char a[50][50] declares a as a 50-element array of 50-element arrays of char. That means each a[i] is a 50-element array of char. It will be laid out in memory like: +—+ a: | | a[0][0] +—+ | | a[0][1] +—+ | | a[0][2] +—+ … +—+ | | a[0][49] +—+ | | a[1][0] +—+ … Read more

I see four things in your code: Don’t forget the ; at the end of your jquery click event definition. You should use #someDiv instead of .someDiv as someDiv is an Object Id, not a Object class. This was already mentioned by Wesley. You can’t use this.val() since val() is not a native javascript function. … Read more

You can use reflection to dynamically create an instance of a type, bind the type to an existing object, or get the type from an existing object and invoke its methods or access its fields and properties I have Used reflection for dynamically … Read more
I can only hazard a guess at what you are asking, but if you want the username and password to both be correct before showing the form use this instead if (tbUsername.Text == “username”) { if(tbPassword.Text == “password”) { AdminMainMenu x = new AdminMainMenu(); x.Show(); t.Play(); this.Dispose(); } else { MessageBox.Show(“Wrong password”, “Error”); } } … Read more
The ApplicationHelper.DoEvents() in dt_Tick probably does nothing, since there are no events to process. At least not the ones you’re probably expecting. If I’m not mistaken, your code will just quickly set the Radius to 0, then 1, 2, and so on in quick succession, and finally to 19. All of that will happen every … Read more
List<Book> list Here list is a reference to an object, not an object itself. When you call interface methods on this reference, you are actually calling the overridden methods of some concrete class that this reference points to. To illustrate List<Book> list = new List<Book>(); //Illegal List<Book> list = new ArrayList<Book>(); //legal ArrayList is a … Read more
The reason I can think of why this returns ERROR: if (in_array(array(‘string’, ‘id’), array(‘string’, ‘id’))) { echo ‘IN ARRAY’; } else { echo ‘ERROR!’; } is because PHP is checking each of the haystack’s values against the needle itself. Suppose you have 2 arrays like so: $a = array(‘string’, ‘id’); $b = array(‘string’, ‘id’); $a … Read more

I would guess that you can use e.g. gdk_display_put_event(), but your question is not very clear. Do you expect other applications than your own to see the emulated keyboard events? Not sure GDK can do that. solved How simulate a key event with GDK? [closed]
I think you started in the wrong way: your node structure contains pointer to a pointer. struct node { string info; struct node **next; }; that might be the reason the code does not make sense. You can use (and generally you do things this way) a simple pointer: struct node { string info; struct … Read more
Declare an array of twenty-six characters. In a loop from zero to twenty-four (inclusive) generate a random value between ‘0’ and ‘9’, and add to the array. Terminate the array with the string terminator. Now you have a string with 25 random decimal digits. For the actual random-number generation, I suggest you look into the … Read more
Assuming you want a list of dicts as the output of the json with each dict be the form in your question: The following one liner will put it into the data structure your looking for with each tuple generating it’s own complete structure: [{‘name’:i[0], ‘children’: [{‘name’: i[1], ‘value’: i[2]}]} for i in tuples] But … Read more
If you go through for you will find all the expressions are wrong – For for($x++ ; $x==2 ; $x=2) The first $x++ 0. – Incrementing an undefined variable sets it to 1, because it converts null to 0 when it’s used in an arithmetic context.. The second $x==2 will return false and the iteration … Read more
