XControl always locked when it is used in class - possible bug?
Hello
It is no different in this issue. However, I think the question is slightly different and maybe a bug. If the following steps:
- Create a project,
- create an XControl
- create a class,
- Add an instance of the XControl to a class method
You should see that the XControl is locked all the time. This happens only when the XControl is used with a class. If the XControl is placed on a VI, in a library project or not, the XControl will only be locked when the VI that he uses is open (i.e. in memory and the XControl is running).
It can be expected behaviours because of the way the classes are loaded; However, as a user I find that it is unexpected - is this a bug?
Kind regards
Steve.
Unlike normal libraries (.lvlib), classes always loading all their members live in memory when the class is loaded in memory. So if one of these screws using an XControl, then it will be blocked as soon as you load the class owner in memory, even if the VI is not open. You might be able to work around this problem by right-clicking the XControl in the project and selecting "unlock the library for editing. It would temporarily break any screws that call the XControl until you're done editing.

RE: Missing buttons when the publication to interactive PDF - possible bug?
Hello
Still having the following problem published last month - no matter who else has come across this:
I am creating a 12 page PDF interactive with a set of 12 buttons (defined in the master page) at the bottom of page that relates to each page. When you click on the button you should directly to this page.
I used this method several times before in CS5 to help get to destination in buttons and the definition of each page as a destination. It works fine normally.
However, in CS6 once I have export as interactive and open PDF in Acrobat Pro buttons that everything seems to disappear once you click the button on the 3rd or 4th page.
I stripped the indesign doc to include any other content - just the buttons, without effects of rollover etc, but I'm still having the same problem
Please can someone help? I can provide the relevant and exported indesign doc PDF if this can help.
UPDATE: A member of the forum tries to open it in Acrobat Reader instead and it worked fine. It's OK to a point, but I really need to open in Acrobat Pro.
It is a known problem and should be fixed in the next point press.

Since the last update of Firefox (Version 4.0.1) I do not see a security lock when I connect my two web sites to secure Bank so am forced to use Internet Explorer for internet banking. I contacted the St George Bank and the ANZ Bank and both say that the problem with Firefox, not their systems. They advise also strongly me to not perform Internet banking unless the security padlock closed is visible in the window secure. The padlock is not visible when I connect secure site of PayPal. Before the upgrade, this problem did not exist and there is no when I use IE. Firefox is my favorite browser.
The status bar everything has been redesigned, so now allows you to check if the site is secure the box to the left of the address (green, blue or plain).

Change "until published switch" "lock when released" type of trigger...?
I'm still pretty new for LV and I looked around trying to find a way to change my event trigger, but with no result... maybe the wisdom of the Board of Directors can give information me.
I have attached a VI that gives the basic idea of what I am working with two buttons and LEDS simulate the signal, I have another process. Basically, I have two relays that are opening or closing of a valve to maintian has set value and I'm counting the number of times, it goes from the opening to the closing if I can detect '' hunt '' (i.e. - my valve reacts more quickly than expected and about to set of shooting)
Relay loop signal is currently acting as I switches "switch Unitl out ' that sends a 'ping' event every time that the while exectutes, but I need the signal up to the counter to act as if I've changed the switches" lock when released "... y at - it a simple way to do this? Yet once, I looked in the forums and knowledge base, with no results... any pointers in the right direction would be much appreciated!
Thank you

Put your boot system helps determine if third-party applications or startup items are causing the problem. If so, you can go ahead and disable or uninstall the same.

Win7 always tries to connect by using the default profile for the Native WIFI
Win7 always tries to connect by using the default profile for the Native WIFII defined a new WIFI profile for my home WIFI network. I use a USB of NETGEAR WNA1100 adapter. The profile is configured to connect automatically. I also moved over the default profile for the Native WIFI. Win7 always tries to connect to the default Native WIFI profile and not the profile that I created. Also, when I restart Win7, the default profile for the native WIFI moves to the top of the Profiles list. Also, when I try to change the default Native WIFI profile to use security WPA2 - PSK (AES) instead of WEP, it allows me to make changes, but he comes back to WEP after it treats changes and attempts to connect to the network. How can I fix so that Win7 will use my profile to connect to my home WIFI network and not the Native WIFI as the default profile. Win7 still connect using the default profile of NativeWIFI despite installing a different profile in Control Panel 'Wireless Networks '. I know that I can edit this profile by default, but anyone know how tell Win7 to use a different profile than the default? I tried to change the positions of the profile so that I want to use is facing up, but no, still uses the default. If I try to remove it, it comes back.After removing the two profiles and adding the profile for my home network, Win7 automatically added the default profile for the return NativeWIFI. My profile is configured to automatically connect to the network using WPA2 - PSK (AES) security and the default profile for the NativeWIFI (use WEP security) is the Win7 Setup to manually connect. Also, Win7 puts the default profile for the NativeWIFI above my profile. Also, when I delete the profile by default the NativeWIFI, Win7 it always puts back and he goes over my profile. This is starting to resemble the Win7 manage wireless mechanism for allowing users to add and prioritize the profiles of school boards does not work. Here's another thing that happens: when I try to change the security for the profile default of NativeWIFI to WPA2 - PSK (AES) of WEP, Win7 allows me to make changes, but it is up to the WEP after it processes the changes and tries to connect to the network. This seems too much for me, it's a problem with Win7. If I could do this job, so I need not to set up a second profile.The adapter I use a NETGEAR WNA1100 works correctly and I use it without any problem. I have is with Win7 and the interface to 'manage wireless networks '. It will not honor the fact that the WIFI profile that I created for my home network must be connected to automatically I installed. He always wants to connect to the default profile NativeWIFI even if I set up my home network profile to connect automatically. I can do a manual connection for my home network without problem. It seems to me that it is a question of Win7.Kind regardsQRPThank you very much - Netgear seems to have finally accepted as the default network! If all goes well it will stay like this
