Loop through each character of the password and count the numeric,alphanumeric or special character as per your requirement...
if any of the counter is zero show the messagebox and dont let user to proced..

As per the first answer, or you could use a regular expression to validate the input. Has the advantage of only the expression needing to change if you decide to change your validation.

Here you go. I used this script on one of my sites-

function validatePassword(fld) {
  var error ="";
  var pwdFilter = /^\w*(?=\w*\d)(?=\w*[a-z])(?=\w*[A-Z])\w*$/ ;

  if (fld.value.length < 7 || fld.value.length > 20) {
    error += "-Password must be 7-20 characters\n";
  }
  if (!pwdFilter.test(tfld)) {
    error += "-Password must contain at least 1 number, lowercase, and uppercase\n";
  }

  if (error != "") {  
    alert("Some fields need correction:\n" + error);
      return false;
  }
  return true;
}

That is the Javascript validation. You can call it onSubmit of a form-

<form method=POST action=register.aspx name=demo onSubmit='return validateForm(this)'>

Try that out. Good luck!

If you have the regular expression, just use a RegularExpressionValidator. Saves wiring up your own validation routine!

Render Another Form

Hi,
I have an HTMLForm of a page in Session.
I change the form object (add a control) in another page.
Now how could I render the first page again to apply chages?

Best wishes

If you are posting back from PageA to PageB, and then want PageB to render PageA, that isn't possible in ASP.NET. Each page can only render itself...however it is possible to post back from one page to another, or transfer control on the server from one page to another.

The only solution to your problem that I can see would be to post from PageA to PageB, let PageB do its thing, then Server.Transfer back to PageA and add the control to the form of PageA and let it render. The problem with this is that the URL displayed to the user will probably be the URL of PageB, not PageA. You won't be able to modify the form of PageA from PageB either...each page would modify its own UI.

I have a measurement device that measure and sends a data update string to the PC once a millisecond, so you can see what's happening in real-time. I would like to let authorized people see my data via the web in roughly real time using a web browser such as Internet explorer. I have an internet connection with valid IP address that whole of day is connected.

My idea so far, is to divide the problem into originator (my PC putting data on database) and clients (pc's logging into my computer via web browser to see latest data).

Originator:
I thought I would use SQL database to save average measured data into the database every one seconds.

Clients:
This has to log in, see designed GUI, select charts, table and reports via menu.

I want to keep it in C#.

I am very keen to hear any suggestions
Does anyone know how I can do this?

With best regards,

You need to buy a book and workout the examples provided. When you learn things, go and start the project. Whatever you asked can't be done without having a knowledge on ASP.NET. This site got many articles and sample projects. But as a beginner, I recommend reading a book before you look at the articles.

All the best Smile | :)

AJAX[^] is the answer. To make things easier, use AJAX toolkit for ASP.NET.

What the hell is wrong with you? You ask a question, you're given the de-facto answer and you want a different way of doing it just because you're not familiar. How do you think people learn new concepts?

I would prefer you to use AJAX but here is one other solution.

From javascript make a call to dopostback method with eventtarget and arguments (if reuqired) and in Page Load method check for the event target and call the C# method. Remember this is dirty trick.

JavaScript (JS File)

__doPostBack('CALL_MY_METHID','');

ASPX Code Behind

void Page_Load(object sender, EventArgs e)
{
....
....

// Insure that the __doPostBack() JavaScript method is created...
this.GetPostBackEventReference(this, string.Empty);

string eventTarget = (this.Request["__EVENTTARGET"] == null) ? string.Empty : this.Request["__EVENTTARGET"];
if (eventTarget == "CALL_MY_METHID")
{
  // Call your C# method here and return
  CallMyMethod();
  return;
}
....
....
}

Be careful, there is no Undo Button(Ctrl+Z) in life.

.NET is parsed by the server. Javascript is parsed by the browser. If you have page that is already loaded that you want to process a .NET page, asking the server to do so via Javascript is the best way.

PageMethods vs HTTP Handlers

2-Feb-09 23:03

If we are calling a server side function we can use a number of way.
I use mostly static PageMethods ([System.Web.Services.WebMethod]) using Ajax or HTTP Handlers. Can anyone please tell me which method is better and the pros and cons of each.
I keep performance and response time the first criteria.

Thanks.

We can call server side function by
1. writing a static function ([System.Web.Services.WebMethod]) in code behind using PageMethods.
2. calling an HTTP Handler and returning the string.
by using Ajax.

My Question is which method is faster. I want to know about the pros and cons of each.
