This method is for internal use only.

The IStiDevice::Initialize method initializes an instance of the COM object that defines the IStiDevice interface.

Syntax

HRESULT Initialize(
  [in] HINSTANCE hinst,
  [in] LPCWSTR   pwszDeviceName,
       DWORD     dwVersion,
       DWORD     dwMode
);

Parameters

[in] hinst

Caller-supplied instance handle of the calling process. This handle is obtained by calling GetModuleName(NULL).

[in] pwszDeviceName

Caller-supplied pointer to a string representing an internal device name, obtained by calling IStillImage::GetSTILaunchInformation.

dwVersion

Caller-supplied STI version number. This value must be STI_VERSION, defined in Sti.h.

dwMode

Caller-supplied constant value indicating the Transfer Modes in which the device is to be used. The following values are valid.

Mode	Description
STI_DEVICE_CREATE_BOTH	The device is being opened for both obtaining status and transferring data.
STI_DEVICE_CREATE_DATA	The device is being opened only for data transfers.
STI_DEVICE_CREATE_STATUS	The device is being opened only for obtaining status information.

Return value

If the operation succeeds, the method returns S_OK. Otherwise, it returns one of the STIERR-prefixed error codes defined in stierr.h.

Remarks

The IStiDevice::Initialize method initializes the COM object instance that was created by calling IStillImage::CreateDevice.

Because IStiDevice::Initialize is called by IStillImage::CreateDevice, clients of the IStiDevice interface do not typically call this method directly.
