Oh! Thanks Titan .. I forgot about that topic completely..



Edit: Thanks for that wikipedia link too ..

Thanks, Titan, for this starter.
A simple example: 16bit unsigned integers can go from 0 to 65535.
16bit signed integers go from -32768 to 32767 (IIRC).
So a number above 32767 used as signed number is seen as negative. Take its absolute value or cast it to a bigger number, and you have a wrong number!
It can make subtle bugs...

An explanation one step deeper: In computers machine words contain a number (n) of bits: b[0], b[1]…b[n-1], which are ON or OFF. When operations are performed on these words, they are interpreted as characters, integers, decimal numbers, addresses, etc. When they are interpreted as integers, there are two common conventions:
- Unsigned integers. Bits are interpreted as 0/1 binary digits: b[i] * 2**i, so a bit sequence of 1010 means 2**3+2**1 = 10. Number = SUM(i=0..n-1, b[i] * 2**i). The smallest unsigned integer is 0, the largest one is 1+2+4+…=2**n - 1.
- Two's complement signed integers. Bits are interpreted as 0/1 binary digits except the leftmost one b[n-1], which is interpreted as a negative binary digit, -b[n-1]*2**(n-1): Number = SUM(i=0..n-2, b[i] * 2**i) - b[n-1] * 2**(n-1). A bit sequence 10001100 interpreted as 8-bit signed number is -2**7 + 2**3 + 2**2 = -128+8+4 = -116. The smallest signed integer is "1000…" = -2**(n-1), the largest one is "0111…" = 2**(n-1) - 1.

When you choose INT or UINT (or CHAR, or FLOAT…), you tell the computer how to interpret the bunch of bits in the corresponding machine word.

Thank you Sir.

Really nice!

I move around a lot of large files in my backup scripts and what annoys me is that a Progess looks too tacky and Gui requires more code so I never bothered to do either, I wait for the script to exit or use MsgBox. Your function makes things much easier and meets all my needs - cancel button, force overwright etc. so thank you.

Thanks to all!

Back in FEB 2005 when I had bought my Digital Camera, I was using DOS BAT to move files from the memory stick. When I googled for a tool that could do BATCH in Windows, first I found the WinBatch ( Not free! ) and then further search led me to AutoHotkey ( I heard about AutoIt only from AHK doc and then from our forum! )

Actually I wanted to go after CopyFileEx / MoveFileEx after the much awaited Callback facility was implemented while ShFileOperation() function was always there

ShFileOperation() is a good candidate for StdLib as the basic flags should work even with Windows 95. But documenting it with easy-to-understand language is tougher than the wrapper itself!

Thanks again

Nice work Skan...very useful contributions

Hi Skan and Forum,

Thanks for the ShellFileOperation funtion is great!!!

Question:
Is there a way to determinate the ahk_id of the window Coping... Moving... etc in Win Explorer that show the progress before (or after but I rather have it before) ShellFileOperation is called.

At the moment I'm using a Hotkey over the coping... Win and I gt the ID store on ""UNDER_HOTKEY_WIN_ID" on My Script

I like to apply the following subroutine to that win whithout clicking on it:
