Hi All
I have a requirement similar to that seen on codeproject website.
I have a requirement which will allow the user to add HTML text in a control(most appropriate Textbox control in multiline mode) and then save it in a file or database.The text will be displayed later when the user visits the page.
And I want to allow only some HTML tags not all.
For eg Codeproject allows the tag for code and pre
And if I write a script alert("Hello world");
tag is ignored in codeproject.
1.How can I achieve this????
And also when we submit the article on codeproject we add the text in textbox control but when our article is published we see our article on a page not in a control(label).
2.How is this achieved??????????
Please provide guidance for the above two requirements
Thanks
The SK

Use Regular Expression to select from your html the part you want to show and what you dont want to...
Something like this <TAG\b[^>]*>(.*?)</TAG> (there are lot to improve in this expression)
Choose appropriate regex to select the part to omit.

Yes. You have to use Object Tag for that . Just few line of Code !
<object width="500" height="500">
<embed src="PATH_TO_YOUR_FILE" type="application/x-shockwave-flash" width="425" height="344"></embed>
</object>
If you want a complete go through please read this Article in Code Project

I am using multiline text box.i set size of it 200.

and i am also using RangeValidator of set the fixed no of char.
But it will not working ,it will accept more then 200 char.
plz anyone help me.i will very thankful for him.

MaxLength property does not work for when you set Textmode="multiline". So, you can use ValidatorControl to Validate the range. I am not sure why this is not working for you. You can Try like this.
<asp:RegularExpressionValidator ID="RegularExpressionValidatorForMultiline" runat="server" ControlToValidate="txtMultiLineText"
Display="Dynamic" ErrorMessage="Please limit to 200 characters or less."
ValidationExpression="[\s\S]{1,2500}"></asp:RegularExpressionValidator>
Another alternative solution is to developed one custom control. I found one great article in Codeproject It self.
Extending the ASP.Net Multiline TextBox control to limit the number of characters entered[^]
And For your more Information Read this Post
MaxLength ignored in multiline textbox.[^]
Hope this will resolve your problem.
Let me know if you need more help.

Hi,
You can use JS to control it.
In page:
<script type="text/javascript">
function validatorTextLength(obj)
{
if(obj.value.length==200)
{
event.keyCode = 0;
return ;
}
}
</script>
And in CodeFile, you need to set
TextBox1.Attributes.Add("onkeypress","validatorTextLength(this)");
when pageload.
Good luck.

This means, there are some problem is your code. What do you mean by "Pc1 Session Variable Effects Pc2 Session variable".

If we same username from different systems it doesn't effect session from used for same user in another system, ASP.net uses seperate session for each request from different systems or different browsers. If you dont want two users to use same username you can make use of database to check if the user is already logged in or not, Or you can use array of users in global.asax file where the data is global for all usersm, so that you control the user while loggin in (Checking with the global array)...

Dear frd's
Is it possible to read data from serial port of client system using asp.net web site. Here is my scenario
I will be having computers connected in LAN and a web application which resides on server. Each client computer will be connected to a external machine using serial port and is ready for reading data, external machine measures equipment details and sends through serial port.
Now I need to read the same data using my web page, is it possible?
Like when we do video chatting our web page reads data from web cam and sends the stream to web page. this way how can I read data from client machine to web page.
Please give me suggestions on how to proceed for this.
Thanks & Regards,
Anil Chelasani

I think that your login button works by Ajax
If I think true
if your login button is a asp.net control you can use OnClientClick property and set it by a
javascript function name
<asp:Button OnClientClick="return loginFun()"/>
I emitted other irrelevant properties in the pervious code
if your login button is a HTML control you can use onclick property
<input type="button id="loginBtn" onclick="return loginFun()"/>
and in loginFun you show the progress bar
function loginFun()
{
[Your codes]
document.getElementById("progressBar").style.display="inline";
}
and when your ajax response is recieved you can use this javascript code to hide that
document.getElementById("progressBar").style.display="none";
hope to be useful

thank you for anwser, but i don't have e progress bar, i have a gif picture, can you helm me to show a gif picture when i click on logon button ? Thank you

first I want you to answer my question
Q - how does your login button works?
when you click on the button what happens.
the form would be submitted
Or
a XmlHttpRequest (Ajax)would be sent to server for login action
(I answered this situation later)
--------------
about first situation
if form submit is occurred you can not use a progress bar(show an image) to show progress
because whole of your page would be refreshed.
I think that you must study more about HTML and Http to understand what happen when the form submitted
Hope to be useful
