You can please use following code snippet in order to generate an OMR Template using the API:

Private Sub SurroundingSub()
    Dim engine As OmrEngine = New OmrEngine()
    Dim res As GenerationResult = engine.GenerateTemplate(Path.Combine(testFolderPath, "Grid.txt"))

    If res.ErrorCode <> 0 Then
        Console.WriteLine("ERROR CODE: " & res.ErrorCode)
    End If

    res.Save(outputPath, "Grid")
End Sub

For further information and examples please check following documentation section. You can use any code converter to convert C# code into VB:

Dear Sir

Thank you for your quick reply. I have tried but doesn’t work. I am using Visual Studio 2015 and the project is ASP.net webform code behind.

Here is my code:

Imports Aspose.OMR
Imports Aspose.OMR.Generation

I got an error from
“Dim engine As OmrEngine = New OmrEngine()”
Error Message:
Initializes a new instance of the OmrEngine class
Overload resolution failed because no accessible ‘New’ accepts this number of arguments
It needs parameter in ‘New’ engine.

And
Dim res As GenerationResult = engine.GenerateTemplate(Path.Combine(testFolderPath, “Grid.txt”))
Error Message:
GenerateTemplate is not a member of ‘OmrEngine’

Thanks again for your support.

Regards

Churchill

Dear Sir

Thanks for your support. I found the solution. The problem can be fixed by add
Imports Aspose.OMR.Api
Imports Aspose.OMR.Generation

I can generate a template now.

Thank you
