Win32 Splitter Control - winapi

Of all the different controls that there are for Win32, is there any basic, lightweight Splitter/Splitcontainer control available (meaning one or two C/C++ files max)?
I can't seem to find any in the default controls shown in Visual Studio, and everything I find online seems to be for MFC, which I'm not using in my project...

No there is no native win32 splitter, you have to use a framework or write your own. Codeproject even has its own splitter category.
If you write your own you basically have two options:
The parent of window A and B is the splitter (The splitter border comes from WS_EX_CLIENTEDGE on windows A and B)
A and B are separated by a third window; the splitter

There's a native splitter in Win32,
it's basically just transform mouse icon to IDC_SIZENS in this example, and tracking mouse movement and then resizing the control based on mouse movement.
See here: Split Window using Win32 API

There is no native win32 splitter, I made one using pure win32 api in one cpp file.

Error creating a screenshot in the winapi service

I have a client application written in C++, and a server written in Python. This application has several functions, including getting a screenshot of the client's desktop and getting this file on the server.
When I run these programs without any add-ons, everything works. I need to upload my client to the service, and I do it through CreateProcess[client file] inside of my service. All other functions besides the screenshot work with this approach.
Server code, getting a screenshot:
if (cState == State.GETTING_SCREENSHOT):
message = "SCREENSHOT".encode('utf-8')
MySend(client_sock , message)
curr_number = 0
with open("settings.txt" , 'r') as settings:
curr_number_str = settings.readline()
curr_number = int(curr_number_str)
with open("settings.txt" , 'w') as settings:
settings.write(str(curr_number + 1))
screenshot_file = str(curr_number) + ".png"
with open(screenshot_file , 'wb') as file:
while True:
data = MyRecv(client_sock , 40000)
data_arr = bytearray(data)
if (data_arr[:10] == b'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'):
continue
if (b'ENDOFF' in data):
break
file.write(data)
cState = State.INPUT_COMMAND
Client code:

How to get windows folder display order by C + +

I need to get the pictures in the windows folder and sort them according to the order in which they are displayed. Now there is a method to traverse the entire folder display items through the handle by getting the folder window handle. However, this method has a drawback: it can't get the order of the unopened folder, because there is no open file and no window handle.
Qt is used.
Please forgive my grammatical mistakes.
//Find out the current folder window according to the mouse click position
HWND findOpenFileWindow(const QString& path)

WINAPI- WM_QUIT message not being sent

I have a callback function:
LRESULT CALLBACK MainWndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) {
if(msg == WM_DESTROY || msg == WM_CLOSE) {
std::cout << "Close or get DESTROYED!\n";
}
if(g_mApp)
return g_mApp->MsgProc(hwnd, msg, wParam, lParam);
else
return DefWindowProc(hwnd, msg, wParam, lParam);
}
However, "Close or get Destroyed" isn't printed when I click on the X button or press Alt+F4. Infact, I am unable to move the window by the mouse!
Some other functions:

!PeekMessage is wrong, if it returns non-zero you got a message you need to handle.

Developing with Firefox SDK with IDE (Visual Studio 2013 maybe)

I started developing a Firefox add-on, however I could not find any IDE specifically for Firefox. For most part it doesn't really matter because I can just open Javascript files and edit them (I use VS2013 and Web Essentials (I think)).
Up to this point everything is acceptable, but when I have to use cmd every time to run this plugin and then read console logs from cmd, it becomes a nightmare.
So my is - is there some way to launch, develop and log Firefox plugin just like any code in Visual Studio 2013? Other IDEs are welcome too.
Well I think it would be possible to create Visual Studio add-on, but it just too much work. However, I managed to partly integrate Firefox add-on creation into VS2013 with c++ code. It redirects cmd window so that means, that you'll output from cmd in "Output" window while debugging.
I'm leaving complete code with steps in case someone else needs this (C++11 is required):
Create Win32 C++ project (not cmd one).
Paste code (below) into cpp file.
Change YOUR_EXTENSION_NAME to your add-on name.
Run code once, it should throw message box with info where to put Add-on SDK.
Copy SDK files to that folder.
Run code again and exit (you may exit however you want, it should terminate remaining windows).
Now there are 3 options for file (.js, .css, etc.) linking:
Create files manually in SDK folder and add them manually to project.
Create files via VS2013 menu and then uncomment and modify, add, delete lines in do while loop.
Create files via VS2013 menu, but choose SDK folders.

How can I reinitialize my code

Hi I am currently working on a project where we are creating a UDP server to communicate with a KUKA robot. We are able to establish the connection with the robot and exchange the data back and forth but when an event occurs such as the robot faulting out due to motor over torque. So to detect this fault we have added a timeout to the code so that the main dialog box will close and reopen so that all the variables will be reinitialized and we can set the connection to reestablish.
Heres the server code:

There is more code associated with the solution that if it is need I can attach. My thougt was thought to just call the WM_INITDIALOG case so that basically it would be the same as closing the program out and re opening it. Any suggestions would be appericated.
Callign WM_INITDIALOG definitely won't do what you think it will. Don't send random Windows messages unless you understand them exactly.
My suggestion, given your design, would be to have your program launch another instance of itself and have the old instance exit. Look into CreateProcess on MSDN for the details on how to launch another process. I think that this will be the most maintainable and easy-to-code solution given what you already have.
I would suggest making repeated calls to DialogBox like this:
do
{
DialogBox(hInstance, (LPCTSTR)IDD_HAPTIC, NULL, HapticBox);
} while (ReOpenDialog);
Where ReOpenDialog is a global you set according to the success of your operation (or, to avoid a global, you could use the dialog return result from DialogBox via EndDialog).
Also, you don't need a message loop because DialogBox calls have their own one inside, thus creating a blocking call (which is why my above loop will work, in fact!).
