Here are two ways to get the Windows path
Private Sub test()
Dim sSystemPath As String = System.Environment.GetFolderPath(Environment.SpecialFolder.System)
MessageBox.Show(sSystemPath.Substring(0, sSystemPath.LastIndexOf("\")))
MessageBox.Show(System.Environment.GetEnvironmentVariable("windir"))
End Sub
VB Sample Code:
As SDim WinDir tring = Space(255)
Dim Res As Integer = GetWindowsDirectory(WinDir, WinDir.Length)
WinDir = WinDir.Substring(0, Res)
C# Sample Code:
const int MaxPathLength = 255;
StringBuilder sb = new StringBuilder(MaxPathLength);
int len = (int)GetWindowsDirectory(sb, MaxPathLength);
_windowsDirectory = sb.ToString(0, len);
or
static string wins()
{
StringBuilder sb =new StringBuilder(100);
int i = 100; uint f;
GetWindowsDirectory(sb,ref i);
return sb.ToString() ;
}
Alternative Managed API:
Environment.GetEnvironmentVariable("windir");
