Hello. I am searching for a sample VB.NET code on how to save a RichTextEdit control to an MSSQL database nvarbinary(MAX) field. I'm trying to use the control's .RtfText but I get a "…string cannot be converted to 1 dimentional array of byte" error.
I would appreciate getting a sample line of code for the saving part.
Hello Yoshihisa,
The RtfText property returns a string in the Rtf format. Since the nvarbinary(MAX) field accepts only binary data, the exception occurs. Use the RichEditControl.OpenXmlBytes property (instead of RtfText) to obtainthe control's content as an array of bytes in Office Open XML (Docx) format and pass this array to your database.
Should you need further assistance, feel free to contact me.
Hi Mariya,
I am now able to save and load to and from MSSQL with the following code:
Save to MSSQL:
.RefDocument = rtfRefDoc.OpenXmlBytes
Load from MSSQL:
rtfRefDoc.OpenXmlBytes = .RefDocument.ToArray
I have a separate data access class to handle my database operation.
Thank you.
