  • How to access "Custom" or non-System TFS workitem fields using PowerShell?

    - by DaBozUK
    When using PowerShell to extract information from TFS, I find that I can get at the standard fields but not "Custom" fields. I'm not sure custom is the correct term, but for example if I look at the Process Editor in VS2008 and edit the Work Item type, there are fields such as listed below, with Name, Type and RefName: Title String System.Title State String System.State Rev Integer System.Rev Changed By String System.ChangedBy I can access these with Get-TfsItemHistory: Get-TfsItemHistory "$/path" -Version "D01/12/10~" -R | Select -exp WorkItems | Format-Table Title, State, Rev, ChangedBy -Auto So far so good. However, there are also some other fields in the WorkItem type, which I'm calling "Custom" or non-System fields, e.g.: Activated By String Microsoft.VSTS.Common.ActivatedBy Resolved By String Microsoft.VSTS.Common.ResolvedBy And the following command does not retrieve the data, just spaces. Get-TfsItemHistory "$/path" -Version "D01/12/10~" -R | Select -exp WorkItems | Format-Table ActivatedBy, ResolvedBy -Auto I've also tried the names in quotes, the fully qualified refname, but no luck. How do you access these "non-System" fields? Thanks Boz UPDATE: From Keith's answer I can get the fields I need: Get-TfsItemHistory "$/Hermes/Main" -Version "D01/12/10~" -Recurse ` | Select ChangeSetId, Comment -exp WorkItems ` | Select ChangeSetId, Comment, @{n='WI-Id'; e={$_.Id}}, Title -exp Fields ` | Where {$_.ReferenceName -eq 'Microsoft.VSTS.Common.ResolvedBy'} ` | Format-Table ChangesetId, Comment, WI-Id, Title, @{n='Resolved By'; e={$_.Value}} -Auto

  • ORACLE using function parametes in where claus

    - by Gainder
    Hello, I have created a simple static function in oracle 10g to get the reference of an object based on his pk. STATIC FUNCTION getRef(nome IN VARCHAR2) RETURN REF folder_typ IS fl_r REF folder_typ := null; BEGIN SELECT REF(fl) INTO fl_r FROM folder_tab fl WHERE fl.nome = nome; RETURN fl_r; END getRef; This gives me an error because he could't fetch the row. If insted of WHERE fl.nome = nome; I write WHERE fl.nome = 'folder1'; insted of passing it as parameter it works. I think im not using the parameter in the right way. How can I use it?

  • How should I rewrite my code to make it amenable to unittesting?

    - by justin
    I've been trying to get started with unit-testing while working on a little cli program. My program basically parses the command line arguments and options, and decides which function to call. Each of the functions performs some operation on a database. So, for instance, I might have a create function: def create(self, opts, args): #I've left out the error handling. strtime = datetime.datetime.now().strftime("%D %H:%M") vals = (strtime, opts.message, opts.keywords, False) self.execute("insert into mytable values (?, ?, ?, ?)", vals) self.commit() Should my test case call this function, then execute the select sql to check that the row was entered? That sounds reasonable, but also makes the tests more difficult to maintain. Would you rewrite the function to return something and check for the return value? Thanks

  • iphone pushviewcontroller to landscape

    - by satyam
    I've simple iphone application. it has 3 views. first view is portrait view that has 3 buttons. second view has a table view which is also a portrait. In first view, on click of a button second view is shown. on click of a cell in second view, thrid view is shown. but third view is a landscape. I'm using "pushViewController" to navigate from each view. When creating views in IB, first two views are portait and 3rd view is a landscape. In 3rd viewcontroller, i'm using following code as well: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { //return UIInterfaceOrientationIsLandscape(interfaceOrientation); return ((interfaceOrientation == UIInterfaceOrientationLandscapeRight) || (interfaceOrientation == UIInterfaceOrientationLandscapeLeft)); } How can I show first two views in portrait and third view in landscape.

  • iPhone SDK: How do you download video files to the Document Directory and then play them?

    - by Jessica
    I've been fooling around with code for ages on this one, I would be very grateful if someone could provide a code sample that downloaded this file from a server http://www.archive.org/download/june_high/june_high_512kb.mp4, (By the way it's not actually this file, it's just a perfect example for anyone trying to help me) and then play it from the documents directory. I know it seems lazy of me to ask this but I have tried so many different variations of NSURLConnection that it's driving me crazy. Also, if I did manage to get the video file downloaded would I be correct in assuming this code would then successfully play it: NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *path = [documentsDirectory stringByAppendingPathComponent:@"june_high_512kb.mp4"]; NSURL *movieURL = [NSURL fileURLWithPath:path]; self.theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; [_theMovie play]; If the above code would work in playing a video file from the document directory, then I guess the only thing I would need to know is, how to download a video file from a server. Which is what seems to be my major problem. Any help is greatly appreciated.

  • WPF validation red border doesn't show If UserControl collapsed first

    - by Creepy Gnome
    There seems to be a bug with WPF in 3.5, and I was hoping someone may have found a workaround. Basically if you have a custom UserControl that contains a TextBox and it is in a Window but initialized to be Collapsed by default in the xaml or code behind if it fails validation when you make the control visible it will not show the red border until it fails while visible. However, this works correctly when visibility is set to Hidden, just no when Collapsed. I am already overriding the ErrorTemplate with a style to workaround the Adornment issue with the red border staying visibile when you collapse the control. Below is my full style for the TextBox. If there is any additional changes or additions to make it work correctly with collapsed controls that would be great. <Style TargetType="TextBox"> <Setter Property="Margin" Value="3" /> <Setter Property="Validation.ErrorTemplate"> <Setter.Value> <ControlTemplate> <ControlTemplate.Resources> <BooleanToVisibilityConverter x:Key="converter" /> </ControlTemplate.Resources> <DockPanel LastChildFill="True"> <Border BorderThickness="2" BorderBrush="Red" Visibility="{ Binding ElementName=placeholder, Mode=OneWay, Path=AdornedElement.IsVisible, Converter={StaticResource converter}}" > <AdornedElementPlaceholder x:Name="placeholder" /> </Border> </DockPanel> </ControlTemplate> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true" > <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}" /> </Trigger> </Style.Triggers> </Style>

  • Simple Python Challenge: Fastest Bitwise XOR on Data Buffers

    - by user213060
    Challenge: Perform a bitwise XOR on two equal sized buffers. The buffers will be required to be the python str type since this is traditionally the type for data buffers in python. Return the resultant value as a str. Do this as fast as possible. The inputs are two 1 megabyte (2**20 byte) strings. The challenge is to substantially beat my inefficient algorithm using python or existing third party python modules (relaxed rules: or create your own module.) Marginal increases are useless. from os import urandom from numpy import frombuffer,bitwise_xor,byte def slow_xor(aa,bb): a=frombuffer(aa,dtype=byte) b=frombuffer(bb,dtype=byte) c=bitwise_xor(a,b) r=c.tostring() return r aa=urandom(2**20) bb=urandom(2**20) def test_it(): for x in xrange(1000): slow_xor(aa,bb)

  • Angularjs togglecheck error(not working as intended) with prechecked data

    - by crozzfire
    I have this plunker where i have a button that opens a bootstrap modal dialog box. I the modal, when a course is selected(checked) from this list, it adds 3 to the $scope.planned and also increases the progress bar accordingly. Similarly it also reduces in the same way when a checkbox is unchecked. This is the function that does the above: $scope.toggleCheck = function (course) { //debugger var x = $scope.checkcoursefunction($scope.selectedCourses, course); if(x==true){ $scope.selectedCourses.splice($scope.selectedCourses.indexOf(course), 1); $scope.planned -= 3; } else{ if ($scope.selectedCourses.indexOf(course) === -1){ $scope.selectedCourses.push(course); $scope.planned += 3; } else { $scope.selectedCourses.splice($scope.selectedCourses.indexOf(course), 1); $scope.planned -= 3; } } $scope.getPercentage(); }; I have 2 services from where the controller fetches its data named Requirements and Planned Services. The table in the modal has a list of the requirements service data. I also have a function named checkplanneddetails() that checks if an item from this data is present in the requirements data. If present, they come in the table pre-checked. This is the function that checks: $scope.checkplanneddetails = function(course){ $scope.coursedetail = course; $scope.requirementcoursename = ($scope.coursedetail.course.subject).concat("-",$scope.coursedetail.course.course_no); for(var k = 0; k < $scope.planneddetails.length; k++){ if($scope.requirementcoursename==$scope.planneddetails[k].course_name){ $scope.selectedCourses.push(course); return true; } } return false; }; $scope.checkcoursefunction = function(arr,obj){ return (arr.indexOf(obj) != -1); } This works fine with bringing the data as checked. But the togglecheck() function does not work as they are supposed to with these checked details(they work in reverse). It always returns true(for var x in togglecheck) even after the splice function. Am i splicing the course correctly?

  • Implicit and Explicit implementation of interface.

    - by Amby
    While working on a upgrade i happened to come across a code like this. interface ICustomization { IMMColumnsDefinition GetColumnsDefinition(); } class Customization : ICustomization { private readonly ColumnDefinition _columnDefinition; //More code here. public ColumnsDefinition GetColumnsDefinition() { return _columnDefinition; } ColumnsDefinition ICustomization.GetColumnsDefinition() //redundant { return GetColumnsDefinition(); } } My question is: Is there any need/use of 'explicit' implementation of interface in this piece of code? Will it create any problem if i remove the method (explicit implementation of interface) that i have marked "redundant" above? PS: I understand that explicit implementation of interface is very important, and it can be used when we need to give access to a method at interface level only, and to use two interface with same signature of method.

  • Git Diff with Beyond Compare

    - by Avanst
    I have succeeded in getting git to start Beyond Compare 3 as a diff tool however, when I do a diff, the file I am comparing against is not being loaded. Only the latest version of the file is loaded and nothing else, so there is nothing in the right pane of Beyond Compare. I am running git 1.6.3.1 with Cygwin with Beyond Compare 3. I have set up beyond compare as they suggest in the support part of their website with a script like such: #!/bin/sh # diff is called by git with 7 parameters: # path old-file old-hex old-mode new-file new-hex new-mode "path_to_bc3_executable" "$2" "$5" | cat Has anyone else encountered this problem and know a solution to this? Edit: I have followed the suggestions by VonC but I am still having exactly the same problem as before. I am kinda new to Git so perhaps I am not using the diff correctly. For example, I am trying to see the diff on a file with a command like such: git diff main.css Beyond Compare will then open and only display my current main.css in the left pane, there is nothing in the right pane. I would like the see my current main.css in the left pane compared to the HEAD, basically what I have last committed. My git-diff-wrapper.sh looks like this: #!/bin/sh # diff is called by git with 7 parameters: # path old-file old-hex old-mode new-file new-hex new-mode "c:/Program Files/Beyond Compare 3/BCompare.exe" "$2" "$5" | cat My git config looks like this for Diff: [diff] external = c:/cygwin/bin/git-diff-wrapper.sh

  • Content type - Restlet

    - by DutrowLLC
    How do you set the content type in Restlet (version 2.0 for google app engine)? In this case, I'd like to set the content type to ""text/xml". I have: public class SubResource extends ServerResource { @Get public Representation get(Representation representation){ setStatus(Status.SUCCESS_OK); StringRepresentation sr = new StringRepresentation(getSomeXml()); return sr; } } I'm unsure even if it is a value that is set in the Representation, or if it is set from the ServerResource class the same way that the return code is. ANSWER: StringRepresentation sr = new StringRepresentation(getSomeXml()); sr.setMediaType(MediaType.TEXT_XML);

  • Debugging a HTTP Handler from Visual Studio

    - by O.O.
    I am trying to debug a HTTP Handler in Visual Studio and the break point is not getting hit. Does anyone have an idea on how to go about debugging HTTP Handlers in Visual Studio? I am using VS 2010 Premium, .NET 4.0 on a Windows 7 machine. In my Web Application I have a HTTP Handler in /HTTPHandler/TrackingHandler.cs The following is in my web config file: <system.webServer> <handlers> <add name="TrackingHandler" path="/tx/*" verb="*" type="ProjectNamespace.TrackingHandler" resourceType="Unspecified" preCondition="integratedMode" /> </handlers> </system.webServer> My HTTP Handler looks like below namespace ProjectNamespace { public class TrackingHandler : IHttpHandler { public bool IsReusable { get { return true; } } public void ProcessRequest(HttpContext context) { //Breakpoint on the very first line below string tracker = Path.GetFileName(context.Request.PhysicalPath); ....... } } } I start my Web Application using any random page in Visual Studio Debug using the builtin Web Server. I then maually edit the URL to point to the /tx/ directory and some random string after it. For e.g. my current URL looks like http://localhost:53699/tx/sdfs. I thought this should pull up the breakpoint on the first line of ProcessRequest() but it does not. I’d be grateful for any ideas. O. O.

  • Passing additional arguments into the OnClick event handler of a LinkButton using Javascript

    - by Jens Ameskamp
    Hi! I have a ASP.NET Website, where, in a GridView item template, automatically populated by a LinqDataSource, there is a LinkButton defined as follows: <asp:LinkButton ID="RemoveLinkButton" runat="server" CommandName="Remove" CommandArgument='<%# DataBinder.GetPropertyValue(GetDataItem(), "Id")%>' OnCommand="removeVeto_OnClick" OnClientClick='return confirm("Are you sure?");' Text="Remove Entry" /> This works fine. Whenever the Button is Clicked, a confirmation dialog is displayed. What I am trying to do now, is to allow the user to enter a reason for the removal, and pass this on the the OnClick event handler. How would I do this? I tried OnClientClick='return prompt("Enter your reason!");', but, of course, that did not work =)

  • ANDing javascript objects together

    - by Jonas
    I ran across this chunk of code (modified) in our application, and am confused to how it works: function someObject() { this.someProperty = {}; this.foo = { bar: { baz: function() { return "Huh?" } } }; this.getValue = function() { return (this.someProperty && this.foo.bar && this.foo.bar.baz && this.foo.bar.baz()) || null; } } function test() { var o = new someObject(); var val = o.getValue(); alert(val); } when you call the test() function, the text "Huh?" is alerted. I'm not sure how the result of getValue is returning that, I would've thought doing A && B && C && D would have returned true, rather than the value of D.

  • highlighting words at the end of a word

    - by fusion
    i'm not sure how i could have phrased the title better, but my issue is that the highlight function doesn't highlight the search keywords which are at the end of the word. for example, if the search keyword is 'self', it will highlight 'self' or 'self-lessness' or 'Self' [with capital S] but it will not highlight the self of 'yourself' or 'himself' etc. . this is my highlight function: function highlightWords($text, $words) { preg_match_all('~\w+~', $words, $m); if(!$m) return $text; $re = '~\\b(' . implode('|', $m[0]) . ')~i'; $string = preg_replace($re, '<span class="highlight">$0</span>', $text); return $string; }

  • Prim's MST algorithm implementation with Java

    - by user1290164
    I'm trying to write a program that'll find the MST of a given undirected weighted graph with Kruskal's and Prim's algorithms. I've successfully implemented Kruskal's algorithm in the program, but I'm having trouble with Prim's. To be more precise, I can't figure out how to actually build the Prim function so that it'll iterate through all the vertices in the graph. I'm getting some IndexOutOfBoundsException errors during program execution. I'm not sure how much information is needed for others to get the idea of what I have done so far, but hopefully there won't be too much useless information. This is what I have so far: I have a Graph, Edge and a Vertex class. Vertex class mostly just an information storage that contains the name (number) of the vertex. Edge class can create a new Edge that has gets parameters (Vertex start, Vertex end, int edgeWeight). The class has methods to return the usual info like start vertex, end vertex and the weight. Graph class reads data from a text file and adds new Edges to an ArrayList. The text file also tells us how many vertecis the graph has, and that gets stored too. In the Graph class, I have a Prim() -method that's supposed to calculate the MST: public ArrayList<Edge> Prim(Graph G) { ArrayList<Edge> edges = G.graph; // Copies the ArrayList with all edges in it. ArrayList<Edge> MST = new ArrayList<Edge>(); Random rnd = new Random(); Vertex startingVertex = edges.get(rnd.nextInt(G.returnVertexCount())).returnStartingVertex(); // This is just to randomize the starting vertex. // This is supposed to be the main loop to find the MST, but this is probably horribly wrong.. while (MST.size() < returnVertexCount()) { Edge e = findClosestNeighbour(startingVertex); MST.add(e); visited.add(e.returnStartingVertex()); visited.add(e.returnEndingVertex()); edges.remove(e); } return MST; } The method findClosesNeighbour() looks like this: public Edge findClosestNeighbour(Vertex v) { ArrayList<Edge> neighbours = new ArrayList<Edge>(); ArrayList<Edge> edges = graph; for (int i = 0; i < edges.size() -1; ++i) { if (edges.get(i).endPoint() == s.returnVertexID() && !visited(edges.get(i).returnEndingVertex())) { neighbours.add(edges.get(i)); } } return neighbours.get(0); // This is the minimum weight edge in the list. } ArrayList<Vertex> visited and ArrayList<Edges> graph get constructed when creating a new graph. Visited() -method is simply a boolean check to see if ArrayList visited contains the Vertex we're thinking about moving to. I tested the findClosestNeighbour() independantly and it seemed to be working but if someone finds something wrong with it then that feedback is welcome also. Mainly though as I mentioned my problem is with actually building the main loop in the Prim() -method, and if there's any additional info needed I'm happy to provide it. Thank you. Edit: To clarify what my train of thought with the Prim() method is. What I want to do is first randomize the starting point in the graph. After that, I will find the closest neighbor to that starting point. Then we'll add the edge connecting those two points to the MST, and also add the vertices to the visited list for checking later, so that we won't form any loops in the graph. Here's the error that gets thrown: Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 0, Size: 0 at java.util.ArrayList.rangeCheck(Unknown Source) at java.util.ArrayList.get(Unknown Source) at Graph.findClosestNeighbour(graph.java:203) at Graph.Prim(graph.java:179) at MST.main(MST.java:49) Line 203: return neighbour.get(0); in findClosestNeighbour() Line 179: Edge e = findClosestNeighbour(startingVertex); in Prim()

  • Agilent E4426B signal generator locks up during multiple GPIB *SAV operations

    - by aspiehler
    I have a test fixture with an Agilent E4426B RF signal generator connected to a PC via a National Instrument Ethernet-to-GPIB bridge. My software is attempting to sanitize the instrument by presetting it and then saving the current state to all of the memory locations writable via the standard SCPI command "*SAV x,y". The loop works to a point, but eventually the instrument responds with an error and continuously displays the "L" icon on the front display and a "Remote preset" message at the bottom. At that point it won't respond to any more remote commands and I have to either cycle power or press LOCAL, then PRESET at which point it takes about 3 minutes to finish presetting. At that point the "L" icon is still present and and the next GPIB command sent to the instrument causes it to report a -113 error (undefined header) in the instrument error queue. I fired up NI spy to see what was happening, and found that the error was happening at the same point in the loop - "*SAV 6,2" in this case. From NI Spy: Send (0, 0x0017, "*SAV 6,2", 8 (0x8), NLend (0,0x01)) Process ID: 0x00000520 Thread ID: 0x00000518 ibsta:0xc168 iberr: 6 ibcntl: 2(0x2) And here's the code from the instrument driver: int CHP_E4426b::Erase() { if ((m_StatusCode = Initialize()) != GPIB_SUCCESS) // basically just sends "*RST" return m_StatusCode; m_SaveState = "*SAV %d, %d"; for (int i=0; i < 10; i++) for (int j=0; j < 100; j++) { sprintf(m_CmdString, m_SaveState, j, i); if ((m_StatusCode = Send(m_CmdString, strlen(m_CmdString))) != GPIB_SUCCESS) return m_StatusCode; } return GPIB_SUCCESS; } I tried putting a small Sleep() delay (10-20 ms) at the end of the inner loop, and to my surprise it caused the error to show up earlier rather than later. 10 ms caused the loop to error out at 44,1 and 20 ms was even sooner. I've already eliminated faulty cabling or the instrument as the culprit. This same type of sequence works without any error on a higher end signal generator, so I'm tempted to chalk this up to a bug in the instrument's firmware.

At the last record i have a such file pointer: `fp 0x10311448 {_ptr=0x00344b90 "???????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? _ _iobuf * ` And i read last record 2 times... Save file code: void * dbClose(Database *db) { FILE *fp = fopen(FileNameS, "w+b"); List *lst, *temp; lst = db->head; while(lst != NULL) { fwrite(lst->s, sizeof(*(lst->s)), 1, fp); temp = lst; lst = lst->next; free(temp); } free(db); fclose(fp); }

  • Resharper Split String literal

    - by Ismael
    I was not lucky in my 15 minutes googling. Maybe bad luck with good keyword? Why does the Resharper suggest spliting a string in function parameter? Example: From this: return PartialView("Categorias", lista); To this: return PartialView("Cat" + "egorias", lista); I checked documentation here: link And it says: Split string literal - Splits string literal into two literals. I want to discover why is this a good practice, what are the fundamental idealogic behind the scenes that achieved this practice. I don't want to do it without knowing why... Help is soooo appreciated.
