If the external object's software was updated on the client machine, its public interface (API) might have changed. If a function signature was modified, renamed, or deprecated in the new version, PowerBuilder will look for the old method definition, fail to find it, and trigger the runtime error. 4. Invalid or Incompatible Arguments

Error R0035 is a runtime error that occurs when a PowerBuilder application fails to execute properly. The error message typically appears as:

is a critical runtime error that occurs when a PowerBuilder application fails to communicate with an external Object Linking and Embedding (OLE) server, a Component Object Model (COM) library, or an external Dynamic Link Library (DLL). The core error message text— "Error calling external object function" —indicates that PowerScript successfully recognized the OLE object container but failed to execute the specific method or function called within the external resource.

(x86/x64) are installed, as missing runtime DLLs often trigger execution errors during external calls. Adjust OLE Timeouts : If the error occurs during long-running tasks, use the SetAutomationTimeout() function in your PowerScript to increase the allowed time. Appeon Documentation 3.
