I tried to implement the code in this topic: Firstly, i have no idea how these lines of code work but meanwhile i noticed that: ; Everytime autoit wants to call a method, get or set a property in a object it needs to go to ; IDispatch::GetIDsFromNames. This is our version of that function, note that by defining this ourselves ; we can fool autoit to believe that the object supports a lot of different properties/methods. Func __IDispatch_GetIDsFromNames($pSelf, $riid, $rgszNames, $cNames, $lcid, $rgDispId) ... EndFunc The problem is i ran into is that some object calls didn't go through IDispatch::GetIDsFromNames. Here is the code to replicate what i'm mentioning: I followed the example in the topic and tried to do the same thing with method .Documents (line 193) and .Open (line 194) but didn't get the same result because .Documents was being passed through __IDispatch_GetIDsFromNames while .Open didn't. $Au3_CallByName = 'Documents' Local $oDoc = $oAppl.Au3_CallByName $Au3_CallByName = 'Open' $oDoc = $oDoc.Au3_CallByName($sFilePath, $bConfirmConversions, $bReadOnly, $bAddToRecentFiles, $sOpenPassword, "", $bRevert, $sWritePassword, "", $iFormat) Console outputs: ==> The requested action with this object has failed.: $oDoc = $oDoc.Au3_CallByName($sFilePath, $bConfirmConversions, $bReadOnly, $bAddToRecentFiles, $sOpenPassword, "", $bRevert, $sWritePassword, "", $iFormat) $oDoc = $oDoc^ ERROR Is there any workarounds to solve this? Thank you!

Trying to figure out how to do CallByName on AutoIt COM objects due to the lack of being able to set properties within an Execute() statement Several Ideas were Tried https://www.autoitscript.com/forum/topic/200129-set-object-properties-with-propertyname-and-value-taken-from-an-array/ I think this is the best; Patching the vtable of IDispatch so we can intercept a Fake function call ($obj.Au3_CallByName) use it like this Local $oDictionary = ObjCreate("Scripting.Dictionary") ; EXAMPLE Au3_CallByname_Init() ; (you can optionally provide a classname here but we patch the main Idispatch interface so really no need) $Au3_CallByName = "Add" ; Method we want to call $oDictionary.Au3_CallByName("Test", "Value") Au3_CallByname_Init(False) ; (Not Strictly Needed unhooked on exit) NOTE: Au3_CallByname_Init() doesn't have to be called at the top of the script, just call it before you need to call by name...
