Hi:
In my project for "Change Password Module" i am implementing following Logic:
1) User will Enter the OldPassword,NewPassword,Confirm Password then i am checking wether the Old Password is exists
2)If the OldPassword Exists I am setting Customvalidator =true and Maintaining session value=1
3)Now i am calling the session value in "Accept" buttonClick event in which i am cheking wether the session variable is one"
4)If the value is one, the Newly entered password will be updated otherwise Error message will be displayed.
The issue is session variable should not be used .Instead of session alternative method should be used.Can any one send me code for Change Password without using session variable.
I have mentioned the code below.
My code:
**************************Presentation Layer****************************
/// <summary>
/// Update The password
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void imgaccept_Click(object sender, ImageClickEventArgs e)
{
try
{
if (Page.IsValid == true)
{
if (Convert.ToString(Session["Validapassword"]) == "1")
{
Hashtable Has_PWDupdate = new Hashtable();
//Adding Values into Hashtable
Has_PWDupdate.Add("username",Session["UserName"].ToString());
Has_PWDupdate.Add("password", DAMS_Cls_EncryptDecrypt.Encrypt(txtNewpassword.Text));
ChangePWD.ChangePassword(Has_PWDupdate);
string strScript = "";
string strPath = "HomePage.aspx";
strScript = strScript + "<script language='javascript'>";
strScript = strScript + "alert('Your password successfully changed.');";
strScript = strScript + "window.location.href='" + strPath + "';";
strScript = strScript + "</script>";
ScriptManager.RegisterStartupScript(this, Type.GetType("System.String"), "Message", strScript, false);
}
}
}
catch (Exception ex)
{
throw ex;
}
}
/// <summary>
/// If CancelButton is Clicked,Page will be redirected to the Changepassword Page
/// </summary>
/// <param name="source">The source.</param>
/// <param name="arg">The <see cref="System.Web.UI.WebControls.ServerValidateEventArgs"/> instance containing the event data.</param>
protected void CheckSelectedStateValue(object source, ServerValidateEventArgs arg)
{
try
{
bool oldPasswordExist;
//Check for UserName and Password Valid
Hashtable has_pwdChange = new Hashtable();
has_pwdChange.Add("username", Session["UserName"].ToString());
has_pwdChange.Add("OldPassword", DAMS_Cls_EncryptDecrypt.Encrypt(txtOldPassword.Text));
oldPasswordExist = ChangePWD.CheckOldPassword(has_pwdChange);
// Check for oldPasswordExist
if (oldPasswordExist == true)
{
arg.IsValid = true;
//If oldPWD is Exist Then Value '1' is Assign to the Session Variable "Validapassword"
Session.Add("Validapassword", 1);
}
else
{
arg.IsValid = false;
}
}
catch (Exception ex)
{
throw ex;
}
}

You should call your DB to change the DB and return a value telling you if the old password was right or not.

You can simply use ViewState

NEVER put login or other security info into viewstate unless you are sure no-one will ever care enough to break into it. Or you hate the people you work for.

Hi.
I have a table , Like this :
<table id="MDS_Table">
<tr>
<td>sth</td>
<td>sth</td>
</tr>
<tr>
<td>sth</td>
<td>sth</td>
</tr>
<tr>
<td>sth</td>
<td>sth</td>
</tr>
</table>
How can I change background color of all <td> with javascript ?
Thanks in advance.

Brute force:
var cells = document.getElementsByTagName("TD");
for (var i=0; i<cells.length; ++i)
cells[i].style.backgroundColor="orange";Or some smart use of CSS:
<style>
table.orangeCells { background-color: orange; }
</style>
...
document.getElementById("MDS_Table").className = "orangeCells";
---- You're right.
These facts that you've laid out totally contradict the wild ramblings that I pulled off the back of cornflakes packets .

Thank you Shog9.
I used :
var table = window.document.getElementById('MDS_Table').getElementsByTagName('TD');
for (i=0; i < table.length; i++)
table[i].style.backgroundColor = '#af3830';

Hello
I am very new to all of this so I'm expecting to be made fun of if this is very obvious.
I am using a script to show a basic flash video on one of my pages. I would like to add a few other videos in the same place, with only one of them playing any time the page is viewed or refreshed.
I am using a GoDaddy page designer and the video is hosted at a different site that simply provides me with an "embed code" to paste in my page editor. I am hoping for a simple code that will allow me to plug in a few different "embed codes" from my videos and solve my problem.
I'm sure there is a simple code that will randomly select only one of the flash files to be displayed.
I would imagine this could apply to something like images, backgrounds, or any other type of file.
Can someone provide me with a code that accomplishes this?
Thanks

Thanks Richard
This is where I am completely out of my element. It looks like you may be right in that SWFObjects could solve my problem, however I have no idea as to where to start to create one.
I should have been more specific about how ingrorant I am to all of this. I am using a GoDaddy page designer and the video is hosted at a different site that simply provides me with an "embed code" to paste in my page editor.

Hi
I am trying to use client-side JavaScript to copy a local file across to the web server. What is the best way to build up the target string? If I hard code to path it works fine, but if I build up a string dynamically I get a "Bad file name" error using FSO CopyFile method.
Thanks, Ken.

|
|
|
|
Any spaces in the path? Try putting it in double quotes eg.
"c:\program files\myfile.txt"

Well sorry to waste your time. Ive since been advised that trying to use client-side FSO through ActiveX raises all kinds or security issues. As its a dot net web app, I'll have to revert to using a asp control to upload the file then do a postback behind code.
Cheers.

True enough, but I assumed you would take that into account. Anyway, no problem.

Hi
Im trying to show a PDF as the response of asn aspx. For this is i'm doing the following.
" Response.ContentType = "application/pdf";
Response.Buffer = true;
Response.Clear();
Response.OutputStream.Write(ms.GetBuffer(), 0, ms.GetBuffer().Length);
Response.OutputStream.Flush();
Response.End();
"
But the page is coming as a plain text as "%pdf-1.4@#....". When i try to see the content-type for the response using HTTPWatch tool i could see that its coming as "text/html ; charset: UTF-8"
The same page when is loaded in an IFrame is rendered properly as a PDF. But Iframe is not acceptable as per the needs.
Please help me in this issue.
Thanks and Regards
KC

I have an ASP .net app and an additional server side project to perform some transforms via XSL.
In the additional server side project I just load an XSL template depending on some params and perform a transformation (the results are passed back to the ASP .net application).
I'm not quite sure what could be the best approach to store and access the XSL templates:
-> I could implement the XSL "choose" logic in the ASP .net application and have the XSL in a web folder (just pass it back as a param to the external assembly).
-> Another idea was to embedd the XSL templates into my servier side assembly, but not sure if this only will work on the "EXE" world and not on the web (or if I could have performance issues).
-> The last one that I had was to add it as a resource and mark the copy to output directory,but again I think that won't be situable for the web world.
What option will work better in my web app?
Regards

Hello, I am somewhat new to web page development. I have a simple web page, in an Apache/Linux embedded environment. This web page has Form code with a textbox, and a button, of type="button". The button has a parameter OnClick="/www/apache/cgi-bin/myCode.cgi" which is a 'C' executable that performs low-level hardware coding of a temperature sensor, and places the temperature in a variable. Is there a way, either through javascript printf's in myCode.cgi, or through STDOUT, to send the temperature value to the web page, to be displayed in the textbox? I've spent many hours searching online for coding help and examples to similar problems, but can't quite find what I need to do. In simple terms, I click the button, the 'C' code gets invoked, and wish to have the information displayed in the textbox. I am trying to avoid the use of cookies, because my file system on the embedded controller is in flash memory, and wish to avoid write operations as much as possible. Backing up a little bit, I am somewhat new to javacript also, but have used it in other parts of my web page.
I appologize if I'm in the incorrect forum. A little coaching and info will be appreciated. Thank you.

I figured out how to do this. I used a javascript routine (sessvars.js, google this for more info) in both the web page and the C executable. Also had to use SSI in the web page, and enable apache for SSI (Options +Includes, and this parameter, "XBitHack on"). Used this SSI line in the web page: to invoke the executable. I have a button that reloads the web page, the executable is run, and the textbox displays the value from the executable.

That's why. Test and tweak in FF, then make it work in IE. Going the other direction is... painful.

Just a quick question:
I ran across the following operator in one of our application's javascript functions: !==
Has anyone ever seen this before? I can't find any reference to this operator using Google, but the code doesn't throw any errors when it sees this operator.
I started wondering if this is the opposite operation for "===". Any information is welcome.
Thanks in advance.

It's the opposite, if you like, of the identity operator ==
Non-identity[^]
