Hello everyone I'm just learning C# and currently I'm working with Bank Simulation using SQL database.

Problem: I still can't access or display the specific account number's data into a form.

Need: is when I input account number into text box and click a button a new form will show and display all the information that has this account number.

here is my code:

C#

private void btnOpen_Click(object sender, EventArgs e)
{
    con = new System.Data.SqlServerCe.SqlCeConnection();
    con.ConnectionString = "Data Source=C:\\Users\\Lovette\\Documents\\MyFiles\\ETEEAP\\MODULE-1 C#\\Bankdatabase\\BankAccount.sdf";

    comd = new SqlCeCommand("SELECT * From tbl_bankaccount WHERE AccountNumber='" + tbAccountNum.Text.Trim() + "'", con);
    con.Open();

    reader = comd.ExecuteReader();

    clientRecordForm clientRecords = new clientRecordForm(this);

    while (reader.Read())
    {
        tbAccountNumPR.Text = reader.GetValue(0).ToString();
        tbFirstName.Text = reader.GetValue(1).ToString();
        tbMiddleName.Text = reader.GetValue(2).ToString();
        tbLastName.Text = reader.GetValue(3).ToString();
        tbEmployer.Text = reader.GetValue(4).ToString();
        tbBusinessAdd.Text = reader.GetValue(5).ToString();
        tbHomeAdd.Text = reader.GetValue(6).ToString();
        tbContactNum.Text = reader.GetValue(7).ToString();
        tbMoney.Text = reader.GetValue(8).ToString();
        clientRecords.ShowDialog();
    }
    con.Close();

Just like you are doing? Your "problem" statement is not a problem at all. You have to tell us what the problem is.

Oh my apology for that, problem here is I still can't see the specific data that I wanted to access for the specific Account Number.

All I need is when I input account number in the textbox called tbAccountNumber and a button called btnOpen a new form (clientformofdata) will show and display all the information that has this account number.

Okay so how exactly is that a problem? You are creating the form, but not doing anything with it, and then showing it. Where do you think that your clientRecordForm is getting its data from?

I'm getting the data on the Sql database called "tb_bankaccount".
I have SQL database and has 9 columns(AccountNumber, Firstname,middlename, lastname, employer, businessaddress, homeaddress, contactnumber and moneyinBank) and I have 5 data on it..

Yes I see that. You are not understanding me, I suppose. You are creating a form but you are not doing anything with your data to show it on the form.... So, again, where is it that you think that the form you are creating, clientRecordForm, is getting its data from to show?

Hello ThePhantomUpvoter im getting the data from my first form where I can enter the account number. This form has only textbox and a button.

Hii can not see any parameter that you sent to db to search the numbers
do you mean you don't know how to create a search store procedure in sql or how to work with a search procedure from sql ?

Lovette 10-Sep-13 6:18am

Hello doostl, actually I know how to search on DB but i can ONLY show this in a MESSAGEBOX but not in a form.

design ur first windoe form with a txtbx and btn tp enter Account No.
On btn_click event write the code to call second form which will open now.

form2 obj = new form2();
obj.AccountNo = txtbx.text; // here AccountNo is a publicly defined string variable in form2
obj.show();

now write your query to retrieve all information based on that AccountNo
and show them in different controls.

Instruction:- Better to use dataset than dataReader.
