Welcome to my domain. This is an open space where I, Jeffrey Riaboy, am keeping a compendium of my projects, thoughts, news, and miscellaneous ideas. I am a self taught programmer/computer nerd that works in C++ by choice, and too many other languages due to the facts of life. I have been programming virtually my whole life and working with computers since before I can remember. They are my passion, hobby, job, first love, and have served me well, though, been a constant pain in the anatomy. I hope you can find something of interest or use here, as that is the reason I spend my time creating and organizing this content. Enjoy. ^_^
The original (well... last) intro page to my website before this became the home. It is a flash portal to my personal sites of the past.

Updates Archive
Section: Projects > DWCF
  • DSQL v2.0.2.2
    • Added ability via DSQL->$StrictMode variable to update MySQL strict mode
    • Added DSQL->RawQuery() function which takes just a query, and does no modification on it. I found this required due to extremely slow times on building very large queries.
    • Added DSQL->EscapeString() function which escapes a string for use in a mysql query. It has an optional parameter that adds single quotes around the result.
    • Added DSQL::PrepareInsertList() function which takes an array of names, and turns it into the following string: ['a', 'b', 'c'] => “(`a`, `b`, `c`) VALUES (?, ?, ?)”
  • DWCF v1.1.1
    • Added previous variable lookup to GetVars.VarArray.SQLLookup via %THEVAR-$VARNAME%
Section: Projects > DWCF
DWCF v1.1 updates
  • Added functionality:
    • GetVars.VarArray.SQLLookup:
      • Additional string parameters that have %THEVAR% are replaced with the value being checked
      • If the first item is NULL, it will be removed, and the return will include full rows ("*") of the query result set
  • Updated functionality:
    • json_encode() In RetMsg() and CallByAction() now use JSON_UNESCAPED_UNICODE
    • GetVars.VarArray.IsOptional now only triggers if it is (boolean)true
    • Added additional description specification to GetVars.VarArray.SQLLookup which says it uses the additional parameters as values to fill in the SQL Query
  • LICENSE: Now applies to 1.x instead of 1.0.x

Section: Projects > DSQL
DSQL v2.0.2
  • Added static member $InitialPrintAndDieOnError which DSQL.PrintAndDieOnError inherits on creation
  • Bug Fixes:
    • mysqli_set_charset is set to utf-8
    • In FormatSQLError() the date() function used for “Start Time” now uses “24-hour format of an hour with leading zeros” [date(“H”)] instead of “12-hour format of an hour without leading zeros” [date(“g”)]

Babyface Pro Volume Modification via Mousewheel

Part of my workstation’s audio setup uses the RME Babyface Pro. Until the most recent update of their software, the built-in Window’s sound’s master volume for the device was ignored. So while this script isn’t as important as before, I still find it very useful. So the following is an AutoHotkey script which modifies the master volume in the TotalMix FX window via the mousewheel (when alt+ctrl is held down). This expects the TotalMix FX window to be sized as small as it can, and to have a channel selected for the control room’s Main Out. It should look like this:

TotalMix FX Sized For Volume Modification

The script is as follows:
;Function to create lparam/wparam for SendMessage
CalculatePARAM(w1, w2)
	IfLess, w1, 0
		w1 := 65535 + w1 + 1
	IfLess, w2, 0
		w2 := 65535 + w2 + 1

	return (w2<<16 | w1)

;Send a mouse wheel action to a window
SendMouseWheel(WindowHWND, Steps, XPos, YPos)
	WheelStepAmount := 120

	;Calculate and execute the message
	WinGetPos, ScreenX, ScreenY,,, ahk_id %WindowHWND%
	wparam := CalculatePARAM(0, Steps*WheelStepAmount)
	lparam := CalculatePARAM(XPos+ScreenX, YPos+ScreenY)
	SendMessage, %WM_MOUSEWHEEL%, %wparam%, %lparam%,, ahk_id %WindowHWND%

ControlGet, ControlHWND, Hwnd,,AfxFrameOrView100s1,RME TotalMix
if ControlHWND
	SendMouseWheel(ControlHWND, 1, 36, 428)

ControlGet, ControlHWND, Hwnd,,AfxFrameOrView100s1,RME TotalMix
if ControlHWND
	SendMouseWheel(ControlHWND, -1, 36, 428)
MD5Sum List Script
#This script takes a newline delimited file list from STDIN for md5 hashing
#This script requires the `md5sum`, `pv`, `paste`, `bc`, and 'numfmt' commands

#The output of the md5s are stored in the file specified by the first parameter
#The format for each md5 hash to the output file is "$FileName\t$Hash\n"

#File sizes are always output in megabytes with 3 decimal places
#While calculating the hashes the script keeps the user informed of the progress of both the current file and all the files as follows:
#1) "Hashing: $FileName ($FileSize MiB)\n"
#2) The progress of the hash of the file ran through `pv`, with the size precalculated for file progress percents
#3) "Finished $TotalProgressPercent% ($ProcessedBytes/$TotalBytes MiB)\n\n"

#Get $Outfile from the first argument and the $FileList from STDIN (newline delimited)
FileList=`cat /dev/stdin`

#Format a byte count in MegaBytes with comma grouping and 3 decimal places
MbFmtNoExt ()
	echo "scale=3; $1/1024/1024" | bc | echo -n `xargs numfmt --grouping`

#Add " MiB" to the end of MbFmtNoExt
MbFmt ()
	echo `MbFmtNoExt $1`" MiB"

#Calculate and output the total size of the file list
echo -n "Calculating total size: "
TotalSize=`echo "$FileList" | xargs -d"\n" stat --printf="%s\n" | paste -s -d+ | bc`
MbFmt $TotalSize
echo #Add an extra newline

#Run over the list (newline delimited)
for FileName in `echo "$FileList"`
	#Output the file size and name to STDOUT
	FileSize=`stat --printf="%s" "$FileName"`
	echo "Hashing: $FileName ("`MbFmt $FileSize`")"

	#Output the filename to $OutFile
	echo -n $FileName$'\t' >> $OutFile

	#Run the md5 calculation with `pv` progress
	#Output the hash to $OutFile after the FileName and a tab
	cat "$FileName" | pv -s $FileSize | md5sum | awk '{print $1}' >> $OutFile

	#Output the current progress for the entire file list
	#Format: "Finished $TotalProgressPercent% ($ProcessedBytes/$TotalBytes MiB)\n\n"
	echo -n "Finished "
	printf "%.3f" `echo "scale=4; $CalculatedBytes*100/$TotalSize" | bc`
	echo "% ("`MbFmtNoExt $CalculatedBytes`"/"`MbFmt $TotalSize`$')\n'
Auto Locking Windows on Login

On my primary computer (whose harddrive is encrypted) I always have Windows auto logging in to help with the bootup time. However, my bootup time can be rather slow; and if I needed to have my computer booted but locked, I had to wait for the login to complete so I could lock the computer. This has been becoming a nuisance lately when I need to get out of my house quickly in the morning.

For the solution I created a windows boot entry that auto locks the computer after logging the user in. This also requires a batch file, to run for the user on startup, to detect when this boot entry was selected. Here are the steps to create this setup:

  1. Create the new boot entry: In the windows command line, run: bcdedit /copy {current} /d "Lock on Startup"
    This creates a new boot option, duplicated from your currently selected boot option, in the boot menu labeled “Lock on Startup”.
  2. (Optional) Change the bootup timeout: In the windows command line, run: bcdedit /timeout 5
    Where 5 is a 5 second timeout.
  3. Create a batch file to run on login: In your start menu’s startup folder, add a batch file. You can name it anything as long as the extension is “.bat”.
    Add the following to the file: bcdedit /enum {current} | findstr /r /c:"description *Lock on Startup" && rundll32.exe user32.dll,LockWorkStation
    Note that there are 2 spaces in the description search string to replicate the regular expression's 1 or more quantifier “+”, since findstr only supports the 0 or more quantifier “*”.
