- Globals used:
- None
- Functions Called: GetWindowsDirectory, defined in GLOBAL.BAS as follows:i
- Declare Function GetWindowsDirectory Lib "Kernel" (ByVal lpBuffer As String, ByVal nSize As Integer) As Integere
- Explanation: This Function returns a string containing the
- name of the Windows directory. The GetWindowsDirectory
- function call is defined in GLOBAL.BAS (see above)c
- and uses a Windows API call to the Kernel.e
- IMPORTANT NOTE: The string to contain the returned data MUST be fully
- initialized prior to placing data in it, else an Unrecoverable
- Application Error (UAE) will result. This Function initializes the
- string with empty spaces so the result can be trimmed.i
- EVEN SO, the result string has a null char at the end of it which
- must be stripped away manually - RTrim$ or LTrim$ don't strip out
- null chars.
- ANOTHER IMPORTANT NOTE: If your windows directory is in the ROOT, a
- backslash is at the end of the string ("C:\"). If not, there is no
- backslash at the end of the string ("C:\WINDOWS").
- Error trapping is also in this code, giving a STERN WARNING to the user.
- If this procedure fails, your system is mightily confused.
- linefeed for message formatting-
- The length is arbitrary, but MUST be defined.-
- Initialize the full string to SPACES. The full length of the-
- string MUST be present before making the function call, else UAE!-
