Upon normal execution of the main application, Facade releases itself from memory, thus adding no overhead to the executable sequence. The splashscreen displays for four (4) seconds, then calls the main executable just as it would have been executed from the system prompt. Facade may be used with most traditional MS-DOS language executables, including those created with CA-Clipper, Borland Turbo Pascal, QuickBASIC, PowerBasic, Visual Basic(tm) for DOS, FoxPro, dBase, Clarion, C, etc. Facade image displays will run under both DOS and Windows (full DOS screen). The utility is particularly effective for software developers preparing copyright or other splashscreens of their products. The chief advantages, aside from the presentations themselves, are both low cost and method of acquiring. The copy included herewith is a fully-functional evaluation copy available easily and universally through the user-supported software marketplace. Please note there is a similarly-named version of Facade called Facade-C (Facade for Clipper), also from RCCO Research, which is specifically designed for developers using CA-Clipper(R). The present version of Facade will also work well with Clipper, but we must point out the similar names to help avoid confusion about the two products. Facade.exe and the sample files -------------------------------- To run the files included in this package (FACADE.EXE and 2 sample files: _ADMIN.PCX, _OVERL.EXE) simply execute FACADE from the DOS prompt. Preparation of images ---------------------- Facade is particularly effective for software developers preparing copyright or other splashscreens of their products, in that they can easily capture usable materials with programs like Hijaak(tm) for Windows and modify or create them in editing programs such as Windows(tm) Paintbrush. The only requirement is that images must be finally saved in 640x480 16- color VGA .pcx file format. If you are doing image preparation in Windows, you will have to load a 16-color video driver for 640x480 VGA in order to prepare proper images. This format is used since it is the most universal that will allow presentations to be viewed on as many DOS and/or Windows VGA systems as possible. Do not build your images with 256 or more colors as they will not display with Facade. The end-user should then be able to properly display using any VGA card and driver with 16 or more colors; it is only during the preparation and saving of .pcx images that you must use a 640x480x16 driver. We have observed excellent, consistent results with using a program such as Hijaak(tm) for Windows to capture entire DOS or Windows screens, or selected areas of screens, or a particular window on a full Windows screen. The preparer then does final editing, adding text, drawing lines or other objects, in a drawing program. For example, the sample sign-on screen provided with this package was done entirely in the program that comes free with Windows: Paintbrush. The inset picture was captured from a black and white line drawing with a hand scanner and edited in Paintbrush. Other graphics programs are likely to provide compatible material, but they must be tried on a test basis with Facade. The two programs mentioned above work well for most users, are widely available, and do not require great technical or professional ability. Scanned images will be effective in Facade if they are saved in the proper format. If one format you are using seems not workable, try saving that image in another program, such as Windows Paintbrush; we have often found that certain images work better when converted or simply saved in another program's format even though they may use the same .pcx extension. When attempting to use monochrome pcx files, resave them as 16-color 640x480 VGA pcx files. Even though the appearance may remain the same, they will be saved in a format usable by Facade. Once you find the right combination of steps to produce pcx file formats consistently usable by Facade, you will save a great deal of time and effort by always using that combination in future applications. Required naming convention for the .pcx file --------------------------------------------- After you have prepared the desired .pcx file, simply rename it _ADMIN.PCX The basic requirement is that the image file and the related executables be placed in the same directory on a hard drive. You should advise end-users against running your application from a floppy diskette, due to the slowness of building the on-screen image when reading from a diskette. Your end-users will certainly need VGA graphics capabilities to view your splashscreen. If a user attempts execution on a non-VGA-capable system, a simple screen will very briefly display the message ÉÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍ» º º º Loading application... º º º ÈÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍÍͼ This software program contains copyrighted material. All Rights Reserved under International Conventions. and continue without much delay. (The wording on this screen may be changed by the developer with a hex editor, if desired.) Renaming the related executables --------------------------------- The developer's executable application to be launched should be renamed _OVERL.EXE (or _OVERL.COM, if a .com file) The file FACADE.EXE would be then renamed to 'MYAPP.EXE' or whatever the developer's application was originally called, so that the end-user executes the original program name. The calling sequence then becomes: MYAPP.EXE displays _ADMIN.PCX (if VGA system is found) then executes _OVERL (.exe or .com) at which point the developer's original application (now called _OVERL.EXE or _OVERL.COM) will take over and execute normally. Please recall that very early versions of DOS will not support renaming of executable files; in 1994 and beyond, we trust this will no longer present a problem. Clipper developers please take note of the Clipper-specific comments about renaming the main application, under the section Troubleshooting, below. You need not issue a clearscreen command at the beginning of your applica- tion. Facade clears the screen automatically upon exiting. Troubleshooting ---------------- One caveat we might offer with this program is that if you find that your images do not display, or do not display properly, it is probably because they have been created or saved in a format that may only be slightly incompatible with that which Facade requires. Before you decide that the Facade program is not usable in such instances, try the suggestion given before for re-saving your .pcx files in another graphics program. Most image-editing programs will read files in several formats, and often allow conversions, or perhaps will save them in a later .pcx format that will work with applications such as Facade. Also, make certain that images are saved in 640x480 by 16-color format by using the proper software and/or video drivers to handle the format. Any developer who uses the .RTLink linker and experiences loading errors with their applications and Facade should be cognizant of the information provided below for Clipper users and be prepared to make similar adjustments, if needed. Please let us know if you have continued or other difficulties in making Facade work as described, as well as any solutions or workarounds you may have found. Clipper-only: -------------- CA-Clipper(R) 5.x developers using .RTLink or BLINKER who experience runtime unrecoverable error messages 415 (cannot open overlay file) or 416 (read error on overlay file) when renaming their executable files to _OVERL.EXE with the DOS REN command should simply relink the executable as follows: specify in the .lnk file that the output name is to be _OVERL.EXE (i.e., OUTPUT _OVERL). Developers using BLINKER's SwpRunCmd() function should well-test any application that is loaded with Facade. If you experience a swap error when attempting to return from a SwpRunCmd() call, you should consider whether or not that Blinker function is absolutely essential to the application. We know of no workaround at this time other than using the Clipper RUN command. Clipper 5.x developers may also wish to evaluate the companion program, FACADE-C (Facade for Clipper), a special version of Facade that addresses Clipper-only issues, including elimination of any momentary screen delay from the time that Facade calls _OVERL.EXE to the time that it takes for a large Clipper application to load (Facade-C, with provided Clipper coding, will allow the Clipper application to load during the time the pcx image is displayed on the screen). Facade-C also provides for a default command-line setting of //E:0 //F:31. The length of time the image is displayed to the end-user may be specified by the developer (standard Facade is set at an invariable 4 seconds). While adding some coding (usually about six lines) on the part of the Clipper developer, Facade-C differs from the standard version of Facade in that it is slightly less convenient to set up and use. Facade-C is significantly different in internal operation from standard Facade and may offer an advantage for the serious Clipper developer. The executable file sizes for Facade and Facade-C are very similar, however -- a factor that should appeal in particular to the Clipper developer. A fully-functional evaluation copy of Facade-C may be obtained from traditional user-supported software sources, including the Clipper forum library on CIS and from PsL, Public (software) Library (800-242-4775 or 713-524-6394). Program Requirements --------------------- The requirements for running Facade include a DOS-compatible PC with 512k memory, VGA graphics capability, and a hard drive. DOS 3.1 (or later) or Windows 3.x (or later) should be utilized.
