[英]How do I know an Excel application property has changed (Ex: UseSystemSeparator) or a custom Tab have been selected?
[英]How do I know my application has not been added to the firewall?
我使用netsh将我的应用程序添加到防火墙,如下所示。 在将其添加到防火墙之前,如何知道应用程序尚未添加到防火墙? 因为我不想反复将我的应用程序添加到防火墙。
ProcessStartInfo info = null;
try
{
using (Process proc = new Process())
{
string productAssembly = new Uri(Path.GetDirectoryName(Assembly.GetExecutingAssembly().CodeBase)).LocalPath + "\\" + this.ProductName + ".exe";
string args = string.Format(CultureInfo.InvariantCulture, "advfirewall firewall add rule name=\"{0}\" dir=in action=allow program=\"{1}\" enable=yes", this.ProductName, productAssembly);
info = new ProcessStartInfo("netsh", args);
proc.StartInfo = info;
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.CreateNoWindow = true;
proc.StartInfo.RedirectStandardOutput = false;
proc.Start();
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
TheGreatCO,谢谢。 我已经尝试过它并且有效。
private bool isFirewallEnabled()
{
ProcessStartInfo info = null;
string result = string.Empty;
try
{
using (Process proc = new Process())
{
string args = string.Format(CultureInfo.InvariantCulture, "advfirewall firewall show rule name=\"{0}\"", this.ProductName);
info = new ProcessStartInfo("netsh", args);
proc.StartInfo = info;
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.CreateNoWindow = true;
proc.StartInfo.RedirectStandardOutput = true;
proc.Start();
while ((result = proc.StandardOutput.ReadLine()) != null)
{
if (result.Replace(" ", String.Empty) == "Enabled:Yes")
{
return true;
}
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
return false;
}
