a few bugs?

06 Dec 2018, 12:39

bug 1
I'm not sure if the bug exists in AHK v1.1. Negative StartingPos for InStr:

Code: Select all

msgbox(InStr("4111.3",".",,-1)) ;says [b]5[/b] instead of [b]2[/b]
;If StartingPos is negative, the search is conducted in reverse (right-to-left),
;	starting at that position from the right. For example, -1 starts at the last character.
;	If StartingPos is 0 or beyond the length of Haystack, 0 is returned.
bug 2
The bug might be related to Windows though (tested with Win7 x64 SP1). I have a scene with 2 ListView GUI controls.
Everything works as expected until I try to assign a custom background for ListView: lv.Opt(backgroundNNN).
After that the old ListView focus position is not redrawn with custom background automatically until the time the old ListView rebuilt (lv.Delete(), lv.Insert(,,,,))

screenshot: Old ListView focus position with default background instead of set one (grey).

simplified code snippet:

Code: Select all

g:=GuiCreate()
n:=15
f:=g.Add("ListView","w450 r" n " backgroundgray", "C1|C2|C3|C4|C5")
	loop(n)
		i:=A_Index, f.Insert(i,,"", "val " i, "val " i, "val " i, "val " i, "val " i)
f:=g.Add("ListView","w450 r" n " backgroundgray", "C1|C2|C3|C4|C5")
	Loop(n)
		i:=A_Index, f.Insert(i,,"", "val " i, "val " i, "val " i, "val " i, "val " i)
g.OnEvent("Close", () => ExitApp()), g.OnEvent("Escape", () => ExitApp())
g.Show()

Image
screenshot: and in my ahk v2 script it goes even further showing 2 focused (in blue) lines in 2 LVs (old and select one) with lv.Modify(row, "Select") (not as expected). :D

bug 1
The missing link:
Regardless of the value of StartingPos, the return value is always relative to the first character of Haystack. For example, the position of "abc" in "123abc789" is always 4.

Ah I see. :D Thank u for quick reply!

I updated 1st post with the snippet and new screenshot. Old ListView focus position is redrawn with default background instead of set one.

I have moved this from the v2 forums until we can verify that the functionality in question are actually bugs.

not a bot. trade tool. sort of. ;)

btw the issue (bug or feature?) with AHK being no respecter of the custom background continues with custom foreground colors as well.
