One possibility:
Making desired black pixel as center of your search and then exploring the pixels around, if not found increasing in 1 your search radius and try again, when you have a hit in white, getting its coordinates and making the modul of the vector from point A to B to get the distance.
But by all means:
Starting code and reading this[^]

Hi All,
I have an application that is loading a iso file. iso file has many packages to complete the application but it takes time to open an application because everytime it load all packages. So I want to take snapshot like thing So that i can resume the application from where I left it before.
Is there any mechanism to do so?

An application may save its state in order to continue his work at next startup. Have a look at the Memento design pattern [^] (also have a look at the beautiful Memento film ).

I think just a dumb interviewer may ask such a question.

I was thinking the same thing - that is a seriously assinine question. Just what does that test? Your knowledge of damned near useless trivia?

Well, you expressed better than me my feelings.

The SendMessage call doesn't return until the target window has handled the message you've sent it.
The PostMessage call puts the message in the thread's message queue and returns immediately, before the message has been handled.

What do you mean by that exactly?
SendMessage and PostMessage can be used in MFC, but generally you'll use an MFC class's methods to hide those calls.

While SendMessage() and PostMessage() can be used within MFC code, they are not related. They are from the Windows SDK.

How COM Object gets removed from the memory?
Suppose there are 4 clients using our COM Component, One by One they goes out of scope ..At which point the component knows that it has to unload from memory.? Once the COM Object's reference count reached to zero then at this point which mechanism works to remove it from the memory.
Thanks

Do u mean the interface count?
if so then [^]

The COM object's 'Release' method would call delete this; when the reference count is zero to delete itself.

It is a responsibility of the COM object developer. When the reference count goes to zero then there are no references pending on the object (probably there aren't...: the reference count is shared mechanism of both the COM server and the client) and the object may choose to free its COM resources (as it usually do).
