• Oracle data provider hangs IIS worker process when web site is stopped

  - by Greg

  We're experiencing a nasty issue in Oracle 11g Release 2 where the w3wp process takes over and entire processor core, and debugging shows that the Oracle data provider is throwing ThreadAbortExceptions infinitely. A developer found this issue by doing the following: 1) Browse a web site that uses Oracle data connections locally (http://localhost/OracleWebSite) - we use IIS, not the ASP.NET dev server, for all of our sites. This ensures that the w3wp process is running and that an active Oracle pool of connections exists in the app pool. 2) Stop the web site (or perform a Rebuild All operation in Visual Studio on the web site in question). Our Oracle connection handling in the affected applications (all Oracle web apps) is well-established and robust. This issue does not occur if we disable connection pooling. This issue does not occur in Oracle 11g Release 1.

• How can I convert a specific .cs file into either a .bat or a .exe file?

  - by user2974969

  I am trying to convert around 1,900 .txp files (a proprietary Sony image format) to .png. However, the .exe program I am using to convert these files only allows me to select one file at a time. I am running Windows 7. There's a TXP.CS file in the 'src' folder of the program, so I figured that if I was able to turn that into an executable file, I'd be able to use it to mass convert these files to PNG. However, whenever I try to convert the file using csc.exe, I get the CS0246 error (the type or namespace name 'Tools' could not be found. Are you missing a using directive or an assembly reference?). I can't use Microsoft Visual Studio right now, so I'm hoping someone can walk me through this, or maybe convert the file to either a .bat or an .exe for me. Thank you. TXP.CS

• How to initialise a STL vector/list with a class without invoking the copy constructor

  - by Warpspace

  I have a C++ program that uses a std::list containing instances of a class. If I call e.g. myList.push_back(MyClass(variable)); it goes through the process of creating a temporary variable, and then immediately copies it to the vector, and afterwards deletes the temporary variable. This is not nearly as efficient as I want, and sucks when you need a deep copy. I would love to have the constructor of my class new something and not have to implement a copy constructor just to allocate my memory for the second time and waste runtime. I'd also rather not have to immediately find the class instance from the vector/list and then manually allocate the memory (or do something horrible like allocate the memory in the copy constructor itself). Is there any way around this (I'm not using Visual Studio BTW)?

• Why does Windows Explorer search freeze when I have an unrelated program paused in a debugger

  - by Evgeny

  While debugging my program, whether it's an ASP.NET application or a .NET console EXE and I have the debugger paused at a breakpoint I try to find a file in Windows Explorer. Either pressing WinKey+F or selecting search from the context menu freezes Windows Explorer - until I resume the program being debugged. My program has nothing to do with Windows Explorer! In fact, this happens in Visual Studio 2008 even with the simplest console EXE (WriteLine and ReadLine). I can't repro it with this simple EXE in WinDbg, but it does happen in with WinDb debugging an ASP.NET app. Why does this happen and how do I fix it? It's bloody annoying, especially when you don't realise what's going on. This is on Windows XP x64 SP2, running a .NET 3.5 application.

• HowTo parse numbers from string with BOOST methods?

  - by mosg

  Problem: Visual C++ 10 project (using MFC and Boost libraries). In one of my methods I'm reading simple test.txt file. Here is what inside of the file (std::string): 12 asdf789, 54,19 1000 nsfewer:22!13 Then I'm reading it and I have to convert all digits to int only with boost methods. For example, I have a list of different characters which I have to parse: ( ’ ' ) ( [ ], ( ), { }, ? ? ) ( : ) ( , ) ( ! ) ( . ) ( - ) ( ? ) ( ‘ ’, “ ”, « » ) ( ; ) ( / ) And after conversation I must have some kind of a massive of int's values, like this one: 12,789,54,19,1000,22,13 Maybe some one already did this job? PS. I'm new for boost. Thanks!

• Icons: How does a developer with no design skill make his/her application icons look pretty?

  - by Martin

  I probably spend far too much time trying to make my visual interfaces look good, and while I'm pretty adept at finding the right match between usability and style one area I am hopeless at is making nice looking icons. How do you people overcome this (I'm sure common) problem? I'm thinking of things like images on buttons and perhaps most important of all, the actual application icon. Do you rely on third party designers, in or out of house? Or do you know of some hidden website that offers lots of icons for us to use? I've tried Google but I seem to find either expensive packages that are very specific, millions of Star Trek icons or icons that look abysmal at 16x16 which is my preferred size on in-application buttons. Any help/advice appreciated.

• Background thread in C#

  - by Xodarap

  When the user saves some data, I want to spin off a background thread to update my indexes and do some other random stuff. Even if there is an error in this indexing the user can't do anything about it, so there is no point in forcing the main thread to wait until the background thread finishes. I'm doing this from a ASP.NET process, so I think I should be able to do this (as the main thread exiting won't kill the process). When I set a breakpoint in the background thread's method though, the main thread also appears to stop. Is this just an artifact of visual studio's debugger, or is the main thread really not going to return until the background thread stops?

• Crystal Reports Formula Workshop boolean condition to string

  - by Jay

  I'm currently trying to create a report using Crystal Reports that comes with Visual Studio 2008. I would like to include a field of type boolean on my report that shows a string rather than true or false. The string should contain either contain a € or a % sign. How would I go about doing this in the Formula Workshop? I've tried things like e.g. if {tblAankoopDetails.SoortKorting} = true then "€" else "%" However this never seems to work and results in warnings such as "The formula result must be a number". This should be fairly simple but this is my first go at using Crystal Reports. Help would be much appreciated. Jay

• How do I use the Microsoft VSTO interfaces?

  - by user557554

  hi, I would like to create an addin for microsoft outlook, and am using the visual studio tools to do so. However I am really struggling to get my head around the use of interfaces within the VSTO environment - the resources on MSDN show many useful looking interfaces, but I am unsure how to use these interfaces to access data. For example I am trying to add a new folder into an IMAP account but am finding it very difficult to work out how to get outlook to do so. Can anyone recommend any good resources for learning how to use VSTO (I have VSTO for dummies, but it doesn't cover the level of detail I need, I have been using MSDN, but I have found it doesnt offer much information on how to use the interfaces etc.) thanks.

• ssrs column groups disable multiple columns

  - by DKS

  I'm using ASP.NET 4.0 Visual Studio 2010 RC version Sql Server Report Services (SSRS) ReportViewer and are aware that columns only display on PDF export - not the preview. I want to use a matrix embedded in a table on a page that has multiple columns. I've done some testing and frustratingly found that if you have a tablix with at least one grouped column (even if there is only one displayed matrix-like column group) the columns seem to be disabled. Once I remove the tablix with a grouped column from the tablix from the report the report does multiple-columns. Does anyone know a way around this?

• Validation of dependent properties in a "live edit" WPF app

  - by Ryan Cromwell

  I'm working on an app which supports live editing. That is you update properties in one area and their impact is seen in another with hitting "apply". Happens to be a charting app. One such edit "group" allows specifying a range. A triple range in fact: High, Target and Low. Our validation is such that High must be greater than target, target must be greater than Low (rocket science). Our dilemma is that the visual experience is a bit jarring when someone wants to go from say 30,20,10 to 15,10,5. I'm curious if anyone has implemented a mechanism for this scenario that might fit well in our situation such that we don't "yell" at the user as they change the range values.

• Create Access databases programatically through vb.net

  - by user87225

  Let me preface this by saying that I know this is a stupid way to go about this, but it needs to be handled in this way. I need to make an application that from a master database creates a number of access database files (tables of a larger db), then these are manually given to users who fill in data, the database files are emailed back to a user who, through the application, combines them again. The only part of this that I am unsure about is problematically creating the access db's. I have read that through Microsoft Jet OLE DB Provider and Microsoft ADO Ext I can create them (the tables and data), but I also need forms. I have yet to start writing anything and this is away from my area of work, so any insight/links would be much appreciated. Also, I would hope to be able to write this in the free express version of visual studio. Are there components needed that would prevent me from this? Thanks.

• Listen to HTML/CSS events of web page

  - by David Metcalfe

  I'm looking for a way to listen for an event in the HTML/CSS of a webpage. Basically, a website I use at work lists queues and appointments, which flag as yellow/red based on the amount of time late on taking said appointment. Other than this visual aide, there is no alert of any kind, which is a failing point if one is juggling multiple windows and doesn't notice. What I would like to do is put together a simple way to watch for the tag ID or perhaps the flag hex color, and then alert me in a way of my choosing. The work environment is on OS X, so I presume I'm looking at an Objective-C centric solution unless Applescript is capable of doing this. Any help would be greatly appreciated.

• How do I find the root path of a website from a dll?

  - by Biff MaGriff

  I have a C# website. It references several compiled dlls. My dlls need to access folders on the website. How do I find the root path of the website from the dlls? I've tried System.Environment.CurrentDirectory - "C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE" Assembly.GetExecutingAssembly().Location - C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files...... I was going to use System.Web.HttpContext.Current.Server.MapPath() but System.Web.HttpContext.Current is null. Thanks!

• 64 bit COM(ActiveX) server

  - by Velja Radenkovic

  Hello, I have activex server exe that was building and registering fine on 32bit OS. I wanted to make 64 bit version of that exe by upgrading project to Visual Studio 2010 and changing platform to X64 which apparently doesn't work. Application itself works but I don't see it registered after running That.exe /RegServer I would appreciate any usable advice on migrating activex from 32 to x64. Code that is processing /RegServer param is below: if(lstrcmpi(lpszToken, _T("RegServer")) == 0) { _Module.UpdateRegistryFromResource(IDR_OUTDISKSARG, TRUE); nRet = _Module.RegisterServer(TRUE); bRun = false; break; } 32 bit activex is unuable for me since I have to load it in x64 .NET process.

• Versioning CommonAssemblyInfo.cs and MSBuild

  - by James Thigpen

  So I have a CommonAssemblyInfo.cs linked into all the projects in my solution and is dynamically generated by my rake/albacore scripts which is not checked into source control. I also have a CommonAssemblyInfo.cs.local for use when there is no ruby available, mainly to be used by devs. Is it possible to have a msbuild task or something that runs before any of the other project compilation that will copy CommonAssemblyInfo.cs.local to CommonAssemblyInfo.cs before trying to compile my solution? I hate having to have a command you have to just know about and type in order to open and buidl the solution in Visual Studio.

• How to save the world from your computer?

  - by Francisco Garcia

  Sometimes I miss the "help other people" factor within computer related careers. Sure that out there I could find many great projects improving society, but that is not common. However there are little things that we all can do to make this a better place beyond trying to erradicate annoynig stuff such as Visual Basic. You could join a cloud computing network such as World Community Grid to fight cancer. Write a charityware application such as Vim, improve an office IT infrastructure to support telecommuting and reduce CO2 emissions, use an ebook reader for saving paper... what else would you? which projects do you think can have an impact?

• C++ IDE for Linux with smart reference searching

  - by Dmitry Yudakov

  Is there an IDE supporting C++ with REALLY smart searching of references? By 'reference' I mean usage of a class (or its member), variable, function in the whole Project or Workspace. There's lots of IDE providing it. Some of them seem just to search for the text with same name giving lots of stuff, others are smarter and check the context (like class boundaries, namespace) but aren't accurate enough. The best I've tried so far was Visual SlickEdit, but still there's more to wish. class C1 { int foo; }; class C2 { int foo; }; For example in this situation when searching for C1::foo references I don't want C2::foo to be shown too. So, is there an IDE that would be so smart?

• System.Data.DataException thrown when launching application after install

  - by jwarzech

  I currently have a (Visual Studio 2008) installer that has a 'Primary output...' custom action under 'Install' with 'InstallerClass' set to false. During the install I get a System.Data.DataException. When I run the debugger I am getting an exception being thrown from a bit of database access code that runs when the application starts. The database access is using Windows Authentication and works correctly when the application is started manually. Is this something to do with permission settings not allowing db access when launched from the installer? (I'm out of ideas)

• MS WebBrowser + Embedded HTML Resource + res:// Protocol

Within the same application I have a WebBrowser control. I'd like to direct the WebBrowser control to display the HTML resource using the res:// protocol. But I can't figure out the exact format needed to address an embedded resource using this style of URL. Any ideas? Thanks!

• Why do my WPF UIElements NOT have OnPreview events?

  - by Matt.M

  I'm building a custom Silverlight UserControl which needs to listen to events using Preview/Tunneling, but for some reason the compiler is telling me they are not recognized or accessible. For example, I can add an event handler to MouseLeftButtonDown, but not PreviewMouseLeftButtonDown. This doesn't make sense because according to Microsoft (http://msdn.microsoft.com/en-us/library/system.windows.uielement_members(v=VS.100).aspx) all UIElements should have Preview events attached. Any ideas as to why this is happening? I'm using Visual Studio 2010 Trial, Blend 4 RC and .Net 4, if that makes a difference.

• C/C++ GUI framework to create distinctive window style

  - by genesys

  Hi! Can someone please tell me a GUI framework (for Windows. doesn't need to be cross platform) that allows me to specify the design of the UI elements very precisely? For example, the Windows and UI elements of Adobe products look different than other Windows applications. I'm looking for a framework that would allow me to create a GUI in that style - or any other style I invent, from the shape of the window, to the visual appearance of any scrollbar, button minimize/maximize buttons and so on. any recommendations? Thanks!

• Suggestions for a C++ IDE?

  - by AedonEtLIRA

  I know this is is a shifty question and really isn't easy to answer, but bare with me. For a while now I have been using Eclipse and doing Java programming. Now that I reach a point where I'm comfortable in Java, I wish to move on back into C++ and actually make something more than a single class that prints to terminal; and work in OpenGL :). So I wonder if anybody has a recomendation of IDE's that resemble or are as fluid as Eclipse? I am aware that Eclipse has a C++ plugin, but it really doesn't feel user friendly (at least to a pampered java programmer!). I have (I think I still have it?) a copy of Visual Studio 2005, but want to see if anyone has any better ideas. Thanks ~Aedon
