OLEVIEW Sample: ActiveX Object Viewer

The OLEVIEW sample illustrates how to implement ActiveX Object viewers through custom ActiveX interfaces. These custom interfaces are implemented in Iviewers.dll.

NoteNote:

Some samples, such as this one, have not been modified to reflect the changes in the Visual C++ wizards, libraries, and compiler, but still demonstrate how to complete your desired task.

Security noteSecurity Note:

This sample code is provided to illustrate a concept and should not be used in applications or Web sites, as it may not illustrate the safest coding practices. Microsoft assumes no liability for incidental or consequential damages should the sample code be used for purposes other than as intended.

To get samples and instructions for installing them:

  • On the Visual Studio Help menu, click Samples.

    For more information, see Visual Studio Samples.

  • The most recent version and complete list of samples is available online from the Visual Studio 2008 Samples page.

  • You can also locate samples on your computer's hard disk. By default, samples and a Readme file are copied into a folder under \Program Files\Visual Studio 9.0\Samples\. For Express editions of Visual Studio, all samples are located online.

To build and run the OLEVIEW sample

  1. Open the solution oleview.sln.

  2. On the Build menu, click Build.

The application has an SDI interface with two panes. The left pane allows you to browse the registry by means of a tree control. Once you select a node, the right pane will display the pertinent information.

Note that this sample application cannot display information for all the objects, but rather only for objects that support the IViewer interface.

This sample demonstrates the following keywords:

AfxGetInstanceHandle; AfxMessageBox; AfxOleInit; AfxThrowMemoryException; AfxThrowOleException; BitBlt; CBitmap::CreateBitmap; CBitmap::LoadBitmap; CBrush::CreateSolidBrush; CCmdTarget::BeginWaitCursor; CCmdTarget::EndWaitCursor; CDC::Attach; CDC::BitBlt; CDC::CreateCompatibleDC; CDC::DeleteDC; CDC::Detach; CDC::GetPixel; CDC::GetTextMetrics; CDC::SelectObject; CDialog::DoModal; CDialog::OnInitDialog; CDocument::OnCloseDocument; CDocument::OnNewDocument; CDocument::UpdateAllViews; CFileDialog::DoModal; CFileDialog::GetPathName; CFont::CreateFontIndirect; CFrameWnd::Create; CFrameWnd::GetActiveDocument; CFrameWnd::LoadFrame; CFrameWnd::OnCreateClient; CFrameWnd::SetActiveView; CGdiObject::DeleteObject; CListBox::SetCurSel; CObject::AssertValid; CObject::Dump; CRect::Height; CRect::Width; CScrollView::SetScrollSizes; CSplitterWnd::CreateStatic; CSplitterWnd::CreateView; CSplitterWnd::GetColumnInfo; CSplitterWnd::GetPane; CSplitterWnd::SetColumnInfo; CStatic::SetIcon; CString::Format; CString::GetBuffer; CString::IsEmpty; CString::LoadString; CString::ReleaseBuffer; CView::GetDocument; CView::OnDragEnter; CView::OnDragLeave; CView::OnDragOver; CView::OnDrop; CView::OnInitialUpdate; CView::OnUpdate; CWinApp::AddDocTemplate; CWinApp::ExitInstance; CWinApp::InitInstance; CWinApp::OnFileNew; CWinApp::SetRegistryKey; CWnd::DoDataExchange; CWnd::DragAcceptFiles; CWnd::GetParent; CWnd::GetSafeHwnd; CWnd::GetStyle; CWnd::GetWindowPlacement; CWnd::GetWindowRect; CWnd::OnCreate; CWnd::OnDestroy; CWnd::OnSize; CWnd::OnSysColorChange; CWnd::ScreenToClient; CWnd::SetFocus; CWnd::SetFont; CWnd::SetRedraw; CWnd::SetWindowPlacement; CWnd::SetWindowPos; CWnd::SetWindowText; CWnd::ShowWindow; ClientToScreen; CoCreateInstance; CoFreeUnusedLibraries; CoGetClassObject; CoGetMalloc; CreateSolidBrush; DeleteItem; DeleteObject; EnumFontFamilies; ExtTextOut; ExtractIcon; FormatMessage; FreeLibrary; FreeProcInstance; GetBkColor; GetClientRect; GetDC; GetDeviceCaps; GetNearestColor; GetObject; GetParent; GetProcAddress; GetProfileInt; GetProfileString; GetStockObject; GetSysColor; GetSystemMetrics; GetTextExtentPoint; GetTextMetrics; GetUserDefaultLCID; GetVersionEx; GetWindowLong; GetWindowRect; IClassFactory::CreateInstance; IMalloc::Free; IUnknown::QueryInterface; IUnknown::Release; IsWindow; LoadBitmap; LoadIcon; LoadLibrary; LoadLibraryEx; LocalFree; MAKEINTRESOURCE; MakeProcInstance; MulDiv; OffsetRect; Polygon; RGB; RectVisible; RegCloseKey; RegEnumKey; RegOpenKey; RegQueryValue; ReleaseDC; SelectObject; SetBkColor; SetTextColor; SetWindowPos; TabbedTextOut; WinExec; WinHelp; WriteProfileString; _fstrnicmp; atoi; isdigit; isspace; isxdigit; lstrcat; lstrcmpi; lstrcpy; lstrlen; max; strrchr; toupper; wsprintf
