sending command F5

[Marcelo Velasquez]

As I do for through an application in VB, to change the attributes of a file for occult or system and to apply immediately for when the user opens the explorer he doesn't get to see, how to send of the command F5

if i understand u right, to simulate the keystroke F5, I think one way to do this would be to use the keybd_event API.
The Virtual Key code to pass to this function for F5 is &H74.
I would probably make a constant like:

Private Const VK_F5 = &H74

I've got the declaration of the keybd_event in C++ and VB.
If you need the declaration, just lemme know which language.

You really understood!!!, As I make this, if you can send a piece of the code I thank

I am in advance grateful

Sure, here it is in VB (cuz thats what i use):

Private Declare Sub keybd_event Lib "user32" _
(ByVal bVk As Byte, _
ByVal bScan As Byte, _
ByVal dwFlags As Long, _
ByVal dwExtraInfo As Long)

'bvk - the virtual key code to be sent to the kb buffer
'bScan - hardware scan code.. just always set this to 0
'dwFlags - xtra info about the event
'dwExtraInfo - just set this to 0 too

'So, say u want to pass the F5 key, in a sub or function 'somewhere the code would be:

Private Const VK_F5 = &H74
Private Const KEYEVENTF_KEYUP = &H2

keybd_event VK_F5, 0, 0, 0
keybd_event VK_F5, 0, KEYEVENTF_KEYUP, 0

'U have to run the command twice like that cuz first time 'is pressing the key down and the second time is releasing 'it. Also sometimes when i pass keys i have to make the 'program sleep for a couple seconds to give the form a 'chance to come up.
'Hope this helps...
