• "Unable to start program" on Debug Immediately After Successful Build

  - by TZ_Geek

  When I try to run my first application with the debugger, I get a pop up which says: Visual C__ 2008 Express Edition This project is out of date: ProgName - Debug Win32 Would you like to build it? [Yes[ [No] [Cancel] [ ] Do not show this dialog again? I find this somewhat bothersome, because the very last thing that I did just before that was build the application. And the build did complete successfully (immediately before I clicked on Start Debugging -- F5.) The second time I pressed with wrong cilck on the Answer [No] on the same msg Now, I can't compile my apps What exactly does "do not show this dialog again" mean? It sounds to me like its going to remember my answer and use the same answer every time this situation occurs in the future. I did some stuffs like "Clean Solution" then "Build Solution" then "Start Debugging" ,but the same problem what's the solution ,how can I reset this message to make it work again .

• organize using directives, re-run tests?

  - by Sarah Vessels

  Before making a commit, I prefer to run all hundred-something unit tests in my C# Solution, since they only take a couple minutes to run. However, if I've already run them all, all is well, and then I decide to organize the using directives in my Solution, is it really necessary to re-run the unit tests? I have a macro that goes through all files in the Solution and runs Visual Studio's 'Remove and Sort' command on each. In my understanding, so long as all projects still build after using directives are changed around, things should be fine at runtime, too. Is this correct thinking?

• Change namespace/filesystem folder names in Visual Studio

  - by Rosarch

  I'm trying to change a namespace in Visual Studio. My folder structure looks something like this: GameAlpha/ GameAlpha.sln GameAlphaRelease/ GameAlphaTest/ GameAlphaLevelEditor/ These include namespaces like GameAlphaRelease. I want to change all this to GameBetaRelease. Before this process, it built fine. First, I changed the solution and project files from Alpha to Beta. Then, I did a "find-replace-all" on the namespace. Finally, I went through the properties of each project and changed the "Assembly Name" and "Default Namespace" to the appropriate Beta title. However, now the solution does not build. The error is: GameAlpha.accessor: The reference to 'GameAlpha.exe' was not found in the list of this projects references. (Project: GameBetaTest) What am I doing wrong? If I remove project GameBetaTest, the solution builds just fine. Also, what is the preferable way to change the names of the folders in the file system?

• Manage Foreign key and Drop downlist for optional field in .NET

  - by Brij

  What is the best way to handle following situation? A dropdown(for master table) is optional in a particular form. But, In database table the field is constrained with foreign key. If user don't select from dropdown then It creates problem because of foreign key. One solution is to create default option in master table and use it in case of blank selection. but in dropdown, we need to handle this to show on top. Is it perfect solution? Is there any other optimized solution for this? Thanks

• Is it possible to add a New Project Wizard with a VSPackage?

  - by Gerald

  I have a VSPackage for Visual Studio 2008 that I created for adding some editor and custom language functionality. I also have a need to add a new project/solution wizard to create a new Solution and a complex series of C++ projects to the solution. I know I can do this using a "Custom Wizard", but I would be much happier if I can implement this within my VSPackage using C# instead. So I guess the main question is, is it possible to add an entry to the Project Types dialogs in Visual Studio from a VSPackage? Or is the "Custom Wizard" and JScript my only option here? And if it's possible, where can I find information and/or samples on how to accomplish this?

• Cannot change the target CPU to x86 Or x64 in Visual Studio 2005

  - by geekzilla

  I am trying to build a website application and specify the target CPU as x86 instead of Any CPU. The only choices I have in Configuration Manager under the "Active solution platform:" drop-down list are: "Any CPU", "Edit..", and "New...". In the "Project Contexts" portion of the "Configuration Manager" window, it lists 3 columns: "Project", "Configuration" and "Platform". Under the "Platform" column, my only choice is ".Net". when the "Active solution configuration" is set to, "Debug". When the, ""Active solution configuration" is set to "Release", then I can choose either, ".Net" or "Any CPU" under the "Platform" column. I am using Visual Studio 2005 Professional Edition. This website was previously built using Visual Studio .NET and was recently upgraded using the Visual Studio 2005 Professional Edition Upgrade Wizard. I need to target x86 specifically because the are components used in the project that are only x86 compatible.

• Visual Studio Extensions

  - by John Maloney

  I have a project that generates text (representing an interface and a class) based on metadata. I would like to take this generated code and insert it as a new class and interface directly into the currently opened solution under a specific project and directory. I will create the menu tool that will generate the class but what I don't know how to do is gain access to the following items from within my custom Visual Studio Extension: Iterate the current solution and find a project to dump the generated code into. Open a new file window within Visual Studio and inject the generated text that comes from my tool directly into that window. Create a new folder in a specific project within the current solution from within my custom extension. EDIT - To clarify I need to open a new file (e.g. Right Click on a Project - Add - New Class) and insert text into it from within my custom Visual Studio Extension. Thanks

• Best way to hide a window from the Alt-Tab program switcher?

  - by chaiguy1337

  I've been a .NET developer for several years now and this is still one of those things I don't know how to do properly. It's easy to hide a window from the taskbar via a property in both Windows Forms and WPF, but as far as I can tell, this doesn't guarantee (or necessarily even affect) it being hidden from the Alt-Tab dialog. I've seen invisible windows show up in Alt-Tab, and I'm just wondering what is the best way to guarantee a window will never appear (visible or not) in the Alt-Tab dialog. Update: Please see my posted solution below. I'm not allowed to mark my own answers as the solution, but so far it's the only one that works. Update 2: There's now a proper solution by Franci Penov that looks pretty good, but haven't tried it out myself. Involves some Win32, but avoids the lame creation of off-screen windows.

• Best way to implement a Rest API with PHP on Wamp web server

  - by DomingoSL

  Hello, i own a web server running windows (WAMP). I want to know the best way to implement a Rest API (a very simple one) in order to let a user do something. Diagram flow: I have programming skills, in fact, i developed some time ago a web server in VB6 who process the querys and when it find the command (http:/serverIP/webform.php?cmd=run&item=any) it do something, but know i really want to develop a solution using the WAMP server. Some people consider the solution of executing a exe when a command is detected a bad solution for security issues, but this specific proyect i have is for the use of only some people (trusted people) who dont have intentions of hacking the server. So, what do you think? Remember: Its not a public API, its for some people and some programs who will use the API Its a very simple one, only one command using POST or GET. Thanks

• How to share WinForms and code between 2 projects

  - by Richard Bysouth

  Hi I have a working Windows Forms app (split into an EXE and a few DLLs). Now I've been asked to look at creating another app (MyAppLite) that has only a very small subset of the functionality. Think of it as similar to MS Word Viewer vs. MS Word. Everything that I need to build MyAppLite is contained in the main solution - essentially I need to use a couple of the WinForms and whatever bits in the DLLs they call into. What would be the best way to do this? I was thinking of creating another Project in my solution for MyAppLite, then adding the necessary source files as links (using Add Existing Item Add As Link in Solution Explorer). I definitely wouldn't want to maintain 2 copies of the source code. FYI it's a .NET 2.0 VB app, using VS2008. thanks Richard

• jQuery event handler queue

  - by resopollution

  Overview of the problem In jQuery, the order in which you bind a handler is the order in which they will be executed if you are binding to the same element. For example: $('#div1').bind('click',function(){ // code runs first }); $('#div1').bind('click',function(){ // code runs second }); But what if I want the 2nd bound code to run first? . My current solution Currently, my solution is to modify the event queue: $.data(domElement, 'events')['click'].unshift({ type : 'click', guid : null, namespace : "", data : undefined, handler: function() { // code } }); . Question Is there anything potentially wrong with my solution? Can I safely use null as a value for the guid? Thanks in advance. .

• I need an algorithm to find the best path

  - by user242635

  I need an algorithm to find the best solution of a path finding problem. The problem can be stated as: At the starting point I can proceed along multiple different paths. At each step there are another multiple possible choices where to proceed. There are two operations possible at each step: A boundary condition that determine if a path is acceptable or not. A condition that determine if the path has reached the final destination and can be selected as the best one. At each step a number of paths can be eliminated, letting only the "good" paths to grow. I hope this sufficiently describes my problem, and also a possible brute force solution. My question is: is the brute force is the best/only solution to the problem, and I need some hint also about the best coding structure of the algorithm.

• Programmatic resource monitoring per process in Linux

  - by tuxx

  Hi, I want to know if there is an efficient solution to monitor a process resource consumption (cpu, memory, network bandwidth) in Linux. I want to write a daemon in C++ that does this monitoring for some given PIDs. From what I know, the classic solution is to periodically read the information from /proc, but this doesn't seem the most efficient way (it involves many system calls). For example to monitor the memory usage every second for 50 processes, I have to open, read and close 50 files (that means 150 system calls) every second from /proc. Not to mention the parsing involved when reading these files. Another problem is the network bandwidth consumption: this cannot be easily computed for each process I want to monitor. The solution adopted by NetHogs involves a pretty high overhead in my opinion: it captures and analyzes every packet using libpcap, then for each packet the local port is determined and searched in /proc to find the corresponding process. Do you know if there are more efficient alternatives to these methods presented or any libraries that deal with this problems?

• javascript to launch only ONE window for a Java applet with a given URL

  - by Jonathan Dugan

  I need a javascript solution to launch only one window, with a Java Applet in it, for a given URL. I found a solution posted here on Stack Overflow - here: http://stackoverflow.com/questions/528671/javascript-window-open-only-if-the-window-does-not-already-exist But it doesn't seem to work .. I get Error: launchApplication.winrefs is undefined Line: 29 I can't seem to post the code in this little box and make it look right below, so the code (my working code, plus the solution from above) is here: http://pastie.org/833879 Where is the error? As I understand it, the hash or array or whatever I use to store the called references to the windows opened this way will be lost if the calling window is closed. Is there a way to make this work even if the calling window is closed and reopened? To basically ask the browser: "Do you have a window open with the following URL?" and if so, "What is the reference to that window?" (so I can raise it).

• Using Session Bean provided data on JSF welcome page

  - by takachgeza

  I use JSF managed beans calling EJB methods that are provide data from database. I want to use some data already on the welcome page of the application. What is the best solution for it? EJBs are injected into JSF managed beans and it looks like the injection is done after executing the constructor. So I am not able to call EJB methods in the constructor. The normal place for EJB call is in the JSF action methods but how to call such a method prior to loding the first page of the application? A possible solution would be to call the EJB method conditionally in a getter that is used on the welcome page, for example: public List getProductList(){ if (this.productList == null) this.productList = myEJB.getProductList(); return this.productList; } Is there any better solution? For example, in some config file?

• Maths: Determining angle in 3D space

  - by 742

  I hope this is the proper location to ask this question which is the same as this one, but expressed as pure math instead of graphically (at least I hope I translated the problem to math correctly). Considering: two vectors that are orthogonal: Up (ux, uy, uz) and Look (lx, ly, lz) a plane P which is perpendicular to Look (hence including Up) Y1 which is the projection of Y (vertical axis) along Look onto P Question: what is the value of the angle between Y1 and Up? As mathematicians will agree, this is a very basic question, but I've been scratching my head on walls now for at least two weeks without being able to visualize the solution... maybe now too old for finding solutions to school exercises. I'm looking for the scalar trigonometric solution, not a solution using a matrix. Thanks.

• Upgrade from .NET 2.0 to .NET 3.5 problems

  - by Bashir Magomedov

  I’m trying to upgrade our solution from VS2005 .NET 2.0 to VS2008 .NET 3.5. I converted the solution using VS2008 conversion wizard. All the projects (about 50) remained targeting to .NET Framework 2.0., moreover if I’m changing target framework manually for one of the projects, all referenced dll (i.e. System, System.Core, System.Data, etc. are still pointing to Framework 2.0. The only way to completely change targeting framework I found is to remove these references and refer them again using proper version of framework. Doing it manually is not best choice I think. 50 projects ~ 10 references each ~ 0.5 minutes for changing each reference is about 5 hours to complete. Am I missing something? Are there any other ways of converting full solution from .NET 2.0 to .NET 3.5? Thank you.

• Looking for an elegant way to store one-to-many relationship in coredata when order is important

  - by Eric Schweichler

  I've been trying to come up with a way to solve my problem, but every solution I can think of is messy and makes me want to retch. I have a one-to-many relationship, consisting of a Team object that can have many Member objects. When I built my data model using Xcode, I was given the default NSSet in which to store the member objects, Unfortunately Sets are not ordered and I need to preserve the order of the Member objects and I need to know if there are empty spaces between Members. I thought of Using an NSArray in place of the NSSet and creating a dummy Member object in my data store that I could use to mark vacant a spot between to Member objects, but that solution really feels like too much of a hack to me. Since I'll always have to filter out this dummy Member from any queries. An NSDictionary would be perfect as I could store the Member object references and their positions as Object-Key pairs, (taking care of both order and vacancies) but apparently CoreData does not support NSDictionary. Has anyone had a similar need, and devised a simple solution?

• Website settings for running visual web as root?

  - by Curtis White

  Scott Gu explains how to run visual web developer using a root path, here: http://weblogs.asp.net/scottgu/archive/2006/12/19/tip-trick-how-to-run-a-root-site-with-the-local-web-server-using-vs-2005-sp1.aspx This worked exactly as he described in one instance for me. But, today I do not see this option. More over, I do not think I have a solution file, and I think that has something to do with it. I'm aware there are web application projects and web site model, and web site model is basically just a "directory". But can web site model, also, have a solution file for this setting or not a solution file? What determines that? I am interested in using this method on on a web site, i.e directory only model.

• Need Magic jQuery Replacement for Selectbox Dropdown Form Element. Thank you!

  - by PlasmaFlux

  Hello! I'm stuck on a problem and, after what seems like days of searching for a solution, I'm reaching out to Stack Overflow for help. I'm trying to replace a standard dropdown form element with a Textbox and a Div containing an unordered list. I'd prefer to have the solution be based on jQuery, but am open to alternatives. I've found a couple jQuery plugins that -almost- do what I need, but are far enough from being a real solution that I need to keep looking. Here's an image of what I'm going for: I'd like the dropdown to look as pictured, and when an element is selected (with mouse or keyboard), have just the first line handed back into the textbox (and not be editable). I'd also like to populate a hidden input field with a value that will be used on Submit. I'm pulling my hair out over this one. Any help and guidance will be most appreciated! Thanks! ~PF

• TFS and team project portal question

  - by DotnetDude

  The team explorer for my project looks like this: mytfsserver\mycollection -- Project 1 solution -- Project 2 solution -- Project 3 solution When I right click on one of the solutions and do a "Show Project Portal", I see the following hierarchy: mycollection - WSS site Project 1 site with dashboard (appears to be a MOSS site) Project 2 site with dashboard (appears to be a MOSS site) Project 3 site with dashboard (appears to be a MOSS site) Are the dashboard sites MOSS sites? If I want to create a wiki, do I have to create a subsite with the wiki template under each of the Project sites? Can someone point me to a document/video that talks about the sites that area created by TFS by default?

• Sanitize Content: removing markup from Amazon's content

  - by StackOverflowNewbie

  I'm using Amazon Web Service to get product descriptions of various items. The problem is that Amazon's content contains mark up that is sometimes destructive to the layout of my web page (e.g. unclosed DIVs, etc.). I want to sanitize the content I get from Amazon. My solution would be to do the following (my initial list so far): Remove unnecessary tags such as div, span, etc. while keeping tags like p, ul, ol, etc. Remove all attributes from all the tags (e.g. seems like there are style attributes in some of the tags) Remove excess white space (e.g. multiple spaces, carriage returns, new lines, tabs, etc.) Etc. Before I go off trying to build my solution, I'm wondering if anyone has a better idea (or an already existing solution). Thanks.

• How can I extract System.Net.Mail from Mono and rename the namespaces?

  - by JL

  Microsoft's implementation of System.Net.Mail does not provide a robust mailing solution. I would like to use Mono's implementation of System.Net.Mail instead, however that namespace is embedded in the System.dll shipped with Mono, and has exact same namespaces as the original .net framework. What I would like to do is instead extract System.Net.Mail from the mono solution and rename namespaces to Mono.System.Net.Mail. Then I can compile this in its own DLL and finally have a mailing solution that works! Can anyone tell me how this can be done?

• VS2010 Publish Profiles -- Where are they stored?

  - by Jeff S

  We have set up a few Publish Profiles that are used to deploy web apps to various servers, and it all works great with 1-click deployment. However, w find that even though the entire solution is under source control (svn), the profiles do not seem to be carried over, so we need to re-create the profiles on each developer's machine manually. It seems, since the profiles only exist for the solution currently loaded, that they must be stored in the solution files somewhere, but they do not carry over when someone else does an update to pull down the code. I'm guessing whatever file they're in is one we aren' covering in the source control project, but I haven't been able to figure out which one. Someone must know where the Publish Profiles are stored -- is there any way to copy them from machine to machine so we don't have to retype them for each developer?

• Is it possible to have an out-of-process COM server where a separate O/S process is used for each ob

  - by Tom Williams

  I have a legacy C++ "solution engine" that I have already wrapped as an in-process COM object for use by client applications that only require a single "solution engine". However I now have a client application that requires multiple "solution engines". Unfortunately the underlying legacy code has enough global data, singletons and threading horrors that given available resources it isn't possible to have multiple instances of it in-process simultaneously. What I am hoping is that some kind soul can tell me of some COM magic where with the flip of a couple of registry settings it is possible to have a separate out-of-process COM server (separate operating system process) for each instance of the COM object requested. Am I in luck?
