• DataGridView: can you add an unbound column to a Data Bound grid?

  - by Jack Johnstone

  I´m using Visual Studio 2008, C# DataGridView: can you add an unbound column to a Data Bound grid? It seems pretty simple, just select the properties ("DataGridView Tasks box") for the data bound DataGridView, and select Add unbound column. However, when in runtime there will be a System.FormatException - which I can understand, as I don´t know how to "initialize" the cells in the new unbound columns. I was planning initializing it programmatically via CellFormatting event - but so far I´m failing. Any tips? Just want to get it up and running in SOME way...

• Statically initialize anonymous union in C++

  - by wpfwannabe

  I am trying to statically initialize the following structure in Visual Studio 2010: struct Data { int x; union { char ch; const Data* data; }; }; The following is fails with error C2440: 'initializing' : cannot convert from 'Data *' to 'char'. static Data d1; static Data d = {1, &d1}; I have found references to some ways this can be initialized properly but none of them work in VS2010. Any ideas?

• Developing web app, question for mobile developers

  - by Stephen Kellett

  I'm going to develop a web app that I expect some people will also end up wanting to view on their phones. The UI will be fairly straightforward (no frames, just CSS/HTML). May have a bit of Flash, but not for the first version. My question is, for testing viewing of the web app on mobile devices what devices would you recommend that I test on (and thus, most likely, have to purchase)? Windows Mobile iPhone Android Other? or can I use emulators for any/all of these? Note that I'm not developing a platform (android, iPhone) specific app, just a web application that I expect will also be accessed from a mobile phone. I apologise if this seems like a niave/stupid question, but this hobby project is totally away from my commercial experience and I just don't know the answers to these questions, hence asking here. Thanks for reading.

• What's the advantage for 'attach to process' compared with 'Start Debugging'?

  - by Nano HE

  Hi. I am new to programming. I know only Start debug before. Maybe start debug suit for some small application develop better. I found Visual studio IDE provide another method of attach to process for using. When & Why must I use the attach debugging? Such as multi-threading application debugging. Client/Service application debugging. etc. Thank you.

• Premium Services - Ad blocker legal or illegal?

  - by René

  Ok, maybe thats kind of a stupid question. But let's try to get an answer. I'm building a Desktop Solution for an existing web service. That web service is only available without ads when you pay for a premium account. Would it be illegal when I block this ads in my Desktop Application? When you use this web service over the browser, every user has the chance to block ads with adblocker addons. So why not block this stuff in my Desktop Application?

• dependencies linking isnt enough?

  - by Russel

  In Visual Studio (C++) the other day, I was trying to build some example code and it would not work, even though I was pointing at the right include and lib directories. (I got linker errors) I asked a friend who fixed the problem by specifying the necessary .lib files in the General Properties-Linker-Input field of the project settings. My questions: Simply pointing to the directory with the .lib files is not enough? You need to specifically tell the linker which lib files to link? By listing the .lib files in the "additional dependencies" field, am I specifying exactly which static libs get built into the exe? If the answer to this is yes, then will these be the ONLY lib files that get built into the exe? Why is it called "additional" dependencies? Is there another place to specify lib files to include? Before I thought this was done by including the necessary header file? Thanks everyone! Russel

• Advantages of using WCF to work with Sharepoint Services WSS3.0?

  - by val

  Hi folks, what is your opinion or better off your practical experience using WCF to work with WSS instead of SP web services? I am writing some custom library for our software to store and retrieve files from WSS document libraries using sharepoint web services. I am not entirely happy with the performance of the sp web services - a bit too slow in many cases. Now, microsoft claims a significant improvements in WCF over remoting and I am looking into a good way to use WCF for my file services. Any suggestions or ideas? Maybe a good source of coding practices or blogs? Thanks a lot, Val

• Partial coverage of a return statement in C++/CLI

  - by brickner

  I have C++/CLI code and I'm using Visual Studio 2008 Team Suite Code Coverage. The code header: // Library.h #pragma once #include <string> using namespace System; namespace Library { public ref class MyClass { public: static void MyFoo(); static std::string Foo(); }; } The code implementation: #include "Library.h" using namespace Library; using namespace System; void MyClass::MyFoo() { Foo(); } std::string MyClass::Foo() { return std::string(); } I have a C# unit test, that calls MyClass.MyFoo(): [TestMethod] public void TestMethod1() { Library.MyClass.MyFoo(); } For some reason, I don't get a full code coverage for MyClass. The Foo() method has 3 uncovered blocks and 5 covered blocks. The closing curly brackets (}) are marked in orange - partially covered. I have no idea why is it partially covered instead of fully covered, and this is my question.

• Architecture for multiple web apps and databases.

  - by Matt

  We used to have only one web app, but now we are breaking it down into multiple ones. Each one will be packaged as separate product (web app) Some have things in common some do not. It was originally coded with php and using Postgresql 8.4 and CodeIgniter as the framework. I am looking for some good suggestions on how I should set up multiple web apps. They all have their own somewhat unique data. Some data in the databases can be common to some apps but not all. All the apps will be on one server and will have some kind of API to manipulate data. I want it to be structured such that one User account can access any product they purchase. (kinda like google accounts) I do not know if its a good idea to have multiple database, or just to have one big one. eventually we will be using S3 for some videos and other images. Your thoughts and suggestions are much appreciated.

• TFS 2010 build template failing to open in designer - how to fix?

  - by Duncan Bayne

  I can open the DefaultTemplate.xaml that was installed as part of our TFS 2010 RC setup. I created a copy of this template called ApplicationTemplate.xaml and modified it slightly, using the workflow designer in Visual Studio. Now, I can no longer open ApplicationTemplate.xaml. When I try, I receive many errors like the following: Error 2 Assembly 'Microsoft.TeamFoundation.Build.Client' was not found. Verify that you are not missing an assembly reference. Also, verify that your project and all referenced assemblies have been built. C:\Projects\tfs\Hydraulics\BuildProcessTemplates\ApplicationTemplate.xaml 1 1828 Miscellaneous Files However, I can still open and edit the DefaultTemplate.xaml file without any issues. Has anyone else come across this problem, & if so, did you manage to resolve it or did you have to recreate the template?

• Why is new showat attribute required when using code generation?

  - by Patrick Karcher

  When I generate code using T4 templates in Visual Studio 2010, I get the following error for each of my asp controls when I try to compile: Control "ddState" is missing required attribute "showat". I have never gotten this error in previous versions of .NET. Further, I don't get this error when I manually construct my pages either by dragging/dropping, nor do I get it when I type out the control text myself. When I generate code, I have to manually add showat="client" to my tag for the compiler to be happy. It was my understanding that I never had to explicitly specify this tag. The following: <asp:dropdownlist id="ddState" runat="server" showat="client" /> solves the problem. Why do I have to add this to generated code but not other times? (It's a VS-2010 webforms project, using VB, in case that makes a difference.)

• How can I improve the workflow between developer and designer with Expression Blend?

  - by Amenti

  We use WPF and Expression Blend 4. I'm trying to improve our workflow by tutoring one of our designers to use it for styling and animation. Slowly but surely I get the impression Blend in itself is to technical for the designer in question. I myself use it only occasionally (it's great for Visual States for instance) because a lot of things are easier done in code or not possible at all in Blend alone. It seems a developer with design experience is a lot more productive with it than a sole designer. Are there any good resources or advice as to how I can improve this workflow?

• Click-Once deployment is leaving multiple versions (yes, more than 2)

  - by Clyde

  I've got a click once application that is leaving all old versions on my disk. It's an internal corporate application that gets frequent updates, so this is a disaster for rapidly inflating our backup size. According to the docs and other SO questions, it is supposed to only leave the current and previous versions on disk. However, each time I deploy the project and upgrade a client, I get another copy of all exe/dll/data files. I'm making no changes whatsoever to the application, just pushing deploy again in Visual Studio. Any ideas? Updates: The problem seems to happen on both Windows 7 and XP. 64 bit windows and 32. I've done a diff of the folders where the version is installed and the following files are different: MyApp.exe.manifest MyApp.exe.cdf-ms MyDll1.cdf-ms MyDll2.cdf-ms No actual executable files are different, nor the MyApp.manifest, MyDll1.manifest, etc.

• What color scheme do you use for programming?

  - by EndangeredMassa

  I get a lot of attention at work because I am the only one who bothered to change the default color settings in Visual Studio. I just modified them myself. I can provide the settings file if anyone cares to import it. Here's an example of how it looks. It reminds me of DOS/BASIC programming before I actually knew how to program. I also find it to be very readable. What color schemes do you use?! EDIT: To clarify, I only edited the text settings. The windows and panels of VS2005 are still the windows default.

• is it possible to include a binary in my project and use it?

  - by Adam S

  I have a binary that's used as a command-line tool to manipulate some files - tool.exe. I would like to include this in my Visual Studio 2008 project and use it from my C# code. I have it in a folder called "Resources" which also has some other files my project uses. I would like to do something like Process myproc = Process.Start("Resources/tool.exe"); but I believe C# has an issue with this because it's looking in the file system rather than the project. How can this be done?

• Is installing Rational Developer for Power Systems on Ubuntu recommended?

  - by ZS6JCE

  I am interested in installing Rational Developer for Power 8.0.3 (RDPi) on Ubuntu 12.04. I would like to know if other Ubuntu users have run into issues? Is it recommended or should I just stick to using RDPi in Windows 7 in VirtualBox? I have done some research, but could not divine a solution. From IBM's Developerworks website: Ubuntu clients are obviously missing from the list. While not officially supported, we have had some success in running ... on Ubuntu 10.04 LTS and later. Detailed installation instructions for the supported operation systems can be found here.

• How would you approach developers you don't already know as a developer to offer them a position? [closed]

  - by Kit Sunde

  We've been trying to find a second developer for the company and have posted job ads online but so far there have been no developers that have been interested, and only a single one that has some experience in Python (that failed a fairly basic practical). It seems like the it's really difficult to find decent people here in Singapore, even reasonable juniors that you can teach. I'm contemplating whether I should go reach out directly to people on Stack Overflow and github and in the hopes that they are interested. I'm thinking I would message the person with only a few sentences, stating the they seems capable from their online presence and that I'd like to work with them. Is this kosher? I know I dislike recruiters and unsolicited mail just as much as the next guy.

• VS2005 and VSS. Should .exes, .dlls, pdbs, .resource and generated .xml files go in VSS?

  - by Velika

  It seems like the following type of files need to be writable to be able to compile a solution. .exe .dll .pdb (if debugging) .resource (?) .xml (at least the system generated ones. I'm not sure if they are just all XML documentationf iles) If they were checked in and could only be overwritten by the compiler by the person who had them checked out, then checking them into sourcesafe and requiring a checkout to modify them, which is attemtped by the compiler each time you run, would interfer with other developer's ability to debug and run. What is the best practice? It seems like VSS automatically adds everything.

• How to handle images folder with many images

  - by Billy

  I'm developing a new aspnet website with 200k images in a /Images/ -folder. Many operations in Visual Studio is slow because it access the folder, adding a web service takes 10 minutes. The images is not checked into scm (svn). How should I structure the tree of code, to improve performance in VS? It would also be neat if not all developers needed to copy 200k images to their local disk to be able to develop on the site. Images as DB blobs is not an option.

• Windows batch file: is there a way to add an "and"?

  - by Beska

  The short version: is there a way to to write an "and" clause in a batch file? The slightly longer version: I've inherited a Visual Studio project that creates a dll and then copies that dll to another location. As a post build step, VS runs the following script. if not '$(ConfigurationName)' == 'DebugNoSvc' goto end xcopy /Y $(TargetDir)*.config $(ProjectDir)..\myService\bin\Debug xcopy /Y $(TargetDir)*.config $(ProjectDir)..\myService\bin\DebugNoSvc :end It looks like there's a problem when the project is compiled as Debug, since it doesn't do the copy (I'm guessing that at some point the middle section got updated, but the if clause didn't.) Is there an easy way to an "and" clause in batch?

• How can I listen for the deletion of a ProjectItem via DTE?

  - by Will

  I've got a designer that relies on the existence of other solution items. If one of those items is deleted the designer crashes and you have to edit as XML to fix. Not exactly user friendly. I do, however, have the DTE object representing the instance of Visual Studio, as well as the ProjectItems I am dependent on. Is it possible to, somewhere in the depths of the DTE, register a listener for the deletion of that ProjectItem? And, if so, How would I do it?
