Regression of 8.5 to 8.6 using a waveformgraph without a trace

I have a regression bug for updating my code of measurement Studio 8.5 in 8.6.1.

Reproduction:

1. create a new Windows Forms application

2. Add a WaveformGraph to the form

3. Add a slider on the graph

4. specify the Cursor Position in X = 0 property

5. get rid of the automatically inserted plot to manually delete the field and all references using the code editor.

6. launch the project

8.5, works.

However, a null reference exception happen with 8.6.1, in the cursor EndInit method.

As you can see, a graph of waveform without any plots is created. If this is not achievable by working with one designer, it is a requirement in my project and it worked very well for a long time.

Step 4 the omission also solves the problem.

I would very much like to see this problem fixed in a future version of Measurement Studio.

Hi Christian,

I could reproduce it here.

I will forward it to the R & D

    Hello

    Did you mean an office or a note?
    As far as I know the a Note is part of the recovery Image and the CD is not supplied with the unit. In addition, Toshiba units are not delivered with the Office 2000 software.

    Hello

    You can enable the detection of wrist as well as an access code and unlock it with the iPhone:

    • On your iPhone, in the application of the watch, go to: My Watch (low left tab) > General > wrist Detection - this turns on.
    • On your iPhone, in the application of the watch, go to: Watch My > Passcode > Passcode turn on (choose a Simple 4 digit access code or a longer).
      • Also in the password settings screen, select Unlock with iPhone.

    After putting on your wrist, your watch don't unlock then after whatever you do first: unlock your watch manually or unlock your iPhone. Then, it will remain unlocked until you delete the monitoring of your wrist, when that it locks automatically.

    You can also set your watch to the screen to reactivate automatically when you lift your wrist, even select what is displayed on the screen to wake up:

    • On your iPhone, in the application of the watch, go to: Watch My > General > screen Wake:
      • Active screen Wake on revival of wrist, and;
      • Choose if the watch should resume last activity or see the Face of the watch.
  • HP deskjet 2540: stop page print quality and 'use printer wireless without router' printing

    After installing the hp deskjet printer 2540, all operating systems (vista, windows, mac os, windows 8) correctly printed.

    I would like to prevent the printing of print quality page whenever the printer is on and to prevent print also the page "use printer wireless without router" (it would be better not to waste the ink).

    Thanks for any help you can provide

    Hi there @lesart55.

    Welcome to the HP community!

    I have seen your post on how your Deskjet 2540 prints a page of print quality every time that the printer is on, and also the page "use printer wireless without router" is printing.

    I'll start with the PQ page that prints at the start of the printer, as it is normally a sign of a hardware problem with the printer.

    Try to update the firmware on the printer. Here is the link to download and run the update using a USB connection to your Vista system: HP Deskjet 2540 series Firmware update

    Try a reset of the power to the printer and make sure the printer is plugged directly into the wall, avoiding bars power and surge protectors. This ensures that the printer is full on and can help greatly.

    Press the power button to turn the product on.
    With the product, unplug the power cord from the back of the product.
    Unplug the power cord from the wall outlet.
    Wait at least 15 seconds.
    Plug the power cord into the wall outlet.
    Reconnect the power cord to the back of the product.
    If the product does not light by itself, press the Power button to turn it on.

    If the PQ page always print after you are done troubleshooting, try the steps outlined in this guide below. I looked at the steps that I see would take place in the tent for your specific problem and chose the steps following, Please do not take account of the actual title.

    An "Incompatible cartridge or"Missing cartridge"Error Message is displayed for HP Deskjet 1510, 2540 Deskjet, HP Deskjet Ink Advantage 1510 and Deskjet Ink Advantage 2540 all-in-One Series Printer"

    I hope that the problem has been cleared up for you at this stage. If this isn't the case, please call us directly to discuss your options of the printer!

  • After 4 years of use my computer without any problems at all, I get a message saying that my copy of Windows Vista is NOT activated.

    Original title: Vista Activation issue

    After 4 years of use my computer without any problems at all, I get a message saying that my copy of Windows Vista is NOT activated.

    Of course, he was and has been deleted now tile view! I made no changes to anything on the computer, so I did a little research

    and found that it could be a virus trying to get 'paid' for a new activation code. I did a complete reinstall of Vista to remove

    such viruses or errors and it still say my copy of Vista is not activated. When I try to follow the steps to activate Vista,

    I got nowhere! Everything I've read say s do the activation of the phone, but my computer doesn't give me the option of phone!

    It gives me only 3 options - "Buy a new online product key", "Enter a different product key", "Contact Hewllet Packard to help solve this problem."

    I called HP and of course my warranty has expired and they even want to talk to me about $100! I'm going crazy trying to figure this out! Help someone?

    Thanks for the reply, but I tried ALL the links you've posted over and over again until I've already posted my question here! The links you suggested sent me round in circles! They say all "choose the Activate by phone option" but I was not getting the phone option on my computer for some reason any.

    I have corrected the problem and HERE IS HOW - 1-800-Microsoft

    It was as simple as that! Now, if only they post this number somewhere here on the site it might save people hours or days of research! After calling the number, work your way through the automated system until you get a man! The guys at Microsoft that answered the phone was great and had activated me and up and running in minutes!

  • BlackBerry smartphone how to configure and use e-mail without BES

    Hello

    I'm trying to figure How to configure and use e-mail without using a BES.

    I checked with the local telephone company. And the number is not ascociated with any service of BES.

    The entry of services show no indication in this sense.

    In addition, the configuration of SIM card show that everything is disabled. This means that the phone is unlocked. At least that is my understanding.

    However, even after a wipe, the BB device does not set up an e-mail account, as described in the manual. He keeps asking for a BES activation first.

    What will do that disappears?

    And to allow the configuration of the "spam"?

    Just develop the right answer given by JSanders, you can always access your email accounts and social networks (facebook, twitter, google +, etc) on your phone, you will just have no notifications PUSHED to your phone.  You can access the internet on your phone in order to access these accounts, but it should go to them.  With BlackBerry Internet Service activated on your phone account, RIM will push these notifications of new emails, facebook messages, new tweets etc. for your phone.  That's what you'll be missing out on without active BIS.

    I wanted to just make sure that there is no likelihood of confusion.

  • How can smartphones blackBerry I use my Pearl without the scroll ball?

    When my Sidekick wheel would spoil, I was able to use the access keys or the shortcuts that allowed me to use my phone without having to depend on the scroll ball. This phone has the necessary capacity to do so?

    No, the trackball is required.  You can open the menu with the key and select items to menu with the first letter of the menu item and then hit enter, but you can not navigate to the screen without the trackball.

    Congratulations, these are probably the two most common questions in the forum. But do not usually get us together. First of all, not possible to switch to the video at all costs. I'm sorry. Computer laptop GPUS are hard soldered and uneditable except on a small handlful of laptops not including yours. Second, unless the laptop is deskbound for weeks in a row is not worth to take the battery out just to prolong her life.

    Yes, you should be able to work with power supply adapter only (if you have the battery removed).  It may be close for another reason.

  • after update of cc, I can't use photoshop cs6 without logging in cc.  Is there a way to get around this?

    after update of cc, I can't use photoshop cs6 without logging in cc.  Is there a way to get around this?

    I do nothing stored on the cloud, all work is local and I do not have to be connected.  It also seems to make Photoshop a LOT slower.

    Hello Christy,

    If it's a standalone Photoshop CS6 (ie you have a serial key) there is no need to connect to the desktop creative cloud application.

    If you have downloaded the 'previous Versions' CS6 creative cloud desktop application so you will need to stay connected on the creative cloud desktop application.
