How to set the size and position of the main window that comes out at the beginning in MFC

- - The simplest design interface can be changed first.

initinstance()

function, add movewindow function m pmainwnd->showwindow(sw show) in the form display part;

m_pmainwnd->setwindowtext("...");

m_pmainwnd->movewindow(crect(60,10,950,710));

m_pmainwnd->updatewindow();//

For this you must first know:

1,You have to know that the system itself has set the display position of the window,It's when you createwindow,But you'd better not change that position,Because that's the source provided by Microsoft**,After you change that,Then all your window displays are your current settings;

2. You can only set the position of the window after it has been successfully created, just like: when something doesn't exist, you can't make any requirements for it;

3,You have to find where the window was just created successfully,Where is it displayed when it is displayed,I can tell you,It's done in the instance() function,But,This is just instantiating this application.,There's only one domodal() in this.,Basically, there's nothing to change in this.,There's also a position where the oninitdialog() function is.,It's to initialize this dialog., Naturally, the position and size of its display can be controlled, so you can call movewindow() here.

As for another function, it's setWindowPoS(), which I've just tried, and it doesn't work for applications with dialogs, which should be used when using pop-ups in single-document and multi-document applications.

Use movewindow(1,1,100,100) in oninitdialog() to display a dialog box with a width of 100 and a height of 100 in the position of (1,1).

Some programs will record the location and size of the window when it is closed, and will revert to the last position when it is opened the next time, such as the notepad that comes with Windows. But not all programs have this feature.

In the PrecreateWindow, after the todo comment section, add: &= ws thickframe; Remove resizable borders |= ws_dlgframe;Add a border that cannot be changed in size.

When you drag the window, there is an onsize message, in the function that the message responds to or the handle of the outer window, and then set the size of the outer window through the handle.
