CREATESTRUCT Structure

The CREATESTRUCT structure defines the initialization parameters passed to the window procedure of an application.

typedef struct tagCREATESTRUCT { 
   LPVOID lpCreateParams; 
   HANDLE hInstance; 
   HMENU hMenu; 
   HWND hwndParent; 
   int cy; 
   int cx; 
   int y; 
   int x; 
   LONG style; 
   LPCSTR lpszName; 
   LPCSTR lpszClass; 
   DWORD dwExStyle; 
} CREATESTRUCT;

lpCreateParams

Points to data to be used to create the window.

hInstance

Identifies the module-instance handle of the module that owns the new window.

hMenu

Identifies the menu to be used by the new window. If a child window, contains the integer ID.

hwndParent

Identifies the window that owns the new window. This member is NULL if the new window is a top-level window.

cy

Specifies the height of the new window.

cx

Specifies the width of the new window.

y

Specifies the y-coordinate of the upper left corner of the new window. Coordinates are relative to the parent window if the new window is a child window; otherwise coordinates are relative to the screen origin.

x

Specifies the x-coordinate of the upper left corner of the new window. Coordinates are relative to the parent window if the new window is a child window; otherwise coordinates are relative to the screen origin.

style

Specifies the new window's style.

lpszName

Points to a null-terminated string that specifies the new window's name.

lpszClass

Points to a null-terminated string that specifies the new window's Windows class name (a WNDCLASS structure; for more information, see the Windows SDK).

dwExStyle

Specifies the extended style for the new window.
