Generally, this type of error comes while you working with Microsoft Access database connectivity with ADO. NET or when you work with Desktop applications which read from and write to various files formats including Excel, CSV, Access, Text files etc at that time you may have received following errors. The 'Microsoft. This is a very typical issue when you run your projects that are written in Visual Basic and Visual C in Visual Studio version , , , You Just try the subsequent solutions as I show you in this article and one by one until you fix the issue.

I have Visual Studio installed on my system. I also face the same problem i. After setting output to x86 in place of x64, the problem gets resolved. This worked for me as well.. The Open method of the Recordset object enables you to specify an optional cursor parameter that determines how the underlying provider retrieves and navigates the recordset.
By adding the adOpenKeyset cursor parameter to the statement used to execute the query, you enable the client application to fully navigate the recordset. As a result, the application can use the RecordCount property to accurately count the number of records in the recordset. See the following example:. With the ADO Command object you can execute queries in the same way as queries executed with the Connection and object you can execute queries in the same way as queries executed with the Connection and Recordset object, except that with the Command object you can prepare, or compile, your query on the database source and then repeatedly reissue the query with a different set of values.
The benefit of compiling queries in this manner is that you can vastly reduce the time required to reissue modifications to an existing query. In addition, you can leave your SQL queries partially undefined, with the option of altering portions of your queries just prior to execution. The Command object's Parameters collection saves you the trouble of reconstructing your query each time you want to reissue your query. For example, if you need to regularly update supply and cost information in your Web-based inventory system, you can predefine your query in the following way:.
ADO parameters, such as adCmdText , are simply variables, this means that before using an ADO parameter in a data access script you need to define its value. Since ADO uses a large number of parameters, it is easier to define parameters by means of a component type library, a file containing definitions for every ADO parameter and constant. In the previous example, you will note that the script repeatedly constructs and reissues a SQL query with different values, without having to redefine and resend the query to the database source.
Compiling your queries with the Command object also offers you the advantage of avoiding problems that can arise from concatenating strings and variables to form SQL queries. In particular, by using the Command object's Parameter collection, you can avoid problems related to defining certain types of string, date, and time variables.
For example, SQL query values containing apostrophes ' can cause a query to fail:. By binding the query value as a Command object parameter, you avoid this type of problem. Web pages containing HTML forms can enable users to remotely query a database and retrieve specific information.
With ADO you can create surprisingly simple scripts that collect user form information, create a custom database query, and return information to the user. For example, the following script block inserts information supplied by an HTML form into a table. The script collects the user information with the Request object 's Form collection. One of the main challenges of designing a sophisticated Web database application, such as an online order entry application that services thousands of customers, is properly managing database connections.
Opening and maintaining database connections, even when no information is being transmitted, can severely strain a database server's resources and result in connectivity problems.
