DBWIN32 is my creation +to solve this problem. + +The code is essentially a merging of a stripped down version of the DBWIN code +from VC 1.5 and DBMON.C with a few 32 bit changes. + +As of version 1.2B, DBWIN32 supports both Win95 and NT. The NT support is +built into the operating system and works just by running DBWIN32. The Win95 +team decided not to support this hook, so I have provided code that will do +this for you. See the file WIN95.TXT for instructions on installing this. + +If you have questions, problems or suggestions about DBWIN32, I welcome your +feedback and plan to actively maintain the code. + +Andrew Tucker +ast@halcyon.com + +To download dbwin32, see e.g.: + +http://ftp.digital.com/pub/micro/NT/WinSite/programr/dbwin32.zip +*/ + +#if !defined(__MWERKS__) && !defined(__SALFORDC__) && !defined(__TWIN32__) +#include +#endif + +void OutputDebugStringW95(const char* lpOutputString, ...) +{ + HANDLE heventDBWIN; /* DBWIN32 synchronization object */ + HANDLE heventData; /* data passing synch object */ + HANDLE hSharedFile; /* memory mapped file shared data */ + LPSTR lpszSharedMem; + char achBuffer[500]; + + /* create the output buffer */ + va_list args; + va_start(args, lpOutputString); + vsprintf(achBuffer, lpOutputString, args); + va_end(args); + + /* + Do a regular OutputDebugString so that the output is + still seen in the debugger window if it exists. + + This ifdef is necessary to avoid infinite recursion + from the inclusion of W95TRACE.H + */ +#ifdef _UNICODE + ::OutputDebugStringW(achBuffer); +#else +#ifdef __TWIN32__ + ::OutputDebugString(achBuffer); +#else + ::OutputDebugStringA(achBuffer); +#endif +#endif + + /* bail if it's not Win95 */ + { + OSVERSIONINFO VerInfo; + VerInfo.dwOSVersionInfoSize = sizeof(OSVERSIONINFO); + GetVersionEx(&VerInfo); + if ( VerInfo.dwPlatformId != VER_PLATFORM_WIN32_WINDOWS ) + return; + } + + /* make sure DBWIN is open and waiting */ + heventDBWIN = OpenEvent(EVENT_MODIFY_STATE, FALSE, "DBWIN_BUFFER_READY"); + if ( !heventDBWIN ) + { + //MessageBox(NULL, "DBWIN_BUFFER_READY nonexistent", NULL, MB_OK); + return; + } + + /* get a handle to the data synch object */ + heventData = OpenEvent(EVENT_MODIFY_STATE, FALSE, "DBWIN_DATA_READY"); + if ( !heventData ) + { + // MessageBox(NULL, "DBWIN_DATA_READY nonexistent", NULL, MB_OK); + CloseHandle(heventDBWIN); + return; + } + + hSharedFile = CreateFileMapping((HANDLE)-1, NULL, PAGE_READWRITE, 0, 4096, "DBWIN_BUFFER"); + if (!hSharedFile) + { + //MessageBox(NULL, "DebugTrace: Unable to create file mapping object DBWIN_BUFFER", "Error", MB_OK); + CloseHandle(heventDBWIN); + CloseHandle(heventData); + return; + } + + lpszSharedMem = (LPSTR)MapViewOfFile(hSharedFile, FILE_MAP_WRITE, 0, 0, 512); + if (!lpszSharedMem) + { + //MessageBox(NULL, "DebugTrace: Unable to map shared memory", "Error", MB_OK); + CloseHandle(heventDBWIN); + CloseHandle(heventData); + return; + } + + /* wait for buffer event */ + WaitForSingleObject(heventDBWIN, INFINITE); + + /* write it to the shared memory */ +#if defined( __BORLANDC__ ) || defined( __MWERKS__ ) || defined(__SALFORDC__) + *((LPDWORD)lpszSharedMem) = getpid(); +#else + *((LPDWORD)lpszSharedMem) = _getpid(); +#endif + + wsprintf(lpszSharedMem + sizeof(DWORD), "%s", achBuffer); + + /* signal data ready event */ + SetEvent(heventData); + + /* clean up handles */ + CloseHandle(hSharedFile); + CloseHandle(heventData); + CloseHandle(heventDBWIN); + + return; } + +#endif + + +#ifdef wxUSE_VC_CRTDBG + +// maximum mumber of lines the output console should have +static const WORD MAX_CONSOLE_LINES = 500; + +BOOL WINAPI MyConsoleHandler( DWORD dwCtrlType ) { // control signal type + FreeConsole(); + return TRUE; +} + +void wxRedirectIOToConsole() +{ + int hConHandle; + long lStdHandle; + CONSOLE_SCREEN_BUFFER_INFO coninfo; + FILE *fp; + + // allocate a console for this app + AllocConsole(); + + // set the screen buffer to be big enough to let us scroll text + GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), + &coninfo); + coninfo.dwSize.Y = MAX_CONSOLE_LINES; + SetConsoleScreenBufferSize(GetStdHandle(STD_OUTPUT_HANDLE), + coninfo.dwSize); + + // redirect unbuffered STDOUT to the console + lStdHandle = (long)GetStdHandle(STD_OUTPUT_HANDLE); + hConHandle = _open_osfhandle(lStdHandle, _O_TEXT); + if(hConHandle <= 0) return; + fp = _fdopen( hConHandle, "w" ); + *stdout = *fp; + setvbuf( stdout, NULL, _IONBF, 0 ); + + // redirect unbuffered STDIN to the console + lStdHandle = (long)GetStdHandle(STD_INPUT_HANDLE); + hConHandle = _open_osfhandle(lStdHandle, _O_TEXT); + if(hConHandle <= 0) return; + fp = _fdopen( hConHandle, "r" ); + *stdin = *fp; + setvbuf( stdin, NULL, _IONBF, 0 ); + + // redirect unbuffered STDERR to the console + lStdHandle = (long)GetStdHandle(STD_ERROR_HANDLE); + hConHandle = _open_osfhandle(lStdHandle, _O_TEXT); + if(hConHandle <= 0) return; + fp = _fdopen( hConHandle, "w" ); + *stderr = *fp; + setvbuf( stderr, NULL, _IONBF, 0 ); + + // make cout, wcout, cin, wcin, wcerr, cerr, wclog and clog + // point to console as well + ios::sync_with_stdio(); + + SetConsoleCtrlHandler(MyConsoleHandler, TRUE); + +} +#else +// Not supported +void wxRedirectIOToConsole() +{ +} +#endif + +
