First of all, DateTimePicker have nothing to do with DateTime they are two seperate things.
Second, the problem is in your method,you see you have a method(deliveryTime_ValueChanged) and when this method is called or triggered it'll run the code inside of it (deliveryTime.MinDate = DateTime.Now.AddHours(1);) and the problem is that there's nothing to trigger your method which is changing the date of your dateTimePicker, it's like you want to see what's inside of a potato chips bag without opening the bag.
i recommend that you use a timer tick event like so:

private void timer1_Tick(object sender, EventArgs e)
{
   deliveryTime.Mindate = DateTime.Now.AddHours(1);
}

add a timer control and you can call it by Timer1.enabled = true;

Ok i get it now.

public static int[][] Puzzle(int[] numbers, int x) {

    int rows = 0,a = 0;
    for (int i = 0; i<numbers.length;i++){
           for (int j = 1;j>=i && j<numbers.length;j++){
               if (numbers[i] +numbers[j]==x){
               if (i!=j){
                   rows++;
               }}
    }} 

    int [][]b = new int [rows][2];
    for (int i = 0; i<numbers.length;i++){
           for (int j = 1;j>=i && j<numbers.length;j++){
                   if(numbers[i]+numbers[j] == x){
                                    if (i!=j){
                        b[a][0] = i;
                        b[a][1] = j;
                        a++;
                    }}
    }
    }return b; 
    }
}

Copy/paste the whole thing, and you are good to go.

In the picture; line 7 change it to:

for (int j = 1;j>i && j<numbers.length;j++){

Make sure it's the same code i posted, because there's no way you'll get a {0,0} in the output, or send me your final code and i'll take a look at it

Use Control.Parent = Panelx
example : button1.parent = panel1
the button1 is now attached to panel1, so that when you hide or move the panel the control in it(button1) will behave the same.

Ok in the inner loop, [j] should always be a one step ahead of [i]:

public static int[][] Puzzle(int[] numbers, int x) {

    int rows = 0,a = 0;
    for (int i = 0; i<numbers.length;i++){
           for (int j = 1;j>i && j<numbers.length;j++){
               if (numbers[i] +numbers[j]==x){
                   rows++;
               }
    }} 

    int [][]b = new int [rows][2];
    for (int i = 0; i<numbers.length;i++){
           for (int j = 1;j>i && j<numbers.length;j++){
                   if(numbers[i]+numbers[j] == x){
                        b[a][0] = i;
                        b[a][1] = j;
                        a++;
                    }
    }
    }return b; 
    }

You need to return all possible combinations, so you need a method that returns a multidimensional array. Ok let's start with the main method; we will create a sample array with the list and then the 2D array that calls the method:

    public static void main(String[] args) {
      int a[] = {1,2,3,4,5,6,7},b[][] = Puzzle(a, 10);

      // display results:
      for(int i = 0; i < b.length; i++){
      for(int j = 0; j < b[i].length; j++){
        System.out.print(b[i][j]+" ");}
    System.out.println();}
    }    

The puzzle method; since we don't know how many rows are going to be in the 2D array i'm going to use the same loop(of checking out the combinations) to determine the number of rows:

public static int[][] Puzzle(int[] numbers, int x) {
    //Check rows number:
    int rows = 0,a = 0;
    for (int i = 0; i<numbers.length;i++){
           for (int j = i; j<numbers.length;j++){
               if (numbers[i] +numbers[j]==x){
                   rows++;
               }
    }} 

    //Check for combinations:
    int [][]b = new int [rows][2];
    for (int i = 0; i<numbers.length;i++){
           for (int j = i; j<numbers.length;j++){
               if (numbers[i] +numbers[j]==x){
                b[a][0] = numbers[i];
                b[a][1] = numbers[j];
                a++;
    }} 
    }return b; 

Good Luck.

Yes, you can improve it:

int [][] arrayOfSets = new int[5][5];

and that's it, an array of type int will have a 0 in each cell by default.

What did you write in the cmd?

Since your printer is on a network and inaccessible through ports you are left with one option, you should target the ip address of that printer so don't use a serialport because you can't assign a printer's ip as a portname.
I highly recommend you to read the link cgeier gave, your answer is there.
gd luck.

Ok so you are assuming it's COM9, to be sure add this code and tell me what happens

dim List As New ListBox
List.items.addRange(IO.Ports.SerialPort.GetPortNames)
for each item In List.Items
msgBox(item)
next

• Ok Change line 21 to

  double fixedSalary = 100000;

Reason: Type of variable not declared also a syntax error, you can't add any character such as "," in type int, double or float and it's unnecessary.

• line 23

  double commission;

Reason: since it's a fraction number (2.5) you should use type double or float

• delete line 25,26 and 27
  Reason: logic + syntax error, if you notice you repeating the same code twice so delete the above code because you didn't declared its variables

• line 36

  commissionCalc = totalSales * (commission/10);

Reason: logic error, you didn't use the commission, it's a waste of memory, so make use of it.

• lines 38 and 39

  System.out.println("The total sales of the salesperson is $"
  + commissionCalc + " using a 2.5% commission.");

Reason: syntax error, missing quote.

• in line 42 change commisionCalc to commissionCalc and totalFixedSum to totalfixedsum also in line 44
  Reason: Java is case sensitive, you should match what you wrote at first.

and that's it you are good to go.

Btw what is your portname in runtime? (msgbox(portname))

Are you sure it's connected through "COM9"? (devices and printers >> printer properties >> ports), if yes then add this code before opening the serial port

PrinterSerial.DtrEnable = True
PrinterSerial.RtsEnable = True

Here's Some of my habits that i picked up over the years, How about you?
- Refresh every 5min
- my fingers are on "A", "W" and "D" keys
- bite my nails while coding
- i had a fan problem once, and after fixing it i kept my habit of checking the task manager every now and then.

I have a beard (you can see it in my profile pic), for about 8 years.. i'm 26 now and i don't consider myself as a hairy guy, i mean i can barely see the hair on my chest and for that i can't get my beard to grow big and thick (and fine looking) like some of the members here, also here's the problem i can't shave it completely because i would look like a 16 yo kid :( i guess this is what a baby-face adults suffer from (like myself).
cheers

@Mr.M Ok the full code is in the attached text file. what i did is that i added the above code(randomize) to line 207.
but i have to warn you, i gets pretty hard on level 2 :D

Line 302 has: control.text = String.Concat("Level ", levelNum.ToString, " Lives ", lives.ToString, " Money: ", rewards.ToString) This would do the same thing in a shorter format: control.text = String.Format("Level {0} Lives {1} Money: {2}", levelNum, lives, rewards)

Yes you are right, and there's a lot of other ways to do it, but as long as it doesn't affect the performance or say the memory then there's no need to change it.

@ Mr.M

I have a suggestion...

This is a very simple code, i didn't use the math class or physics or any engine. As for your suggestion, i like the idea, you can add a level in the levels method and call it later, read through the code and you can figure it out easily (i know it a lot to read :D), but here's a sample on changing the position randomly on level 2 try it
add this to Private Sub Timer_Tick(ByVal sender As Object, ByVal e As EventArgs)

        If levelNum = 2 Then
            Dim Rand = New Random()
            Dim Pos = Rand.Next(-50, 51)
            Dim Smiley = Rand.Next(i + 1)
            If Not IsNothing(Me.Controls("enemy" + Smiley.ToString)) Then
                If Not Me.Controls("enemy" + Smiley.ToString).Location.X + Pos > 250 Then
                    If Not Me.Controls("enemy" + Smiley.ToString).Location.X + Pos < 20 Then
                        Me.Controls("enemy" + Smiley.ToString).Location = New Point(Me.Controls("enemy" + Smiley.ToString).Location.X + Pos, Me.Controls("enemy" + Smiley.ToString).Location.Y)
                        Me.Controls("blood" + Smiley.ToString).Location = New Point(Me.Controls("blood" + Smiley.ToString).Location.X + Pos, Me.Controls("blood" + Smiley.ToString).Location.Y)
                    End If
                End If
            End If

        End If

Try the publish way, because in this way you can add everything your program needs to operate to the installer, in these 2 buttons

Just to be clear, did you go through these steps?
your project properties >> publish >> installer path >> publish now >> run setup.

Check your Active solution platform if it is compatible with your System type (e.g. 64-bit)

Thanks

Hi guys, i was told that with the right settings of Qos in my router, i can prioritize the internet speed between online gaming or watching videos or browsing etc.. but what i want is to give a high priority to my pc among other pc's connected to my router.
So what do i fill in the blanks?

Thanks.

Please post the new code.

Create your database >> connect your device >> open serialport >> read data >> store data.
usually there's a manual accompanied with this device and i'm sure there's developer section in it, check it.

Replace

while (end = false)

With

while (end == false)

Or

while (!end)

Your "errors" are both logical errors and syntax errors
Syntax errors:
-when you write a method, you can't use the semicolon, just open the curly braces then write your code then close it.
-in your main method it's a "String" instead of "Strings"
-as JamesCherrill said, indent your code, so you can read it properly and faster.
Logic error:
-Since your variables are declared in a way that all your class methods can access it, you don't need to pass the variable when you call your method.
this would be enough for you worldCine();

Now consider my notes then rewrite your code and post it here so that i or other members can help you more.

Thank you for your notes.

As a game concept:
i didn't work that much on that part but still everything is editable
(variables, level etc..) and yes you are right i should remove the
upgrade button when the second round starts :D.

As for the bug
now let's talk coding, the upgrade button should be clicked once
(money issue resolved) and then disposed by the clear methode

 Private Sub clear(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs)
For XX = 0 To 10
On Error Resume Next
Me.Controls("BtnNote").Dispose()
Next
End Sub

yet for some reason i cant dispose this button as easily, that's why i
put a loop on the dispose part because at the first couple times it
will throw this error "object is not set to an instance of a object"
(i handled it by on error resume next) it's like the control "BtnNote"
never existed! But eventually it'll get disposed(according to my run
test), but not according to you..so damn :p i thought i did handle
this bug :D.
again thanks for your notes.

Use Form.ActiveForm

'close button
Form.ActiveForm.Close()
'maximize button
Form.ActiveForm.WindowState = FormWindowState.Maximized
'minimize button
Form.ActiveForm.WindowState = FormWindowState.Minimized

Here's a simple game code, open a new vb project and copy paste this code and hit run.
the game contains 3 levels, all you have to do is to shoot the smiley faces to earn money using mouse clicks, also there's a boss enemy on level 3.
I didn't have much time to add more levels to the game (actually i only tried to play it once :p), here's my point of this code "Just for fun" try to import some enemy characters(in a picturebox) and add more levels and add some sound effects to the shooting or when the enemies get hurt or whatever you would like to do.

Create a fullscreen black form with low opacity and make it on top most then display your dialog above it.

Use this code twice

My.Computer.Audio.Play(audio path, AudioPlayMode.WaitToComplete)

Try to put this code in between

System.Threading.Thread.Sleep(Time)

If e.RowIndex.ToString > -1 Then
Diameter = DesignationsDataGridView.Rows(e.RowIndex).Cells(0).Value
endif

what are you trying to do? explain more.

when you use the getdata methode it collect the values in your query, your "fuel/litre" is no longer there. instead use this code to get your item

        Dim qry As OleDb.OleDbCommand
        Dim dr As OleDb.OleDbDataReader
        qry = New OleDbCommand("SELECT * FROM [fuel_allowance] WHERE [project number]='" & projcode & "' AND [employee number]='" & empcode & "'" & _
            "AND MONTH([current month])=" & currentdate.Month & " AND YEAR([current month])=" & currentdate.Year & "", YourConnection)
        dr = qry.ExecuteReader
        If dr.Read Then
            TextBox32.Text = dr("fuel/litre")
        End If

Ok try this

Public Class Form1
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        SerialPort1.BaudRate = 19200
        SerialPort1.Parity = IO.Ports.Parity.None

End Class

You need to create the installer (go to your project properties then go to publish - publish wizard) then on the user machine double click on the installer. also make sure to set your application platform on X86 for it to work on both machines (32bit and 6bit), for that go to build - configuration manager - platform - new - new platform: X86 - ok - close.
good luck.

hmm..your code seems legit, but you didn't tell what's the error vb gives you and at what line

Yesit does. where is your dataReceived(reading) code? please post it here
