What does your draw method and loadTextures method look like?

Unless you specifically tell openGL to render the shapes using just color, it'll render them with what ever settings were applied and in your case it looks like you're binding the texture and then leaving it bound for all shapes.

It would have to be a dynamic_cast for it to throw an exception.

Open the Error Log window and see what error was reported at the last crash.
Fredrik Bornander 19-May-15 3:07am View
   
The code looks like it should work, are you saying it's not printing "Tie Game" if the board is filled up without a winner found?

One thing you could try to change is
Array [0] == Array[otherPlayer]
You shouldn't really be comparing strings like that, use the .equals method instead.
Fredrik Bornander 18-May-15 6:45am View
   
If you have a scenario where the content view changes frequently and is heavy to create then, Yes, I would consider a different approach. But in this case I think the use-case is simpler so a straight forward approach like this is most likely Ok.
Fredrik Bornander 31-Mar-15 4:28am View
   
Probably not, in most cases you do not need to worry about this. Just re-throw using throw; and you'll be fine.

I managed to find the extract from Richter's book;
https://books.google.de/books?id=36tCAwAAQBAJ&pg=PT686&lpg=PT686&dq=Boolean+trySucceeds+%3D+false%3B&source=bl&ots=7j0BSnkwFV&sig=3ujzJWRYvpF6k-qvWiuxq2hDw6U&hl=en&sa=X&ei=QVoaVZeBPYv5atatghA&redir_esc=y#v=onepage&q=Boolean%20trySucceeds%20%3D%20false%3B&f=false

It does, but only as far as the CLR is concerned. The exceptions in the CLR (on Windows) are implemented using SEH (Structured Exception Handling), and it's that that's creating a new stack frame.
If you use it from within the CLR, it works as you thought, if you need to inspect a crash dump it works the other way.

Are you applying SAT before you do the line-line intersection checks?
Fredrik Bornander 4-Feb-15 17:21pm View
   
Sorry I was too lazy putting that together. In addition to translate the cylinder along the distance between point a and b, you also need to translate it to point a to make sure it's in the correct place.
I've fixed that for you in this project;
OrientationTest.zip (10.9 KB)

Apologies for the mistake.
Fredrik Bornander 3-Feb-15 10:45am View
   
Can't figure out where that went wrong. But lets try this instead;
OrientationTest.zip (10.8 KB). This is a WPF app that replicates what you're trying to achieve. Look at that code, all in the MainWindow essentially and see if that helps. If you set up the WPF app to have the same input in terms of where the red line start and stops you should be able step through both and figure out where your values go wrong.

Really hope we'll get it right this time :)

Can you show me a image of what the result was, maybe I can deduce what went wrong from that.

If you take a vector that is the direction of the red line, in your code x, y, z, and call it Vr, then take the vector that is the direction the cylinder extends in before being rotated to match the red line (lets say [0,1,0], or whatever your CreateCylinder call yields), call that Vc.
I think that if you then get the angle between those vectors, call it A, then you'll want to rotate the cylinder A radians around the axis that is the cross product of Vr and Vc.

Are you doing network operations on the main thread?
android.os.NetworkOnMainThreadException seems to indicate that and you can't do that. Do all your network calls on a separate thread.

It doesn't matter that much if it's a service or a "normal" activity, you listen to broadcast events the same way, more or less.

Pretty much, yeah. EF will create a proxy and it can only override the virtual properties (obviously), and to to lazy loading EF needs to intercept the call to the getter/setter and provide the lazy implementation instead of the standard property implementation.
Fredrik Bornander 21-Nov-14 4:27am View
   
Are you sure you have allowed access to the reader? I think the GetDefaultAsync will return null rather than chucking an exception on access rights issues.
Fredrik Bornander 19-Nov-14 11:02am View
   
Yes. my_array is a dynamically allocated array.
Fredrik Bornander 19-Nov-14 9:56am View
   
My code does that.
The array will be filled with the number from the second line, the my_array int-array holds as many numbers from the second line as is specified on the first line. And the count variable holds the count of numbers.

Did you give the full path to your file?
Has the file got lines that aren't numbers in it?
Fredrik Bornander 19-Nov-14 7:19am View
   
Change the for loops from
for(int i = 0; i < length; ++i)
to
for(i = 0; i < length; ++i)
and declare int i; at the top of the function where the loop is.

I updated the sample code to account for this.
Fredrik Bornander 19-Nov-14 7:17am View
   
You pass the filename in as a command line argument, if you don't want to do that just change
fopen(argv[1], "rb")
to
fopen("in.txt", "rb").

It's true that you don't need to read the entire file as you only need to read the number of lines specified in the first line, but unless the file has a lot more lines after the last number, that's not going to be an issue. Reading the file is fast.
Fredrik Bornander 7-Nov-14 8:27am View

Is it the remove call that fails? Have you tried checking the ret variable for false?
Fredrik Bornander 20-Oct-14 8:45am View
   
True. But that's not what's causing him to read the input four times instead of three.
Fredrik Bornander 17-Oct-14 8:05am View
   
No. And there's no point, just take your float value and multiply it by 100 (provided it's clamped to 0<=value<=1).

I'd expect C to give you little over the unsafe version. What you can do though is optimize the unsafe version with quick bail-outs like Bill's suggestion about length comparisons.
Fredrik Bornander 13-Oct-14 9:10am View
   
If it doesn't need to be thread-safe, you can extract the copy buffer to a static member (initialize to some size guaranteed to be longer than or equal to the length of your longest from string. And that will run about 10% faster than the version allocating copy on every call.
Fredrik Bornander 13-Oct-14 8:27am View
   
Was it faster for you?
Fredrik Bornander 13-Oct-14 8:25am View
   
True.
Actually I think it's next to impossible to optimize this without knowing more about it. The performance of a method will likely be different depending on the length of the strings and so on.
Fredrik Bornander 13-Oct-14 8:10am View
   
Because doing it another way is faster?
Fredrik Bornander 13-Oct-14 7:55am View
   
Cheers. I just ran the figures; on my box I get 70% faster going unsafe with pointers and about twice as slow going with linq. I would still probably go with the linq method you suggested unless proven beyond a doubt that this method is the biggest performance hog. Pointers will come back to bite your a** I think.
Fredrik Bornander 13-Oct-14 6:41am View
   
Yeah, a spec on what to achieve rather than just a view of OPs current implementation would have been good.
Fredrik Bornander 13-Oct-14 6:30am View
   
That won't yield the same result as his implementation, though.
IsStringMadeOf("A", "AA") will return true whereas IsCharMatch would be false for those parameters.

An uncaught exception in a thread will not hang/freeze your application, it will kill the thread and likely the application as well.

If you ask me, "current thread" is only relevant from within that thread. It makes no sense for an outside observer.
Consider a deadlock where you have two treads A and B waiting for each other, which of these is the current one?

I think you're better off looking into hang and crash dumps, and how to generate them. But that's just my $0.02.

Is your problem finding the different rectangles in the source array or is it (as you say) to "merge" them?

In the above example you've found rectangles
(0,0)-(1,1)
(3,0)-(4,0)
(4,1)-(4,1)
is there a reason as to why you picked those three over

Using a binary writer what's the difference in writing a '\n' and byte value of 10?

If you want to read line based, then you're not looking to use Postion and Seek(), I think.
Fredrik Bornander 30-Oct-13 5:31am View
   
You can't with that data format. Unless you know exactly how wide each field or group of fields are, then you can't seek to the next position.

In your case, you're using a string and that's going to take up a variable amount of space so without reading each element, there's no way of knowing.

Either re-think your data format or use sequential reads.

It's because my command implementation assumes a command that can always be invoked.
You're supposed to fire that event when the CanExecute of the command changes, but since this is always true it's irrelevant in this implementation.

Google WPF RelayCommand for a more complete implementation of ICommand.
Fredrik Bornander 29-Oct-13 5:42am View
   
I left that out deliberately, but it would like something like this;

public Command(Action action) {
this.action = action;
}

public bool CanExecute(object parameter) {

public event EventHandler CanExecuteChanged;

public void Execute(object parameter) {
action();
}

Which event are you listening to?
Fredrik Bornander 21-Oct-13 8:08am View
   
So the event completes, the magically the payload that is supposed to run on a background thread runs on the same thread?

Are you installing a custom thread scheduler to the Task factory?
Fredrik Bornander 21-Oct-13 7:14am View
   
I think it's unlikely that the library is waiting for any threads created in the event handler, that's a fairly complex and weird piece of functionality to add.

If you try something like this; what is printed to your output window:
<pre>
public void Call_Comes(object sender, EventArgs e) {
System.Diagnostics.Debug.WriteLine("Event fired from thread " + Thread.CurrentThread.ManagedThreadId);
Task.Factory.StartNew(() => HandleEvent(sender, e));
System.Diagnostics.Debug.WriteLine("Event processessing done");
}

private void HandleEvent(object sender, EventArgs e) {
System.Diagnostics.Debug.WriteLine("Handling on thread " + Thread.CurrentThread.ManagedThreadId);
Thread.Sleep(1000);
System.Diagnostics.Debug.WriteLine("Done handling on thread " + Thread.CurrentThread.ManagedThreadId);
}
</pre>

Can you destroy the current session if a user tries to log on again, so that the latest session is always the valid one?
Fredrik Bornander 4-Oct-13 2:56am View
   
Yes.
But you're going to have to provide a lot more information about your particular performance issue for anyone to be able to help you.

You need to make sure you include the .jar file containing the jdbc drivers when running you application.

Are you sure? :)
I misread it, well spotted.

I think you should set the DataContext to your DataTable and ignore the BindingSource. Why do you need the BindingSource?
Fredrik Bornander 1-Oct-13 3:16am View
   
What should change from 0?
Should the 0 become the value it "eats"?

Debug it and figure out what's null. Then make sure that isn't null.

Post a new question instead of commenting, it means more people will have visibility of it and you're likely to get help quicker.
Fredrik Bornander 23-Sep-13 10:33am View
   
You can either check if .Count == 0 or, if you import Linq (using System.Linq;) you can use Data.Any() which returns true if it is NOT empty.
Fredrik Bornander 23-Sep-13 6:24am View
   
Yes. So putting them in a library (like a DLL) is likely to be more convenient.
But it depends on the circumstances, sometimes including the sources in every project makes sense.

Dude, you need to explain it to me.
You can't answer "Yes" when I ask What do you mean send the notification?", it makes no sense.

What do you mean send the notification? Send it how?

I would if I understood what you wanted help with.

Yeah, I'm sorry to say I'm not following you at all now.

Did it work for you?

In your query A is an alias for a select hitting only table TableB, that doesn't work as that table does not have column AID. Your example query is incorrect as it is clearly only hitting TableB.
Fredrik Bornander 11-Sep-13 9:53am View
   
Your query makes no sense, alias A will not have column AID on it. What does the query for populating TableC actually look like?
Fredrik Bornander 11-Sep-13 4:55am View
   
You will need to provide more information that for us to be able to help you.

Cool, glad I could "help" :)
I realize it's not perfect but I don't think this is something you really want to do anyway.
I assuming that since you asked a fairly complex question you're aware that casting away const on your own return value means you might as well remove the const from the return type all together.

I've adorned my answer with a working example. Let me know if this helps you.

You can't just copy and paste my answer, it wont work as it's based on the fragment of code you supplied in your question. If you replace var with SqlCommand that should work, but you need to initialize your own Connection (cn).

Read the wikipedia article on SQL Injection and you'll understand why you NEVER want to concatenate a bunch of strings into your sql statement (especially if those strings are entered by a user).

You call p.Kill() or wait for the process to finish.

Could you add an image with a rectangle positioned in 3D space like you would want the text, draw it in paint or something, then I can (probably) show you how to position your camera.
Fredrik Bornander 23-Aug-13 2:41am View
   
Look-at target can be used to calculate LookDirection on the camera, and for some it's more intuitive to use instead of the LookDirection;
<pre>camera.LookDirection = myLookAtTarget - camera.Position;
</pre>

Sometimes it helps thinking about the camera having a position and a point it's looking at rather than changing the direction (which I know is the equivalent but still different).

What is the return value of the system call?
Fredrik Bornander 12-Aug-13 11:08am View
   
Cool. Note that I updated the example as the first attempt was leaking memory.

It allocates enough space for one.
Fredrik Bornander 9-Aug-13 10:11am View
   
Wouldn't the problem still be coming up with the correct rounding?
If the user specifies the float to 7 decimals and the sprintf rounds that to 5 then the result would be unexpected again
I think the problem is, as you said, the problem with representing nber as floating point typea. If there is a strict requirement that the input is float then something like thos cant be.reliable implemented. I.think.
Fredrik Bornander 9-Aug-13 9:35am View
   
I'm not sure how I would implement that?
Fredrik Bornander 9-Aug-13 9:32am View
   
You get "not valid port" because you haven't allow pack URIs.
New up an Application object and it'll register it for you.
Fredrik Bornander 9-Aug-13 9:26am View
   
I know, even the example I posted prints 6 decimals for the input given.
But if the input is a float it's going to be very difficult to work around that.
Fredrik Bornander 9-Aug-13 9:16am View
   
True, but it's his/hers first question so I think he/she deserves a little slack :)
