Draw a circle in the VB window, change the position of the circle through different xy inputs, and control the circular movement through the keyboard

VB draws a circle in the window and inputs different xy to change the coordinates of the circle and make the circle receive keys

Private Sub Picture1_KeyDown(KeyCode As Integer, Shift As Integer)

If KeyCode = vbKeyRight Then

Picture1.Left = Picture1.Left 100

End If

If KeyCode = vbKeyLeft Then

Picture1.Left = Picture1.Left - 100

End If

End Sub

Private Sub Picture1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)

Picture1.Circle (X, Y), 300

End Sub

You need to control your circle to move inside a container

Write a program to input three numbers x y z when you click the form and display them in the form in order from small to large

Private Sub Command1_Click()

Dim a As Integer, b As Integer, c As Integer

Dim max As Integer, min As Integer

a = Val(InputBox("Input the first integer", "Input"))

b = Val(InputBox("Enter the second integer", "Input"))

c = Val(InputBox("Enter the third integer", "Input"))

max = a

If b >max Then max = b

If c >max Then max = c

min = a

If b If c

Print max, a b c - max - min, min

End Sub

Design a window form application to randomly input a series of positive characters from the text box

Create a rich textbox, and enter integers separated by commas ",", such as 123, 45, 67, 89, and then

Sort button code

private void button1_Click(object sender, EventArgs e)

{

string str = richTextBox1.Text.Replace(＂＂,＂＂).TrimEnd(new char[]{','});

if (!string.IsNullOrEmpty(str.Trim(("1234567890,").ToCharArray())))

{

MessageBox.Show("Input data is incorrect!");

return;

}

string[] strs = str.Split(new char[] { ',' });

int[] lint = new int[strs.Length];

for (int i = 0; i

lint[i] = int.Parse(strs[i]);

Array.Sort(lint);

richTextBox1.AppendText("\r\nThe order from small to large is:\r\n");

foreach (int i in lint) richTextBox1.AppendText(i ＂,＂);

}

Visual Basic Programming 1 Automatically maximize the window after the program runs 2 Form title xxxxxx

Private Sub Command1_Click()

End

End Sub

Private Sub Form_Click()

n = CInt(InputBox("Please enter an odd number", "Data input"))

Print

For i = 1 To n

Print Tab(51 - i);

For j = 1 To 2 * i - 1

Print Trim(Str(n Mod 10));

Next j

Print

Next i

For i = n - 1 To 1 Step -1

Print Tab(51 - i);

For j = 1 To 2 * i - 1

Print Trim(Str(n Mod 10));

Next j

Print

Next i

End Sub

Private Sub Form_Load()

Me.FontSize = 19

Label1.FontSize = 19

Me.WindowState = 2

Me.Caption = "xxxxxx"

Label1.Caption = "xxxx"

End Sub
