Sapera LT General I/O Demo Code Samples

The following source code was extracted from the General I/O demo program. The comments highlight

the areas that an application developer needs for embedding X-I/O module controls within the imaging

application.

Main I/O Demo code

BOOL CGioMainDlg::OnInitDialog()

{

[ . . . ]

// some declarations

UINT32 m_gioCount;

int m_ServerIndex;

int m_ResourceIndex;

// Show the Server Dialog to select the acquisition device

CGioServer dlg(this);

if (dlg.DoModal() == IDOK)

{

m_ServerIndex = dlg.GetServerIndex();

m_ServerName = dlg.GetServerName();

if ( m_ServerIndex != -1)

{

// Get the number of resources from SapManager for ResourceGio type by using

// - the server index chosen in the dialog box

// - the resource type to enquire for Gio

m_gioCount=SapManager::GetResourceCount(m_ServerIndex,SapManager::ResourceGio);

// Create all objects [see the function following]

if (!CreateObjects()) { EndDialog(TRUE); return FALSE; }

[ . . . ]

//Loop for all resources

for (UINT32 iDevice = 0; (iDevice < MAX_GIO_DEVICE) && (iDevice < m_gioCount);

iDevice++)
