    Default disable enable network connections?

    hi all,

    I will like to create a function to disable/enable network connection in my program.I've tried a test code sample but it does not work and I suspect I did not properly included and link the necessary headers and libs..

    Qt Code:
    1. #include <windows.h>
    2. #include <iphlpapi.h>
    3. #include <objbase.h>
    4. #include <netcon.h>
    5. #include <stdio.h>
    6. .....
    7. void disableNIC(char * AdapterName)
    8. {
    9. INetConnectionManager* pNet;
    10. INetConnection* pConn;
    11. IEnumNetConnection* pEnum;
    12. NETCON_PROPERTIES* pProps;
    13. wchar_t Temp[255];
    14. ULONG uCount = 0;
    15.  
    16. swprintf(Temp, L"%S", AdapterName);
    17. CoInitialize(NULL);
    18. CoCreateInstance(CLSID_ConnectionManager, NULL, CLSCTX_SERVER, IID_INetConnectionManager, (void**)&pNet);
    19. //CoCreateInstance(CLSID_ConnectionManager, NULL, CLSCTX_SERVER, __uuidof(INetConnectionManager), (void**)&pNet);
    20. pNet->EnumConnections(NCME_DEFAULT, &pEnum);
    21. ....
    22. ...
    23. }
    To copy to clipboard, switch view to plain text mode 
    it has an error with "undefined referenced to CLSID_ConnectionManager" and "IID_INetConnectionManager",or _uuidof was not declared in this scope.

    I've included objbase.h and netcon.h and have added libole32.a to my Lib directory and I linked it like this: win32:LIBS += -Ld:/Path/Lib -liphlpapi -lole32 -lnetshell
    Is there anything that I've missed and how to solve it?

    Is there any functions in Qt that can be used to disable/enable connections instead?

    Appreciate any advice.

    Hmm... I'm having a deja vu. I though I already answered that question.

    Anyway --- no, Qt has no facilities for managing network interfaces.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.
