How do i get SerialNumber of BaseBoard with WMI? - wmi

Question

A nice example is there to use WMI in Powerbuilder that terminates a running process.
The same technique can be used to get SerialNumber of BaseBoard. I need to extend the same code to handle return values of the WQL query.
The WQL query i want to execute is:
SELECT Product, SerialNumber FROM Win32_BaseBoard
I can execute the query above but dont know how to save the SerialNumber in a variable after the ExecuteStatement() function is called.
Please take a look at the link for complete PowerBuilder code.
How to terminate a process if it has specific folder name in its path?
Following is a portion of a sample code taken from the link above to show the function.
wsh = CREATE OleObject
wsh.ConnectToNewObject("MSScriptControl.ScriptControl")
wsh.Language = "VBScript"
wsh.AddCode(TheCode)
TRY
wsh.ExecuteStatement(FunctionName)
CATCH (RunTimeError Re01)
MessageBox("Query Error", "Following code has some problems.~r~n~r~n" + TheCode, StopSign!)
END TRY
wsh.DisconnectObject()
DESTROY wsh
The important function call
wsh.ExecuteStatement(FunctionName)
What to do after that function call to set my PowerBuilder local variables with the returned SerialNumber of BaseBoard?

Answer 1

OLEObject ole_wsh
Any la_baseboard[]
string ls_message
ole_wsh = CREATE OLEObject
ole_wsh.ConnectToNewObject("MSScriptControl.ScriptControl")
ole_wsh.Language = "vbscript"
ole_wsh.AddCode('Function rtnBaseBoard()~r~n' &
+ 'DIM objBaseBoard(2)~r~n' &
+ 'strComputer = "."~r~n' &
+ 'Set objWMIService =' &
+ ' GetObject("winmgmts:\\" & strComputer & "\root\cimv2")~r~n' &
+ 'Set colItems =' &
+ ' objWMIService.ExecQuery("SELECT Product, SerialNumber FROM Win32_BaseBoard")~r~n' &
+ 'For Each objItem in colItems~r~n' &
+ 'objBaseBoard(0) = objItem.Product~r~n' &
+ 'objBaseBoard(1) = objItem.SerialNumber~r~n' &
+ 'Next~r~n' &
+ 'rtnBaseBoard = objBaseBoard~r~n' &
+ 'End Function')
la_baseboard[] = ole_wsh.Eval("rtnBaseBoard")
ole_wsh.DisconnectObject()
DESTROY ole_wsh
ls_message = "Product: " + string(la_baseboard[1]) + "~r~n" + &
+ "SerialNumber: " + string(la_baseboard[2]) + "~r~n"
MessageBox("Win32 BaseBoard",ls_message)
