Boa Tarde

Gostaria de saber como faço para ler os dados de uma base de dados SQL, para TextBox :wallbash:

Obrigado


A informática chegou para resolver problemas que antes não existiam

Quem ri por último é porque está conectado a 52 Kbs.

M6

Fazes a query para obter os dados, lês a informação do cursor e colocas a informação lida na textbox.


10 REM Generation 48K!
20 INPUT "URL:", A$
30 IF A$(1 TO 4) = "HTTP" THEN PRINT "400 Bad Request": GOTO 50
40 PRINT "404 Not Found"
50 PRINT "./M6 @ Portugal a Programar."

Podias pesquisar mais um pouco....

Mas cá vai:

Imports System.Data.SQLClient
Public sub ligacao
    Dim con As New SqlConnection(Metes aqui a connectionString)
    Dim comando as new SqlCommand("select campo from tabela",con)
    con.Open()
    TextBox1.Text = comando.ExecuteScalar()
    con.Close()
End Sub

PS: se tiveres dúvidas na connectionString, diz.

PS2: é executado o método ExecuteScalar, devido ao facto de teres de enviar um e apenas um valor da BD.
