/* OLE SERVER DEMO SrvrDemo.h This file contains typedefs, defines, global variable declarations, and function prototypes. (c) Copyright Microsoft Corp. 1990 - 1992 All Rights Reserved */ /* Explanation of Function Comments. Every function has a comment preceding it which gives the following information: 1) Function name. 2) A description of what the function does. 3) A list of parameters, each with its type and a short description. 4) A list of return values, each with an explanation of the condition that will cause the function to return that value. 5) A customization section giving tips on how to customize this function for your OLE application. If the customization section says "None" then you may find the function usable as is. If the customization section says "Re-implement" then the function should still serve the same purpose and do what is indicated in the function comment, but will probably need to be re-implemented for your particular application. Any Server Demo code relating to OLE will be useful as a guide in your re-implementation. If the customization section says "Server Demo specific" then the function will probably have no counterpart in your application. */ /* Menu Identifiers */ // File menu #define IDM_NEW 100 #define IDM_OPEN 101 #define IDM_SAVE 102 #define IDM_SAVEAS 103 #define IDM_EXIT 104 #define IDM_ABOUT 105 #define IDM_UPDATE 106 // Edit menu #define IDM_CUT 107 #define IDM_COPY 108 #define IDM_DELETE 109 // Color menu #define IDM_RED 110 #define IDM_GREEN 111 #define IDM_BLUE 112 #define IDM_WHITE 113 #define IDM_GRAY 114 #define IDM_CYAN 115 #define IDM_MAGENTA 116 #define IDM_YELLOW 117 // New object menu #define IDM_NEWOBJ 118 #define IDM_NEXTOBJ 119 #define IDD_CONTINUEEDIT 120 #define IDD_UPDATEEXIT 121 #define IDD_TEXT 122 #define OBJECT_WIDTH 120 #define OBJECT_HEIGHT 60 // number HIMETRIC units per inch #define HIMETRIC_PER_INCH 2540 /* Types */ // Document type typedef enum { doctypeNew, // The document is untitled. doctypeFromFile, // The document exists in a file and may be linked. doctypeEmbedded // The document is an embedded document. } DOCTYPE; // Device context type, passed to DrawObj. typedef enum { dctypeScreen, dctypeBitmap, dctypeMetafile, dctypeEnhMetafile } DCTYPE ; // Version typedef WORD VERSION; // Verb typedef enum { verbPlay = OLEVERB_PRIMARY, verbEdit } VERB; // Server structure typedef struct { OLESERVER olesrvr; // This must be the first field so that // an LPOLESERVER can be cast to a SRVR*.
