你的错误显然在这一行

cmd.CommandText = "UPDATE Firma  SET (Sektor = '" & ComboBox1.Text & "', Tip = '" & ComboBox2.Text & "', Telefon = '" & MaskedTextBox1.Text & "', Web = '" & TextBox2.Text & "', Adres = '" & RichTextBox2.Text & "', OSB = '" & ComboBox3.Text & "', PR = '" & ComboBox4.Text & "', Sehir = '" & ComboBox5.Text & "', Ulke = '" & ComboBox6.Text & "', Note = '" & RichTextBox1.Text & "', Durum = '" & ComboBox7.Text & "', Email ='" & TextBox3.Text & "') WHERE Firma = '" & ComboBox8.Text & "'"**

您必须从()语句中移除Update，如下所示

cmd.CommandText = "UPDATE Firma  SET Sektor = '" & ComboBox1.Text & "', Tip = '" & ComboBox2.Text & "', Telefon = '" & MaskedTextBox1.Text & "', Web = '" & TextBox2.Text & "', Adres = '" & RichTextBox2.Text & "', OSB = '" & ComboBox3.Text & "', PR = '" & ComboBox4.Text & "', Sehir = '" & ComboBox5.Text & "', Ulke = '" & ComboBox6.Text & "', Note = '" & RichTextBox1.Text & "', Durum = '" & ComboBox7.Text & "', Email ='" & TextBox3.Text & "' WHERE Firma = '" & ComboBox8.Text & "'"
