I have a timer, how starts, when the text in a label appears and stop when you click on a button. Now i want to stop the reaktiontime and save it in a list, which i want to sort, so i can give out the fastest and lowest reaktiontime in a label. but in my code every time it shows 00:00:00 in the messagebox :(

In a first run i tried to alter your code so that it should run. But i found so many (coding style) issues within there that i simply wrote a completely new example. It also has some minor issues (e.g. size of buttons; it is possible that a color button occurs twice). But it hopefully shows you how TimeSpan and all the other parts can work together.

I think your problem here is that the resolution of DateTime is less than the intervals that you are trying to measure.
Instead of using DateTime, try the following:
Create a private Stopwatch field called stopwatch.
Stopwatch stopwatch = new Stopwatch();
Then change your tick handler to:
private void timMessung_Tick(object sender, EventArgs e)
{
if (timMessung.Enabled == true)
{
stopwatch.Restart();
}
else
{
ts.stopwatch.Elapsed();
}
}
However, I'm also not sure about your logic to do with when you restart the stopwatch. (Where I put stopwatch.Restart().) Do you really want to keep restarting the stopwatch at that point?
use:
ts = Time1.subtract(Time2);

I have a problem with the greyhound application that I have created. when I use the radio button to select who is placing a bet (Say Bob) and put his bet amount to 10 on dog number 4, (see image #1) when I click Bets, to update the 'Bob hasnt placed any bets' label with the description() method I get an error (see image #2)
What should happen is where it says "bob hasnt placed any bets" it should now read "bob bets 10 bucks on dog # 4. I have established this is failing due to the bettor returning NULL, but I cannot work out why this is when Bettor is referencing the Guy class which contains the bettor's name.
On a side notem when the race finishes and if Bob wins, he is note getting paid so either the PayOut() or Collect() methods are not working either.
Below are my 3 classes and my Form1.cs

{
//1. Move forward either 1,2,3 or 4 spaces at random
int moveforward = Randomizer.Next(1, 4); // declare an int called 'moveforward' will move forward 1,2,3 or 4 spaces at random
//2. Update the position of my PictureBox on the form
Point p = MyPictureBox.Location; // current location of the picture of the greyhound
p.X += moveforward;
MyPictureBox.Location = p;
//3. Return true if I won the race
if (p.X >= RacetrackLength)
return true;

in PlaceBet method you have forgotten to set the Bettor property:
if (Cash >= Amount)
{
Cash = Cash - Amount;
MyLabel = new Label();
MyBet.Amount = Amount; // HERE
MyBet.Dog = Dog; // HERE
UpdateLabels();
return true;
just add there also a line:
MyBet.Bettor = this;
Explanation/rationale: The point is that without it, when a "Guy" creates a "Bet", the Bet does not get to know who has created it. Nowhere in your code you set the Bettor field, so it never has a chance to be set to something meaningful. The bet will simply retain the default NULL value in this field. As I do not actually read/trace all the code, I think the simpliest way would be to make the Bet know his owner straight from the very beginning.
In Guy.cs when you call PlaceBet(...) and create instantiate the bet, you need to set:
this.MyBet.Bettor = this;
Within this function, this refers to the instance of Guy that is placing the bet.
The second problem you have is with the creation of a new instance of Label, without actually replacing the Label on your form with the new one. In summary fix the PlaceBet(...) method like so:
public bool PlaceBet(int Amount, int Dog)
{
this.MyBet = new Bet();
if (Cash >= Amount)
{
Cash = Cash - Amount;
// remove the following line
// MyLabel = new Label();
MyBet.Amount = Amount;
MyBet.Dog = Dog;
// insert this line...
MyBet.Bettor = this;
UpdateLabels();
return true;
}
else
{
return false;
}
}
I just performed this exercise myself in the book... been running through it. I looked over your code to see how you took care of this problem and I found a pretty big bug in how you handled paying out the betters - In form1.cs when you allow your loop to capture multiple winners you are not continuing to distribute winnings with the Collect method to anyone who bet on anything besides the last winning dog
while (num_winners == 0)
{
for (int i = 0; i < Dogs.Length; i++)
{
if (Dogs[i].Run())
{
num_winners++;
winner = i + 1;
}
}
Application.DoEvents();
System.Threading.Thread.Sleep(3);
}
if (num_winners > 1)
// you say that you have multiple winners right here but you never eval on
//it - winner is still set to one value above
MessageBox.Show("We have " + num_winners + " winners");
else
MessageBox.Show(" Dog #" + winner + "wins!");
for (int i = 0; i < Dogs.Length; i++)
{
Dogs[i].TakeStartingPosition();
}
for (int i = 0; i < Bettors.Length; i ++)
{
Bettors[i].Collect(winner);
Bettors[i].ClearBet();
Bettors[i].UpdateLabels();
}
What will need to be changed to correct this and disperse bets appropriately:
1) Make the betting scheme more realistic - when the bet is placed - subtract the money. You need to allow for a Re-Bet to take place just in case someone wants to redo one of the users on the front page
in guy.cs
public bool PlaceBet(int amount, int dog)
{
// place a new bet and store it in the bet field, return true if there is enough money
if (amount > Cash)
{
MessageBox.Show("I don't have enough money for that bet!", Name + " says...");
return false;
}
else
{
if (this.MyBet == null)
{
this.MyBet = new Bet() { Amount = amount, Bettor = this, Dog = dog };
this.Cash -= amount;
this.UpdateLabels();
return true;
}
else
{
this.Cash += this.MyBet.Amount;
this.MyBet = null;
this.MyBet = new Bet() { Amount = amount, Bettor = this, Dog = dog };
this.Cash -= amount;
this.UpdateLabels();
return true;
}
}
}
2) Now that the betters already lost/submitted their money and we don't have to worry about sending negative monies to them if their dog doesn't win, the Bet.cs Payout method can be updated to only provide a positive return if the winning dog matches their bet dog. if it doesn't, it returns nothing.
public int PayOut(int Winner)
{
// the parameter is the winner of the race. If the dog won, return the amount bet.
// otherwise return nothing
if (Winner == Dog)
{
int payout = Amount*2;
return payout;
}
else
{
int payout = 0;
return payout;
}
}
3) and now we can adjust our scheme in form1.cs to take care of paying multiples (even though this never really happens)
private void formButtonRace_Click(object sender, EventArgs e)
{
int winner = 0;
int windog = 0;
int count = 0;
for (int i = 0; i < Bettors.Length; i++)
{
if (Bettors[1].MyBet != null)
{
count++;
}
}
if (count == Bettors.Length)
{
while (winner == 0)
{
for (int i = 0; i < Dogs.Length; i++)
{
if (Dogs[i].Run())
{
winner++;
windog = i + 1;
for (int i2 = 0; i2 < Bettors.Length; i2++)
{
Bettors[i2].Collect(i + 1);
}
}
Application.DoEvents();
System.Threading.Thread.Sleep(3);
}
}
if (winner > 1)
{
MessageBox.Show("Multiple winners!", "WOW");
}
else
{
MessageBox.Show("The winner was dog #" + windog);
}
for (int i = 0; i < Bettors.Length; i++)
{
Bettors[i].ClearBet(true);
}
for (int i = 0; i < Dogs.Length; i++)
{
Dogs[i].TakeStartingPosition();
}
}
else
{
MessageBox.Show("Not all players have placed their bets!", "Wait wait!");
}
}
The reason why my ClearBet is passing in a bool is because I had to restore the money bet to each individual Guy if the reset button was pressed. However, if the race was completed I wanted to reset them without returning their bets.
This is that section for me in my code:
public void ClearBet(bool isRaceOver)
{
if (isRaceOver)
// reset bet when race is over
{
MyBet = null;
}
else
{
if (this.MyBet != null)
{
Cash += this.MyBet.Amount;
this.MyBet = null;
}
else
{
this.MyBet = null;
}
}
UpdateLabels();
}
In the PlaceBet() method, you are overwriting MyLabel with a new Label() therefore the original context of the label on the form is lost.
Although you are actually updating a Label, it's not the Label on the form.
public bool PlaceBet(int Amount, int Dog)
{
this.MyBet = new Bet();
if (Cash >= Amount)
{
Cash = Cash - Amount;
MyLabel = new Label(); // remove this
MyBet.Amount = Amount;
MyBet.Dog = Dog;
UpdateLabels();
return true;
}
else
{
return false;
}
}
I need a help on this,
There are 3 picture boxes, red should grow its Width to left, green should grow its height to top blue's width to right
also if one reaches the top border / any text boxes it should give an error / stop execution
I need to add more picture boxes in future and if two of them collides it should give an error / stop execution. I have managed to code them to go up, however unable to get other functions working. Please some one help me with this.

I have a simple Windows Forms application which is used to calculate the solutions to a quadratic equation. Since it requires some values to be inputted into three different textboxes and then upon clicking a "Calculate" button, makes some calculations with the inputted values. Upon testing the application, and clicking the "Calculate" button prior to inputting any values, I get a Input string was not in a correct format This is due to trying to parse a non-existent value. Is there any way to avoid this? I tried to construct a conditional based on if the button was clicked and there was no values in the textboxes, to not do anything, but that didn't quite work. Here is my designer code:
namespace QuadraticSolver

You can use the double.TryParse method.
This is better than checking for == "" since it will tell you that you can not parse "Hello" as a double too.
You also need to return from the event handler if one of the TryParse returns false.
You may consider using a NumericUpDown control instead. You are guaranteed the input from this control will be numeric. All the code that is required is then:
double userNumber = myNumUpDown.Value;
You can even restrict the number input to ensure it falls within your defined range
myNumUpDown.Minimum = 300;
myNumUpDown.Maximum = 500;
Along with many other things. Finally, it even comes with up/down GUI controls so your users can be super lazy and enter the number with their mouse!
You can try this format,
replace the textbox1 with your textbox name.
int a = textbox1.Text != "" ? Convert.ToInt32(textbox1.Text) : 0;
int b = textbox2.Text != "" ? Convert.ToInt32(textbox2.Text) : 0;
int total = a + b;
you can reassign the result this way:
textbox3 = total.toString();
if (txtA.Text == "" || txtB.Text == "" || txtC.Text == "")
{
string stringSol = "Please enter some values!";
txtSolution1.Text = stringSol;
txtSolution2.Text = stringSol;
return;
}
I'm trying to program in a performance counter into my C# application that launches another process and checks the processor usage of that launched process. As I understand it, the performance counter class requires me to assign a category name , a counter name, and a process name. I can get the process name easily enough, but is there a list of some sort on the internet that has all possible category and counter names I can assign? I tried scouring MSDN for something like this, but I didn't find anything.
Thanks for all the help!
I think you want to know what aspects of the process you can monitor. A list of the Process Performance Counters is available here.
Nevertheless, you can use the GetCategories static method to list all categories in the machine or you could be more specific and create the PerformanceCategory for the "Process" category and use the GetCounters to get a list of all counters available.
Hope this helps.
For those who want to quickly browse and find needed Counter here's a quick Form that displays three list boxes with |Categories|Instances|Counters| and a Counter Value that is updated on a timer. With filters.

You can assign them whatever you want. The Performance Monitor will simply show whatever category you choose and whatever counter name you choose for your particular need.
CounterCreationDataCollection ccdc = new CounterCreationDataCollection();
ccdc.Add(new CounterCreationData("Counter Title", "Counter Description", PerformanceCounterType.NumberOfItems32));
PerformanceCounterCategory.Create("My Counter Category", "Category Description", PerformanceCounterCategoryType.Unknown, ccdc);
