TSTCON Sample: ActiveX Control Test Container

Visual Studio 2008

The TSTCON sample implements an ActiveX control container using MFC support for OLE embedding. You can use TSTCON to test ActiveX controls, change their properties, and invoke their methods. You can write scripts using the VBScript language to automate the testing of the controls. TSTCON can keep a log of the events and property change notifications fired by a control.


This sample requires the Microsoft Calendar Control, which is installed with Microsoft Access.

TSTCON also demonstrates several MFC programming topics, including the following topics:

  • CCheckListBox: A list box with a check box next for each item.

  • CDragListBox: A list box in which you can drag the items to rearrange their order.

  • Implementing an Active Scripting Engine host (VBScript).

  • Implementing context-sensitive help for dialog boxes.

To build and run the TSTCON sample

  1. Open the solution tstcon.sln.

  2. In the Property Pages for the TCProps project, expand the Configuration Properties node; then expand the Linker node. Under Manifest File, change the Enable User Account Control (UAC) option to No.

  3. On the Build menu, click Build Solution.

  4. Run the test container application as a stand-alone application so it can register itself with the system.

To launch a control in the container

  1. In ActiveX Control Test Container, from the Edit menu, click Insert NewControl.

  2. In the Insert New Control dialog box, from the list box, select CalendarControl, and click OK.

    The Microsoft Calendar Control appears in the upper half of the splitter window. Note that this control is installed with Microsoft Access.

  3. Manipulate the calendar by changing month, year, and date. In the lower pane, observe how the logs, events, and property change notifications are fired by the control as you manipulate it.

To change the control's properties

  1. Select the calendar control by clicking the calendar's border.

  2. From the Edit menu, click Properties. Test Container displays the Properties dialog box for the control.

  3. Using this dialog box, you can edit the properties of the control. Change the control's properties and observe the changes.

  4. Close the Properties dialog box.

To invoke methods on the control

  1. From the Control menu, click Invoke Methods. The Invoke Method dialog box appears.

  2. In the Method Name combo box, select BackColor (PropPut).

  3. From theParameter Type combo box, select VT_COLOR.
