Working around a puzzle slider game, using picturebox and tag properties. After the form has reshuffled the images, I set a function void IsWin()  using if statement to check the arrangement upon completion and display an output. but after arranging the scrabbled images the message box in the if statement doesn't pop up.

I will be glad if some anyone can help me identify what i am doing wrong. Thank you

I have 3 classes overriding a function of base abstract class A. The child classes are 1, 2 & 3. Child classes override function "public abstract void hello(var1, var2)".

Following is what I want to implement:
abstract class A
{
public abstract void hello(var1, var2); // This will be only for class 1 & class 2 (Existing function)
public abstract void hello(var1, var2, var3); // Want to make this available for class 3 only. (Want to add this new function)
}


** Currently the above code throws error and wants me to implement the new inherited abstract function in class 1 & 2.
