Getting command line parameters or seeing if they are present is not as easy as you would think. I whipped up some code to make this flexible and easy.
Private Const ParameterPrefix As Char = "/"c
Private Function GetCommandLineArgument(ByVal parameter As String) As String
Dim paramValue = String.Empty
For Each tempValue As String In System.Environment.GetCommandLineArgs
If tempValue.Contains(ParameterPrefix + parameter + "=") Then
paramValue = tempValue.Split(Char.Parse("="))(1).ToString().Trim()
Exit For
End If
Next
Return paramValue
End Function
Private Function CommandLineArgumentExists(ByVal parameter As String) As Boolean
Dim exists = False
For Each tempValue As String In System.Environment.GetCommandLineArgs
If tempValue.Contains(ParameterPrefix + parameter) Then
exists = True
Exit For
End If
Next
Return exists
End Function
Private Function GetCommandLineArgument(ByVal parameter As String, ByVal prefix As String) As String
Dim paramValue = String.Empty
For Each tempValue As String In System.Environment.GetCommandLineArgs
If tempValue.Contains(prefix + parameter + "=") Then
paramValue = tempValue.Split(Char.Parse("="))(1).ToString().Trim()
Exit For
End If
Next
Return paramValue
End Function
Private Function CommandLineArgumentExists(ByVal parameter As String, ByVal prefix As String) As Boolean
Dim exists = False
For Each tempValue As String In System.Environment.GetCommandLineArgs
If tempValue.Contains(prefix + parameter) Then
exists = True
Exit For
End If
Next
Return exists
End Function
Usage:
Debug.WriteLine(CommandLineArgumentExists("source"))
Debug.WriteLine(GetCommandLineArgument("source", "-"))
