How come when I put the label text setting here:
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.Run (new Form1());
}
private void LoadInfo()
{
label1.Text = DateTime.Now.To String();
}
The form comes up but no text is displayed?
If I put the label text setting here:
namespace Viewer1
{
/// <summary>
/// Summary description for Form1.
/// </summary>
public class Form1 : System.Windows. Forms.Form
{
private System.Windows. Forms.Label label1;
/// <summary>
/// Required designer variable.
/// </summary>
private System.Componen tModel.Containe r components = null;
public Form1()
{
//
// Required for Windows Form Designer support
//
InitializeCompo nent();
label1.Text = DateTime.Now.To String();
Then it works fine.

Hi. If you open up the region that VS.NET creates for you called "Windows
Form Designer generated code", then you will see all of the initialization
of the controls that needs to take place BEFORE your loading of the text.
InitializeCompo nent() in your Form contstructor will do this needed
initialization. You need to do your own property setting of the controls
AFTER InitializeCompo nent().
-- Alan
Hi,
I recommend you two places where to put your controls customizations:
1- Right after the InitializateCom ponent () call in the constructor
2- the Form_Load event.
DO NOT MODIFY THE InitializateCom ponent () method, never touch it.
Pd:
In your first example when you call LoadInfo() ?
Cheers,

I understand what you say. I thought the same.
But, in an earlier program that I wrote, I have set labels to text values
right after the MAIN () {Application.Ru n(new form1())}
i.e.
[STAThread]
static void Main(string[] args)
{
Application.Run (new Form1());
}
private string folderName1, fileName1 ;
public void button1_Click(o bject sender, System.EventArg s e) //open folder
selection.
{
DialogResult result = folderBrowserDi alog1.ShowDialo g();
if(result == DialogResult.OK ) //folder selected
{
folderName1 = folderBrowserDi alog1.SelectedP ath;
label1.Text = folderName1 ;
Or is this different in some way?
TIA

In the first example your function LoadInfo() would do what you want - but it is
never called! In the second your label initialization is done in the form's
constructor, which does get called when the app starts. A combination which
would also work would be:
public Form1()
{
//
// Required for Windows Form Designer support
//
InitializeCompo nent();
LoadInfo();
. . . etc.

Thank you.
What you added helped me understand more of what Ignacio said.
Now I'll know to call my methods. :-)
I'm not real clear on my second example but I assume the button_click in the
"windows form designer generated code" does the calling after initialization.

Yes, this snippet that you show is setting the label text in a button click
event handler. The InitializeCompo nent() had already been called earlier in
your Form1 constructor. (The constructor is called in the Run(new
Form1())).
-- Alan
In your second example, the button_click is an event handler, and so is
called when a button is clicked on the form ...
you will have the following in the code for your second example ...
public class Form1 : System.Windows. Forms.Form
{
private Button button1;
/* other declarations omitted for berevity */
private void InitializeCompo nent()
{
button1 = new System.Windows. Forms.Button();
button1.Click += new System.EventHan dler(this.butto n1_clicked);
/* other initialisations omitted for berevity */
}
/* other members omitted for berevity */
}
