R0035 Upd: Powerbuilder Application Execution Error

In the PowerBuilder ecosystem, this error indicates a severe memory management failure. It occurs when the application attempts to read from or write to a memory address that it does not have permission to access, or an address that no longer points to a valid object.

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 most common cause of R0035 is that an external OCX (OLE Control Extension) or DLL file required by the application is not registered in the Windows Registry. Without proper registration, PowerBuilder cannot load the control, leading to an external object call failure. 2. Missing or Corrupt Files powerbuilder application execution error r0035

Troubleshooting PowerBuilder Application Execution Error R0035

Even if a .NET assembly or C++ DLL is successfully registered via RegAsm or RegSvr32 , the external component itself might have unfulfilled dependencies. If a .NET COM wrapper relies on a specific version of the .NET Framework or a third-party Java runtime that is missing on the client machine, the method call will fail internally and return an R0035 error to PowerBuilder. 4.

: Wrap your OLE calls in a TRY-CATCH block. Catching the OLERuntimeError exception allows you to inspect the "Description" property, which often provides more specific details about why the call failed.

Resolving this error requires identifying the underlying trigger. The most frequent culprits include: 1. Missing or Mismatched Runtime DLLs

: In PowerBuilder, use the OLE Browser (found under Tools -> Browser -> OLE tab) to verify that the properties and functions you are calling actually exist in the registered object. Debugging with pbdebug
