Microsoft Office Access 2003 Inside Out The procedure begins by checking to see if the old Web page file exists using the Dir function. If it finds the file, it deletes it using the Visual Basic Kill statement. Next, the procedure takes advantage of the ability to read and write files that s built into Visual Basic. The code uses the Open statement to create a new .htm file, followed by a series of Print statements to write the heading tags to the file. You can also use a Write statement to write to a file opened this way, but Write includes double quotes around string variables or literals that you write to the file. Print writes only the text you specify. The code opens a recordset on the tblDepartments table, sorted by department name. It creates an HTML table with a caption and a heading for each department. It opens a second recordset for all the employees in the department and loads the HTML table rows using information from the employee recordset. After writing out all the employees for the current department, the code writes tags to close off the table and create a space between tables. The code moves to the next department and loops back to start a new HTML table for the next department. When it has finished with the last department, it closes off the Web page with </Body> and </HTML> tags. You can open the modHTML module, click anywhere in the function, and click the Run button on the toolbar to run the code. After the code completes, you can open the EmployeePhone.htm file that you can find in the \Webs\StaticHTML folder. Figure 26-14 shows you the result.
