Because that's you who says 'I'm clever', that's obvious at the first sight. I personally might be even called stupid, because programming isn't what I like most. Just have to do it. But I can assure you I'm not a stupid person at all. I can do lots of things and I'm not a snob. If you don't want to do it, don't do it. Just show off replying to other posts in the same way. Good luck!

Right now you've got two separate main() functions. How about renaming each of those to something more appropriate, and then create a new main() function that calls each of them?

Why do you keep repeating this question? If you want to draw a butterfly then I would suggest you get some books and learn about graphics programming.

Hi,
I got the process ids of the excel application instances and I need to get windows handler for that.
I tried with AccessibleObjectFromWindow function as below, but I'm getting E_FAIL in hr. Any help is appreciated. Thanks in advance.
HWND hwnd = (HWND)FindWindow(_T("XLMAIN"), NULL);
Excel::Window* pWindow = NULL;
HRESULT hr = AccessibleObjectFromWindow(hwnd, OBJID_NATIVEOM, __uuidof(Excel::Window), (void**)&pWindow);

If the excel is executed by you, you can get more info by CreateProcess() to run the excel.
or when multiple excels are running, which one you can get?
|
|
|
|

Main aim is to get the window handlers of the existing excel application instances. If there are two excel applications opened, I need to get the window handlers for those two instances. From the window handlers, I need to get excel application pointers. Hope you understood the scenario. Pls let me know if you need more clarification
|
|
|
|
|
I did something else, hope it help.
EnamWindows() can get all top level windows, in your case, excel is top one, maybe you can use the function to get more info to find excels.

What's a window handler?

I suggest you DO NOT ask your silly questions everywhere.
If you don't know what a window handle is, you still have a choice: shut up.

a process created a thread (say thread-a), if something happens in thread-a, the thread calls process, then process creates another thread thread-b.
thread-a and thread-b must be in same thread level.
how to general the thread-to-process call? PostThreadMessage() can be a choice, is there other simpler ways than PostThreadMessage()? or PosttThreadMessage() is the easist way in the case?
|

When you say a process, there is a main thread in the process.
The main thread creates thread-a.
The thread-a needs to communicate to the main thread to create the other thread.
You can do this using events.
Create an event in the main thread using CreateEvent.
The main thread can then wait for the event to be signaled using WaitForSingleObject.
The other threads can then use SetEvent to signal this event.
If your main thread is a UI thread, you will need another dedicated thread to wait for the event to become signaled so that the UI thread is not blocked.
But I believe PostThreadMessage is a better way to do this.
If your process has a window, you can also use PostMessage to the main window to achieve this.

I find 2 group of raw socket functions, one is basic kind, another one starts with WSA..., such as accept() and WSAAccept().
I am wondering that if second group (WSA...) is just implemented from basic group to offer some user-convenience, or it is rebuilt with more efficient functionalities?
in raw socket, which group is better from send-receive communication view (i.e. speed)?

The WSA functions are the Windows Socket 2 implementation, and just offer some enhanced functionality. They are all described in the MSDN documentation[^]. As far as I am aware the differences in implementation are unlikely to affect the speed.

Named IP is in english characters, such as "www.hello.abc.efg" - how to convert it to digital IP, such as "196.23.72.90"?
my usage is for raw socket, I did a test, the function inet_addr(...) can change only digital IP address, correct?
|
|
|
|
|
You're going to want to look into DNS lookups, which change human readable URLs, e.g. www.codeproject.com (what you've called a named IP, which isn't strictly correct) in to IP Adresses (what you've called digital IP).
|
|
|
|
|
you are right, named and digital IPs are defined by myself, I don't know how to call them.

The former is referred to as the host name while the latter is referred to as as IP dotted address. To get one from the other, you can use gethostbyname() and gethostbyaddr(). Both, however, have been deprecated by getnameinfo().

We can use PostMessage() to post integer to HWND if a window handle is valid, but how to post a message to a class object if without HWND?
The story looks like:
MyClass my;
void MyClass::Send()
{
post_message(100);
}
void MyClass::Receive()
{
switch(...)
{
case 100:
....
break;
}
}
how to implement the user function post_message(100)?

You have to build (or use and existing) communication path between the two objects. Do both objects exist in the same application and thread, or are these disconnected objects?
