Database Couldn't Be Found In Visual Studio 2010 C# - c#

I've been creating an application using Visual Studio 2010 C# and Microsoft Access 2007. I am new to this and I am experiencing some errors. I've tried using MySQL as a database before but when I changed it to MS Access 2007, there are errors occured stating that the database format is not recognized.
Here's the print screen:
The file type of the database I created is .accdb.
Please help. Thanks

The driver you are using to connect accdb database is outdated, install Access 2010 Driver and then change your connection string in this way :
string MyConString = Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\pathofyourDatabase.accdb

Either the database is encrypted or you don't have the proper Access engine for the architecture (x86/x64). Visual Studio is also 32-bit and probably can't connect to x64 database. See this post.

Data Source Configuration Wizard: Could not retrieve schema information for table or view

As the title says, I could not proceed in creating a data source for datagridview. I can see the database and the tables fine, but when I click finish, an error comes up.
What I've done so far:
-Reinstalled MySQL for Visual Studio
-Reinstalled MySQL Connector/NET
-Updated MySQL Updated
-Visual Studio 2017
Any ideas?
BTW I'm using Windows 7 64 bit, Visual Studio 2017 Community, and MySQL 8.0.13. Programming Language is C#
Here's a screenshot.
Data Source Config Wizard Error
This is a bug in the MySQL Visual Studio integration; it has been reported as bug 92751.
You can subscribe to updates on that case to learn when Oracle has fixed the bug and released an updated version. As far as I know, there is no workaround.

Unrecognized database format accdb in visual studio

I am using visual studio community 2017
Access 2010 - 2016
I can import an access file I created
File sent from client contains(tables, queries, forms, macros, and modules)
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\jeremiah\Documents\Batching.accdb
The client sent me another basic file, was able to open without a problem
So I been through all current StackOverFlow solutions for people reporting the unrecognized database error and none of them have been useful.
My only theory is that the database they are using is to complicated to be used as a data source for visual studio.Do you have any suggestions?
I may not tell you what the problem is but I solved this issue before by resaving the database file as Microsoft Access 2003. Goto Save Database As Access 2002-2003 (*.mdb) and then use the new file.
You need use ACE.OLEDB 32 bits in Visual studio connection. (click in Advanced... button in Add Conection screen)
The visual studio try use of Jet.OleDB not more supported.

How to add local database file to Visual Studio Mac 2017

I'm creating a hotel management service in C# on Visual Studio (Mac) and I can't seem to find a good explanation on how to add a local database file to my project. I created my database table in open office (.odb file) but there doesn't seem to be a way for me to implement this in my project. The documentation has nothing on this either. Any one got a clue how to add databases to a Mac Visual studio project?
there are no localDB in visual studio for mac, you need to install the docker image for sql server.
here is the link
You can run SQL Server on a Mac now:
https://database.guide/how-to-install-sql-server-on-a-mac/
Using Docker it can be made as your localhost SQL Server. I've done this and it works. SQL Management studio for Mac is useful too.
Hope this helps someone.

How to connect to database with Visual Studio 2017 in C#?

I'm currently using Visual Studio Community2017, and I created a Windows Form, but I'm having a problem when I come to connecting my Windows Form to a Database.
I was using Visual Studio 2013 before, and I remember that to connect to a SQL Database, I just had to install an extension to my project, and then I could use the library of MySQL.
But in the 2017, I can't find the same thing.
I tried to follow the instructions of the .NET tutorial on Microsoft's website, but didn't manage to make it work properly, I didn't understand all the steps.
Can anyone help me ? Thanks a lot :)
I already used MySQL with PHPMyAdmin with Eclipse.

Unable to convert runtime connection string to its design-time equivalent

I updated to Visual Studio 2013 last week and I can no longer update my Entity Data model through the visual studio designer (.edmx file).
When I right click > update model from database I now receive this error:
An Exception of type 'System.ArgumentException' occurred while
attempting to update from the database. The exception message is:
'Unable to convert runtime connection string to its design-time
equivalent. Connection string: server=192.168.100.103;user
id=xxx;password=xxx;database=xxx;persist security info=True'.
My connection string is as follows:
<connectionStrings>
<add name="DbEntities" connectionString="metadata=res://*/Db.csdl|res://*/Db.ssdl|res://*/Db.msl;provider=MySql.Data.MySqlClient;provider connection string="server=192.168.100.103;user id=xxx;password=xxx;database=xxx;persist security info=True"" providerName="System.Data.EntityClient" />
The process still works fine in Visual Studio 2012
Apparently MySql and Visual Studio 2013 don't work together yet.
Here is a link on the MySql forums:

You'll probably need to wait for the next release of the MySql connector.
I can't even create a connection to a MySql DB from Server Exploer in Visual Studio 2013. Can you?
You need to download Mysql connector 6.8.3.0 and Mysql for Visual Studio 1.1.1(https://cdn.mysql.com/Downloads/MySQLInstaller/mysql-visualstudio-plugin-1.1.1.msi)
After that, it worked for me.
There is a new product for this now:
http://dev.mysql.com/downloads/windows/visualstudio/
Worked for me!
I had a similar problem with SQL Server Compact Edition. Although implied above, I'll explicitly state it: The answer for me was starting it in VS2012 and following the same steps to generate the database from the .edmx as I had tried in VS2013.
Most likely you are using an older version of MYSQL for VS or do not have any installed.
Simply Install/Update MySQL for visual studio
here : http://dev.mysql.com/downloads/windows/visualstudio/
This Worked for me
I also had this error message with Oracle. I previously had the Oracle ODT installed to make everything work with Visual Studio with our old database. However, I upgraded from the 12.1 to 12.2 ODT version of the tools when we migrated to a 12.2 server. That's when I started getting the above error.
For me, the fix was to update the machine.config. Change all references to the old driver version to the new driver version. In my case, I updated the Oracle.ManagedDataAccess from 4.121.1.0 to 4.122.1.0.
The problem is likely that MySQL for Visual Studio is missing. This can happen when Microsoft updates Visual Studio OR any related components.
You can check by:
Open your VS project.
Open Server Explorer and click on the connection.
Right click and open Properties. If the connection or provider are missing reinstall the connector and provider according to the instructions shown below:
STEPS on how to fix the problem:
NOTE: This uses version 6.8.10, your version may be different. Whatever version you use, all installed components MUST BE COMPATIBLE. That includes the Connector, MySQL for VS, and the MySql.Data components in your project.
This happens to me when MySQL version is updated.
I have found that doing the following steps can solve it:
Update the project nuget packages for MySQL to the latest.
Close Visual Studio.
Lunch MySQL Installer and update the product ".Net Connector" to the latest.
In MySQL Installer - remove the product "MySQL for Visual Studio"
In MySQL Installer - reinstall the product "MySQL for Visual Studio"
When you will open Visual Studio and update your model, you will be asked to update some MySQL files from PKGDEF files. Click on yes and everything should work.
