CreateParameter with varbinary

I am trying to create queries to store a MD5 encoded password in SQL server field with datatype varbinary(50)

I get the error "Application uses a value of the wrong type for the current operation. "

Below is the code. What's going wrong??

<%

Set cmdSetPassword = Server.CreateObject ("ADODB.Command")
cmdSetPassword.ActiveConnection = MM_sqldb_STRING
cmdSetPassword.CommandText = "UPDATE Users SET Password = ? WHERE Username = ?"
cmdSetPassword.Parameters.Append cmdSetPassword.CreateParameter("varPassword", 204, 1, 50, MM_IIF(varPassword, varPassword, cmdSetPassword__varPassword & ""))
cmdSetPassword.Parameters.Append cmdSetPassword.CreateParameter("varUsername", 200, 1, 50, MM_IIF(varUsername, varUsername, cmdSetPassword__varUsername & ""))
cmdSetPassword.CommandType = 1
cmdSetPassword.CommandTimeout = 0
cmdSetPassword.Prepared = true
cmdSetPassword.Execute()

Any reason to use varbinary? Why not use varchar?

What is the data type for the value you are assigning to the password?

At the moment I believe it is just a binary value resulting from the MD5 function

i.e....

varPassword = MD5(Password)

Should it be declared a specific way?

Changing the datatype in the database to varchar and the parameter to the same works well. Is there any big difference or risk to doing it this way?

Thanks for the help.
