See more:

here is the firebird code

public bool InsertNewCarsFees(structNewCarFees ncf)
		{
			fbConnection.Open();
			FbCommand fbCommand = ncf.CreateInsertCommand();
			fbCommand.Connection = fbConnection;
			try
			{
				fbCommand.ExecuteNonQuery();
				NewCarFees.Add(ncf);
				fbCommand.Dispose();
				fbCommand = null;
				fbConnection.Close();
				return true;
			}
			catch
			{
				fbCommand.Dispose();
				fbConnection.Close();
				return false;
			}
		}

What I have tried:

I am new to C# and MySql- still learning

public bool InsertNewCarsFees(StructNewCarFees ncf)
      {

          qmConnection.Open();
          MySqlCommand cmd = ncf.CreateInsertCommand();
          cmd.Connection = qmConnection;
          try
          {
             cmd.ExecuteNonQuery();
              newCarFees.Add(ncf);
              cmd.Dispose();
              cmd = null;
              qmConnection.Close();
              return true;
          }
          catch
          {
             cmd.Dispose();
              qmConnection.Close();
              return false;
          }
      }

This is the error message relating to ncf.CreateInsertCommand

Severity	Code	Description	Project	File	Line	Suppression State
Error	CS7036	There is no argument given that corresponds to the required formal parameter 'qmConnection' of 'StructNewCarFees.CreateInsertCommand(MySqlConnection)'	QMData	C:\Users\quote\Documents\QM Online App\QMData\ClassQM.cs	125	Active

I think you cannot use ncf.CreateInsertCommand for MySQL, take a look at the answer here: C# how to insert data to mysql using C#? - Stack Overflow[^]

Your CreateInsertCommand method requires a parameter of type MySqlConnection. It looks like you have one hanging about:

C#

qmConnection.Open();
MySqlCommand cmd = ncf.CreateInsertCommand(qmConnection);

Depending on the implementation of that method, you might not need to set the cmd.Connection property on the following line.
