DroppedDown property is not supported in CE Framework. I need it for Pocket PC project.

Hello,

Normaly the correct usage of anchor and dock property from the controls should solve this problem.
May you can give a more detailed example.

All the best,

Martin

Hi,

When you set the size for each and every control, give in terms of percentage(%) instead of giving the exact size

Passing Values between Forms in .NET 1.x with C# and VB.NET examples[^]

25-Jan-07 1:06

Hello,

Actually scale is a method from the control class, so every Control which inherits from System.Control (TextBox, Button, ...) has it.

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.

plz help me?

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; Smile | :)

How can I get Combobox Selected ValueMember

24-Jan-07 22:26

Sanjib Raj wrote:

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...

It's the SelectedIndex property of the combobox.

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()

dataminers24-Jan-07 22:47

24-Jan-07 22:47

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");
