PRB: SearchForm from Wizstyle.vcx Displays Behind Desktop Form

• Microsoft Visual FoxPro for Windows, versions 3.0 and 3.0b

SYMPTOMS

If the Desktop property of a form is set to true (.T.) and either the txtbtns, picbtns, or verttxtbtns classes from the Wizstyle.vcx Visual Class Library are added, the SearchForm will be displayed behind that form whenever the Find button is clicked.

CAUSE

The purpose of setting the Desktop property of a form to true is to allow that form to be contained anywhere on the Windows Desktop. Therefore, the main Visual FoxPro window will be in the background behind the form.

When the Find button of the txtbtns, picbtns, or verttxtbtns class of Wizstyle.vcx is clicked, this creates an instance of the SearchForm class, also of Wizstyle.vcx. The Desktop property of SearchForm is false (.F.), indicating that it is to run within the main Visual FoxPro window. Therefore, it will be displayed behind a form with a Desktop property of true (.T.).

RESOLUTION

Either of the following resolutions can be used:

• Keep the desktop property of the created form as false (.F.).

  -or-

• Modify the SearchForm class of the Wizstyle.vcx Visual Class Library to have its Desktop property changed from false (.F.) to true (.T.). This causes the SearchForm to be displayed on top of the Desktop form.

STATUS

This behavior is by design.

MORE INFORMATION

Steps to Reproduce Behavior

NOTE: The following example is depends on the Desktop property of the SearchForm class of Wizstyle.vcx Visual Class Library being false (.F.), which should be the case unless SearchForm has been modified.

1. Create a new form, and add a table to its Data Environment.

2. Change the size of the form such that its Height property is 180 or less. This will permit a portion of the SearchForm to be visible.

3. Change the form's Desktop and AutoCenter properties to true (.T.). While the AutoCenter property does nothing toward contributing to the behavior that this article describes, it will be useful in helping to demonstrate it.

4. From the form's Data Environment, drag any or all of the table's fields to the form.

5. Use the View Classes tool of the Form Controls Toolbar, and click Add.

6. Select Wizstyle.vcx located in the Wizards subdirectory of the Visual FoxPro root directory (For example, C:\Vfp\Wizards).

7. Add the txtbtns class to the form.

8. Save, Close, and use the DO FORM command to run the form.

9. Maximize the main Visual FoxPro window to cause the SearchForm to be displayed in the same general area of the screen as the form that was just created. Click the form's Find button. You will observe that the SearchForm is displayed behind the form that was just created. If necessary, you can close the SearchForm by pressing ALT+C.
