• Push TFS 2008 code to remote VSS over VPN?

  - by drovani

  We have a local Team Foundation Server 2008 that we keep our code under version control. However, we also have a paranoid client that has their own Visual Source Safe installation that wants us to keep a running copy of the code on their server as well. As such, I'm hoping there is a way I can just do a nightly push from our TFS repository to their VSS repository. I'm not concerned about keeping each changeset on TFS as a different changeset on the VSS, just a once-nightly push that creates a new changeset on the VSS and uploads the latest changeset from TFS. I guess the first part is if it is even possible for TFS to push an update to VSS. I've noticed that most replies to this question have been something to the tune of "don't do it", but I can't find anything that specifically states that it cannot be done. The second part would then be automating the process by having the TFS server connect to the client's VPN, then push the code changes. I have full control over the TFS server and I can customize the VSS install, if there are settings that need changing, but I'm limited on what I can do about settings on either firewall or server specific settings on the client's VSS server.

• navigate all items in a wpf tree view

  - by Brian Leahy

  I want to be able to traverse the visual ui tree looking for an element with an ID bound to the visual element's Tag property. I'm wondering how i do this. Controls don't have children to traverse. I started using LogicalTreeHelper.GetChildren, which seems to work as intended, up until i hit a TreeView control... then LogicalTreeHelper.GetChildren doesnt return any children. Note: the purpose is to find the visual UI element that corresponds to the data item. That is, given an ID of the item, Go find the UI element displaying it. Edit: I am apparently am not explaining this well enough. I am binding some data objects to a TreeView control and then wanting to select a specific item programaticly given that business object's ID. I dont see why it's so hard to travers the visual tree and find the element i want, as the data object's ID is in the Tag property of the appropriate visual element. I'm using Mole and I am able to find the UI element with the appropriate ID in it's Tag. I just cannot find the visual element in code. LogicalTreeHelper does not traverse any items in the tree. Neither does ItemContainerGenerator.ContainerFromItem retrieve anything for items in the tree view.

• jCarousel - achieving an active state AND wrap:circular

  - by swisstony

  Hey folks A while back I implemented the jCarousel image solution for a client that required a numbered active state. After a bit of googling a found the answer but noticed that the preferred circular option would not work. What would happen is that once the carousel had cycled through all its (5) images, upon the return to the first, the active state would be lost, because, according to jcarousel it was actually the 6th (the index just keeps on incrementing). I just went ahead and instead used wrap:'both' which at least had a correctly functioning active state. However now the client says they dont like this effect and simply want the animation to return to position 1 after the final image. This means I need to get'wrap: 'both' working somehow. Below is my current code. Can someone please solve this one, as its a little above my head! function highlight(carousel, obejctli,liindex,listate){ jQuery('.jcarousel-control a:nth-child('+ liindex +')').attr("class","active"); }; function removehighlight(carousel, obejctli,liindex,listate){ jQuery('.jcarousel-control a:nth-child('+ liindex +')').removeAttr("class","active"); }; jQuery('#mycarousel').jcarousel({ initCallback: mycarousel_initCallback, auto: 5, wrap: 'both', vertical: true, scroll: 1, buttonNextHTML: null, buttonPrevHTML: null, animation: 1000, itemVisibleInCallback: highlight, itemVisibleOutCallback: removehighlight }); }); Thanks in advance

• real time stock quotes, StreamReader performance optimization

  - by sean717

  I am working on a program that extracts real time quote for 900+ stocks from a website. I use HttpWebRequest to send HTTP request to the site and store the response to a stream and open a stream using the following code: HttpWebResponse response = (HttpWebResponse)request.GetResponse(); Stream stream = response.GetResponseStream (); StreamReader reader = new StreamReader( stream ) the size of the received HTML is large (5000+ lines), so it takes a long time to parse it and extract the price. For 900 files, It takes about 6 mins for parsing and extracting. Which my boss isn't happy with, he told me he'd want the whole process to be done in TWO mins. I've identified the part of the program that takes most of time to finish is parsing and extracting. I've tried to optimize the code to make it faster, the following is what I have now after some optimization: // skip lines at the top for(int i=0;i<1500;++i) reader.ReadLine(); // read the line that contains the price string theLine = reader.ReadLine(); // ... extract the price from the line now it takes about 4 mins to process all the files, there is still a significant gap to what my boss's expecting. So I am wondering, is there other way that I can further speed up the parsing and extracting and have everything done within 2 mins?

• Sync two SqlExpress using NHibernate

  - by Christian

  Hello, I am creating a simple project management system which uses NHibernate for object storage. The underlying database is SQL express (at least currently for development). The client runs on either the desktop or laptop. I know I could use web-services and store the DB only on the desktop, but this would force the desktop to be available all the time. I am currently thinking about duplicating the DB, having two instances with "different data". To clarify, we are not talking about a productive app here, its a prototype. One way to achieve this very simple would be the following process: Client: Check if desktop DB is available (through web service) Client: If yes, use desktop storage, no problem here Client: If not, use own DB as storage Client: Poll desktop regulary, as soon as it comes on, sync Client: Switch to desktop storage ... Desktop: Do not attempt any DB operation before checking for required sync Desktop: If sync needed, do it... My question is now, how would you sync? Assume 4 or 5 types of objects, all have GUID as identifiers. Would you always manually "lazy load" all objects of a certain type and feed them to the DB. Would you always drop the whole desktop DB in case the client DB may be newer and out of sync? Again, I want to stress out, I am not assuming any conflicts or stale data, I basically just want to "copy the whole DB from the client". Would you use NHibernate for this? Or would you separate the copy process? When I think about it, my questions comes down to this: Is there any function from NHibernate: SyncDBs_SourceWins_(SourceDB, TargetDB) Thanks for help, Chris

• Impersonate SYSTEM (or equivalent) from Administrator Account

  - by KevenK

  This question is a follow up and continuation of this question about a Privilege problem I'm dealing with currently. Problem Summary: I'm running a program under a Domain Administrator account that does not have Debug programs (SeDebugPrivilege) privilege, but I need it on the local machine. Klugey Solution: The program can install itself as a service on the local machine, and start the service. Said service now runs under the SYSTEM account, which enables us to use our SeTCBPrivilege privilege to create a new access token which does have SeDebugPrivilege. We can then use the newly created token to re-launch the initial program with the elevated rights. I personally do not like this solution. I feel it should be possible to acquire the necessary privileges as an Administrator without having to make system modifications such as installing a service (even if it is only temporary). I am hoping that there is a solution that minimizes system modifications and can preferably be done on the fly (ie: Not require restarting itself). I have unsuccessfully tried to LogonUser as SYSTEM and tried to OpenProcessToken on a known SYSTEM process (such as csrss.exe) (which fails, because you cannot OpenProcess with PROCESS_TOKEN_QUERY to get a handle to the process without the privileges I'm trying to acquire). I'm just at my wit's end trying to come up with an alternative solution to this problem. I was hoping there was an easy way to grab a privileged token on the host machine and impersonate it for this program, but I haven't found a way. If anyone knows of a way around this, or even has suggestions on things that might work, please let me know. I really appreciate the help, thanks!

• DotNetNuke and Subversion guidelines

  - by David Stratton

  I've Googled, Binged, and here at StackOverflow, looked through the related questions and searched, but I'm not finding what I'm looking for. I've also searched documentation on DNN. What I'm looking for is any guidance (tutorials, blogs, step-by-step instructions for setting up a repository) etc from people who are experienced in using DotNetNuke with SVN. We use SVN for all our source control, and have no problem with standard applications, because we pretty much built the repository and directory structure to work with our processes. This means when we do web sites, in Visual Studio, we do file based web sites, rather than setting them up in the local IIS. It just makes things easier for us. However, with DNN, it appears that even if you get the source code, it is expecting to be set up in the local IIS, which means additional headaches for us. For example, we are moving all of our source code off our local C drives, and onto a shared drive on a server. This is to enable backups in addition to our normal source control. (This was a management decision). So that means that we need to change the virtual web app when we make the move. Has anyone come up with a good way to work around this? Can DNN be set up so that the developer web server in Visual Studio can be used, so that we can treat it just like any normal web app? Am I missing something obvious? Edit - added I'm willing to accept answers like "We tried it and never got it to work", and "It can't be done" as answers. I'm always open to hearing "It can't be done the way you want. You need to change your procedures to match how it works" if necessary. I guess if you've got experience trying this and just couldn't get it to work, I can learn from your experience that way as well, but some detail would be good.

• Can I get debug symbols for flash player? Or any other way to get support for flash?

  - by Tim

  The company I am working for has a flash component (using flex and cs4) that crashes intermittently in chrome, FF and IE. (so far only win32 platforms) I submitted a bug report to Adobe but have not heard anything back from them. Their support process seems like a black hole. WE can get a dump from Flash using these steps but after submitting the bug we got no help at all. We loaded this into MS visual studio but can;t get decent stack information because there are no symbols for the flash stuff. Microsoft and other companies provide symbols to help with debugging and we would like to get that from adobe. Is there any way to make progress on this? Does anyone know where to get flash symbols or how else we can make progress? It is hard to debug the process if the container just dies. the binary is flash10c.ocx I just spent a painful hour on the phone with adobe folks - and the final answer from one of them (I spoke to about 8 people) was that they do not have a per incident purchase plan for developer support for flash. I find that hard to believe. Does anyone know how to get support for Flash?

• Low Level Console Input

  - by Soulseekah

  I'm trying to send commands to to the input of a cmd.exe application using the low level read/write console functions. I have no trouble reading the text (scraping) using the ReadConsole...() and WriteConsole() functions after having attached to the process console, but I've not figured out how to write for example "dir" and have the console interpret it as a sent command. Here's a bit of my code: CreateProcess(NULL, "cmd.exe", NULL, NULL, FALSE, CREATE_NEW_CONSOLE, NULL, NULL, &si, &pi); AttachConsole(pi.dwProcessId); strcpy(buffer, "dir"); WriteConsole(GetStdHandle(STD_INPUT_HANDLE), buffer, strlen(buffer), &charRead, NULL); STARTUPINFO attributes of the process are all set to zero, except, of course, the .cb attribute. Nothing changes on the screen, however I'm getting an Error 6: Invalid Handle returned from WriteConsole to STD_INPUT_HANDLE. If I write to (STD_OUTPUT_HANDLE) I do get my dir written on the screen, but nothing of course happens. I'm guessing SetConsoleMode() might be of help, but I've tried many mode combinations, nothing helped. I've also created a quick console application that waits for input (scanf()) and echoes back whatever goes in, didn't work. I've also tried typing into the scanf() promp and then peek into the input buffer using PeekConsoleInput(), returns 0, but the INPUT_RECORD array is empty. I'm aware that there is another way around this using WriteConsoleInput() to directly inject INPUT_RECORD structured events into the console, but this would be way too long, I'll have to send each keypress into it. I hope the question is clear. Please let me know if you need any further information. Thanks for your help.

• C++. How to define template parameter of type T for class A when class T needs a type A template parameter?

  - by jaybny

  Executor class has template of type P and it takes a P object in constructor. Algo class has a template E and also has a static variable of type E. Processor class has template T and a collection of Ts. Question how can I define Executor< Processor<Algo> > and Algo<Executor> ? Is this possible? I see no way to defining this, its kind of an "infinite recursive template argument" See code. template <class T> class Processor { map<string,T> ts; void Process(string str, int i) { ts[str].Do(i); } } template <class P> class Executor { Proc &p; Executor(P &p) : Proc(p) {} void Foo(string str, int i) { p.Process(str,i); } Execute(string str) { } } template <class E> class Algo { static E e; void Do(int i) {} void Foo() { e.Execute("xxx"); } } main () { typedef Processor<Algo> PALGO; // invalid typedef Executor<PALGO> EPALGO; typedef Algo<EPALGO> AEPALGO; Executor<PALGO> executor(PALGO()); AEPALGO::E = executor; }

• Disposing ActiveX resources owned by another thread

  - by Stefan Teitge

  I've got a problem problem with threading and disposing resources. I've got a C# Windows Forms application which runs expensive operation in a thread. This thread instantiates an ActiveX control (AxControl). This control must be disposed as it uses a high amount of memory. So I implemented a Dispose() method and even a destructor. After the thread ends the destructor is called. This is sadly called by the UI thread. So invoking activexControl.Dispose(); fails with the message "COM object that has been separated from its underlying RCW", as the object belongs to another thread. How to do this correctly or is it just a bad design I use? (I stripped the code down to the minimum including removing any safety concerns.) class Program { [STAThread] static void Main() { // do stuff here, e.g. open a form new Thread(new ThreadStart(RunStuff); // do more stuff } private void RunStuff() { DoStuff stuff = new DoStuff(); stuff.PerformStuff(); } } class DoStuff : IDisposable { private AxControl activexControl; DoStuff() { activexControl = new AxControl(); activexControl.CreateControl(); // force instance } ~DoStuff() { Dispose(); } public void Dispose() { activexControl.Dispose(); } public void PerformStuff() { // invent perpetuum mobile here, takes time } }

• how to create static line in coreplot

  - by Rémi Bédard-Couture

  I am trying to make my control lines static so instead of being displayed as part of the graph(the control lines are moving with the graph), they would be displayed like an axis the app can only scroll horizontally i'm talking about the two red line and the green line(which i put over the x axis) this is how i do my lines: // Center line CPTScatterPlot *centerLinePlot = [[CPTScatterPlot alloc] init]; centerLinePlot.identifier = kCenterLine; CPTMutableLineStyle *lineStyle = [CPTMutableLineStyle lineStyle]; lineStyle.lineWidth = 2.0; lineStyle.lineColor = [CPTColor greenColor]; centerLinePlot.dataLineStyle = lineStyle; centerLinePlot.dataSource = self; [graph addPlot:centerLinePlot]; but maybe it has something to do with the displayed range: ////////ajuste la portion a voir if(data.Resultats.count>10) { plotSpace.xRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromDouble(data.Resultats.count - 10) length:CPTDecimalFromDouble(10)]; } plotSpace.yRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromDouble(RangeMin) length:CPTDecimalFromDouble(RangeMax-RangeMin)]; // Adjust visible ranges so plot symbols along the edges are not clipped CPTMutablePlotRange *xRange = [plotSpace.xRange mutableCopy]; CPTMutablePlotRange *yRange = [plotSpace.yRange mutableCopy]; //place l'axe x sur la ligne de controle pour voir les WorkOrders x.orthogonalCoordinateDecimal = CPTDecimalFromDouble(center); //x.orthogonalCoordinateDecimal = yRange.location; //y.orthogonalCoordinateDecimal = xRange.location; //x.visibleRange = xRange; //y.visibleRange = yRange; //x.gridLinesRange = yRange; //y.gridLinesRange = xRange; [xRange expandRangeByFactor:CPTDecimalFromDouble(1.15)];//1.05 [yRange expandRangeByFactor:CPTDecimalFromDouble(1.15)]; plotSpace.xRange = xRange; plotSpace.yRange = yRange;

• Which pdf elements could cause crashes?

  - by Felixyz

  This is a very general question but it's based on a specific problem. I've created a pdf reader app for the iPad and it works fine except for certain pdf pages which always crash the app. We now found out that the very same pages cause Safari to crash as well, so as I had started to suspect the problem is somewhere in Apple's pdf rendering code. From what I have been able to see, the crashing pages cause the rendering libraries to start allocating memory like mad until the app is killed. I have nothing else to help me pinpoint what triggers this process. It doesn't necessarily happen with the largest documents, or the ones with the most shapes. In fact, we haven't found any parameter that helps us predict which pages will crash and which not. Now we just discovered that running the pages through a consumer program that lets you merge docs gets rid of the problem, but I haven't been able to detect which attribute or element it is that is the key. Changing documents by hand is also not an option for us in the long run. We need to run an automated process on our server. I'm hoping someone with deeper knowledge about the pdf file format would be able to point me in a reasonable direction to look for document features that could cause this kind of behavior. All I've found so far is something about JBIG2 images, and I don't think we have any of those.

• How to best launch C++ application from web page

  - by JB

  I guess there are two parts to this question, one technical and one best practice for security and doing things "right". I'm working on a little game using C++ / directx but I would like to be able to launch it from a web page by someone clicking on a link on that page. Ideally I would like the first time they clicked for it to launch an installer downloads and installs the game on their machine, and then the next time to launch an application which updates the game from a web site if it's old and then launches it. I have no problems with the expected security popups and questions the first time it runs. I want people to be certain what they are installing and understand what they are doing. But it would be nice if once it is installed they could run it with the minimum of fuss. My question then is what technologies I could use to do this? I'm thinking that it would need a browser plugin and an activex control so that first time you'd install that, and subsequently the control/plugin would be able to launch the game. I'm not sure that under newer browser secuity models that a plugin would have the permissions to be able to run an installer though or silently invoke applications on the client machine even if they are already installed. Is there a more sensible way to achive what I want to achieve? And I'm worried about the security aspects too. I want this to be convenient for users but I of course want to do it "right". I know this can be done as I've seen several mmorpg type games that launch in this way from the browser now but it's not entirely clear to me how they've done it.

• Windows loader problem - turn on verbose mode

  - by doobop

  Hi, I'm in the process of reorganizing some of the legacy libraries in our application which has unmanaged code calling into libraries of managed code. While I have the code reorganized, it produces the following loader error: ... 'app.exe': Loaded 'C:\WINDOWS\system32\CsDisp.dll' 'app.exe': Loaded 'C:\WINDOWS\system32\psapi.dll' 'app.exe': Loaded 'C:\WINDOWS\system32\shell32.dll' 'app.exe': Loaded 'C:\appCode\Debug\daq206_32.dll', Binary was not built with debug information. 'app.exe': Loaded 'C:\appCode\Debug\SiUSBXp.dll', Binary was not built with debug information. 'app.exe': Loaded 'C:\appCode\Debug\AdlinkDAQ.dll', Symbols loaded. 'app.exe': Loaded 'C:\WINDOWS\system32\P9842.dll', Binary was not built with debug information.

So, I have two questions. First, what linker options may cause this error? I'm currently linking with /DYNAMICBASE:NO and /FIXED:No as this was how some of the previous libraries were set up. Second, is there a way to turn on verbose mode for the loader so I can see what exactly it's trying to load? P9842 is a third party library so I imagine it is getting to one of my libraries after P9842 and failing on that one. Can I narrow it down? Thanks.

• How to delete duplicate/aggregate rows faster in a file using Java (no DB)

  - by S. Singh

  I have a 2GB big text file, it has 5 columns delimited by tab. A row will be called duplicate only if 4 out of 5 columns matches. Right now, I am doing dduping by first loading each coloumn in separate List , then iterating through lists, deleting the duplicate rows as it encountered and aggregating. The problem: it is taking more than 20 hours to process one file. I have 25 such files to process. Can anyone please share their experience, how they would go about doing such dduping? This dduping will be a throw away code. So, I was looking for some quick/dirty solution, to get job done as soon as possible. Here is my pseudo code (roughly) Iterate over the rows i=current_row_no. Iterate over the row no. i+1 to last_row if(col1 matches //find duplicate && col2 matches && col3 matches && col4 matches) { col5List.set(i,get col5); //aggregate } Duplicate example A and B will be duplicate A=(1,1,1,1,1), B=(1,1,1,1,2), C=(2,1,1,1,1) and output would be A=(1,1,1,1,1+2) C=(2,1,1,1,1) [notice that B has been kicked out]

• jQuery > Update inline script on form submission

  - by Andrew Kirk

  I am using the ChemDoodle Web Components to display molecules on a web page. Basically, I can just insert the following script in my page and it will create an HTML5 canvas element to display the molecule. <script> var transform1 = new TransformCanvas('transform1', 200, 200, true); transform1.specs.bonds_useJMOLColors = true; transform1.specs.bonds_width_2D = 3; transform1.specs.atoms_useJMOLColors = true; transform1.specs.atoms_circles_2D = true; transform1.specs.backgroundColor = 'black'; transform1.specs.bonds_clearOverlaps_2D = true; transform1.loadMolecule(readPDB(molecule)); </script> In this example, "molecule" is a variable that I have defined in an external script by using the jQuery.ajax() function to load a PDB file. This is all fine and good. Now, I would like to include a form on the page that will allow a user to paste in a PDB molecule definition. Upon submitting the form, I want to update the "molecule" variable with the form data so that the ChemDoodle Web Components script will work its magic and display molecule defined by the PDB definition pasted into the form. I am using the following jQuery code to process the the form submission. $(".button").click(function() { // validate and process form here //hide previous errors $('.error').hide(); //validate pdb textarea field var pdb = $("textarea#pdb").val(); if (pdb == "") { $("label#pdb_error").show(); $("textarea#pdb").focus(); return false; } molecule = pdb; }); This code is setting the "molecule" variable upon the form submission but it is not being passed back to the inline script as I had hoped. I have tried a number of variations on this but can't seem to get it right. Any clues as to where I might be going wrong would be much appreciated.

• Safari specific scroll bar issue in legacy code

  - by user1237169

  I am trying to debug an issue that is occurring specifically in Safari. On a few pages of a web application, the content is larger than the frame and a scroll bar appears on the right but when the scroll bar moves up or down the content does not scroll with it. So you can "scroll" the scroll bar but the content itself was inaccessible even though the scroll bar was mobile. The issue only occurs in the "Multi-Process Windows" debug mode option but not in the "Single-Process Windows" option. The scroll bar works perfectly fine in Firefox, IE, and Chrome, just not in Safari. Because there's a lot of legacy code, I'm not quite sure exactly what the actual content is and which specific html elements are relevant. From what I can tell there's an Iframe element, html element, body element, div element, iframe element html element, body element and finally some divs. edit Does it matter if some of the elements within the <iframe> have the attribute scrolling="no"? I see this on a few of the elements within iframe but my coworker reassures me they don't matter.

• The same C# code produces different output in Visio Professional and Premium

  - by user615993

  I have built a simple conversion Add In, but its behavior is unfortunately different with the different Visio Editions (Visio 2010 Professional and Visio 2010 Premium). The Add In takes a Process-Diagram created with Shapes from Stencil_1.vss and creates a new slightly different Process-Diagram with Shapes from Stencil_2.vsd. It loops through a Visio page and for each shape founded creates a new shapes from new master shape (from Stencil_2.vsd) and drop it into the new page. Geometry, captions etc. are the same, only the shape-appearance is changed. Below is the source diagram: When I run the code into Visio 2010 Professional the swimlane shapes are drawn correctly. When I run the same code from Visio Premium the swimlane appearance and layout are mismatched: Both times i drop the SAME Shape("Swimlane" from the same stencil) into the Page with the SAME Code fragment: Visio.Master vm = swimlane_stencil.Masters.get_ItemU(@"Swimlane"); Visio.Shape TargetShape = targetPage.Drop(vm, shape_x, shape_y); How could I ensure, that the code produces any time the same (correct) output? Must I disable any (premium)features in the swimlane-shapesheet?

• Capture and handling the tab/Textchanged event in a textbox in asp.net MVC

Here is the user control which has a user name textbox: <%: Html.TextBox("UserName", Model.Username, new { maxlength = "40", size = "20", tabindex = "1", @onchange = "CheckAvailability()" })% CheckAvailability() is defined in the User.Validation.js and included in the above user control: $(document).ready(function () { function CheckAvailability() { $.post("/Home/Survey/CheckAvailability", { Username: $("#UserName").val() }, function (data) { var myObject = eval('(' + data + ')'); var newid = myObject; if (newid == 0) { $("#usernamelookupresult").html("<font color='green'>Available :-D</font>") } else { $("#usernamelookupresult").html("<font color='red'>Taken :-(</font>") } }); } }); Here is the survey controller function which will have server side validation: [HttpPost] public ActionResult CheckAvailability(string Username) { int Taken = 0; // This is where you add your database lookup if (Username == "abc") { Taken = 1; } return Json(Taken); }

• Windows Services in Win7?

  - by Brandi

  I am trying to make a service that spawns a desktop application, and then watches to make sure it restarts again if it is closed. . I would like it to basically spawn the process and then forget about it, allowing to act like a normal interactive application. (Apparently this is much easier to do in XP and before, but I need this for XP, Vista, and 7) My problem now is that either it shows up invisible if I use process.start() with desktop interactive checked, and if I directly spawn a form it asks "Do you REALLY want to do this?!" and then the whole screen goes blank EXCEPT for my program. I just want this to be an inoffensive background app. I have the app working well, I just need to figure out how to spawn it from a service without all the trouble. I am finding all of this stuff that says "Don't make services that have UI", but first off this was a requirement that was given to me. (Boss does not want it to be a scheduled task) Also, I noticed that the Task scheduler is itself a service, and it does not have any problem spawning user interactive applications. Why can't I do that too? What am I doing wrong?

• Problems finding classes in namespace and testing extend expected parent

  - by Matt

  So I am in the process of building a site in ASP.Net MVC, and in the process I am adding certain things to my Site.Master I want to make sure that all of my model classes extend a certain base class that contains all of the pieces the Site.Master needs to be operable. I want to test to make sure this assumption isn't broken (I believe this will save me time when I forget about it and can't figure out why a new combination isn't working.) I wrote a test that I thought would help with this, but I am running into two problems. First it isn't finding the one example model class I have so far in the LINQ call all of a sudden, I am admittedly still a bit new to LINQ. Second, I had it finding the class earlier, but I couldn't get it to verify that the class inherits from the base class. Here is the example test. [Test] public void AllModelClassesExtendAbstractViewModel() { var abstractViewModelType = typeof (AbstractViewModel); Assembly baseAssembly = Assembly.GetAssembly(abstractViewModelType); var modelTypes = baseAssembly.GetTypes() .Where(assemblyType => (assemblyType.Namespace.EndsWith("Models") && assemblyType.Name != "AbstractViewModel")) .Select(assemblyType => assemblyType); foreach (var modelType in modelTypes) { Assert.That(modelType.IsSubclassOf(abstractViewModelType), Is.True , modelType.Name + " does not extend AbstractViewModel"); } }

• .NET ValidationRule problem

  - by PaN1C_Showt1Me

  Hi ! I have a control with this validation <MyPicker.SelectedItem> <Binding Path="Person.Value" Mode="TwoWay" UpdateSourceTrigger="PropertyChanged" NotifyOnValidationError="True"> <Binding.ValidationRules> <rules:MyValidationRule ValidationType="notnull"/> </Binding.ValidationRules> </Binding> </MyPicker.SelectedItem> This is the Validation Class: class MyValidationRule : ValidationRule { private string _validationType; public string ValidationType { get { return _validationType; } set { _validationType = value; } } public override ValidationResult Validate(object value, CultureInfo cultureInfo) { ValidationResult trueResult = new ValidationResult(true, null); switch (_validationType.ToLower()) { case "notnull": return value == null ? new ValidationResult(false, "EMPTY FIELD") : trueResult; default: return trueResult; } } } Question: When the property is changed, then the Validate( ) method is called which is correct. But to call this method at the very beginning when the MyControl is created? I need to prove immediate after initialize if the there's a null value in the control (and display a validation error)

• Tips for Using Multiple Development Systems

  - by Tim Lytle

  When I travel, I don't pack up the desktop I use in the office and take it with me. Maybe I should, but I don't. However, since I'm a contract programmer I like to be able to work wherever I am: I'm mostly thinking of web development here. Version Control goes a long way in keeping sane and working on multiple projects on multiple systems (two or three computers); however, there are the issues of: IDE settings - different display sizes mean the IDE settings can't be completely synced, if at all. Database - if the database is 'external' (even if it's running on the same system, it's not in version control), how do you maintain the needed syncs of structure. Development Stack - Some projects need non-standard extensions, libraries, etc installed. Just an overview of some of the hassle involved with developing on multiple systems. I'll probably end up asking some specific questions, but I thought a CW style tips might reveal some things I would even think to ask about. Update: I guess this would also address tips to make upgrading/replacing your development system easier (something I've just done). So, one tip per answer please, so the 'top' tips are easy to find. How do you make it easier to develop on multiple systems, or to transfer work after upgrading/replaceing a development system?
