Robinson1 2 Posted November 30, 2013 Is there an other way like this: dim $myStringBuff=StringBuff(3) MsgBox(0, "StringBuff(5)=", $myStringBuff) ;------------------------------------------------- Func StringBuff( $size, $FillChar="0") Local $StringBuffer For $i = 1 To $size $StringBuffer = $StringBuffer & $FillChar Next Return $StringBuffer EndFunc to easily create a String in Autoit? Especially $StringBuffer = $StringBuffer & $FillChar is a really bad way to do so regarding the performance. (each time in the Loop a new string is created and the old one is discarded) Maybe something like this Local $StringBuffer[$size] For $i = 1 To $size $StringBuffer[$i] = $FillChar Next Return $StringBuffer ^-Sample Doesn't work ...or Local $StringBuffer For $i = 1 To $size _StringAppend($StringBuffer, $FillChar) Next Return $StringBuffer were '_StringAppend()' is some Interpreter optimised version that does some kind of redim to $StringBuffer and then append $FillChar Share this post Link to post Share on other sites
Melba23 2,861 Posted November 30, 2013 Robinson1,Have you come across _StringRepeat in the Help file? if not, I suggest taking a look.

Robinson1 2 Posted November 30, 2013 (edited) Robinson1, Have you come across _StringRepeat in the Help file? if not, I suggest taking a look. M23 Wow cool _StringRepeat that's it. Thanks. I actually looked how it's implementated: Func _StringRepeat($sString, $iRepeatCount) ;... For $iCount = 1 To $iRepeatCount $sResult &= $sString Next Return $sResult EndFunc So the core part is this: $sResult &= $sString Hmm I guess the operator '&=' on a string is already linked like to some kinda StringConcat. Anyway $sResult &= $sString is more nice than $sResult = $sResult & $sString. ...so I'll use that construct or _StringRepeat in future.

Melba23 2,861 Posted November 30, 2013 Robinson1,The function in the Beta version is rather more advanced - and much quicker I am told: Func _StringRepeat($sString, $iRepeatCount) ; Casting Int() takes care of String/Int, Numbers. $iRepeatCount = Int($iRepeatCount) ; Zero is a valid repeat integer. If StringLen($sString) < 1 Or $iRepeatCount < 0 Then Return SetError(1, 0, "") Local $sResult = "" While $iRepeatCount > 1 If BitAND($iRepeatCount, 1) Then $sResult &= $sString $sString &= $sString $iRepeatCount = BitShift($iRepeatCount, 1) WEnd Return $sString & $sResult EndFunc ;==>_StringRepeatM23 Any of my own code posted anywhere on the forum is available for use by others without any restriction of any kind Open spoiler to see my UDFs: Spoiler ArrayMultiColSort ---- Sort arrays on multiple columnsChooseFileFolder ---- Single and multiple selections from specified path treeview listingDate_Time_Convert -- Easily convert date/time formats, including the language usedExtMsgBox --------- A highly customisable replacement for MsgBoxGUIExtender -------- Extend and retract multiple sections within a GUIGUIFrame ---------- Subdivide GUIs into many adjustable framesGUIListViewEx ------- Insert, delete, move, drag, sort, edit and colour ListView itemsGUITreeViewEx ------ Check/clear parent and child checkboxes in a TreeViewMarquee ----------- Scrolling tickertape GUIsNoFocusLines ------- Remove the dotted focus lines from buttons, sliders, radios and checkboxesNotify ------------- Small notifications on the edge of the displayScrollbars ----------Automatically sized scrollbars with a single commandStringSize ---------- Automatically size controls to fit textToast -------------- Small GUIs which pop out of the notification area Share this post Link to post Share on other sites
Robinson1 2 Posted November 30, 2013 I see it's blowing up da string exponentially now. Nice idea. I'll keep that idea for other languages. Its a little hard to see on the first glance - Maybe that will be a little better readable Func _StringRepeat($sString, $iRepeatCount) ; Casting Int() takes care of String/Int, Numbers. $iRepeatCount = Int($iRepeatCount) ; Zero is a valid repeat integer. If (StringLen($sString) < 1) Or _ ($iRepeatCount < 0) Then _ Return SetError(1, 0, "") ; Blow up string exponentially Local $sResult = "" While $iRepeatCount > 1 ; when RepeatCount is uneven; store rest in $sResult If mod($iRepeatCount, 2) Then $sResult &= $sString EndIf ; Concat string exponentially $sString &= $sString ; Next $iRepeatCount = int($iRepeatCount / 2) WEnd Return $sString & $sResult EndFunc ;==>_StringRepeat ^-I also took out that bit crafting stuff even if that might tiny slow down the function.
