I'm getting a "Syntax error converting datetime from character to string".
The returned error says it is located on this line of code: cmd.executenonquery()

Please see code below. All and any help is greatly appreciated. Thanks!

error is from this:
cmd.parameters.add ("@InstallDate", txtinstallDate.text)
try to change to this:
cmd.parameters.add ("@InstallDate",Cdate(txtinstallDate.text))

Of course you need to user's input first.

Changed the code. User now recieves this error: Conversion from string "tbd" to type 'Date' is not valid.
Error is on cmd.parameters.add ("@InstallDate", Cdate(txtinstallDate.text))

you need to check this txtinstallDate.text first.
before you pass this string in, you should put an validation on this field.

try to change like this:
if (txtinstallDate.text != "")
 cmd.parameters.add ("@InstallDate",Cdate(txtinstallDate.text))
 cmd.parameters.add ("@InstallDate",datetime.minvalue)

In the simplest terms how many date columns does the table contain and what are the values you're passing through the command?
