    <p>Normally if you have VC2005 or earlier the following will do:</p> <pre><code>// Parse command line for standard shell commands, DDE, file open CCommandLineInfo cmdInfo; ParseCommandLine(cmdInfo); m_nCmdShow = SW_HIDE; // Dispatch commands specified on the command line. Will return FALSE if // app was launched with /RegServer, /Register, /Unregserver or /Unregister. if (!ProcessShellCommand(cmdInfo)) return FALSE; // The one and only window has been initialized, so show and update it m_pMainWnd-&gt;ShowWindow( m_nCmdShow); m_pMainWnd-&gt;UpdateWindow(); </code></pre> <p>Note that m_nCmdShow should be set to SW_HIDE before <code>ProcessShallCommand</code> for the flicker not to occur.</p> <p>It looks like there might be a bug in VC2010 though. Since I have done this before it intrigued me and tried a fresh VC2010 project but it was not working. I noticed the problem was deep in the following MFC function.</p> <pre><code>BOOL CFrameWnd::LoadFrame(UINT nIDResource, DWORD dwDefaultStyle, CWnd* pParentWnd, CCreateContext* pContext) { // only do this once ASSERT_VALID_IDR(nIDResource); ASSERT(m_nIDHelp == 0 || m_nIDHelp == nIDResource); m_nIDHelp = nIDResource; // ID for help context (+HID_BASE_RESOURCE) CString strFullString; if (strFullString.LoadString(nIDResource)) AfxExtractSubString(m_strTitle, strFullString, 0); // first sub-string VERIFY(AfxDeferRegisterClass(AFX_WNDFRAMEORVIEW_REG)); // attempt to create the window LPCTSTR lpszClass = GetIconWndClass(dwDefaultStyle, nIDResource); CString strTitle = m_strTitle; if (!Create(lpszClass, strTitle, dwDefaultStyle, rectDefault, pParentWnd, ATL_MAKEINTRESOURCE(nIDResource), 0L, pContext)) { return FALSE; // will self destruct on failure normally } // save the default menu handle ASSERT(m_hWnd != NULL); m_hMenuDefault = m_dwMenuBarState == AFX_MBS_VISIBLE ? ::GetMenu(m_hWnd) : m_hMenu; // load accelerator resource LoadAccelTable(ATL_MAKEINTRESOURCE(nIDResource)); if (pContext == NULL) // send initial update SendMessageToDescendants(WM_INITIALUPDATE, 0, 0, TRUE, TRUE); return TRUE; } </code></pre> <p>m_nCmdShow is still SW_HIDE when this function executes but it changes to SW_SHOWNORMAL when <code>if (!Create(lpszClass...</code> line executes. I don't know why this happens in VC2010 project only, sounds like a bug to me.</p> <p>My sample project was SDI.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
