Hi Sathish,
This is a nice topic.Let me start with a question.How can I programmatically maximize or minimize a form?

Hi Deeban,
Use the form's WindowState property for minimizing and maximising the forms.
//minimize
this.WindowState = System.Windows.Forms.FormWindowState.Minimized;

//maximize
this.WindowState = System.Windows.Forms.FormWindowState.Maximized;

Hi sathish,
Thats simple and superb.OK How can I display a interactive pop up when the user closes the form?

Hi ,

You can listen to the Form's Closing event, where you can display a MessageBox as show below:

[C#]
private void Form1_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
if (MessageBox.Show("Do you want to close the application?", "Close Application", MessageBoxButtons.YesNo) == DialogResult.No)
e.Cancel = true;

}
[VB.NET]
Private Sub Form1_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs)
If MessageBox.Show("Do you want to close the application?","Close Application",MessageBoxButtons.YesNo) = DialogResult.No Then
e.Cancel = True
End If

End Sub

Hi sathish,
You know the apearance of the form and controls plays a major role in the applications.So,I need to know How to center my form?Could anyone help?

Hi Deeban,
Yes.You are absolutely right.You can set the Form's StartPosition property to CenterScreen to achieve this.

Hi sathish,
I tried your idea.Its working.Now I am overcoming another doubt.When we resize the form,the whole arrangement of controls gets collapsed.So,I dont want to allow users from resizing my forms.Do you have any idea how to do this?

Hi Deeban,
You can prevent the users from resizing your form by setting the FormBorderStyle to FixedDialog and setting the MaximizeBox property to false.

Hi Sathish,
I am a newbie.And the first thing that strikes me to learn the display and appearance of the application.Thats why I am asking a lot of questions on this one.ok How do I programmatically set an image as Form's Icon ?

Hi Deeban,
You could do so as shown in the code below :
[C#]
Form form1 = new Form();
Bitmap bmp = imageList1.Images[index] as Bitmap;
form1.Icon = Icon.FromHandle(bmp.GetHicon());

[VB.NET]
Dim form1 As Form = New Form()
Dim bmp As Bitmap = imageList1.Images(index) as Bitmap
form1.Icon = Icon.FromHandle(bmp.GetHicon())
