DOCUMENT:Q143298 08-FEB-2000 [foxpro] TITLE :How to Use Indirect Referencing of Objects Creatively PRODUCT :Microsoft FoxPro PROD/VER:WINDOWS:3.0,3.0b OPER/SYS: KEYWORDS:kbcode ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b ------------------------------------------------------------------------------- SUMMARY ======= Visual FoxPro allows indirect referencing of objects with THIS, THISFORM, THISFORMSET, and object.PARENT. With a little code, you can expand this list to include THISPAGEFRAME and THISPAGE. The example in this article will not work with the Init event of an object, however it can be used elsewhere. MORE INFORMATION ================ Step-by-Step Example -------------------- 1. Create a new form, and place a pageframe on the form. 2. Add the following code to the Page1.Activate event: ********* Begin Page1.Activate ********* PUBLIC THISPAGEFRAME, THISPAGE THISPAGEFRAME=THIS.PARENT THISPAGE=THIS ********* End Page1.Activate *********** 3. Add the following code to the Page1.Deactivate event: ********* Begin Page1.Deactivate ********* RELEASE THISPAGEFRAME, THISPAGE ********* End Page1.Deactivate 4. Repeat steps 2 and 3 for Page2 using the exact same code. 5. Add a command button to Page1, and place the following code in the Click event for the command button: *********** Begin CommandButton.Click *************** THISPAGE.Caption="Visual FoxPro" *********** End CommandButton.Click ***************** 6. Run the form. Click the command button. Note the Caption of page1 changes to Visual FoxPro. NOTE: The INIT event of the objects would not recognize THISPAGEFRAME and THISPAGE.
