The %MapDialogRect% function replaces the dialog-box units in with screen units (pixels), so that the rectangle can be used to create a dialog box or position a control within a box. Identifies a dialog box. Points to a %RECT% structure that contains the dialog-box coordinates to be converted. This function does not return a value. The parameter must be created by using the %CreateDialog% or %DialogBox% function. --*/ ULONG FASTCALL WU32MapDialogRect(PVDMFRAME pFrame) { RECT t2; register PMAPDIALOGRECT16 parg16; GETARGPTR(pFrame, sizeof(MAPDIALOGRECT16), parg16); WOW32VERIFY(GETRECT16(parg16->f2, &t2)); MapDialogRect( HWND32(parg16->f1), &t2 ); PUTRECT16(parg16->f2, &t2); FREEARGPTR(parg16); RETURN(0); } /*++ int MessageBox(, , , ) HWND ; LPSTR ; LPSTR ; WORD ; The %MessageBox% function creates and displays a window that contains an application-supplied message and caption, plus any combination of the predefined icons and push buttons described in the following list. Identifies the window that owns the message box. Points to a null-terminated string containing the message to be displayed. Points to a null-terminated string to be used for the dialog-box caption. If the parameter is NULL, the default caption Error is used. Specifies the contents of the dialog box. It can be any combination of the following values: MB_ABORTRETRYIGNORE Message box contains three push buttons: Abort, Retry, and Ignore. MB_APPLMODAL The user must respond to the message box before continuing work in the window identified by the parameter. However, the user can move to the windows of other applications and work in those windows. MB_APPLMODAL is the default if neither MB_SYSTEMMODAL nor MB_TASKMODAL are specified. MB_DEFBUTTON1 First button is the default. Note that the first button is always the default unless MB_DEFBUTTON2 or MB_DEFBUTTON3 is specified. MB_DEFBUTTON2 Second button is the default. MB_DEFBUTTON3 Third button is the default. MB_ICONASTERISK Same as MB_ICONINFORMATION. MB_ICONEXCLAMATION An exclamation-point icon appears in the message box. MB_ICONHAND Same as MB_ICONSTOP. MB_ICONINFORMATION An icon consisting of a lowercase i in a circle appears in the message box. MB_ICONQUESTION A question-mark icon appears in the message box. MB_ICONSTOP A stop sign icon appears in the message box. MB_OK Message box contains one push button: OK. MB_OKCANCEL Message box contains two push buttons: OK and Cancel. MB_RETRYCANCEL Message box contains two push buttons: Retry and Cancel. MB_SYSTEMMODAL All applications are suspended until the user responds to the message box. Unless the application specifies MB_ICONHAND, the message box does not become modal until after it is created; consequently, the parent window and other windows continue to receive messages resulting from its activation. System-modal message boxes are used to notify the user of serious, potentially damaging errors that require immediate attention (for example, running out of memory). MB_TASKMODAL Same as MB_APPMODAL except that all the top-level windows belonging to the current task are disabled if the parameter is NULL. This flag should be used when the calling application or library does not have a window handle available, but still needs to prevent input to other windows in the current application without suspending other applications. MB_YESNO Message box contains two push buttons: Yes and No. MB_YESNOCANCEL Message box contains three push buttons: Yes, No, and Cancel. The return value specifies the outcome of the function. It is zero if there is not enough memory to create the message box. Otherwise, it is one of the following menu-item values returned by the dialog box: IDABORT Abort button pressed. IDCANCEL Cancel button pressed. IDIGNORE Ignore button pressed. IDNO No button pressed. IDOK OK button pressed. IDRETRY Retry button pressed. IDYES Yes button pressed. If a message box has a Cancel button, the IDCANCEL value will be returned if either the ^ESCAPE^ key or Cancel button is pressed. If the message box has no Cancel button, pressing the ^ESCAPE^ key has no effect. When a system-modal message box is created to indicate that the system is low on memory, the strings passed as the and parameters should not be taken from a resource file, since an attempt to load the resource may fail. When an application calls the %MessageBox% function and specifies the MB_ICONHAND and MB_SYSTEMMODAL flags for the parameter, Windows will display the resulting message box regardless of available memory. When these flags are specified, Windows limits the length of the message-box text to one line. If a message box is created while a dialog box is present, use the handle of the dialog box as the parameter. The parameter should not identify a child window, such as a dialog-box control. --*/ ULONG FASTCALL WU32MessageBox(PVDMFRAME pFrame) { ULONG ul; UINT uType; PSZ psz2; PSZ psz3; register PMESSAGEBOX16 parg16; GETARGPTR(pFrame, sizeof(MESSAGEBOX16), parg16); GETPSZPTR(parg16->f2, psz2); GETPSZPTR(parg16->f3, psz3); // WHISTLER RAID BUG #348251 // A messagebox posted by artgalry.exe would remain behind autosketches window // after it was invoked.
