  • IdHTTP XML, getting xml, help please

    - by user1748535
    Already some day I can not solve the problem. Help than you can. I'm using Delphi 2010, and I can not get through IdHTTP XML document from the site. I always had the answer 403 / HTTP 1.1 and text/html (need text/xml) When using MSXML all well and getting XML file. But I need a proxy, so need idhtop. When using the synapse does not change. Work with msxml: CoInitialize(nil); GetXML:={$IFDEF VER210}CoXMLHTTP{$ELSE}CoXMLHTTPRequest{$ENDIF}.Create; GetXML.open('POST', '***************', false, EmptyParam, EmptyParam); GetXML.setRequestHeader('Host', '***************'); GetXML.setRequestHeader('User-Agent', 'Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13'); GetXML.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); GamesBody:='***************'; GetXML.send(GamesBody); Form1.Memo2.Lines.Text:=GetXML.responseText; ResultPage:=GetXML.responseText; if Pos('error code', ResultPage)=0 then begin CoUninitialize; how to set up IdHTTP? All settings have changed 100 times Or a connection to a proxy MSXML?

  • How to create a console application that does not terminate?

    - by John
    Hello, In C++,a console application can have a message handler in its Winmain procedure.Like this: int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { HWND hwnd; MSG msg; #ifdef _DEBUG CreateConsole("Title"); #endif hwnd = CreateDialog(hInstance, MAKEINTRESOURCE(IDD_DIALOG1), NULL, DlgProc); PeekMessage(&msg, NULL, 0, 0, PM_NOREMOVE); while(msg.message != WM_QUIT) { if(PeekMessage(&msg, NULL, 0, 0, PM_REMOVE)) { if(IsDialogMessage(hwnd, &msg)) continue; TranslateMessage(&msg); DispatchMessage(&msg); } } return 0; } This makes the process not close until the console window has received WM_QUIT message. I don't know how to do something similar in delphi. My need is not for exactly a message handler, but a lightweight "trick" to make the console application work like a GUI application using threads. So that, for example, two Indy TCP servers could be handled without the console application terminating the process. My question: How could this be accomplished?

  • Mac OS X linker error in Qt; CoreGraphics & CGWindowListCreate

    Here is my .mm file #include "windowmanagerutils.h" #ifdef Q_OS_MAC #import </System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics.framework/Headers/CGWindow.h> QRect WindowManagerUtils::getWindowRect(WId windowId) { CFArrayRef windows = CGWindowListCreate(kCGWindowListOptionOnScreenOnly, kCGNullWindowID); return QRect(); } QRect WindowManagerUtils::getClientRect(WId windowId) { return QRect(); } QString WindowManagerUtils::getWindowText(WId windowId) { return QString(); } WId WindowManagerUtils::rootWindow() { QApplication::desktop()->winId(); } WId WindowManagerUtils::windowFromPoint(const QPoint &p, WId parent, bool(*filterFunction)(WId)) { return NULL; } void WindowManagerUtils::setTopMostCarbon(const QWidget *const window, bool topMost) { if (!window) { return; } // Find a Cocoa equivalent for this Carbon function // [DllImport("/System/Library/Frameworks/Carbon.framework/Versions/Current/Carbon")] // OSStatus ret = HIViewSetZOrder(this->winId(), kHIViewZOrderAbove, NULL); } #endif The linker is telling me "_CGWindowListCreate" is undefined. What libraries must I link to? Apple's documentation is not very helpful on telling what to include or link to, like MSDN is. Also I couldn't just do #import <CGWindow.h>, I had to specify the absolute path to it... any way around that?

  • Writing fortran robust and "modern" code

    - by Blklight
    In some scientific environments, you often cannot go without FORTRAN as most of the developers only know that idiom, and there is lot of legacy code and related experience. And frankly, there are not many other cross-platform options for high performance programming ( C++ would do the task, but the syntax, zero-starting arrays, and pointers are too much for most engineers ;-) ). I'm a C++ guy but I'm stuck with some F90 projects. So, let's assume a new project must use FORTRAN (F90), but I want to build the most modern software architecture out of it. while being compatible with most "recent" compilers (intel ifort, but also including sun/HP/IBM own compilers) So I'm thinking of imposing: global variable forbidden, no gotos, no jump labels, "implicit none", etc. "object-oriented programming" (modules with datatypes + related subroutines) modular/reusable functions, well documented, reusable libraries assertions/preconditions/invariants (implemented using preprocessor statements) unit tests for all (most) subroutines and "objects" an intense "debug mode" (#ifdef DEBUG) with more checks and all possible Intel compiler checks possible (array bounds, subroutine interfaces, etc.) uniform and enforced legible coding style, using code processing tools C stubs/wrappers for libpthread, libDL (and eventually GPU kernels, etc.) C/C++ implementation of utility functions (strings, file operations, sockets, memory alloc/dealloc reference counting for debug mode, etc.) ( This may all seem "evident" modern programming assumptions, but in a legacy fortran world, most of these are big changes in the typical programmer workflow ) The goal with all that is to have trustworthy, maintainable and modular code. Whereas, in typical fortran, modularity is often not a primary goal, and code is trustworthy only if the original developer was very clever, and the code was not changed since then ! (i'm a bit joking here, but not much) I searched around for references about object-oriented fortran, programming-by-contract (assertions/preconditions/etc.), and found only ugly and outdated documents, syntaxes and papers done by people with no large-scale project involvement, and dead projects. Any good URL, advice, reference paper/books on the subject?

  • Receiving client-event on a GtkWindow

    - by fret
    I'm trying to send and receive a client-event using a GtkWindow on the win32 platform. The sending code looks like this: GtkWidget *Wnd; GdkNativeWindow Hnd = #ifdef WIN32 GDK_WINDOW_HWND(Wnd->window); #else GDK_WINDOW_XWINDOW(Wnd->window); #endif GdkEvent *Event = gdk_event_new(GDK_CLIENT_EVENT); // fill out Event params gdk_event_send_client_message(Event, Hnd); Receiving code looks like this: static gboolean MyClientEvent(GtkWidget *widget, GdkEventClient *ev, MyWnd *Wnd) { // breakpoint here... return TRUE; } GtkWidget *Wnd = gtk_window_new(GTK_WINDOW_TOPLEVEL); g_signal_connect( G_OBJECT(Wnd), "client-event", G_CALLBACK(MyClientEvent), this); gtk_widget_add_events(Wnd, GDK_ALL_EVENTS_MASK); I used Spy++ to see the message getting sent, so I know the sending side is ok. The receiving side however doesn't get the client-event. I was expecting my breakpoint in the callback to trigger... but it doesn't. I'm not even sure if a GtkWindow can receive a client-event... from past experience on X11 I thought it was pretty much the same as any other GtkWidget in that respect. Maybe on the win32 platform it's kinda different. But still I'd like to be able to get this working.

  • Dll Import : Unable to find Entry Point "fnMultiply" in DLL "ImportDLL"

    - by user662285
    I am trying to use DLLImport for using Win32 dll method in C#. Win32 dll C++ // .h file #ifdef IMPORTDLL_EXPORTS #define IMPORTDLL_API __declspec(dllexport) #else #define IMPORTDLL_API __declspec(dllimport) #endif // This class is exported from the ImportDLL.dll class IMPORTDLL_API CImportDLL { public: CImportDLL(void); // TODO: add your methods here. int Add(int a , int b); }; extern IMPORTDLL_API int nImportDLL; IMPORTDLL_API int fnImportDLL(void); IMPORTDLL_API int fnMultiply(int a,int b); // .cpp file // ImportDLL.cpp : Defines the exported functions for the DLL application. // #include "stdafx.h" #include "ImportDLL.h" // This is an example of an exported variable IMPORTDLL_API int nImportDLL=0; // This is an example of an exported function. IMPORTDLL_API int fnImportDLL(void) { return 42; } IMPORTDLL_API int fnMultiply(int a , int b) { return (a*b); } Once i build this i get ImportDLL.dll Now i create Windows Application and add this dll in debug folder and try to use this method using DLLImport [DllImport("ImportDLL.dll")] public static extern int fnMultiply(int a, int b); And I try to call this in C# int a = fnMultiply(5, 6); // This line gives error Unable to find an entry point Can any body tell what i am missing?

  • Very weird C file-handling anomaly

    - by KáGé
    Hello, I got a very weird issue that I cant figure out in my school project, which is the simulation of a simple filesystem in a human-readable textfile. Unfortunately I don't yet have enough time to translate the comments in my code or make it less gibberish, so if you are bothered by that, you don't have to help, I understand. See the code HERE. Now in drive.h, at line 574 is this part: i = getline(); #ifdef DEBUG printf("Free space in all found at %d.\n\n", i); if(drive.disk != NULL){ printf("Disk OK\n\n"); } #endif //write in data state = seekline(i); Before this it finds place for the allocation database entry in the ALL sector (see the "image files" in the mounts folder, this issue was tested on mount_30.efs-dbf), then gets the line with i = getline() fine (getline is in lglobal.h, line 39), but after that any file manipulation (in this case seekline's fseek, but if I comment that out, then the first fprintf after that) crashes the program straight away. I think the file gets somehow corrupted (though the Disk OK message appears) but can't figure out how. I've tried putting i = getline(); into comment, but it didn't make any difference. I've also tried asking at local programming forums but they didn't really help either. The last few lines of the output before it crashes: Dir written. (drive.h line 562) Seekline entered: 268 (called at drive.h line 564) Getline entered. (called at drive.h line 574) Line got: 268. Free space in all found at 268. (drive.h line 576) Seekline entered: 268 (called at drive.h line 582, note that this exact call was run successfully less than 20 lines back. This one should set the pointer to the beginning of the line it is currently in) After this it crashes. Does anyone has any idea of what causes this and how could I fix it? Thank you.

  • Atomic swap in GNU C++

    - by Steve
    I want to verify that my understanding is correct. This kind of thing is tricky so I'm almost sure I am missing something. I have a program consisting of a real-time thread and a non-real-time thread. I want the non-RT thread to be able to swap a pointer to memory that is used by the RT thread. From the docs, my understanding is that this can be accomplished in g++ with: // global Data *rt_data; Data *swap_data(Data *new_data) { #ifdef __GNUC__ // Atomic pointer swap. Data *old_d = __sync_lock_test_and_set(&rt_data, new_data); #else // Non-atomic, cross your fingers. Data *old_d = rt_data; rt_data = new_data; #endif return old_d; } This is the only place in the program (other than initial setup) where rt_data is modified. When rt_data is used in the real-time context, it is copied to a local pointer. For old_d, later on when it is sure that the old memory is not used, it will be freed in the non-RT thread. Is this correct? Do I need volatile anywhere? Are there other synchronization primitives I should be calling? By the way I am doing this in C++, although I'm interested in whether the answer differs for C. Thanks ahead of time.

  • Problem with setjmp/longjmp

    - by user294732
    The code below is just not working. Can anybody point out why #define STACK_SIZE 1524 static void mt_allocate_stack(struct thread_struct *mythrd) { unsigned int sp = 0; void *stck; stck = (void *)malloc(STACK_SIZE); sp = (unsigned int)&((stck)); sp = sp + STACK_SIZE; while((sp % 8) != 0) sp--; #ifdef linux (mythrd->saved_state[0]).__jmpbuf[JB_BP] = (int)sp; (mythrd->saved_state[0]).__jmpbuf[JB_SP] = (int)sp-500; #endif } void mt_sched() { fprintf(stdout,"\n Inside the mt_sched"); fflush(stdout); if ( current_thread->state == NEW ) { if ( setjmp(current_thread->saved_state) == 0 ) { mt_allocate_stack(current_thread); fprintf(stdout,"\n Jumping to thread = %u",current_thread->thread_id); fflush(stdout); longjmp(current_thread->saved_state, 2); } else { new_fns(); } } } All I am trying to do is to run the new_fns() on a new stack. But is is showing segmentation fault at new_fns(). Can anybody point me out what's wrong.

  • Setting the default stack size on Linux globally for the program

    - by wowus
    So I've noticed that the default stack size for threads on linux is 8MB (if I'm wrong, PLEASE correct me), and, incidentally, 1MB on Windows. This is quite bad for my application, as on a 4-core processor that means 64 MB is space is used JUST for threads! The worst part is, I'm never using more than 100kb of stack per thread (I abuse the heap a LOT ;)). My solution right now is to limit the stack size of threads. However, I have no idea how to do this portably. Just for context, I'm using Boost.Thread for my threading needs. I'm okay with a little bit of #ifdef hell, but I'd like to know how to do it easily first. Basically, I want something like this (where windows_* is linked on windows builds, and posix_* is linked under linux builds) // windows_stack_limiter.c int limit_stack_size() { // Windows impl. return 0; } // posix_stack_limiter.c int limit_stack_size() { // Linux impl. return 0; } // stack_limiter.cpp int limit_stack_size(); static volatile int placeholder = limit_stack_size(); How do I flesh out those functions? Or, alternatively, am I just doing this entirely wrong? Remember I have no control over the actual thread creation (no new params to CreateThread on Windows), as I'm using Boost.Thread.

  • How do I send a client-event asynchronously to a GtkWidget?

    - by fret
    I'm trying to send and receive a client-event using a GtkWidget on the win32 platform. The sending code looks like this: GtkWidget *Wnd; GdkNativeWindow Hnd = #ifdef WIN32 GDK_WINDOW_HWND(Wnd->window); #else GDK_WINDOW_XWINDOW(Wnd->window); #endif GdkEvent *Event = gdk_event_new(GDK_CLIENT_EVENT); // fill out Event params gdk_event_send_client_message(Event, Hnd); Receiving code looks like this: static gboolean MyClientEvent(GtkWidget *widget, GdkEventClient *ev, MyWnd *Wnd) { // breakpoint here... return TRUE; } GtkWidget *Wnd = gtk_window_new(GTK_WINDOW_TOPLEVEL); g_signal_connect( G_OBJECT(Wnd), "client-event", G_CALLBACK(MyClientEvent), this); gtk_widget_add_events(Wnd, GDK_ALL_EVENTS_MASK); I used Spy++ to see the message getting sent, so I know the sending side is ok. The receiving side however doesn't get the client-event. I was expecting my breakpoint in the callback to trigger... but it doesn't. I'm not even sure if a GtkWindow can receive a client-event... from past experience on X11 I thought it was pretty much the same as any other GtkWidget in that respect. Maybe on the win32 platform it's kinda different. But still I'd like to be able to get this working. I would like this to work with asynchronously, and in a thread-safe fashion, so that I can send events from worker threads up to the GUI thread.

  • Do I have to bind an UDP socket in my client program, to receive data? (I always get WASEINVAL)...

  • ParseKit.framework won't work, Foundation.h not found

    - by Jeremy
    I'm really stumped trying to get the ParseKit.framework (this) to work in general, not even bothering to implement it till it runs the demo app that comes with it. What happens is the compiler can't locate < Foundation/Foundation.h or something, which I thought the header was in the linked framework. Exact error: "Lexical or Preprocessor Issue: 'Foundation/Foundation.h' file not found." Here's the code, just from the ParseKit_Prefix.pch: // // Prefix header for all source files of the 'ParseKit' target in the 'ParseKit' project. //#ifdef __OBJC__ #import <Foundation/Foundation.h> #endif Nothing unusual about it, did I mess up the file paths some how? I've reinstalled Xcode, re-downloaded the ParseKit, and nothing is helping. The suggestions here did nothing and it's not this. When I make a new project or use a different project and load the Foundation.framework and #import the header it works just fine. If I unlink the framework I can't find it to re-link again. Has anyone else had this kind of problem? Did I download it wrong somewhere? I have a very difficult time finding where exactly the Xcode UI links stuff, apple must get a kick out of frustrating people, so if anyone has anything they can think of please give me some feedback, I'm horribly confused right now. Thanks,

  • Java conditional compilation: how to prevent code chunks to be compiled?

    - by khachik
    My project requires Java 1.6 for compilation and running. Now I have a requirement to make it working with Java 1.5 (from the marketing side). I want to replace method body (return type and arguments remain the same) to make it compiling with Java 1.5 without errors. Details: I have an utility class called OS which encapsulates all OS-specific things. It has a method public static void openFile(java.io.File file) throws java.io.IOException { // open the file using java.awt.Desktop ... } to open files like with double-click (start Windows command or open Mac OS X command equivalent). Since it cannot be compiled with Java 1.5, I want to exclude it during compilation and replace by another method which calls run32dll for Windows or open for Mac OS X using Runtime.exec. Question: How can I do that? Can annotations help here? Note: I use ant, and I can make two java files OS4J5.java and OS4J6.java which will contain the OS class with the desired code for Java 1.5 and 1.6 and copy one of them to OS.java before compiling (or an ugly way - replace the content of OS.java conditionally depending on java version) but I don't want to do that, if there is another way. Elaborating more: in C I could use ifdef, ifndef, in Python there is no compilation and I could check a feature using hasattr or something else, in Common Lisp I could use #+feature. Is there something similar for Java? Found this post but it doesn't seem to be helpful. Any help is greatly appreciated. kh.

  • GNU C++ how to check when -std=c++0x is in effect?

    - by TerryP
    My system compiler (gcc42) works fine with the TR1 features that I want, but trying to support newer compiler versions other than the systems, trying to accessing TR1 headers an #error demanding the -std=c++0x option because of how it interfaces with library or some hub bub like that. /usr/local/lib/gcc45/include/c++/bits/c++0x_warning.h:31:2: error: #error This file requires compiler and library support for the upcoming ISO C++ standard, C++0x. This support is currently experimental, and must be enabled with the -std=c++0x or -std=gnu++0x compiler options. Having to supply an extra switch is no problem, to support GCC 4.4 and 4.5 under this system (FreeBSD), but obviously it changes the picture! Using my system compiler (g++ 4.2 default dialect): #include <tr1/foo> using std::tr1::foo; Using newer (4.5) versions of the compiler with -std=c++0x: #include <foo> using std::foo; Is there anyway using the pre processor, that I can tell if g++ is running with C++0x features enabled? Something like this is what I'm looking for: #ifdef __CXX0X_MODE__ #endif but I have not found anything in the manual or off the web. At this rate, I'm starting to think that life would just be easier, to use Boost as a dependency, and not worry about a new language standard arriving before TR4... hehe.

  • Determine whether app is communicating with APNS sandbox or production environment

    - by goldierox
    I have push notifications set up in my app. I'm trying to determine whether the device token I've received from APNS in the application:didRegisterForRemoteNotificationsWithDeviceToken: method came from the sandbox or development environment. If I can distinguish which environment initialized the token, I'll be able to tell my server to which environment to send the push notification. I've tried using the DEBUG macro to determine this, but I've seen some strange behavior with this and don't trust it to be 100% correct. #ifdef DEBUG BOOL isProd = YES; #else BOOL isProd = NO; #endif Ideally, I'd be able to examine the aps-environment entitlement (value is Development or Production) in code, but I'm not sure if this is even possible. What's the proper way to determine whether your app is communicating with the APNS sandbox or production environments? I'm assuming that the server needs to know this in the first place. Please correct me if this is assumption is incorrect. Edited: Apple's documentation on Provider Communication with APNS details the difference between communicating with the sandbox and production. However, the documentation doesn't give information on how to be consistent with registering the token (from the iOS client app) and communicating with the server.

  • C header file won't compile with C, but will with C++.

    - by Leif Andersen
    I have the following chunk of a header file BKE_mesh.h: /* Connectivity data */ typedef struct IndexNode { struct IndexNode *next, *prev; int index; } IndexNode; void create_vert_face_map(ListBase **map, IndexNode **mem, const struct MFace *mface, const int totvert, const int totface); void create_vert_edge_map(ListBase **map, IndexNode **mem, const struct MEdge *medge, const int totvert, const int totedge); Note that the header file was prepared for the possibility of being used in a C++ file, as it had: #ifdef __cplusplus extern "C" { #endif at the top of the file, and the needed finish at the bottom. But the class implementing it was written in C. Next, whenever I try to #include the header file, I get an odd error. If the file has a .cpp extension, it compiles just fine, no complaints whatsoever. However, if I do: #include "BKE_mesh.h" inside of a file with a .c extension, I get the following errors: expected ')' before '*' token for the two last functions, in specific, the variable: ListBase **map in both classes. (Note that earlier in the header file, it declared, but not defined ListBase). So, my question is: why is this valid C++ code, but not C code? Thank you.

  • Unicode version of base64 encoding/ decoding

    - by Yan Cheng CHEOK
    I am using base64 encoding/decoding from http://www.adp-gmbh.ch/cpp/common/base64.html It works pretty well with the following code. const std::string s = "I Am A Big Fat Cat" ; std::string encoded = base64_encode(reinterpret_cast<const unsigned char*>(s.c_str()), s.length()); std::string decoded = base64_decode(encoded); std::cout << _T("encoded: ") << encoded << std::endl; std::cout << _T("decoded: ") << decoded << std::endl; However, when comes to unicode namespace std { #ifdef _UNICODE typedef wstring tstring; #else typedef string tstring; #endif } const std::tstring s = _T("I Am A Big Fat Cat"); How can I still make use of the above function? Merely changing std::string base64_encode(unsigned TCHAR const* , unsigned int len); std::tstring base64_decode(std::string const& s); will not work correctly. (I expect base64_encode to return ASCII. Hence, std::string should be used instead of std::tstring)

    I am new bee to swig. I have a third party c++ dll with the following functions export. I want to call these dll functions in python. So thought of using swig to generate the wrapper using swig. I am not sure what sort of wrapper i need to generate (do i need to generate .lib or .dll to use it in python?). In case i need to generate .dll how do i do that using visual studio 2010. There are some call back function like SetNotifyHandler(void (__stdcall * nf)(int wp, void *lp)) in the bellow list. How do define such function in interface file. can someone help me plese? enter code here #ifndef DLL_H #define DLL_H #ifdef DLL_BUILD #define DLLFUNC __declspec(dllexport) #else #define DLLFUNC __declspec(dllimport) #endif #pragma pack(push) #pragma pack(1) #pragma pack(pop) extern "C" { DLLFUNC int __stdcall StartServer(void); DLLFUNC int __stdcall GetConnectionInfo(int connIndex, Info *buf); DLLFUNC void __stdcall SetNotifyWindow(HWND nw); DLLFUNC void __stdcall SetNotifyHandler(void (__stdcall * nf)(int wp, void *lp)); DLLFUNC int __stdcall SendCommand(int connIndex, Command *cmd); };

  • Portable way of counting milliseconds in C++ ?

    - by ereOn
    Hi, Is there any portable (Windows & Linux) way of counting how many milliseconds elapsed between two calls ? Basically, I want to achieve the same functionnality than the StopWatch class of .NET. (for those who already used it) In a perfect world, I would have used boost::date_time but that's not an option here due to some silly rules I'm enforced to respect. For those who better read code, this is what I'd like to achieve. Timer timer; timer.start(); // Some instructions here timer.stop(); // Print out the elapsed time std::cout << "Elapsed time: " << timer.milliseconds() << "ms" << std::endl; So, if there is a portable (set of) function(s) that can help me implement the Timer class, what is it ? If there is no such function, what Windows & Linux API should I use to achieve this functionnality ? (using #ifdef WINDOWS-like macros) Thanks !

  • __declspec(dllimport) causes compiler crash on MSVC 2010

    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++.
