Hi all! How to set a text to a window with string length limit.
SetWindoText and WM_SETTEXT doesn't work how I need, they require null-terminated string. I want to know are there alternative functions to work with ACSII strings which sometimes may not to be terminated by zero-byte?

KostX,

Had you meant 'counted' (AKA Pascal/Delphi) strings, like db 13, "Hello, world!"? You may simply poke zero byte right behind the last used byte (provided there is spare byte there) and pass appropriate address to WinAPI (it may not work if that string contains zero byte).

AFAIK Delphi ANSIString and WideString types are made specifically to be compatible with WinAPI (they have length and refcount fields at negative offsets and ensure NUL termination).

The way to do it is dynamically allocate room for the characters you want to set and a terminating null character.
Then copy text, terminate it and then use SetWindowText().
