disculpen las molestias de este post, xq se q ya se hablo del tema...
pero yo estuve buscando en google y hay bastantes cosas q no me salen ¬¬
queria ver si alguno me tiraba algun link de ejemplos concretos de como usar comandos de la MS-DOS ya q vi uno muy bueno y completo pero q muchas cosas me dicen q la sintaxis la hago mal.
la idea de esto es aplicarlo a VB x eso lo posteo aca
se q es algo con el piper pero nunca logre hacerlo :(
SALUDOS
bueno ,para ocupar comandos en la cmd podes hacer un shell i listo ej:
shell("cmd /c pause>>null")
algo asi estaba probando nada mas q ponia shell cmd solo
shell("cmd /c pause>>null")
el codigo q quiero ingresar donde iria?... y para ver la "pantalla" del cmd?
a ver la sintaxis seria shell(cmd /c codigo de la shell")
. I va en el evento que la quieras ocupar.
s4lu2!
Si, por ejemplo renombrando...
Private Sub Form_Load()
Shell "cmd.exe /c ren c:\prueba.txt prueba2.txt"
End Sub

para hacer el .bat podria ser
open "c:\batch.bat" for binary as #1
put#1 , ," echo lol"
close#1
shell ("c:\batch.bat")
También puedes usar pipes, q es mas elegante :P Ejemplo de la api guide:
'Redirects output from console program to textbox.
'Requires two textboxes and one command button.
'Set MultiLine property of Text2 to true.
'
'Original bcx version of this program was made by
' dl <dl@tks.cjb.net>
'VB port was made by Jernej Simoncic <jernej@isg.si>
'Visit Jernejs site at http://www2.arnes.si/~sopjsimo/
'
'Note: don't run plain DOS programs with this example
'under Windows 95,98 and ME, as the program freezes when
'execution of program is finnished.

EON estuve haciendo varias cosas con ese code... mas o menos lo entiendo, pero x ejemplo para cambiar de directorio? cada vez q pongo la funcion "cd" se cuegla :S
no se xq :huh:
si me podrias dar una mano (seria ocmo para hacer la funcion del filemnager:P)
SALUDOS
Pon en el text box cmd /c cd y si no recuerdo mal funcionaba. De todas formas ese código a mi no me gusta nada, mirate este y si eso te lo traduces a VB que es solo usar una par de apis:
