/* * Microsoft Confidential * Copyright (C) Microsoft Corporation 1991 * All Rights Reserved. * * * PIFMGR.C * Main module for PIFMGR.DLL * * History: * Created 31-Jul-1992 3:30pm by Jeff Parsons * * Exported Program Information File (PIF) Manager services: * * PifMgr_OpenProperties() * Give it the name of an DOS application (com, exe, or bat), * and it will open the PIF associated with that application * and return a "handle" to the app's "properties". Use this * handle when calling any of the other "properties" services (ie, * Get, Set, and Close). * * If no PIF exists, it will still allocate a PIF data block * in memory and initialize it, either with data from _DEFAULT.PIF * or its internal defaults. It will also construct the PIF name * it was looking for but couldn')t find and save that in its internal * PIF data structure, so that if PifMgr_SetProperties is ever called, the * data can be saved to disk. * * PifMgr_GetProperties() * Returns the specified block of data from the associated PIF. * If it is a "named" block, it must be the name of a linked * extension inside the PIF, which can be any predefined name * (eg, "WINDOWS 386 3.0") or the name of your own block. You can * create your own named data blocks using the PifMgr_SetProperties() * service. "Named" data can also be thought of as "raw" data, * because it is returned to the caller as-is -- without translation. * * The size of a named block can be determined by calling * PifMgr_GetProperties with a size of zero; no data is copied, but the size * of the requested block is returned (0 if not found). * * All named blocks can be enumerated by passing NULL for the name, * a pointer to a 16-byte buffer for the requested block name, and a * 0-based block index in the size parameter. The size returned * is the size of the block (0 if none). * * If an unnamed property block is requested (ie, the selector of * the name parameter is NULL, and the offset is a property group * ordinal), then the associated structure is returned. For example, * PifMgr_GetProperties(GROUP_TSK) returns a predefined structure (see * PROPTSK in PIF.H) containing all the tasking-related information, * in a format that is PIF-independent. This is a valuable service, * because it relieves callers from having to cope with PIFs * containing a wide variety of sections (known as PIF extensions), * only one of which is required. Think of this as "cooked" data. * * A third variation is raw read/write of the entire PIF data block, * if lpszGroup is NULL. This must be used with extreme caution, and * will only be allowed if the properties were opened with the * OPENPROPS_RAWIO flag specified. * * PifMgr_SetProperties() * This is pretty much the opposite of PifMgr_GetProperties, except that it * also takes a flags parameter that can specify that the changes * be made immediately, or deferred to PifMgr_CloseProperties. * * PifMgr_CloseProperties() * Flushes any dirty PIF data in memory, and frees the local heap * storage. * */ #include "shellprv.h" #pragma hdrstop #ifdef _X86_ /* Global R/W DLL data */ PPROPLINK g_pplHead; // pointer to first prop entry HANDLE g_offHighestPropLink; // highest offset of a prop thus far recorded TCHAR g_szNone[16]; // initialized by LibMainP, TCHAR g_szAuto[16]; // and 16 chars to allow for localization char g_szMSDOSSTSFile[] = "C:\\MSDOSSYS.STS"; TCHAR g_szConfigFile[] = TEXT("C:") CONFIGFILE; TCHAR g_szAutoexecFile[] = TEXT("C:") AUTOEXECFILE; TCHAR g_szMConfigFile[] = TEXT("C:") MCONFIGFILE; TCHAR g_szMAutoexecFile[] = TEXT("C:") MAUTOEXECFILE; TCHAR g_szWConfigFile[] = TEXT("C:") WCONFIGFILE; TCHAR g_szWAutoexecFile[] = TEXT("C:") WAUTOEXECFILE; #ifdef DBCS char ImeBatchFile[] = "DOSIME\0"; #endif #define NT_CONFIG_FILE "%SystemRoot%\\SYSTEM32\\CONFIG.NT" #define NT_AUTOEXEC_FILE "%SystemRoot%\\SYSTEM32\\AUTOEXEC.NT" #define LPPH_OFF(off) ((LPBYTE)lpph + off) #define LPPIF_FIELDOFF(off) ((LPBYTE)ppl->lpPIFData + FIELD_OFFSET(PIFDATA,off)) #define LPPIF_OFF(off) ((LPBYTE)ppl->lpPIFData + off) // // g_szDefaultPIF can be in one of three states: // // 1.

When TRUE, the position, fonts, and * toolbar state of a non-Windows application whose settings * have not been previously saved in the DOSAPP.INI file will * not be saved. * * If enabled, the setting can be overridden for each * non-Windows application by selecting the Save Settings On * Exit check box in the Font dialog box. * * To change: * * Use Notepad to edit the SYSTEM.INI file. * * Compatibility notes: * * In Windows 3.x, the "position save" (and font) information was * saved in DOSAPP.INI, and although we will still read DOSAPP.INI * in the absence of any information in the PIF file, we only *write* * settings back to the PIF file. DOSAPP.INI should be considered * obsolete. * * * TTFont= * * Status: ? * Default: Courier New // FEATURE -- this should be a TT OEM font * Purpose: * * This setting allows the user to specify which TrueType font * will be used in a DOS box. It must be an OEM font. * * To change: * * Use Notepad to edit the SYSTEM.INI file. * * * TTInitialSizes= * * Status: ? * Default: 4 5 6 7 8 9 10 11 12 14 16 18 20 22 36 72 * Purpose: * * This setting allows the user to specify which font sizes * WinOldAp initially builds for the TrueType fonts in a DOS * application window. * * At most 16 font sizes can be requested. * * Note that this INI entry is consulted only the first time * Windows is restarted after changing video drivers or fonts. * * To change: * * Use Notepad to edit the SYSTEM.INI file. * * * TTHeuristics= * * Status: Public * Default: 5000 1000 0 1000 5000 1000 0 1000 1 * Purpose: * * These integers control the way Windows chooses the font to * display for DOS applications running inside a window if you * have chosen "Auto" as the font size. * * The parameters are named as follows: * * i1=XOvershootInitial * i2=XOvershootScale * i3=XShortfallInitial * i4=XShortfallScale * i5=YOvershootInitial * i6=YOvershootScale * i7=YShortfallInitial * i8=YShortfallScale * i9=TrueTypePenalty * * Each penalty value may not exceed 5000. * * When Windows needs to select a font for use in a DOS * application's window, it goes through the list of font * sizes available and computes the "penalty" associated * with using that font. Windows then selects the font with * the smallest penalty. * * The horizontal penalty is computed as follows: * * Let dxActual = * Let dxDesired = * * * If dxActual = dxDesired: * xPenalty = 0 * If dxActual < dxDesired: * Let Ratio = 1 - dxDesired / dxActual * xPenalty = XOvershootInitial + Ratio * XOvershootScale * If dxActual > dxDesired: * Let Ratio = 1 - dxActual / dxDesired * xPenalty = XShortfallInitial + Ratio * XShortfallScale * * The vertical penalty is computed similarly. * * Note that the Ratio is always a fraction between 0 and 1. * * The penalty associated with a font is the sum of the vertical * and horizontal penalties, plus the TrueTypePenalty if the font * is a TrueType font. * * The default value of 1 for the TrueTypePenalty means that, * all other things being equal, Windows will select a raster * font in preference to a TrueType font. You can set this * value to -1 if you wish the opposite preference. * * To change: * * Use Notepad to edit the SYSTEM.INI file. * * Internals: * * Even though floating point appears in the computations, * everything is really done in integer arithmetic. * * Pixels are NEVER MENTIONED anywhere in the penalty computations. * (All pixel values are divided by other pixel values, so that * we get a dimensionless number as a result.) * This keeps us independent of the display resolution as well * as the display aspect ratio. * * Since the stretch and shrink are taken as fractions of the * larger dimension, this keeps us from penalizing large * differences by too much. This is important because there * isn't much visible difference between being ten times too * big and being eleven times too big, but there is a big * difference between being just right and being twice as big. * * We must be careful not to let the maximum possible penalty * exceed 32767. This is done by making sure that each * dimension cannot produce a penalty of greater than 10000 * (5000+5000), and that the TrueTypePenalty is at most 5000. * This makes the maximum possible penalty 25000. * This range checking is done by FontSelInit. * * * TTNonAspectMin= * * Status: Public * Default: 3 3 * Purpose: * * These integers control the minimum width and height font that * Windows will attempt to create automatically in response to a * resize operation when TrueType fonts in DOS boxes are enabled * and the "Auto" font size is selected. * * These values prevent Windows from creating visually useless * fonts like 10 x 1 or 1 x 10. The default values prevent Windows * from trying to create X x Y fonts if X < 3 or Y < 3. * * TTNonAspectMin is not consulted if the font is being created at * its default aspect ratio. In other words, Windows will create, * for example, a 1 x 3 font, if 1 x 3 is the standard aspect ratio * for a 3-pixel-high font. * * To permit all aspect ratios, set the values to "0 0". * * To forbid all aspect ratios except for the standard aspect ratio, * set the values to "-1 -1". * * [TTFontDimenCache] * * dxWidthRequested dyHeightRequested=dxWidthActual dyWidthActual * * Status: Private * Default: Null * Purpose: * * The [FontDimenCache] section contains information about * TrueType font sizes that have been created. Each entry * has as the keyname the width and height that were passed * to CreateFont and has as the value the width and height of * the font that was actually created. * * Internals: * * Inspected by AddTrueTypeFontsToFontList. * Set by AddOneNewTrueTypeFontToFontList. * * ************************************************************************** * * DOSAPP.INI (obsolete, supported on a read-only basis) * * [Dos Applications] * * C:\FULL\PATH\TO\EXE\COM\BAT\OR.PIF= * * Status: Private * Purpose: * * These values are used to restore a DOS application's window * to the state it was in when the DOS app last exited normally. * * The values are taken directly from the INIINFO structure, qv. * * The values of ptMinPositionX and ptMinPositionY are always -1, * since we do not try to preserve the icon position. * * If wFontHeight has the high bit set, then the font that * should be used is a TrueType font. * * If wFontWidth = 1 and wFontHeight = -1, then * Auto-font-selection is active. * * Compatibility notes: * * In Windows 3.x, the "position save" (and font) information was * saved in DOSAPP.INI, and although we will still read DOSAPP.INI * in the absence of any information in the PIF file, we only *write* * settings back to the PIF file.
