 C++ ListViewda Arama Yapmak ve Aranan Kayıt Bilgilerini TextBoxta Göstermek

 

 

Merhaba arkadaşlar bu makalemizde C++ da ListView nesnesinde My Sql veritabanındaki verilerin gösterimini sağlayacağız. TextBox a girileni ListView da arayacağız. Bulunan kayıt satırının arka plan ve yazı rengini değiştireceğiz. Bulunan kayıt bilgilerini TextBox ta göstereceğiz. 

C++ da Windows Form nasıl ekleriz? Konusunu daha önceki makalede anlatmıştım. Önceki makaleye ulaşmak için Buraya tıklayabilirsiniz. 

İlk önce Manage Nuget Packages browser kısmından libmysql i kurunuz. Daha sonra References kısmına sağ tıklayalım. Add Referencesi seçip tıklayalım. Açılan Add references penceresnde MySql.Data yı seçip, OK butonuna tıklayalım.

Biz bu örneğimizde MySql de book şemasındaki worldclassics tablosuna bağlanacağız. (Schema:book)

 

MySql veritabanımızı Şekil 1 deki gibi oluşturuyoruz. 

Formumuzu çalıştırdığımızda My Sql Veritabanımızdaki dbemployee tablomuz DataGridView nesnesinde aşağıdaki gibi görülecektir.
