No, the ShowDialog will create a mode dialog, but the Show will create a non-mode dialog. The mode dialog means that others form can not be operated.

thank you for your good answer just exactly what i wanted
and you learned me the terminology
but in real you told me the terms modal, and non-modal exactly vice versa
Show() will create a non-modal and ShowDialog() will create a modal
if you are in shake just check the modal dialog in the wikipedia 
thanks a lot

I wanted to close a previous form after calling the next form. How do i do that?
I have many form in my application. When i exit the application using the following code all the forms are closed one by one. Instead i want to close the previous form after calling the next form in order to avoid the closing of all the forms after exit. Please help.
DialogResult result = MessageBox.Show("Do you want to exit?", "Exit-Window", MessageBoxButtons.OKCancel, MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1);
if (result == DialogResult.OK)
Application.Exit();
I have tried with the following code but the application exits automatically.
The code is written on the command button on Form1.
private void button1_Click(object sender, EventArgs e)
{
Form2 frm2 = new Form2();
frm2.Show();
this.Close();
}
|
|
|
|
|
The reason why the application exits automatically is that the entry point for it is located in a class usually called Program.cs that has the following code:
static void Main() {
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
The last line (Application.Run(new Form1())), starts a message loop that ends as soon as the main form is closed (new Form1()), what causes the end of the application.
To prevent the application from exiting I've found two possible solutions based on your original idea:
1. The first one is not to close the main form but to hide it:
private void button1_Click(object sender, EventArgs e)
{
Form2 frm2 = new Form2();
frm2.Show();
this.Hide();
}
2. The second is to invoke the Application.Run() overload that doesn't take a Form as parameter but an ApplicationContext. This object (that always exist), implements an overridable method called OnMainFormClosed() that is responsible of shutting down the application when the main form is closed. To prevent this from happening, you can derive a new class from it that substitutes the original method by another that does nothing:
//New class.
class ApplicationContextOwn : ApplicationContext {
//Overriden method does nothing
protected override void OnMainFormClosed(object sender, EventArgs e) {
}
}
static class Program {
public static ApplicationContext ac = new ApplicationContext();
///
/// The main entry point for the application.
///
[STAThread]
static void Main() {
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
//The application is started using an instance of the new class.
ApplicationContext ac = new ApplicationContextNew();
ac.MainForm = new Form1();
Application.Run(ac);
}
}
Hope this helps.

The application is closing because you're calling the main form that was started by the application.

This is to read the tag line by line.
using System.Xml;
...
...
...
XmlTextReader reader = new XmlTextReader ("reader.xml");
while (reader.Read())
{
switch (reader.NodeType)
{
case XmlNodeType.Element: // The node is an element.
Console.Write("<" + reader.Name);
Console.WriteLine(">");
break;
case XmlNodeType.Text: //Display the text in each element.
Console.WriteLine (reader.Value);
break;
case XmlNodeType.EndElement: //Display the end of the element.
Console.Write("</" + reader.Name);
Console.WriteLine(">");
break;
}
}
Console.ReadLine();

use an XmlDocument[^] and the SelectNodes[^] method to search for specific nodes. This[^] article has a nice cheat sheet of the XPath syntax for searching for nodes.

Hi,
I programatically have to create a windows application in which one windows schedular is there which is for calling a webmethod in a webservice...
how to create such program to call webmethod using windows schedular in C#.net.
Pls help me in this...
Advanced Thanks,

There is nothing special about Windows scheduler. You call the web methods as you usually would, in a regular app, then schedule your app to run using Windows scheduler.
If you don't know to create or consume web methods, use Google or buy a book.

Hi,
I am trying to enable the keypress event for 'F5' key to refresh my form... Because I found that the normal KeyPress event does not work for function keys, I tried overriding the PreProcessMessage() function, as follows :
public override bool PreProcessMessage(ref Message msg)
{
try
{
if (msg.Msg == WM_KEYDOWN)
{
Keys keyCode = (Keys)msg.WParam & Keys.KeyCode;
if (keyCode == Keys.F5)
{
//code
}
}
return PreProcessMessage(ref msg);
}
catch (Exception ex)
{
throw;
}
}
But the control never gets into this method... Can anyone help me fix this?
Thanks in advance,
ramzg

You should change the keypreview property to true of form. if it is set to false.
|

Hi S a n d y,
I tried what had posted... But still, the control doesnt get inside the method... Do i have to do something else?
Thanks,

You use the wrong syntax!, the correct syntax is
protected override bool ProcessCmdKey(
ref Message m,
Keys keyData
)
Try this:
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
if (keyData == Keys.F5)
{
MessageBox.Show("F5 pressed!");
}
return base.ProcessCmdKey(ref msg, keyData);
}
Hope this help.
