  • Will a VS2008 setup project update Net 3.5 SP1?

    - by rathkopf
    I just started using the WPF WebBrowser that is included in Net 3.5 SP1. I built my setup project (which I have been using prior to moving to 3.5 SP1) and installed it on a test machine but the WebBrowser was not available. What must I do to be sure that the setup.exe/msi combination checks for and installs SP1?

  • Algorithm performance

    - by william007
    I am testing an algorithm for different parameters on a computer. I notice the performance fluctuates for each parameters. Say I run for the first time I got 20 ms, second times I got 5ms, third times I got 4ms: But the algorithm should work the same for these 3 times. I am using stopwatch from C# library to count the time, is there a better way to measure the performance without subjecting to those fluctuations?

  • deep zoom is not displayed

    - by George2
    I am using VSTS 2008 + C# + .Net 3.5 + Windows Vista Enterprise x86. I have used Silverlight Deep Zoom composer tool to export my composed images into Siverlight type. Everything is previewed fine after export successful message (I select browse from browser). But when I click the Test.html in the exported project to show Deep Zoom effects from browser, nothing is displayed. Here is my screen snapshot. Any ideas what is wrong? http://i41.tinypic.com/2dac561.jpg EDIT 1: to my surprise, there is no clientbin folder in my exported project. I have made two screen snapshots for, my project folder generated by Deep Zoom Composer under Exported Data folder; the content of GeneratedImages folder under my project folder. Please refers them to, http://i42.tinypic.com/346ncec.jpg http://i42.tinypic.com/15zqkn9.jpg Any ideas what is wrong? thanks in advance, George

  • switch easily between different main()

    - by lezebulon
    I'm using VS2010 I have a project with several headers and one file with the main() function. For testing purposes I'd like to be able to easily another main() function that would instanciate different things than my original main. Is there an easy way to define 2 "main" function, and easily switch between them? The best would be to compile 2 binaries, one that starts at main1() and the other at main2(), or it can be a solution that requires to recompile some files, it doesn't matter

  • SHGetFolderPath

    - by user530589
    This code works for windows 7 but doesn't work for windows XP (outputs only part of startup folder path) #include <iostream> #include <shlobj.h> using namespace std; int main() { wchar_t startupFolder[1024]; HRESULT hr = SHGetFolderPath(0, CSIDL_STARTUP, 0, 0, startupFolder); if (SUCCEEDED(hr)) wcout << L"Startup folder = " << startupFolder << endl; else cout << "Error when getting startup folder\n"; getchar(); return 0; } output is: Startup folder = C:\Documents and Settings\Admin\ <- cursor is here. Newline is not provided. Also I have russian window xp. I think this is unicode issue. when I use wprintf I got: C:\Documents and Settings\Admin\???????? ..... Thanks. As a temporary solution: After SHGetFolderPath I call GetShortPathName then I get path in msdos style: C:\DOCUME~1\Admin\5D29~1\4A66~1\60C2~1 Not really beautiful solution, but at least that is a valid path.

  • __declspec(dllimport) causes compiler crash on MSVC 2010

    - by Zero
    In a *.cpp file, trying to use a third party lib: #define DLL_IMPORT #include <thirdParty.h> // Third party header has code like: // #ifdef DLL_IMPORT // #define DLL_DECL __declspec(dllimport) // fatal error C1001: An internal error has occurred in the compiler. Alternative: #define NO_DLL #include <thirdParty.h> // Third party header has code like: // #elif defined(NO_DLL) // #define DLL_DECL // Compiles fine, but linker errors as can't find DLL functions // I can reproduce results by remove macros and #define all together and manually editing the third party files to have __declspec(dllimport) or not Has anyone come across anything similar, or can hint at the cause? (which is created using CMake). Above is actual example of 2 line *.cpp that crashes so it's narrowed down to something in the #include. The following also work fine: Compile the examples provided by the third party (they provide a *.sln) that use dllimport/export so it doesn't appear to be the fault of the library Compile the third party lib as part of the production project (so dllexport works fine) I've trawled the project settings pages of the two projects to try and spot differences, but have come up blank. Of course, it's possible I'm missing something as those settings pages are not the easiest to navigate. I'll get access to VS2008 in a day or so, so can compare with that. The third party library is MySql++.

  • UDP: Client started before Server

    - by Chris
    I have a bit of a glitch in my game just now, everything runs fine if the server is started before the client however when the client is started before the server they never connect. This is all UDP The problem happens when the client tries to call recvfrom() before the server has started, when this happens the client never finds the server and the server never finds the client. The resulted error is a wouldblock. If I stop the client using recvfrom and start the client before the server (the client is still sending data its just not receiving it) they both find each other no problem. Whats the solution for this? The way its seems just now is that the client cannot call recvfrom without a server being active or it all falls apart. Is there a check that can be done to see if data is sitting on a certain port(data the server would send)? Or is there a better way to do this? Some Code... Server Operation - UDPSocket is a class UDPSocket.Initialise(); UDPSocket.MakeNonBlocking(); UDPSocket.Bind(LOCALPORT); int n = UDPSocket.Receive(&thePacket); if (n > 0) UDPSocket.Send(&sendPacket); Client... UDP.Initialise(); UDP.MakeNonBlocking(); UDP.SetDestinationAddress(SERVERIP, SERVERPORT); serverStatus = UDP.Receive(&recvPacket); if (serverStatus > 0) { //Do some things UDP.Send(dPacket); //Try and reconnect with server } Thanks

  • vcxproj file won't load into solution.

    - by John C
    We've just recently switched to VS 2010 and i had a solution that was working fine. This moring when i try to load the solution i get the error: "An item with the same key has already been added." This occurs when it is trying to load one of our main projects and it is not loaded. I assumed the problem was with my solution so i created a brand new empty solution and tried to load the same vcxproj and got exactly the same error. When i revert the project file to a previous version it works, so apparently it's something in the vcxproj file. However it also appears that i'm the only one in the office that is affected. So some combination of the vcxproj file and my computer seems to be the issue. Has anyone seen anything like this before? Any ideas on a solution? Thanks

  • I get `System.Web.UI.WebControls.TextBox` instead of TextBox value

    - by Anna T
    Gooday. Could you help me figure out please why I get this: System.Web.UI.WebControls.TextBox on Label1: DataListItem item = DataList1.Items[0]; TextBox nume = (TextBox)item.FindControl("numeTb"); Label1.Text = nume.ToString(); I specify that the numeTb element is put like this in the ASPX file: <asp:TextBox ID="numeTb" runat="server" Width="400px" Text='<%# Eval("nume") %>' DataTextField="nume" DataValueField="nume"></asp:TextBox> I just added the DataTextField bits thinking might help, but no. Thank you!

  • Why does C++ linking use virtually no CPU? (updated)

    - by John
    On a native C++ project, linking right now can take a minute or two, yet during this time CPU drops from 100% during compilation to virtually zero. Does this mean linking is primarily a disk activity? If so, is this the main area an SSD would make big changes? But, why aren't all my OBJ files (or as many as possible) kept in RAM after compilation to avoid this? With 4Gb of RAM I should be able to save a lot of disk access and make it CPU-bound again, no? update: so the obvious follow-up is, can VC++ compiler and linker talk together better to streamline things and keep OBJ files in memory, similar to how Delphi does?

  • Passing User Data with SetTimer

    - by GJ
    I am calling SetTimer in a function of a Class. SetTimer(NULL, 0, 10000, (TIMERPROC) TimerCallBack); Where TimerCallBack is: static VOID CALLBACK TimerCallBack(HWND, UINT, UINT, DWORD) Now my need is to call one of the method of class which initiated timer, since TimerCallBack is static it has no access to the class object anymore. I cant find any way to pass object pointer along with the SetTimer so that I can receive it back on Callback function. Is there any other way to achieve this, if its not supported using SetTimer then which other way I can implement this.

  • C#: How to unit test a method that relies on another method within the same class?

    - by michael paul
    I have a class similar to the following: public class MyProxy : ClientBase<IService>, IService { public MyProxy(String endpointConfiguration) : base(endpointConfiguration) { } public int DoSomething(int x) { int result = DoSomethingToX(x); //This passes unit testing int result2 = ((IService)this).DoWork(x) //do I have to extract this part into a separate method just //to test it even though it's only a couple of lines? //Do something on result2 int result3 = result2 ... return result3; } int IService.DoWork(int x) { return base.Channel.DoWork(x); } } The problem lies in the fact that when testing I don't know how to mock the result2 item without extracting the part that gets result3 using result2 into a separate method. And, because it is unit testing I don't want to go that deep as to test what result2 comes back as... I'd rather mock the data somehow... like, be able to call the function and replace just that one call.

  • Localizing formatting functions instead of properties in VS.NET resources

    - by LexL
    I noticed that .NET framework uses formatting functions, generated the same way localizable string are. There is a resource file Resources.resx with resource string TestString. So you may use it in code like this: string localizableValue = Resources.TestString; Now, imagine you need a formattable localizable string, to use it in string.Format function. So everytime you use it, you have to write something like this: string localizableFormattedValue = string.Format(Resources.TestFormatString, someParam1, someParam2); The observation says that in .NET framework generated resource classes already include the above construction. So instead of string property, a string function is generated. The resulting code looks like this: string localizableFormattedValue = Resources.TestFormatString(someParam1, someParam2); The question is - how do they do this? Is it some custom Microsoft feature (resx generator) or I'm missing something obvious?
