Powerbuilder Application Execution Error R0035 95%
PowerBuilder Application Execution Error (R0035) typically occurs when an application fails to call or execute a function on an external object , such as an OLE control, a COM object, or a DLL Appeon Community Core Cause
The error indicates that the PowerBuilder runtime cannot find or communicate with a specific method or property of an external object. This is often due to: Appeon Community Unregistered Components
file required by the OLE object is not registered on the target machine. Missing Dependencies
: A required system file or third-party library is missing from the application path or system folders. Mismatched Versions
: Upgrading components (like Crystal Reports or Office) without updating the calling code or runtime environment. NULL References
: Attempting to call a function on an object that failed to initialize (e.g., ConnectToNewObject returned an error code but the script continued). SAP Community Common Fixes Register the Control : Manually register the failing component using for OCX/DLL files or for .NET COM DLLs. regsvr32 "C:\Path\To\YourControl.ocx" Verify Registry
: Check that the COM object class (CLSID) exists in the Windows Registry on the machine where the error occurs. Check Return Codes
: Ensure your code validates the connection before calling functions. powerbuilder

Missing or Unregistered Components: The required library (DLL, OCX, or VBX) is not registered on the system or is missing from the application path.
Automation Timeout: The OLE procedure call took longer than the internal timeout period (default is 5 minutes). If the request is expected to be long, the default may need adjustment.
Initialization Issues: Attempting to call a function on an object that has not been properly instantiated or connected via ConnectToNewObject.
State Errors: Calling a specific function when the object is in an invalid state, such as trying to print an image before one has been loaded. Resolution Steps
Register the Component: Manually register the relevant control using regsvr32 (e.g., regsvr32 mscomct2.ocx).
Adjust Timeout: Use the SetAutomationTimeout function to lengthen the allowed wait time for OLE calls if the server is slow.
Verify Object Connection: Ensure the OLEObject variable is successfully connected to the target application or control before calling its methods.
Debugging: If the cause is unclear, advanced users can use WinDbg to attach to the PowerBuilder process and capture the call stack at the moment of failure. powerbuilder application execution error r0035

PowerBuilder Application Execution Error R0035 The PowerBuilder error R0035 is a runtime exception that occurs when an application fails to execute a function on an external object, such as an OLE (Object Linking and Embedding) control, an OCX, or a COM server. The primary cause is typically a communication failure between PowerBuilder and the external component, often because the component is missing, unregistered, or has crashed. 1. Root Cause Identification
The R0035 error, specifically titled "Error calling external object function," is triggered when the PowerScript engine successfully finds the external object but the subsequent function call fails.
Unregistered or Missing Components: The required .ocx or .dll file is not registered on the target machine.
Component Instability: The OLE server or external process has "died" or crashed before the function could be executed.
Mismatched Bit-ness: Using a 32-bit PowerBuilder application to call a 64-bit external object (or vice-versa).
Dependency Issues: Missing prerequisites like the Microsoft Visual C++ Redistributable or supporting system DLLs. 2. Immediate Recovery Steps
To resolve this error, follow these technical verification steps:
Register the External Control: Use the regsvr32 tool to register the component manually. Open a Command Prompt as Administrator. Run: regsvr32 "C:\path\to\yourcontrol.ocx".
Verify Object Existence: Before calling the external function, wrap the code in an IsValid() check to ensure the object is instantiated.
Use Error Handling: Wrap the call in a TRY-CATCH block using the OLERuntimeError exception to prevent the application from crashing and to capture a more descriptive message.
Regenerate Objects: If the error occurs in the IDE, right-click the object in the System Tree and select Regenerate to fix potential compilation mismatches. 3. Diagnostic Commands and Tools

PowerBuilder Application Execution Error R0035 typically indicates a failure when calling a function from an external object, such as an OLE, COM, or ActiveX control . This runtime error occurs when the application successfully references an object but fails to execute a specific method or property call on it . Common Causes
Unregistered Controls: The target OLE/ActiveX control (e.g., .ocx or .vbx file) is not registered on the current machine .
Missing Prerequisites: System-level files required by the control, such as specific Windows components (e.g., MSCOMCT2.ocx), are missing .
Incorrect Function Reference: The function name is misspelled, or the arguments provided do not match the external object’s API .
Environment Mismatches: A 32-bit application attempting to call a 64-bit component, or vice versa, often leads to execution failures . Troubleshooting & Fixes
To resolve this issue, you can use several methods depending on the specific cause:
Register the Control: Manually register the external file using the command prompt. Users on the SAP Community suggest navigating to the control's directory and running regsvr32 controlname.vbx or .ocx .
Verify External Objects: Ensure the COM object exists in the Windows Registry. Expert advice from the Appeon Community recommends comparing registry definitions between a working and a failing machine .
Check Function Definitions: Consult the documentation for the external object to ensure the function you are calling actually exists and is being accessed via the correct proxy, such as an OLEObject .
Implement Error Handling: Use TRY-CATCH blocks to capture OLERuntimeError exceptions. This allows you to inspect the Description property for more specific details about why the call failed .
Regenerate Objects: If the error occurs in the IDE, try right-clicking the object and selecting Regenerate to ensure it is compiled correctly against current libraries . Summary of Solutions Issue Type Recommended Action Missing Registration Use regsvr32 on the target .ocx or .vbx . Dependency Failure Install missing Windows components like MSCOMCT2.ocx . Logic/API Error
Verify function names and parameters against the object's documentation . Code Stability
Wrap external calls in TRY-CATCH to prevent application crashes .

The PowerBuilder Application Execution Error R0035 is a runtime error that specifically occurs when an application fails to call a function on an external object, typically an OLEObject or ActiveX control. 🛠️ Error Definition Error Code: R0035
Message: "Error calling external object function [function_name]"
Primary Cause: The application is attempting to execute a method on an external server (like Excel, Word, or a custom OCX) that is either not initialized, not registered, or has crashed. 🔍 Common Root Causes
The error usually stems from one of the following environmental or structural issues: 1. Unregistered or Missing OLE/ActiveX Components
The .dll or .ocx file required by the application is not registered on the client machine. This often happens during deployment to a new environment.
Fix: Use regsvr32 to register the missing component (e.g., regsvr32 mycontrol.ocx). 2. 32-bit vs. 64-bit Mismatch
A 32-bit PowerBuilder application cannot call a 64-bit OLE object, and vice versa. This is a frequent issue when migrating older applications to 64-bit environments.
Fix: Ensure the bitness of the application matches the registered version of the external object. 3. Uninitialized OLE Object
The OLEObject variable was declared but not properly connected using ConnectToNewObject or ConnectToObject before the function call.
Fix: Verify that the connection return code is checked before calling methods: powerbuilder
li_rc = myOleObj.ConnectToNewObject("Excel.Application") IF li_rc < 0 THEN // Handle connection error Use code with caution. Copied to clipboard 4. Out-of-Date Object Compilation
The calling object or its ancestor is "out of date" in the PowerBuilder library (.pbl), leading to a signature mismatch at runtime.
Fix: Perform a Full Build or manually Regenerate the object and its ancestors in the IDE. 🚀 Troubleshooting Steps

Here’s a comprehensive review of the PowerBuilder Application Execution Error R0035, including what it means, common causes, symptoms, and step-by-step troubleshooting solutions.
What Does Error R0035 Actually Mean?
To understand R0035, you must first understand how a compiled PowerBuilder application runs.
- PBD Files (PowerBuilder Dynamic Libraries): These are equivalent to DLLs but specific to PowerBuilder. They contain compiled objects (windows, user objects, functions, datawindows).
- Runtime Resolution: When you launch a PowerBuilder EXE, it does not contain all the code. It dynamically loads referenced PBDs and DLLs (like
pbrtc105.dll,pbvm105.dll, etc.) from the file system or network path.
Error R0035 triggers when the PowerBuilder Virtual Machine (PBVM) cannot locate, access, or properly load one or more of the required PBD files listed in the application’s library list.
In simple terms: The EXE knows it needs module_a.pbd, but when it goes looking for it, the file is missing, corrupted, inaccessible, or incompatible.
1. Verify the PBR file exists
- Check the application’s installation directory for the
.pbrfile referenced in the error (if the error specifies a filename). - If missing, copy it from the development environment or original distribution package.
