Increment downloaded image filename by one

Recommended Posts

Hi Everyone! Been away from scripting for a bit and am a bit rusty. 

I was trying to get downloaded image filenames to increment by one. I was hoping to be able to check the last filename and continue from there if the program was closed and reopened again.

#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#Region ### START Koda GUI section ### Form=
$biolister = GUICreate("Form1", 125, 97, 192, 124)
GUISetBkColor(0x99B4D1)
$start = GUICtrlCreateButton("Start", 8, 40, 41, 33)
GUICtrlSetBkColor(-1, 0x00FFFF)
$stop = GUICtrlCreateButton("Stop", 72, 40, 41, 33)
GUICtrlSetBkColor(-1, 0xFF0000)
$Bio = GUICtrlCreateLabel("Bio Lister", 24, 8, 80, 28)
GUICtrlSetFont(-1, 14, 400, 0, "MS Sans Serif")
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

While 1
    $filename = 0
    $sImgDir = "C:\filepathname\"&$filename&".jpg"
    $sImgUrl = "http://lorempixel.com/400/200"
    $nMsg = GUIGetMsg()
    Switch $nMsg
         Case $GUI_EVENT_CLOSE
            Exit
         Case $stop
            Exit
         case $start
            InetGet($sImgUrl, $simgdir, 1, 0)
            if fileexists( $simgdir & $filename) then $filename + 1
    EndSwitch
WEnd

I personally would use an INI file in your @ScriptDir to store things such as the last filename used etc..

Use string parsing (if your file names are consistent) to obtain the last file number used... (or better yet, just store it in the ini)

So... This is an example of your INI File

[PreviousVariables]

lastNum=5

fileName=FilenameGoesHere

And this would be the code...

$oldNumber = IniRead(@ScriptDir & $INIFileName, "PreviousVariables", "lastNum", "Unfound")+1
$oldFileNam = IniRead(@ScriptDir & $INIFileName, "PreviousVariables", "fileName", "Unfound")

$NewFileName = $oldFileNam&$oldNumber

Something like that anyway... (Not tested, and free-handed under sleep deprivation... If there's a missing ", my eyes are going cross-eyed lol.

Edit:

Oh, and be sure to INIWrite to the file to update the oldNumber each time.

Thanks Andreu, but I can't get it to work. I do appreciate your assistance though :)

I might just do a for...next and use a batch file rename programs separately to name the files in an orderly way, being that the "for" statement will create the same names again,

Post an example of what you tried, and I'm sure I can fix it for you.

(Note: You do have to create an ini file... Though, using IniWrite trying to write to a ini file that doesn't exist will cause it to create it FOR you.)

if fileexists( $simgdir & $filename) then $filename += 1

 

Sorry mate, just overwrites the file

It's OK, I did a for...next loop, then used a different program to rename them in chronological order. It can start renaming from the last number too, which is handy. It's heaps easier and doesn't take long.

Thanks anyways guys. Have a great night!

      I have a problem with FileOpenDialog using long default filenames ... they always get truncated. 
      For example: 
      "A Long FileName.mpg" as a default would prompt as just "FileName.mpg" (but scrolling left will show it named correctly).
      Does anyone know of a fix for this please (I didn't spot it in a Forum search), or is it one for the bug tracker?
      #include <FileConstants.au3> #include <MsgBoxConstants.au3> Local Const $sMessage = "Hold down Ctrl or Shift to choose multiple files." Local $sFileOpenDialog = FileOpenDialog($sMessage, @WindowsDir & "\", "Images (*.jpg;*.bmp)|Videos (*.avi;*.mpg)", BitOR($FD_FILEMUSTEXIST, $FD_MULTISELECT), "A Long FileName.mpg") Thanks,

      Hey Everyone, I haven't been here in a while and recently picked up my old project. Still an FNG!
      To the point: I want to be able to push the button and either play an mp3, open a file, or open an exe program (all with the same button). The problem is that I don't know how to code for that at "case 1"
              Case 1                                                                                                                                             
                  Local $sRead = IniRead("config.ini", "Config", "One", "Default")                                
                  SoundPlay($sRead, @HotKeyPressed)                                                                     <-------------------------------
                  Run($sRead, @HotKeyPressed)                                                                                 <------------------------------- This 'Run' doesn't work even by itself!
      See code below for layout. If you need more information I will attach more code or answer any questions. Any help is greatly appreciated.
       
      Much Respect,
      Pike
