VB converting string for use as varbinary in MSSQL

I have a long string of data, that is to be stored in a db, with column type of varbinary(max).  Problem is, I can't get an insert statement from within VB that will let me do such.  I tried using the convert command in my InsertQuery string, but it doesn't like the syntax.

THe field that needs to be a varbinary(max) is "ContentData".

The exact error message is "Implicit conversion from data type varchar to varbinary(max) is not allowed. Use the CONVERT function to run this query"

Any ideas?
Dim dbConnection = "User Id=xx;Password=xxxxxx;Server=x.x.x.x;Initial Catalog=Content"
        Dim myConn As New SqlConnection(dbConnection)
        Dim myInsertQuery As String = "INSERT INTO FileContent ( ContentData, ContentName, ContentDate) Values('myContent', 'myContentName', 'myContentDate')"
        Dim myCommand As New SqlCommand(myInsertQuery)
        myCommand.Connection = myConn
        myConn.Open()
        Try
            myCommand.ExecuteNonQuery()
        Finally
            myConn.Close()
        End Try

can't you use something like this?


INSERT INTO FileContent ( ContentData, ContentName, ContentDate) Values(convert(varbinary(max), 'myContent') , 'myContentName', 'myContentDate')

Try using the following syntax

        System.Text.Encoding.ASCII.GetBytes("DataContent")

So your query would be
"NSERT INTO FileContent ( ContentData, ContentName, ContentDate) Values('" & System.Text.Encoding.ASCII.GetBytes("DataContent") & "', 'myContentName', 'myContentDate')

Okay.  THe above solutions are working.  Now another problem is arising.  Instead of the actual values being inserted into the database, the names of variables are being inserted.

Apologies if this is a stupid question.

Here's the error I get upon execution:

The name "mySystemID" is not permitted in this context. Valid expressions are constants, constant expressions, and (in some contexts) variables. Column names are not permitted.

Funny thing in, I don't have columns with that name, and they are variables that I am passing!
