| | Re: read file Hello. Both ArrayList and List classes are provided to work with dynamic arrays. But, in ArrayList all elements have type of System.Object. And in List you specify the type of elements by yourself. Let's see what it gives to you: 1. Suppose, you have an array of strings. For ArrayList: …  |
| | Hello, DeOiD. Here's one more way to go .. If choose between Array, ArrayList or List<T> - I would suggest you use List<T>. For keeping such values you can define a class or structure.

| | Hello, tiwas. Split method has a few overloads. Take a look: [url=http://msdn.microsoft.com/en-us/library/system.string.split.aspx]String.Split Method [/url] Instead of using ArrayList I would suggest you look at List<T>. It has a constructor, that can take a IEnumerable<T> as parameter, which is (in your case) the data, which Split method returns.  |

| | Hi. Well, at first - you don't change the "index" variable from the time, when it was created. You should specify the current index (since you're displaying not the first record of your array). The second one - when your prog catch the proper event to process - you're changing … |

| | Hello. You seem a bit enmeshed with variable names and Cotrol names. E.g. let's take a look at TextBox creation: [code=c#] TextBox textBox6 = new TextBox(); textBox6.Location = new Point(260, 120); textBox6.Size = new Size(42, 20); this.Controls.Add(textBox6); [/code] you have a variable named [icode]textBox6[/icode], which keeps your newly created TextBox. … |
| | Using "array[number]" you're refer to 1 single element in [icode]array[/icode], which has a position [B]number-1[B] (since the array indexes are starting from 0). If you need to pass whole array - pass just the [icode]bookArray[/icode]. |

| | Hey, akulkarni. There're some logic errors: 1. [code=java]for(j=5;j>0;j--) { i=0; while(i<5) { int c=arr[i][j]+arr[i][j-1]; System.out.print(c); i++; } System.out.println(); }[/code] Just look what happening e.g. on the first step of your for-cycle: 1. j=5; i=0; you're taking elements with coordinates (row=0; column=5) and (row=0; column=4) .. and returning sum of them … |
