  • Inserting data into a Database

    - by Erebus
    SO I'm making a "basic" login file where a person logs in and the data that person entered on that form gets transfered to another form aka my database/table. I think the problems is here but I'll post the rest of the code. CREATE FUNCTION dbo.Function4 ( parameter1 int = 5, parameter2 datatype ) RETURNS Table1 TABLE (UserName, Password, Password_Confirmation, Assets) AS BEGIN INSERT INTO Table1 (UserName, Password, Password_Confirmation, Assets) VALUES (a,b,c,d); /*SELECT ... FROM ...*/ RETURN END This is the Login Form using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace Login_Basic { public partial class Form2 : Form { public Form2() { InitializeComponent(); } Form3 Delta = new Form3(); private void label3_Click(object sender, EventArgs e) { } private void Form2_Load(object sender, EventArgs e) { this.Hide(); } private void textBox6_TextChanged(object sender, EventArgs e) { } private void textBox6_KeyPress(object sender, KeyPressEventArgs e) { int i = Convert.ToInt32(e.KeyChar); if (!(Char.IsDigit(e.KeyChar) || Char.IsControl(e.KeyChar) || (e.KeyChar == '.' && this.Text.Contains(".") == false))) e.Handled = true; } private void button1_Click(object sender, EventArgs e) { Delta.Show(); //if (textBox3.Text.Equals("")) //{ // MessageBox.Show("Please enter your username"); //} //else //{ // this.Hide(); //} // if (textBox4.Text.Equals("")) //{ // MessageBox.Show("Please enter your password"); // } // else //{ // this.Hide(); // } // if (textBox5.Text.Equals("")) // { // MessageBox.Show("Please re-enter your password"); // } // else // { // this.Hide(); // } //if (textBox6.Text.Equals("")) //{ // MessageBox.Show("Please enter your amount"); // // } // else // { // this.Hide(); // } } private void button3_Click(object sender, EventArgs e) { this.Hide(); } private void textBox3_TextChanged(object sender, EventArgs e) { } private void textBox4_TextChanged(object sender, EventArgs e) { } private void textBox5_TextChanged(object sender, EventArgs e) { } private void panel2_Paint(object sender, PaintEventArgs e) { /*if (textBox3.Text.Equals("") && textBox4.Text.Equals("") && textBox5.Text.Equals("") && textBox6.Text.Equals("")) { button1.Enabled = false; } else { button1.Enabled = true; }*/ } } } Here's a "Pic" of my database http://s299.photobucket.com/albums/mm305/krsimms123/Code.jpg Thanks in advance (I'll try and check this every few hours so I can help explain anything)

  • C/C++ efficient bit array

    - by aaa
    hi. Can you recommend efficient/clean way to manipulate arbitrary length bit array? right now I am using regular int/char bitmask, but those are not very clean when array length is greater than datatype length. std vector<bool> is not available for me. thanks

  • Asyncronous While Loop?

    - by o7th Web Design
    I have a pretty great SqlDataReader wrapper in which I can map the output into a strongly typed list. What I am finding now is that on larger datasets with larger numbers of columns, performance could probably be a bit better if I can optimize my mapping. In thinking about this there is one section in particular that I am concerned about as it seems to be the heaviest hitter: while (_Rdr.Read()) { T newObject = new T(); for (int i = 0; i <= _Rdr.FieldCount - 1; ++i) { PropertyInfo info = (PropertyInfo)_ht[_Rdr.GetName(i).ToUpper()]; if ((info != null) && info.CanWrite) { info.SetValue(newObject, (_Rdr.GetValue(i) is DBNull) ? default(T) : _Rdr.GetValue(i), null); } } _en.Add(newObject); } _Rdr.Close(); What I would really like to know, is if there is a way that I can make this loop asyncronous? I feel that will make all the difference in the world with this beast :) Here is the entire Map method in case anyone can see where I can make further improvements on it... IList<T> Map<T> // Map our datareader object to a strongly typed list private static IList<T> Map<T>(IDataReader _Rdr) where T : new() { try { Type _t = typeof(T); List<T> _en = new List<T>(); Hashtable _ht = new Hashtable(); PropertyInfo[] _props = _t.GetProperties(); Parallel.ForEach(_props, info => { _ht[info.Name.ToUpper()] = info; }); while (_Rdr.Read()) { T newObject = new T(); for (int i = 0; i <= _Rdr.FieldCount - 1; ++i) { PropertyInfo info = (PropertyInfo)_ht[_Rdr.GetName(i).ToUpper()]; if ((info != null) && info.CanWrite) { info.SetValue(newObject, (_Rdr.GetValue(i) is DBNull) ? default(T) : _Rdr.GetValue(i), null); } } _en.Add(newObject); } _Rdr.Close(); return _en; }catch(Exception ex){ _Msg += "Wrapper.Map Exception: " + ex.Message; ErrorReporting.WriteEm.WriteItem(ex, "o7th.Class.Library.Data.Wrapper.Map", _Msg); return default(IList<T>); } }

  • Java keep printing a new line in my recursive method

    - by Abra Grace Libretto White
    I am trying to write a recursive method to print n number of asteriks in a line and create a new line at the end. So, TriangleOps.line(5); would print ***** This is the code I wrote: public static void line (int n){ if(n>0){ System.out.println("*"); line(n-1); }} instead it prints * * * * * with a lot of space at the end. Can anyone tell me how to remove the line breaks?

  • Why is T() = T() allowed in C++?

    - by Rimo
    I believe the expression T() creates an rvalue (by the Standard) However the following code compiles (at least on gcc4.0) class T {... }; int main() { T() = T(); } I know technically this is possible because member functions can be invoked on temporaries and the above is just invoking the operator= on the r-value temporary created from T(). But conceptually this is like assigning a new value to an r-value. Is there a good reason why this is allowed?

  • Implicit conversion causes stack overflow

    - by user44242
    The following code snippet worked perfectly, then after some code changes in different files, I've started getting stack overflows resulting from recursive invocation of the implicit conversion. Has this ever happened to anyone, and if so what's the fix. implicit def comparable2ordered[A <: Comparable[_]](x: A): Ordered[A] = new Ordered[A] with Proxy { val self = x def compare(y: A): Int = { self.compareTo(y) } }

  • Convert bit to boolean string in HyperLinkField.DataNavigateUrlFormatString

    - by abatishchev
    I have a asp:GridView with a HyperLinkField. It's DataNavigateUrlFormatString property is set to View.aspx?id={0}&isTechnical={1} Select command of appropriate SqlDataSource returns columns of type INT and BIT (from SQL Server 2008). So displayed string becomes something like View.aspx?id=1&isTechnical=1. But I want to display isTechnical=true|False, i.e. Convert.ToBoolean(row["isTechnical"]).ToString().ToLowerInvariant(). How to implement such conversion in page markup?
