Creates a new process and its primary thread. The new process runs in the same address space of the calling process or in a separate address space.

                        BOOL CreateProcess(

                            LPCSTR lpApplicationName,

                            LPSTR lpCommandLine,

                            LPSECURITY_ATTRIBUTES lpProcessAttributes,

                            LPSECURITY_ATTRIBUTES lpThreadAttributes,

                            BOOL bInheritHandles,

                            DWORD dwCreationFlags,

                            LPVOID lpEnvironment,

                            LPCSTR lpCurrentDirectory,

                            LPSTARTUPINFO lpStartupInfo,

                            LPPROCESS_INFORMATION lpProcessInformation

                        );

`CreateWindowEx`

Creates an overlapped, pop-up, or child window. It includes extra-detailed window creation parameters.

                        HWND CreateWindowEx(

                            DWORD dwExStyle,

                            LPCTSTR lpClassName,

                            LPCTSTR lpWindowName,

                            DWORD dwStyle,

                            int x,

                            int y,

                            int nWidth,

                            int nHeight,

                            HWND hWndParent,

                            HMENU hMenu,

                            HINSTANCE hInstance,

                            LPVOID lpParam

                        );
