CMNCTRL1 Sample: Demonstrates Common Control MFC Classes, Part 1

The CMNCTRL1 sample illustrates how to use the following common control MFC classes: CTreeCtrl, CToolBarCtrl, CAnimateCtrl, CDateTimeCtrl, and CMonthCalCtrl. It shows how the controls are created and how to change the controls using many of the different available styles. Some controls cover topics that often yield questions from the user; for example, the drag and drop implementation for CTreeCtrl.

CMNCTRL1 is the result of replacing the original CMNCTRLS sample with two smaller projects: CMNCTRL1 (tree, toolbar, date and time picker, month calendar, and animate controls) and CMNCTRL2 (progress, up/down, and slider controls). This was done to reduce the footprint of the sample code, making it easier to trace specific portions of the application.

Security noteSecurity Note

This sample code is intended to illustrate a concept, and it shows only the code that is relevant to that concept. It may not meet the security requirements for a specific environment, and it should not be used exactly as shown. We recommend that you add security and error-handling code to make your projects more secure and robust. Microsoft provides this sample code "AS IS" with no warranties.

To get samples and instructions for installing them:

To access samples from Visual Studio

  • On the Help menu, click Samples.

    By default, these samples are installed in drive:\Program Files\Microsoft Visual Studio 10.0\Samples\.

  • For the most recent version of this sample and a list of other samples, see Visual Studio Samples on the MSDN Web site.

To build and run the CMNCTRL1 sample

  1. Open the solution cmnctrl1.sln.

  2. On the Build menu, click Build.

  3. On the Debug menu, click Start Without Debugging.

When you run CMNCTRL1, select the tab for the control you want to activate. Select the styles and views from the check boxes, radio buttons, and combo boxes available in the different property pages. Note how each option changes the behavior or appearance of the control being displayed. For CTreeCtrl, you will be able to see the different notification messages sent by the control as you experiment with it.

NoteNote

Because of a display bug in the Win32 API, the tree view control will not update the node labels when the TVS_HASLINES and TVS_LINESATROOT styles are dynamically applied. To restore the labels, open and close one of the child nodes.

This sample demonstrates the following keywords:

CBitmap::LoadBitmap; CEdit::Clear; CEdit::GetLineCount; CEdit::LineIndex; CEdit::LineLength; CEdit::ReplaceSel; CEdit::SetSel; CFileDialog::GetPathName; CGdiObject::DeleteObject; CImageList::DragShowNolock; CString::GetBufferSetLength; CString::GetLength; CString::Left; CString::LoadString; CString::ReleaseBuffer; CTreeCtrl::SelectDropTarget; CWnd::GetInvalidateRect; CWnd::GetClientRect; CWnd::GetWindowRect; CWnd::SetWindowPos; CWnd::SetWindowText; DeleteItem; GetCursorPos; GetDlgItem; GetParent; GetWindowLong; InvalidateRect; CWinApp::LoadIcon; MAKELONG; MessageBeep; ReleaseCapture; ScreenToClient; SetCapture; SetWindowLong; SetWindowPos; UpdateWindow; CWnd::WindowProc; mbstowcs; rand; srand; time; wsprintf

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.
