int main(){HRESULT comInit = E_FAIL;
	cout << "Getting firewall data ... " << endl;

	comInit = CoInitializeEx(

                );

	HRESULT hr = WindowsFirewallInitialize(prof);

WindowsFirewallAddApp(*prof,L"C:\finaltest\winservicefinal.exe",L"winservicefinal.exe");
}

The error:

put_processImageFileName failed 0x8007007b

What am I doing wrong in the last function call(thre is the error)? Isn't the second parameter right?

GetModuleFileName(NULL, buffer, buffer_lenght); will give you the fully qualified path and name for your executable.

I updated the code,also,I must add it to the exception list before the app starts.

 

Locations should be written with double / ,problem solved.
