Hello, when i try to login to the created account it says that con.Open(); command isn't working
"Microsoft.Jet.OLEDB.4.0' provider is not registerd on the machine", how to fix this error
Hi, great work. Maybe you can update your code with " How to login to a secure/password protected access database". The login is useles because everyone can read the user and password directly from the db and log in after that.
The credentials cannot be read in the database if you are using a password for the database.
@@CodeCraks Do you have an idea how to do something like this? To get some information (Excel, Access, mysql, etc) that is protected to a c# form ?
too useful.. thanks🖤🖤

Help?
Bro you videos are so nice
Glad you like them!
Can you make a video how to allow duplicates on Microsoft Access 2007?
U can make video login and register with sql sever.
Thanks
Nice video, one question though. When your opening each form, you are creating a new object, and once your done with it you just hide it. If you keep hitting the register account, will that not leave a lot of forms hidden in the background instead of closed?
It will. but this small programs want take much RAM so its not a matter
Hi CodeCraks, Kindly assist. Im using visual studio 2022 it all works except the cmd.ExecuteNonQuery I was wondering if your could tell me how to fix this because i couldn't find a solution

the thing is others wont be able to log on the other accounts cuz it doesnt have it saved on a server or smth its only on database
you lost me when you opened powerpoint
What ? When ?
@@raoufsnowden2988thinnk he means access
Hi CodeCraks, Kindly assist. Im using visual studio 2022 and does not seem to have OleDbConnection. do you perhaps have a solution around this?
It should be there because that's used to connect the database
@@CodeCraks I cant seem to find it is there a way you might know to add that property
legit vid
anyways i got this error: System.InvalidOperationException: 'The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.'

@@CodeCraks Hey do you have a discord?
FINALLY AFTER 5 MONTHS
Yeah😀
could you maybe make a video on how to add a working "Remember me"
Hey I downloaded your source but I have an issue. Whenever you try to create an account that has already been created it gives an error message. Do you know how to fix it?
Ya this is because access databases don't let to create duplicate values so this is impossible. But you came change the databases fields properties to allow duplicate value. This solves you issue
Hi can someone help me with the running bit? How do I run it on my desktop?
Start using visual studio
@@CodeCraks ok yeah I didn’t know what I was talking about then. I already did the entire thing in visual studio. My problem is “Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.” After I enter credentials it just fails and displays that.

Sorry, when you created this project, you used a database from Microsoft Access software. If you use SQL Server Management Studio software, will the results still be the same? Coincidentally, I also tried using SQL Server and the result was an error😅
please help when I log in it says con.Open(): Exception Unhandled System.InvalidOperationException:'THe connection was not closed.The connection's current state is open
Add con.Close() after the database connection code.

invalid sql statement when i try to register ??
@CodeCraks I keep getting a error System.InvalidOperationException: 'Invalid attempt to call Read when reader is closed.'
It is possible to create an account on a website and then use that account to purchase a program on that page. I would later download the program from the site and would have to log in program with the same information as I logged in on the website. I would also like to make it possible for only one device to be logged into an account at the same time.
Is that possible?
So you want to sell a program but u want them to reigster on website and the after they register website they can login on the application and use it.

Thanks for you feedback
@@CodeCraks how do i link it to "SQL" instead of "ACCESS" ?
Hello I have a question, what if the user creates a new account with a username already used? By the way, good video!
For that you can have two solutions
1. Add a Try, Catch to the Code so the program can alert the user that it is a duplicate record.
2. You can change Allow Duplicates in the database
@@CodeCraks ok, thanks
@@CodeCraks and how to do that exactly , can u explain it further or make another video about it
If(username == USERNAME)

Question, I wana make it too where Different people can Log in. But I dont want them to be able too see other peoples login info how do I do that.
Are you trying to make poeple login from different computers or just in your own computer?
@@CodeCraks from different computers , like im making a multi tool , that has a login. I have the database and everything but i wana be able to share the database around with the tool working but people not being able too see other peoples login.
Then you must change the database from access to remote mysql, by then you can login from any computers remotely. But it needs an internet connection.
@@CodeCraks how do I do that?
First of all you must own a mysql server with remote mysql support and enough database storage.
is there a way to do this without office access cause i dont have 20$ to spend on it as of right now
Did you find another way?

hi how i can delete accounts ?

Ya you should make a separate field for a user type then when you create a account keep a field to select whether user type
check when the application start where its a admin or not then if it is a admin login give access to admin and if it is a user login don’t display those features
