• Same source, multiple targets with different resources (Visual Studio .Net 2008)

  - by Mike Bell

  A set of software products differ only by their resource strings, binary resources, and by the strings / graphics / product keys used by their Visual Studio Setup projects. What is the best way to create, organize, and maintain them? i.e. All the products essentially consist of the same core functionality customized by graphics, strings, and other resource data to form each product. Imagine you are creating a set of products like "Excel for Bankers", Excel for Gardeners", "Excel for CEOs", etc. Each product has the the same functionality, but differs in name, graphics, help files, included templates etc. The environment in which these are being built is: vanilla Windows.Forms / Visual Studio 2008 / C# / .Net. The ideal solution would be easy to maintain. e.g. If I introduce a new string / new resource projects I haven't added the resource to should fail at compile time, not run time. (And subsequent localization of the products should also be feasible). Hopefully I've missed the blindingly-obvious and easy way of doing all this. What is it? ============ Clarification(s) ================ By "product" I mean the package of software that gets installed by the installer and sold to the end user. Currently I have one solution, consisting of multiple projects, (including a Setup project), which builds a set of assemblies and create a single installer. What I need to produce are multiple products/installers, all with similar functionality, which are built from the same set of assemblies but differ in the set of resources used by one of the assemblies. What's the best way of doing this? ------------ The 95% Solution ----------------- Based upon Daminen_the_unbeliever's answer, a resource file per configuration can be achieved as follows: Create a class library project ("Satellite"). Delete the default .cs file and add a folder ("Default") Create a resource file in the folder "MyResources" Properties - set CustomToolNamespace to something appropriate (e.g. "XXX") Make sure the access modifier for the resources is "Public". Add the resources. Edit the source code. Refer to the resources in your code as XXX.MyResources.ResourceName) Create Configurations for each product variant ("ConfigN") For each product variant, create a folder ("VariantN") Copy and Paste the MyResources file into each VariantN folder Unload the "Satellite" project, and edit the .csproj file For each "VariantN/MyResources" <Compile> or <EmbeddedResource> tag, add a Condition="'$(Configuration)' == 'ConfigN'" attribute. Save, Reload the .csproj, and you're done... This creates a per-configuration resource file, which can (presumably) be further localized. Compile error messages are produced for any configuration that where a a resource is missing. The resource files can be localized using the standard method (create a second resources file (MyResources.fr.resx) and edit .csproj as before). The reason this is a 95% solution is that resources used to initialize forms (e.g. Form Titles, button texts) can't be easily handled in the same manner - the easiest approach seems to be to overwrite these with values from the satellite assembly.

• Templates, interfaces (multiple inheritance) and static functions (named constructors)

  - by fledgling Cxx user

  Setup I have a graph library where I am trying to decompose things as much as possible, and the cleanest way to describe it that I found is the following: there is a vanilla type node implementing only a list of edges: class node { public: int* edges; int edge_count; }; Then, I would like to be able to add interfaces to this whole mix, like so: template <class T> class node_weight { public: T weight; }; template <class T> class node_position { public: T x; T y; }; and so on. Then, the actual graph class comes in, which is templated on the actual type of node: template <class node_T> class graph { protected: node_T* nodes; public: static graph cartesian(int n, int m) { graph r; r.nodes = new node_T[n * m]; return r; } }; The twist is that it has named constructors which construct some special graphs, like a Cartesian lattice. In this case, I would like to be able to add some extra information into the graph, depending on what interfaces are implemented by node_T. What would be the best way to accomplish this? Possible solution I thought of the following humble solution, through dynamic_cast<>: template <class node_T, class weight_T, class position_T> class graph { protected: node_T* nodes; public: static graph cartesian(int n, int m) { graph r; r.nodes = new node_T[n * m]; if (dynamic_cast<node_weight<weight_T>>(r.nodes[0]) != nullptr) { // do stuff knowing you can add weights } if (dynamic_cast<node_position<positionT>>(r.nodes[0]) != nullptr) { // do stuff knowing you can set position } return r; } }; which would operate on node_T being the following: template <class weight_T, class position_T> class node_weight_position : public node, public node_weight<weight_T>, public node_position<position_T> { // ... }; Questions Is this -- philosophically -- the right way to go? I know people don't look nicely at multiple inheritance, though with "interfaces" like these it should all be fine. There are unfortunately problems with this. From what I know at least, dynamic_cast<> involves quite a bit of run-time overhead. Hence, I run into a problem with what I had solved earlier: writing graph algorithms that require weights independently of whether the actual node_T class has weights or not. The solution with this 'interface' approach would be to write a function: template <class node_T, class weight_T> inline weight_T get_weight(node_T const & n) { if (dynamic_cast<node_weight<weight_T>>(n) != nullptr) { return dynamic_cast<node_weight<weight_T>>(n).weight; } return T(1); } but the issue with it is that it works using run-time information (dynamic_cast), yet in principle I would like to decide it at compile-time and thus make the code more efficient. If there is a different solution that would solve both problems, especially a cleaner and better one than what I have, I would love to hear about it!

• Starting out Silverlight 4 design

  - by Fermin

  I come from mainly a web development background (ASP.NET, ASP.NET MVC, XHTML, CSS etc) but have been tasked with creating/designing a Silverlight application. The application is utilising Bing Maps control for Silverlight, this will be contained in a user control and will be the 'main' screen in the system. There will be numerous other user controls on the form that will be used to choose/filter/sort/order the data on the map. I think of it like Visual Studio: the Bing Maps will be like the code editor window and the other controls will be like Solutions Explorer, Find Results etc. (although a lot less of them!) I have read up and I'm comfortable with the data side (RIA-Services) of the application. I've (kinda) got my head around databinding and using a view model to present data and keep the code behind file lite. What I do need some help on is UI design/navigation framework, specifically 2 aspects: How do I best implement a fluid design so that the various user controls which filter the map data can be resized/pinned/unpinned (for example, like the Solution Explorer in VS)? I made a test using a Grid with a GridSplitter control, is this the best way? Would it be best to create a Grid/Gridsplitter with Navigation Frames inside the grid to load the content? Since I have multiple user controls that basically use the same set of data, should I set the dataContext at the highest possible level (e.g. if using a grid with multiple frames, at the Grid level?). Any help, tips, links etc. will be very much appreciated!

• Visual Studio Macros on 64 bit fail with COM error

  - by bruce.kinchin

  I'm doing some javascript development and found a cool macro to region my code ("Using #region Directive With JavaScript Files in Visual Studio"). I used this on my 32 bit box, and it worked first time. (Visual Studio 2008 SP1, Win7) For easy of reference the macro is: Option Strict Off Option Explicit Off Imports System Imports EnvDTE Imports EnvDTE80 Imports System.Diagnostics Imports System.Collections Public Module JsMacros Sub OutlineRegions() Dim selection As EnvDTE.TextSelection = DTE.ActiveDocument.Selection Const REGION_START As String = "//#region" Const REGION_END As String = "//#endregion" DTE.ExecuteCommand("Edit.StopOutlining") selection.SelectAll() Dim text As String = selection.Text selection.StartOfDocument(True) Dim startIndex As Integer Dim endIndex As Integer Dim lastIndex As Integer = 0 Dim startRegions As Stack = New Stack() Do startIndex = text.IndexOf(REGION_START, lastIndex) endIndex = text.IndexOf(REGION_END, lastIndex) If startIndex = -1 AndAlso endIndex = -1 Then Exit Do End If If startIndex <> -1 AndAlso startIndex < endIndex Then startRegions.Push(startIndex) lastIndex = startIndex + 1 Else ' Outline region ... selection.MoveToLineAndOffset(CalcLineNumber(text, CInt(startRegions.Pop())), text.Length) selection.MoveToLineAndOffset(CalcLineNumber(text, endIndex) + 1, 1, True) selection.OutlineSection() lastIndex = endIndex + 1 End If Loop selection.StartOfDocument() End Sub Private Function CalcLineNumber(ByVal text As String, ByVal index As Integer) Dim lineNumber As Integer = 1 Dim i As Integer = 0 While i < index If text.Chars(i) = vbCr Then lineNumber += 1 i += 1 End If i += 1 End While Return lineNumber End Function End Module I then tried to use the same macro on two separate 64 bit machines (Win7 x64), identical other than the 64 bit OS version and it fails to work. Stepping through it with the Visual Studio Macros IDE, it fails the first time on the DTE.ExecuteCommand("Edit.StopOutlining") line with a COM error (Error HRESULT E_FAIL has been returned from a call to a COM component). If I attempt to run it a second time, I can run it from the Macro Editor with no issue, but not from within Visual Studio with the macro explorer 'run macro' command. I have reviewed the following articles without finding anything helpful: Stackoverflow: Visual Studio 2008 macro only works from the Macro IDE, not the Macro Explorer Recorded macro does not run; Failing on DTE.ExecuteCommand Am I missing something dumb?

• Maven2 - problem with pluginManagement and parent-child relationship

  - by Newtopian

  from maven documentation pluginManagement: is an element that is seen along side plugins. Plugin Management contains plugin elements in much the same way, except that rather than configuring plugin information for this particular project build, it is intended to configure project builds that inherit from this one. However, this only configures plugins that are actually referenced within the plugins element in the children. The children have every right to override pluginManagement definitions. Now : if I have this in my parent POM <build> <pluginManagement> <plugins> <plugin> <artifactId>maven-dependency-plugin</artifactId> <version>2.0</version> <executions> Some stuff for the children </execution> </executions> </plugin> </plugins> </pluginManagement> </build> and I run mvn help:effective-pom on the parent project I get what I want, namely the plugins part directly under build (the one doing the work) remains empty. Now if I do the following : <build> <pluginManagement> <plugins> <plugin> <artifactId>maven-dependency-plugin</artifactId> <version>2.0</version> <executions> Some stuff for the children </execution> </executions> </plugin> </plugins> </pluginManagement> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <version>2.0.2</version> <inherited>true</inherited> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> </plugins> </build> mvn help:effective-pom I get again just what I want, the plugins contains just what is declared and the pluginManagement section is ignored. BUT changing with the following <build> <pluginManagement> <plugins> <plugin> <artifactId>maven-dependency-plugin</artifactId> <version>2.0</version> <executions> Some stuff for the children </execution> </executions> </plugin> </plugins> </pluginManagement> <plugins> <plugin> <artifactId>maven-dependency-plugin</artifactId> <version>2.0</version> <inherited>false</inherited> <!-- this perticular config is NOT for kids... for parent only --> <executions> some stuff for adults only </execution> </executions> </plugin> </plugins> </build> and running mvn help:effective-pom the stuff from pluginManagement section is added on top of what is declared already. as such : <build> <pluginManagement> ... </pluginManagement> <plugins> <plugin> <artifactId>maven-dependency-plugin</artifactId> <version>2.0</version> <inherited>false</inherited> <!-- this perticular config is NOT for kids... for parent only --> <executions> Some stuff for the children </execution> <executions> some stuff for adults only </execution> </executions> </plugin> </plugins> </build> Is there a way to exclude the part for children from the parent pom's section ? In effect what I want is for the pluginManagement to behave exactly as the documentation states, that is I want it to apply for children only but not for the project in which it is declared. As a corrolary, is there a way I can override the parts from the pluginManagement by declaring the plugin in the normal build section of a project ? whatever I try I get that the section is added to executions but I cannot override one that exists already. EDIT: I never did find an acceptable solution for this and as such the issue remains open. Closest solution was offered below and is currently the accepted solution for this question until something better comes up. Right now there are three ways to achieve the desired result (modulate plugin behaviour depending on where in the inheritance hierarchy the current POM is): 1 - using profiles, it will work but you must beware that profiles are not inherited, which is somewhat counter intuitive. They are (if activated) applied to the POM where declared and then this generated POM is propagated down. As such the only way to activate the profile for child POM is specifically on the command line (least I did not find another way). Property, file and other means of activation fail to activate the POM because the trigger is not in the POM where the profile is declared. 2 - (this is what I ended up doing) Declare the plugin as not inherited in the parent and re-declare (copy-paste) the tidbit in every child where it is wanted. Not ideal but it is simple and it works. 3 - Split the aggregation nature and parent nature of the parent POM. Then since the part that only applies to the parent is in a different project it is now possible to use pluginManagement as firstly intended. However this means that a new artificial project must be created that does not contribute to the end product but only serves the could system. This is clear case of conceptual bleed. Also this only applies to my specific and is hard to generalize, so I abandoned efforts to try and make this work in favor of the not-pretty but more contained cut and paste patch described in 2. If anyone coming across this question has a better solution either because of my lack of knowledge of Maven or because the tool evolved to allow this please post the solution here for future reference. Thank you all for your help :-)

• What do I need to do to make a WPF Browser Application (XBAP) that requires Full Trust work on Windo

  - by Benoit J. Girard

  So this is a Visual Studio 2008, .NET, WPF, XBAP, Windows 7 question, regarding .NET trust policies. At work, we have several Web Browser Applications (.XBAP files) developed with Visual Studio 2008 (so .NET 3.5) that we deployed internally. These required a .NET FullTrust policy, we found a way to make a .MSI that adjusted the policy on individual stations, everything worked great. Users love in-browser apps. This was last year and on Windows XP. This year our company started upgrading users to Windows 7, and now none of our Web Browser Applications work. The error message is "Trust Not Granted", as if the policy-changing .MSI had not been run. Other details: I can confirm that our apps work on Windows XP for Internet Explorer 7 and Firefox, and do not work on Windows 7 for Internet Explorer 8 nor Firefox. I must admit that .NET security policies mystify me. Still, I could not find any mention of this problem on the Net at large or on this site. Did anybody else encounter this problem? Any and all help welcome.

• Shopify JSONP issue in ajaxAPI

  - by Aaron U

  I'm getting some odd response back from shopify ajaxapi for jsonp. If you cURL a Shopify ajax api location http://storename.domain.com/cart.json?callback=handler you will get a jsonp response. But something is breaking the same request in browsers. It appears to be related to compression? Here are some responses from each browser when attempting to call the jsonp as documented.

• How to remove accidental branch in TortoiseHg?

  - by msorens

  (I am a relative newcomer to TortoiseHg, so bear with me :-) I use TortoiseHg on two machines to talk to my remote source repository. I made changes on one machine, committed them, and attempted to push them to the remote repository BUT I forgot to first do a pull to get the latest code first. The push gave me a few lines of output, suggesting I may have forgotten to pull first (true!) and mentioned something like "abort: push creates new remote branches...". So I did a pull, which added several nodes to the head of my graph in the repository explorer. The problem is that the push I tried to do is now showing as a branch in the repository explorer. Looking from the server side (codeplex), it shows no sign of my attempted push, indicating this accidental branch is still local on my machine. How could I remove this accidental branch? I tried selecting that node in the graph then doing "revert" but it did not seem to do anything. I am wondering if it would be simplest to just discard my directory tree on my local machine and do a completely new, clean pull from the server...?

• Eclipse CDT: cannot debug or terminate application

  - by Paul Lammertsma

  I have Eclipse set up fairly nicely to run the G++ compiler through Cygwin. Even the character encoding is set up correctly! There still seems to be something wrong with my configuration: I can't debug. The pause button in the debug view is simply disabled, and no threads appear in my application tree. It seems that gdb is simply not communicating with Eclipse. Presently, I have the debug settings as follows: Debugger: "Cygwin gdb Debugger" GDB debugger: gdb GDB command file: .gdbinit Protocol: Default I should mention here that I have no idea what .gdbinit does; in my project it is merely an empty file. What is wrong with my configuration? Debugging When attempting to terminate the application in debug mode, Eclipse displays the following error: Target request failed: failed to interrupt. I can't kill the process, either; I have to kill its parent gdb.exe, which in turn kills my application. Running When running it normally, a bunch of kill.exes are called, doing nothing, while Eclipse displays the following error: Terminate failed. I can kill FaceDetector.exe from the task manager. Process Explorer This is what it looks like in Process Explorer (debugging left, running right):

• How to make a product catalog in C#?

  - by Ervin

  I need to develop a product catalog (about 4000 products) application, which would be given to clients on CD or DVD. The catalog exists in webpage format using PHP and MySQL. IMPORTANT: the application is given to clients who maight have old PC, old System. For minimal requirements I would put Windows XP and Internet Explorer 6 (if needed). I need the following features: 1 search option (after productID AND after keyword) 2 print option (by selecting multiple products) 3 shopping cart (making a list which will be sent to an email address if there is any Internet Connection on the computer) When I was asked to do it I had 2 days to realise a very basic version, so I took the whole website and exported it in HTML pages, and developed an application in C# which contains an embeded browser. So the whole website is now static and put on a CD. Everything fine so far. Now here are the problems: 1. the search option was realized by parsing the html files and reading the productID or looking for keywords inside of them. Put on a CD it was extremely slow (searching in 600MB of html files). FOR THIS I WOULD NEED A SOLUTION WITH A STATIC DATABASE (USING ACCESS OR SOMETHING) TO HAVE INDEXED ROWS, SO THE SEARCH COULD BE A VERY FAST ONE. 2. the printing option was a simply call of the embeded Internet Explorer print functions. Here are two problems: a) user needs IE7 for printing the website scaled (FIT TO PAGE), otherwise the edges of the page are cut down. b) users of this app does not have even the basic PC usage skills, so they can't set the printing settings, so there will appear in header and footer the page numbers and titles. QUESTION: can I set these settings from CSS for printing? 3. couldn't make a a shopping cart as I don't use a database, so I have static websites and content is inside the HTML. QUESTION: WHICH ARE THE BEST SOLUTIONS FOR THE PROBLEMS DESCRIBED ABOVE? PLEASE ANSWER EVEN IF YOUR ANSWER IS FOR ONE QUESTION ONLY. THANKS

• Why does my call to Activator.CreateInstance intermittently fail?

  - by Daniel Stutzbach

  I'm using the following code to access the Windows Explorer Shell's band site service: Guid GUID_TrayBandSiteService = new Guid(0xF60AD0A0, 0xE5E1, 0x45cb, 0xB5, 0x1A, 0xE1, 0x5B, 0x9F, 0x8B, 0x29, 0x34); Type shellTrayBandSiteService = Type.GetTypeFromCLSID(GUID_TrayBandSiteService, true); site = Activator.CreateInstance(shellTrayBandSiteService) as IBandSite; Mostly, it works great. A very small percentage of the time (less than 1%), the call to Activator.CreateInstance throws the following exception: System.Runtime.InteropServices.COMException (0x80040154): Retrieving the COM class factory for component with CLSID {F60AD0A0-E5E1-45CB-B51A-E15B9F8B2934} failed due to the following error: 80040154. at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandle& ctor, Boolean& bNeedSecurityCheck) at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean fillCache) at System.RuntimeType.CreateInstanceImpl(Boolean publicOnly, Boolean skipVisibilityChecks, Boolean fillCache) at System.Activator.CreateInstance(Type type, Boolean nonPublic) I've looked up the error code, and it appears to indicate that the service isn't registered. That's nonsense in my case, since I'm trying to access a service provided by the operating system (explorer.exe, to be specific). I'm stumped. What might cause Activator.CreateInstance fail, but only rarely?

• Design suggestions for creating document management structure using hidden shares.

  - by focus.nz

  I need to add some document management functionality into my software. Documents will be grouped by company name and project name. The folders need to be accessed by the application using the id numbers of clients/projects, but also easily browsed by the end user using windows explorer. Clients and Projects will be stored in a database. I am thinking of having the software create the folders using the friendly name and then using a hidden share with the id number for the software to access the files. The folder structure would be something like this --Company 1 (Company-1234$) -- Project 101 (Project-101$) -- Project 102 (Project-102$) -- Project 103 (Project-103$) -- Company 2 (Company-5678$) -- Project 201 (Project-201$) -- Project 202 (Project-202$) -- Project 203 (Project-203$) So in the example above there would be a company called "Company 1" with a ID of "1234". When browsing the folders using windows explorer the user would see \\ServerName\Documents\Company1 and you could also access the same folder from \\ServerName\Documents\Company-1234$ By using the hidden share, if the company name changes or its renamed for some reason it doesn't break the link in the application because its using the hidden shared based on the ID that never changes. Will having hundreds (maybe thousands) or hidden shares on a server provide a huge performance hit? Does any one have any suggestions or alternatives to provide this feature?

• Sending basic authentication information via form

  - by VolatileStorm

  I am working on a site that currently uses a basic authentication dialog box login system, that is the type of dialog that you get if you go here: http://www.dur.ac.uk/vm.boatclub/password/index.php I did not set this system up and am not in a position to easily/quickly work around it, but it DOES work. The issue however is that the dialog box is not very helpful in telling you what login information you have to use (that is which username and password combination), and so I would like to replace it with a form. I had been thinking that this wasn't possible but I wanted to ask in order to find out. Is it possible to set up an HTML form that sends the data to the server such that it accepts it in the same way that it would using this dialog box? Alternatively is it possible to set up a PHP script that would take normal form data and process it somehow passing it to the server such that it logs in? Edit: After being told that this is basic authentication I went around and have managed to find a way that works and keeps the user persistently logged in. However, this does not work in internet explorer. The solution was simply to redirect the user to: http://username:[email protected]/vm.boatclub/password/index.php But Internet Explorer removed it due to phishing uses about 3 years ago. Is there a way to use javascript to get the browser to access the site in this way? Or will I have to simply change my UI?

• AJAX vs ActiveX/Flash for browser-based game

  - by iconiK

  I have been following the usage of JavaScript for the past few years, and with the release of extremely fast scripting engines (V8, SquirrelFish Extrene, TraceMonkey, etc.) the possibilities of JavaScript have increased dramatically. However, the usage share of Internet Explorer coupled with it's total lack of support for recent standards makes me want to drop a bomb on Microsoft's HQ, as it creates a huge amount of problems for any website. The game will need to be pretty dynamic client-side, with animations and other eye-candy things, but not a full-blown game like those that run directly in the OS using DirectX or OpenGL. However, this might be a little stretch for JavaScript and will certainly feel extremely slow in Internet Explorer (given that the current IE engine can be hundreds of times slower than SFX; gotta see what IE9 will bring), would it be better to just do the whole thing in Flash? I know this means requiring the plug-in AND I have no experience whatsoever with Flash (other than browsing YouTube :P). It also means I can't just output directly from PHP, I would have to use XML or some other format to pass data to it (JSON is directly integrated in JS and PHP can deal with it easily). Another idea would be to provide an alternative interface just for IE, though I don't know how (ActiveX maybe? or with Flash, then why not just provide it to all browsers) or totally not supporting it and requiring the use of other browsers, although this is plain stupid from a business perspective. So here am I, wondering what approach to take and thus asking for your advice. How should I build the client-side? AJAX in all browsers, Flash in all browsers or a mix (AJAX for "modern" browsers and something else for the "grandpa": IE).

• Use of 'this keyword' javascript in IE ?

  - by Ron

  Is there a workaround for Internet Explorer to implement the functionality offered by 'this' javascript keyword to get the dom element that triggered the event? My problem scenario is : I have a variable number of text fields in the html form, like input type="text" id="11" input type="text" id="12" .. I need to handle the "onchange" event for each text field, and the handling is dependent on the 'id' of the field that triggered the event. So far I understand that my options are: 1) attach a dedicated event handler for each text field. so if I have n fields, i have n different functions, something like: input type="text" id="11" onchange="function11();" input type="text" id="12" onchange="function12();" but the text fields are added and removed dynamically, so a better way would be to have one generic function instead. 2) use the 'this' keyword like: input type="text" id="11" onchange="functionGeneric(this);" input type="text" id="12" onchange="functionGeneric(this);" But this option does not work with Internet Explorer. Can anyone suggest a work around for getting it work in IE or some other solution that can be applied here? Thanks.

• UML Modelling in C++Builder 2010 Professional

  - by Gordon Brandly

  I'd like to do some basic class diagram UML models in the Pro version of C++Builder 2010. Embarcadero has a C++Builder Features Matrix document, one line of which says "UML Code Visualization – at any time, get a UML model view of your source code" and has a check in the "Professional" column of that table -- I assume this means it should be available to me. Yet, when I open an existing project and do a View | Model View, there's nothing in the Model View window. The only diagram I can find is on the Graph tab of the C++ Class Explorer. I wouldn't call that a UML diagram myself -- is that what Embarcadero is referring to? Embarcadero's table shows that many UML diagrams are not available in Pro, but it looks to me like Class Diagrams should be available. Other lines in that same table indicate that both "Full two-way class diagrams with synchronization between code and diagrams" and "Diagram hyper-linking and annotations" are also supposed to be available in Pro. The Class Explorer graph is one-way only as far as I can tell, so I hope they're referring to something else I haven't been able to find so far. Thanks for any insight into this.

• How to run White + SL4 UATs through TeamCity?

  - by Duncan Bayne

  After experiencing a series of unpleasant issues with TFS, including source code orruption and project management inflexibility, we (meaning the project team of which I'm a part) have decided to move from TFS 2010 to TeamCity + SVN + V1. I've managed to get our MSTest component and unit tests running as part of every build. However, our UATs are failing, and I was hoping for some advice from the TeamCity community as to best practices w.r.t. running web servers and interacting with the desktop. Each of our UAT fixtures starts a web server to host the site, like this: public static void StartWebServer() { var pathToSite = @"C:\projects\myproject\FrontEnd\MyProject.FrontEnd.Web"; var webServer = new Process { StartInfo = new ProcessStartInfo { Arguments = string.Format("/port:9150 /path:\"{0}\"", pathToSite), FileName = @"C:\Program Files (x86)\Common Files\microsoft shared\DevServer\10.0\WebDev.WebServer40.EXE" } }; webServer.Start(); } Needless to say, this doesn't work when running through TeamCity, as the pathToSite value is different each time. I'm hoping there is a way of determining the path into which the the code is checked out prior to building? That would allow me to point the web server at the right place. The other issue is that our UATs use White to drive the Silverlight UI through an instance of Internet Explorer: _browserWindow = InternetExplorer.Launch("http://localhost:9150/index.html#/Home", "Home - Windows Internet Explorer"); _document = _browserWindow.SilverlightDocument; I've ensured that the TeamCity service is granted the ability to interact with the desktop, and I've set the build agent machine up to log in automatically (an open session is a pre-requisite for White to work properly). Is that all I need to do or are there additional steps required?

• How can I automatically elevate a COM interface used for automation?

  - by Jim Flood

  I have a Windows service built with ATL to expose a LocalServer32 COM interface for a set of admin commands used for configuring the service, and these can be used from VBScript for example: Set myObj = WScript.CreateObject("MySvc.Administrator") myObj.DoSomething() I want DoSomething to run elevated, and I would like the UAC prompt to come up automatically when this is called by the VBScript. Is this possible? I know I can run the script in an elevated command shell, and that I can use objShell.ShellExecute WScript.FullName, Chr(34) & WScript.ScriptFullName & Chr(34), vbNullString, "runas" for example, to run the VBScript itself elevated, and either of those work fine -- the COM method finds itself elevated. However, AFAIK getting an elevated Explorer window on the desktop is convoluted (it's not as simple as right-clicking Start/Accessories/Windows Explorer/Run as Administrator, which doesn't actually elevate.) I want a user in the local admin group to be able to drag-and-drop files and folders onto the script, and then have the script call the admin COM interface with those pathnames as arguments. (And I am hoping for something simpler than monkeying around with the args and using ShellExecute "runas".) I've tried setting UAC Execution Level to requireAdministrator in the service EXE's manifest, and setting Elevated/Enabled = 1 and LocalizedString in the registry for the MySvc.Administrator class, and these don't do the trick.

• Gacutil.exe successfully adds assembly, but assembly missing from GAC. Why?

  - by Ben McCormack

  I'm running GacUtil.exe from within Visual Studio Command Prompt 2010 to register a dll (CatalogPromotion.dll) to the GAC. After running the utility, it says Assembly Successfully added to the cache, and running gacutil /l CatalogPromotionDll shows that the GAC contains the assembly, but I can't see the assembly when I navigate to C:\WINDOWS\assembly from Windows Explorer. Why can't I see the assembly in WINDOWS\assembly from Windows Explorer but I can see it using gacutil.exe? Background: Here's what I typed into the command prompt for VS Tools: C:\_Dev Projects\VS Projects\bmccormack\CatalogPromotion\CatalogPromotionDll\bin \Debuggacutil /i CatalogPromotionDll.dll Microsoft (R) .NET Global Assembly Cache Utility. Version 4.0.30319.1 Copyright (c) Microsoft Corporation. All rights reserved.

• Created files on Archos 5 invisible on Windows Xp

  - by user352042

  I am fairly new to Android and this is my first post so I apologise in advance if I am breaking protocol or posting to the wrong board. Please feel free to move this post to somewhere more appropriate if required. I am developing for the 160 Gb Archos 5 Internet tablet. Not ideal as a development platform I know, but customer requirements mean we have no choice. It is running Android 1.6. I have updated the device firmware to the most recent available. Updating the version of Android is not an option at this point. Part of my app's requirement is to write information out to .txt files on the external storage directory so that these can be copied over the USB connection to a Windows XP PC using the Mobile media device (MTP) mode. I have followed all instructions I have come across carefully, eg I check that the storage is available using the technique described at http://developer.android.com/guide/topics/data/data-storage.html#filesExternal. However, althoug the files are created succesfully on the device (I can browse them and open them using the device's File Explorer - they are fine), when I connect the device to a Windows XP computer none of the directories or files I created appear and the size of their parent files suggest they do not exist. I have tried running over the ADB, checked logcat, tried a (signed) release version and even written a second test application which just creates a folder (this behaves the same, ie it creates the folder but this is not visible in Windows Explorer) - nothing anywhere gives me any suggestion as to what the problem might be. If anyone has heard of this before or has any ideas as to what else | could try to fix it please get in touch! We do not have any other devices to test on at the moment, although I hope to remedy this soon, customer permitting.

• When downloading a file using FileStream, why does page error message refers to aspx page name, not

  - by StuperUser

  After building a filepath (path, below) in a string (I am aware of Path in System.IO, but am using someone else's code and do not have the opportunity to refactor it to use Path). I am using a FileStream to deliver the file to the user (see below): FileStream myStream = new FileStream(path, FileMode.Open, FileAccess.Read); long fileSize = myStream.Length; byte[] Buffer = new byte[(int)fileSize + 1]; myStream.Read(Buffer, 0, (int)myStream.Length); myStream.Close(); Response.ContentType = "application/csv"; Response.AddHeader("content-disposition", "attachment; filename=" + filename); Response.BinaryWrite(Buffer); Response.Flush(); Response.End(); I have seen from: http://stackoverflow.com/questions/736301/asp-net-how-to-stream-file-to-user reasons to avoid use of Response.End() and Response.Close(). I have also seen several articles about different ways to transmit files and have diagnosed and found a solution to the problem (https and http headers) with a colleague. However, the error message that was being displayed was not about access to the file at path, but the aspx file. Edit: Error message is: Internet Explorer cannot download MyPage.aspx from server.domain.tld Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. (page name and address anonymised) Why is this? Is it due to the contents of the file coming from the HTTP response .Flush() method rather than a file being accessed at its address?

• LinqToSQL not updating database

  - by codegarten

  Hi. I created a database and dbml in visual studio 2010 using its wizards. Everything was working fine until i checked the tables data (also in visual studio server explorer) and none of my updates were there. using (var context = new CenasDataContext()) { context.Log = Console.Out; context.Cenas.InsertOnSubmit(new Cena() { id = 1}); context.SubmitChanges(); } This is the code i am using to update my database. At this point my database has one table with one field (PK) named ID. *INSERT INTO [dbo].Cenas VALUES (@p0) -- @p0: Input Int (Size = -1; Prec = 0; Scale = 0) [1] -- Context: SqlProvider(Sql2008) Model: AttributedMetaModel Build: 4.0.30319.1* This is LOG from the execution (printed the context log into the console). The problem i'm having is that these updates are not persistent in the database. I mean that when i query my database (visual studio server explorer - new query) i see the table is empty, every time. I am using a SQL Server database file (.mdf).

• DOMAIN REDIRECT PROBLEM WITH JQUERY / JAVASCRIPT

  - by GiovanniDema

  Hi guys, first time here. I got a strange problem. I have a fullscreen image scaler javascript (as GOTOCHINA website) that works very well on my website. Then, I purchased a domain redirect pointing on my website and when redirecting suddenly internet explorer 7 and internet explorer 8 give me this error Messagge: is not a valid argument. Line: 34 Char: 17 URI: http://*****/scaler.js The script is var db=document.body; var imag=document.getElementById('wallpaper'); var dbsize={}; var imgsrc=imag.src; var keyStop=function(e){ var e=window.event||e||{}; var tag=e.target.tagName.toLowerCase(); if(tag!='textarea'&&!(tag=='input'&&(e.target.type=='text'||e.target.type=='password'))){ if(e.keyCode==32||e.keyCode==39||e.keyCode==40){ if(e.preventDefault)e.preventDefault(); else e.returnValue=false; } } } if(this.addEventListener)window.addEventListener('keydown',keyStop,false); else window.attachEvent('onkeydown',keyStop); setInterval(function(){ window.scrollTo(0,0); if(imag.complete){ if(db.clientWidth!=dbsize.w||db.clientHeight!=dbsize.h||imag.src!=imgsrc){ imgsrc=imag.src; var dbsizew=db.clientWidth; var dbsizeh=db.clientHeight; var newwidth=Math.round(dbsizeh*(imag.offsetWidth/imag.offsetHeight)); var nextvar=dbsizewnewwidth?dbsizew:newwidth; imag.style.width=nextvar+'px'; } } },300); In other words when i open the official website everything's working correctly. When i open redirect domain pointing on official website... the previous error appears. The line is exactly this - imag.style.width=nextvar+'px'; Thanks in advance Giovanni
