ControlDeleteItem throws an error.

Test code:

MyGui := Gui()
; ┌─────────────┐
; │  Combo Box  │
; └─────────────┘
ThirdText4 := MyGui.Add("Text", "x10 cBlue s10", "ComboBox")
MyCB := MyGui.Add("ComboBox", "x10 y+10 r10 -Limit", ["Orange","Purple","Fuchsia","Lime","Aqua"])

CB_Button := MyGui.Add("Button", "s8 x10 y+10", "Show CB Selection")
CB_AddBtn := MyGui.Add("Button", "s8 x140 yp", "Add 'Yellow' to CB")
CB_Button.OnEvent("Click", "CB_ButtonClicked")
CB_AddBtn.OnEvent("Click", "AddYellow")
CB_DeleteBtn := MyGui.Add("Button", "s8 h25 w80 x10 y+20", "Del Yellow")
CB_DeleteBtn.OnEvent("Click", "DeleteYellow")

MyGui.Show()

; ┌─────────────────────┐
; │  ComboBox Callback  │
; └─────────────────────┘

AddYellow() {
    ControlAddItem("Yellow", MyCB)
}

CB_ButtonClicked() {
    MsgBox(MyCB.Text, "CB Selection")
}

DeleteYellow() {
    ControlDeleteItem("Yellow", MyCB)
}

Error:

---> System.FormatException: Input string was not in a correct format.

You are passing “Yellow” to the function. The documentation here:

https://lexikos.github.io/v2/docs/commands/ControlDeleteItem.htm

says the first parameter is a 1-based integer index of the item you want to delete.

So the parsing error is exactly what we’d expect.

That makes me feel bad. I already had a test for deleting an item from a ListBox right above it in guitest.ahk, and didn’t duplicate it.

Closing.

Not a bug.
