Need help with multiple MySqlDataReader in c#

[jinxy]

Hello, this is my code in visual c#:

namespace im_client
{
public partial class Form2 : Form
{
MySqlConnection conDatabase = new MySqlConnection ("Data Source=86.123.2 20.28;" +
"Persist Security Info=yes;" +
"UserId=chat;PW D=123;Port=3306 ;Database=im_ch at;");



System.Windows. Forms.Timer myTimer = new System.Windows. Forms.Timer();



public Form2()
{

InitializeCompo nent();



myTimer.Tick += new EventHandler(Ti merEventProcess or);
myTimer.Interva l = 1000;
myTimer.Start() ;
Application.DoE vents();

this.Text = Form1.usern+" - IM Chat";


}


private void TimerEventProce ssor(Object myObject, EventArgs myEventArgs)
{
populate();
arequest();
//addrequest();

}
public void populate()
{

MySqlCommand userlist_popula te = new MySqlCommand("S ELECT * FROM friendlist WHERE user=?user", conDatabase);
userlist_popula te.Parameters.A ddWithValue("?u ser", Form1.usern);

conDatabase.Ope n();

MySqlDataReader dataReader = userlist_popula te.ExecuteReade r();

if (dataReader.Has Rows)
{
this.listBox1.I tems.Remove("To add a friend press the + button");
while (dataReader.Rea d())
{

int index = this.listBox1.I tems.IndexOf(da taReader.GetStr ing(1));

if (index == -1)
{

this.listBox1.I tems.Add(dataRe ader.GetString( 1));

}


}

}
else
{
int index2 = this.listBox1.I tems.IndexOf("T o add a friend press the + button");
if (index2 == -1)
{
this.listBox1.I tems.Add("To add a friend press the + button");
}
}
dataReader.Clos e();
conDatabase.Clo se();


}

public void arequest()
{
MySqlCommand userlist_add = new MySqlCommand("S ELECT * FROM friendlist WHERE friend=?user AND invers='1'", conDatabase);
userlist_add.Pa rameters.AddWit hValue("?user", Form1.usern);
conDatabase.Ope n();
MySqlDataReader dataReader = userlist_add.Ex ecuteReader();
if (dataReader.Has Rows)
{
MessageBox.Show ("Test");
//while (dataReader.Rea d())
//{

// Form5 form5 = new Form5(dataReade r.GetString(0)) ;
//form5.Show();
//}

}


dataReader.Clos e();
conDatabase.Clo se();
}



The problem is that it says the connection is already opened. i've tried different conections, different names for the MySqlDataReader object instances, nothing worked.... any suggestions?

What do you mean when you say your connection is already open? Could you post the error/exception messages you receive?
