This is a very Old Snippit of code i had for a small project but

The way it works is a Class exists to hash the password (encrypting it and Decrypting it) when a user add his/her password the application encrypts whatever is on the password field and matches it with what is on the database IF the username and password match a record ont he user table it will proceed to login in.

QUESTION

I want to compare two textbox values to two corresponding columns in a database and then execute save action if the entry is unique

Asked 2021-Jun-01 at 21:13

I have a program which adds values to a database from textboxes.

I need to provide a way through which if the value added is not unique, it should return an error message. But my current code is unable to do that. Even if the value is not unique, it is saving the data in the database.

Below is my code.

ANSWER

Answered 2021-Jun-01 at 21:13

There are couple of approaches to fine tune it

Without touching database

Update the query to select just 1 column instead of *. * selects all the columns which is not necessary to check if the record exists or not.

string query = "Select [Animal ID] from ExpData where 'Animal ID' = '" + textBox5.Text.Trim() + "' and Step = '" + comboBox2.Text.Trim() + "'";

You can also use Exists method which returns a boolean

string query = "Select Exists(Select [Animal ID] from ExpData where 'Animal ID' = '" + textBox5.Text.Trim() + "' and Step = '" + comboBox2.Text.Trim() + "')";

If we change the script then you can use sqlcommand.ExecuteScalar function to just get the value of the column you have included/boolean in the select statement.

With changes to database

Add a unique key constraint on the table ExpData. The unique key should have both columns Animal ID and Step.
Now in the code you can just have a try catch block. IF there is no duplicate record then the insertion will be success. But if the record is duplicate then there will be an exception.
save to database code in try block
In catch block check the exception type along with ErroCode to see if the insertion failed because of the unique key. Check this thread, How can I catch UniqueKey Violation exceptions with EF6 and SQL Server?

My recommended approach

Add unique key constraint on both the columns
Create a stored procedure that
- takes the whole insert data as input
- checks if the record exists then return -1 = if no record exists then insert the new data and return the id of the new record.
In the code you can just check the return value. If the value is a non negative value then the insertion is successful other wise show the message to the user.

If you can change the database then you can reduce one database call if there is not duplicate data.

P.S. You can also use object–relational mapping frameworks like entity framework etc to make it much more easier but it is a big change.

Micropython: [Errno 19] ENODEV but i2c.scan() returns proper address

Asked 2021-May-26 at 22:27

I am currently using an SRF-10 sensor connected to an esp32. It's being powered by 5V and I am using a level converter to bring down the voltage to 3.3V to be able to use it on the esp32. Both the SCL and SDA have a 1.8K pull up resistor as recommended on the datasheet. I have written the following script to try to get a read from the sensor. I am not entirely sure if it is correct but soon as it reaches line 16 I get an error saying [Errno 19] ENODEV. Eveything I could find suggests that the i2c connection isn't working properly but when I run i2c.scan() it returns the sensor address so I am guessing connections aren´t the problem.

mkfs.vfat: unable to open {partition}: No such file or directory (command succeeds, but throws this error and blocks rest of script)

Asked 2021-May-21 at 03:38

Update: I got this working but am still not 100% sure why. I've appended the fully and consistently working script to the end for reference.

I'm trying to script a series of disk partition commands using sgdisk and mkfs.vfat. I'm working from a Live USB (NixOS 21pre), have a blank 1TB M.2 SSD, and am creating a 1GB EFI boot partition, and a 999GB ZFS partition.

Everything works up until I try to create a FAT32 filesystem on the EFI partition, using mkfs.vfat, where I get the error in the title.

However, the odd thing is, the mkfs.vfat command succeeds, but throws that error anyway and blocks the rest of the script. Any idea why it's doing this and how to fix it?

It may take time for kernel to be notified about partition changes. Try calling partprobe before mkfs, to request kernel to re-read the partition tables.

TestBench I2C Slave SDA won't go low

Asked 2021-May-17 at 17:21

I'm trying to write an I2C Slave and test it in isolation.

I have a simulation that should be pulling SDA low when write_ack is high (Also highlighted by the red dots). However, you can see that SDA remains the same.

Part of me thinks it's to do with the way I'm testing with the force methods and the delays.

Any help appreciated.

I have found the keyword release which seems to help.

ANSWER

Answered 2021-May-17 at 17:20

Instead of using force, a more conventional approach is to add a tristate buffer to the testbench, just like you have in the design.

For SDA, create a buffer control signal (drive_sda) and a testbench data signal (sda_tb). Use a task to drive a byte and wait for the ACK.

Since SCL is not an inout, there is no need for a pullup, and it can be directly driven by clk.

TestBench I2C SDA won't go low

I'm writing my first ever I2C program in Verilog and I'm struggling with the TestBench.

I want to test the I2C Slave in isolation, but I'm unable to set different SDA values: SDA is always 1, or X.

Am I going about testing the wrong way? My thoughts are I should be able to on every clock, set the SDA and see what happens.
