How to Display Current Control Properties at Run Time (131622)

SUMMARY

While the property sheet is available for controls during design time, Visual FoxPro does not provide a direct way to display the current values of an active control during run time. You can place a maximum of sixteen entries in the Debug Window, but this has limited application.

Insert the code listed in this article in an appropriate method to display a list of the current properties and their values in a scrollable window.

MORE INFORMATION

For the following code sample to function as intended, the following conditions must be true:

The WindowState must be normal (0).
The form and control must be active and visible.
No other instances of the form can be running.

Insert the following code sample into a method (such as Click or InteractiveChange) that can be called interactively to determine the current state of the control's properties.

When you run the code, the currently active form is minimized and the property list window activated. Once the desired status is determined, close the property list window to return the form to its normal state.

Code Sample

lnCnt=AMEMBERS(paTmp,THIS)    && Store properties in private array Tmp
