DirectXSetup

The DirectXSetup function installs one or more DirectX components.

int WINAPI DirectXSetup(
  HWND  hWnd,          
  LPSTR lpszRootPath,  
  DWORD dwFlags        
);

Parameters

hWnd

Handle of the parent window for the setup dialog boxes.

lpszRootPath

Address of a string that contains the root path of the DirectX component files. This string must specify a full path to the directory that contains the files Dsetup.dll, and Dsetup32.dll, as well as a "DirectX" (not case sensitive) directory containing redistributable files. If this value is NULL, the current working directory is used.

dwFlags

One or more flags indicating which DirectX components should be installed. A full installation (DSETUP_DIRECTX) is recommended.

DSETUP_D3D	Obsolete. DirectX 3 programs that use this flag install all DirectX components.
DSETUP_DDRAW	Obsolete. DirectX 3 programs that use this flag install all DirectX components.
DSETUP_DDRAWDRV	Not used in DirectX 7.0.
DSETUP_DINPUT	Obsolete. DirectX 3 programs that use this flag install all DirectX components.

Return Values

If this function succeeds, it returns DSETUPERR_SUCCESS, or DSETUPERR_SUCCESS_RESTART if the user must restart the system for changes to take effect.

If it fails, it returns an error value. For a list of possible return values, see Return Values.

Remarks
