How Use a Object value in Data set Query insert

As a rule of thumb, you should not compose your query out of the data such as TextBox.Text. Instead, you should create one or more parametrized queries, create one or more database Command and re-use it by passing parameters from your data. You did not tell us what database provider you want to use; and I don't want to give you examples of all possible cases, as different mechanisms are used for different database providers: it can use named or positional correspondence between formal query parameters and objects.
