C# Signature:

[DllImport("Wlanapi.dll",SetLastError=true)]
public static extern uint WlanScan(IntPtr hClientHandle,ref Guid pInterfaceGuid,IntPtr pDot11Ssid,IntPtr pIeData,IntPtr pReserved);

VB Signature:

Declare Function WlanScan Lib "wlanapi.dll" (TODO) As TODO

User-Defined Types:

pDot11Ssid : Pointer to a DOT11_SSID structure.

pIeData : Pointer to a WLAN_RAW_DATA structure.

Notes:

This method just tells the interface to start doing a scan. If you want to get results as they come back, you have to register a callback function. An easier way is to call this method, wait a while, then use WlanGetAvailableNetworkList

Tips & Tricks:

Please add some!

Sample Code:

        Guid g;
        IntPtr ptr = new IntPtr();
        for (int i = 0; i < infoList.dwNumberOfItems; i++)
        {
        g = infoList.InterfaceInfo[i].InterfaceGuid;
        uint resultCode = WlanScan(wlanHndl, ref g, IntPtr.Zero, IntPtr.Zero, IntPtr.Zero);
        if (resultCode != 0)
            return;
        }
        WlanFreeMemory(ptr);
