My code that checks for a change in the number of files isn't working

8 posts in this topic

I have the following code that successfully reads the amount of files in a folder:

$hNumberofFiles = 0
Func _UBound($hNumberofFiles)
    Global $n
    Global $hPath = "T:\"
    $hNumberofFiles = _FileListToArray($hPath, "*.tif", 1)
    For $n=UBound($hNumberofFiles) - 1 to 0 Step -1
        If StringLen($hNumberofFiles[$n]) > 0 Then ExitLoop
        Next
    Return $n
EndFunc
$hFileCount = _UBound($hNumberofFiles)

(I tested it via a MsgBox returning _UBound($hNumberofFiles), which returned the correct number)

However, I can't seem to write a working loop to check for an increase in the number of files:

$hFileCountNew = $hFileCount
MouseClick("", 280, 420, 1, 10) ;Clicks a button to print files to a virtual printer AKA it writes files to a folder
Sleep(700)
While $hFileCountNew <= _UBound($hNumberofFiles) ;If the number of files is still the same, then the report is still loading, so just wait and check again in three seconds
    Sleep(3000)
WEnd

Specifically, the while loop doesn't seem to be working, so the script just sleeps forever/goes idle.

Sorry all, I've solved my own problem by replacing the While Loop with a Do ... Until loop:

Do ;If the number of files is still the same, then the report is still loading, so just wait and check again in three seconds
    Sleep(3000)
Until _UBound($hNumberofFiles) > $hFileCount

@TylerH another option, fewer lines:

#include <File.au3>
#include <MsgBoxConstants.au3>

While 1
    MsgBox($MB_OK, "", _findFileNum())
    Sleep(1000)
WEnd


Func _findFileNum()
    Local $sPath = @DesktopDir & "\Test"
    Local $aFiles = _FileListToArray($sPath, "*.tiff", $FLTA_FILES)
    Return UBound($aFiles) - 1
EndFunc

Wouldn't the While loop have to be after the Func? Otherwise it would be calling an undefined function, no?

@TylerH, no AutoIt does not require your funcs to be above the calling point. In fact, as you look through examples in the help file and on the forum you will see most often they are put at the bottom, with your main body of code calling them.

I can vouch for this!
I wrote something once and all my functions were in the bottom of my script.

By the way, I don't need to create a MsgBox; I just need to store the number of files as a variable so that the rest of my code waits until the number of files != the variable stored at the beginning of the snippet.

It was just an example, you can put the value into a var at the beginning, and then constantly check against it in the While loop

      So I have a loop that keeps reading data from an array and searching it for the same value. If the value is no there it does work then adds the value to the array to prevent it from doing the same work.
      If _ArraySearch($ID,$filearray[$i]) = -1 Then Work.... _ArrayAdd($ID,$filearray[$i]) EndIf This is in a for loop hence $i
      So what is happening is the code works great for several hours. After a period of time _ArraySearch($ID,$filearray[$i]) will result in -1 even if $ID = $filearray. So it ready as if there is no data in the array. Anyone have this problem? 
       
      Also I am just running in using F5 not compiling it and running it if that makes a difference.

      I am reading a CSV file which is tab seperated as below.
      Local $aArray = FileReadToArray($file) And now, I am splitting this main array record wise so that Array contains internally another arrow to represent each row.
      For $i = 0 to (UBound($aArray) - 1) ;MsgBox(0,"",$aArray[$i]) $aArray[$i] = StringSplit(StringStripCR($aArray[$i]), Chr(9),2);Chr(9) for tab ;_ArrayDisplay($aArray[$i]) Next Afther that, _ArrayDIsplay is able to see the individual internal arrays.
      _ArrayDisplay($aArray[1]) But If I try to access the individual element of it as below.It is not showing any result.
      MsgBox(0,"",$aArray[1][1]) Any suggestion, below is the sample csv file.

      Need some help understanding why the ConsoleWrite works inside 2nd For loop but not out side. Between Audit Wiki, Help file , Forum searching (lots of code reading), and YouTube ( shout out to TutsTeach), I have not been able to find the reason why. 
      $sIniPath = "installLog.ini" ; - Get section name $iniSctionNames = IniReadSectionNames($sIniPath) ; - Get Keys and Vaules For $a = 1 to UBound($iniSctionNames) - 1 $keys = IniReadSection($sIniPath , $iniSctionNames[$a]) For $b = 1 to UBound($keys) - 1 $oldSysInfo = IniRead($sIniPath , $iniSctionNames[1], $keys[$b][0], "") $PntIPInfo = IniRead($sIniPath , $iniSctionNames[2], $keys[$b][0], "") $NewPCInfor = IniRead($sIniPath , $iniSctionNames[3], $keys[$b][0], "") ;ConsoleWrite($oldSysInfo & @LF) Next ;ConsoleWrite($oldSysInfo & @LF) Next ConsoleWrite($oldSysInfo) My intention is to use the variables later for Listboxes. Any explanation, forum post links or whatever would help. Sorry also very very new to Autoit.
      Also here's the ini file.
