  • MVC 3, View Model for user registration process. Password validation not working properly

    - by sec_goat
    I am trying to create a user registration page using MVC 3, so that I can better understand the process of how it works, what's going on behind the scenes etc. I am running into some issues when trying to use [Compare] to check to see that the user entered the same password twice. I tried adding the ComparePassword field to my user model first, and found that would not work the way I wanted as I did not have the field in the database, so the obvious answer was to create a View Model using the same information including the ComparePassword field. So I now have created a User model and a RegistrationViewModel, however it appears that the [Compare] on the password is not returning anything, for instance no matter what I put in the two boxes, when I click create it gives no error, which seems to me to mean it was successfully validated. I am not sure what I am doing or not doing to make this work properly. I have tried updating the jQuery.Validate to the newest version as there were some bugs reported in older version, this has not helped my efforts. Below is a wall of code, that is what I am working with. } public class RegistrationViewModel { [Required] [StringLength(15, MinimumLength = 3)] [Display(Name = "User Name")] [RegularExpression(@"(\S)+", ErrorMessage = " White Space is not allowed in User Names")] [ScaffoldColumn(false)] public String Username { get; set; } [Required] [StringLength(15, MinimumLength = 3)] [Display(Name = "First Name")] public String firstName { get; set; } [Required] [StringLength(15, MinimumLength = 3)] [Display(Name = "Last Name")] public String lastName { get; set; } [Required] [Display(Name = "Email")] public String email { get; set; } [Required] [Display(Name = "Password")] [DataType(DataType.Password)] public String password { get; set; } [Required] [DataType(DataType.Password)] [Display(Name = "Re-enter Password")] [Compare("Password", ErrorMessage = "Passwords do not match.")] public String comparePassword { get; set; } }

  • How do I make a UIAlertView happen only on the first start-up of an iPhone app?

    - by user309245
    I'm using the UIAlertView to make a pop-up happen once the app has started up. It works fine but I only want the pop up to happen on the first start-up of the app. At the moment I've got the UIAlertView in the AppDelegate class, after the application didFinishLaunching. Here is my code at the moment. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { sleep(4); UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Welcome!" message:@"SAMPLE!!!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; [alert show]; [alert release]; I'm new to app development so sorry if this is simple. Thanks in advance! :)

  • Optional parens in Ruby for method with uppercase start letter?

    - by RasmusKL
    I just started out using IronRuby (but the behaviour seems consistent when I tested it in plain Ruby) for a DSL in my .NET application - and as part of this I'm defining methods to be called from the DSL via define_method. However, I've run into an issue regarding optional parens when calling methods starting with an uppercase letter. Given the following program: class DemoClass define_method :test do puts "output from test" end define_method :Test do puts "output from Test" end def run puts "Calling 'test'" test() puts "Calling 'test'" test puts "Calling 'Test()'" Test() puts "Calling 'Test'" Test end end demo = DemoClass.new demo.run Running this code in a console (using plain ruby) yields the following output: ruby .\test.rb Calling 'test' output from test Calling 'test' output from test Calling 'Test()' output from Test Calling 'Test' ./test.rb:13:in `run': uninitialized constant DemoClass::Test (NameError) from ./test.rb:19:in `<main>' I realize that the Ruby convention is that constants start with an uppercase letter and that the general naming convention for methods in Ruby is lowercase. But the parens are really killing my DSL syntax at the moment. Is there any way around this issue?

  • Where is mpx386.6 and start.c in Minix 3.2?

    - by John Bowlinger
    I'm trying to follow along in Operating Systems and Implementation 3rd edition and I'm now at the part in the book where Tanenbaum is discussing bootup and kernel process switching. He keeps referring to these 2 files (mpx386.s, start.c) that are supposedly in a directory called kernel, but I can't seem to find them. In the root directory, when I go to boot/minix/3.2.0/kernel, kernel just seems to be a binary file that is illegible in terminal. There also seems to be a bunch of mod01-mod12 gz binary files as well in the 3.2.0 directory. Am I in the wrong directory, or is there something I need to install and do to read kernel? I would like to follow along with the book to what's on my screen, instead of constantly flipping back and forth. I realize alot of files are completely different from this book published in 2006 and I accept that, but this seems to be a critical juncture of the book and the operating system as a whole. If it's any consolation, I'm running the OS in Virtualbox on a 64-bit Macbook.

  • using threads in menu options

    - by vbNewbie
    I have an app that has a console menu with 2/3 selections. One process involves uploading a file and performing a lengthy search process on its contents, whilst another process involves SQL queries and is an interactive process with the user. I wish to use threads to allow one process to run and the menu to offer the option for the second process to run. However you cannot run the first process twice. I have created threads and corrected some compilation errors but the threading options are not working correctly. Any help appreciated. main... Dim tm As Thread = New Thread(AddressOf loadFile) Dim ts As Thread = New Thread(AddressOf reports) .... While Not response.Equals("3") Try Console.Write("Enter choice: ") response = Console.ReadLine() Console.WriteLine() If response.Equals("1") Then Console.WriteLine("Thread 1 doing work") tm.SetApartmentState(ApartmentState.STA) tm.IsBackground = True tm.Start() response = String.Empty ElseIf response.Equals("2") Then Console.WriteLine("Starting a second Thread") ts.Start() response = String.Empty End If ts.Join() tm.Join() Catch ex As Exception errormessage = ex.Message End Try End While I realize that a form based will be easier to implement with perhaps just calling different forms to handle the processes.But I really dont have that option now since the console app will be added to api later. But here are my two processes from the menu functions. Also not sure what to do with the boolean variabel again as suggested below. Private Sub LoadFile() Dim dialog As New OpenFileDialog Dim response1 As String = Nothing Dim filepath As String = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) dialog.InitialDirectory = filepath If dialog.ShowDialog() = DialogResult.OK Then fileName = dialog.FileName ElseIf DialogResult.Cancel Then Exit Sub End If Console.ResetColor() Console.Write("Begin Search -- Discovery Search, y or n? ") response1 = Console.ReadLine() If response1 = "y" Then Search() ElseIf response1 = "n" Then Console.Clear() main() End If isRunning = False End Sub and the second one Private Shared Sub report() Dim rptGen As New SearchBlogDiscovery.rptGeneration Console.WriteLine("Tread Process started") rptGen.main() Console.WriteLine("Thread Process ended") isRunning = False End Sub

  • Is it possible to start an activity from a regular java class?

    - by Yotam
    In my ActionBarSherlock I have the same menu items for all activities, so it seems unwise to define onClick handlers in each activity - they all do the same. Instead I created a class called MyClickListener that implements com.actionbarsherlock.view.MenuItem.OnMenuItemClickListener, and in there I have a simple switch block that starts the appropriate activity. Problem is that Intent constructor's first argument is of type Context, and even when I pass this to MyClickListener's constructor, I can't start any activity. The same goes for every method that has a Context object as a parameter. Is there a way to work around it? What is a context object? Thanks

  • How can I create a menu in the start menu for my program?

    - by Joe
    This may be an easy question but I am not even sure of the terminology to search, so I have to ask. I want my program to have a menu when it is hovered over if it is pinned to the start menu. I am attaching a screenshot where windows powershell illustrates this function, and presents a list of tasks. Other programs sometimes use this to list recently opened files, etc. I am sure this is standard enough that there is a tutorial on it somewhere, would someone mind pointing me to it, or explaining how to do this? I hope that it doesn't matter too much what language is used, but I am proficient in Delphi, C++, and C#.

  • from JS to iphone dev - what's the best language to start with?

    - by Enkai
    I am a total beginner and would like to eventually learn to develop for the iphone. I have just done a beginner's CS course where the language we learned was JavaScript. We studied basic concepts like: variables, arrays, loops (for,while,if,if..else..), properties and functions. I'm wondering if I am starting in the right/wrong place by following this book: Learn C on the Mac by Dave Mark? I have read a few chapters and am finding it a bit hard to get my head around the way that C works, for example the way that Strings are printed seems overly complicated as compared to JS. Do you think that JS was the wrong language to start off with and would I be better to go from JS straight to Objective-C rather than to C? I have tried to read up on previous threads on the merits/demerits of learning C first but haven't found any that relate JS to learning C/Obj C/ Cocoa. Any advice appreciated as I am very new to this. Thanks

  • Where is the best place to start learning Java Socket Programming?

    - by MarcoBoomTing
    I wish to create a Java Socket server which can be connected to using Javascript and/or Flash. I have experience in Connecting to sockets in flash, and using a comet like system in Ajax. I wish to make a live communication system, which will intale multiple connections to the server from various clients, needing almost instant communication between peers. I coded a system like this in PHP but I want to convert it to Java, simply because I don't want the PHP engine to be tied up on this Sever, as it serves all the web stuff normally on the site, and i've heard is more powerful for this sort of thing. Just looking for advice on where I can start learning how to write this sort of system using Java? I have previous coding experience in PHP, Javascript, Adobe Air and AS3 if That helps?

  • GTK+: How do I process RadioMenuItem choice without marking it chosen? And vise versa

    - by eugene.shatsky
    In my program, I've got a menu with a group of RadioMenuItem entries. Choosing one of them should trigger a function which can either succeed or fail. If it fails, this RadioMenuItem shouldn't be marked chosen (the previous one should persist). Besides, sometimes I want to set marked item without running the choice processing function. Here is my current code: # Update seat menu list def update_seat_menu(self, seats, selected_seat=None): seat_menu = self.builder.get_object('seat_menu') # Delete seat menu items for menu_item in seat_menu: # TODO: is it a good way? does remove() delete obsolete menu_item from memory? if menu_item.__class__.__name__ == 'RadioMenuItem': seat_menu.remove(menu_item) # Fill menu with new items group = [] for seat in seats: menu_item = Gtk.RadioMenuItem.new_with_label(group, str(seat[0])) group = menu_item.get_group() seat_menu.append(menu_item) if str(seat[0]) == selected_seat: menu_item.activate() menu_item.connect("activate", self.choose_seat, str(seat[0])) menu_item.show() # Process item choice def choose_seat(self, entry, seat_name): # Looks like this is called when item is deselected, too; must check if active if entry.get_active(): # This can either succeed or fail self.logind.AttachDevice(seat_name, '/sys'+self.device_syspath, True) Chosen RadioMenuItem gets marked irrespective of the choose_seat() execution result; and the only way to set marked item without triggering choose_seat() is to re-run update_seat_menu() with selected_seat argument, which is an overkill. I tried to connect choose_seat() with 'button-release-event' instead of 'activate' and call entry.activate() in choose_seat() if AttachDevice() succeeds, but this resulted in whole X desktop lockup until AttachDevice() timed out, and chosen item still got marked.

  • How do I specify a dynamic position for the start of substring?

    - by analyticsPierce
    As in the example, I am trying to substring the Video_full column in a data.frame (video_data_2) I am working on. I want to keep all the characters after the period. The period is always present, there is only one period and it is in a different position in each value for the column. Date Video_full Instances 1 Apr 1, 2010 installs/AA.intro_video_1 546 2 Apr 1, 2010 installs/ABAC.intro_video_2 548 I got substring to work; video_data_2$Video_full <- substring(video_data_2$Video_full,11) And strsplit also; strsplit("installs/AA.intro_video_1 ",'[.]') I'm just not able to figure out how to start the substring in a dynamic position or only keep the second value returned by strsplit. Thanks for any help you can offer for a simple question.

  • Beginning Programmer Interested in Android - Should I Start with Java?

    - by Hudey
    I'm a beginner in programming. My experience so far is only in Actionscript 2 and 3. So I have a basic understanding of declaring variables, loops, arrays, if/then, do/while... I'm wanting to move to developing for Android phones so I'm wondering what suggestions people have for where to go next. Should I jump right to Android? Start with a 'beginning Java' approach? Or should I go some other route to beef up my knowledge of OOP concepts before launching into Android? I have my Dev environment set up and completed the Hello Android tutorial and I'm just wondering if I am going to be in over my head quickly?

  • How can I start XServer in Linux through apache user triggered by Perl script running in background?

    - by Nikhil
    I am trying to launch MS Office through WINE using a PERL script hosted by apache and and triggered by other application. I am getting the following error message in log files "Application trying to create a window but no driver could not be loaded. Make sure that your X server is running and that $DISPLAY is set correctly". If I run the script directly on shell prompt using root user then WINE starts XServer properly and execute MS MSoffice in addition to that if I set xhost +local:apache on shell prompt then also it works fine. How can I start the XServer from apache user?

  • When to give in and start The Big Rewrite?

    - by John Cromartie
    I've had my share of projects where the first thing I think is "let's just rewrite it in ." Everybody feels the urge at some point. In fact, I think I've had the urge to rewrite pretty much every project I've ever been on. However, it is accepted wisdom that a total rewrite is generally a bad idea. The question is: when do you look at a project and say: "OK, it's time to start over." What sort of metrics or examples can you cite of where a rewrite was truly necessary? How bad does the code have to be? How old can a project get before there too much invested?

  • How does this code block works?

    - by Justin John
    I can't understand how the following code works. $start = 1; while($start<10){ if ($start&1) { echo "ODD ".$start." <br/> "; } else { echo "EVEN ".$start." <br/> "; } $start++; } The $start&1 will return ODD and EVEN seperately. Output ODD 1 EVEN 2 ODD 3 EVEN 4 ODD 5 EVEN 6 ODD 7 EVEN 8 ODD 9 If we give $start&2 instead of $start&1, it returns with another order. How &1 &2 etc... works here?

    - by Joe K
    I'm very new to programming, but it has always interested me. I've tried to learn a couple of times except I don't know where to begin. What's a good language to learn first? What is a good website that can help me learn it? I once partitioned my hard drive and installed Ubuntu in an attempt to learn Python, but I was overwhelmed. I didn't know where to start or what to do. All suggestions, feedback, comments are welcome.

  • Wrong encoding in DataReceivedEventArgs

    - by user2102508
    I start cmd.exe process and redirect stdin to pass script to it and redirect stdout and stderr to read cmd's output. Here is the code of my DataReceivedEventHandler: (o, a) => { if(!String.IsNullOrEmpty(a.Data)) { bw.Write(a.Data.ToUTF8()); bw.Write((byte)'\n'); } } In the code bw is instance of BinaryWriter, ToUTF8 is string extension method, that converts a string to UTF8 encoded byte array. When I use this code in a separate process it works well, however when I use this code as a shared library inside some other process a.Data doesn't contain valid localized characters (like russian characters for example). So how should I convert characters? How to get cmd's OEM encoding? Why does the code works well in a separate process and doesn't work as a shared library inside some other process?

    Faut-il être développeur pour lancer une start-up viable ? Oui, selon un expert des projets d'entreprise IT, mais a-t-il raison ? Le succès des startups informatiques, notamment dans le domaine des réseaux sociaux (à l'instar des success story Facebook et Twitter) fait rêver les entrepreneurs. Peut-être même un peu trop. On le constate sur les sites d'emploi, les mailing-list ou les forums de discussion où souvent, des entrepreneurs non-développeurs postent des annonces à la recherche "d'excellents développeurs" capable implémenter leur idée de génie.

  • Creating an SMF service for mercurial web server

    - by Chris W Beal
    I'm working on a project at the moment, which has a number of contributers. We're managing the project gate (which is stand alone) with mercurial. We want to have an easy way of seeing the changelog, so we can show management what is going on.  Luckily mercurial provides a basic web server which allows you to see the changes, and drill in to change sets. This can be run as a daemon, but as it was running on our build server, every time it was rebooted, someone needed to remember to start the process again. This is of course a classic usage of SMF. Now I'm not an experienced person at writing SMF services, so it took me 1/2 an hour or so to figure it out the first time. But going forward I should know what I'm doing a bit better. I did reference this doc extensively. Taking a step back, the command to start the mercurial web server is $ hg serve -p <port number> -d So we somehow need to get SMF to run that command for us. In the simplest form, SMF services are really made up of two components. The manifest Usually lives in /var/svc/manifest somewhere Can be imported from any location The method Usually live in /lib/svc/method I simply put the script straight in that directory. Not very repeatable, but it worked Can take an argument of start, stop, or refresh Lets start with the manifest. This looks pretty complex, but all it's doing is describing the service name, the dependencies, the start and stop methods, and some properties. The properties can be by instance, that is to say I could have multiple hg serve processes handling different mercurial projects, on different ports simultaneously Here is the manifest I wrote. I stole extensively from the examples in the Documentation. So my manifest looks like this $ cat hg-serve.xml <?xml version="1.0"?> <!DOCTYPE service_bundle SYSTEM "/usr/share/lib/xml/dtd/service_bundle.dtd.1"> <service_bundle type='manifest' name='hg-serve'> <service name='application/network/hg-serve' type='service' version='1'> <dependency name='network' grouping='require_all' restart_on='none' type='service'> <service_fmri value='svc:/milestone/network:default' /> </dependency> <exec_method type='method' name='start' exec='/lib/svc/method/hg-serve %m' timeout_seconds='2' /> <exec_method type='method' name='stop' exec=':kill' timeout_seconds='2'> </exec_method> <instance name='project-gate' enabled='true'> <method_context> <method_credential user='root' group='root' /> </method_context> <property_group name='hg-serve' type='application'> <propval name='path' type='astring' value='/src/project-gate'/> <propval name='port' type='astring' value='9998' /> </property_group> </instance> <stability value='Evolving' /> <template> <common_name> <loctext xml:lang='C'>hg-serve</loctext> </common_name> <documentation> <manpage title='hg' section='1' /> </documentation> </template> </service> </service_bundle> So the only things I had to decide on in this are the service name "application/network/hg-serve" the start and stop methods (more of which later) and the properties. This is the information I need to pass to the start method script. In my case the port I want to start the web server on "9998", and the path to the source gate "/src/project-gate". These can be read in to the start method. So now lets look at the method scripts $ cat /lib/svc/method/hg-serve #!/sbin/sh # # # Copyright (c) 2012, Oracle and/or its affiliates. All rights reserved. # # Standard prolog # . /lib/svc/share/smf_include.sh if [ -z $SMF_FMRI ]; then echo "SMF framework variables are not initialized." exit $SMF_EXIT_ERR fi # # Build the command line flags # # Get the port and directory from the SMF properties port=`svcprop -c -p hg-serve/port $SMF_FMRI` dir=`svcprop -c -p hg-serve/path $SMF_FMRI` echo "$1" case "$1" in 'start') cd $dir /usr/bin/hg serve -d -p $port ;; *) echo "Usage: $0 {start|refresh|stop}" exit 1 ;; esac exit $SMF_EXIT_OK This is all pretty self explanatory, we read the port and directory using svcprop, and use those simply to run a command in the start case. We don't need to implement a stop case, as the manifest says to use "exec=':kill'for the stop method. Now all we need to do is import the manifest and start the service, but first verify the manifest # svccfg verify /path/to/hg-serve.xml If that doesn't give an error try importing it # svccfg import /path/to/hg-serve.xml If like me you originally put the hg-serve.xml file in /var/svc/manifest somewhere you'll get an error and told to restart the import service svccfg: Restarting svc:/system/manifest-import The manifest being imported is from a standard location and should be imported with the command : svcadm restart svc:/system/manifest-import # svcadm restart svc:/system/manifest-import and you're nearly done. You can look at the service using svcs -l # svcs -l hg-serve fmri svc:/application/network/hg-serve:project-gate name hg-serve enabled false state disabled next_state none state_time Thu May 31 16:11:47 2012 logfile /var/svc/log/application-network-hg-serve:project-gate.log restarter svc:/system/svc/restarter:default contract_id 15749 manifest /var/svc/manifest/network/hg/hg-serve.xml dependency require_all/none svc:/milestone/network:default (online) And look at the interesting properties # svcprop hg-serve hg-serve/path astring /src/project-gate hg-serve/port astring 9998 ...stuff deleted.... Then simply enable the service and if every things gone right, you can point your browser at http://server:9998 and get a nice graphical log of project activity. # svcadm enable hg-serve # svcs -l hg-serve fmri svc:/application/network/hg-serve:project-gate name hg-serve enabled true state online next_state none state_time Thu May 31 16:18:11 2012 logfile /var/svc/log/application-network-hg-serve:project-gate.log restarter svc:/system/svc/restarter:default contract_id 15858 manifest /var/svc/manifest/network/hg/hg-serve.xml dependency require_all/none svc:/milestone/network:default (online) None of this is rocket science, but a bit fiddly. Hence I thought I'd blog it. It might just be you see this in google and it clicks with you more than one of the many other blogs or how tos about it. Plus I can always refer back to it myself in 3 weeks, when I want to add another project to the server, and I've forgotten how to do it.

  • Can I get a bitmap of an arbitrary window in another application process?

    - by Chris Farmer
    I am trying to automate a third-party Win32 application where I want to capture the graphics content of a particular window at defined time intervals. I am in the early phases of this, and I'm currently trying to use the Microsoft UI Automation API via C# to do most of the interaction between my client app and the external app. I can now get the external app to do what I want it to do, but now I want to capture the graphics from a specific window that seems to be some third-party owner-drawn control. How can I do this? The window I want to capture is the one marked by the red rectangle in this image: I have an implementation that sort of works, but it's dependent on the external app's UI being on top, and that's not guaranteed for me, so I'd prefer to find something more general. var p = Process.Start("c:\myapp.exe"); var mainForm = AutomationElement.FromHandle(p.MainWindowHandle); // "workspace" below is the window whose content I want to capture. var workspace = mainForm.FindFirst(TreeScope.Descendents, new PropertyCondition(AutomationElement.ClassNameProperty, "AfxFrameOrView70u")); var rect = (Rect) workspace.GetCurrentPropertyValue(AutomationElement.BoundingRectangleProperty); using (var bmp = new Bitmap((int)rect.Width, (int)rect.Height)) { using (var g = Graphics.FromImage(bmp)) { g.CopyFromScreen((int)rect.Left, (int)rect.Top, 0, 0, new Size((int)rect.Width, (int)rect.Height)); bmp.Save(@"c:\screenshot.png", ImageFormat.Png); } } The above works well enough when the automated app is on top, but it just blindly copies the screen in the rectangle, so my code is at the mercy of whatever happens to be running on the machine and might cover my app's window. I have read some suggestions to send the WM_PRINT message to the window. This question/answer from a few months back seemed promising, but when I use this code, I just get a white rectangle with none of my control's actual contents. var prop = (int)workspace.GetCurrentPropertyValue(AutomationElement.NativeWindowHandleProperty); var hwnd = new IntPtr(prop); using ( var bmp2 = new Bitmap((int)rect.Width, (int)rect.Height)) { using (Graphics g = Graphics.FromImage(bmp2)) { g.FillRectangle(SystemBrushes.Control, 0, 0, (int)rect.Width, (int)rect.Height); try { SendMessage(hwnd, WM_PRINT, g.GetHdc().ToInt32(), (int)(DrawingOptions.PRF_CHILDREN | DrawingOptions.PRF_CLIENT | DrawingOptions.PRF_OWNED)); } finally { g.ReleaseHdc(); } bmp2.Save(@"c:\screenshot.bmp"); } } So, first, is it even possible for me to reliably save a bitmap of a window's contents? If so, what is the best way, and what is wrong with my WM_PRINT with SendMessage attempt?

  • How to launch a Windows service network process to listen to a port on a localhost socket that is vi

    - by rwired
    Here's the code (in a standard TService in Delphi): const ProcessExe = 'MyNetApp.exe'; function RunService: Boolean; var StartInfo : TStartupInfo; ProcInfo : TProcessInformation; CreateOK : Boolean; begin CreateOK := false; FillChar(StartInfo,SizeOf(TStartupInfo),#0); FillChar(ProcInfo,SizeOf(TProcessInformation),#0); StartInfo.cb := SizeOf(TStartupInfo); CreateOK := CreateProcess(nil, PChar(ProcessEXE),nil,nil,False, CREATE_NEW_PROCESS_GROUP+NORMAL_PRIORITY_CLASS, nil, PChar(InstallDir), StartInfo, ProcInfo); CloseHandle(ProcInfo.hProcess); CloseHandle(ProcInfo.hThread); Result := CreateOK; end; procedure TServicel.ServiceExecute(Sender: TService); const IntervalsBetweenRuns = 4; //no of IntTimes between checks IntTime = 250; //ms var Count: SmallInt; begin Count := IntervalsBetweenRuns; //first time run immediately while not Terminated do begin Inc(Count); if Count >= IntervalsBetweenRuns then begin Count := 0; //We check to see if the process is running, //if not we run it. That's all there is to it. //if ProcessEXE crashes, this service host will just rerun it if processExists(ProcessEXE)=0 then RunService; end; Sleep(IntTime); ServiceThread.ProcessRequests(False); end; end; MyNetApp.exe is a SOCKS5 proxy listening on port 9870. Users configure their browser to this proxy which acts as a secure-tunnel/anonymizer. All works perfectly fine on 2000/XP/2003, but on Vista/Win7 with UAC the service runs in Session0 under LocalSystem and port 9870 doesn't show up in netstat for the logged-in user or Administrator. Seems UAC is getting in my way. Is there something I can do with the SECURITY_ATTRIBUTES or CreateProcess, or is there something I can do with CreateProcessAsUser or impersonation to ensure that a network socket on a service is available to logged-in users on the system (note, this app is for mass deployment, I don't have access to user credentials, and require the user elevate their privileges to install a service on Vista/Win7)
