How to make a Web Page with Labview?

I have a Project: CONTROL A CAMERA OVER INTERNET (with Labview)
i try to make a Web Page but it s very difficult for me.I have Labview 8.6 and Internet Toolkit.
Why can i make a simple Web page?
Why can i control the camera over Internet?
Thanks...

This thread is quite old but there is a new answer that might better suite your needs... So, for those who are looking for the answer, have a look at WebPager plugin for LabVIEW here: https://labicom.net/labdeveloper/WebPager/ . It will make much better job (in most cases) than Remote Panels and Web Services suggested above. The only difficulty I see in your request is a 'camera' word. With WebPager you'll be able to control it from the browser (without any plugins or similar things), but the video image itself will pose problems... Still, it can be tackled.

My Macbook Pro is frozen on the login page with a white screen and only my login picture. How do I fix this? I can't turn it off and I closed it and let it charge but it's still not working.

My Macbook Pro is frozen on the login page with a white screen and only my login picture. How do I fix this? I can't turn it off and I closed it and let it charge but it's still not working. It's only 3 months old and was working perfectly fine 30min before this happened.

Hello Kierasully,
I would start your troubleshooting with the article below for issues of not being able to log in to your Mac. Start with booting up in to Safe Boot as well as resetting PRAM on your Mac. If that does not work, then verify the hard drive with booting to the Recover HD and go to Disk Utility to verify it.

How do I make a facebook page with a premade template? [was:help]

how do I make a facebook page with a premade template i bought on etsy? I have asked this 10 times now In all diffrent section here. I guess I dont even know how to ask a question in photo shop?? I am very glad I am only on the trial. This is soooo NOT user friendly!

Tip for a forum newbie: please use a descriptive subject header to post your query so we have some idea of what your question relates to.
"Help" tells us nothing. Try "how do I make a facebook page with a premade template?"
You've posted this question 3 times in 3 different forums but we've no idea which Adobe software you're using or where your template is from. There is a reply in the Photoshop forum asking for more information.

Is their any tutorials on how to make a navigation bar with drop downs in Dreamweaver CC now ?

Is their any tutorials on how to make a navigation bar with drop downs in Dreamweaver CC now that they do not have the spry option?

bbull2005 wrote:
Preran, why wouldn't Dreamweaver include it's own menu/navigation bar widget?
I can't answer on Preran's or Adobe's behalf, but I think you'll find at least part of the answer here: http://wiki.jqueryui.com/w/page/38666403/Menubar
Adobe decided to discontinue development of Spry in August last year, and Dreamweaver CC made the switch to using jQuery UI widgets and effects. One reason for dropping Spry was that it failed to work correctly in some browsers. Judging from the fact that the jQuery UI menubar is now "on ice", creating a flyout menu that works reliably across all devices is proving more difficult than originally envisaged.
Because all other widgets in Dreamweaver CC use jQuery UI, it's a reasonable assumption that Adobe hoped the jQuery UI menubar would be ready in time, but it wasn't.

Create a login page with NI Security Programmatic Login.vi

Hi everyone,
I'm trying to create a login page that inputs username and password of users, then authorize user information with the Domain Account Manager to recognize user identification.
I google and see the NI Security Programmatic Login.vi can allow me to create a login page and it works. However, I got a problem is to redirect to other pages after authorizing.
NI Security Programmatic Login.vi only outputs some string to show the status of the authentication, it doesnt output boolean like true or fall.
Does anyone has a solution to help me?
Thank you.
This is my screen shot:

Thank you for suggesting me. I've done the checking task but I don't know how to call a subVi.
As you can see in the images I post below, I have a login page with its diagram, and the main page that I want to show after logging in conrrectly.
So should the main page is the subVi or the login page? And can you tell me how to show the main page after logging correctly?
I also don't know how to refresh the page if logging information is incorrect. Do you have any solution?
Thank you so much.

How link my Facebook's page with my web site?

Hi!
How link my Facebook's page with my web site and have a preview of facebook's page on my website builted with iweb?
Regards
Thanks a lot.

I think it's the other way around. Sharing a webpage on Facebook.
Here's how : http://myipad.atspace.com/size/Share.html
But if you want your FB page embedded in an iWeb page then paste the <iframe> code in a HTML Snippet.
<iframe src="http://url.to.file.html" frameborder="0" width="500" height="500" scrolling="no" allowTransparency="true"></iframe>
Where SRC="" is the URL of your Facebook page. Change the numbers for witdh and height to make the FB page fit your webpage.

Note: Please write as detail as possible because I am new to vb.Thx again.

Hi,
For a lack of info about what Applications you are talking about we can only guess at what you want to do. In my experience, this is the kind of question that ends up being a mile long with 15 different examples because nobody knows exactly what you
are trying to do.
With that said, maybe you can put a ListView in your TabPage and use the code i showed in the link below. If not then please explain exactly what you want to do. 8)

Use Exchange 2010 OWA Login Page with Exchange 2013

We are planning on upgrading our exchange server from 2010 to 2013. We want to keep 2010 OWA login page with this upgrade. Partly due to educating users to new OWA interface and no plan to upgrade to office 2013 anytime soon.
Questions:
1. Do you or do you not recommend?
2. Is it possible?
3. How to keep 2010 OWA login page during and after migration to 2013 (instructions)?
Thank you!

Hi, EthenLEC
I agree with Andy David.
For additional information, we can change OWA 2013 back to OWA 2010 interface to use light version by the following steps.
Log in to OWA 2013.
Once logged in, click on the settings gear in the upper right corner, choose
Display Settings.
From the Display settings menu, choose Outlook Web App version, then check the box to use the light version.
Sign out of OWA and sign back in. Now it has the OWA 2013 light version.
Best Regards.
