Hello,

You are actually capturing nothing ("[]") while you really need to capture variables either by reference ("&") or by copy ("=").
(Note that in both cases (whether you use [&] or [=]) the "this" pointer will be automatically captured, so you'll have access to AnaForm class' members such as butonlar[] array.):

Also, you really don't need a (empty) parameter list here. It can be omitted.

butonlar[i]<<[&]{ btnDuzenle(&butonlar[i]); }; // this should work, since butonlar[] is a member of AnaForm class.
butonlar[i]<<[=]{ btnDuzenle(&butonlar[i]); }; // this should work too.

// And you can also get rid of the member function AnaForm::btnDuzenle()

butonlar[i]<<[=]{ butonlar[i].SetLabel("X"); }; // this is IMO a more elegant solution in such  simple cases (given your example code).

Best regards,
Oblivion
