 |
|
here's a function that'll select a random file from user defined file types... comes in handy for many tasks like wallpaper changing etc.
| Code: | total = 0
Loop, %a_scriptdir%\*.bmp
{
total += 1
}
Random, select, 1, %total%
Loop, %a_scriptdir%\*.bmp
{
IfEqual, A_Index, %select%, Setenv, file, %A_LoopFileFullPath%
}
msgbox, %file% |

Do you know of an easy way to make this file select entries from a list instead? I have a need for a script to select 5 random names daily from a set list of 493 names. Additionally, it will have to avoid repeat use of the same names.
Any ideas? |

For the names selection you could do something like this, as long as they're stored in a file with 1 name per line.
| Code: | NumberOfNames = 3 ;Number of names to choose
InputFile = Names.txt ;Name of the file where names are stored
OutputFile = Chosen.txt ;Name of the file where chosen names are stored
; This loop finds out how many names are in the file,
; if you don't need to do this, just replace this whole
; section with:
; TotalNames = # of names
Loop
{
FileReadLine, TestSize, %InputFile%, %A_Index%
If ErrorLevel
{
TotalNames := A_Index-1
break
}
}
; Chooses the names, and writes them to %OutputFile%
UsedNames =
Loop, %NumberOfNames%
{
StringSplit, UsedNames, UsedNames, |
Loop
{
LineNum =
NewName =
Random, LineNum, 1, %TotalNames%
FileReadLine, NewName, %InputFile%, %LineNum%
Loop, %UsedNames0%
{
If (UsedNames%A_Index% = NewName)
Continue
}
Break
}
UsedNames = %UsedNames%|%NewName%
FileAppend, %NewName%, %OutputFile%
}

StringSplit and multiple directory loops are very inefficient for different reasons, this should be much easier to understand:
| Code: | files = `;
Loop, *.ahk
{
files = %files%%A_LoopFileFullPath%;
total = %A_Index%
}
Random, r, 1, total
StringGetPos, p, files, `;, L%r%
StringMid, file, files, p += 2, InStr(files, ";", "", p) - p
MsgBox, %file% |
