Search edit of length >64K is odd

[therube]

The Search edit will stop displaying text when the length is greater than 65535 characters, but the search will still function correctly.

That's odd when it occurs.
Might not be apparent just what is going on in such circumstances.

It's a limitation with the Windows edit control.

I will need to implement my own edit control...

My point was more that it is just "blank".

Maybe if there were some sort of "message"; "overflow", "too long", ... at least it might be more apparent that actual results are being returned (even if you might not necessarily know what they are based on .)

Note that the window title does show some part of the search line.

The limitation varies from different Windows versions, with no easy way to know the limitation.

I could render the text myself when the length is over 4096 characters.

The Window caption is truncated to 255 characters.
