Undetected Unsupported Features

Appeon Unsupported Features Analysis is capable of highlighting the majority of unsupported features contained in the PowerBuilder application. There are still a small number of features that the Unsupported Features Analysis will not detect, so they will not be listed in the UFA Report.

An application containing unsupported features can still be converted to the Web or to the Mobile and may work correctly, depending on the type and number of unsupported features. If the deployed application does not work correctly and the UFA Report does not indicate any unsupported features that are likely to cause such problems, the problems may be caused by unsupported features that have 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.

Table 23. Undetected features

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

Unsupported special 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 Appeon 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

The following two syntax:
1. UPDATE TableName SetStatement WHERE CURRENT OF CursorName;
2. DELETE FROM TableName WHERE CURRENT OF CursorName.

DataWindow expression function

lastpos	lastposw	mode	pageAcross
pageCountAcross	profileint	profilestring	stdev
var	varp

Partially supported features

Some partially supported features, for example, reading Object.DataWindow.CrossTab.Rows is supported by Appeon, 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
