How can I restore manage networks wireless in the Panel?

Kept losing the connection Wireless on my wife's computer.  Try to fix on my side and suddenly discovered the "manage wireless connections" option was missing control panel "Network and sharing Center."  Anyone knows how I can get it back?  Tried the system restore, but still get an error message telling me I can't restore my system, etc.  In fact, I've never had a computer in which "System Restore" actually worked.  But I digress.  Someone tell me how to recover my options 'manage wireless connections', I'd appreciate it.  Thank you.

  • How can I display table 2D tabular on the Panel before the user can delete any subdashboards

    Hi guys and girls.

    It is my first post here, so go easy on me. I promise you that I used my best GoogleFu I before posting here.

    I am a self taught amateur LabView. I worked on a User Interface for my Robot SAGAR. See some of my work so far (girlfriend used as a draft classes, but we have both worked together on it, which got hooked me in the first place on LV):

    Now, I'm working on the use of LV and Google Earth as a planner of mission right now.

    My question is this. I have a 2D array that stores the Lat/Lon each waypoint. I's like to have posted on my

    front tabular, with WP # (the 1st dimension array index), Lat and Lon on line, like this.

    More importantly, have the user can select a point of full path (or just the number of WP would be ok) and remove it using key DELETE or any other button on the Panel.

    I am at a loss on how to do it. Ideas?

    Thanks for the help!

    Heal the little robot.

    You said that you were using a table. I suggest using a multicolumn listbox. In this way, you can change the selection mode to "highlight the whole line. You can use a structure of the event to respond to the user by pressing the delete key. See attached simple example. Note that some keyboard can label the BACKSPACE key as 'delete '. If you want to answer it, you also have to see if the Char value is 8, which is the code for this key.

    [Moved from comments]

    There are some patches for the issue that you siding, but most of them requires registry changes that I do not say that they can cause several other problems. I recommend that you perform a system restore.

    There are two ways to perform the system restore:

    Menu start open, click Run and type cmd to open the command prompt.

    Type CD... to book only c:\.

    Type windows CD then CD System32, and then restore.

    After once, you'll find yourself in c:\ windows\system32\restore >

    Type restrui.exe press ENTER.

    Once the system restore the open window then click on next to select any available restore point.

    This process takes a few minutes to do the restore and please make sure that once this process has begun there wont be reversible and or you will lose all personal data.

    Another way to perform the system restore is to open the safe mode by clicking on F8 at startup and check the option of safe mode, then still a dialog box opens to ask the system restore and then follow the steps above.

  • How can I restore Favorites after migration to the cloud?

    This weekend, we migrated our computer system in the cloud. I was under the assumption that we were only migrate our email to the cloud.

    However, when I got to the office yesterday, I have Firefox was longer on my computer and subsequently were my favorites.

    I looked at a multitude of messages and what is seen on the fact that all is lost. I looked at the files on the C: drive and the only thing that is in these folders are what I did yesterday and today. Is it all the same to find my data from last Friday?

    Thank you
    Mike

    "This weekend we migrated our computer system in the cloud."

    What was the purpose of the 'us' who did this?
    That allows you to save the user data for the purposes of upgrading a server or software on the server?
    Each user backup up to their own data, or was this fact for all users massively by the COMPUTER service company?
    Whatever it is, you have access to the saved data in the "cloud"?
    If not you personally, IT department access to these data and restore?

    Overall, my guess is that your Firefox data has not been saved then your user account on a shared central server has been deleted or "gone" due to a system upgrade. And then when the user accounts have been restored data Firefox wasn't there.
    Shear speculation on my part, without much more information on what has been done.

Can I add them to the swatch main group so that they are always available for each new document, and so that the swatch group "remembers" that which has been used where?
