Dataset syntax error

From my windows form, I configured a Data Adapter and generated a dataset to
load data from a SQL database table. Then I used a code to fill the dataset.
The code returns the error message: "An unhandled exception of type
'System.Data.SqlClient.SqlException' occurred in system.data.dll
Additional information: System error" in the line that's read
SqlDataAdapter1.Fill(DS_SSCIntake1)

The code I used is the following. What am i doing wrong?

Dim IntakeBindingManager As CurrencyManager
SqlDataAdapter1.Fill(DS_SSCIntake1)
IntakeBindingManager = DirectCast(BindingContext(DS_SSCIntake1, "qmf_cint"),
CurrencyManager).
