By driven, we mean that any client program capable of OLE automation may create an instance of that type and read or write properties or invoke its methods. Disconnect end if destroy PBObject. In both cases above, the script attempts to create an instance of the object and, if successful, sets an attribute and then calls a function. A more ocnnecttonewobject service is also available for driving PowerBuilder objects. Application you can connect an automation client program to a PowerBuilder run-time.

After setting the LibraryList property, pwoerbuilder can create instances of non-visual objects with the CreateObject method.

CreateObject takes a PowerBuilder class name as a string. While this approach is more complex to use, it provides connecttonewobjecg flexibility at run time and does not require that the translation information described previously be recorded in the registry. In effect, the classes may be private and need not be made available to other OLE clients. This property contains the library list to be searched for plwerbuilder when creating object instances. The list must be assigned prior to the creation of the first object.

This property defaults to TRUE. As with the LibraryList attribute, this attribute is ignored once the first object instance is created. All subsequent object instances must be of the same type pCode or machine code. CreateObject accepts a PowerBuilder class name and attempts to create an instance of that class. PowerBuilder will search the library list set prior to the creation of the first object instance.

GenerateGUID creates a new Globally Unique Identifier and returns the string representation of that identifier connecttonedobject a reference parameter. This identifier should then be passed on to GenerateReg. Unable to generate GUID. GenerateRegFile creates a file with registry update instructions for deploying an object as an OLE Automation server object. The Powerbhilder and MachineCode attributes must be set to the desired values before making this call.

To create and install a PowerBuilder non-visual object for use by OLE Automation clients, you must complete the following steps:.

CreateJsonArray – – PowerScript Reference

Assuming powwrbuilder first three steps are understood, the remaining question is how to create the registry file connectonewobject merge it. Application exposes two methods which can be used to create the appropriate unique identifier GUID – Globally Unique Identifier and then to create a registry file that can be used to update the registry on the client machine.

See Appendix B for a sample of the registration file produced by this script. Two new files need to be included in the both PowerBuilder development environment installation and the run-time deployment installation.

TLB must be updated to reflect the installed directory.

ConnectToNewObject returns -3

TLB need only be installed for run-times which need access to PowerBuilder. This could be made optional. For each Non-Visual object deployed, a powerbbuilder generated registry file. REG file must be installed.

Presumably the companion product PBSetup will offer this capability. For objects accessed through programmatic identifiers in the registry, the registry entry indicates the binary type of the object pCode or machine code. Application defaults to a machine code implementation. Each object created through a programmatic identifier gets its own run-time session. These objects may be passed to each other as parameters but will not be recognizable to each other as PowerBuilder objects but only as OLE automation objects.

As a result, mixing the two types is perfectly acceptable since they will interact only as OLE automation objects. You cannot create both a pCode and a machine code object from the same object instance of PowerBuilder. If you create more than one PowerBuilder. Application object instance, they may be used to create instances of different types pCode or machine code. A Visual Basic programmer may do just this using the syntax below: Disconnect end if destroy PBObject In both cases above, the script attempts to create an instance of the object and, if successful, sets an attribute and then calls a function.

Application A more advanced service is also available for driving PowerBuilder objects. A Visual Basic programmer may do this using the syntax below: Application string LibraryList This property contains the library list to be searched for classes when creating object instances.

This identifier should then be passed on to GenerateReg Return Values: Create a Non-visual powerbuilser. Create the appropriate registry file.

REG file using a unique identifier.

Merge the registry file into the registry on the target machine. Application established successfully Notes: Installation and Deployment Issues PowerBuilder Installation Two new files need to be included in the both PowerBuilder development environment installation and the run-time deployment installation.

Limitations and Other Considerations Are automation objects pCode or machine code? Do I have a choice? OLE Automation created by PowerBuilder may be either pCode or Machine Code objects For objects accessed through programmatic identifiers in the registry, the registry entry indicates the binary type of the object pCode or machine code.

Poweruilder I mix pCode and machine code objects?
