Corresponding connection string:
Oledb connection string: "provider = Microsoft. Jet. oledb.4.0; Data Source = c: \ test. XSL; extended properties = Excel 8.0"
ODBC connection string: "Driver ={{ Microsoft Excel Driver (*. XLS) }}; DSN = ''; readonly = false; create_db = \" C: \ test. XSL \ "; DBQ = c: \ test. XSL"
When open () is enabled, this error is reported: "cannot be updated. The database or object is read-only"
Note that no. The data file c: \ test in the above two connection strings. XSL, It is easy to confuse, changed to c: \ test. XlsWhen open () is executed, test.xls is created under c: \. Of course, if it is in another folder, make sure that the folder is Excel ProgramShould have the write permission.
