Send params to DosBox

Hi,

This is the code I wrote to automate the loading of a game, etc in Dosbox without having to manually edit the config file or enter the lines in to Dosbox each time.

vb Code:

        ' to finish, hiding while we wait.
        Private Sub ShellAndWait(ByVal program_name As String)
        Dim process_id As Long
        Dim process_handle As Long
         
            ' Start the program.
            On Error GoTo ShellError
            process_id = Shell(program_name, vbNormalFocus)
            On Error GoTo 0
         
            ' Hide.
            Me.Visible = False
            DoEvents
         
            ' Wait for the program to finish.
            ' Get the process handle.
            process_handle = OpenProcess(SYNCHRONIZE, 0, process_id)
            If process_handle <> 0 Then
                WaitForSingleObject process_handle, INFINITE
                CloseHandle process_handle
            End If
         
            ' Reappear.
            Me.Visible = True
            Exit Sub
         
ShellError:
            MsgBox "Error running '" & program_name & _
                "'" & vbCrLf & Err.Description
        End Sub
       
        Private Sub Command1_Click()
         commands
         loadDosbox
        End Sub
     
    Private Sub commands()
    ff = FreeFile
    Open "C:\Users\Aaron\AppData\Local\DOSBox\" & "dosbox-0.74.conf" For Append As #ff
    Print #ff, "mount c e:\dosgames -freesize 1000"
    Print #ff, "mount d e:\dosgames\dfcd -t cdrom -label Daggerfall"
    Print #ff, "d:"
    Print #ff, "install"
    Print #ff, "mount c e:\dosgames -freesize 1000"
    Print #ff, "mount d c:\dosgames\dfcd -t cdrom -label Daggerfall"
    Print #ff, "c:"
    Print #ff, "cd/dagger"
    Print #ff, "dagger"
    Close #ff
    End Sub
     
    Private Sub loadDosbox()
    Dim sYourCommand As String
    sYourCommand = """" & "C:\Program Files (x86)\DOSBox-0.74\DOSBox.exe"
          ShellAndWait sYourCommand
    End Sub

Edit:

To use just make sure you open the config file in the above location via the "DOSBox 0.74 Options" bat file.
