  • How do I change the CellErrorStyle for an Xceed Datagrid?

    - by Bob
    So in the Xceed documentation there is a code example that does not work for me. It may be because my grid is bound to a DataGridCollectionView. The objects in the collection used by the datagridcollection are what implement IDataErrorInfo. The errors are showing up just fine. The problem is that they are using the default orange background for errors...I need a red border. Below is the XAML instantiation of my grid. I set the DataCell background property to red just so I could be sure I had access to the grid's properties... I do. I just can't find the way to identify the cell's w/ errors so I can style them. Thanks! <XceedDG:DataGridControl Grid.Row="1" Grid.ColumnSpan="5" ItemsSource="{Binding Path = ABGDataGridCollectionView, UpdateSourceTrigger=PropertyChanged}" Background="{x:Static Views:DataGridControlBackgroundBrushes.ElementalBlue}" IsDeleteCommandEnabled="True" FontSize="16" AutoCreateColumns="False" x:Name="EncounterDataGrid" AllowDrop="True"> <XceedDG:DataGridControl.View> <Views:TableView ColumnStretchMode="All" ShowRowSelectorPane="True" ColumnStretchMinWidth="100"> <Views:TableView.FixedHeaders> <DataTemplate> <XceedDG:InsertionRow Height="40"/> </DataTemplate> </Views:TableView.FixedHeaders> </Views:TableView> </XceedDG:DataGridControl.View> <!--Group Header formatting--> <XceedDG:DataGridControl.Resources> <Style TargetType="{x:Type XceedDG:GroupByControl}"> <Setter Property="Visibility" Value="Collapsed"/> </Style> <Style TargetType="{x:Type XceedDG:DataCell}"> <Setter Property="Background" Value="Red"/> </Style> </XceedDG:DataGridControl.Resources> ...

  • How to use boost::bind with non-copyable params, for example boost::promise ?

    - by zhengxi
    Some C++ objects have no copy constructor, but have move constructor. For example, boost::promise. How can I bind those objects using their move constructors ? #include <boost/thread.hpp> void fullfil_1(boost::promise<int>& prom, int x) { prom.set_value(x); } boost::function<void()> get_functor() { // boost::promise is not copyable, but movable boost::promise<int> pi; // compilation error boost::function<void()> f_set_one = boost::bind(&fullfil_1, pi, 1); // compilation error as well boost::function<void()> f_set_one = boost::bind(&fullfil_1, std::move(pi), 1); // PS. I know, it is possible to bind a pointer to the object instead of // the object itself. But it is weird solution, in this case I will have // to take cake about lifetime of the object instead of delegating that to // boost::bind (by moving object into boost::function object) // // weird: pi will be destroyed on leaving the scope boost::function<void()> f_set_one = boost::bind(&fullfil_1, boost::ref(pi), 1); return f_set_one; }

  • Valueurl Binding On Large Arrays Causes Sluggish User Interface

    - by Hooligancat
    I have a large data set (some 3500 objects) that returns from a remote server via HTTP. Currently the data is being presented in an NSCollectionView. One aspect of the data is a path pack to the server for a small image that represents the data (think thumbnail for simplicity). Bindings works fantastically for the data that is already returned, and binding the image via a valueurl binding is easy to do. However, the user interface is very sluggish when scrolling through the data set - which makes me think that the NSCollectionView is retrieving all the image data instead of just the image data used to display the currently viewable images. I was under the impression that Cocoa controls were smart enough to only retrieve data for the information that is actually being output to the user interface through lazy loading. This certainly seems to be the case with NSTableView - but I could be misguided on this thought. Should valueurl binding act lazily and, moreover, should it act lazily in an NSCollectionView? I could create a caching mechanism (in fact I already have such a thing in place for another application - see my post here if you are interested http://stackoverflow.com/questions/1740209/populating-nsimage-with-data-from-an-asynchronous-nsurlconnection) but I really don't want to go this route if I don't have to for this specific implementation as the user could potentially change data sets often and may only want small sub-sets of the data. Any suggested approaches? Thanks!

  • How to display data stored in core data in a table view?

  • Microsoft Solver Foundation constraint

    - by emaster70
    Hello, I'm trying to use Microsoft Solver Foundation 2 to solve a fairly complicated situation, however I'm stuck with an UnsupportedModelException even when I dumb down the model as much as possible. Does anyone have an idea of what I'm doing wrong? Following is the least example required to reproduce the problematic behavior. var ctx = SolverContext.GetContext(); var model = ctx.CreateModel(); var someConstant = 1337.0; var decisionA = new Decision(Domain.Real, "decisionA"); var decisionB = new Decision(Domain.Real, "decisionB"); var decisionC = new Decision(Domain.Real, "decisionC"); model.AddConstraint("ca", decisionA <= someConstant); model.AddConstraint("cb", decisionB <= someConstant); model.AddConstraint("cc", decisionC <= someConstant); model.AddConstraint("mainConstraint", Model.Equal(Model.Sum(decisionA, decisionB, decisionC), someConstant)) model.AddGoal("myComplicatedGoal", GoalKind.Minimize, decisionC); var solution = ctx.Solve(); solution.GetReport().WriteTo(Console.Out); Console.ReadKey(); Please consider that my actual model should include, once complete, a few constraints in the form of a*a+b*a <= someValue, so if what I'm willing to do ultimately isn't supported, please let me know in advance. If that's the case I'd also appreciate a suggestion of some other solver with a .NET friendly interface that I could use (only well-known commercial packages, please). Thanks in advance

  • Import package problem in GWT

    - by Krt_Malta
    Hi! I'm developing an app using GWT Eclipse plug-in. (I'm also using GWT Designer but I don't think the problem is here). Previously when I wanted to communicate with a web service I created, I produced the "skeleton" classes from the WSDL url using Sun's wsimport tool. Then I would add the classes generated to a class folder in my Eclipse project. All worked well. However this doesn't seem to be working with GWT. I have these: VideoTutorialServiceService service = new VideoTutorialServiceService(); VideoTutorialService port = service.getVideoTutorialServicePort(); and I have VideoTutorialServiceService and VideoTutorialService underlined in red, the error saying videotutorialservice.VideoTutorialServiceService can not be found in source packages. Check the inheritance chain from your module; it may not be inheriting a required module or a module may not be adding its source path entries properly. .... I googled about it but I got confused. I'm a beginnier in GWT. How can I resolve this please? Thanks and regards, Krt_Malta

  • Custom types as key for a map - C++

    - by Appu
    I am trying to assign a custom type as a key for std::map. Here is the type which I am using as key. struct Foo { Foo(std::string s) : foo_value(s){} bool operator<(const Foo& foo1) { return foo_value < foo1.foo_value; } bool operator>(const Foo& foo1) { return foo_value > foo1.foo_value; } std::string foo_value; }; When used with std::map, I am getting the following error. error C2678: binary '<' : no operator found which takes a left-hand operand of type 'const Foo' (or there is no acceptable conversion) c:\program files\microsoft visual studio 8\vc\include\functional 143 If I change the struct like the below, everything worked. struct Foo { Foo(std::string s) : foo_value(s) {} friend bool operator<(const Foo& foo,const Foo& foo1) { return foo.foo_value < foo1.foo_value; } friend bool operator>(const Foo& foo,const Foo& foo1) { return foo.foo_value > foo1.foo_value; } std::string foo_value; }; Nothing changed except making the operator overloads as friend. I am wondering why my first code is not working? Any thoughts?

  • Linker flags for one library break loading of another

    - by trevrosen
    I'm trying to use FMOD and HTTPriot in the same app. FMOD works fine until I add in linker flags for HTTPriot, at which point I get a bunch of linking errors wherein FMOD is complaining about undefined symbols. In other words, adding in linker flags for HTTPriot seems to break the loading of FMOD's library. These are the kinds of errors I'm getting, all coming during the linking phase of my build: Undefined symbols: "_FMOD_Sound_Lock", referenced from: -[FMODEngine recordedSoundAsNSData] in FMODEngine.o -[FMODEngine writeRecordingToDiskWithName:] in FMODEngine.o "_FMOD_MusicSystem_PrepareCue", referenced from: -[FMODEngine addCue:] in FMODEngine.o These are the linker flags for HTTPriot: -lhttpriot -lxml2 -ObjC -all_load I added those as well as a path to the HTTPriot SDK per the instructions here: http://labratrevenge.com/httpriot/docs/iphone-setup.html I was hoping someone could enlighten me on why adding linker flags for one library might cause a failure of another to load. If I DON'T have these flags in, HTTPriot and FMOD both work fine on the simulator, but HTTPriot has runtime errors on the device, I assume because its libraries are not linked. FMOD works fine on the device though. I placed header search paths and library search paths in my build settings in order for XCode to find FMOD. That seemed to be OK until I tried adding these HTTPriot linker flags. I also tried adding a linker flag for the FMOD library (-lfmodex), but I get the same errors as I do without it.

  • broken SQL 2008 SP1 Web Edition (can not login with SSMS)

    - by gerryLowry
    Scenario: My installation of SQL Server 2008 Web Edition SP1 was working properly. Since I've recently joined Microsoft's Website Spark*, I removed SQL2008 and installed SQL 2008 again using my Website Spark edition and license from the MSDN download site. Next, I updated SQL 2008 to SP1 (this is required because I'm running Windows 2008 Server R2 Web edition). When I launch SSMS (SQL Server Management Studio), "User name" is "myhost\Administrator" and is greyed out so it can not be changed. When I installed my Website Spark version, I did not include "myhost\Administrator" when I was configuring SQL 2008 service accounts. Instead I created an administrator account "myhost\mySQLaccount". ERROR MESSAGE: Connect to Server (X) Cannot connect to (local) Additional information: Login failed for user 'myhost'Admistrator' (Microsoft SQL Server, Error: 18456) I tried to use the SQL Server Configuration Manager to correct this problem but could not find any useful way to fix this issue.

  • deepcopy and python - tips to avoid using it?

    - by blackkettle
    Hi, I have a very simple python routine that involves cycling through a list of roughly 20,000 latitude,longitude coordinates and calculating the distance of each point to a reference point. def compute_nearest_points( lat, lon, nPoints=5 ): """Find the nearest N points, given the input coordinates.""" points = session.query(PointIndex).all() oldNearest = [] newNearest = [] for n in xrange(nPoints): oldNearest.append(PointDistance(None,None,None,99999.0,99999.0)) newNearest.append(obj2) #This is almost certainly an inappropriate use of deepcopy # but how SHOULD I be doing this?!?! for point in points: distance = compute_spherical_law_of_cosines( lat, lon, point.avg_lat, point.avg_lon ) k = 0 for p in oldNearest: if distance < p.distance: newNearest[k] = PointDistance( point.point, point.kana, point.english, point.avg_lat, point.avg_lon, distance=distance ) break else: newNearest[k] = deepcopy(oldNearest[k]) k += 1 for j in range(k,nPoints-1): newNearest[j+1] = deepcopy(oldNearest[j]) oldNearest = deepcopy(newNearest) #We're done, now print the result for point in oldNearest: print point.station, point.english, point.distance return I initially wrote this in C, using the exact same approach, and it works fine there, and is basically instantaneous for nPoints<=100. So I decided to port it to python because I wanted to use SqlAlchemy to do some other stuff. I first ported it without the deepcopy statements that now pepper the method, and this caused the results to be 'odd', or partially incorrect, because some of the points were just getting copied as references(I guess? I think?) -- but it was still pretty nearly as fast as the C version. Now with the deepcopy calls added, the routine does it's job correctly, but it has incurred an extreme performance penalty, and now takes several seconds to do the same job. This seems like a pretty common job, but I'm clearly not doing it the pythonic way. How should I be doing this so that I still get the correct results but don't have to include deepcopy everywhere?

  • How do I process the configure file when cross-compiling with mingw?

    - by vy32
    I have a small open source program that builds with an autoconf configure script. I ran configure I tried to compile with: make CC="/opt/local/bin/i386-mingw32-g++" That didn't work because the configure script found include files that were not available to the mingw system.

  • question regarding templatization of virtual function

    - by jan
    Hi, I am new to this forum and sorry If I am repeating this question. I know that you cannot templatize the virtual function and I do understand the concept behind it. But I still need a way to get across some errors I am getting it. I am able to make my stuff work but it doesn't look to me. Here's the deal, I have class called System, #include "Vector.h" class System { virtual void VectorToLocal(Vector<T>& global_dir,const Vector<T>* global_pos = 0) const = 0; }; class UnresolvedSystem : public System { virtual void VectorToLocal(Vector<T>& global_dir,const Vector<T>* global_pos = 0) const { //do something } }; In Vector.h tenplate<typename T> class Vector { //some functions }; See now I want to templatize VectorToLocal in system.h to take just Vector, but I cannot do it as it is a virtual function. I want a work around. I know I can have VectorToLocal take Vector, Vector etc as arguments. But I do not want to do it. Any help would be really appreciated. Thanks in advance, Jan

  • Cannot upload media via Wordpress uploader

    - by Justin Johnson
    This has to do with media uploading in Wordpress. Every time WP creates a folder for new uploads (it organizes uploads by year and month: yyyy/mm), it creates it with the "apache:apache' user and group, with full access to all (777 or drwxrwxrwx). However, after that, WP cannot create a folder within that folder (e.g.: mkdir 2011 succeeds, but mkdir 2011/01 fails). Also, uploads cannot be moved into these newly created folders even though the permissions are 777 (rwxrwxrwx). Once a month, I have to chown the newly created folders to be the same as user:group as the rest of the files. Once I do that, uploading works fine (which doesn't make sense to me The really frustrating part is that this problem doesn't exist in other WP installs on other domains on the same server. * I wasn't sure if this should be here or on serverfault. Edit: The containing directory /.../httpdocs/blog/wp-content/uploads has the correct ownership drwxrwxrwx 5 myuser psaserv 4096 Jun 3 18:38 uploads This is a Plesk/CentOS environment hosted by Media Temple (dv). I've written the following test script to simulate the problem <pre><?php $d = "d" . mt_rand(100, 500); var_dump( get_current_user(), $d, mkdir($d), chmod($d, 0777), mkdir("$d/$d"), chmod("$d/$d", 0777), fileowner($d), getmyuid() ); The script always creates the first directory mkdir($d) successfully. On domain A, where the WP problem is, it cannot create the nested directory mkdir("$d/$d"). However, on domain B, both directories are successfully created. I am running each script at /var/www/vhosts/domainA/httpdocs/tmp/t.php and /var/www/vhosts/domainB/httpdocs/tmp/t.php respectively I checked the permissions on tmp, httpdocs, and domain[AB] and they are the same for each path. The only thing that differs is the user.

  • Classification: Dealing with Abstain/Rejected Class

    - by abner.ayala
    I am asking for your input and/help on a classification problem. If anyone have any references that I can read to help me solve my problem even better. I have a classification problem of four discrete and very well separated classes. However my input is continuous and has a high frequency (50Hz), since its a real-time problem. The circles represent the clusters of the classes, the blue line the decision boundary and Class 5 equals the (neutral/resting do nothing class). This class is the rejected class. However the problem is that when I move from one class to the other I activate a lot of false positives in the transition movements, since the movement is clearly non-linear. For example, every time I move from class 5 (neutral class) to 1 I first see a lot of 3's before getting to the 1 class. Ideally, I will want my decision boundary to look like the one in the picture below where the rejected class is Class =5. Has a higher decision boundary than the others classes to avoid misclassification during transition. I am currently implementing my algorithm in Matlab using naive bayes, kNN, and SVMs optimized algorithms using Matlab. Question: What is the best/common way to handle abstain/rejected classes classes? Should I use (fuzzy logic, loss function, should I include resting cluster in the training)?

  • max file upload size change in web.config

    - by Christopher Johnson
    using .net mvc 3 and trying to increase the allowable file upload size. This is what I've added to web.config: <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <modules runAllManagedModulesForAllRequests="true"> <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah" preCondition="managedHandler" /> <add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah" preCondition="managedHandler" /> <add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah" preCondition="managedHandler" /> </modules> <handlers> <add name="Elmah" path="elmah.axd" verb="POST,GET,HEAD" type="Elmah.ErrorLogPageFactory, Elmah" preCondition="integratedMode" /> </handlers> <security> <requestFiltering> <requestLimits maxAllowedContentLength="104857600"/> </requestFiltering> </security> *ignore the elmah stuff. it's still not allowing file sizes larger than 50MB and this should allow up to 100MB no? any ideas?

  • How to rename an existing Grails application

    - by Johan Pelgrim
    Hi there, Does anybody know how to (easily) "rename" an existing grails application? I'm running into this because my PaaS provider does not allow me to delete a subscription... So I want to deploy my application under a different name. Of course, I can do this manually, but I think it might be a useful 'top-level' script (i.e. "grails rename-app newappname") Manual hints: When I do a "grails create-app myappname" I can see the myappname exists in the following files (and filenames)... Of course this is done by the create-app script, which replaces @...@ tokens in the template. I guess once they are replaced, it's not trivial to do a rename. ./.project: <name>myappname</name> ./application.properties:app.name=myappname ./build.xml:<project xmlns:ivy="antlib:org.apache.ivy.ant" name="myappname" default="test"> ./ivy.xml: <info organisation="org.example" module="myappname"/> ./myappname-test.launch:<stringAttribute key="org.eclipse.jdt.launching.PROJECT_ATTR" value="myappname"/> ./myappname.launch:<listEntry value="/myappname"/> ./myappname.launch:<listEntry value="<?xml version="1.0" encoding="UTF-8"?> <runtimeClasspathEntry containerPath="org.eclipse.jdt.launching.JRE_CONTAINER" javaProject="myappname" path="1" type="4"/> "/> ./myappname.launch:<stringAttribute key="org.eclipse.jdt.launching.PROJECT_ATTR" value="myappname"/> ./myappname.launch:<stringAttribute key="org.eclipse.jdt.launching.VM_ARGUMENTS" value="-Dbase.dir="${project_loc:myappname}" -Dserver.port=8080 -Dgrails.env=development"/> ./myappname.tmproj: <string>myappname.launch</string> And of course... the top-level directory name is "myappname" Any hints, or information about ongoing initiatives in this area are welcome Greetz, Johan

  • How can I use Django with MySQL in MAMP stack?

    - by Robert A Henru
    Hi all, I have difficulty especially in installing MySQLdb module (MySQL-python-1.2.3c1), to connect to the MySQL in MAMP stack. I've done a number of things such as copying the mysql include directory and library (including plugin) from a fresh installation of mysql (version 5.1.47) to the one inside MAMP (version 5.1.37). Now, the MySQLdb module build and install doesnt give me error. The error happens when I'm calling 'import MySQLdb' from python shell (version 2.6). Traceback (most recent call last): File "<stdin>", line 1, in <module> File "build/bdist.macosx-10.6-universal/egg/MySQLdb/__init__.py", line 19, in <module> File "build/bdist.macosx-10.6-universal/egg/_mysql.py", line 7, in <module> File "build/bdist.macosx-10.6-universal/egg/_mysql.py", line 6, in __bootstrap__ ImportError: dlopen(/Users/rhenru/.python-eggs/MySQL_python-1.2.3c1-py2.6-macosx-10.6-universal.egg-tmp/_mysql.so, 2): Symbol not found: _mysql_affected_rows Referenced from: /Users/rhenru/.python-eggs/MySQL_python-1.2.3c1-py2.6-macosx-10.6-universal.egg-tmp/_mysql.so Expected in: flat namespace in /Users/rhenru/.python-eggs/MySQL_python-1.2.3c1-py2.6-macosx-10.6-universal.egg-tmp/_mysql.so Any idea, what else do I need to do to make it works? Thanks a bunch, Robert

  • Compare sign of two doubles

    - by bobobobo
    What's the fastest way to compare sign on a double? I know that a double has a "sign bit" but I'm not sure if the way I'm "looking for it" in its binary rep is a good idea or not. Barring "portability" issues, can someone tell me what's going on with this code in MSVC++? #include <stdio.h> int main() { double z = 5.0 ; __int64 bitSign ; __int64 *ptr ; ptr = (__int64*)&z ; for( __int64 sh = 0 ; sh < 65 ; sh++ ) { bitSign = 1L << sh ; // Weird. it doesn't do 1. printf( "Bit# %d (%llx): %lld\n", sh, bitSign, ( (*ptr) & bitSign) ) ; } } First, why is starting at bit 32, even though I only shifted by one bit? Second, is it ok for me to check the 64th bit of a double to check its sign on MSVC++? Or is there a more preferred way?

  • How to verify the SSL connection when calling an URI?

    - by robertokl
    Hello, I am developing an web application that is authenticated using CAS (A single-sign-on solution: http://www.ja-sig.org/wiki/display/CAS/Home). For security reasons, I need two things to work: The communication between CAS and my application needs to be secure My application needs to accept the certification coming with CAS, so that I can guarantee that the CAS responding is the real CAS Server. This is what I got so far: uri = URI.parse("https://www.google.com/accounts") https = Net::HTTP.new(uri.host, uri.port) https.use_ssl = (uri.scheme == 'https') https.verify_mode = (OpenSSL::SSL::VERIFY_PEER) raw_res = https.start do |conn| conn.get("#{uri.path}?#{uri.query}") end This works just great in my Mac OSX. When I try to reach an insecure uri, it raises an exception, and when I try to reach a secure uri, it allow me normally, just like expected. The problem starts when I deploy my application on my Linux server. I tried in both Ubuntu and Red Hat. Independing of what uri I try to reach, it always raises me this exception: OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed from /usr/local/lib/ruby/1.8/net/http.rb:586:in `connect' from /usr/local/lib/ruby/1.8/net/http.rb:586:in `connect' from /usr/local/lib/ruby/1.8/net/http.rb:553:in `do_start' from /usr/local/lib/ruby/1.8/net/http.rb:542:in `start' from (irb):7 I think this have something to do with my installed OpenSSL package, but I can't be sure. This are my installed OpenSSL packages: openssl.x86_64 0.9.8e-12.el5 installed openssl-devel.x86_64 0.9.8e-12.el5 installed I tried using HTTParty as well, but it just ignores the SSL certificated. I hope someone can help me, either by telling me a gem that works the way I need. Thanks.

  • Common practice for higher-order-polymorphism in scala

    - by raichoo
    Hi, I'm trying to grasp higher-order-polymophism in scala by implementing a very basic interface that describes a monad but I come across a problem that I don't really understand. I implemented the same with C++ and the code looks like this: #include <iostream> template <typename T> class Value { private: T value; public: Value(const T& t) { this->value = t; } T get() { return this->value; } }; template < template <typename> class Container > class Monad { public: template <typename A> Container<A> pure(const A& a); }; template <template <typename> class Container> template <typename A> Container<A> Monad<Container>::pure(const A& a) { return Container<A>(a); } int main() { Monad<Value> m; std::cout << m.pure(1).get() << std::endl; return 0; } When trying to do the same with scala I fail: class Value[T](val value: T) class Monad[Container[T]] { def pure[A](a: A): Container[A] = Container[A](a) } object Main { def main(args: Array[String]): Unit = { val m = new Monad[Value] m.pure(1) } } The compiler complains about: [raichoo@lain:Scala]:434> scalac highorder.scala highorder.scala:5: error: not found: value Container Container[A](a) ^ one error found What am I doing wrong here? There seems to be a fundamental concept I don't seem to understand about scala typeconstructors. Regards, raichoo

  • Visual Studio 2008: Can't connect to known good TFS 2010 beta 2

    - by p.campbell
    A freshly installed TFS 2010 Beta 2 is at http://serverX:8080/tfs. A Windows 7 developer machine with VS 2008 Pro SP1 and the VS2008 Team Explorer (no SP). The TFS 2008 Service Pack 1 didn't work for me - "None of the products that are addressed by this software update are installed on this computer." The developer machine is able to browse the TFS site at the above URL. The Issue is around trying to add the TFS server into the Team Explorer window in Visual Studio 2008. Here's a screenshot showing the error: unable to connect to this Team Foundation Server. Possible reasons for failure include: The Team Foundation Server name, port number or protocol is incorrect. The Team Foundation Server is offline. Password is expired or incorrect. The TFS server is up and running properly. Firewall ports are open, and is accessible via the browser on the dev machine!! larger image Question: how can you connect from VS 2008 Pro to a TFS 2010 Beta 2 server? Resolution Here's how I solved this problem: installed VS 2008 Team Explorer as above. re-install VS 2008 Service Pack 1 when adding a TFS server to Team Explorer, you MUST specify the URL as such: http://[tfsserver]:[port]/[vdir]/[projectCollection] in my case above, it was http://serverX:8080/tfs/AppDev-TestProject you cannot simply add the TFS server name and have VS look for all Project Collections on the server. TFS 2010 has a new URL (by default) and VS 2008 doesn't recognize how to gather that list.

  • How To Get the Name of the Current Procedure/Function in Delphi (As a String)

    - by Andreas Rejbrand
    Is it possible to obtain the name of the current procedure/function as a string, within a procedure/function? I suppose there would be some "macro" that is expanded at compile-time. My scenario is this: I have a lot of procedures that are given a record and they all need to start by checking the validity of the record, and so they pass the record to a "validator procedure". The validator procedure raises an exception if the record is invalid, and I want the message of the exception to include not the name of the validator procedure, but the name of the function/procedure that called the validator procedure (naturally). That is, I have procedure ValidateStruct(const Struct: TMyStruct; const Sender: string); begin if <StructIsInvalid> then raise Exception.Create(Sender + ': Structure is invalid.'); end; and then procedure SomeProc1(const Struct: TMyStruct); begin ValidateStruct(Struct, 'SomeProc1'); ... end; ... procedure SomeProcN(const Struct: TMyStruct); begin ValidateStruct(Struct, 'SomeProcN'); ... end; It would be somewhat less error-prone if I instead could write something like procedure SomeProc1(const Struct: TMyStruct); begin ValidateStruct(Struct, {$PROCNAME}); ... end; ... procedure SomeProcN(const Struct: TMyStruct); begin ValidateStruct(Struct, {$PROCNAME}); ... end; and then each time the compiler encounters a {$PROCNAME}, it simply replaces the "macro" with the name of the current function/procedure as a string literal.
