At its core, Error R0035 indicates a breakdown between the PowerBuilder runtime engine and an external component. PowerBuilder displays this popup message with the syntax: PowerBuilder Application Execution Error (R0035): Error calling external object function .
Confirm whether the program ID ("Word.Application", "Excel.Application", etc.) exists in the Windows Registry of the failing machine under HKEY_CLASSES_ROOT . Common Mitigation Scenarios and Solutions Scenario A: Unregistered .ocx or .dll Files
The most straightforward cause. The application’s library list contains a PBD file that does not exist in the application’s search path (current directory, system path, or specified path).
In this guide, we will break down what this error means, its common causes, and the step-by-step solutions to get your application back up and running. What is Error R0035?
The PowerBuilder Application Execution Error R0035 can be a frustrating issue, but by understanding its causes and applying the solutions outlined in this article, developers and users can resolve the error and ensure smooth PowerBuilder application execution. By following best practices and staying proactive, you can minimize the occurrence of the R0035 error and maintain a stable and efficient PowerBuilder development environment.
Understanding the cause is the first step toward fixing the R0035 error. The most common triggers include: 1. Unregistered External Controls (DLL/OCX)
The typically occurs when PowerBuilder tries to communicate with a Windows-level component or an external DLL and the interaction fails. The error message may look like this:
This error indicates that the PowerBuilder Virtual Machine (PBVM) or a critical DLL dependency required to run the compiled PowerBuilder application (EXE or PBD) is missing, corrupt, or inaccessible.
A prime example comes from the PowerBuilder community, where a user was trying to call a C++ DLL function with the signature void GetDecryptedFile(unsigned char** ppbFileContents) . Their PowerScript code ioo_my_ole_object.GetDecryptedFile(ref ls_content) would crash with an R0035 error. The issue was a pointer-to-pointer parameter that PowerBuilder does not handle directly. The community's recommended solution was to pre-initialize the string variable to a specific length using ls_content = Space(x) to allocate the necessary memory before the call, which can resolve the mismatch.
The PowerBuilder is a frustrating runtime error that generally signifies a failure when calling an external object, function, or method. Specifically, it often appears as "Error calling external object function," often related to OLE (Object Linking and Embedding), COM (Component Object Model) components, or external DLL calls that fail to execute within a PowerBuilder application.
Several factors can contribute to the occurrence of the R0035 error:
To understand why this error occurs, it is essential to look at how PowerBuilder interacts with external entities like Microsoft Excel, Word, Adobe Acrobat, custom .NET COM DLLs, or ActiveX components ( .ocx / .vbx files).
If you can provide more context (PowerBuilder version, exact error message text, and whether it happens on one machine or many), I can refine the troubleshooting steps further.
Whether the error happens on or just specific ones.
