  • Scope quandary with namespaces, function templates, and static data

    - by Adrian McCarthy
    This scoping problem seems like the type of C++ quandary that Scott Meyers would have addressed in one of his Effective C++ books. I have a function, Analyze, that does some analysis on a range of data. The function is called from a few places with different types of iterators, so I have made it a template (and thus implemented it in a header file). The function depends on a static table of data, AnalysisTable, that I don't want to expose to the rest of the code. My first approach was to make the table a static const inside Analysis. namespace MyNamespace { template <typename InputIterator> int Analyze(InputIterator begin, InputIterator end) { static const int AnalysisTable[] = { /* data */ }; ... // implementation uses AnalysisTable return result; } } // namespace MyNamespace It appears that the compiler creates a copy of AnalysisTable for each instantiation of Analyze, which is wasteful of space (and, to a small degree, time). So I moved the table outside the function like this: namespace MyNamespace { const int AnalysisTable[] = { /* data */ }; template <typename InputIterator> int Analyze(InputIterator begin, InputIterator end) { ... // implementation uses AnalysisTable return result; } } // namespace MyNamespace There's only one copy of the table now, but it's exposed to the rest of the code. I'd rather keep this implementation detail hidden, so I introduced an unnamed namespace: namespace MyNamespace { namespace { // unnamed to hide AnalysisTable const int AnalysisTable[] = { /* data */ }; } // unnamed namespace template <typename InputIterator> int Analyze(InputIterator begin, InputIterator end) { ... // implementation uses AnalysisTable return result; } } // namespace MyNamespace But now I again have multiple copies of the table, because each compilation unit that includes this header file gets its own. If Analyze weren't a template, I could move all the implementation detail out of the header file. But it is a template, so I seem stuck. My next attempt was to put the table in the implementation file and to make an extern declaration within Analyze. // foo.h ------ namespace MyNamespace { template <typename InputIterator> int Analyze(InputIterator begin, InputIterator end) { extern const int AnalysisTable[]; ... // implementation uses AnalysisTable return result; } } // namespace MyNamespace // foo.cpp ------ #include "foo.h" namespace MyNamespace { const int AnalysisTable[] = { /* data */ }; } This looks like it should work, and--indeed--the compiler is satisfied. The linker, however, complains, "unresolved external symbol AnalysisTable." Drat! (Can someone explain what I'm missing here?) The only thing I could think of was to give the inner namespace a name, declare the table in the header, and provide the actual data in an implementation file: // foo.h ----- namespace MyNamespace { namespace PrivateStuff { extern const int AnalysisTable[]; } // unnamed namespace template <typename InputIterator> int Analyze(InputIterator begin, InputIterator end) { ... // implementation uses PrivateStuff::AnalysisTable return result; } } // namespace MyNamespace // foo.cpp ----- #include "foo.h" namespace MyNamespace { namespace PrivateStuff { const int AnalysisTable[] = { /* data */ }; } } Once again, I have exactly one instance of AnalysisTable (yay!), but other parts of the program can access it (boo!). The inner namespace makes it a little clearer that they shouldn't, but it's still possible. Is it possible to have one instance of the table and to move the table beyond the reach of everything but Analyze?

  • Nunit test project won't compile under mono

    - by Quandary
    Question: I am implementing an OpenSource version of Microbosoft Sync framework, [http://www.microsoft.com/downloads/d...isplaylang=en] (Checkout: git clone [email protected]:quandary/SyncFramework.git) but I ran into a unittest problem. I added a nunit test-project to the C# project, but it's not compiling... I created the project on Windows, and there it compiled well. On Linux, the project compiles well, but compiling the unittest, I always get: Assembly 'nunit.framework, Version=2.5.5.10112, Culture=neutral, PublicKeyToken=96d09 My problem now is I installed nunit and added a reference to it (on Linux with mono), but I still get this message, I take out 'require specific version', and I still get this message... I also removed the windows reference to nunit, but still no change.

  • Why deny access to website for msnbot/bingbot?

    - by Quandary
    I've seen quite a lot of tutorials that recommend you to ban user agents containing the strings libwww-perl and msnbot. I understand why one would ban libwww-perl, it's mainly if not only used for hacking and spamming. But why are there so many sites recommending to ban msnbot/bingbot? Since it's a search engine, even if only with a marginal market share, I would except one would want this bot to crawl one's sites. What is it that msnbot does that makes people ban it?

  • mono: application not running when web.config in subfolder

    - by Quandary
    I run asp.net on mono. I wanted to run blogengine: http://www.dotnetblogengine.net/ I downloaded, put it in /var/www/blogengine, on the console went to /var/www/blogengine and started xsp2. I went to http://localhost:8080, and it ran without problems. Then I stopped xsp2, went to /var/www and started xsp2. I went to http://localhost:8080/blogengine It ended with a strange error: The section <blogProvider> can't be defined in this configuration file (the allowed definition context is 'MachineToApplication'). (/var/www/blogengine/Web.Config line 9) The problem seems to be that it stops working as soon as the xsp2 root folder is anything else than the application root folder... Do I have to config anything ? Or what else is wrong ?

  • Which Linux is the most efficient?

    - by quandary
    Simple question: There is a gazillion Linux distributions out there. Which one (distribution/incl. window manager) makes (technically) the most efficient use of my (aging) computer ? I have appx. 1 GB RAM and a 1.6 GHz processor, 120 GB hd. I develop applications (C++/.NET/mono/ASP/PostGre SQL/). Usually, I prefer distros with apt-get. Anybody knows which one takes the most care of my limited RAM, and wich one is the fastest/slimmest of them all, that has a decent repo and is damn fast)

  • ASP.NET/mono performance on Linux

    - by Quandary
    Anybody knows how asp.net/mono performance is on Linux ? I mean, which server gives you the best performance/delivery time (Apache/Apache2, xsp2, lighthttp, nginx, other) ? Since all asp.net goes via xsp2, I'd say xsp2 would certainly be fastest, but it's probably missing a lot of features, which lighthttp offers (e.g. mod_dosevasive, URL-rewriting, etc.).

  • Linux: Case-INSENSITIVE Filesystem

    - by Quandary
    What methods are there to make the Linux filesystem case-INSENSITIVE ? I have asp.net applications developed on Windows, but there are always issues with capitalization/spelling on mono when putting it on Linux. One way is to mount a localhost SMB share to /var/www. Are there any others ?

  • .NET Mailserver smtp/relay problem

    - by Quandary
    Question, I'm trying to setup my own mailserver: This is the server (latest version): http://www.codeproject.com/KB/vista/SMTP_POP3_IMAP_server.aspx Now I've the following problem: I can add user accounts, and receive mails from the internet in that account. I can also setup a mailinglist. This works fine (for local users). But I can't send any emails out... Why ? I've forwarded port 25 + 110, and it works fine for receiving mails from the internet. Do I need to configure SMTP under SMTP, or under relay, or both ? Or do I miss anything ?

  • Windows 7 / 8 tool for amplifying sound / equivalent to pavucontrol?

    - by Quandary
    I'm watching live streamed videos, but the volume sometimes is barely loud enough. With Windows, I can only turn the system volume and the flash volume up to maximum, and then bad luck if that's still not loud enough. On Linux, on the same notebook, I have the same problem, but I can use pavucontrol to amplify the sound volume beyond 100%. Unfortunately, I can't always work on Linux, since Visual Studio and SQL-Server only run on Windows. Is there any tool or way to amplify volume on Windows 7 / 8 , without having to resort to run Linux in a virtual machine?

  • How to explore the local active directory ?

    - by Quandary
    Question: On Windows7, how can I explore the local active directory ? I mean getting all directory entries I would see when I execute this code: Dim AD As New System.DirectoryServices.DirectoryEntry("WinNT://" + Environment.MachineName & ",computer") I have found a systernals tool, called activedirectory explorer, (http://technet.microsoft.com/en-us/sysinternals/bb963907.aspx) and I run it as complete administrator (root), but it always says "server not working/running". But the server obviously works, since I can query it from .net... and it's definitely local, since I plugged the network connection

  • Oracle licensing /pricing ?

    - by Quandary
    Question: I'd like to download Oracle 11g database for evaluation purposes. Now I found this link for downloads: http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html But it says one must register 'for accessing premium contents'. But in the same time, it looks like one can download the full database for free. But surely, Oracle doesn't give it for free, but in the registration, there's no mention of any cost/fees, or any billing address. Is this registration free, or as 'premium' suggests, will you get a bill for it if you do (supposed you enter true data) ? Or how does Oracle handle licensing/payment ? I can not see any price tag there anywhere, nor any information on it on that registration page.

  • Test interface implementation

    - by Michael
    I have a interface in our code base that I would like to be able to mock out for unit testing. I am writing a test implementation to allow the individual tests to be able to override the specific methods they are concerned with rather than implementing every method. I've run into a quandary over how the test implementation should behave if the test fails to override a method used by the method under test. Should I return a "non-value" (0, null) in the test implementation or throw a UnsupportedOperationException to explicitly fail the test?

  • Espeak SAPI/dll usage on Windows ?

    - by Quandary
    Question: I am trying to use the espeak text-to-speech engine. So for I got it working wounderfully on linux (code below). Now I wanted to port this basic program to windows, too, but it's nearly impossible... Part of the problem is that the windows dll only allows for AUDIO_OUTPUT_SYNCHRONOUS, which means it requires a callback, but I can't figure out how to play the audio from the callback... First it crashed, then I realized, I need a callback function, now I get the data in the callback function, but I don't know how to play it... as it is neither a wav file nor plays automatically as on Linux. The sourceforge site is rather useless, because it basically says use the SAPI version, but then there is no example on how to use the sapi espeak dll...

  • ASP.NET Load unmanaged dll from bin folder

    - by Quandary
    Question: I use an embedded Firebird database in ASP.NET. Now, Firebird has a .NET wrapper around native dlls. The problem is, with the .NET compilation and execution process, the dlls get shadow copied to a temporary folder. Unfortunately, only the .NET dlls, and not the native dll. See http://msdn.microsoft.com/en-us/library/ms366723.aspx for details. Now, this makes it necessary to put the unmanaged dll somewhere into the system32 directory (or any other directory in the path environment variable). Now, I want to change the wrapper/native dll (opensource), so it loads the dll also if they are only in the bin folder. Now, my problem is, how can I, in .NET, load an unmanaged dll from an absolute path ? The absolute path is determined at runtime, not at compile-time...

  • Cannot call SAPI from dll

    - by Quandary
    Question: The below code works fine as long as it is in an executable. It uses the msft (text-to-)speech API (SAPI). But as soon as I put it in a dll and load it with loadlibrary from an executable, it doesn't work. I've also tried to change CoInitialize(NULL); to CoInitializeEx(NULL,COINIT_MULTITHREADED); and I tried with all possible flags ( COINIT_APARTMENTTHREADED, COINIT_MULTITHREADED, COINIT_DISABLE_OLE1DDE, COINIT_SPEED_OVER_MEMORY) But it's always stuck at hr = CoCreateInstance(__uuidof(SpVoice), NULL, CLSCTX_INPROC_SERVER, IID_ISpVoice, (void **) &pVoice); I also tried those flags here: CLSCTX_INPROC_SERVER,CLSCTX_SERVER, CLSCTX_ALL, but nothing seems to help... There are no errors, it doesn't crash, it just sleeps forever at CoCreateInstance... This is the code as single exe (working) #include <windows.h> #include <sapi.h> #include <iostream> #include <cstdlib> int main(int argc, char* argv[]) { ISpVoice * pVoice = NULL; //CoInitializeEx(NULL,COINIT_MULTITHREADED); HRESULT hr = CoInitialize(NULL); if( FAILED(hr) ) { MessageBox(NULL, TEXT("Failed To Initialize"), TEXT("Error"),0); printf("Failed!\n"); char buffer[2000] ; sprintf(buffer, "An error occured: 0x%08X.\n", hr); FILE * pFile = fopen ( "c:\\temp\\CoInitialize_exe.txt" , "w" ); fwrite (buffer , 1 , sizeof(buffer) , pFile ); fclose (pFile); } else { //CoGetClassObject(CLSID_SpVoice, CLSCTX_INPROC_SERVER, NULL, IID_IClassFactory, (void**) &pClsF); //hr = CoGetClassObject(CLSID_SpVoice, CLSCTX_INPROC_SERVER, NULL, IID_IClassFactory, (void**) &pClsF); hr = CoCreateInstance(__uuidof(SpVoice), NULL, CLSCTX_INPROC_SERVER, IID_ISpVoice, (void **) &pVoice); //HRESULT hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void **) &pVoice); if( SUCCEEDED( hr ) ) { hr = pVoice->Speak(L"Test Test", 0, NULL); hr = pVoice->Speak(L"This sounds normal <pitch middle = '-10'/> but the pitch drops half way through", SPF_IS_XML, NULL ); pVoice->Release(); pVoice = NULL; } else { MessageBox(NULL, TEXT("Failed To Create a COM instance..."), TEXT("Error"),0); char buffer[2000] ; sprintf(buffer, "An error occured: 0x%08X.\n", hr); FILE * pFile = fopen ( "c:\\temp\\CoCreateInstance_exe.txt" , "w" ); fwrite (buffer , 1 , sizeof(buffer) , pFile ); fclose (pFile); } } CoUninitialize(); return EXIT_SUCCESS; } This is the exe loading the dll (stays forever at printf("trying to create instance.\n"); ) #include <windows.h> #include <sapi.h> #include <iostream> #include <cstdlib> int main(int argc, char* argv[]) { // C:\Windows\System32\Speech\Common\sapi.dll //LoadLibraryA("sapi.dll"); LoadLibraryA("Sapidll2.dll"); return EXIT_SUCCESS; // Frankly, that would be nice... } And this is Sapidll2.dll // dllmain.cpp : Defines the entry point for the DLL application. #include "stdafx.h" #include <iostream> #include <cstdlib> #include <string> #include <windows.h> #include <sapi.h> int init_engine() { ISpVoice * pVoice = NULL; //HRESULT hr = CoInitializeEx(NULL, COINIT_MULTITHREADED); HRESULT hr = CoInitialize(NULL); if(FAILED(hr) ) { MessageBox(NULL, TEXT("Failed To Initialize"), TEXT("Error"), 0); char buffer[2000] ; sprintf(buffer, "An error occured: 0x%08X.\n", hr); FILE * pFile = fopen ( "c:\\temp\\CoInitialize_dll.txt" , "w" ); fwrite (buffer , 1 , strlen(buffer) , pFile ); fclose (pFile); } else { printf("trying to create instance.\n"); //HRESULT hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void **) &pVoice); //hr = CoCreateInstance(CLSID_SpVoice, NULL, CLSCTX_ALL, IID_ISpVoice, (void **) &pVoice); //HRESULT hr = CoCreateInstance(__uuidof(ISpVoice), NULL, CLSCTX_INPROC_SERVER, IID_ISpVoice, (void **) &pVoice); HRESULT hr = CoCreateInstance(__uuidof(SpVoice), NULL, CLSCTX_ALL, IID_ISpVoice, (void **) &pVoice); if( SUCCEEDED( hr ) ) { printf("Succeeded\n"); //hr = pVoice->Speak(L"The text to speech engine has been successfully initialized.", 0, NULL); } else { printf("failed\n"); MessageBox(NULL, TEXT("Failed To Create COM instance"), TEXT("Error"), 0); char buffer[2000] ; sprintf(buffer, "An error occured: 0x%08X.\n", hr); FILE * pFile = fopen ( "c:\\temp\\CoCreateInstance_dll.txt" , "w" ); fwrite (buffer , 1 , strlen(buffer) , pFile ); fclose (pFile); } } if(pVoice != NULL) { pVoice->Release(); pVoice = NULL; } CoUninitialize(); return true ; } BOOL APIENTRY DllMain( HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved) { switch (ul_reason_for_call) { case DLL_PROCESS_ATTACH: init_engine(); break; case DLL_THREAD_ATTACH: case DLL_THREAD_DETACH: case DLL_PROCESS_DETACH: break; } return TRUE; }

  • Loading a dll from a dll ?

    - by Quandary
    What's the best way for loading a dll from a dll ? My problem is I can't load a dll on process_attach, and I cannot load the dll from the main program, because I don't control the main program source. And therefore I cannot call a non-dllmain function, too.

  • How to access WebMethods in ASP.NET

    - by Quandary
    When i define an AJAX WebMethod like this in an ASPX page (ui.aspx): [System.Web.Services.WebMethod(Description = "Get Import Progress-Report")] [System.Web.Script.Services.ScriptMethod(UseHttpGet = false, ResponseFormat = System.Web.Script.Services.ResponseFormat.Json)] public static string GetProgress() { System.Web.Script.Serialization.JavaScriptSerializer JSONserializer = new System.Web.Script.Serialization.JavaScriptSerializer(); return JSONserializer.Serialize("an Object/Instance here"); } // End WebMethod-Function GetProgress Can I access the description for the corresponding service somewhere ? E.g. when I want to call the webmethod with my own JavaScript, how do I do that ? I investigated the axd files, and found the xmlhttprequest to open ui.aspx/GetProgress But when I type the address in my browser, I get redirected to ui.aspx
