There is no error in the code, but the error is thrown due to the following:
- Please check whether you have given Read-write permission to MS-Access database file.
- The Database file where it is stored (say in Folder1) is read-only..?
suppose you are stored the database (MS-Access file) in read only folder, while running your application the connection is not force-fully opened. Hence change the file permission / its containing folder permission like in C:\Program files
all most all c drive files been set read-only so changing this permission solves this Problem.
