2. Known IssuesThis section lists known issues in this release of Visual FoxPro.

2.1. Documentation IssuesThis section lists known documentation (Help file) issues in this release of Visual FoxPro.

The Toolbox Help topic indicates that you can right-click the title bar to turn docking on or off. This is onlythe case if Always on Top is turned off. If Always on Top is turned on, docking is not enabled. You canchange this setting from the context menu.

The Help file omits documentation for Error 2115 (Execution of function or command is not allowed incontext of SQL command). This error can occur if you have a UDF which attempts to close a table involvedin SQL statement containing the UDF.

The BINDEVENT() Help topic indicates that the cDelegate method must return an integer. This is onlytrue for BINDEVENT() calls using Windows Message style event handling (new to Visual FoxPro 9.0). ForWindows Messages, user code is executed instead of the default Visual FoxPro handling. The integerreturned by cDelegate is then passed on to the Windows operating system. If you want to have VisualFoxPro perform the default processing, you must call CallWindowProc, and your code can then takeaction with the returned value including passing it to the Windows OS.

Many topics in the Help file contain a horizontal scrollbar at the bottom of the content pane. This scrollbaris due to incorrect formatting and width calculation of certain tables.

The OS() Help topic includes wrong description for Product Suite bit flags value of 256. The descriptionshould be Single user (instance) Terminal Services (Remote Desktop capability for administration tasks).

The Type() Help topic indicates that a Blob data type will return a value of Q. This is incorrect. A value ofW is actually returned.

2.2. Feature IssuesThis section describes the most recent information about features included in this release of Visual FoxPro.

The PADR(), PADC() and PADL() functions use a space as default for padding to specified length. ForVisual FoxPro 9.0, you can use these functions with Varbinary data. Often, it is preferable to pad Varbinarydata with CHR(0). You can do this using the optional cPadCharacter parameter.

The Watch Window does not display the correct data type for Blob or Varchar fields when a field referencefor one of these types is added.

Query Designer will prompt with a temporary file name if you create a new query (CREATE QUERY) and tryto close the designer without first saving the file. If you select Yes, you will properly be prompted withexpected query name in the Save As dialog box.

Pageframe TabOrientation settings other than 0 (Top) are not supported on bidirectional platforms whenthe RightToLeft property is set to True (.T.).

The Visual FoxPro setup indicates at one point during the installation process that it is installing the HTMLHelp Workshop. This is an erroneous setup message. This feature is not included with this version of VisualFoxPro.
