i am a n00b with no programming knowledge but i managed to make a couple of working scripts with autoit ... but now i am stuck...

i am trying to get a script that would write all the possible number combinations consisting of X digits to a file...

for example all possible 4-digit combinations and write them to a file like this...

```0000
0001
...etc
9998
9999```

i think it like permutations ... but i dont know how to do it ...

so, i though that the closest method (that i can do) is to write a script in which i choose a number to start with and get the script to add 1 until reaching a number that i chose to finish with ...

so in the mentioned example i would set 1000 as the start and 9999

here is what i came up with....

```#include <File.au3>

\$End= InputBox("Enter Number to End With", "End With:")
\$File = @ScriptDir & "\file.txt"
_FileCreate(\$File)
FileOpen (\$File, 1)
FileWriteLine (\$File, \$Start)
FileClose (\$File)
Do
FileOpen (\$File, 0)
FileClose (\$File)
FileOpen (\$File, 1)
FileWriteLine (\$File, \$Finish + 1)
FileClose (\$File)
Until \$Finish= \$End
MsgBox(1,"Finished", "DONE!")
Exit```

but it's not working and it stays in a loop writing 1 in every line of the file

```1
1
1
1
1
1
1
1
1
...etc```

also, that way i would be missing 0001 to 0999 but i thought if i can get the script to work i will do from 0-9 ,10-99 and 100-999 and write another script to add the missing zeros to the start...

can someone help me make the file it with a better method or at least get this one to work....

Try this method instead:

```\$Start = InputBox("Enter Number to Start With", "Start With:")
\$End = InputBox("Enter Number to End With", "End With:")
\$File = @ScriptDir & "\file.txt"
\$WriteFile = FileOpen(\$File, 2)
FileWriteLine(\$WriteFile, "Starting Number = " & \$Start)
For \$I = \$Start To \$End
FileWriteLine(\$WriteFile, \$I)
Next
FileClose(\$WriteFile)
MsgBox(1, "Finished", "DONE!")```

If you want to have the 0s in front of the number for those lower than 1000, try this:

```\$Start = InputBox("Enter Number to Start With", "Start With:")
\$End = InputBox("Enter Number to End With", "End With:")
\$File = @ScriptDir & "\file.txt"
\$WriteFile = FileOpen(\$File, 2)
FileWriteLine(\$WriteFile, "Starting Number = " & \$Start)
For \$I = \$Start To \$End
Switch \$I
Case 1 to 9
\$I = "000" & \$I
Case 10 to 99
\$I = "00" & \$I
Case 100 to 999
\$I = "0" & \$I
EndSwitch
FileWriteLine(\$WriteFile, \$I)
Next
FileClose(\$WriteFile)
MsgBox(1, "Finished", "DONE!")```

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

This script answers your original intention. Someone please check my logic/math to make sure I am thinking correctly.

```#include <File.au3>

Local \$String
\$Digits = InputBox("Enter Number digits to permutate", "Number of Digits:")
If @error Then Exit
\$File = @ScriptDir & "\file.txt"
\$End = 10 ^ \$Digits - 1
For \$i = 0 To \$End
\$String &= StringFormat("%0" & \$Digits & "i", \$i)
If \$i <> \$End Then \$String &= @CRLF
Next

_FileCreate(\$File)
FileOpen(\$File, 1)
FileWrite(\$File, \$String)
FileClose(\$File)
MsgBox(1, "Finished", "DONE!")```

Of course you could have eliminated your Switch with

```For \$i = \$Start To \$End
FileWriteLine(\$writefile, StringFormat("%03u", \$i))
Next```

Edit: you can substitute "d" for the "u" in the StringFormat call

I always forget about StringFormat. I probably could have used it in a few places in my media player...hmmm maybe I will do that after all.
