QUESTION
I'm working on a school project and I ran into a problem. When I insert/update/delete data from the database, the data isn't shown before I restart the application. I have to close the app and open it again for it to show changes.
When I change the OleDbConnection
string (when I change the source), data is updated but it's only shown until I close the app, when I close the app I lose all the new data. Data from the database is shown in dataGridView
. When I choose the data source for dataGridView
the code line is written automatically in form load event with that code I can update data when the source is changed to the file that doesn't save data.
I'm wondering if there are any other ways to automatically refresh(or with a button) dataGridView
after new data has been added. I'm using VS C# 2008 express edition because that is the one we use in school.
Here's the code for the insert button:

Answered 2021-May-03 at 20:37OK the reason you're hitting problems and different behaviors when you change the connection string is one of:
- There are two databases on disk, and you're looking in the wrong one
- You're doing your data access in the wrong way
You're hitting both of these. First, i'll explain the first one.
When you added the access database to your project (however you did it, there are a few ways) this dialog box (or similar - this is vs 2019) probably appeared
It is long and boring, and tells people a lot of stuff they probably don't understand so they just hit Yes and forget about it. Later they will be very confused when trying to save data
This box is basically saying "i'll copy the db into your project folder, but remember that every time you press play, it will be copied again to the BIN folder and your running program will modify the database in the bin folder, not the db in the project folder, and not the db from your desktop (or wherever)"
Later the dev runs the program, saves some data, looks in Access, doesn't find it. Or they run the program again and wonder "where is my data gone that I just saved".
"Every time you run the program the db from the project folder is copied to the bin folder"
It means the database your program saves its data in will be wiped and replaced every time you build your project in visual studio. It doesn't affect a live app (live apps don't build themselves every time you run them), just one you run in VS
And if you look in any db other than the one in BIN folder, you wont find the data, because you're looking in the wrong one
I suggest you find your DB in solution explorer, right click it, choose Properties and change "Copy to output" to "Copy If Newer". This way VS will only replace the db in the bin folder when you've made a change to the db in the project folder (i.e. added a new table) - this is more like what you want to do, usually
Now I commented that you're doing your data access incorrectly:

QUESTION
I have python script which is using google STT engine and then it loops through dictionary to check where is the biggest match (ratio) using difflib SequenceMatcher
UPDATE (better explanation of what script needs to do):
- variable izgovoreno contains string (from google STT engine,actually microphone) - let's say it's value is "lights"
- there is nested dictionary where each hotword (like "lights on", "blinds shut" etc.) contains correspoding command. There is "hotword" and there is "komanda". In this example hotword value is lets say "lights on" and corresponding komanda is "execute some code to turn on the lights"
- komanda will only be executed if there is some percentage(at least 50% or 0.5 in decimal) match between variable izgovoreno and hotword. So, there is a for loop which goes thru dictionary and using difflib.SequenceMatcher compares variable izgovoreno with all hotwords from dictionary, and then it writes result (percentage) to key "razlika_izgovoreno_hotword" for each corresponding hotword.
- Now we have dictionary with this data (example):

QUESTION
I built a software that has a login form at the beginning where the user enters the username and the password and if the username and the password are correct a message is printed and the user has access to the program.
My problem is that this all works as it should but if the password or username is incorrect instead of my custom message i get a NullReferenceException
.
If anyone has a guess what this could be please help me.
So far here is what i have tried :
...ANSWER
Answered 2020-Jan-11 at 23:30This is happening because ExecuteScalar()
returns null
if the query finds no results (zero matching rows). And trying to cast null
to an int
will cause a NullReferenceException
.
There are several fixes:
- You can use
object obj = ...ExecuteScalar();
and then check ifobj
is null or not before casting it toint
. - You can cast the
ExecuteScalar()
outcome toint?
which can handlenull
, meaning that the conversion will not crash anymore. And then check that result fornull
.
