I need to call an external application and before calling some environment variable have to be set. I use the windows api SetEnvironmentVariable but it doesn't work. Is there another method to do this operation?
' This is the declaration.
Declare Function SetEnvironmentVariable Lib "kernel32" Alias "SetEnvironmentVariableA" (ByVal lpName As String, ByVal lpValue As String) As Integer
'  This is the instruction.
SetEnvResult = SetEnvironmentVariable("Mfextmap", lc_mfextmap)
