DOCUMENT:Q161185 11-DEC-1999 [foxpro] TITLE :FIX: Report Calling Custom Method Returns Incorrect Info PRODUCT :Microsoft FoxPro PROD/VER:WINDOWS:5.0 OPER/SYS: KEYWORDS:kbprogramming kbvfp kbvfp500aFIX kbvfp500bugkbbuglist kbfixlist ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual FoxPro for Windows, version 5.0 ------------------------------------------------------------------------------- SYMPTOMS ======== A report that calls a function defined in a custom class prints the information incorrectly. However, in preview mode, values from the custom class appear correctly. RESOLUTION ========== Place the Date() function directly in the Expression box of the text box or use a user-defined function (UDF) to return the desired value. STATUS ====== Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem has been fixed in Visual FoxPro 5.0a. MORE INFORMATION ================ The example below defines a custom class that returns a character string and the system date. If the report is previewed, the date appears correctly. Printing the report, however, causes the date value to appear as a logical value (.T.). The behavior does not occur in Visual FoxPro 3.0b. Steps to Reproduce Behavior --------------------------- 1. Create a report called Ztest.frx. Place the Customer table from the Testdata database, located in the \Vfp5\Samples\Data\ folder, in the DataEnvironment. 2. Place two text boxes in the report. In the Expression box of the first text box, type "oTest.cUser" (without the quotation marks). In the Expression box of the second text box, type "oTest.dToday()" (without the quotation marks). Close and save the report. 3. Create a program containing the following code: oTest = CREATEOBJECT("Test") ? oTest.cUser ? oTest.dToday() * REPORT FORM ztest RECORD 3 TO PRINTER REPORT FORM ztest PREVIEW DEFINE CLASS test AS CUSTOM cUser = "Testing" FUNCTION dToday RETURN DATE() ENDFUNCTION ENDDEFINE 4. Run the program and note that the date appears correctly. Close the Preview window. 5. Open the program and remove the asterisk (*) from the first REPORT FORM command, and place and asterisk in front of the second REPORT FORM command. The asterisk character comments out individual lines of code. 6. Run the program and note that the printed report displays ".T." where the date should be. NOTE: Printing the report from the Preview Toolbar in Step 4 also illustrates the problem.
