VB6 program, connecting string-variables wrong result under Win 11

Question

Hi, my Visual Basic 6 programs are running under Win11.

Connecting strings is working properly:

txt = "abc" & "def"

The result is "abcdef"

BUT if I connect two string-variables the second part disappears.

tx1 = "abc"

tx2 = "def"

txt = tx1 & tx2

under Win 11 the result is only "abc".

Is there any other runtime library necessary or is there any other solution?

Answer 1

Probably the real tx1 or tx2 contains some special characters, such as vbNullChar or Chr(0).

Try to fix the strings using something like tx1 = Replace(tx1, vbNullChar, " ").
