Learners Question...

[WhiteTiger]

How do you find out what parameters there are in an API call...you constantly see things like

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

But how do you guys know that,

Private Const VK_MENU = &H12
Private Const VK_SNAPSHOT = &H2C
Private Const KEYEVENTF_KEYUP = &H2
Public Const SnapScreen = &H0
Public Const SnapWindow = &H1

should equal what it does for doing certian things?...

Is there an API resource that you can look up examples on how all the API calls are used and stuff like that? Regards,

Look in the API viewer. That should have some API calls and their parameters there.

For the other ones that are not there, the MSDN library should have them. If u dont have the MSDN library, go to msdn.microsoft.com.

The constants that you see are also in the API viewer...well some of them. But all of them can be found in the MSDN library.

Hope that helps.

P.S. Insanity is only BAD to those who are not insane.
