The WinCreateStdWindow function creates a standard frame window.
 
Parameter       Description
────────────────────────────────────────────────────────────────────────────
 
hwndParent      Identifies the parent window. A main window is created if
                this parameter is HWND_DESKTOP or a window handle returned
                by the WinQueryDesktopWindow function. An object window is
                created if this parameter is HWND_OBJECT or a window handle
                returned by the WinQueryObjectWindow function.
 
flStyle         Specifies the frame-window style. It can be any combination
                of the WS_ styles (see Window styles) and the FS_ styles
                (see Frame styles).
 
pflCreateFlags  Specifies options that control how the frame window is
                created. If no options are specified, FCF_STANDARD is used.
                For a list of possible flags that may be used with this
                parameter, see the Frame control flags topic.
 
pszClientClass  Points to the client-window class name. If the
                pszClientClass parameter is not a zero-length string, a
                client window of style flClientStyle and class
                pszClientClass is created. This parameter is an
                application-specified name (defined by the WinRegisterClass
                function), the name of a preregistered WC class, or a WC
                constant. If this parameter is NULL, no client area is
                created.
 
pszTitle        Points to the title-bar text. This parameter is ignored if
                FCF_TITLEBAR is not specified in the pflCreateFlags
                parameter.
 
flClientStyle   Specifies the client-window style. For a list of styles that
                can be used for this parameter, see the Window styles
                topic.
 
                This parameter is ignored if the pszClientClass parameter is
                a zero-length string.
 
hmod            Identifies the module that contains the resource
                definitions. This parameter can be either the module handle
                returned by the DosLoadModule function or NULL for the
                application's module. This parameter is ignored unless
                FS_ICON, FS_ACCELTABLE, or FS_MENU is specified in the
                flStyle parameter.
 
idResources     Identifies the frame-window identifier and the identifier
                within the resource definition of the required resource. The
                application must ensure that all resources related to one
                frame window have the same identifier value.
 
phwndClient     Points to the variable that receives the client-window
                handle. It will be NULL if the function fails.
 
Return Value
 
The return value is the handle of the frame window, or it is NULL if an
error occurs.
 
Comments
 
The client window created by WinCreateStdWindow does not have an owner. If
the client window must have an owner (for example, if the client window is a
list box), the application must call the WinSetOwner function to set the
owner of the client window after the call to WinCreateStdWindow.
 
Example
 
This example shows a typical initialization function for a window. The
function first registers the window class, then calls WinCreateStdWindow to
create a standard window and returns immediately if the function fails.
Otherwise, it continues on to do other initialization processing.
 
Note that the FCF_STANDARD constant can be used only if you have defined all
the resources. For example, if you use this constant and you don't have an
accelerator table, the function will fail.
