Hello!
I add some columns to my TVirtualStringTree. It works correctly.
But, after some time the string has illegal character, for sample, see, please, image_error.png

You'll have to describe a little more exactly what is your problem: The strings change by themselves? Characters are converted when adding them to the tree? Some other thing?

Hello!
I add the string to VST. WOrks correctly.
After sometime I have the string updated with 'illegal' character.
my PTreeData is:
Code: Pascal
[Select]
[+]
[-]
PTreeData
=
^
TTreeData
;
TTreeData
=
record
FHora
,
FVideo
,
FTempo
,
FLogo
,
FIn
,
FOut
,
FTipoNome
,
FNomeCompletoVideo
,
FNomeCompletoLogo
,
FTipoValor
,
FQtde
:
string
;
end
;
Only the string
FNomeCompletoVideo
has illegal character.

You mean it does it by itself? You're not changing/updating the string in your code?
That sounds either like ghosts (in the shell
)* or something in your program is trashing the memory occupied by your records.
* Just in case ... this is a
joke

Hello!
I think 'trashing the memory occupied by your records'. But, How I can to fix it.
Or how I can to locate this 'illegal character. in the my record?
It is always present in 'FNomeCompletoVideo' field.
For sample. I have:
D:\Especial\M_PROG_ESP_REPRISECARNAVAL2017_TRIBUTOAOSAMBA_B0.mov, the correct is D:\Especial\M_PROG_ESP_REPRISECARNAVAL2017_TRIBUTOAOSAMBA_B04.mov
