More Info Required:

To people who just run into this page :

The history of this shows that IntPtrs for pDot11Ssid and pDesiredBssidList were changed to DOT11_SSID[] and DOT11_LIST[]. Then it should have some kind of explanation about the reason.

I think whether to use IntPtr or DOT11_SSID[] etc should be determined by which one you want, "Marshal" or "UnMarshal".

The rationale behind the change in the history for this is because is that he/she wanted to "unmarshal". However, in functions like WlanConnect(), it is used as an "input". So, it needs to be marshaled. Then I believe they should be IntPtr.

Also, DOT11_SSID[] looks to be wrong. It is to point one "SSID" not a series of SSID.

Also, it would be great if it explains how to marshal ucSSID in DOT11, because the ucSSID is just ANSI string ( without the terminating '\0'. )

>>Here is a simple way to marshal the DOT11_SSID structure. This uses Marshal.AllocHGlobal but you could also use Marshal.StructureToPtr.

    int ssidSize = 4 + 32;
    IntPtr ssidSpace = Marshal.AllocHGlobal(ssidSize);

    byte[] ssidTextBytes = Encoding.ASCII.GetBytes("My SSID");

    Marshal.WriteInt32(ssidSpace, ssidTextBytes.Length);

    for (int i = 0; i < ssidTextBytes.Length; i++)
    Marshal.WriteByte(ssidSpace, 4 + i, ssidTextBytes[i]);

    wcp.pDot11Ssid = ssidSpace;

    ...

    Marshal.FreeHGlobal(ssidSpace);
