Winedbg: Open Xterm when Controlling console no more available
by Uwe Bonnes Jan. 14, 2003

Jan. 14, 2003

Hallo Eric, another winedbg feature request: When the starting application spawns off other processes and exec itself, with the other spawned processes still running, and one of these processes crashes, and winedbg is configured to work on the starting console, winedbg starts, loads all dll, but then exits immediate due to the missing console. In this situation, winedbg should test if console access is still possible, and when not, it should start magically an xterm. I still prefer to use the console for winedbg interaction, as scrolling is easier.

Re: Bug Fix With Delay load function in Shell32

Hi! This isn't the best solution since GetShellOle() initializes the ole subsystem by calling OleInitialize(). This is not nessesary for _CoCreateInstance().

Wine and Windows error code
by mpfbk＠free.fr Jan. 14, 2003

Jan. 14, 2003

Tests of win32 API returned error codes inside Wine This subject has maybe been treated before, sorry if it has already been discussed and closed. Running the following simple and standard program, nothing special happens: the windows opens itself, it can be closed with the close button, and the message box is displayed when the left mouse button is pressed inside the window. /* * testbed1_ref.c * */ #define STRICT #include <windows.h> const char g_szClassName[] = "testbed1WindowClass"; /* ============================================================ */ static void ErrorBox(LPCSTR msg) { LPVOID error_msg; DWORD error_code; char error_buffer[256]; error_code = GetLastError(); FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM, NULL, error_code, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR) &error_msg, 0, NULL ); /* TBC: should be snprintf */ sprintf(error_buffer, "%s: %d:%s", msg, error_code, error_msg); MessageBox(NULL, error_buffer, "Error!", MB_ICONEXCLAMATION | MB_OK); LocalFree( error_msg ); } /* ============================================================ */ LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) { switch(msg) { case WM_LBUTTONDOWN: { char szFileName[MAX_PATH]; HINSTANCE hInstance; if(IsDebuggerPresent()) { MessageBox(NULL, "Running under debugger control", "Debug!", MB_ICONINFORMATION | MB_OK); } else { OutputDebugString(TEXT("No debugger, but 'OutputDebugString' works, since you see this (in DBWin32 for instance)")); } hInstance = GetModuleHandle(NULL); GetModuleFileName(hInstance, szFileName, MAX_PATH); MessageBox(hwnd, szFileName, "This program is:", MB_OK | MB_ICONINFORMATION); } break; case WM_CLOSE: DestroyWindow(hwnd); break; case WM_DESTROY: PostQuitMessage(0); break; default: return DefWindowProc(hwnd, msg, wParam, lParam); } return 0; } /* ============================================================ */ int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { WNDCLASSEX wc; HWND hwnd; MSG Msg; /* Register the Window Class */ wc.cbSize = sizeof(WNDCLASSEX); wc.style = 0; wc.lpfnWndProc = WndProc; wc.cbClsExtra = 0; wc.cbWndExtra = 0; wc.hInstance = hInstance; wc.hIcon = LoadIcon(NULL, IDI_APPLICATION); wc.hCursor = LoadCursor(NULL, IDC_ARROW); wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1); wc.lpszMenuName = NULL; wc.lpszClassName = g_szClassName; wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION); if(!RegisterClassEx(&wc)) { ErrorBox("Window Class Registration Failed!"); return 0; } /* Create the Window */ hwnd = CreateWindowEx(WS_EX_CLIENTEDGE, g_szClassName, "The title of my window", WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, 240, 120, NULL, NULL, hInstance, NULL); if(hwnd == NULL) { ErrorBox("Window Creation Failed"); return 0; } ShowWindow(hwnd, nCmdShow); UpdateWindow(hwnd); /* Run Message Loop */ while(GetMessage(&Msg, NULL, 0, 0) > 0) { TranslateMessage(&Msg); DispatchMessage(&Msg); } return Msg.wParam; } What is a little bit unusual is the ErrorBox function : often, a message box simply reports the error and aborts the program. ErrorBox uses GetLastError() and FormatMessage() to provide somewhat more information. By accident, let's make an error, commenting out the RegisterClassEx() call : #if 0 if(!RegisterClassEx(&wc)) { ErrorBox("Window Class Registration Failed!"); return 0; } #endif Under Windows (tested with NT4 and XP), the displayed message (by ErrorBox) is: == Window Creation Failed: 1407: Can't find window class == But, under wine (20021219), the displayed message is, unfortunately : == Window Creation Failed: 0: No error == While looking inside the wine sources, it appears that no error code is set in the functions 'CreateWindowExA' in windows/win.c file when the window's class is not found : an error message is printed and 0 is returned. The following adds the appropriate error code in function CreateWindowExA : around line 1291 and 1301: SetLastError(ERROR_CANNOT_FIND_WND_CLASS); before the return 0; Questions : does it have any interest for wine to add these error codes ? If yes, according to DLL separation, is it allowed to call SetLastError() in any context ? Should I submit a patch ? Any other feedback ?

problem building tests with msvc6

Jan. 14, 2003

Trying to build conformance tests on Windows Me with msdev6, but got the following link errors: safearray.obj : error LNK2001: unresolved external symbol _IID_IStorage safearray.obj : error LNK2001: unresolved external symbol _IID_IDispatch safearray.obj : error LNK2001: unresolved external symbol _IID_IUnknown Output\Win32_Wine_Headers/oleaut32_test.exe : fatal error LNK1120: 3 unresolved externals Any suggestions? (Sorry to act so helpless...) FWIW, here's the full recipe I followed: On linux: cd ~/wine msvcmaker --no-wine find *.dsp *.dsw include */*/tests -name CVS -prune -o -type f -not -name '*.o' -not -name '*.so' -not -name '*.ok' -not -name '*.spec.c' -print | cpio -oH tar | gzip > wtest.tgz sudo cp wtest.tgz /dos/c reboot On Windows Me: (install msvc6) (install cygwin) cd c:/ mkdir wtest cd wtest tar -xzvf ../wtest.tgz start c:/wtest/wineruntests.dsw rebuild all -- Dan Kegel Linux User #78045 http://www.kegel.com

Problem with interrupt vector
by Gustavo Junior Alves Jan. 14, 2003

Jan. 14, 2003

Hi, Since 20021107, some programs is not functional anymore. The problem begins with change of INT_GetPMHandler to DOSVM_GetPMHandler16. When the function try to read the interrupt vector, the app crashs, with following error message: Unhandled exception: page fault on read access to 0x00000090 in 32-bit code (0x41cc7cb3). In 32-bit mode. 0x41cc7cb3 (WINEDOS.DLL.EmulateInterruptPM+0x30b in winedos.dll.so): movl 0x0(,%eax,4),%eax Any ideas about this problem?? How I can fix this? Thanks, Gustavo Junior Alves alves(a)coslinux.com.br

Re: Add filesytem type NTFS to config

Just curious tony, but if that's the case why doesn't Wine return NTFS all the time? Are there some apps that actually won't run if it returns NTFS at all?

If no one complained, it's probably OK until Alexandre gets around to it. He can't reply in real time, wait for a few days. If you see commits going in (subscribe to, or check the mail archives for wine-cvs(a)winehq.org to monitor the checkins) and yours is not applied, email and ask him what's up. -- Dimi.
