  • Logging Remote Desktop to Servers via Logon Script or GPO or What?

    - by Nate Bross
    The objective here is to start a simple .NET application I've written which captures some environment variables (time, username, computername, etc) upon login. This .NET application subscribes to the Windows "User logout" event. Upon launch, the application captures the above variables, and creates a record in my database, upon logout (which I'm capturing) I update another field in the same record, with the logout time. The above is working exactly as I would like, when I launch the binary, it makes its initial log entry, then waits for the logout event and updates the same record. Restrictions, the .NET binary should be able to live on a share point (\server\share\myapp\v1) so I can update the application to (\server\share\myapp\v2) and simply update the GPO/Logon script. My initial thought was to use the \domaincontroller\sysvol\ directory to store the binary and then update all user accounts to include a call to my application. Can you see any flaws in this approach? My question is this: First, is there anything wrong with my idea above? Second, if so, what is the best way (through group policy or otherwise) to ensure this application launches whenever a session is started on a server?

  • How to "FTP jail" with apache?

    - by Nate
    I need to allow someone access to my website via FTP, but there are a number of directories that the person must not be allowed to view or modify. For example, something like this: private_info_1 public_info_1 private_info_2 public_info_2 In this example, the FTP user would need to be allowed to do stuff in the public directories, but not the private ones. How do I go about doing this with an Apache server? I have cPanel and SSH access.

  • How can I make zsh completion behave like Bash completion?

    - by Nate
    I switched to zsh, but I dislike the completion. If I have 20 files, each with a shared prefix, on pressing tab, zsh will fully complete the first file, then continue going through the list with each press of tab. If I want one near the end, I would have to press tab many times. In bash, this was simple - press tab and I would get the prefix. If I continued typing (and pressing tab), bash would complete as far as it could be certain of. I find this behavior to be much more intuitive but prefer the other features of zsh to bash. Is there a way to get this style of completion? Google suggested setopt bash_autolist, but this had no effect for me (and no error message was printed upon starting my shell). Thanks.

  • In Ubuntu Linux, how do I list packages installed from the “universe” repository?

    - by Nate
    On an Ubuntu 10.04 LTS server, I want to list installed packages and see what repository they come from. It’s easy to list installed packages, but it does not include the name of the repository (such as “main” or “universe”). And this information isn’t in /var/lib/dpkg/status, so dpkg-query doesn’t show it either. I want to get a list of “unsupported” software—that is, software that doesn’t come from the “main” repository, and for which Ubuntu does not guarantee security updates. Note: This is a server. It does not have X, GNOME or KDE installed.

  • Add PRISM Region Manager In Existing Navigation Window

    - by Nate Noonen
    We have a "legacy" WPF applicaton that is based on a NavigationWindow. The NavigationWindow has a fairly large ControlTemplate that houses a ContentPresenter as so: <ControlTemplate> ....snip... <ContentPresenter x:Name="PART_NavWinCP" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"/> .....snip.... </ControlTemplate> What we want to do is use that ContentPresenter as the first tab and dynamically add other tabs at run time. Like this: <ControlTemplate> ....snip... <TabControl Background="Transparent" cal:RegionManager.RegionName="MainRegion" Grid.ColumnSpan="2" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"> <TabItem Header="Nav Window Content"> <ContentPresenter x:Name="PART_NavWinCP" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"/> </TabItem> </TabControl> .....snip.... </ControlTemplate> Then our Modules grab the RegionName and insert their content dynamically. The issue seems to be that the PRISM region manager doesn't like that our code is in a ContentTemplate and cannot resolve the region. I have tried updating the RegionManager, adding the Region dynamically, just having a root tab control without the ContentPresenter, but I cannot get this to work. Any ideas?

  • XNA Class Design with Structs

    - by Nate Bross
    I'm wondering how you'd recommend designin a class, given the fact that XNA Framework uses Struct all over the place? For example, a spite class, which may require a Vector2 and a Rectangle (both defined as Struct) to be accessed outside of the class. The issue come in when you try to write code like this: class Item { public Vetor2 Position {get; set;} public Item() { Position = new Vector2(5,5); } } Item i = new Item(); i.Positon.X = 20; // fails with error 'Cannot modify the return value of Item because it is not a variable.' // you must write code like this var pos = i.Position; pos.X++; i.Position = pos; The second option compiles and works, but it is just butt ugly. Is there a better way?

  • VS2010 Assembly Load Error

    - by Nate
    I am getting the following error when I try to build an ASP.NET 4 project in Visual Studio 2010: "Could not load file or assembly 'file:///C:\Dev\project\trunk\bin\Elmah.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515)". I have verified that the dll does, in fact, exist, and is getting copied to the bin folder correctly. I have also tried removing and then re-adding the reference to the project. The build only fails when I switch the Solution Configuration to "Release". It does not fail when the Solution Configuration is set to "Debug". The only difference between the two configurations (that I know of) is shown in the following Web.config transform, Web.Release.config: <?xml version="1.0"?> <configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform"> <connectionStrings> <add name="SqlServer" connectionString="" providerName="System.Data.SqlClient" xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/> </connectionStrings> <system.web> <compilation xdt:Transform="RemoveAttributes(debug)" /> <customErrors mode="On" xdt:Transform="Replace"> <error statusCode="404" redirect="lost.htm" /> <error statusCode="500" redirect="uhoh.htm" /> </customErrors> </system.web> </configuration> I have tried using Fusion Log Viewer to track down the assembly binding issue, but it looks like it is finding and loading the assembly correctly. Here is the log: *** Assembly Binder Log Entry (6/8/2010 @ 10:01:54 AM) *** The operation was successful. Bind result: hr = 0x0. The operation completed successfully.

  • Standard way to persist data between requests in ASP.NET-MVC

    - by Nate Bross
    What is the most standard or best way to persist data between requests? Should I use cookies or session variables? I'm interested in keeping data like sort order, sort column, and page number (for paginiation). I'm coming from a webforms background so normally this type of thing was automatically handled for me in the viewstate of the controls I was using.

  • C# - Close a child form from parent

    - by Nate Shoffner
    I have a parent form and a child form. I need to open the child form at the beginning of a method, do some pretty intensive tasks and then close the child form upon completion. Here is basically what I've tried so far (with no luck): Parent Form: Child child = new Child(); Method() { child.ShowDialog(); //Method code here child.CloseScan(); } Child Form: public void CloseScan() { this.Close(); }

  • Notepad++ IDL Syntax Highlighting?

    - by Nate
    I was about to create a user-defined language file for Notepad++ to syntax-highlight IDL. But before I went and spent the time creating one, I wanted to check with the "community" to see if anyone else has one that's ready to go. Does anyone have any suggestions?

  • PHP - Plus sign with GET query

    - by Nate Shoffner
    I have a PHP script that does basic encryption of a string through the method below: <?php $key = 'secretkey'; $string = $_GET['str']; if ($_GET['method'] == "decrypt") { $output = rtrim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, md5($key), base64_decode($string), MCRYPT_MODE_CBC, md5(md5($key))), "\0"); } if ($_GET['method'] == "encrypt") { $output= base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, md5($key), $string, MCRYPT_MODE_CBC, md5(md5($key)))); } echo $output; ?> An example of a URL to encrypt a string would look like this: Encrypt.php?method=encrypt&str=the quick fox Which would return this as the encrypted string: LCuT/ieVa6cl3/4VtzE+jd9QPT3kvHYYJFqG6tY3P0Q= Now to decrypt the string all you have to do is change the "method" query to "decrypt", like so: Encrypt.php?method=decrypt&str=LCuT/ieVa6cl3/4VtzE+jd9QPT3kvHYYJFqG6tY3P0Q= The only problem is that when that encrypted string is decrypted it returns this: ¬ƒ§rYV}̳5Äš·nßì(ñïX8Þ;b I have narrowed down the problem to the plus sign that is in the encrypted string. PHP's GET method seems to translate a plus sign into a blank space. I have searched this bug and found out that it has already been filed here. I have tried different methods listed on that page and others with no success. The closest I got is by using this: $fixedstring = str_replace(" ", "+", $string); and then using $fixedstring in the encryption methods, the problem is, upon decryption, all blank spaces are converted to plus signs. Any ideas?

  • WCF MessageHeaders in OperationContext.Current

    - by Nate Bross
    If I use code like this [just below] to add Message Headers to my OperationContext, will all future out-going messages contain that data on any new ClientProxy defined from the same "run" of my application? The objective, is to pass a parameter or two to each OpeartionContract w/out messing with the signature of the OperationContract, since the parameters being passed will be consistant for all requests for a given run of my client application. public void DoSomeStuff() { var proxy = new MyServiceClient(); Guid myToken = Guid.NewGuid(); MessageHeader<Guid> mhg = new MessageHeader<Guid>(myToken); MessageHeader untyped = mhg.GetUntypedHeader("token", "ns"); OperationContext.Current.OutgoingMessageHeaders.Add(untyped); proxy.DoOperation(...); } public void DoSomeOTHERStuff() { var proxy = new MyServiceClient(); Guid myToken = Guid.NewGuid(); MessageHeader<Guid> mhg = new MessageHeader<Guid>(myToken); MessageHeader untyped = mhg.GetUntypedHeader("token", "ns"); OperationContext.Current.OutgoingMessageHeaders.Add(untyped); proxy.DoOtherOperation(...); } In other words, is it safe to refactor the above code like this? bool isSetup = false; public void SetupMessageHeader() { if(isSetup) { return; } Guid myToken = Guid.NewGuid(); MessageHeader<Guid> mhg = new MessageHeader<Guid>(myToken); MessageHeader untyped = mhg.GetUntypedHeader("token", "ns"); OperationContext.Current.OutgoingMessageHeaders.Add(untyped); isSetup = true; } public void DoSomeStuff() { var proxy = new MyServiceClient(); SetupMessageHeader(); proxy.DoOperation(...); } public void DoSomeOTHERStuff() { var proxy = new MyServiceClient(); SetupMessageHeader(); proxy.DoOtherOperation(...); } Since I don't really understand what's happening there, I don't want to cargo cult it and just change it and let it fly if it works, I'd like to hear your thoughts on if it is OK or not.

  • gcc returns error with nested class

    - by Nate
    Howdy, I am attempting to use the fully qualified name of my nested class as below, but the compiler is balking! template <class T> class Apple { //constructors, members, whatevers, etc... public: class Banana { public: Banana() { //etc... } //other constructors, members, etc... }; }; template <class K> class Carrot{ public: //etc... void problemFunction() { Apple<int>::Banana freshBanana = someVar.returnsABanana(); //line 85 giveMonkey(freshBanana); //line 86 } }; My issue is, the compiler says: Carrot.h:85: error: expected ';' before 'freshBanana' Carrot.h:86: error: 'freshBanana' was not declared in this scope I had thought that using the fully qualified name permitted me to access this nested class? It's probably going to smack me in the face, but what on earth am I not seeing here??

  • Take most significant 8 bytes of the MD5 hash of a string as a long (in Ruby)

    - by Nate Murray
    Hey Friends, I'm trying to implement a java "hash" function in ruby. Here's the java side: import java.nio.charset.Charset; import java.security.MessageDigest; /** * @return most significant 8 bytes of the MD5 hash of the string, as a long */ protected long hash(String value) { byte[] md5hash; md5hash = md5Digest.digest(value.getBytes(Charset.forName("UTF8"))); long hash = 0L; for (int i = 0; i < 8; i++) { hash = hash << 8 | md5hash[i] & 0x00000000000000FFL; } return hash; } So far, my best guess in ruby is: # WRONG - doesn't work properly. #!/usr/bin/env ruby -wKU require 'digest/md5' require 'pp' md5hash = Digest::MD5.hexdigest("0").unpack("U*") pp md5hash hash = 0 0.upto(7) do |i| hash = hash << 8 | md5hash[i] & 0x00000000000000FF end pp hash Problem is, this ruby code doesn't match the java output. For reference, the above java code given these strings returns the corresponding long: "00038c53790ecedfeb2f83102e9115a522475d73" => -2059313900129568948 "0" => -3473083983811222033 "001211e8befc8ac22dd265ecaa77f8c227d0007f" => 3234260774580957018 Thoughts: I'm having problems getting the UTF8 bytes from the ruby string In ruby I'm using hexdigest, I suspect I should be using just digest instead The java code is taking the md5 of the UTF8 bytes whereas my ruby code is taking the bytes of the md5 (as hex) Any suggestions on how to get the exact same output in ruby?

  • Is this a good way to expose generic base class methods through an interface?

    - by Nate Heinrich
    I am trying to provide an interface to an abstract generic base class. I want to have a method exposed on the interface that consumes the generic type, but whose implementation is ultimately handled by the classes that inherit from my abstract generic base. However I don't want the subclasses to have to downcast to work with the generic type (as they already know what the type should be). Here is a simple version of the only way I can see to get it to work at the moment. public interface IFoo { void Process(Bar_base bar); } public abstract class FooBase<T> : IFoo where T : Bar_base { abstract void Process(T bar); // Explicit IFoo Implementation void IFoo.Process(Bar_base bar) { if (bar == null) throw new ArgumentNullException(); // Downcast here in base class (less for subclasses to worry about) T downcasted_bar = bar as T; if (downcasted_bar == null) { throw new InvalidOperationException( string.Format("Expected type '{0}', not type '{1}'", T.ToString(), bar.GetType().ToString()); } //Process downcasted object. Process(downcasted_bar); } } Then subclasses of FooBase would look like this... public class Foo_impl1 : FooBase<Bar_impl1> { void override Process(Bar_impl1 bar) { //No need to downcast here! } } Obviously this won't provide me compile time Type Checking, but I think it will get the job done... Questions: 1. Will this function as I think it will? 2. Is this the best way to do this? 3. What are the issues with doing it this way? 4. Can you suggest a different approach? Thanks!

  • STM32 Compiler/Debugger Chain?

    - by Nate
    I'm starting a project with a STMicro STM32. I've done the Google searches, looking for solid compiler/debugger chains but would prefer answers with success stories. Open Source Compilers/Linkers would be ideal, I just don't know if their STM32 toolchains are stable yet. (Both C, C++ compilers are acceptable). -- So commercial options are acceptable as well. Do any of you have useful suggestions?

  • Installing GDAL for Python

    - by Nate
    I am trying to install GDAL for python on a Windows XP machine (Python 2.6 currently installed) following the instructions at http://trac.osgeo.org/gdal/wiki/GdalOgrInPython (as is mirrored in a hundred other places). It says I need both the GDAL source (or Windows binary) and the python bindings. The python binding are be downloaded from the python cheeseshop (http://pypi.python.org/pypi/Python_GDAL/1.3.1). I don't see a download link on this page nor can I locate the python binding elsewhere - all instruction I can find seem to point to the same cheeseshop page. This seems like I'm either missing something embarrassingly simple or the bindings file has disappeared. Any thoughts on which it is? Thanks.

  • Invoke an action that is using ASP.NET MVC [Authorize] from outside the application

    - by Nate Bross
    Is this possible? I'd like to expose a URL (action) such as http://mysever/myapp/UpdateHeartbeat/. In my MVC application it looks like [Authorize] [AcceptsVerbs(HttpVerbs.Post)] public ActionResult UpdateHeartbeat() { // update date in DB to DateTime.Now } Now, in my MVC application the user has logged in via FORMS authentication and they can execute that action to their hearts content. What I want to do, is hit that URL progromatically (as part of an API that I wouldl like to build) -- is there a way I can do that without removing the [Authorize] attribute and adding username/password as parameters to the POST?

  • R plot- SGAM plot counts vs. time - how do I get dates on the x-axis?

    - by Nate
    I'd like to plot this vs. time, with the actual dates (years actually, 1997,1998...2010). The dates are in a raw format, ala SAS, days since 1960 (hence as.date conversion). If I convert the dates using as.date to variable x, and do the GAM plot, I get an error. It works fine with the raw day numbers. But I want the plot to display the years (data are not equally spaced). structure(list(site = c(928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L, 928L), date = c(13493L, 13534L, 13566L, 13611L, 13723L, 13752L, 13804L, 13837L, 13927L, 14028L, 14082L, 14122L, 14150L, 14182L, 14199L, 16198L, 16279L, 16607L, 16945L, 17545L, 17650L, 17743L, 17868L, 17941L, 18017L, 18092L), y = c(7L, 7L, 17L, 18L, 17L, 17L, 10L, 3L, 17L, 24L, 11L, 5L, 5L, 3L, 5L, 14L, 2L, 9L, 9L, 4L, 7L, 6L, 1L, 0L, 5L, 0L)), .Names = c("site", "date", "y"), class = "data.frame", row.names = c(NA, -26L)) sgam1 <- gam(sites$y ~ s(sites$date)) sgam <- predict(sgam1, se=TRUE) plot(sites$date,sites$y,xaxt="n", xlab='Time', ylab='Counts') x<-as.Date(sites$date, origin="1960-01-01") axis(1, at=1:26,labels=x) lines(sites$date,sgam$fit, lty = 1) lines(sites$date,sgam$fit + 1.96* sgam$se, lty = 2) lines(sites$date,sgam$fit - 1.96* sgam$se, lty = 2) ggplot2 has a solution (it doesn't mind the as.date thing) but it gives me other problems...

  • Returning large collections from WCF Serivce

    - by Nate Bross
    I'm trying to determine the best approach for building a WCF Service, and the area I'm struggling with most is returning lists of objects. The built-in maxMessageSize of 64k seems pretty high, and I really don't want to bump it up (quick googling finds 100s of places bumping the maxMessageSize up to multi-gigabyte range which seems foolish). But, when I'm returning a collection of objects (~150 items) I am exceeding the default 64k. I'm almost to the point of returning my own class which inherits IEnumerable and has properties for hasNext, hasPrevious and PageSize so that I can implement paging on the client side -- this seems like alot of code. The other option is to jackup the maxMessageSize and hope for the best, but that feels wrong. All other aspects of my service are working great, its just returning large collectiosn where I'm having issues. For background, there are two types of consumers of this service, UI applications which will be primarly web and/or wpf applications, and data processing applications, .NET console apps, and maybe some other non-UI apps. For the UI applications, I would like to keep them responsive and keep the messageSize low, on the console apps it doesn't matter as much as they are just pulling data down to do processing and push it back up to the service.
