The safearray passed to Javascript:
arr := ComObjArray(VT_VARIANT:=12,3)
arr[0] := "AHK Date = " A_NOWUTC
arr[1] := "AHK Version = " A_AHKVersion
arr[2] := "OS Version = " A_OSVersion
JavaScript display of AHK safearray like any array: arr[0] arr[1] arr[2].
Passing a Javascript array to AHK you get nothing.
Type = ComObjArray
MaxIndex = Large Number (wrong)
SafeArrayGetDim = 68 (wrong)
ComObjType = 200C
Something from Javascript to AHK gets lost in translation.
Anybody know what might be going on with Javascript or AHK maybe WebView2.
Any OBJECT you send to AHK from Javascript comes back empty.
Like Arrays, Html objects (document,body,head, and jQuery objects).
String, integer, float all work OK.
Test SafeArray example:
Code: Select all
#include WebView2.ahk
Show_Data(){
arr := HostObj.oarr
dim := DllCall("oleaut32\SafeArrayGetDim","ptr",ComObjValue(arr))
msgbox "Type = " Type(arr) "`nMaxIndex = " arr.MaxIndex() "`nSafeArrayGetDim = " dim "`nComObjType = " Format("{:X}",ComObjType(arr))
}
