  • DLL response is too slow in Visual Studio [Resolved]

    - by magsto
    I use a 3rd party DLL in my VB.NET project (VS2005) that responds to slow and give wrong values in debug mode. In run-time mode everything works as expected. I do understand that there are something going on in the debug mode which makes the DLL communication slow. This behavior makes it hard to debug the application correctly. Is there any way to force VS to communicate with the DLL in "run-time" mode during debugging but let the rest of the project be in control of the debugger? I found a setting that resolved my issue: Project Properties Debug Enable Debuggers select "Enable unmanaged code debugging". Now the DLL communication flowed smoothly. The DLL I use is a middleware between my app and a USB device. There is no Debug/Release version of the DLL.

  • code folding in Visual Studio for F#

    - by Yin Zhu
    I find that I tend to write long source files in F#. Some open source projects in F# also have long source files, e.g. FPersec and F# for excel. So it would be very helpful if code folding (even very limited support) is available in VS for F#. E.g. in a module, we can fold out functions that are stable, only leave functions that are subject to change unfold. Is this feature easy to be supported, e.g. by a third party vendor?

  • Visual Studio 2008 awful performance

    - by Nima
    Hi, I have ported a piece of C++ code, that works out of core, from Linux(Ubuntu) to Windows(Vista) and I realized that it works about 50times slower on VS2008! I removed all the out of core parts and now I just have a piece of code that has nothing to do with the hard disk. I set compiler parameters to O2 in Project Properties but still get about 10times slower than g++ in linux! Does anybody have an idea why it is this much slower under VS? I really appreciate any kind of hint! Thanks,

  • Change column names of a cube action as they appear in Visual Studio

    - by hermann
    the title pretty much says it all. I have a cube with data in it and I have yet to find a way to change the column names. They appear in a very ugly manner like [cubeName].[$dimension.columnName]. I have tried everything I know and anything I found on the web but nothing seems to be working. What I tried to do in most cases is create an Action in the Actions tab and write some MDX query language in there. No results whatsoever. As if the action is never run. Does anyone know how to do this? I've spent about 3 days trying to figure this out. Thank you.

  • Visual C++ 2008: Finding the cause of slow link times

    - by ckarras
    I have a legacy C++ project that takes an annoyingly long time to build (several minutes, even for small incremental changes), and I found most of the time was spent linking. The project is already using precompiled headers and incremental compilation. I have enabled the "/time" command line parameter in the hope I would get more details about what is slowing the linker, and got the following output: 1>Linking... 1> MD Merge: Total time = 59.938s 1> Generate Transitions: Total time = 0.500s 1> MD Finalize: Total time = 7.328s 1>Pass 1: Interval #1, time = 71.718s 1>Pass 2: Interval #2, time = 8.969s 1>Final: Total time = 80.687s 1>Final: Total time = 80.953s Is there a way to get more details about each of these steps? For example, I would like to find if they are spending most time linking to a specific .lib or .obj file. Also, is there any documentation that explains what each of these steps do?

  • Generate accessors in Visual C++ 2008

    - by gramm
    Hi, I'm trying to generate the accessors and mutators for my variables automatically, but just can't find a way. I tried the right-click/refactor... solution, but the refactor item doesn't appear. I'm not in the mood right now to learn how to write a macro to do this, and I don't have the money to buy a commercial solution (internship student). Any help is welcome, I don't feel like writing all my get/set by hand. note : it's C++ so the {get;set} syntax doesn't work (or does it ?).

  • Visual Studio 2008, MSBuild: "replacement" projects

    - by liori
    Hello, My solution has a library project which needs a special environment to be built (lots of external libraries and tools)... but it is not vital to our application. We'd like to avoid installing these tools when not necessary (most of our developers work on other parts of code). We have created another project which has the same API, but has an empty implementation and is compilable without those external tools. I'd like to be able to easily switch between those projects and still get all the references in other projects correct. I don't know VS/MSBuild very well, but willing to learn whatever is necessary. Is it possible? I am looking for ideas... We're using Subversion, and solutions involving some hacks inside VCS are also welcome.

  • Importing a DllMain winapi .dll into Visual Studio project C++

    - by Bad Man
    I have the .def file, .lib file, the .dll, the source files. It's using WINAPI DllMain, all its functions follow that. It's like this: BOOL APIENTRY DllMain( HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ) { return TRUE; } extern "C" { int WINAPI DoSomething() { return -1; } int WINAPI DOSOMETHIGNELSE!() { return 202020; } }; IN the project settings linker I added the .lib file. There is no header file for the actual functions in the extern "C" part. I include windows.h try to call DoSomething() but doesnt know what it is.

  • visual studio 2010 add reference version missing

    - by Noel
    In VS2008 when I add a reference to a dll e.g log4Net I get the following in csproj <Reference Include="log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=1b44e1d426115821, processorArchitecture=MSIL"> <SpecificVersion>False</SpecificVersion> <HintPath>..\..\lib\log4net\log4net.dll</HintPath> </Reference> In VS2010 when I add a reference to a dll for the first time e.g log4Net I get the following in csproj (i.e no version number etc) <Reference Include="log4net"> <HintPath>..\..\lib\log4net\log4net.dll</HintPath> </Reference> If I remove reference and add a second time the same details as in VS2008 is there (Version etc) Anyone know why version number etc not present the first time I add a reference and why it is present on secound time reference added?

  • Visual Studio 2008 closes unexpectedly

    - by Jose
    I don't know if I can really get an answer to this question, but it really irks me and I would like to know if someone has an idea how to arrive to an answer. I have a pretty large solution in VS 2008 that maybe every week/every other week whenever I click properties to get to the project properties the IDE closes without warning. After that happens it will close EVERY time I try and view the properties. At that point I try and delete the .suo file, I resize the IDE, I close the tabs within the project, I restore default VS Settings(when I'm desperate). Eventually 20-30 minutes later I can actually view the properties. I haven't figured out exactly what fixes it, seems to be different every time. Once it's "fixed" I can't break it again so I can figure out what "fixed" it. This seems to be project specific, because I can view properties of other projects while this project is misbehaving. I guess my first question is, does VS log reasons for closing unexpectedly? Can I find out what the offending reason behind this is? The main frustration is I don't know that cause, nor the cure. Any ideas?

  • C# / Visual Studio - Object is null unless I have a Breakpoint

    - by user576611
    Hi Everyone, I'm specifically using the Google Contacts API at the moment, but this could be true of other scinarios as well. I have the following code: Contact newContact = new Contact(); When I let the code run without any breakpoints, I get a NullReferenceException on all of the properties of this object. However, if I put a breakpoint just after this line, I can see all of the properties have been initialises and the rest of my code executes fine. Any idea's would be greatly appreciated

  • Visual Studio 2008 Navigate Forewards/Backwards Buttons Don't Work As Expected

    - by TheCloudlessSky
    I just installed VS2008 on my new Win7 box. I have Navigate Backwards and Navigate Forwards buttons on my tool bar. When I change between documents, I do NOT see a list drop down for each of the buttons like should be seen here after opening multiple documents and switching between their methods: How it should work. Instead, I just see the buttons without drop downs. I find that navigating forwards and backwards doesn't work as it should. I should be able to click in different lines of the code and press the nav back/forwards buttons to jump between lines. This is not the case. Any suggestions? Thanks in advanced. PS - I installed SP1 just to see and nothing changed.

  • Which Visual Studio 2010 edition for sole developer

    - by bufferz
    I am the sole .net developer for a small company. My projects span many .net technologies including WinForms, WPF, SQL, XNA, Linq, WCF, WTF?, and others. I struggle staying on top of all these projects so I'm looking to make my life easier with the release of VS2010. Without a mentor I rely heavily on StackOverflow and whatever else Google comes up with. Should I convince my company to get an edition with an MSDN subscription? Is it one of those things where once you have it, you can't imagine life without it? What about the source control that comes with VS2010, do you all find it better than an SVN server? We're looking to hire another programmer this year, would I be best off getting a Team edition of VS2010 to be best prepared for that hire? Thanks!
