'If it is blank, the "add student status information" form is opened.

Private sub modifysinfomenu_click ()

'Define the database connection string
Dim strtxtsql as string
Dim strmsgtxt as string
'Create an object to check whether the student_info table record is empty
Dim rstobjcount as ADODB. recordset
'Create an object that records the return value of msgbox
Dim intmsg as integer

'Database connection statement
Strtxtsql = "select * From student_info"
'Get the record set of student_info and assign it to rstobjcount
Set rstobjcount = executesql (strtxtsql, strmsgtxt)

'Check whether the record in the student_info table is empty
If rstobjcount. recordcount = 0 then
Intmsg = msgbox ("the record set is empty, fill in now or not", vbokcancel, "warning ")

'If yes, the "add information" form is opened.
If intmsg = vbok then
Frmaddsinfo. Show
