Please make me understand why the behavior of these two arrays is different as shown in these two examples?

14 Mar 2019, 13:39

FIRST EXAMPLE-

I have these values in range a1:a10 -

14_03_19 @11_34_52.PNG
14_03_19 @11_34_52.PNG (4.7 KiB) Viewed 2335 times
Now please look at these codes-

Code: Select all

Xl := ComObjActive("Excel.Application")
	A := {}
	for key, value in Xl.Range("a1:a11")
		MsgBox % key ; shows empty msgbox
In the above codes you can see that i convert the values of range a1:a10 into an array and then i try to show the key which, i think, should be the index number of each value, in msgbox then it shows an empty msgbox.



Now, when i try to show only the value which should be value of each cell like- 500, 600, 900, 100 so on till 900, by following codes then it shows 9 in each msgbox-

Code: Select all

Xl := ComObjActive("Excel.Application")
	A := {}
	for key, value in Xl.Range("a1:a11")
		MsgBox % value ; shows 9 in each msgbox, very strange!!!!
I don't understand why it is happening?


SECOND EXAMPLE-

Code: Select all

arr:= {jone:"smith",sam:"donn",frank:"caine"}
for key,value in arr
	MsgBox % key ; shows jonw, sam and frank
In above codes, it is showing the key of each pair which is - jone, sam and frank


Now when i run following codes-

Code: Select all

arr:= {jone:"smith",sam:"donn",frank:"caine"}
for key,value in arr
	MsgBox % value ; shows smith donn and caine

Then, it shows the value of each pair which is smith, donn and caine.


I am not understanding why each key and value is shown individually in second example, while it is not showing individual key and value of cell in first example?

Please help and guide me..

THANKS A LOT..
I don't normally code as I don't code normally.

You're not dealing with the same types of objects.

One is an AHK object, the other is an Excel object, they work with for-loops differently.

Code: Select all

Xl := ComObjActive("Excel.Application")
for c in Xl.Range("a1:a11")
	MsgBox % c.Value

Thanks dear sinkfaze for your kind reply...

sir, my biggest confusion is that, why the following codes are showing 9 in each msgbox????-

Code: Select all

Xl := ComObjActive("Excel.Application")
	A := {}
	for key, value in Xl.Range("a1:a10")
		MsgBox % value ; shows 9 in each msgbox, very strange!!!!
I think either it should show and empty msgbox or the value of current cell. But, it is not showing both. It does not make any sense showing 9 in each msgbox. Please guide and solve my quarry. Thanks a lot dear sinkfaze....

When you have reply comments.
You'd better take a look at it, even with skimming.
and
You'd better say a brief word, "thanks".

I have commented 3 links
the first one has the clear reason for your asking

...For COM objects, Key contains the value returned by IEnumVARIANT::Next() and Value contains a number which represents its variant type... See ComObjType for a list of type codes.

the second has proper values clearly "9"

Code: Select all

VT_DISPATCH  = 9   ; COM object
I feel like wasted my time

@IMEime
you could have shown him the reason for his asking (not only pointing him to 3 pages)
Key contains the value returned by IEnumVARIANT::Next() and Value contains a number which represents its variant type
and that this is always 9 = COM object

then he had a chance to understand and say "thanks"

and
If you do Not understand it, You do Not represent any kind of appreciation ?
If you say so, that looks very convenient attitude.

The understanding depends on him/her Not me, I have showed the ultimate answer to the question.

You're definitely right. And you shouldn't do it any more.

No more to say, as in SQLite

Thanks a lot dear IMEime.

I am quite beginner so it is quite difficult to understand programming related stuff for me, that's why i asked it again. Anyway thanks you so much...

IMEime has given the specifics, I refrained from doing so because, in this case, it's a lot like going to the doctor and complaining that it hurts when you stab yourself with a knife. It doesn't really matter why it hurts at that point, stop stabbing yourself.
