RMCLink COM Component

RMCLink.WriteImage Method

Writes the specified controller image to the controller and applies it to the controller. By default, the image will be saved to flash and the controller will be restarted. The controller image must be obtained using the ReadImage method. For saving and restoring the controller image using a file, use the ReadImageToFile and WriteImageFromFile methods. This method is only supported on the RMC75E, RMC150E, and RMC200 controllers.

Syntax

Visual Basic (Declaration)

Sub WriteImage ( _

   flags As Long, _

   data As Variant _

)

 

Visual Basic (Usage)

Dim instance As RMCLink

Dim flags As Long

Dim data As Variant

 

instance.WriteImageflags, data

Parameters

flags

Options to use when applying the image. Refer to the RMCTools documentation on the Image Area for a current list of options. As of this writing, a single option has been defined. Specify zero (0) to use default options.

+0

Save Image to Flash, and Restart Controller to Apply

+16

Apply Image Immediately and Save To Flash (not supported by RMC200)

data

This variant must be a single-dimension array of Long data type elements that was created using the ReadImage method.

Remarks

This method is synchronous, which means that it will not return until the write is completed, which may take several seconds. If this method is called on the main thread, then the application will likely be unresponsive until this method completes. For applications where this is not acceptable, this and other synchronous methods should be called from a worker thread, and may use the CancelRequest method to cancel an in progress request.

Example

The following code example illustrates the use of the WriteImage method in copying a controller image from one controller to another.

Visual Basic 6 / VBA

Option Explicit
 
Public Sub Sample()
    Dim image As Variant
 
    ' Declare and create the RMCLinkServer COM object.
    Dim srv As New RMCLinkServer
 
    ' Create a new RMCLink object for the first controller.
    Dim rmc As RMCLink
    Set rmc = srv.CreateUSBLink(dtRMC70, "7573091001")
 
    ' Connect to the controller.
    rmc.Connect
 
    ' Read the image into our variable.
    image = rmc.ReadImage(0)
    ' Close the connection.
    rmc.Disconnect
    ' Create a new RMCLink object for the second controller.
    Dim rmc2 As RMCLink
    Set rmc2 = srv.CreateUSBLink(dtRMC70, "7573091002")
 
    ' Connect to the controller.
    rmc2.Connect
 
    ' Read the image into our variable.
    rmc2.WriteImage 0, image
    ' Close the connection.
    rmc2.Disconnect
End Sub

 

VBScript

Option Explicit
Dim srv, rmc, rmc2, image
 
' First we need to create the RMCLinkServer COM object.
Set srv = CreateObject("RMCLink.RMCLinkServer")
 
' Create a new RMCLink object for the first controller.
' NOTE: VBScript does not support enumerations, so we use the literal value (dtRMC70=2).
Set rmc = srv.CreateUSBLink(2, "7573091001")
' Connect to the controller.
rmc.Connect
 
' Read the image into our variable.
image = rmc.ReadImage(0)
' Close the connection.
rmc.Disconnect
' Create a new RMCLink object for the second controller.
Set rmc2 = srv.CreateUSBLink(2, "7573091002")
 
' Connect to the controller.
rmc2.Connect
 
' Read the image into our variable.
rmc2.WriteImage 0, image
' Close the connection.
rmc2.Disconnect

 

JScript

// First we need to create the RMCLinkServer COM object.
var srv = new ActiveXObject("RMCLink.RMCLinkServer");
 
// Create a new RMCLink object for the first controller.
// NOTE: JScript does not support enumerations, so we use the literal value (dtRMC70=2).
var rmc = srv.CreateUSBLink(2, "7573091001");// Connect to the controller.
rmc.Connect();
 
// Read the image into our variable.
var image = rmc.ReadImage(0);
// Close the connection.
rmc.Disconnect();
// Create a new RMCLink object for the second controller.
var rmc2 = srv.CreateUSBLink(2, "7573091002");
// Connect to the controller.
rmc2.Connect();
// Read the image into our variable.
rmc2.WriteImage(0, image);
// Close the connection.
rmc2.Disconnect();
