  • How to Update TreeViewItem's IsExpanded property to false in code behind?

    - by viky
    I am working with WPF TreeView control. I am creating a hierarchical data structure and assigning it to ItemsSource and it will generate TreeviewItems automatically. By default I use IsExpanded of TreeViewItem to true. But in a particular case, I want to set IsExpanded property to false. So that treeview loading doesn't take time to generate all items. How can I set that in code since I don't have reference to TreeViewItem's instance at that time?

  • I can't get my Android program to run correctly on an AVM in Eclipse

    - by Wes
    This is a simple question about getting started with developing Android apps using Eclipse. I have followed all the tutorials on the developer site for installing Eclipse, the SDK and the ADT plugin. When trying to run a simple Hello World program, everything seems to compile correctly, but then the virtual machine comes up empty. In the Console Window it reads: The program then just sits and my text never comes up. Any idea with what the problem could be?

  • Ubuntu crashed, Eclipse lost .metadata, Java Perspective gone, missing, lost

    - by Stewart
    I am running Eclipse Galileo on Ubuntu 10.04 LTS. Ubuntu crashed on me today, and after rebooting, I found that Eclipse has completely lost the Java Perspective (it's like the perspective and all associated views never existed) and the .metadata dir in my workspace is empty except for version.ini. What's up with that? Why did it happen? How can I prevent it? How can I recover from it?

  • Invisible sprites still take up a lot in memory

    - by numerical25
    Just curious, if I have a sprite on the stage with the alpha set to 0 does that take up just as much memory as a sprite that is visible? I imagine it does because it draws the sprite to the stage and then it has to set the alpha to zero. It may seem like a stupid question but I just wanted to verify.

  • PHP: Over-writing session variables

    - by Tom
    Hi, Question related to PHP memory-handling from someone not yet very experienced in PHP: If I set a PHP session variable of a particular name, and then set a session variable of the exact same name elsewhere (during the same session), is the original variable over-written, or does junk accumulate in the session? In other words, should I be destroying a previous session variable before creating a new one of the same name? Thank you.

  • Inserting Strings Without Trailing Spaces SQL

    - by Soo
    I have a database with a field named Field1 that has 100 nchars per entry. Each time I add a value, it is stored as: "value (100-ValueLength Spaces) " So Basically each stored value has a string of spaces after it. This is getting to be an issue when I try doing: if (value == "Example") because of all of the empty spaces after the string. How can I get it so the stored values don't have all of these trailing spaces?

  • Uninstalled server 2008 now router won't handle DHCP

    - by john
    My set up is this. server behind router, router has a server and switch connected to it with multiple computers. router used to serve DHCP and DNS, a couple of days ago installed AD, DNS and DHCP on the server, and the server gave out IP's. For various reasons we had to uninstall the domain on our server. I removed AD, DHCP and DNS from the roles and set the router back to serving DHCP and DNS. Now I can't get computers on the network. I reset my router back to factory defaults, and if I plug a computer directly into the router I can get a IP address, but all the computers behind the switch can't get an IP address and can't see the router. All my computers say unidentified network, and if I ping the router it says host is unreachable. On the other hand, my wireless devices are just fine and connect no problem. But for desktops, ipconfig /release doesn't release anything and /renew can't find a server to renew on. My router log shows several FIN scans but they are from innocuous websites (google, netgear) and it shows a couple of smurf attacks but they are all from my external IP. Any ideas? the server isn't even connected to the route right now, and all the computers are set for dynamic IP addresses.. I don't know what else to try? Any help?
