Explanation: To populate a dataset with data using a data adapter, you need to use the Fill method of the data adapter.

Option A) CustomerDataset.Fill(CustomerDataAdapter) - This option is incorrect because the Fill method is called on the data adapter, not on the dataset itself.

Option B) CustomerDataAdapter.Fill(CustomerDataset) - This option is correct. The Fill method of the data adapter is used to populate the dataset with data.

Option C) CustomerDataset.Load(CustomerDataAdapter) - This option is incorrect because there is no Load method for a dataset. The Load method is used for loading data into a DataTable, not a dataset.

Option D) CustomerDataAdapter.Load(CustomerDataset) - This option is incorrect because there is no Load method for a data adapter.

Therefore, the correct answer is Option B) CustomerDataAdapter.Fill(CustomerDataset). This option is correct because it calls the Fill method of the data adapter to populate the dataset with data.

The correct answer is B.

To solve this question, the user needs to have some understanding of how datasets work and how positions are assigned in programming.

The position property of the first record in a dataset is usually assigned a value of 0. This is because many programming languages use zero-based indexing for arrays and data structures.

Therefore, the correct answer is:

The Answer is: A) zero

To answer this question, the user needs to know what the DataMember property is used for in the context of data access in .NET applications.

The DataMember property is used to specify the name of the database table or view that the data is retrieved from. Therefore, the correct answer is:

The Answer is: E. Database table

The correct answer is (D) Both a and b.

The DataGrid control has two properties that allow you to bind it to a data source:

• DataSource: This property specifies the data source that the DataGrid will be bound to. The data source can be a DataSet, DataTable, or any other object that implements the IBindingSource interface.
• DataMember: This property specifies the data member in the data source that the DataGrid will display.

The DataQuery property is not a property of the DataGrid control. It is a property of the BindingSource object that is used to bind the DataGrid to a data source.

Here is an explanation of each option:

• Option A (DataSource): This is a property of the DataGrid control that specifies the data source that the DataGrid will be bound to. The data source can be a DataSet, DataTable, or any other object that implements the IBindingSource interface.
• Option B (DataQuery): This is not a property of the DataGrid control. It is a property of the BindingSource object that is used to bind the DataGrid to a data source.
• Option D (Both a and b): This is the correct answer because the DataGrid control has two properties that allow you to bind it to a data source: DataSource and DataMember.
• Option E (All of the above): This is not the correct answer because DataQuery is not a property of the DataGrid control.
• Option C (DataMember): This is a property of the DataGrid control that specifies the data member in the data source that the DataGrid will display.

To solve this question, the user needs to have knowledge of HTML and the syntax used for HTML tags.

The correct answer is:

B. < >

HTML tags are enclosed by angle brackets (< >). The opening tag is represented by , and the closing tag is represented by . The content between the opening and closing tags is affected by the tag.

A. ( ): Parentheses are not used to enclose HTML tags. They have other purposes in programming and mathematics.

C. [ ]: Square brackets are also not used to enclose HTML tags. They are used in other programming contexts, such as arrays or character classes in regular expressions.

D. { }: Curly braces are not used to enclose HTML tags. They have various uses in programming languages, such as defining blocks of code or representing sets in mathematics.

E. None of the above: This option is incorrect because, as explained above, HTML tags are enclosed by angle brackets (< >).

The Answer is: B. < >
