  • UIActivityIndicatorView is not display at the right time

    - by Alexandre
    I'm making a form that allows the user to enter datas in my IOS application. This form allows the user to enter a lot of repetive datas. So, sometimes, the process takes time and I would like to display a UIActivityIndicatorView during this process. Unfortunalty the spinner appears only one second or less at the end of the process, not at the beginning as expected. There is some code : - (void) manageSpinner{ spinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; [spinner setCenter:CGPointMake(self.view.bounds.size.width/2.0, self.view.bounds.size.height/2.0)]; // I do this becau I'm in landscape mode UIImageView *imageView = [[UIImageView alloc]initWithFrame:self.tableView.bounds]; UIImage *image = [UIImage imageNamed:@"dark_gradiant.jpg"]; [imageView setImage:image]; [imageView addSubview:spinner]; [self.tableView addSubview:imageView]; [spinner startAnimating]; } //On click save by the user - (IBAction)save:(id)sender{ //Collect information from the form myObject.name = nameTF.text; [...] if(informations OK[...]){ //Manage spinner [self manageSpinner]; //Add : this is the long process for (int i=0; i<nbRepeatChooseByUser; i++) { [myObject register]; } //Call the delegate that will dismiss the form [self.delegate theSaveButtonOnTheAddMyObjectTVCWasTapped:self]; } } The spinner is called before the adding method but it seems to be set up after the process. Thank you, Alexandre

  • Configure TFS portal afterwards

    Update #1 January 8th, 2010: There is an updated post on this topic for Beta 2: http://www.ewaldhofman.nl/post/2009/12/10/Configure-TFS-portal-afterwards-Beta-2.aspx Update #2 October 10th, 2010: In the new Team Foundation Server Power Tools September 2010, there is now a command to create a portal. tfpt addprojectportal   Add or move portal for an existing team project Usage: tfpt addprojectportal /collection:uri                              /teamproject:"project name"                              /processtemplate:"template name"                              [/webapplication:"webappname"]                              [/relativepath:"pathfromwebapp"]                              [/validate]                              [/verbose] /collection Required. URL of Team Project Collection. /teamproject Required. Specifies the name of the team project. /processtemplate Required. Specifies that name of the process template. /webapplication The name of the SharePoint Web Application. Must also specify relativepath. /relativepath The path for the site relative to the root URL for the SharePoint Web Application. Must also specify webapplication. /validate Specifies that the user inputs are to be validated. If specified, only validation will be done and no portal setting will be changed. /verbose Switches on the verbose mode. I created a new Team Project in TFS 2010 Beta 1 and choose not to configure SharePoint during the creation of the Team Project. Of course I found out fairly quickly that a portal for TFS is very useful, especially the Iteration and the Product backlog workbooks and the dashboard reports. This blog describes how you can configure the sharepoint portal afterwards. Update: September 9th, 2009 Adding the portal afterwards is much easier as described below. Here are the steps Step 1: Create a new temporary project (with a SharePoint site for it). Open the Team Explorer Right click in the Team Explorer the root node (i.e. the project collection) Select "New team project" from the menu Walk throught he wizard and make sure you check the option to create the portal (which is by default checked) Step 2: Disable the site for the new project Open the Team Explorer Select the team project you created in step 1 In the menu click on Team -> Show Project Portal. In the menu click on Team -> Team Project Settings -> Portal Settings... The following dialog pops up Uncheck the option "Enable team project portal" Confirm the dialog with OK Step 3: Enable the site for the original one. Point it to the newly created site. Open the Team Explorer Select the team project you want to add the portal to In the menu open Team -> Team Project Settings -> Portal Settings... The same dialog as in step 2 pops up Check the option "Enable team project portal" Click on the "Configure URL" button The following dialog pops up   In the dialog select in the combobox of the web application the TFS server Enter in the Relative site path the text "sites/[Project Collection Name]/[Team Project Name created in step 1]" Confirm the "Specify an existing SharePoint Site" with OK Check the "Reports and dashboards refer to data for this team project" option Confirm the dialog "Project Portal Settings" with OK Step 4: Delete the temporary project you created. In Beta 1, I have found no way to delete a team project. Maybe it will be available in TFS 2010 Beta 2. Original post Step 1: Create new portal site Go to the sharepoint site of your project collection (/sites//default.aspx">/sites//default.aspx">http://<servername>/sites/<project_collection_name>/default.aspx) Click on the Site Actions at the left side of the screen and choose the option Site Settings In the site settings, choose the Sites and workspaces option Create a new site Enter the values for the Title, the description, the site address. And choose for the TFS2010 Agile Dashboard as template. Create the site, by clicking on the Create button Step 2: Integrate portal site with team project Open Visual Studio Open the Team Explorer (View -> Team Explorer) Select in the Team Explorer tool window the Team Project for which you are create a new portal Open the Project Portal Settings (Team -> Team Project Settings -> Portal Setings...) Check the Enable team project portal checkbox Click on Configure URL... You will get a new dialog as below Enter the url to the TFS server in the web application combobox And specify the relative site path: sites/<project collection>/<site name> Confirm with OK Check in the Project Portal Settings dialog the checkbox "Reports and dashboards refer to data for this team project" Confirm the settings with OK (this takes a while...) When you now browse to the portal, you will see that the dashboards are now showing up with the data for the current team project. Step 3: Download process template To get a copy of the documents that are default in a team project, we need to have a fresh set of files that are not attached to a team project yet. You can do that with the following steps. Start the Process Template Manager (Team -> Team Project Collection Settings -> Process Template Manager...) Choose the Agile process template and click on download Choose a folder to download Step 4: Add Product and Iteration backlog Go to the Team Explorer in Visual Studio Make sure the team project is in the list of team projects, and expand the team project Right click the Documents node, and choose New Document Library Enter "Shared Documents", and click on Add Right click the Shared Documents node and choose Upload Document Go the the file location where you stored the process template from step 3 and then navigate to the subdirectory "Agile Process Template 5.0\MSF for Agile Software Development v5.0\Windows SharePoint Services\Shared Documents\Project Management" Select in the Open Dialog the files "Iteration Backlog" and "Product Backlog", and click Open Step 5: Bind Iteration backlog workbook to the team project Right click on the "Iteration Backlog" file and select Edit, and confirm any warning messages Place your cursor in cell A1 of the Iteration backlog worksheet Switch to the Team ribbon and click New List. Select your Team Project and click Connect From the New List dialog, select the Iteration Backlog query in the Workbook Queries folder. The final step is to add a set of document properties that allow the workbook to communicate with the TFS reporting warehouse. Before we create the properties we need to collect some information about your project. The first piece of information comes from the table created in the previous step.  As you collect these properties, copy them into notepad so they can be used in later steps. Property How to retrieve the value? [Table name] Switch to the Design ribbon and select the Table Name value in the Properties portion of the ribbon [Project GUID] In the Visual Studio Team Explorer, right click your Team Project and select Properties.  Select the URL value and copy the GUID (long value with lots of characters) at the end of the URL [Team Project name] In the Properties dialog, select the Name field and copy the value [TFS server name] In the Properties dialog, select the Server Name field and copy the value [UPDATE] I have found that this is not correct: you need to specify the instance of your SQL Server. The value is used to create a connection to the TFS cube. Switch back to the Iteration Backlog workbook. Click the Office button and select Prepare – Properties. Click the Document Properties – Server drop down and select Advanced Properties. Switch to the Custom tab and add the following properties using the values you collected above. Variable name Value [Table name]_ASServerName [TFS server name] [Table name]_ASDatabase tfs_warehouse [Table name]_TeamProjectName [Team Project name] [Table name]_TeamProjectId [Project GUID] Click OK to close the properties dialog. It is possible that the Estimated Work (Hours) is showing the #REF! value. To resolve that change the formula with: =SUMIFS([Table name][Original Estimate]; [Table name][Iteration Path];CurrentIteration&"*";[Table name][Area Path];AreaPath&"*";[Table name][Work Item Type]; "Task") For example =SUMIFS(VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Original Estimate]; VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Iteration Path];CurrentIteration&"*";VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Area Path];AreaPath&"*";VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Work Item Type]; "Task") Also the Total Remaining Work in the Individual Capacity table may contain #REF! values. To resolve that change the formula with: =SUMIFS([Table name][Remaining Work]; [Table name][Iteration Path];CurrentIteration&"*";[Table name][Area Path];AreaPath&"*";[Table name][Assigned To];[Team Member];[Table name][Work Item Type]; "Task") For example =SUMIFS(VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Remaining Work]; VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Iteration Path];CurrentIteration&"*";VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Area Path];AreaPath&"*";VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Assigned To];[Team Member];VSTS_ab392b55_6647_439a_bae4_8c66e908bc0d[Work Item Type]; "Task") Save and close the workbook. Step 6: Bind Product backlog workbook to the team project Repeat the steps for binding the Iteration backlog for thiw workbook too. In the worksheet Capacity, the formula of the Storypoints might be missing. You can resolve it with: =IF([Iteration]="";"";SUMIFS([Table name][Story Points];[Table name][Iteration Path];[Iteration]&"*")) Example =IF([Iteration]="";"";SUMIFS(VSTS_487f1e4c_db30_4302_b5e8_bd80195bc2ec[Story Points];VSTS_487f1e4c_db30_4302_b5e8_bd80195bc2ec[Iteration Path];[Iteration]&"*"))

  • How to find working directory which works between different computers. - C

    - by Jamie Keeling
    Hello, I am running two processes,Process A is opened by Process B using the following example: createProcessHandle = CreateProcess( TEXT("C:\\Users\Jamie\\Documents\\Application\\Debug\\ProcessA.exe"), TEXT(""), NULL, NULL, FALSE, 0, NULL, NULL, &startupinfo, &process_information ); As you can see the Process is reliant on the path given to it, the problem I have is that if I change the location of my ProcessA.exe (Such as a backup/duplicate) it's a tiresome process to keep recoding the path. I want to be able to make it run no matter where it is without having to recode the path manually. Can anybody suggest a solution to this?

  • MonoTouch App Crashes When Returning From MFMailComposeViewController

    - by Richard Khan
    My MonoTouch Version Info: Release ID: 20401003 Git revision: 2f1746af36f421d262dcd2b0542ce86b12158f02 Build date: 2010-12-23 23:13:38+0000 The MFMailComposeViewController is displayed and works correctly as a dialog using the following code: if (MFMailComposeViewController.CanSendMail) { MFMailComposeViewController mail; mail = new MFMailComposeViewController (); mail.SetSubject ("Subject Test"); mail.SetMessageBody ("Body Test", false); mail.Finished += HandleMailFinished; this.navigationController.PresentModalViewController (mail, true); } else { new UIAlertView ("Mail Failed", "Mail Failed", null, "OK", null).Show (); } However, once the user selects Cancel | Delete Draft or Cancel | Save Draft or Send, the App throws a run-time error like the following: Stacktrace: at (wrapper managed-to-native) MonoTouch.UIKit.UIApplication.UIApplicationMain (int,string[],intptr,intptr) <0x00004 at (wrapper managed-to-native) MonoTouch.UIKit.UIApplication.UIApplicationMain (int,string[],intptr,intptr) <0x00004 at MonoTouch.UIKit.UIApplication.Main (string[],string,string) [0x00038] in /Users/plasma/Source/iphone/monotouch/UIKit/UIApplication.cs:26 at MonoTouch.UIKit.UIApplication.Main (string[]) [0x00000] in /Users/plasma/Source/iphone/monotouch/UIKit/UIApplication.cs:31 at MailDialog.Application.Main (string[]) [0x00000] in /Users/rrkhan/Projects/Sandbox/MailDialog/Main.cs:15 at (wrapper runtime-invoke) .runtime_invoke_void_object (object,intptr,intptr,intptr) Native stacktrace: 0 MailDialog 0x000be66f mono_handle_native_sigsegv + 343 1 MailDialog 0x0000e43e mono_sigsegv_signal_handler + 313 2 libSystem.B.dylib 0x903e946b _sigtramp + 43 3 ???

  • How to get around batch file processing limit

    I have a Windows batch file that processes all the files in a given directory. I have 206,783 files I need to process: for %%f in (*.xml) do call :PROCESS %%f goto :STOP :PROCESS :: do something with the file program.exe %1 > %1.new set /a COUNTER=%COUNTER%+1 goto :EOF :STOP @echo %COUNTER% files processed When I run the batch file, the following output is written: 65535 files processed As part of the processing, an output file is created for each file procesed, with a .new extension. When I do a dir *.new it reports 65,535 files exist. So, it appears my command environment has a hard limit on the number of files it can recognize, and that limit is 64K - 1. Is there a way to extend the command environment to manage more than 64K - 1 files? If not, would a VBScript or JavaScript be able to process all 206,783 files? I'm running on Windows 2003 server, Enterprise Edition, 32-bit. UPDATE It looks like the root cause of my issue was with the built-in Windows "extract" command for ZIP files. The files I have to process were copied from another system via a ZIP file. My server doesn't have a ZIP utility installed, just the native Windows commands. I right-clicked on the ZIP file, and did an "Extract all...", which apparently just extracted the first 65,535 files. I downloaded and installed 7-zip onto my server, unzipped all the files, and my batch script worked as intended.

  • java Processbuilder - exec a file which is not in path on OS X

    - by Jakob
    Okay i'm trying to make ChucK available in exported Processing sketches, i.e. if i export an app from Processing, the ChucK VM binary will be executed from inside the app. So as a user of said app you don't need to worry about ChucK being in your path at all. Right now i'm generating and executing a bash script file, but this way i don't get any console output from ChucK back into Processing: #!/bin/bash cd "[to where the Chuck executable is located]" ./chuck --kill killall chuck # just to make sure ./chuck chuckScript1.ck cuckScriptn.ck then Process p = Runtime.getRuntime().exec("chmod 777 "+scriptPath); p = Runtime.getRuntime().exec(scriptPath); This works but i want to run ChucK directly from Processing instead, but can't get it to execute: String chuckPath = "[folder in which the chuck executable is located]" ProcessBuilder builder = new ProcessBuilder (chuckPath+"/chuck", "test.ck"); final Process process = builder.start(); InputStream is = process.getInputStream(); InputStreamReader isr = new InputStreamReader(is); BufferedReader br = new BufferedReader(isr); String line; while((line = br.readLine()) != null) println(line); println("done chuckin'! exitValue: " + process.exitValue()); Sorry if this is newbie style :D

  • Visual Studio Plug-in that can tell the Application Pool name of w3wp.exe when debugging

    Is there any plug-in for Visual Studio that can display the associated Application Pool name for those w3wp processes when debugging them with "Attach to Process..." ? Usually I have to do following steps before debugging: c: \Windows\system32\inetsrv\appcmd list wps then I get the process id for the Application Pool I want to debug, and then attach it in the Attach to Process window. I feel it will be very pleasure if there's a plug in can do this automatically, but didn't find any such thing after Googled.

  • Run bat file in Java and wait 2

    - by Savvas Dalkitsis
    This is a followup question to my other question : http://stackoverflow.com/questions/2434125/run-bat-file-in-java-and-wait The reason i am posting this as a separate question is that the one i already asked was answered correctly. From some research i did my problem is unique to my case so i decided to create a new question. Please go read that question before continuing with this one as they are closely related. Running the proposed code blocks the program at the waitFor invocation. After some research i found that the waitFor method blocks if your process has output that needs to be proccessed so you should first empty the output stream and the error stream. I did those things but my method still blocks. I then found a suggestion to simply loop while waiting the exitValue method to return the exit value of the process and handle the exception thrown if it is not, pausing for a brief moment as well so as not to consume all the CPU. I did this: import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class Test { public static void main(String[] args) { try { Process p = Runtime.getRuntime().exec( "cmd /k start SQLScriptsToRun.bat" + " -UuserName -Ppassword" + " projectName"); final BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream())); final BufferedReader error = new BufferedReader(new InputStreamReader(p.getErrorStream())); new Thread(new Runnable() { @Override public void run() { try { while (input.readLine()!=null) {} } catch (IOException e) { e.printStackTrace(); } } }).start(); new Thread(new Runnable() { @Override public void run() { try { while (error.readLine()!=null) {} } catch (IOException e) { e.printStackTrace(); } } }).start(); int i = 0; boolean finished = false; while (!finished) { try { i = p.exitValue(); finished = true; } catch (IllegalThreadStateException e) { e.printStackTrace(); try { Thread.sleep(500); } catch (InterruptedException e1) { e1.printStackTrace(); } } } System.out.println(i); } catch (IOException e) { e.printStackTrace(); } } } but my process will not end! I keep getting this error: java.lang.IllegalThreadStateException: process has not exited Any ideas as to why my process will not exit? Or do you have any libraries to suggest that handle executing batch files properly and wait until the execution is finished?

  • forkpty - socket

    - by Alexxx
    Hi, I'm trying to develop a simple "telnet/server" daemon which have to run a program on a new socket connection. This part working fine. But I have to associate my new process to a pty, because this process have some terminal capabilities (like a readline). The code I've developped is (where socketfd is the new socket file descriptor for the new input connection) : int masterfd, pid; const char *prgName = "..."; char *arguments[10] = ....; if ((pid = forkpty(&masterfd, NULL, NULL, NULL)) < 0) perror("FORK"); else if (pid) return pid; else { close(STDOUT_FILENO); dup2(socketfd, STDOUT_FILENO); close(STDIN_FILENO); dup2(socketfd, STDIN_FILENO); close(STDERR_FILENO); dup2(socketfd, STDERR_FILENO); if (execvp(prgName, arguments) < 0) { perror("execvp"); exit(2); } } With that code, the stdin / stdout / stderr file descriptor of my "prgName" are associated to the socket (when looking with ls -la /proc/PID/fd), and so, the terminal capabilities of this process doesn't work. A test with a connection via ssh/sshd on the remote device, and executing "localy" (under the ssh connection) prgName, show that the stdin/stdout/stderr fd of this process "prgName" are associated to a pty (and so the terminal capabilities of this process are working fine). What I am doing wrong? How to associate my socketfd with the pty (created by forkpty) ? Thank Alex

  • Append a dynamically changing watermark to a PDF in SharePoint

    - by ccomet
    This is primarily a question of possibilities more than instructions. I'm a programming consultant working on a WSS project site system for my client. We have a document library in which files are uploaded to go through a complex approval process. With multiple stages in this process, we have an extra field which dictates what the current status of the document is. Now, my client has become enamored with the idea of PDF watermarking. He wants the document (which is already a PDF) to be affixed with a watermark corresponding to the current status, such that with each stage of the approval process the watermark will change. One method, the traditional method for PDF watermarking, of accomplishing this is to have one "clean" copy of the document somewhere hidden on the site, and create a new PDF from it that has the watermark at each stage of the approval process. Since the filename will never change, this new PDF can be uploaded continually to a public library, always overwriting the old version and simulating a "dynamically changing watermark". However, in the various stages there will also be people uploading clean copies with corrections and suggestions, nevermind the complex nature of juggling around two libraries and the fact we double the number of files stored. My client and I agree that this is not a practical path to choose. What we would like to do is be able to "modify" the watermark in a PDF, so that we only have to keep one copy of the file. Unfortunately, from what I've seen, in most cases when you make something like a watermark, which in its nature is supposed to be "unmodifyable", you won't be able to edit it later. So, is it possible to have a part of a PDF which cannot be changed by anyone who downloads the file, but can be changed as part of a workflow or other object model process? Thanks in advance!

  • Clojure agents consuming from a queue

    - by erikcw
    I'm trying to figure out the best way to use agents to consume items from a Message Queue (Amazon SQS). Right now I have a function (process-queue-item) that grabs an items from the queue, and processes it. I want to process these items concurrently, but I can't wrap my head around how to control the agents. Basically I want to keep all of the agents busy as much as possible without pulling to many items from the Queue and developing a backlog (I'll have this running on a couple of machines, so items need to be left in the queue until they are really needed). Can anyone give me some pointers on improving my implementation? (def active-agents (ref 0)) (defn process-queue-item [_] (dosync (alter active-agents inc)) ;retrieve item from Message Queue (Amazon SQS) and process (dosync (alter active-agents dec))) (defn -main [] (def agents (for [x (range 20)] (agent x))) (loop [loop-count 0] (if (< @active-agents 20) (doseq [agent agents] (if (agent-errors agent) (clear-agent-errors agent)) ;should skip this agent until later if it is still busy processing (not sure how) (send-off agent process-queue-item))) ;(apply await-for (* 10 1000) agents) (Thread/sleep 10000) (logging/info (str "ACTIVE AGENTS " @active-agents)) (if (> 10 loop-count) (do (logging/info (str "done, let's cleanup " count)) (doseq [agent agents] (if (agent-errors agent) (clear-agent-errors agent))) (apply await agents) (shutdown-agents)) (recur (inc count)))))

But when iis gets multiple requests, are they all processed by the same w3p process? And does this process automaticly use all my processors and cores? And after that: when i start i new thread in my page, this thread still works when the pages is already served to the client. Where does this thread live? also in the w3p.exe process?

  • How should I clean up hung grandchild processes when an alarm trips in Perl?

    - by brian d foy
    I have a parallelized automation script which needs to call many other scripts, some of which hang because they (incorrectly) wait for standard input. That's not a big deal because I catch those with alarm. The trick is to shut down those hung grandchild processes when the child shuts down. I thought various incantations of SIGCHLD, waiting, and process groups could do the trick, but they all block and the grandchildren aren't reaped. My solution, which works, just doesn't seem like it is the right solution. I'm not especially interested in the Windows solution just yet, but I'll eventually need that too. Mine only works for Unix, which is fine for now. I wrote a small script that takes the number of simultaneous parallel children to run and the total number of forks: $ fork_bomb <parallel jobs> <number of forks> $ fork_bomb 8 500 This will probably hit the per-user process limit within a couple of minutes. Many solutions I've found just tell you to increase the per-user process limit, but I need this to run about 300,000 times, so that isn't going to work. Similarly, suggestions to re-exec and so on to clear the process table aren't what I need. I'd like to actually fix the problem instead of slapping duct tape over it. I crawl the process table looking for the child processes and shut down the hung processes individually in the SIGALRM handler, which needs to die because the rest of real code has no hope of success after that. The kludgey crawl through the process table doesn't bother me from a performance perspective, but I wouldn't mind not doing it: use Parallel::ForkManager; use Proc::ProcessTable; my $pm = Parallel::ForkManager->new( $ARGV[0] ); my $alarm_sub = sub { kill 9, map { $_->{pid} } grep { $_->{ppid} == $$ } @{ Proc::ProcessTable->new->table }; die "Alarm rang for $$!\n"; }; foreach ( 0 .. $ARGV[1] ) { print "."; print "\n" unless $count++ % 50; my $pid = $pm->start and next; local $SIG{ALRM} = $alarm_sub; eval { alarm( 2 ); system "$^X -le '<STDIN>'"; # this will hang alarm( 0 ); }; $pm->finish; } If you want to run out of processes, take out the kill. I thought that setting a process group would work so I could kill everything together, but that blocks: my $alarm_sub = sub { kill 9, -$$; # blocks here die "Alarm rang for $$!\n"; }; foreach ( 0 .. $ARGV[1] ) { print "."; print "\n" unless $count++ % 50; my $pid = $pm->start and next; setpgrp(0, 0); local $SIG{ALRM} = $alarm_sub; eval { alarm( 2 ); system "$^X -le '<STDIN>'"; # this will hang alarm( 0 ); }; $pm->finish; } The same thing with POSIX's setsid didn't work either, and I think that actually broke things in a different way since I'm not really daemonizing this. Curiously, Parallel::ForkManager's run_on_finish happens too late for the same clean-up code: the grandchildren are apparently already disassociated from the child processes at that point.

  • "Mem Usage" higher than "VM Size" in WinXP Task Manager

    - by Frederick
    In my Windows XP Task Manager, some processes display a higher value in the Mem Usage column than the VMSize. My Firefox instance, for example shows 111544 K as mem usage and 100576 K as VMSize. According to the help file of Task Manager Mem Usage is the working set of the process and VMSize is the committed memory in the Virtual address space. My question is, if the number of committed pages for a process is A and the number of pages in physical memory for the same process is B, shouldn't it always be B = A? Isn't the number of pages in physical memory per process a subset of the committed pages? Or is this something to do with sharing of memory among processes? Please explain. (Perhaps my definition of 'Working Set' is off the mark). Thanks.
