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.

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.

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();
// Set the properties here
if (fs.ShowDialog() == DialogResult.OK)
   {
   // Get the changed properties here
   }

How to use chrome webbrowser in C# .NET windows form application

5-May-15 1:43

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" Smile | :)

There's a library available called "Chromium"; you'll need the SDK and the C# bindings.

Google knows where to find them.

How to use "altChunk" to put HTML into a MS Word object that is embedded into a PowerPoint slide?

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. :

Hi, I'm fairly new to C# and recently I started developing a speech recognition program. At the moment I have a grammar builder which reads from a text file. This means it will only recognise a command if it's in that text file. I would really like to implement Google speech in to my program so I can search google, youtube etc without adding it to a text file. I know you can do it because I've seen people do it and it works by sending a audio file and then Google sends back the closest to confidence text.

If possible I'd really like for someone to help me to implement this. My current code(the rest is just commands) http://pastebin.com/yukznbeD[^]

Yes this is something that I'm looking for but I'm not sure how I would implement this into my C# project.

You start by studying the documentation.

I've been reading various articles and topics over the past few days. But most of them are either how to implement them into a website or something else. I just found a vb.net code snippet of how to do this so I converted it into C# so I have the right code I just don't know how I would record a flac file or add it to my code.

I have no experience with that, but did you take a look here?

I just downloaded this and spent some time looking at it. It looks useful although I have no idea how to implement all this. I'm thinking about hiring someone to do this for me because there is no way I'm going to be able to do this.

Well, you will never be able to do it unless you at least try.

If you hire someone, all you will get is more code you don't understand, can't maintain, and which doesn't help you with the next version.
If you at least try, you may learn something - and sufficient learning means you ended up doing it yourself all along.

But...if you want to hire someone I suggest you go to Freelancer.com and ask there.
But be aware: you get what you pay for. Pay peanuts, get monkeys.
