Ei alguem sabe me dizer pq esse codigo compila certinho com o c++builder4 e quando eu compilo com o c++builder6 da erro ?

Se alguem souber o q tah de errado me avissa vai quebra um galo

valeu

Cara, ele não cria um .jpg e sim um .bmp, tanto que o Printscreen fica com incriveis 3mb.

O certo é depois da rotina de criar um .bmp, criar outra que converta pra .jpg, mas isso é tenso de fazer no Dev-C++, só fica tranquilo de fazer no Visual C++, pq ele usa bibliotecas do windows pra fazer a conversão e tudo mais...

Bitcoder, procura o pacote SDK da Microsoft, nem todos os compiladores conseguem usar as bibliotecas do GDI+ (que eh o que se usa em windows pra criar e converter imagens, na maioria das vezes), então você tem que baxar e instalar o SDK e fazer seu compilador procurar os includes e as libs na pasta onde vc instalou ele...

Dá trabalho, cara, recomendo mto que você use simplesmente o Visual C++ e seja feliz XD
