• How to activate a button only when an item of component tilelist is selected

  Simple question, but it seems quite difficult for me. How to activate a button only when an item in a tilelist currently selected?

  For example, lets say if I have a button named button1, which is disabled by default and a tilelist component called tilelist1 that I should add in brackets the following (the enabled property of the button) code to make sure that the button is only enabled when an item in the tilelist component is currently selected but disabled when no item is selected :-

  enabled = "{}".

  Enabled = "{tilelist1. SelectedItem} ".

  that should do it, it is making an implicit comparison with null (tilelist1.selectedItem == null) which will result in a Boolean value.

  SelectedItem is null when nothing is selected, non-null when something is.

• How can I get rid of the box that appears when you start Firefox 'Restore previous Session'?

  How can I get rid of the box that appears when you start Firefox 'Restore previous Session'?

  Subject: House is the default in Firefox 4 home page - look at the address bar containing the addresses of web page - it is the container for Google search, with a 'extract container' and below these elements is the Previous Session Restore button. It's not the same homepage that previous versions of Firefox used (although it is similar in appearance), it is a 'local' page that won't load the Internet.

  Set this page as your home page, which is what Firefox 3.6 and earlier versions had for the default home page. He has Previous Session Restore button/link.

• How is it that some machines running windows vista, when the router is updated or changed, they show "limited or local only" when you reconnect then wireless.

  problems with wireless Vista "local only".

  How is it that some machines running windows vista, when the router is updated or changed, they show "limited or local only" when you then reconnect wireless... nothing else was changed on those computers and other devices can connect ok?

  Hello

  Each router is assigned to the specific address (called IP address or IP address). And each router maintains its own database (called as base of router) to follow the networking devices communicate with him. When the router is changed, the particular router is unable to detect the device, especially the network card to communicate with the computer.  Since he does not have details of the database of network devices, communicate with him.

• How to associate a browser with a new tab. When I click on the new tab, it's a blank page. I would like to a browser to load automatically into a new table.

  When I open a new tab, there is a blank page. I would like to a browser to load into a new tab, instead of having to click a browser after I opened the tab.

  Firefox and IE are web browsers, where Google and Bing are the search engines.

  By default, Firefox has a blank page when you open a new tab, which can be changed with a few different extensions.

  https://addons.Mozilla.org/en-us/Firefox/addon/NewTabURL/
  
  Place it just to any web page or a page of search engine as you want to see in a new tab.

• Problem with Internet connection - connect only after you turn off allowing then again.

  It is a recent problem that unfortunately I have very little information on. In other words, after months be happy and connection to the internet when you start the computer has decided he won't d more, instead he wants to deactivate and then activate the connection to the local network before it will connect.

  There is no error message and the convenience store could not find that something wrong then directed me here! I tried to diagnose too but didn't know what was wrong either. There are two computers connected through a router and the other is fine, ISP technical support assures me it's nothing to do with them either.

  It left me speechless. I tried the system restore, I crossed the two diagnoses available in internet options and I called ISP support. Although this isn't a direct threatening problem, it's one of those little niggles you want just leave.

  If anyone has any ideas on how to fix things, I'd be grateful.

  Hi tmaxwell83,

  1. did you of recent changes on the computer?

  2. do you have security software installed on the computer?

  3. What is the type of internet connection you use?

  This would happen if the NIC driver is corrupt or needs to be updated.

  I suggest that you install the updated drivers for the network adapter on the computer by visiting the network card or the computer manufacturer Web site, the check if it works fine.

• How to fix the text so it is not jumping when you type?

  I have Windows 7 on my Dell laptop.  When I type "anywhere" the characters jump all over the page, I type in.  How can I fix it?

  Hello Michele,

  A fairly common problem for laptops - its caused by the thumb, finger or palm (s) hit the Touchpad when you type. The infallible remedy only is an external mouse with Touchpad disabled. To do this, or just disable the Touchpad, go to control panel, select mouse properties and select the Touchpad tab in the top row of tabs.

  This will open an applet that allows you to select the order of Touchpad buttons, a check box parameter to disable the Touchpad when an external mouse is detected.  If you want faster access to this setting, make sure to display the icon in the system tray is also checked, and you will be able to access this setting in the notification area (bottom right of the task bar, click the arrow to access the Touchpad icon).

  To avoid problems to repeat in the future, make sure that if you go to Device Manager to "RID" the Touchpad you only disable the Touchpad as opposed to uninstall the Touchpad. If you uninstall the Touchpad, the next time you restart your computer, the applet will appear again back in place. You can only disable the Touchpad to get rid of him.

  Let me know if this solves the problem for you.

  Kind regards

• How to prevent a new tab in Firefox to open when you open a PDF file in Adobe.

  First of all, this problem started Monday, August 25, 2014 when I was forced to update Firefox to log in my accounting online program. I had no such problem in the previous version of Firefox.

  When I open a PDF document to an e-mail (which displays a Firefox icon next to it), the document opens in Adobe reader, but also a blank tab opens in Firefox, even with it is not already open. When I close the PDF, the Firefox tab remains open and I have to close it manually. Happening with PDF documents that I saved to the network of my company or my computer (which have the Adobe icon). I don't want to have to save a PDF file on my computer as a workaround for this problem.

  Under Tools > Options > Applications, I already spent the Adobe/PDF options to open it in Adobe. In addition, in topic: config, the value of 'pdfjs.disabled' reads 'true' and 'plugin.disable_full_page_plugin_for_types' contains "application/pdf".

  I work with a lot of PDF files and I'm frustrated to the point where I'm about to uninstall Firefox and just use Internet Explorer.

  Hello, it works when you enter in the Acrobat > edit > Preferences > General & click on the application by default option at the bottom? to reselect it adobe application and confirm this selection...
