You might want to rethink this. It is an unusual approach and will be misunderstood by users. Having the mouse cursor disappear or become unresponsive will be interpreted by many users as a program hang. Some will respond by bringing up task manager to kill your program. Others will reboot their computer to get things working again. Neither is a good thing. (Yesterday I was trying to help a user who is using some buggy, no longer supported legacy software. He would have done ;exactly this ;with no hesitation.)
Perhaps you could validate the data at some point and notify the user if it is invalid. You could even set focus back to the offending control.

I am trying to change the working directory of a MFC application after
the application execution begins.
Chdir or setcurrentdirectory doesnot work for a MFC application.
Can anyone suggest how i can do this?
|
|
|
|

SetCurrentDirectory works in MFC.
Check if your path is valid.
Also you could use GetLastError after the failure of the function.
If the path is OK then some relevant code snippet about your problem could also help us to find the problem.

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[^]

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.

Hello Friends

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.

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
