參數

hInstance

Handle to the module that owns the new window.

hMenu

Handle to the menu to be used by the new window.

hwndParent

Handle to the parent window, if the window is a child window. If the window is owned, this member identifies the owner window. If the window is not a child or owned window, this member is NULL.

cy

Specifies the height of the new window, in pixels.

（指定新視窗的高度，以像素為單位。）

cx

Specifies the width of the new window, in pixels.

（指定新視窗的寬度，以像素為單位。）

y

Specifies the y-coordinate of the upper left corner of the new window. If the new window is a child window, coordinates are relative to the parent window. Otherwise, the coordinates are relative to the screen origin.(指定新視窗的左上角y坐標。如果新視窗是一個子視窗，坐標是相對於父視窗。否則，坐標是相對於螢幕的起源。)

x

Specifies the x-coordinate of the upper left corner of the new window. If the new window is a child window, coordinates are relative to the parent window. Otherwise, the coordinates are relative to the screen origin.(指定新視窗的左上角x坐標。如果新視窗是一個子視窗，坐標是相對於父視窗。否則，坐標是相對於螢幕的起源。)

style

Specifies the style for the new window.

(指定新視窗的風格(方式)。)

lpszName

Pointer to a null-terminated string that specifies the name of the new window.

(以零結尾的字元串，指定新視窗的名稱。)

lpszClass

Pointer to a null-terminated string that specifies the class name of the new window.

(以零結尾的字元串，指定新視窗類的名稱。)

dwExStyle

Specifies the extended style for the new window.

(指定新視窗擴展風格。)

注釋

Windows NT: You should access the data represented by the lpCreateParams member using a pointer that

has been declared using the UNALIGNED type, because the pointer may not be DWORD aligned.
