Bom, andei pesquisando na NET e achei um modo de enviar arquivos via FTP(Usando o wininet.dll)
Consegui enviar arquivos tranquilamente mas tem um problema... eu queria que ele não apagase o conteudo do arquivo que já esta dentro do FTP entende? tpw eu envio um .txt com o nome primeiro.txt. dentro desse arquivo está escrito 123 depois de um tempo eu altero esse arquivo e digito 456 .. quando eu olhar no site só vai tar 456.

Olá :D
Bom, andei pesquisando na NET e achei um modo de enviar arquivos via FTP(Usando o wininet.dll)
Consegui enviar arquivos tranquilamente mas tem um problema... eu queria que ele não apagase o conteudo do arquivo que já esta dentro do FTP entende? tpw eu envio um .txt com o nome primeiro.txt. dentro desse arquivo está escrito 123 depois de um tempo eu altero esse arquivo e digito 456 .. quando eu olhar no site só vai tar 456.
O módulo
Então eu uso:
MMtouchFtpFile("ftp.servidor.com.br", "meu_usuario", "minha_senha", "arquivo_remoto,txt")
Touch file = Toque no arquivo? Só que ele apaga o arquivo e manda um em branco..
e usando o putfile ele substitui toda vez que é enviado..
alguém pode me ajudar? Outra Duvida rapida é sobre o Inet(pesquisei algumas coisas aqui sobre isso e vo estudar depois) O arquivo Msinet.ocx é padrão do WinXP ou vou precisar baixa-lo pra usa? É que eu não tenho certeza se baixei esse ocx ou já tinha ^^
É isso.
Obrigado pela atenção,
t+
