Programs

  Projects, individual procedures and useful lines of code in PowerBASIC version 10. And some ancillary notes. If you don't have PowerBASIC it should not be too hard to translate the functionality (command-by-command is often non‑optimal). In some cases I have included a compiled DLL, making it out-of-box usable in older PowerBASICs and other lanuages. Items below are considered complete if preceded by a date (ISO basic format) in brown.

• Completed Projects (till updated ☺)
  • SI/ISO Tools International System of Units/International Organization for Standards
  • 20221209 SI Prefix Format function.
  • 20221206 SI Quantity and Unit Names, and Symbols data.
  • Unicode Tools
    • 20210826 Grabber Select, copy then paste to "grab" a character and get its decimal or hexadecimal for CHR$$() in PB HTML composing.
    • 20250622 Alphabets of many languages, and special characters. Get characters, symbols and other glyths not on your keyboard. Or, copy the decimal, or hexadecimal, value for web page composing or progamming source code.
  • Network Tools
    • a tool
• Works In Progress Some works in progress, not completed code. An incomplete project may contain useful completed procedures. They will be here in sub-lists. This is also a form of off-site backup for both complete and uncompleted code. A seggestion may help me "loosen up" a stalled project.
  • (stalled) DY HTML Edit Create and edit web page files, CSS (Cascading Style Sheet) files or embedded in HTML CSS, and Javascript files or embedded in HTML files. The editor I have been using does not handle non-ANSI characters. Characters with code points 128 to 255 are correctly saved as two byte UTF-8, but those above are changed to a similar ASCII character or a question mark (?). This editor work internally in 2 byte UTF-16, then saves as a true UTF-8 file.
  • (just extremely slow) VLU Arithmetic. "VLU" ia an acronym for "Very Large Unsigned" number. The numbers are arrays of 16 bit base 65536 digits. Larger base reduces the number of operations to do a calculation. The limit is accessable memory.
    • Addition.
    • (Subtraction, code but no page)
    • (Multiplication, code but no page)
    • (Division, "filler page" no code in page)(( A "bear" to figure out. HELP!!))
    • Square Root , page with notes and a bit pseudo code( A double "bear" to figure out.))
    • 20211224 Compare. Is the second VLU greater than, less than or equal to the first VLU.
    • 20211221 Trim. Remove any leading zero VLU digits from array.
  • (stalled) bBaseW My update of xBase database. "b" for binary numbers, numbers as character numeric field types kept. The "W" is UTF-16 text field type added.
• Miscellaneous Complete procedures (SUBs or FUNCTIONs), code lines or fragments to use in a project.
  • 20240907 Faster leap year algorithm, and discussion about why others are slower.
  • 20240609 W3 Foreground/background contrast ratio calculation.
  • 20230908 Listbox with "sunken" appearance.
  • 20230313 High resolution interval counter. Use like PB TIX with one programmer provided Quad, with better stability.
  • 20230314 High resolution timestamp. Maintains sequence of close spaced time stamps.
  • 20230612 Fixed (mono-spaced) Font Messagebox Intended for compiling and use with PowerBASIC Console compiler. Will work with PowerBASIC For Windows. A compiled DLL is available for users of older PB versions and other languages.
  • 20250412 Endian Swap Convert numeric types to/from most significant byte left (big endian) and most significant byte right (little endian).
  • 20250512 App shows HTML in default browser.
  • 20250518 Error Codes include of error code constants based on PowerBASIC 8 bit and/or Windows' 32 bit codes (Windows' "user assigned code" bit as needed).
    Never really finished. If I need to trap an error that I didn't before, a code will be added (existing codes not changed). Additional error code suggestions/requests will be considered.
• Ancillary Info
  • 20231017 Text in ASMDATA Reduces time and memory useby not copying to variable, and has advantages over equates. Demonstration of technique, no "ready-to-use" function.
  • 20231019 Font List Just a list of UTF-16 proportional and mono-spaced fonts in MS Windows having characters used in many lanuages, symbols and box drawing glyphs. The proportional ones may, or may not, have box drawing; inly mono-spaced fonts recommended when using box drawing (presence of right-to-left and asian characters was not considered).
  • 20230319 Notes About Time In Windows And comments on PowerBASIC time procedures.
  • 20211101 How To Install A Program
  • 20240505 BBROYGBVGW Color code equates.
  • 20240517 TextColorByBackgound auto calculate.
  • 20241020 About Filetime.
  • 20241223 OR versus + Declaring Window Styles.
  • 20240215 IN_Addr_IN6_Addr_ChangeSuggest
