output cache problem : when any user control registered on a page page not cached

hi all
i have a strange problem with caching

very simple cache test page with fallowing code is not cached at all(browser/server whatever):

<%@ Register TagPrefix="uc1" TagName="NewHomePageModule" Src="~/Home/Module/NewHomePageModule.ascx" %><br />
<%@ Page language="c#"  %><br />
<%@ OutputCache Duration="60" VaryByParam="*" %><br />
		test form<br />
		<%=DateTime.Now%>

but when you remove this line :
<%@ Register TagPrefix="uc1" TagName="NewHomePageModule" Src="~/Home/Module/NewHomePageModule.ascx" %>

and i stay with :

<%@ Page language="c#"  %><br />
<%@ OutputCache Duration="60" VaryByParam="*" %><br />
		test form<br />
		<%=DateTime.Now%>

the caching starting to work correctly

the stranger thing is that happening only on production box (IIS6/ASP.Net 1.1) and on dev box (IIS5/ASP.NET 1.1) code work properly in both cases

i gave here example as simple as posssible, actually the whole caching framework we developed is not working on production machine

please help anybody has an idea or direction to trouble-shoot this
Thanks much anyway for your attention

Transactions are part of your data layer, they have nothing to do with the presentation layer. Or, do you mean something else ?

I meant , I had to insert the data in the two tables using single form and it is necessary that the data goes to both the tables else rollback occurs
Now I need to know how i have to implement this thing in ASP.
Thanks

If you're using asp, and not ASP.NET, you should ask in the web dev forum.

In both cases, the answer is the same. Your middle tier will handle the DB call, and the nature of your presentation layer is irrelevant. The best way to do it is a single stored proc, which handles the transaction.

What do you need to know ? You should only deploy a release version, a debug version is compiled to provide things you need debugging, that shouldn't be in the release version.

Encryption [modified]

Hi.

Does anyone has some experience with Encryption? I need to encrypt password user submits and store it in the database. And of course I need to decrypt it back and compare to user password when user signs in.

I created a test page and use System.Security.Cryptography.RijndaelManaged. On that page I encrypted string (passwrod) but not sure what to do next. I get Byte() back. How do I store it in the database? But most important how do I decrypt it back? When running encrypt and decrypt on the same page one after another and useing the same key it works with not problem. But if use decrypt separetely it throws me error.

Here's the error I get:
PKCS7 padding is invalid and cannot be removed.
My guess it has something to do with Key and/or IV. Does that mean I need to save Key as well? I'm lost.

Please help.

Thanks,

I got another solution

You must to create a new class sheet (name.CS)

Add these libraries

using System.Security.Cryptography;
using System.Text;
using System.IO;
using System.Xml;

I made these functions based in a codeproject encrypt solution

<br />
public string EncryptProcess(string password)<br />
{<br />
   string passwordEncryted = Encrypt(password, "&%#@?,:*");<br />
   return (passwordEncryted);<br />
}<br />
<br />
private static String Encrypt(String strText, String strEncrKey)<br />
{<br />
        byte[] bKey = new byte[8];<br />
        byte[] IV = { 0x12, 0x34, 0x56, 0x78, 0x90, 0xAB, 0xCD, 0xEF };<br />
<br />
        try<br />
        {<br />
            bKey = System.Text.Encoding.UTF8.GetBytes(strEncrKey.Substring(0, 8));<br />
            DESCryptoServiceProvider des = new DESCryptoServiceProvider();<br />
            Byte[] inputByteArray = Encoding.UTF8.GetBytes(strText);<br />
            MemoryStream ms = new MemoryStream();<br />
            CryptoStream cs = new CryptoStream(ms, des.CreateEncryptor(bKey, IV), CryptoStreamMode.Write);<br />
            cs.Write(inputByteArray, 0, inputByteArray.Length);<br />
            cs.FlushFinalBlock();<br />
            return Convert.ToBase64String(ms.ToArray());<br />
<br />
        }<br />
        catch (Exception ex)<br />
        {<br />
            return ex.Message;<br />
        }<br />
    }<br />
<br />

You must to invoice the first process
Ex: string pass = EncryptProcess("SGC"); //Uppercase
the answer is the string "2zhZqCYvfJc="

This is the Encrypt process, write me if works for you..
And i will write the Decrypt process Poke tongue | ;-P

Sorting gridview through javascript

ayeleteric23-Nov-06 2:22

ayeleteric

23-Nov-06 2:22

Hello,

I have a gridview of the columns, I am hiding the header of the gridview and creating my own header cells. (In fact I have a lot of columns and rowspan,columnspan.., but let simplify the problem)

My target is to sort the grid cicking on the header cells.

I add attributes to each one of the header cells as following
Dim cell11 As New TableCell
cell11.RowSpan = 2
cell11.Text = "Model Name"

cell11.Style.Add("text-decoration", "underline")
cell11.Style.Add("cursor", "hand")
cell11.Style.Add("color", "navy")

Now I have to add onclick attribute to the cell
cell11.Attributes.Add("OnClick", "SortGridView('Model Name')")

Here is my client side code:

var gridViewCtlId = '<%=GridView1.ClientID%>';

function getGridViewControl()
{
if (null == gridViewCtl)
{
gridViewCtl = document.getElementById(gridViewCtlId);
}
}

function SortGridView(colNm)
{
getGridViewControl();
if (null != gridViewCtl)
{
return gridViewCtl.sort[colNm,1];
}
return null;
}

What is the right code in javascript functions?
Thanx

document.getElementById('labelName').style.visibility='visible';

paid attention, if the label is located into contentplaceholder the code will be like that:

document.getElementById('ctl00_ContentPlaceHolder1_labelName').style.visibility='visible';

That is not possible. The server control only exists on the server, and the client script only exist in the browser.

If you want to hide an element with Javascript, use the display or visibility styles.
