I think you mean you want to see the drawing slowly. When calculating the sinus values you should have a small delay in the for loop (like Thread.Sleep(50);). So your code should seem something like;
<br />
for (...)<br />
{<br />
y= Math.Sin(x);
ppArray.Add(x,y);
<br />
zedGraph1.AxisChange();
zedGraph1.Invalidate();
<br />
Thread.Sleep(50);
}

Yeah, nice try, but script tags are automatically ignored by the rendering engine. Along with a bunch of other HTML tags.

Is this conversation cover me from cross-site scripting? (Especially in asp.net post forum pages)
< to & lt;
> to & gt;
& to & amp;

From the few keywords in your "question", this belongs in the ASP.NET forum. Though I have no idea what you're saying because your "question" doesn't make any sense.

Acutually I want to prevent cross-site scripting in asp.net forums.
If I want to protect from user input data when user (lamer) enter script in the textbox in asp.net forms.
If I get to textbox string and convert the <, >, & symbol to HTMLEncoding in the string.
Is this process enough for prevent cross-site scripting?

Please do not use textspeak, for it is annoying to many people around here. Please be more specific about your problem you are having.

Hello,
Task is to add Thumbnail Images to a listbox control. Search on codeproject/Google showed me ImageListBox/ImageList controls. I tried these and eventually felt lost.
Can anyone give me a guidance on where to start? or any points to note.
Thanks

Hi,
this is what a ListBox shows:
- strings, if that is what you add to its Items collection
- ToString() results of whatever type you add to Items
- whatever you want if you do the painting yourself.
So you must go for "owner drawn" and use the relevant events.

Hello Luc,
Thanks for your response. I am afraid i didnt quite understand what you meant.
Could you please elaborate or point me to any other link?
Thanks

These are the keywords you need (for either ListBox or ComboBox):
DrawMode, DrawItem, and maybe: MeasureItem
I suggest you read up on them.

Hello,
My task is to open an Image Properties page programmatically. Properties page as you get by right clicking on the image and selecting Properties on Context Menu.
I know rundll32.exe can open up printer properties, Is there a similar way or any another?
Thanks

I don't believe there is a simple way of doing it. But you should be able to adapt this[^] to invoke the properties window yourself.
Take care,
Tom

I was testing BackgroundWorker and ran into this problem.
<br />
BackgroundWorker bw = new BackgroundWorker();<br />
<br />
bw.DoWork += new DoWorkEventHandler(bw_DoWork);<br />
bw.RunWorkerAsync();<br />
<br />
void bw_DoWork(object sender, DoWorkEventArgs e)<br />
{<br />
Form3 f = new Form3();
f.Show();<br />
}<br />
The Form f, is unresponsive. How can this problem be solved?
Using this code though, the form runs fine.
<br />
void bw_DoWork(object sender, DoWorkEventArgs e)<br />
{<br />
Application.Run(new Form3()); <br />
}<br />
Thanks.

void bw_DoWork(object sender, DoWorkEventArgs e)
{
Form3 = new Form3();
f.Show();
Application.Run(); //Begins running a standard application
//message loop on the current thread, without a form.
}
This explains, why the form was unresponsive. The messages were not handled at all. With a Message loop, the form works fine.
Any more ideas ?? Maybe there's a better way to do this??
Thanks.

It won't work because the form is cut off from the application message pump by the thread boundry. In order for the form to work, it has to be on the same thread as the message pump. The message pump is created by the Application.Run() method. It's NOT a good idea to run multiple pumps inside the same app to get around that limitation. UI elements should stay on the main thread.

Hi Dave, thanks for the info.
So, the appropriate thing to do would be do would be:
- do all the main processing in DoWork function
- Send the required information to displayed by UI via. ProgressChanged or RunWorkerCompleted; unlike what i did by creating a Form or any other control inside the thread
- The UI controls stay in the main thread in this way.
Thanks.
