Hi ,
In the Insert button i have used the follwing coding,
cmd = New OleDb.OleDbCommand("insert into emp values( ' " & TextBox1.Text & " ' , " & TextBox2.Text & "
Textbox 1 has String and Textbox 2 has Numeric data.
con.Open()
cmd.ExecuteNonQuery
Connection string "con" declared Globally.
By executing the code i got error like, "OleDb Exception was UnHandled by the user code"
" Line 1: Incorrect syntax Error "
After that i changed the code,
Dim Ssql as String = "insert into emp(nam,regno)values(@nam,@regno)"
cmd = New SqlCommand(Ssql,con)
Dim Op1,Op2 as SqlParameter
Op1 = cmd.Parameter("@nam",SqlDbType.Char))
Op2 = cmd.Parameter("@regno",SqlDbType.Char))
Op1.Direction = ParameterDirection.Input
Like wise for Op2 also.
Op1.Value = TextBox1.Text
Op2.Value = Textbox2.Text
cmd.ExecuteNonQuery
So by executing the above code, there is no error but same data's are inserted again and again, like if the textbox1 = preethi, textbox2 = 2001 are the data alredy present. then if i
clear those data by the "ADDNEW button" and if i insert new data , the new data are not stored, again that preethi and 2001 are stored.
i donno what will be the mistake..........!
