Hi all,
I have a peculiar problem in my application.
I have developed a .net windows application that interacts with a third party dll named Ltws32.dll to connect to the database HP9000 and fetch data.
I have been working with it since 3 months.
Application is completely developed and pakaged also.
Now, the first time i try to fetch data, the connection is aborting .
From the second attempt it is working fine.
This happens only the first time when the application is launched.
Another strange behavior is ,it happens only if i compile the application in release mode.In debug mode its working fine.
The connection to the database is getting established but when i try to send data to the open connection ,it fails.
What can be the reason?
Thanks.

Yes, it is possible. If you have two forms in the same application then on the button click event of form 2 u can write the code like
Form frm = new Form1("Hello") // Define overloaded constructor for Form1.
frm.ShowDialog();
In form1, simply do like
public Form1(string msg)
{
this.str = msg;
}
txtBox1.Text = this.str;

It is one of the basic things in Object Oriented programming.
just if you create Form2 from Form1 give a reference of form1 to form2 and have a public function in form1 that sets the text in the textBox, Vica versa

**TEST_TABLE
ID Name Surname
-- ---- -------
3 Jack Black
4 Marry Green
5 John Wall
I fill combobox like this;
comboBox1.ValueMember = "id";
comboBox1.DisplayMember = "name";
comboBox1.DataSource = obj; //obj is IList
So, combobox filled and show "Name"s.
How can I get selected value's ID from combobox.
For example, if I select "Marry" on the combobox, how can I get "4"?
Best Regards...

comboBox1.SelectedIndex is return selected value index number.
For example my Database (table) like this;
**TEST_TABLE
ID Name Surname
-- ---- -------
3 Jack Black
4 Marry Green
5 John Wall
If I fill the comboBox and I select the "Marry" So comboBox1.SelectedIndex return "1"
But I want to get ID. (I want to get "4" in this example).

comboBox1.SelectedValue.toString()
|
|
|
|
|
comboBox1.SelectedValue.toString() --> Its return class name.
This are not work;
Convert.ToInt32(comboBox1.SelectedValue)
(string)comboBox1.SelectedValue;
comboBox1.SelectedItem.ToString();
comboBox1["id"];
comboBox1.SelectedItem["id"];
comboBox1("id");
comboBox1.SelectedItem("id");
|
|
|
|
|
And this is not work;
try
{
object o = comboBox1.SelectedValue;
int i = Convert.ToInt32(o);
}
catch (Exception ex)
{
DataRowView o = (DataRowView) comboBox1.SelectedValue;
int i = Convert.ToInt32(o["id"]);
}
|
|
|
|
|
comboBox1.SelectedValue.ToString()
Works great! 
|
|
|
|
|
comboBox1.SelectedValue.ToString() is Return Namespace name and Class name

You said you are using DataBase..
See the code bellow this is what I used :
namespace C_TestProject
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent(); ' Contains
}
private void Form1_Load(object sender, EventArgs e)
{
this.dB1TableAdapter.Fill(this.dbTestDataSet.DB1);
}
private void button1_Click(object sender, EventArgs e)
{
if (comboBox1.SelectedIndex >= 0)
MessageBox.Show(comboBox1.SelectedValue.ToString());
}
}
}
// code Inside InitializeComponent()
this.components = new System.ComponentModel.Container();
this.comboBox1 = new System.Windows.Forms.ComboBox();
this.button1 = new System.Windows.Forms.Button();
this.dbTestDataSet = new C_TestProject.DbTestDataSet();
this.dB1BindingSource = new System.Windows.Forms.BindingSource(this.components);
this.dB1TableAdapter = new C_TestProject.DbTestDataSetTableAdapters.DB1TableAdapter();
((System.ComponentModel.ISupportInitialize)(this.dbTestDataSet)).BeginInit();
((System.ComponentModel.ISupportInitialize)(this.dB1BindingSource)).BeginInit();
this.SuspendLayout();
//
// comboBox1
//
this.comboBox1.DataSource = this.dB1BindingSource;
this.comboBox1.DisplayMember = "EmpName";
this.comboBox1.FormattingEnabled = true;
this.comboBox1.Location = new System.Drawing.Point(62, 29);
this.comboBox1.Name = "comboBox1";
this.comboBox1.Size = new System.Drawing.Size(121, 21);
this.comboBox1.TabIndex = 0;
this.comboBox1.ValueMember = "ID";
//
// button1
//
this.button1.Location = new System.Drawing.Point(62, 90);
this.button1.Name = "button1";
this.button1.Size = new System.Drawing.Size(121, 23);
this.button1.TabIndex = 1;
this.button1.Text = "button1";
this.button1.UseVisualStyleBackColor = true;
this.button1.Click += new System.EventHandler(this.button1_Click);
//
// dbTestDataSet
//
this.dbTestDataSet.DataSetName = "DbTestDataSet";
this.dbTestDataSet.SchemaSerializationMode = System.Data.SchemaSerializationMode.IncludeSchema;
//
// dB1BindingSource
//
this.dB1BindingSource.DataMember = "DB1";
this.dB1BindingSource.DataSource = this.dbTestDataSet;
//
// dB1TableAdapter
//
this.dB1TableAdapter.ClearBeforeFill = true;
//
// Form1
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(243, 229);
this.Controls.Add(this.button1);
this.Controls.Add(this.comboBox1);
this.Name = "Form1";
this.Text = "Form1";
this.Load += new System.EventHandler(this.Form1_Load);
((System.ComponentModel.ISupportInitialize)(this.dbTestDataSet)).EndInit();
((System.ComponentModel.ISupportInitialize)(this.dB1BindingSource)).EndInit();
this.ResumeLayout(false);

Dear Sirs,
I use Visual Studio .NET 2005 (Framework 2.0)
I use Tree-Tier architecture approach in my project, and I use NHibernate.
I get data in the Data Layer from database and initialize object.
In View Layer;
First of all I determine ValueMember and DisplayMember for ComboBox
comboBox1.ValueMember = "id";
comboBox1.DisplayMember = "name";
And determine DataSource for ComboBox. I get data in IList fromat from Data Layer.
comboBox1.DataSource = XYZ; //XYZ is a IList
Now, ComboBox list name, its OK. My problem is I get id when I select any name from combobox.
**FOR EXAMPLE:
TEST_TABLE
ID Name Surname
-- ---- -------
3 Jack Black
4 Marry Green
5 John Wall
I fill combobox like this;
comboBox1.ValueMember = "id";
comboBox1.DisplayMember = "name";
comboBox1.DataSource = obj; //obj is IList
So, combobox filled and show "Name"s.
How can I get selected value's ID from combobox.
For example, if I select "Marry" on the combobox, how can I get "4"?
Note: This ways not solve my problem.
Int32 i = Convert.ToInt32(comboBox1.SelectedValue);
Int32 i = (Int32)comboBox1.SelectedValue;
int i = (int)comboBox1.SelectedValue;
string test = (string)comboBox1.SelectedValue;
string deneme = comboBox1.SelectedItem.ToString();
object o = comboBox1.SelectedValue;
DataRowView o = (DataRowView) comboBox1.SelectedValue;
Best Regards...
