• Software disables itself when the PC is accessed via RDP

  - by blckgrffn

  We have a large, specialty printer that has vendor specific software that enables its use outside of it showing up simply as a printer in the Windows Control Panel. This software recognizes when we RDP into the machine and "disconnects" the PC from the printer within its proprietary control panel. All is well when an application like TeamViewer is used to access the machine. Ostensibly, the application is helping us be safe by "enforcing" that the machine used for the printer is a walk up workstation, or so the support folks informed me. If TeamViewer etc, fixes the issue, then what is the problem? We have many headless workstations in our warehouse attached to a variety of specialty machines, all used via RDP. We want/need to keep access to the machines the same for the sanity of our production staff. The meat of the question - how, specifically, might a machine know that it is being accessed via RDP (terminal services management???) and how might this be defeated without altering an application or driver. Of note, the system being used is a Windows 7 Pro machine hooked to the printer via USB. Thanks! Nat edit Is there any combination of /admin switches, etc. that will possibly fix this? Simply putting /admin did not.

• Cannot browse Visual SVN Repositories

  - by user1783560

  I went through Unable to browse repository after setting visual SVN Server and tried to implement the answer suggested but even the IP address is not solving my problem. I have 1) Turned off firewall 2) Set the directory C:\Program Files (x86)\VisualSVN Server security rights to "full control" for all groups including "Network service" group. 3) Set the directory D:\Repositories security rights to "full control" for most groups including "Network service" group. 4) Tried switching between secure and non-secure connection option in visual svn server manager. 5) Tried different with port numbers. Including 443 (with https) and 80 (http). Also tried giving random ports with/without https. Using computer name/ IP address in the url doesn't help. Windows network diagnostics - Troubleshooting report has following message for me. Security policy settings or firewall settings on this computer might be blocking the connection. = Detected Can someone guide me please? I have spent more than two weeks on this now without any solution. Thanks in advance! I appreciate your responses.

• Git workflow for two tight-knit projects

  - by Pioul

  Two very similar projects I'm maintaining an online Markdown editor using Git as RCS (and accessorily made available on GitHub). From this web app, I've created a Chrome app: the code is the same, aside from some Chrome technicalities. I care about open sourcing these two projects. Still, the Chrome app's code being the same as the web app's except for some dull details, I've first chosen to (1) not publish the Chrome app on GitHub, and (2) not use Git to manage its code. Instead, I would manually review the web app's commits, then replicate the few changes in the Chrome app. … slightly drifting apart However, I've decided to add a feature to the Chrome app only. So, even though both codebases will remain broadly similar, they'll be diverging enough to make me reconsider the rationale behind my initial decision to not version control nor share the Chrome app's source code. Since I'm now willing to use Git to version control both apps, and that I want to share both of them on GitHub, how should I go about it? Should I use two different repositories, or one repo with two long-running branches? What would be the pros and cons of each approach in that context? What would be the easiest/fastest way to regularly "import" commits from the web app to the Chrome app, since the web app is going to remain the master branch? Is cherry-picking the only solution?

• What are the ways to build a failover cluster?

  - by light

  I have a task where I need to build a failover cluster in two cases: first with servers on Red Hat Enterprise 5.1 and second with SUSE Linux Enterprise 11 SP1. Both cases have SAN. I know there are many ways to build failover cluster, but I can’t find out more, so I need next: The ways to build it? I know only virtualization. Any good book or resource to broad my mind? I’ll be glad to hear any suggestion. Thanks! EDIT #1: failover of servers with bussiness application on it. EDIT #2: will be great to hear summary about solutions with SLES servers? EDIT #3: So if I understand correctly, in my cases the main ways are to use internal solutions or virtualization. So now I have additional questions: Does manufacturer of blades provide some solution? For example HP or IBM. (Without virtualization) Do I need additional server to control "heartbeat" between main and redundant servers? (Virtualization) For example I have several physical servers with VMs. Do I need additional server to control availability of VMs and to move VMs to another physical server in the case their physical server failure? Sorry for my poor English. EDIT #4: Failover of VM or OS on physical server. In both cases will be used SAN , it's not specified, but I think with file system image on it. I started to think that my question is stupid and I need to remake it.

• Access denied when trying to open files/folders after reinstall [closed]

  - by user711532

  Possible Duplicate: Access Denied when saving a file in Windows 7 I installed Windows 7 fresh on a new machine. Now when I unarchive (winrar or 7z etc. ) to Program files (x86) (for example), access denied. Even if I copy a file to a folder I installed an app to it is still access denied. I checked the security, it looks like full control is given to the creator - this is weird as I never ran across this before (same version of Windows 7 - its just a fresh install after some new hardware). It is the same effect as if I was editing the hosts file, and you do not use "run as admin" you will not be able to save it, yo will have to save it somewhere else. This "file copy" issue I ran into is the same. I could change all these permissions, however this is something I never had to do before. I am the admin, why did the install, not give me "full control"? How can this be globally fixed. I cannot change the permissions - they are greyed out - so that is weird as well. If I was a standard reason, It would make sense, however, again, I am the admin.

• What could be causing windows to fail to sleep or hibernate, and revert system settings?

  - by xdumaine

  I am running Windows 8.1 on my system (Dell e6520) and the symptoms are this: My PC won't sleep or hibernate. It the screen turns off, but the fans just run and run, and after a little while, it completely shuts down, and when I start it back up, everything is closed, like it was a fresh boot/restart. I'm have a weird issue with outlook described here and the fix works fine - modifying a registry value. The weirder part is that after my computer fails to sleep or hibernate, and it starts back up, the registry value is GONE, like I never modified it, and thus the outlook error message is back. I thought maybe a graphics driver was preventing the sleep/hibernate, so I attempted to uninstall the NVIDIA graphics driver and control panel. HOWEVER, once the computer fails to sleep/hibernate, the NVIDIA graphics driver and control panel appear BACK on my system, like I didn't uninstall them. What could be happening here? I really need to be able to sleep/hibernate so I don't lose work or my work state, and these issues are really concerning. What I've tried, without success: Uninstalling graphics driver mentioned above Disabling hibernate and using sleep disabling/re-enabling hibernate Disabling startup items Sleeping as local system admin account disconnecting all USB, network, and bluetooth devices

• Drag and Drop in MVVM with ScatterView

  - by Rich McGuire

  I'm trying to implement drag and drop functionality in a Surface Application that is built using the MVVM pattern. I'm struggling to come up with a means to implement this while adhering to the MVVM pattern. Though I'm trying to do this within a Surface Application I think the solution is general enough to apply to WPF as well. I'm trying to produce the following functionality: User contacts a FrameworkElement within a ScatterViewItem to begin a drag operation (a specific part of the ScatterViewItem initiates the drag/drop functionality) When the drag operation begins a copy of that ScatterViewItem is created and imposed upon the original ScatterViewItem, the copy is what the user will drag and ultimately drop The user can drop the item onto another ScatterViewItem (placed in a separate ScatterView) The overall interaction is quite similar to the ShoppingCart application provided in the Surface SDK, except that the source objects are contained within a ScatterView rather than a ListBox. I'm unsure how to proceeded in order to enable the proper communication between my ViewModels in order to provide this functionality. The main issue I've encountered is replicating the ScatterViewItem when the user contacts the FrameworkElement.

• Binding the position and size of a UserControl inside a Canvas in WPF

  - by John

  Hi. We have dynamically created (i.e. during runtime, via code-behind) UserControls inside a Canvas. We want to bind the position (Canvas.Left and Canvas.Top) and width of those sizable and draggable UserControls to a ObservableCollection<. How would we achieve this if the Usercontrol is contained in a DataTemplate which in turn is used by a ListBox whose DataContext is set to the collection we want to bind to? In other words, how do we bind a control's position and size that doesn't exist in XAML, but in code only (because it's created by clicking and dragging the mouse)? Notice that the collection can be empty or not empty, meaning that the size and position stores in a collection item must be correctly bound to so that the UserControl can be sized and positioned correctly in the Canvas - via DataBinding. Is this possible?

• User.IsInRole returning false

  - by Curtis

  My ASP.NET app is using windows authentication. If I run the following code: WindowsIdentity wi = (WindowsIdentity)User.Identity; foreach (IdentityReference r in wi.Groups) { ListBox1.Items.Add(r.Translate (typeof (NTAccount)).Value); } if (User.IsInRole ("Everyone")) Label1.Text = "Is in role"; The listbox will contain the name of every group the user belongs to. If I then call User.IsInRole, and pass in the name of any of those groups, I always get a false. Can anyone tell me what I am doing wrong? Thanks

• Why is WPFToolkit DataGrid so slow when binding?

  - by Schneider

  I have a very simple test application where I have two objects, each with a small collection of items. when I select an object I display its collection in a WPFToolkit DataGrid. The problem is there is a noticeable delay, such that if you press up/down keys to toggle selection between objects you can see it can't keep up. Why is the performance so bad? <Window x:Class="SlowGridBinding.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Controls="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit" Title="MainWindow" Height="350" Width="525"> <StackPanel> <ListBox ItemsSource="{Binding Shops}" DisplayMemberPath="Name" IsSynchronizedWithCurrentItem="True"/> <Controls:DataGrid ItemsSource="{Binding Shops/Vegetables}" AutoGenerateColumns="True"/> </StackPanel> The DataContext is populated with some test classes filled with 50 items of random test data.

• WPF - Virtualizing an ItemsControl?

  - by Rachel

  I have an ItemsControl containing a list of data that I would like to virtualize, however VirtualizingStackPanel.IsVirtualizing="True" does not seem to work with an ItemsControl. Is this really the case or is there another way of doing this that I am not aware of? To test I have been using the following block of code: <ItemsControl VirtualizingStackPanel.IsVirtualizing="True" ItemsSource="{Binding Path=AccountViews.Tables[0]}"> <ItemsControl.ItemTemplate> <DataTemplate> <TextBlock Initialized="TextBlock_Initialized" Margin="5,50,5,50" Text="{Binding Path=Name}" /> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> If I change the ItemsControl to a ListBox, I can see that the Initialized function only runs a handful of times (the huge margins are just so I only have to go through a few records), however as an ItemsControl every item gets initialized. I have tried setting the ItemsControlPanelTemplate to a VirtualizingStackPanel but that doesn't seem to help.

• Databinding gives "System.Data.DataRowView" instead of actual values

  - by iTayb

  This is my code: string SQL = "SELECT email FROM members WHERE subscribe=true"; string myConnString = Application["ConnectionString"].ToString(); OleDbConnection myConnection = new OleDbConnection(myConnString); OleDbCommand myCommand = new OleDbCommand(SQL, myConnection); myConnection.Open(); OleDbDataAdapter MyAdapter = new OleDbDataAdapter(myCommand); DataSet ds = new DataSet(); MyAdapter.Fill(ds); MailsListBox.DataSource = ds; MailsListBox.DataBind(); GridView1.DataSource = ds; GridView1.DataBind(); myConnection.Close(); And so it looks: As you see, the GridView shows the dataset just fine, and the ListBox fails it. What happened? How can I fix it? Thank you very much.

• WPF Show Open TabItem Names in a List View

  - by mr justinator

  I'm trying to display a list of open tab names in a listview or listbox (recommendations?). Been going through the different type of binding options and I'm able to bind to a single tab name but it displays vertical instead of horizontal. Here is my XAML: <ListView DockPanel.Dock="Left" Height="352" Name="listView1" Width="132" ItemsSource="{Binding ElementName=RulesTab, Path=Name}" IsSynchronizedWithCurrentItem="True" FlowDirection="LeftToRight" HorizontalAlignment="Left" HorizontalContentAlignment="Left" DataContext="{Binding}"> Any pointers would be greatly appreciated as I'd like to be able to see a list of all the tabs open and then double click on one to bring the tab into focus. Many thanks!

• .NET Thread Pool - Unresponsive WinForms UI

  - by Goober

  Scenario I have a Windows Forms Application. Inside the main form there is a loop that iterates around 3000 times, Creating a new instance of a class on a new thread to perform some calculations. Bearing in mind that this setup uses a Thread Pool, the UI does stay responsive when there are only around 100 iterations of this loop (100 Assets to process). But as soon as this number begins to increase heavily, the UI locks up into eggtimer mode and the thus the log that is writing out to the listbox on the form becomes unreadable. Question Am I right in thinking that the best way around this is to use a Background Worker? And is the UI locking up because even though I'm using lots of different threads (for speed), the UI itself is not on its own separate thread? Suggested Implementations greatly appreciated.

• Object Reference Error filling a datarow

  - by JPJedi

  This is the code: Dim dr() As DataRow = DataSet.Tables("TableName").Select("EVENTNAME = '" & name & "'") I get an "Object reference not set to an instance of an object." Error when this line is executed. It is looping through a list of selected items in a listbox. I think it has to do with how I have the datarow declared because I can look at the name and I see it ok and I also do a null check on the name before I use it. Visual Studio 2008, VB.NET. Any ideas? Yep it was a wrong table name. I guess after looking at the code for 8 hours that minor detail I just wasn't thinking to check. Thanks!

• how do i return arraylist from a function?

• A cross between std::multimap and std::vector?

  - by Milan Babuškov

  I'm looking for a STL container that works like std::multimap, but has constant access time to random n-th element. I need this because I have such structure in memory that is std::multimap for many reasons, but items stored in it have to be presented to the user in a listbox. Since amount of data is huge, I'm using list box with virtual items (i.e. list control polls for value at line X). As a workaround I'm currently using additional std::vector to store "indexes" into std::map, and I fill it like this: std::vector<MMap::data_type&> vec; for (MMap::iterator it = mmap.begin(); it != mmap.end(); ++it) vec.push_back((*it).second); But this is not very elegant solution. Is there some such containter?

• Are Inherited Forms And/Or Inherited Controls possible in Managed C++

  - by Ali Akdurak

  Hello everyone The question is actually pretty self explanatory but I will further clarify it. I am building a simple application to show a load [file] for 5 different types of [files]. So all these 5 forms will have similar GUI elements such as a listbox and a load button with a small textbox/label to show the summary of the [file]'s information. My desired effect is something like visual studio's C# template for Inherited User controls or Inherited forms. I already heavily googled the concept to look for a C++ visual studio template to the trick but I couldn't find it. The word [file] is in brackets because open file dialogue will not the trick as this list of files to select form comes form an SQL server. Thanks a lot!

• itunes sdk list albums

  - by Matt Facer

  Hi guys, I'm working on a new test app (just out of curiosity really) which is an add on to iTunes. I'm trying fairly basic things at the mo, and have managed to control volume, pause etc etc. I have a function from some demo code which loops through all the tracks in my main library and gets their album name... I then show the individual album name in my listbox. This is FAR from the best way to do it! Is there a way to query the library to get just the album names? I ultimately want to get to a point where I can have a list of albums (with images) - I click on the album name and that loads the associated tracks.... thanks for any help! (I'm using VB.net btw)

• Binding list of objects to WPF ListView

  - by Dave Colwell

  Hi all, I have a list of objects which i want to bind to a ListView control in my WPF application. The Objects have a DataTemplate already, so no need to define that. The list of objects is a property in the codebehind file in the format list<object> When i add one object programatically, it appears fine. But when i try to bind the ItemSource of the ListBox to the list of objects, nothing shows up. I am using the following binding: ItemsSource="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=Portfolios}" where the name of the property i am trying to bind to is Portfolios and exists on the parent window

• Kendo UI, searchable Combobox

  - by user2083524

  I am using the free Kendo UI Core Framework. I am looking for a searchable Combobox that fires the sql after inserting, for example, 2 letters. Behind my Listbox there are more than 10000 items and now it takes too much time when I load or refresh the page. Is it possible to trigger the sql query only by user input like the autocomplete widget do? My code is: <link href="test/styles/kendo.common.min.css" rel="stylesheet" /> <link href="test/styles/kendo.default.min.css" rel="stylesheet" /> <script src="test/js/jquery.min.js"></script> <script src="test/js/kendo.ui.core.min.js"></script> <script> $(document).ready(function() { var objekte = $("#objekte").kendoComboBox({ placeholder: "Objekt auswählen", dataTextField: "kurzname", dataValueField: "objekt_id", minLength: 2, delay: 0, dataSource: new kendo.data.DataSource({ transport: { read: "test/objects.php" }, schema: { data: "data" } }), }).data("kendoComboBox"); </script>

• WPF Binding Collection To ComboBox and Selecting an item

  - by Adam Driscoll

  I've been knocking my head against this for some time now. I'm not really sure why it isn't working. I'm still pretty new to this whole WPF business. Here's my XAML for the combobox <ComboBox Width="200" SelectedValuePath="Type.FullName" SelectedItem="{Binding Path=Type}" Name="cmoBox" > </ComboBox> Here's what populates the ComboBox (myAssembly is a class I created with a list of possible types) cmoBox.ItemsSource = myAssembly.PossibleTypes; I set the DataContext in a parent element of the ComboBox in the code behind like this: groupBox.DataContext = listBox.SelectedItem; I want the binding to select the correct "possible type" from the combo box. It doesn't select anything. I have tried SelectedValue and SelectedItem. When I changed the DisplayMemberPath of the ComboBox to a different property it changed what was displayed so I know it's not completely broken. Any ideas???

• Access Elements inside a DataTemplate... How to for more than 1 DataTemplate?

  - by GaaTY

  I've got 2 DataTemplates defined for a Listbox Control. 1 Template is for the UnSelected State and the other one is for the Selected State(showing more detail than the UnSelected State). I followed the example here: http://blogs.msdn.com/b/wpfsdk/archive/2007/04/16/how-do-i-programmatically-interact-with-template-generated-elements-part-ii.aspx about how to access the Elements inside the DataTemplates from Code behind. I get it right, but it only finds and returns an element of the UnSelected DataTemplate. But when i search for an element in the Selected DataTemplate i get a NullReferenceException. What could i be doing wrong?
