Is there a tutorial that will help in creating a RS232 driver?

I am attempting to write a driver / VI that will control an Animatics "SmartMoter" via a RS232 port. I was able to download sub VI's from www.summerfiles.com.
Is there a tutorial that will help in creating a driver for a RS232 port? I take it that I will need to connect these sub vi's in a correct sequence to be able to communicate through the RS232 port.
Thanks,
Bill

It seems that what you downloaded is a driver. What you need to determine is how to use the functions on the driver to create a high level application. There is a tutorial at http://zone.ni.com/devzone/cda/tut/p/id/2804 that might be useful. The driver you downloaded is lacking in several areas. One of which is documention. Each VI should include a description of what it is and what it does. Each control/indicator should also include a description. I could not find any such information in these VIs. I didn't look at everything because the horrid front panel colors in the SmartMotor.llb was giving me a headache. I did see a VI called SM Tester. This appears to be a high level example that you could use as a model.

Is there a tool that will help block metadata of online activities?

Do private tabs and the like work on browsers? I don't think they do as I still get targeted ads sent to me. I am tired of advertisers snooping and want to stop their geo or other targeted stalking. Gives me the creeps they grab metadata from gmail and my browsing activity. Is there a way to REALLY be private, other than going back to 19

Your description of the problem is not quite clear so I made certain assumptions. I hope I am rigtht. I believe you have a color patch such as this:
that you would like to place in an image area that has modeling in its white background. You do not want to lay in a flat color but rather to add a color and not lose the modeling or other background tone. The problem is, after making the selection, if you use Edit > Fill and set the Blending mode to Color, the white background remains white. The only colored background area may be an object's shadow or some similar area that is not pure white. (Image 2) It is an unsatisfactory result.
If that is an accurate description of the problem, consider this:
Image 1: The original image
Image 2: Edit > Fill with the Blending mode set to Color. White remains white
Image 3: Mode changed to Lab Color. Edit > Fill with the Blending Mode set to Color. Then return to RGB.
(I would not normally use this green as a replacement color but since it is a Tiffany clock, I chose a light version of Tiffany's trademark color.)

My MacBook Pro is running very hot after lion install. Are there any hardware changes that will help? What can I do to get it back to normal?

My MacBook Pro is running very hot after lion install. Are there any hardware changes that will help? What can I do to get it back to normal?

I get the impression that most of the users on older hardware experiences similar temperature issues on Lion for a long time now. Awaiting for confirmation from the original poster.
In the meantime I'm just cautious with regards to pushing the machine to such extreme temps, since something tells me such behaviour which includes monitor flickering and the likes is nothing but abnormal for any type of use...
Any clues if 10.7.5 does anything on this? If not I'm afraid i see myself going back to SL for good...

I know alot may say what you have to hide but ive got nothing to hide i just want one on there so my privacy is not broken by friends and family if they fancy playing on my phone and having a snoop round my phone.

If you visit these forums often, you will read about the 2 year old child who accidentally wiped out the parents phone, the kid who set a passcode and didn't remember what it was, etc etc etc
Passcode your device. Protect your device. It really isn't a toy. The toy is the iPod touch.

Hi there dcjoe,
A lot of places carry the cables you are looking for. Though your area may vary I have found them in places like radioshack and wal-mart. Here is a google shopping link to get you started. Let us know if this helps.
Best of Luck!

HT201541 Our Mac-Mini has gotten slower and slower. Is there a utility that would help speed it up?

Our 4 plus year old Mac-Mini has gotten slower and slower. Is there a utility that would help speed it up or is there another?

Hello! I’ve offered the steps below to similar posts in the past and they helped out getting to the solution (or at least find the cause). I suggest them to you too in this case. It will take you about 30 minutes or less to do these, depending on how bad the problem on your Mac is.
The goal here is to boot your Mac to the so-called Recovery partition where you’ll have a chance to repair the disk and the disk permissions using the Disk Utility and Password Utility. This might solve your issue and even if it doesn’t- it’s still a decent maintenance step to perform. These steps won’t erase your data or reinstall your Mac in any way if you follow instructions carefully.
Here’s how:
1/ Make sure your computer is completely shut down.
2/ You’ll have to be quick next: Press the Mac’s power button. As soon as you either hear the loud chime, or see the display light up - usually after a second or 2 - on your keyboard press [cmd] + [r] Keep these keys on your keyboard pressed until you either see an Apple Logo with a loading bar or a spinning gear.
After a few minutes, you’ll be presented with a Utilities screen. This is the Recovery partition. If this step is already giving you problems, try using a USB-keyboard. It doesn’t have to be an Apple-keyboard. If you have a Windows-tailored keyboard laying around, use the “Windows-flag” key in stead of the [cmd]-key and it should also work.
3/ Choose Disk Utility and click [continue]
Disk Utility will display your computer’s harddrive in the left column. The default name for it is “Macintosh HD” and is usually the second one from the top. Click on it and click on the [verify disk] button. This will check your “Macintosh HD” harddrive partition for errors. If found, click [repair disk] unless you have a Fusion drive in your Mac and it says [fix] instead of [repair disk] please tell us before you continue! For a screenshot of what I mean, check this article from Apple: http://support.apple.com/en-us/HT202574
4/ Once done with the verifying or repairing of your “Macintosh HD” click [repair disk permissions]
This will check your partition for permissions errors. A common myth about this feature is that it will fix all permissions issues on your Mac, which is not true, but it will fix most systemwide issues. Also, here is a list of error messages that you can safely ignore if they pop up:
http://support.apple.com/en-us/HT203172
5/ Lastly we shall do a permissions/Access Control List repair on specifically your user’s home folder with a somewhat hidden tool in the Recovery partition. Close Disk Utility and find the menu called “utilities” in the top left corner of your computer’s display. It’s in between the menus “edit” and “window” Don’t be confused with the menu called “os x utilities”
Choose Terminal. A somewhat old-fashioned looking window will pop up, waiting for a text command from you. This is the Terminal.
After the # type: resetpassword and press return. Note that there is no space between ‘reset’ and ‘password’
What you’ll see next is an rectangular window that gives you the option to reset passwords. We are not going to that, however. Instead, click on “Macintosh HD” at the top. In the pull-down menu below that, choose your user's accountname. Skip all the rest and at the very bottom click the [reset]-button.
A spinning gear will appear and may stay on for a second or several minutes. It’s hard to predict exactly how long.
If you have multiple users on your Mac, I advise you to repeat this step for all your users.
We’re ready to reboot your Mac now. Click on the Apple Menu and choose “startup disk” Choose to boot from “Macintosh HD” Please let us know if this solved your issue, or if the steps above did not work, or could not be performed for some reason.
If they worked I suggest you do these steps everytime your Mac becomes slow.

Is there any way that will notify me first before purchasing in iTunes? I have lots of purchased in iTunes in my credit card.

Is there any way that will notify me first before purchasing in iTunes? I have lots of purchased in iTunes in my credit card that I didn't buy. Pls help.

You should be prompted to enter your password when buying, if you aren't then on your iPhone you can set Settings > General > Restrictions > Require Password to 'Immediately' so that it has to be entered for every purchase (that setting has a default of 15 minutes during which it doesn't need re-entering).
If you've been charged for items that you haven't bought then you can try contact iTunes Support via this link : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Purchases, Billing & Redemption

Is there any Adobe product that can help me create crochet charts/diagrams?

Is there any Adobe product that can help me create crochet charts/diagrams?

I am not all that familar with Crochet, other than what my sisters and mother use to do 20+ years ago.
What you could do is turn on the background grid and snap to grid. Find a grid size that will work for you (may be easier if you place an image for reference) Then with the pen tool you can create lines that follow the grid (assuming you want to print the grid)
With the image placed you could add text for what color or change the lines color and print it out
Anyway just an idea, it kind of hard to think with out seeing one. But then again if you have book of patterns you could use that as the reference. Just keep in mind that whats in that book is for your own use only, it can not be shared or sold to the public. As the book is protected by copyright laws. Any original work you do that is not in that book, is up to you on what you want to do with it.

I have an iphone 4s, I installed Vtok but the video chatting part of the app is not working when I try to chat with my husband through gmail on his PC. Can I fix this or is there another app that will let me chat with my gmail chat contacts?

Vtok video chatting is not working on my iphone 4s. When I try to do a video chat with my gmail chat contacts who are using a PC we each only get the voice part of the chat and no video. Is there some way to fix this or is there another program that will let me video chat with my gmail chat contacts? Thank you.

You can not merge accounts.
Apps are tied to the Apple ID used to download them, you can not transfer them.

CS4 will not open Nikon D7000 NEF files; Is there a DNC that will open them?

I have CS4 and Light Room 2
Apparently there is no Camera Raw update for the new Nikon D7000 NEF files for CS4.
I therefore down loaded the Adobe Digital Negative Converter Verson 6.3.0.79 which is compatible with Camera Raw 5.4 or later.
Using that DNC, when I do step 1, "Select the images to convert" I get the message "No items match your search". It apparently is not recongnizing the D7000 NEF files.
Is there another DNC that will open and convert the D7000 NEF files?

I just bought the d7000 yesterday and was experiencing the same issue with cs4. I downloaded the DNG converter from adobe and selected the whole folder where the raw files were located (I was unable to select individual images) and it worked fine. It processed the files one by one with new name (without the $500 CS5 pricetag for now). The DNG files open in bridge and psd. Perhaps try selecting the folder? Good luck.

Is there an App that will sync with microsoft outlook calender?

Is there an App that will sync with microsoft outlook calender?

OK here is a problem I have with my calender- all the events are added mutible times for each event- at least 4 of each. So how do I get all of these mutiable events down to just one event. Now this also includes hollidays and personel events on the calender from outlook. All this I think happened after sync to Cloud- not sure, could have happened after OS 5 update!!! Now this is on my iPhone 4. Now going to my calender on my home computer in outlook no events or holidays are showing in the outlook my calender. If I go to the icloud calender it has mutiable events and holidays like on my iPhone. Now how do I fix this without causing a problem with my other programs?
