  • refresh windows network performance counters in command line

    - by michalv82
    I am testing a USB device connected to a windows PC. When the device is connected then windows has another network interface going through the device. I need to get the bytes transffered for that specific interface, basically I need the data shown in the networking tab in the task manager for my interface adapter. I found this question which helped to get this info: ms windows network activity bytes send and receive in command line However I have a problem when I run multiple tests - each time I disconnect and connect the device there's another line for the interface, like below. In the task manager networking tab I only see one record for my interface but I don't know how I can know from command line which is the lastest and current instance (it's not like the first line or last line is always the current interface, I noticed it's not consistent): wmic path Win32_PerfRawData_Tcpip_NetworkInterface Get Name,PacketsReceivedPerSec,PacketsSentPerSec,BytesReceivedPersec,BytesSentPersec BytesReceivedPersec BytesSentPersec Name PacketsReceivedPersec PacketsSentPersec 422666370 6317989292 Intel[R] 82579LM Gigabit Network Connection 2715169 8109643 49150 375973 My USB Device 432 568 0 0 My USB Device _2 0 0 0 0 My USB Device _3 0 0 0 0 My USB Device _6 0 0 0 0 Local Area Connection* 9 0 0

  • Separating logic and data in browser game

    - by Tesserex
    I've been thinking this over for days and I'm still not sure what to do. I'm trying to refactor a combat system in PHP (...sorry.) Here's what exists so far: There are two (so far) types of entities that can participate in combat. Let's just call them players and NPCs. Their data is already written pretty well. When involved in combat, these entities are wrapped with another object in the DB called a Combatant, which gives them information about the particular fight. They can be involved in multiple combats at once. I'm trying to write the logic engine for combat by having combatants injected into it. I want to be able to mock everything for testing. In order to separate logic and data, I want to have two interfaces / base classes, one being ICombatantData and the other ICombatantLogic. The two implementers of data will be one for the real objects stored in the database, and the other for my mock objects. I'm now running into uncertainties with designing the logic side of things. I can have one implementer for each of players and NPCs, but then I have an issue. A combatant needs to be able to return the entity that it wraps. Should this getter method be part of logic or data? I feel strongly that it should be in data, because the logic part is used for executing combat, and won't be available if someone is just looking up information about an upcoming fight. But the data classes only separate mock from DB, not player from NPC. If I try having two child classes of the DB data implementer, one for each entity type, then how do I architect that while keeping my mocks in the loop? Do I need some third interface like IEntityProvider that I inject into the data classes? Also with some of the ideas I've been considering, I feel like I'll have to put checks in place to make sure you don't mismatch things, like making the logic for an NPC accidentally wrap the data for a player. Does that make any sense? Is that a situation that would even be possible if the architecture is correct, or would the right design prohibit that completely so I don't need to check for it? If someone could help me just layout a class diagram or something for this it would help me a lot. Thanks. edit Also useful to note, the mock data class doesn't really need the Entity, since I'll just be specifying all the parameters like combat stats directly instead. So maybe that will affect the correct design.

  • Centos OS resource footprint vs Ubuntu package refresh

    - by webworm
    I am trying to determine which distro to sink my teeth into. I am new to the Linux world and would like to choose a distro to focus on. I have read that CentOS uses less resources than Ubuntu, which is an issue for me since I am renting a VPS and resource cost is an issue. I have also read that Ubuntu has more up-to-date packages which is a concern for me as I want to use PHP and some packages that have a fair amount of dependencies. I am not using Linux as a desktop OS, rather just as a server for Apache, PHP, PERL, and Java development. What would be the best choice for a server OS? CentOS or Ubuntu? Are the resource requirements that different? Are the packages that different between the two? Thanks.

  • Updates to Silverlight Code Browser

    A couple of bits of news. I did a number of updates to the HackingSilverlightCodeBrowser here:http://www.hackingsilverlight.net/HackingSilverlightCodeBrowser.html including things like MEF and IsolatedStorage. As to the community edition of the book, I'm still trying to get some contributors to finish. I've been slammed with 60 hour weeks so chapter 2 and 4 and appendix a still need edits. maybe a weeks worth of work pending time which tends to be limited in my life. :)...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • How to Stop Browser from rejecting my downloads

    - by melki0795
    I have a portfolio site where I am trying to host some of my work, so people can download my work. Some of these files include exe executables, and some are jar executables, which are run through batch. When a user tries to download my apps, it says that the file is not commonly downloaded and may be harmful, and therefore blocks the download. If I zip the folders, it still does the same thing. Any format i choose, still blocks the downloads. How can I stop chrome from doing this. Is there a way I can verify my files so they will be considered as trusted? Thanks in advance!

  • Network/browser issues after upgrade to 12.04

    - by Reg
    I let my laptop upgrade to 12.04. And have no network afterwards. I went through all the articles I could find in google. Right now, I can ping google, and yahoo, but not cnn.com for example or anything else. Firefox says it can't reach google.com or gmail.com (or anything, not even IP. /etc/network/interfaces dns-nameservers 8.8.8.8 <<<<<added auto lo iface lo inet loopback /etc/dhcp/dhclient.conf #prepend domain-name-servers 8.8.8.8,8.8.4.4; prepend domain-name-servers 127.0.0.1; <<<<< tried both /etc/NetworkManager/NetworkManager.conf with and without dns=dnsmasq commented out. I can ping my wireless router and connect to it just fine. Have tried proxy/noproxy. This looks like After Upgrade to 12.04 - cannot connect to network but no answer there. I would hate to do a fresh install. Any assistance appreciated.

    I ran across these suggested htaccess edits. Is this a good practice?

  • How to start a local server and open it in a browser from a shell script

    - by davidchambers
    I have a test suite which runs in a browser (using QUnit, though that's unimportant). The test suite requires a local server running on a particular port. Running the tests currently involves a few steps: node test/server switch to browser of choice open localhost:3000 I'd like to have a single command which starts the server then runs open localhost:3000. Ideally, the node process would remain in the foreground so it could be killed with ^C. I don't have a good understanding of subshells, so I'm not sure whether this is possible.

  • Display on secondary video card (Nvidia 8400 GS): horrible refresh, bogs system

    - by minameismud
    This is my work computer, but it's a small shop. We do business software development. The most hardcore thing we create is some web animations with html5 and fancy javascript/css. The base machine is a Dell Precision T3500 - Xeon W3550 (3.07GHz quad), 6GB ram, pair of 500GB harddrives, and Win 7 x64 Enterprise SP1. My primary video card is an ATI FirePro V4800 1GB in a PCIe slot of some speed driving a pair of 23s at 1920x1080 through DisplayPort-HDMI adapters. The secondary card is an NVidia GeForce 8400GS in a PCI slot driving a single 17" at 1280x1024 through DVI. On either of the 23" monitors, windows move smoothly, scroll quickly, and are generally very responsive. On the 17", it's slow, chunky, and when I'm trying to scroll a ton of content, Windows will occasionally suggest I drop to the Windows Basic theme. I've updated drivers for both cards, and I've gotten every Windows update relating to video. Specifically: ATI FirePro Provider: Advanced Micro Devices, Inc Date: 6/22/2014 Version: 13.352.1014.0 NVidia 8400 GS Provider: NVIDIA Date: 7/2/2014 Version: 9.18.13.4052 Unfortunately, new hardware isn't really an option. Is there anything I can do software-wise to speed up the NVidia-driven monitor?

  • treeview loses data when page is being refreshed in asp.net

    - by Greg
    Hi, I have a treeview and I written a code for his "treeNodePopulate" event: protected void ycActiveTree_TreeNodePopulate(object sender, TreeNodeEventArgs e) { if (Application["idList"] != null && e.Node.Depth == 0) { string[] words = ((String)Application["idList"]).Split(' '); // Yellow Card details TreeNode child = new TreeNode(""); // Go over all the yellow card details and populate the treeview for (int i = 1; i < words.Length; i++) { child.SelectAction = TreeNodeSelectAction.None; // Same yellow card if (words[i] != "*") { // End of details and start of point ip's if (words[i] == "$") { // Add the yellow card node TreeNode yellowCardNode = new TreeNode(child.Text); yellowCardNode.SelectAction = TreeNodeSelectAction.Expand; e.Node.ChildNodes.Add(yellowCardNode); child.Text = ""; } // yellow card details else { child.Text = child.Text + words[i] + " "; } } // End of yellow card else { child.PopulateOnDemand = false; child.SelectAction = TreeNodeSelectAction.None; // Populate the yellow card node e.Node.ChildNodes[e.Node.ChildNodes.Count - 1].ChildNodes.Add(child); TreeNode moveChild = new TreeNode("Move To Reviewed"); moveChild.PopulateOnDemand = false; moveChild.SelectAction = TreeNodeSelectAction.Select; e.Node.ChildNodes[e.Node.ChildNodes.Count - 1].ChildNodes.Add(moveChild); child = new TreeNode(""); } } Application["idList"] = null; } } I want the treenode to get the data from the Application variable and then nullify the Application variable so that the tree will take data from Applcation only if there is something in it (I put data into the application from another page and then redirect to this page) But when I refresh this page the data in the treenode isnt being saved. I mean after the refresh the Application is null so he isnt doing anything. The question is why is the data that I put in the treenode earlier isnt being saved? The "enableViewState" property is set to "true".. Thanks in advance, Greg

  • How to clear wxpython frame content when dragging a panel?

    - by aF
    Hello, I have 3 panels and I want to make drags on them. The problem is that when I do a drag on one this happens: How can I refresh the frame to happear its color when the panel is no longer there? This is the code that I have to make the drag: def onMouseMove(self, event): (self.pointWidth, self.pointHeight) = event.GetPosition() (self.width, self.height) = self.GetSizeTuple() if (self.pointWidth>100 and self.pointWidth<(self.width-100) and self.pointHeight < 15) or self.parent.dragging: self.SetCursor(wx.StockCursor(wx.CURSOR_SIZING)) """implement dragging""" if not event.Dragging(): self.w = 0 self.h = 0 return self.CaptureMouse() if self.w == 0 and self.h == 0: (self.w, self.h) = event.GetPosition() else: (posw, posh) = event.GetPosition() displacement = self.h - posh self.SetPosition( self.GetPosition() - (0, displacement)) else: self.SetCursor(wx.StockCursor(wx.CURSOR_ARROW)) def onDraggingDown(self, event): if self.pointWidth>100 and self.pointWidth<(self.width-100) and self.pointHeight < 15: self.parent.dragging = 1 self.SetCursor(wx.StockCursor(wx.CURSOR_ARROW)) self.SetBackgroundColour('BLUE') self.parent.SetTransparent(220) self.Refresh() def onDraggingUp(self, event): self.parent.dragging = 0 self.parent.SetTransparent(255) self.SetCursor(wx.StockCursor(wx.CURSOR_ARROW)) and this are the binds for this events: self.Bind(wx.EVT_MOTION, self.onMouseMove) self.Bind(wx.EVT_LEFT_DOWN, self.onDraggingDown) self.Bind(wx.EVT_LEFT_UP, self.onDraggingUp) With this, if I click on the top of the panel, and move down or up, the panel position changes (I drag the panel) to the position of the mouse.

  • Memory leak on CollectionView.View.Refresh

    - by Dabblernl
    I have defined my binding thus: <TreeView ItemsSource="{Binding UsersView.View}" ItemTemplate="{StaticResource MyDataTemplate}" /> The CollectionViewSource is defined thus: private ObservableCollection<UserData> users; public CollectionViewSource UsersView{get;set;} UsersView=new CollectionViewSource{Source=users}; UsersView.SortDescriptions.Add( new SortDescription("IsLoggedOn",ListSortDirection.Descending); UsersView.SortDescriptions.Add( new SortDescription("Username",ListSortDirection.Ascending); So far, so good, this works as expected: The view shows first the users that are logged on in alphabetical order, then the ones that are not. However, the IsLoggedIn property of the UserData is updated every few seconds by a backgroundworker thread and then the code calls: UsersView.View.Refresh(); on the UI thread. Again this works as expected: users that log on are moved from the bottom of the view to the top and vice versa. However: Every time I call the Refresh method on the view the application hoards 3,5MB of extra memory, which is only released after application shutdown (or after an OutOfMemoryException...) I did some research and below is a list of fixes that did NOT work: The UserData class implements INotifyPropertyChanged Changing the underlying users collection does not make any difference at all: any IENumerable<UserData as a source for the CollectionViewSource causes the problem. -Changing the ColletionViewSource to a List<UserData (and refreshing the binding) or inheriting from ObservableCollection to get access to the underlying Items collection to sort that in place does not work. I am out of ideas! Help? EDIT: I found it: The Resource MyDataTemplate contains a Label that is bound to a UserData object to show one of its properties, the UserData objects being handed down by the TreeView's ItemsSource. The Label has a ContextMenu defined thus: <ContextMenu Background="Transparent" Width="325" Opacity=".8" HasDropShadow="True"> <PrivateMessengerUI:MyUserData IsReadOnly="True" > <PrivateMessengerUI:MyUserData.DataContext> <Binding Path="."/> </PrivateMessengerUI:MyUserData.DataContext> </PrivateMessengerUI:MyUserData> </ContextMenu> The MyUserData object is a UserControl that shows All properties of the UserData object. In this way the user first only sees one piece of data of a user and on a right click sees all of it. When I remove the MyUserData UserControl from the DataTemplate the memory leak disappears! How can I still implement the behaviour as specified above?
