Try this: How to: patterns[^]
Or did you have a different pattern in mind? You have to be specific, you know!

There's a pattern that people who post here for the first time often don't ask good questions.

Your first "go to" pattern should be "Google".

A pattern is a description of a way to solve a common design problem. The behaviour and terminology is formalised, so that people use the same terms when describing these solutions. There are many great resources available for learning about patterns. The classic example is the Gang of Four (GoF) book[^]. It's a bit hard to follow when you're first learning it, so I'd recommend something like the Head First Design Patterns book. Beyond that, take a look at dofactory.com[^]. They have lots of examples of patterns.

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
Perhaps if you show us the code you used and explain where the link is, it might help?

Look at the source of your received email. I guess there's still just www.adobe.com and your email client just displays it as a hyperlink.

My email source as below:
<html><head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
.Arial { font-family: Arial, Helvetica, sans-serif; } .myFont { font-size: 12px; }
</head>
<body>
Dear Customer,
To download Adobe Acrobat Reader you can visit on www.adobe.com.
</body>
</html>

Isn't that the answer for you then?

Yes, it converts it into hyperlink.
|
|
|
|
|
Your email client displays it as hyperlink. Other people using other mail clients might see it just as it looks in your mail source. There's nothing you can do about that.

Put the url in single quotes; e.g.
To download Adobe Acrobat Reader you can visit on 'www.adobe.com'.

Sorry, you will have to give us rather more detail than that!
This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
So try describing exactly how you want it to work - do you want separate forms? Or on the same form? What does your menu look like? Are you using WinForms? Or WPF? And so forth...
And then explain what you have tried, and where you are stuck - we need to know so we don't try to give you a solution you have tried, or a solution you can't understand yet because you haven't covered it on your course!

I am trying to make application which communicate to my device with RS232 and I make a main page and the setting page now i just wanted that in my main page when i click the Setting button a pop-up will open which is my setting page.
I am using WinForms

OK - so create a new form, and call it frmSettings.
Populate it with your controls, and add "OK" and "Cancel" buttons.
For the OK Button, set the DialogResult property to "OK"
For the Cancel Button, set the DialogResult to "Cancel"
Highlight the form, and set the AcceptButton property to the OK button.
Then set the CancelButton property to the Cancel button.
Add Properties to let you transfer data into and out of your form.
Go back to your main form, and add this code to your Setting button Click event handler:
frmSettings fs = new frmSettings();
if (fs.ShowDialog() == DialogResult.OK)
{
}

OriginalGriff already gave you a good answer. I just want to mention for your better understanding that you misunderstood the meaning of "Multi Page Application". You can safely forget about that and about "ISwitchable" and "Magellan"

Hi,
I'm going to use HTML5 in C# windows form application.
But WebBrowser tool in my toolbox does not support HTML5.
So, I want to use chrome browser in my C# application.
Please help.

There's a library available called "Chromium"; you'll need the SDK and the C# bindings.
Google knows where to find them.

Ok so I saw the cast on "altChunk" (https://www.youtube.com/watch?v=couuEc6eEjE) and the blog (http://blogs.msdn.com/b/ericwhite/archive/2008/10/27/how-to-use-altchunk-for-document-assembly.aspx), especially the HTML section. I am very new to XML and it's tools and I have been struggling to put all the pieces together. 85% of code is from research and altered.
OBJECTIVE: I have a PowerPoint slide template that has a couple of text fields that I fill (id [uic], name, PreviousDate, CurrentDate, ...) then it has two embedded word objects representing Previous Notes and Current Notes respectively. These two embedded Word objects are what I am trying to put HTML in. The HTML comes from user input via the web and stores it in a DB field. So I am looping through my data rows-->creating a copy of the slide template-->filling the placeholders (id [uic], name, PreviousDate, CurrentDate) with the data from a row-->then I am trying to fill each embedded Word object with it's HTML data-->save the slide and start the process over for each row of data.
Here is what I have so far. I have gone down many rabbit trails but I have tried to clean the code up to show just current code. My current issue is that when the slide saves it disposes my object/connection/stream(?) so I can not fill the second object. Do I need to not save until I fill both Word objects? I see the "altChunkID" but I can not tell if it actually references anything. Do I need to declare an XNamespace for the altChunk relationship?
I think I am close, but I just missing a few pieces that tie it all together. Any assistance would be educational and greatly appreciated. Below is my code; starting with a call to renderPPT(). ...Thank you in advance. :
