MB/s scope grab MS Win

[Simo_na]

Hello
During the operations of file copy carried by MS Windows 10/11 OS is possible to capture the MB/S scope in real time ? if yes ...how do it ?

Try to locate the window control that is responsible for the text you may be able to read it by sending a #WM_GETTEXT message.

I understand what you mean...about...
Find ID of 'copy window'
and then request the 64K
converting the pointer buffer to unicode...

right ?

I thought there was something more immediate way...

Thank you

With window/message functions like FindWindow_(), FindWindowEx_(), EnumWindows_(), SendMessage_(), ...
I dont have an example but you would need to go through all windows/controls and see if it is stored somewhere.
You could also look for it in memory but that is even more complicated.
The easy solution would be to code a custom copy routine and expose what you need.

You won't be able to use #WM_GETTEXT or FindWindow_() with it, because it's not a standard window. I note that WinSpy says the class name for the progress display is "RateChartOverlayWindow", and it seems to be generated on-the-fly. See screenshot below.

However, you can get the speed by doing the math yourself: the window title shows the % complete, so you just repeatedly test this percentage over one second of time and the file's size. The difference would be the MB/s of progress, which would match the speed in the overlay. Just don't ask me how to do the math, lol. I may try when I have some spare time and motivation, if nobody else does it.

It is a standard window and FindWindow_() works!?
The only problem is that the contend of "RateChartOverlayWindow" is drawn, there is just no child window/control holding the MB/s value itself.
On the other hand you can read out the progressbar "msctls_progress32" just fine so no need to read the window title.

I meant that "RateChartOverlayWindow" isn't a standard window (or child window) that can be read with #WM_SETTEXT and FindWindow_().

[Mijikai]

It is a normal window that is registered in the system and can be located through FindWindowEx_() and other window functions.
If there is no text associated with the window #WM_GETTEXT will return nothing.

[BarryG]

You're preaching to the choir... that's what I'm saying (or mean). That the text isn't found using #WM_GETTEXT with a window handle, because it's not a standard window with text to be read. It's drawn.

I thought there was a pointer where peek the value.
i didn't know WinSpy. Thank you
since in my opinion it is a very reliable calculation.
I am trying to write a simple 'backup' application and I would have liked to use it value since using the #FO_COPY...

Or use brute force - https://www.purebasic.fr/english/viewtopic.php?t=77835
But i follow this topic to see which better way is found by the windows experts here.

It is possible to read the information, but the update interval is about 10 seconds, so it seems useless.
See the post.
