- ====== COMMON QUESTIONS BY ProWindows(tm) USERS ======
-
- ------------------------------------------------------------------
-
- QUESTION: When using the graphical mouse cursor, the mouse cursor
- in the QB or QBX editor looks funny. And when appearing
- over some characters, there is a single pixel line at
- the right of the mouse cursor. Why?
-
- ANSWER: 1. To display the graphical mouse cursor, the mouse
- driver is tricked into thinking it is in a graphics
- mode. Since the ProWindows(tm) code that keeps the
- mouse working right is not active when the program is
- not running, the mouse acts strange.
-
- For this reason, we recommend that you do not use the
- graphics mouse cursor during program development. When
- you are ready to create the EXE file, then insert the
- graphics mouse module.
-
- 2. Because of the way VGA cards operate, some
- characters are 8 pixels wide and some are 9 pixels wide.
- The mouse driver can't handle both. The only time you
- will see this line is when the cursor is over characters
- in the range of ASCII 176-178. THIS IS INHERENT TO VGA
- CARDS ONLY AND DOES NOT AFFECT EGA CARDS.
-
- When your program is finished running, you should call
- the function ResetVideo() to re-map the characters to
- thier original state.

-
- QUESTION: Why does my program quit and print a "REGISTRATION
- ENCOURAGEMENT" error message?
-
- ANSWER: Then the version you have is our ShareWare version. The
- ShareWare version works just like the registered version
- with the exception that you must call the Notice()
- routine within 60 seconds of calling the InitPro()
- routine.
-
- The Notice() routine displays a message reminding you of
- your obligation to register and pay for your copy if you
- decide to use it on a regular basis.
-
- NOTE: When you register, we will send you a disk that does not
- require the use of the Notice() routine. Because of
- this, the library is smaller and generates smaller EXE
- files.
-

-
- QUESTION: When I try to run my program in the BASIC environment, I
- get a "SUBPROGRAM NOT DEFINED" message. Why?
-
- ANSWER: In order to use an external (non BASIC) function, you
- must load them into BASIC. This is done from the
- command line by entering (for our demos) :
-
- QB /AH /L lite.qlb (for QuickBASIC)
- QBX /AH /EA /L lite.qlb (for BASIC PDS 7)
-
- To be sure that you do not pass invalid parameters to a
- function, you must include the appropriate INCLUDE (.BI)
- file(s) in your BASIC source code. To use ProWindows
- LITE functions, you would use:
-
- REM $INCLUDE : 'lite.bi'
-
- If it still does not work, go to the "Set Paths" under
- the "Options" menu in the QB.EXE (or QBX.EXE) and make
- sure that the "Include Path" points to the drive and
- directory where the ProWindows (.BI) files are.

-
- QUESTION: My programs are getting larger and i'm quickly running
- out of memory. What do I do?
-
- ANSWER: ProWindows(tm) by default uses normal DOS memory to
- allocate it's video buffer. This can easily consume up
- to 64K of memory.
-
- FEAR NOT! "WMM.EXE" may be the solution. The external
- "Window Memory Manager" attempts to convert other memory
- resources into video buffer memory. WMM.EXE can convert
- expanded (EMS) or extended (XMS). When used with
- "LOADHIGH" (DOS 5), "LOADHI" (QEMM), or similar utility,
- "upper memory" can also be converted. This utility is
- included FREE with ProWindows(tm).

-
- QUESTION: Why does the mouse cursor disappear when I print text to
- a window or the screen?
-
- ANSWER: Unlike BASIC's built-in PRINT statements (which use BIOS
- calls, ProWindows print statements (which write directly
- to video RAM) are not aware of the mouse. When printing
- text to a window, you should disable the mouse cursor,
- print the text, and then re-enable it. Try:
-
- MouseCursorOff
-
- ' text printing function
-
- MouseCursorOn

- QUESTION: Is it true that you met Elvis during the time you were
- being held captive by group of aliens from the planet
- Kaplutis?
-
- ANSWER: No, he was just an impersonator.
-

-
- QUESTION: What do I do when LINK.EXE tells me I have "TOO MANY
- SEGMENTS"?
-
- ANSWER: Cry. Just kidding! LINK defaults to 128 segments. The
- following example shows you how to increase the segments
- to 256 (but you can use higher or lower numbers):
-
- LINK /SE:256
-
- ------------------------------------------------------------------
-
- QUESTION: What can I do to make my EXE files smaller?
-
- ANSWER: The size of an EXE file is not necessarily related to
- how much memory the program will use. A good portion of
- the EXE file contains the "header" and "relocation
- table". The parts are NOT part of the program and are
- NOT loaded. They are just there to tell DOS how to load
- the program.
-
- When compiling from DOS, be sure to specify the '/EX'
- command when using LINK.EXE. This reduces the file size
- by about 30%.
-
- When you register your copy of ProWindows(tm), we will
- include a free copy of two programs that will further
- reduce the size of an EXE file by about 50% (average).
-
- We are constantly making our libraries smaller and
- smaller. As a registered user, you are entitled to FREE
- updates of the latest libraries (does not include major
- upgrades). In the last 2 months, we have made changes
- that have netted a 35% reduction in the size of
- ProWindows(tm) programs. We are not stopping there.

-
- QUESTION: What is "Video Recycling"?
-
- ANSWER: To maintain its high speed performance when manipulating
- windows, the Window Manager requires about 8K of memory
- as a "scratch pad". In standard mode, this memory is
- allocated out of the VirMem%() array and conventional
- memory.
-
- With all the memory demands placed on the system by the
- BASIC IDE and your programs, you want to limit the size
- of your arrays by as much as possible. This is the
- purpose of the VideoRecycle() routine. It forces the
- Window Manager to use the unused memory of your
- CGA/EGA/VGA cards and frees up about 24K of memory.
-
- Now you can reduce the size of the VirMem%() array and
- still maintain a large number of windows.
-
- Please note that you should only use this routine during
- program development. When creating a stand-alone EXE
- file, you should remove the command and increase the
- size of the VirMem%() array (typically to 32000).
-

-
- QUESTION: I just can't seem to get anything to work. What am I
- doing wrong?
-
- ANSWER: For every complex problem, there is probably an easy
- solution. If you get stuck, follow the next four steps:
-
- 1). Do not get mad or upset.
- 2). Take a couple of deep long breaths and relax.
- 3). Carefully read the file called "SUPPORT.DOC".
- 4). Contact DSE Technical Support in the manner
- easiest for you. Remember: There is no such
- thing as a "dumb question".

- QUESTION: Two cars are on a collision course on the Interstate.
- Cars "A" and "B" are maintaining a constant of speed of
- 65 mph and 45 mph, respectively.
-
- When the two cars are exactly 110 miles apart, a lonely
- bored fly (on a caffeine binge) starts flying from car
- "A" to car "B" at a steady speed of 92 mph. When the
- fly reaches car "B" he zips around and heads back
- towards car "A". He keeps going from car to car until
- both cars collide.
-
- How many miles did the fly travel before getting
- squashed between the two colliding cars?
