Undetected Unsupported Features

Appeon PowerServer provides an Unsupported Features Analysis tool for detecting unsupported features in a PowerBuilder application before generating files for the application. The Unsupported Features Analysis scans each object within a PowerBuilder application for unsupported features and generates a report that, when combined with the this help, provides a foundation for bringing a PowerBuilder application to specification.

The PowerServer Unsupported Features Analysis is capable of highlighting the majority of unsupported features contained in the PowerBuilder application; however, there are some features that the Unsupported Features Analysis will not detect, and thus they will not be listed in the Analysis Report. Approximately 5% of PowerBuilder features that are not supported by PowerServer may not be detected in the Unsupported Features Analysis.

An application containing unsupported features can still be converted to the Web and work correctly, depending on the type and number of unsupported features. If the Web application does not work correctly but the Unsupported Features Analysis does not indicate any unsupported features that are likely to cause such a problem, the problem may be caused by an unsupported feature that has not been detected. In this case, it is strongly recommended that you carefully read the undetected features listed below and examine your application to determine if it contains any of these features.

The following are unsupported features that are not detected during Unsupported Features Analysis.

Naming conventions

  • Duplicate object names. No two objects should have the same name in an application, whether they are of the same type or not. The Unsupported Features Analysis cannot detect whether object names are duplicated in an application.

  • More than one application object. Having more than one application object in an application is unsupported. The Unsupported Features Analysis cannot detect whether more than one application object is present.

  • Applications named as objects or controls. Application names that have the same name as PowerBuilder control/object types are not supported. The Unsupported Features Analysis cannot detect whether this unsupported issue is present in an application.

Null values

  • Unsupported operation

  • Expressions with Null values

ASCII characters

Vertical tab (~v)

Non-visual UserObject

A NonVisualObject object assigned to an autoinstantiated NVO or an autoinstantiated NVO assigned to a NonVisualObject object.

Variables and constants

  • Instance variables have identical names as global variables.

  • longlong variable

  • PUBLIC, PROTECTED, PRIVATE qualifier in the variable declaration

Forced conversion

Forced conversion between types

Window

Multiple MDI windows in an application.

Overloading, overriding functions

  • Dynamic calling for overloaded functions

  • Dynamic calling for overriding functions

Using the return value of some supported functions

The return value of the Open or OpenSheet functions

Operators

The operator '^' with embedded SQL statements.

Stored procedure

  • Stored procedures declared in the conditional statement

  • DB2 stored procedures

  • Stored procedures placed inside an Oracle package

  • Oracle stored procedures with PowerServer unsupported features

Cursor declare requirement

  • Cursor declared in the conditional statement;

  • If a cursor is declared for retrieving rows from table X, the table X (insert, delete, update) is modified during the cursor declare-close period.

Cursor statements

  • UPDATE TableName SetStatement WHERE CURRENT OF CursorName;

  • DELETE FROM TableName WHERE CURRENT OF CursorName.

Partially supported features

Some partially supported features, for example, reading Object.DataWindow.CrossTab.Rows is supported by PowerServer, but writing is not, therefore, using DataWindow Modify function or equivalent to write this property cannot be detected by UFA.

User interface interactions

Unsupported features in the UI such as shortcut key.

Enumerated data type

Default values of enumerate type variable

Data source

The data sources of dynamically created DataWindows are stored procedures with input parameters.

Dynamic calls

  • Dynamically call the method of a menu object.

  • Dynamically call the method that contains reference arguments.

Others

  • PBX

  • PSR, for example: dw.dataobject='*.psr'

  • Unsupported DBParm parameters

  • Encoding parameter of the Blob functions

  • filename & importtype arguments of ImportFile, ImportString, & ImportClipboard (filename can only be a text file (TXT))

  • Property defined in the string variable

  • Structure member has comment property
