Change Data With Feedback In Omicron Control Center Custom Dialog

Welcome to the fifth and final part of the tutorial series about Omicron Control Center (OCC) Custom Dialog. In this tutorial, I will show you how to get a real-time feedback when data was change. This will be helpful that you will be notified what will be the outcome of the changed data. Check the video below.



Now, open the OCC document that we used in the previous tutorial. If you don't have it check this link (Omicron Control Center Custom Dialog - Creating Custom Dialog With Dropdown Control) then come back here once you have OCC document.

When the document is loaded, open the script view by clicking the Script View button under the View tab then stop the script if its running.

Now, find the SetTheSourceController sub procedure. We're going to modify this codes and use different methods of loading data from the test object and saving back to test object. Point the mouse pointer and click between Begin Dialog and End Dialog then click the Edit Dialog button under the Tools group at Script tab to position the cursor inside the dialog. Make sure the cursor is inside the Begin and End Dialog because if not, it will create a new dialog instead of editing the existing dialog.

Once the UserDialog Editor open, right click on the form to edit the UserDialog properties. Type SourceControllerFunction in the Dialog Function without space, to automatically create a SourceControllerFunction procedure in the Script window. Now, add cancel button in the form then click the save and exit button from the toolbar. See the image below.


Click the Yes button to create a new SourceControllerFunction function. At the very end of the script, new function has been added.

Rem See DialogFunc help topic for more information.
Private Function SourceControllerFunction(DlgItem$, Action%, SuppValue?) As Boolean
	Select Case Action%
	Case 1 ' Dialog box initialization
	Case 2 ' Value changing or button pressed
		Rem SourceControllerFunction = True ' Prevent button press from closing the dialog box
	Case 3 ' TextBox or ComboBox text changed
	Case 4 ' Focus changed
	Case 5 ' Idle
		Rem Wait .1 : SourceControllerFunction = True ' Continue getting idle actions
	Case 6 ' Function key
	End Select
End Function

Now, we have to move the Source_Array and Soure_Enum from the SetSourceController procedure to the main or general class.

' ************************************************************
' This is module *Module1 .
' Automatically generated uses comments are placed here.
' Don't edit these lines.
' {BEGINUSES}
'#Uses "*Module1"
' {ENDUSES}
' ************************************************************

Public Const BASIC_INFO_PATH As String = "CUSTOM.RELAY_INFORMATION.BASIC"
Public Const SOURCE_PATH As String = "CUSTOM.RELAY_PARAMETERS.SOURCE"
Public Const TEST_CONTROLLER_PATH As String = "CUSTOM.TEST_CONTROLLER"
Public GlobalTO As XRio

Dim Source_Array() As String
Dim Source_Enum As AutoParameter

Now, we have to create a new function that getting data from the test object like Source Name data to display when the source data has changed.

Private Function GetSourceControllerFeedback(Reference As String) As String
	Select Case Reference
		Case "Source 1"
			GetSourceControllerFeedback = GetDisplayString (GlobalTO.XRioDocument.GetParamFromIDs(SOURCE_PATH & ".SOURCE1.NAME"))
		Case "Source 2"
			GetSourceControllerFeedback = GetDisplayString (GlobalTO.XRioDocument.GetParamFromIDs(SOURCE_PATH & ".SOURCE2.NAME"))
	End Select
End Function

Now, navigate to SourceControllerFunction function then start new coding. First, we have to initialize the dialog box. Under Case 1, we're going to load the enumeration data to the dropdown list and display the current source name in the selected source name textbox. Next, move the Source_Array and Source_Enum from the SetSourceController procedure to inside the Select Case 1 at SourceControllerFunction. Next, we have to set the selected source name textbox to read only by using DlgEnable and set it to False so that we can't edit the data.

Rem See DialogFunc help topic for more information.
Private Function SourceControllerFunction(DlgItem$, Action%, SuppValue?) As Boolean
	Select Case Action%
	Case 1 ' Dialog box initialization
		Set	Source_Enum = GlobalTO.XRioDocument.GetParamFromIDs(TEST_CONTROLLER_PATH & ".SOURCE")
		Source_Array = GetParameterEnumList(Source_Enum)

		DlgEnable "txtSelectedSource",False

		DlgListBoxArray "dlbSource",Source_Array()
		DlgValue "dlbSource",GetEnumIndex(Source_Enum)

		DlgText "txtSelectedSource", GetSourceControllerFeedback(DlgText("dlbSource"))
	Case 2 ' Value changing or button pressed
		Rem SourceControllerFunction = True ' Prevent button press from closing the dialog box
	Case 3 ' TextBox or ComboBox text changed
	Case 4 ' Focus changed
	Case 5 ' Idle
		Rem Wait .1 : SourceControllerFunction = True ' Continue getting idle actions
	Case 6 ' Function key
	End Select
End Function

Now, in the Select Case 2, this will be triggered when the objects (DlgItem) in the dialog box is pressed. We have need to add Select Case DlgItem for dlbSource, btnOK, CancelButton in this case.

Rem See DialogFunc help topic for more information.
Private Function SourceControllerFunction(DlgItem$, Action%, SuppValue?) As Boolean
	Select Case Action%
	Case 1 ' Dialog box initialization
		Set	Source_Enum = GlobalTO.XRioDocument.GetParamFromIDs(TEST_CONTROLLER_PATH & ".SOURCE")
		Source_Array = GetParameterEnumList(Source_Enum)

		DlgEnable "txtSelectedSource",False

		DlgListBoxArray "dlbSource",Source_Array()
		DlgValue "dlbSource",GetEnumIndex(Source_Enum)

		DlgText "txtSelectedSource", GetSourceControllerFeedback(DlgText("dlbSource"))
	Case 2 ' Value changing or button pressed
		Rem SourceControllerFunction = True ' Prevent button press from closing the dialog box
		Select Case DlgItem
			Case "dlbSource"
				DlgText "txtSelectedSource", GetSourceControllerFeedback(DlgText(DlgItem))
				SourceControllerFunction = True
			Case "btnOK"
				SetEnumValue Source_Enum, DlgValue("dlbSource")
				Set Source_Enum = Nothing
			Case "CancelButton"
				Set Source_Enum = Nothing
			Case Else
		End Select

	Case 3 ' TextBox or ComboBox text changed
	Case 4 ' Focus changed
	Case 5 ' Idle
		Rem Wait .1 : SourceControllerFunction = True ' Continue getting idle actions
	Case 6 ' Function key
	End Select
End Function

Now, back to the SetTheSourceController procedure, we need to declare Integer of DialogResult to get the Dialog result when we click the OK or Cancel button the custom dialog we've created. To see what I mean, execute the SetTheSourceController command to load the dialog box then click cancel button and that will give error called User pressed cancel.


Now,  copy the code below and replace the SetTheSourceController procedure then execute this command.

Sub SetTheSourceController()
	On Error GoTo ErrorHandler
	Set GlobalTO = Document.TestObjects(1).Specific

	Begin Dialog UserDialog 480,105,"Source Controller",.SourceControllerFunction ' %GRID:10,7,1,1
		Text 10,14,140,14,"Source:",.lblSource
		Text 10,42,140,14,"Selected Source:",.lblSelectedSource
		DropListBox 160,14,300,21,Source_Array(),.dlbSource,2
		TextBox 160,42,300,21,.txtSelectedSource
		OKButton 370,70,90,21,.btnOK
		CancelButton 270,70,90,21
	End Dialog

	Dim dlg As UserDialog

	Dim DialogResult As Integer

	DialogResult = Dialog (dlg)

	Set GlobalTO = Nothing

	Exit Sub
ErrorHandler:
	MsgBox(Err.Description, vbOkOnly+ vbCritical,"Error")
End Sub

Now, we have successfully created a custom dialog box with feedback. The overall codes should be looks like the codes below.

So, this is the final tutorial for the Omicron Control Center Custom Dialog series. In the next tutorial, I will show you how to implement UserField in the OCC document with the integration of the custom dialog that we created in this series. Check the video below to see what I mean.


See you next time.

Micom SE Studio1 Import Filter - Creating User Interface (UI)

Welcome to my page and welcome to the continuation of Omicron Import Filter tutorial series. In this tutorial, I will show you how to create the actual import filter fom Micom relays. In this tutorial, we will focus on the Visual Studio program. We're going to modify the codes in our project called MyImportFilter that we've created in the previous tutorial.  Download the project in this link  MyImportFilter - Process Relay Setting Parameters . Extract and open the project. Once the project is loaded, add New Folder inside the project and set the name to SEStudio1. We need this to make organize our project class filter.  SE Studio 1 stands for Schneider Electric Studio 1 which is the software that used in communicating MiCOM relays particularly P12x series. And yes we're going to create a new import filter and user interface form MiCOM P12x series relay. I think this will applied to other MiCOM P series relay. Add a new Form inside the  SEStudio1 folder...
