cotax Posted May 9, 2010 Share Posted May 9, 2010 Hi, I was testing and trying to make an array, split it and use the output for something else. Now i've made this script (see below) Wanted to check trough $Array[0] (what shows u how much entries there are after splitting) tried alot of combinations but dint work becouse it exceeds the array entries becouse of: $Array[$i+1]. Was getting crazy til i tried to use: if $test2 < $Array[0]+1 worked great till it exceeded the array entry and giving an error so i made and "extra entry" to try if it worked but it worked strange becouse he was displaying all entries and after that an error becouse it exceeded the entry limit. so i removed that one. Next i placed a -1 (dunno why i did this, did/tried alot of thing) at: For $i = $Array[1] To $Array[0]-1 and now my script works great, it shows me the things i splitted without giving any errors. my question is how is this possible? can anyone explain it to me? $List = "banaan-appel-noot-mies-extra entry" $Array = StringSplit($List,'-') ;split $List at - For $i = $Array[1] To $Array[0]-1 ;gives $i an array number (i putted a -1 here else the script doesnt work) $test2 = $Array[$i+1] ;counts +1 at the $i number if $test2 < $Array[0] Then ;if $test is below max array entry then give a message MsgBox(0,"test array", $test2 ) ;at this place, comes the script where i am going to use the output EndIf Next Link to comment Share on other sites More sharing options...
jchd Posted May 9, 2010 Share Posted May 9, 2010 What's wrong is your usage or the loop (For) variable. It has to be numeric. Read again the help file for For. Then , what is the purpose of your loop? $test2 = $Array[$i+1] will assign a string to $test2, so it won't count anything. Re-read the AutoIt datatypes and variables chapters of the helpfile. Local $List = "banaan-appel-noot-mies-extra entry" Local $Array = StringSplit($List, '-') ;split $List at - For $i = 1 To $Array[0] ConsoleWrite($Array[$i] & @LF) Next This wonderful site allows debugging and testing regular expressions (many flavors available).

cotax Posted May 9, 2010 Author Share Posted May 9, 2010 there is nothing wrong with my script. it works great... example of what i am going to do: $List = "alcohol 120-fraps-everest-ftd-autoit v3" $Array = StringSplit($List,'-') For $i = $Array[1] To $Array[0]-1 $test2 = $Array[$i+1] if $test2 < $Array[0] Then RunWait($test2 &"\Installer.exe") ;this will be the scrip i gonna use on this place EndIf Next Link to comment Share on other sites More sharing options...
jchd Posted May 9, 2010 Share Posted May 9, 2010 It only works by chance and you really should listen to advises. For $i = $Array[1] ... This part is already wrong. For deals with a numeric variable, so it converts $Array[1] to a number. $Array[1] contains "alcohol 120" and Number() return 0. So you're doing: For $i = 0 ... but the array returned by StringSplit contains the number of split entries. Hence you're going to process $Array[0], which in your particular case equals 5... Then, the last element in $Array is $Array[5] and contains "autoit v3", but since you stop the loop at $Array[0]-1 (equals 4), you're only process this entry as you process element $i+1, once assigned (uselessly) to $test2. That's not all: the test If $test2 < $Array[0] is always true: $test2 is a substring and $Array[0] a number, so AutoIt does: If Number($test2) < 5, which is: If 0 < 5, which is always true. All in all, you've accumulated errors which more or less compensate, but that's only by chance. Your script should be: $List = "alcohol 120-fraps-everest-ftd-autoit v3" $Array = StringSplit($List,'-') For $i = 1 To $Array[0] RunWait($Array[$i] & "\Installer.exe") ;this will be the script I gonna use on this place Next If you want/need to produce more complex scripts, then you definitely should read a good array tutorial.

cotax Posted May 9, 2010 Author Share Posted May 9, 2010 It only works by chance and you really should listen to advises.i do and wanna do else i dint ask for it in the beginning i dont know how to call the array, when i putted an msg box in it it only showed me numbers. thats why i made something like this script. the key is $Array[$i], but i dint know how to get the entries out of the array now i know how to call the enrties the right way with $Array[$i]. And offcourse this will make things alot easier for me now For $i = $Array[1] ... This part is already wrong. For deals with a numeric variable, so it converts $Array[1] to a number. $Array[1] contains "alcohol 120" and Number() return 0For $i = $Array[1] To $Array[0] is not wrong (think its not) why? u cal the array with: $Array[1] will show u alcohol 120 etc... $Array[2] ... $Array[3] ... $Array[4] ... $Array[5] ... so if u only need lets say the 3th split then i can call it like $Array[3] then it shows me everest so if i use: For $i = $Array[1] To $Array[0] it wil be the same as: For $i = 1 To $Array[0] or am i wrong here?

jchd Posted May 9, 2010 Share Posted May 9, 2010 so if i use: For $i = $Array[1] To $Array[0] it wil be the same as: For $i = 1 To $Array[0] Not at all. $Array[1] is text, as explained earlier. For expect a number, so it convert your text to a number,giving 0. But you don't want to start indexing at 0, since $Arrray[0] contains the number of text elements in the rest of the array.. For will not iterate thru the contents of the array, it will iterate a numeric variable (integer in most cases) which you use to access the array elements by indexing. Please make yourself a favor and read helpfile datatypes and variables chapter, then read the rest! This wonderful site allows debugging and testing regular expressions (many flavors available).
