decrypt string means Sample Input Text but its showing Bad Data error.
I give error screen shot also.

Follow the below steps: I am posting with small exmaple
A.Code in sender page of uery string
1.string strID = "A0123456789";
2. Response.Redirect("../Search/DocumentSearch.aspx?ID=" + Encrypt(strID));
3.public string Encrypt(string strValue)
{
string encryptedResult = String.Empty;
string passPhrase = "Pas5pr@se";
string saltValue = "s@1tValue";
string hashAlgorithm = "SHA1";
int passwordIterations = 2;
string initVector = "@1B2c3D4e5F6g7H8";
int keySize = 256;
byte[] initVectorBytes;
initVectorBytes = Encoding.ASCII.GetBytes(initVector);
byte[] saltValueBytes;
saltValueBytes = Encoding.ASCII.GetBytes(saltValue);
byte[] plainTextBytes;
plainTextBytes = Encoding.UTF8.GetBytes(strValue);
PasswordDeriveBytes password;
password = new PasswordDeriveBytes(passPhrase, saltValueBytes, hashAlgorithm, passwordIterations);
byte[] keyBytes;
keyBytes = password.GetBytes((keySize / 8));
RijndaelManaged symmetricKey;
symmetricKey = new RijndaelManaged();
symmetricKey.Mode = CipherMode.CBC;
ICryptoTransform encryptor;
encryptor = symmetricKey.CreateEncryptor(keyBytes, initVectorBytes);
MemoryStream memoryStream;
memoryStream = new MemoryStream();
CryptoStream cryptoStream;
cryptoStream = new CryptoStream(memoryStream, encryptor, CryptoStreamMode.Write);
cryptoStream.Write(plainTextBytes, 0, plainTextBytes.Length);
cryptoStream.FlushFinalBlock();
byte[] cipherTextBytes;
cipherTextBytes = memoryStream.ToArray();
memoryStream.Close();
cryptoStream.Close();
string cipherText;
cipherText = Convert.ToBase64String(cipherTextBytes);
return cipherText;
}
B. Code in receiver page of querystring
1.string strID = Request.QueryString["ID"].ToString();
string plainValue= Decrypt(strID);
2. public string Decrypt(string encryptedResult)
{
string passPhrase = "Pas5pr@se";
string saltValue = "s@1tValue";
string hashAlgorithm = "SHA1";
int passwordIterations = 2;
string initVector = "@1B2c3D4e5F6g7H8";
int keySize = 256;
byte[] initVectorBytes;
initVectorBytes = Encoding.ASCII.GetBytes(initVector);
byte[] saltValueBytes;
saltValueBytes = Encoding.ASCII.GetBytes(saltValue);
byte[] cipherTextBytes = new byte[encryptedResult.Length] ;
cipherTextBytes = Convert.FromBase64String(encryptedResult);
PasswordDeriveBytes password;
password = new PasswordDeriveBytes(passPhrase, saltValueBytes, hashAlgorithm, passwordIterations);
byte[] keyBytes;
keyBytes = password.GetBytes((keySize / 8));
RijndaelManaged symmetricKey;
symmetricKey = new RijndaelManaged();
symmetricKey.Mode = CipherMode.CBC;
ICryptoTransform decryptor;
decryptor = symmetricKey.CreateDecryptor(keyBytes, initVectorBytes);
MemoryStream memoryStream;
memoryStream = new MemoryStream(cipherTextBytes);
CryptoStream cryptoStream;
cryptoStream = new CryptoStream(memoryStream, decryptor, CryptoStreamMode.Read);
byte[] plainTextBytes= new byte [encryptedResult.Length ] ;
//object plainTextBytes;
int decryptedByteCount;
decryptedByteCount = cryptoStream.Read(plainTextBytes, 0, plainTextBytes.Length);
memoryStream.Close();
cryptoStream.Close();
string plainText;
plainText = Encoding.UTF8.GetString(plainTextBytes, 0, decryptedByteCount);
return plainText;
}
Cheers!

instead of encrypt the query string you have to use the urlrewriting.
so that you can get exact url.

hi..
i have a DataTable dt width data
Id Price
1 250
2 200
3 300
DataSet ds = new DataSet();
ds.Tables.Add(dt);
XmlDataDocument x = new XmlDataDocument(ds);
and a procedure in sql server 2005
create procedure Sproc_Select_Xml(@x xml)
AS
BEGIN
DECLARE @data TABLE(Id bigint,Price numeric)
INSERT INTO @data(Id,Price)
SELECT xmlVals.rowvals.query('Id').value('.','bigint'),
xmlVals.rowvals.query('Price').value('.','numeric')
FROM @x.nodes('/ds/dt') as xmlVals(rowvals)
SELECT * FROM @data
END
when i pass xml document to proc
i get the error
System.ArgumentException: No mapping exists from object type System.Xml.XmlDataDocument to a known managed provider native type.

The error means what it says. Don't pass in the XML document, pass in the XML.

I have a gridview in an updatepanel (I need this for a partial page postback on sort and paging). I also have a buttonField in my gridview and a panel(div) outside the updatepanel.
How do I hide and show the panel when the buttonField is clicked? My code works without the updatepanel but does not work with the updatepanel. I'm obviously missing something. Any help would be greatly appreciated.
My code structure below:
<asp:UpdatePanel ID="updPnlEmployee" runat="server">
<ContentTemplate>
<asp:GridView ID="grdVWEmployee" runat="server" AllowPaging="True" AllowSorting="True" PageSize="50" AutoGenerateColumns="False" DataKeyNames="Employee_ID" DataSourceID="odsEmployee" OnRowDataBound="grdVWEmployee_RowDataBound" OnRowCommand="grdVWEmployee_RowCommand">
<Columns>
<asp:BoundField DataField="First_Name" HeaderText="First Name" SortExpression="First_Name"/>
<asp:BoundField DataField="Last_Name" HeaderText="Last Name" SortExpression="Last_Name"/>
<asp:ButtonField Text="Eligibility" CommandName="Eligibility" CausesValidation="false"/>
</Columns>
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
<asp:Panel ID="pnlGrid" runat="server" CssClass="detail" width="500px" style="display:none">
</asp:Panel>
CODE BEHIND:
protected void grdVWEmployee_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Eligibility")
{
this.pnlGrid.Visible = true;
}
}
