Problem with Hex and +

[FaridAgl]

$Test = Hex("0x00463FC2", 6)
MsgBox(0, 'It should be: 463FC2', $Test)
MsgBox(0, 'It should be: 463FC3', $Test + 0x1)

How i can sum 463FC2 with 1 and get a result of 463FC3 ?

I played with it for hours, i just can't figure it out. I think it has a simple solution.

Thanks.

Hex()

Returns a string representation of an integer or of a binary type converted to hexadecimal.

Dec()

Returns a numeric representation of a hexadecimal string.

D4RKON3,

Look at what the Help file tells you about Hex:

"Returns a string representation of an integer or of a binary type"

You are passing Hex a Hex number - I am not surprised it is getting confused!

Take a look at this and see if you can see why it works and yours did not:

$Test = 0x00463FC2
MsgBox(0, 'It is: 463FC2', Hex($Test, 6))
MsgBox(0, 'It is: 463FC3', Hex($Test + 0x1, 6))

All clear? Ask again if not.

OK, it's working, but i want the Double Quote around the input variable.

Like this:

$Test =" 0x00463FC2"

D4RKON3,

Then use Execute to evaluate the string first - like this:

$Test = Execute("0x00463FC2")
MsgBox(0, 'It is: 463FC2', Hex($Test, 6))
MsgBox(0, 'It is: 463FC3', Hex($Test + 0x1, 6))

Can't he just Int() it.

Great thanks, exactly what i was searching for.

Can i ask what Execute is doing exactly? Help file didn't explain it much:

"Execute an expression."

Can't he just Int() it.

How?

D4RKON3,

Execute does exactly what it says:

"Returns the value of the evaluated expression"

So you pass it a string representation of a value or a calculation and it tells you the result - the example is pretty clear.

As trancexx has suggested you could also use Int - which also converts the input into a valid number:

$Test = Int("0x00463FC2")
MsgBox(0, 'It is: 463FC2', Hex($Test, 6))
MsgBox(0, 'It is: 463FC3', Hex($Test + 0x1, 6))

All either of these do is get your literal string "0x00463FC2" into a format with which Autoit can do calculations. Remember that AutoIt is not "typed" - in the sense that you do not have to define variables as a string, integer, float, etc. But sometimes you have to force the variable into a certain type so AutoIt chooses the right operation to carry out. It does pretty well on its own, but you have to give it a hand from time to time - particularly when going from strings to numbers.

And thanks again, you are the most amazing guy around here
