I am trying to build an HTML string which I then want to display in my WebView2 control which is called WebView2_1. The code is as follows:
Dim selectQuery As String = "SELECT name FROM chats;"
Using command As New SQLiteCommand(selectQuery, sqlite_conn)
Using reader As SQLiteDataReader = command.ExecuteReader()
' Iterate through the records and display names in WebView2
Dim namesHtml As New System.Text.StringBuilder()
namesHtml.AppendLine("<html lang=""en"">")
namesHtml.AppendLine("<meta charset=""UTF-8"">")
namesHtml.AppendLine("<ul>")
While reader.Read()
namesHtml.AppendLine($"<li>{reader("name")}</li>")
End While
namesHtml.AppendLine("</ul>")
WebView2_1.CoreWebView2.NavigateToString(namesHtml.ToString())
'MsgBox(namesHtml.ToString())
End Using
End Using
The error I am getting is on this line:
WebView2_1.CoreWebView2.NavigateToString(namesHtml.ToString())
System.NullReferenceException: 'Object reference not set to an instance of an object.'
Microsoft.Web.WebView2.WinForms.WebView2.CoreWebView2.get returned Nothing.
Do I need to initialise the control in some way or have I made another mistake?
Thanks very much
