#1973 =) I hope this ticket is waterproof...

I don't know why I can't edit posts after I reloggedin. I had another little idea optimizing the last tiny bit of speed... >"C:\Program Files\AutoIt3\SciTE\..\autoit3.exe" /ErrorStdOut "C:\user\BWI\AutoIt\numbers.au3" ----------SHORT TEST---------- Generating random numbers...Done !

I added the default value at index 0. This saves a subtraction by 1 every time. Then I just changed the global Array to have mixed content (strings and integers) which will save another comparison everytime and allows to return the result immediately. I know one shouldn't do this, but for the result is static it doesn't mess anything. There are 59 spaces in my array by the way. This optimization saves a peek over a third (36,3%) instead of a fourth compared to my nested switch-blocks before and a peek over two thirds (68,2%) compared to the linear switch-block of Valuater and FireFox.

Sorry for double posting, but I can't edit my post any more?? I wrote a small new function based on array indexes getting its information from a pre-initialized in-memory static global array with blank entries. It's a fourth faster then my optimized version before... This version before can dynamically be optimized by a recursive function returning the code of the nested switch-Statements. But I won't bet it can get faster than this global array based method. And my new function is the shortest I've ever seen for this. The default-Value 3 results in the first blank array entry, resulting in a return value of -1. >"C:\Program Files\AutoIt3\SciTE\..\autoit3.exe" /ErrorStdOut "C:\user\BWI\AutoIt\numbers.au3" LeftMouse ----------SHORT TEST---------- Generating random numbers...Done !

Hey, I just want to come back to your performance tuning of _GetKeyByHex_SwitchNumber... I optimized it to double speed (maybe a bit more possible). I just cut the test-Switch-Statements into smaller slices (Test-blocks) being tested seperately in smaller Switch-Statements. This can be done one or two steps of smaller slices further to get a few more millis out of it. It's based on the idea to walk recursively through graph trees. Feel free to go this step further into the deep ;-) Theoretically the most speed might be possible when comparing about 2 to 4 times in each nested Switch-block but I don't know AutoIts internal code optimization. This has to be given a try. #Region short test ConsoleWrite(@CRLF & "----------SHORT TEST----------") Global $numtest = 10000 _Test() #EndRegion short test Func _longtest() #Region long test ConsoleWrite(@CRLF & @CRLF & "----------LONG TEST----------") Global $numtest = 300000 _Test() #EndRegion long test EndFunc ;==>_longtest Func _Test() #Region Number ------------------------------ Local $random[$numtest] ConsoleWrite(@CRLF & "Generating random numbers...")

Strangely I didn't have this behaviour until today. I wrote a script that attached to my browser and worked fine just the last few weeks. Today it went nuts so I came along this thread and another one as well. I posted my solution over Might this "patch" probably make it's way into a next release of AutoIt? This funny error only seems to occur on open IE windows not being a TopLevelContainer. I just check out for this.

You can modify your IE.au3 to check whether your IE object is a TopLevelContainer and respond accordingly in Func _IEPropertyGet(ByRef $o_object, $s_property) from line 2669 on: Case $s_property = "hwnd" If Not __IEIsObjType($o_object, "browser") Then __IEErrorNotify("Error", "_IEPropertyGet", "$_IEStatus_InvalidObjectType") Return SetError($_IEStatus_InvalidObjectType, 1, 0) EndIf ;Return SetError($_IEStatus_Success, 0, HWnd($o_object.HWnd())) ;-------------- If $o_object.TopLevelContainer Then Return SetError($_IEStatus_Success, 0, HWnd($o_object.HWnd())) Else Return SetError($_IEStatus_Success, 0, 0) EndIf ;--------------
