Returns the last write time for a registry key. (Windows NT or newer)

Syntax:

RegQueryKeyLastWriteTime (handle, subkey-string [,view-flag])

Parameters:

(i) handle handle to a registration database key.

(s) subkey-string a path from the key provided to the desired key, including the "data item name" in square brackets at the end of the key string.

(i) view-flag [optional] controls which registry view the function uses when accessing the Windows registry.
0 - view indicated by the last call to the RegOpenFlags.
32 - use the 32-bit registry view.
64 - use the 64-bit registry view.

Returns:

(s) last write time for a registry key, in YmdHms format.

View-flag

This optional parameter controls which registry view the function uses when accessing the Windows registry. The optional parameter's values can be 32 to use the 32-bit view, 64 to use the 64-bit view, or 0 to use the view indicated by the last call to the RegOpenFlags. The parameter value of 0 can also causes a function to use the WinBatch default 64-bit view, if no call to RegOpenFlags has been made and setting the parameter to 0 is equivalent to omitting the parameter entirely.

Notes:

Using the 32 or 64 values cause these functions to error if a function's subkey parameter contains the string 'wow6432node'.
Setting the parameter to one of the valid values has no effect when running on 32-bit Windows.
The function returns the write time as local time. User IntControl 102 to obtain the write time as UTC time.

Windows Vista/2008 and newer: This function may require an Administrator level account, if it attempts to access protected registry keys: HKEY_LOCAL_MACHINE or HKEY_CLASSES_ROOT.

Example:


lastwritetime = RegQueryKeyLastWriteTime(@REGMACHINE, "Software\Wilson WindowWare")
Message("Last write time:", lastwritetime)
Exit
