Ultimately, I would like to combine the results from the following onto one sheet:

1) CreateObject("WScript.Shell").Run "cmd /c netsh wlan show networks mode=BSSID" & _
"|clip""", 0, True
specifically:
SSID, Networktype, Authentication, Encryption, MAC Address (BSSID), Signal level, Radiotype, Band, & Channel ... I have the code to do this :)

2) Data scraped from WLAN_AVAILABLE_NETWORK
specifically:
uNumberOfBssids, uNumberOfPhyTypes, dot11PhyTypes

3) Data scraped from WLAN_BSS_ENTRY
specifically:
lRssi, uLinkQuality, usBeaconPeriod, ullTimestamp


The code I have for getting the data from WLAN_AVAILABLE_NETWORK works perfectly.

The problems I encounter is when I try getting the data from WLAN_BSS_ENTRY.

The problems seem to be multiple.
The gathering of data from WLAN_BSS_ENTRY only occasionally works for the first row of data, most of the time it produces 'garbage' info. All additional rows seem to result in 'garbage' info.

I would tend to think that the issue is a memory pointer issue not being incremented properly.

I have also noticed that the WLAN_AVAILABLE_NETWORK section that works perfectly, doesn't 'jive' with the results from WLAN_BSS_ENTRY ... ie. The SSID's aren't matched up.


Any help would be most appreciated. Probably serves me right for delving into this area of API's and such that I am not used to dealing with.

Perhaps someone such as @Jaafar Tribak or others that are wise to this approach of 'scraping' data could assist.

The following is the code I am currently trying to use to scrape the data from WLAN_AVAILABLE_NETWORK & WLAN_BSS_ENTRY:

This version atttempts to handle a situation from one tester that 'Band' data is not included in the:

netsh wlan show networks mode=BSSID results.

To compensate for that situation, I added code to 'skip' the code that would normally handle the 'Band' data & I just checked the channel # & set the 'Band' according to that.

Again, I am open to all comments.

You can convert a byte array to a string by simply assigning the byte array to a string variable:

VBA Code:
Private Function ByteToString(Data() As Byte) As String

    Dim TempString As String
    TempString = Data
    If InStr(TempString, Chr(0)) Then
        ByteToString = Left(TempString, InStr(TempString, Chr(0)) - 1)
    Else
        ByteToString = TempString
    End If
   
End Function

Even this is probably a bit unnecessary.

As for the balance of it, my thoughts are more stylistic (e.g., you could split the resulting string into an array by line, and then cycle through the resulting elements, and split again (as required) by " : ", I suppose). Also, there are methods of retrieving the output of a shelled command without having to rely on the clipboard (or APIs).

Hope that helps. :-)

Ok, I got rid of the ByteToString function and I changed:
VBA Code:
                WLAN_BSS_ENTRY_Array(ArrayRow, 1) = ByteToStr(udtBSS.dot11Ssid.ucSSID)  '       Save the SSID to WLAN_BSS_ENTRY_Array

to the following:
VBA Code:
                WLAN_BSS_ENTRY_Array(ArrayRow, 1) = udtBSS.dot11Ssid.ucSSID             '       Save the SSID to WLAN_BSS_ENTRY_Array
'
                If InStr(WLAN_BSS_ENTRY_Array(ArrayRow, 1), Chr(0)) Then                '           If null characters are found in the SSID then ...
                    WLAN_BSS_ENTRY_Array(ArrayRow, 1) = Left$(WLAN_BSS_ENTRY_Array(ArrayRow, 1), _
                            InStr(WLAN_BSS_ENTRY_Array(ArrayRow, 1), Chr(0)) - 1)       '               Truncate the SSID string at the first null character
                End If

For the section of code that was using the clipboard with the shelled command, I changed:
VBA Code:
' Run a command in the Command Prompt to retrieve information about available wireless networks in BSSID mode and save the results to the clipboard
    CreateObject("WScript.Shell").Run "cmd /c netsh wlan show networks mode=BSSID" & _
            "|clip""", 0, True                                                          ' Save results of the cmdline to the clipboard
'
' Create an object to interact with the clipboard and retrieve the results of the command
    With CreateObject("New:{1C3B4210-F441-11CE-B9EA-00AA006B1A69}")
        .GetFromClipboard                                                               '   Get the output from the clipboard
        AvailableWirelessNetworksData = .GetText(1)                                     '   Save the clipboard contents to AvailableWirelessNetworksData
    End With
'
' Clear the clipboard by opening, emptying, and closing it
    OpenClipboard (0&): EmptyClipboard: CloseClipboard                                  ' Erase the contents that were saved to the clipboard

to the following:
VBA Code:
    AvailableWirelessNetworksData = CreateObject("WScript.Shell").Exec( _
            "cmd /c netsh wlan show networks mode=BSSID").StdOut.ReadAll                ' Save output of command from the standard output stream to AvailableWirelessNetworksData

That allowed me to get rid of the API's for the clipboard also.


Other suggestions?

FYI @johnnyL
.
This didn't work for me. Looks like it needs elevated rights. Nothing is placed in the clipboard.
VBA Code:
CreateObject("WScript.Shell").Run "cmd /c netsh wlan show networks mode=BSSID" & "|clip""", 0, True

This however did work but is there a way to keep the cmd prompt window hidden like with the Run Method?
VBA Code:
     AvailableWirelessNetworksData = CreateObject("WScript.Shell").Exec( _
            "netsh wlan show networks mode=BSSID").StdOut.ReadAll

But the code still breaks at this line :
VBA Code:
        ResultArray(ArrayRow, 8) = Mid$(AvailableWirelessNetworksData, IncrementalStartPosition, _
                IncrementalEndPosition - IncrementalStartPosition)                      '   Save the Radiotype into the ResultArray
Runtime error 5 (Invalid procedure call or argument)

Edit:
IncrementalEndPosition returns 0
It seems the issue is in the preceeding line:
Code:
IncrementalEndPosition = InStr(IncrementalStartPosition, _
                AvailableWirelessNetworksData, "Band")

Thank you for responding again @Jaafar Tribak, I will try to address your issues.

1) Nothing being placed in the clipboard? That line of code should put the results into the Windows clipboard, not the Excel clipboard.

2) Is there a way to keep the cmd prompt window hidden like with the Run Method? The 'Run' method does allow for hidden window, but from what I read you can't directly read the results. You would need to copy the results to a temp file, for example, read results from that temp file & then delete the temp file.

3) You are the second person that has reported that the returned data does not contain any 'Band' data. I am not sure if that is the fault of the adaptor being used or if it is a windows version issue, I would assume that it is adaptor related. Have you tried the code from post #53? I already addressed this issue with the code in post #53. It also contains the code to 'Calculate' the band in the cases that the received data does not contain any 'Band' data.

Here is the relevant section of code in post #53 that I am referring to:
VBA Code:
' Save the Band
        If InStr(IncrementalEndPosition, AvailableWirelessNetworksData, "Band") > 0 Then '  If the AvailableWirelessNetworksData contains 'Band' data then ...
            IncrementalStartPosition = InStr(InStr(IncrementalEndPosition, _
                    AvailableWirelessNetworksData, "Band"), _
                    AvailableWirelessNetworksData, ":") + 1                             '       Find the start character position of the Band in AvailableWirelessNetworksData
'
            IncrementalEndPosition = InStr(IncrementalStartPosition, _
                    AvailableWirelessNetworksData, "Channel")                           '       Find the end character position of the Band in AvailableWirelessNetworksData
'
            ResultArray(ArrayRow, 4) = Mid$(AvailableWirelessNetworksData, IncrementalStartPosition, _
                    IncrementalEndPosition - IncrementalStartPosition)                  '       Save the Band into the ResultArray
        Else                                                                            '   Else

This is the output I get in the AvailableWirelessNetworksData variable

VBA Code:
SSID 2 : Orange-FB8
    Network type            : Infrastructure
    Authentication          : WPA-Personal
    Encryption              : CCMP
    BSSID 1                 : 7c:7d:3d:71:fb:88
         Signal             : 100%
         Radio type         : 802.11n
         Channel            : 2
         Basic rates (Mbps) : 1 2 5.5 11
         Other rates (Mbps) : 6 9 12 18 24 36 48 54

As you said, no Band Data.

Nothing being placed in the clipboard? That line of code should put the results into the Windows clipboard, not the Excel clipboard.
Yes I know. but it doesn't put the data into the Windows cliboard either.
I believe, it needs admin privileges because when I run the command in cmd.exe, I need to lauch cmd.exe as admin otherwise it doesn't work.
But since you are now not using the clipboard (which is cleaner) , elevated privileges shoudn't be a problem, I think.

Maybe, as you said, you could consider placing the output data in a tmp txt file.

In fact, you may still have a problem using the Run Method even without placing the data in the clipboard.
I just ran netsh wlan show networks mode=bssid from cmd.exe and it doesn't work unless cmd.exe is ran as Admin.
