Server side code to handle SystemClipboard

[Adrianus PJM Van Geel at TwoAgree]

Hi, I am using the JS Document Editor and want to activate/allow Copy & Paste of text from a client running program into the Syncfusion Document Editor.  I found that I need an ASHX to realize this. I have such ASHX already. I added below code (CoPilot) for this but Visual Studio reports errors on the lines with remark #1423. All errors are that method or property doesn't exist.
(Sorry, its Visual Basic, I am already somewhat older.)

Can anyone supply the correct lines?

````

Imports Newtonsoft.Json

Imports Syncfusion.EJ2.DocumentEditor

````

````

            Case "SystemClipboard"

                ' new paste-action

                Dim htmlContent As String = context.Request.Form("content")

                ' HTML to DOCX fragment

                Dim document As New WordDocument()

               document.XHTMLValidateOption = XHTMLValidationType.None    '#1423

              document.InsertXHTML(htmlContent)   '#1423

                ' Important: DocumentEditor expects JSON, not DOCX-file

                Dim json As String = Newtonsoft.Json.JsonConvert.SerializeObject(document)

               document.Close()    '#1423

                context.Response.ContentType = "application/json"

                context.Response.Write(json)

Good info

It was solved with this code in our DocumentHandler.ashx.vb (selective lines only):

  Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest

    Dim Response = context.Response

    ' Handle action

    Select context.Request.HttpMethod

      Case WebRequestMethods.Http.Post :

        Dim action As String = context.Request.Form("action")

          Select Case action

            Case "SystemClipboard"

              ' 1. Read the body and pick up its bytes (JSON or raw)

              Dim BYTS As Byte() = funExtractBytesFromRequest()

              ' 2. Determine format automatically (DOCX/RTF/HTML/TXT)

              Dim FORMAT As FormatType = funDetectedFormat(BYTS)

              ' 3. Load document in a safe manner

              Dim myDOC As Syncfusion.EJ2.DocumentEditor.WordDocument = funLoadDocumentSafe(BYTS, FORMAT)

              ' 4. Convert into SFDT‑JSON

              Dim SFDT As String = JsonConvert.SerializeObject(myDOC)

              context.Response.ContentType = "application/json"

              context.Response.Write(SFDT)

              myDOC.Dispose

              Exit Sub

         End Select

    End Select

End sub
