MORE INFORMATION

Steps to Create the ActiveX control

1. Start a new ActiveX Control project in Visual Basic. UserControl1 is created by default.
2. Add a textbox to UserControl1.
3. Copy the following code to the Code window of UserControl1:

         Option Explicit
   
         Private Sub Text1_DblClick()
            Form1.Show vbModal
         End Sub
   
   						

4. Add a form to the ActiveX control project.
5. Add a CommandButton to Form1. Copy the following code to the Code window of Form1:

         Option Explicit
   
         Private Sub Command1_Click()
            Unload Me
         End Sub
   
   						

6. Change the Project name to "TestControl" and select the File/Make TestControl.ocx menu option to create TestControl.ocx. After creating the control, save and close the project.

Steps to Create Standard EXE Project

1. Start a new Standard EXE project in Visual Basic. Form1 is created by default.
2. Add an MDI Form to the project.
3. Set the MDIChild property of Form1 to True.
4. Reference the ActiveX control you compiled in the previous section by completing the following steps:
   
   
   1. From the Project menu, click Components. The Components dialog box displays.
   2. Select the Controls Tab. Check TestControl in the list box.
   3. Click OK to close the Components dialog box.
5. Add two instances of the TestControl ActiveX control to Form1. Position the two ActiveX controls so both controls are visible on the form.
6. On the Run menu, click Start, or press the F5 key to start the program.
   
   
   1. Press the Tab key to change the focus between the two controls.
   2. Double-click the text box on one of the TestControl ActiveX controls. Form1 appears. Click the CommandButton to close the form.
   3. Set the focus to one of the TestControl ActiveX controls.
      
      RESULTS: Pressing the Tab key results in a beep and the focus does not change.

Workaround

1. Open the ActiveX control project you used to create the ActiveX control.
2. From the File menu, click Add Project to add a standard EXE project. Form1 is created by default. Set the MDIChild property of Form1 to true.
3. Close the ActiveX control project. Note than an ActiveX control is added to the toolbar.
4. Add two instances of the ActiveX control to Form1. Position the two ActiveX controls so both controls are visible on the form.
5. On the Run menu, click Start or press the F5 key to start the program.
   
   
   1. Press the Tab key to change the focus between the two controls.
   2. Double-click the text box on one of the TestControl ActiveX controls. A form is displayed. Click the CommandButton to close the form.
   3. Set the focus to one of the TestControl ActiveX controls.
   You can now tab between the text boxes of both ActiveX controls.
