Because you can't modify data in the app.config programatically. If you want user-specific data to be saved, you have to use the Settings object.

Your code works for me.
If you're looking for changes in your App.config, you're not going to find them there.
The changes are in the actual runtime configuration file named yourappname.exe.Config,
which will be in the same folder as the exe.

Hi everyone,now I have a winform Form1,in Form1,there is a TextBox1,and its Text is "abcd".
In the other project,I want to get the Text of TextBox1,as below:
Assembly assembly = Assembly.LoadFrom(@"ClassLibrary1.dll");
Type[] types = assembly.GetTypes();
FieldInfo[] fis;
System.Windows.Forms.TextBox tb;
for (int i = 0; i < types.Length; i++)
{
fis = types[i].GetFields(BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic);
for (int j = 0; j < fis.Length; j++)
{
if (fis[j].FieldType == typeof(System.Windows.Forms.TextBox))
{
tb = fis[j].GetValue(Activator.CreateInstance(types[i]))as System.Windows.Forms.TextBox;
Console.WriteLine(tb.Text);
}
}
}
Console.Read();
But I have to create a instance "Activator.CreateInstance(types[i]))".Are there any ways that I can get the Text without create a Form1 instance?
Anyone who can help it would be appreciated.

Since the textbox is a member of Form1, you need to instantiate Form1 for getting access to text box.

That would be like asking for the colour of a car that doesn't exist. You know that cars have colours - but you the colour doesn't exist without the car.

Hai
Me with C#.net I want to make a text box to accept only numbers and decimal points(decimal point only once), so I tried to make a user control and is working fine except one problem. If if select all the data in the text box and try to enter a new value decimal point will not accept until I press the backspace. My user control code is a follows
string i;
int f;
public string Text
{
get
{
return NMTextBox.Text;
}
set
{
NMTextBox.Text = value;
}
}
private void NMTextBox_KeyPress(object sender, KeyPressEventArgs e)
{
try
{
string numaric = NMTextBox.Text;
for (int j = 0; j < numaric.Length; j++)
{
char myChar = numaric[j];
}
if (NMTextBox.Text == "")
{
f = 0;
}
if (e.KeyChar.ToString() == ".")
{
++f;
if (f >= 2)
{
e.Handled = true;
}
}
if (i == "8")
{
f = 0;
for (int j = 0; j < numaric.Length - 1; j++)
{
if (numaric[j].ToString() == ".")
{
++f;
}
}
}
if (e.KeyChar.ToString() != "." && Char.IsNumber(e.KeyChar) != true)
{
if (i != "8")
{
e.Handled = true;
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.StackTrace, ex.Message.ToString());
}
}
private void NMTextBox_KeyDown(object sender, KeyEventArgs e)
{
i = e.KeyValue.ToString();
}
Thanks & Regards

There are lots of tools for this, but I assume no one is perfect. Do it manually.
C isn't that hard: void (*(*f[])())() defines f as an array of unspecified size, of pointers to functions that return pointers to functions that return void

First just write in simple english what this code does and then think how to write that in C#
I think that's the simplest method

The Name of the node? Could that be what the Name[^] property is for?

If you are going to include XML in your post either manually escape the XML characters or check the "Ignore HTML tags in this message (good for code snippets)" box for the post (below the smilies and above the submit button)
If you are using .NET 3.5 there are new and better classes for querying XML.

If node a and des have attribute called "name" then you can get the value of that attribute by following
foreach (XmlNode node in List)
{
int i = int.Parse(node["a"].Attributes["name"].Value;);
des[i]= node["des"].Attributes["name"].Value;
}

Hi
I want to do a project where I need to calculate the intersection of the two cubes but I don't now how i can calculate the volume of this intersection. This is the project
Create a small web application that allows a user to enter the dimensions and coordinates of two cubic objects in a 3-dimensional space. Once the information has been entered, the web application should calculate if the two cubes intersect, and if so, what the volume of the shared space is.
Note, the coordinates specify the CENTER of the cube!
Sample Data:
Cube A: Size = 5m x = 10m
y = 10m
z = 0
Cube B: Size = 2m x = 9m
y = 9m
z = 1m
Answer: Do the cubes intersect? What is the volume of the shared space?

Guys,
I am trying to save the hidden panel contents to an image using GDI+.
I do not want to resize the panel to show all the contents and then save it.
I would like to keep the panel at the default size and save all the hidden contents without scrolling.
Thx.

Image image = this.panel1.BackgroundImage;
image.Save("1.jpg");
