[TC 11.50b3] Compare by Content: Abort during binary compare

[white]

Compare by content 2 large files.

When using a text compare (Binary not checked), the comparing can be aborted by all the methods you can use to close the window (Esc, Alt+F4, X button) and the Abort button. When comparing is aborted a message box is displayed saying: "User abort!".

When using binary mode to compare the files, you can only use Esc to abort the comparison. I can understand if this is done for speed reasons. What I don't understand is that the Compare button changes into an Abort button you cannot use (although it has the enabled state). If you cannot use the Abort button, I think it would be good to not change the Compare button into an Abort button, but instead disable the Compare button during the comparison. Furthermore, when you abort the comparison by pressing Esc, it aborts quietly without a message box saying: "Use Abort!". This seems inconsistent and confusing.

The help text does not mention an Abort button, nor any information about aborting.

I have tested it now - you can abort via button during the compare phase, e.g. when the first difference is near the end of the files. However, you can only abort with ESC during the phase where the tool counts the number of differences. I will fix that.

I compared 2 files using binary compare of sizes 2.787.952.934 bytes and 1.054.274.743 bytes. I can follow the progress in the status bar. When I press Esc, the progress indicators in the status bar freezes and then (after a variable pause) the status bar becomes empty.

If I click Abort the progress in the status bar keeps going till the end and then the number of differences are shown. If I don't abort, it says:
5 differences found

If I clicked abort, it says higher numbers like:
22 differences found
24 differences found
27 differences found

That's the phase where the tool looks for the number of differences. It starts immediately because the 2 files have different sizes, so they can't be idential.

25.10.24 Fixed: Compare by content, binary mode: The search for the number of differences could only be aborted via ESC, not via button (32/64)

Tested OK using TC 11.50b4 32-bit and 64-bit.
