Specifies the user name. If this keyword is not specified, the string, " admin ", is used by default. Specifies the user password.

This value is only valid after a database connection has been established. Indicates the locking mode for this database.
The first user to open the database determines the mode used while the database is open. Indicates whether a compacted database should be encrypted. If this property is not set, the compacted database will be encrypted if the original database was also encrypted. Indicates the maximum length of time, in milliseconds, that Jet can delay asynchronous writes to disk when the database is opened exclusively.
Indicates the amount of time to wait before data stored in a cache for asynchronous writing is written to disk. Indicates whether changes that were made in internal implicit transactions are written in synchronous or asynchronous mode. Whether you are working on Windows or on Web or on Console application, at one stage we need to process data and excel file is widely used for it, so in previous article, we have explained about creating excel in C without interop but in this article, I am going to provide you code to open and read excel file.
Now, if you are working on 64 bit operating system , you may get this error " The 'Microsoft. Now in the Build Menu you will be able to go to the Config Manager and set output to x If your application is web based, then Enable 'Bit Applications' in application pool.
Once you have installed the package, in your Console application "Program. Here is the image, which shows console application output with sample excel file. Additionally, if you try to define an OLEDB connection from an external application one that's running outside of Office by using the Microsoft.
Click-to-Run installations of Office run in an isolated virtual environment on the local operating system. Some applications outside Office may not be aware of where to look for the installation in the isolated environment. To create a new DSN in Access, follow these steps:. You must install an MSI installation of the Microsoft Access Database Engine from one of the following sources so that the calling application can locate the driver and provider.
Note If Office is already installed, side-by-side detection will prevent the installation from proceeding. To install the package, perform a quiet installation by running a command such as the following:. This will create a new workbook with one worksheet if the datasource file testexcel. Use the following snippet:. Here dtSchema will hold the list of all workbooks.
Say we have two workbooks: wb1 , wb2. You can run a simple query to select Data from an Excel workbook. Say your workbook contains tables like w1 , w2. A caution about specifying worksheets : The provider assumes that your table of data begins with the upper-most, left-most, non-blank cell on the specified worksheet. In other words, your table of data can begin in Row 3, Column C without a problem. However, you cannot, for example, type a worksheeet title above and to the left of the data in cell A1.
A caution about specifying ranges : When you specify a worksheet as your source, the provider adds new records below existing records in the worksheet as space allows. When you specify a range named or unnamed , Jet also adds new records below the existing records in the range as space allows.
