Answer 1

あなたのエラーは、この行に明確であるButton2.Clickを処理

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 & "'"** 

あなたが持っていますUpdateの文から()を削除するには、以下の

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 & "'" 

Answer 2

削除のようになりあなたのオープンとクローズの括弧：

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 & "') 

答え

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 & "'
