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 . powerbuilder application execution error r0035

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 .

Troubleshooting PowerBuilder Application Execution Error R0035

If you are a PowerBuilder developer or an IT administrator, encountering the "Application Execution Error R0035" can be a frustrating roadblock. This error typically surfaces during the application startup phase or when a specific window is being instantiated, essentially halting the program before it can perform its intended tasks.

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?

In the PowerBuilder ecosystem, execution errors prefixed with "R" refer to Runtime Errors. Specifically, Error R0035 indicates a "Link to reference failed" or an "Invalid object reference."

Essentially, the PowerBuilder Virtual Machine (PBVM) is trying to access a specific object, function, or library mentioned in the code, but it cannot find the definition or the "link" to that object is broken at runtime. Common Causes of R0035 There are three primary reasons why this link fails:

Missing or Mismatched PBLs/PBDs: The application is looking for a compiled library (PBD or DLL) that isn't in the system path or the application folder.

Version Mismatch: You might be running a newer version of the application executable (EXE) with older versions of the runtime libraries (PBVM DLLs), or vice-versa. Error R0035 = PowerBuilder Virtual Machine failed to load

Corrupt Object Definitions: An object (like a DataWindow or a User Object) within a library may be corrupt or failed to compile correctly during the build process.

Deployment Path Issues: The application’s search path (Environment Path) does not include the directory where the PowerBuilder runtime files are located. Step-by-Step Solutions 1. Verify the Runtime Files

The most common culprit is a missing runtime DLL. Depending on your version of PowerBuilder (e.g., 2019, 2022, or older versions like 12.5), ensure the following files are in the same folder as your EXE or in the Windows System Path: pbvm.dll pblib.dll pbtra.dll

Corresponding database drivers (e.g., pbtra.dll for SQL Server or pbor6.dll for Oracle). 2. Check the Deployment Search Path PowerBuilder looks for its libraries in a specific order: The directory where the EXE is located. The current directory. The Windows System directory. Directories listed in the PATH environment variable.

Ensure that if you have multiple versions of PowerBuilder installed on a machine, the System PATH isn't pointing to an older version’s Shared folder, causing a conflict. 3. Perform a "Full Build" and Re-deploy

Incremental builds can sometimes lead to "ghost" references where the compiler thinks an object exists in a certain state, but the compiled PBD doesn't match. Open your PowerBuilder IDE. Go to the Project Object. Select Full Build instead of Incremental Build. Regenerate all PBDs and the EXE. 4. Inspect the Application Log

If the error occurs on a client machine but not on your development machine, use a tool like Process Monitor (ProcMon) from Microsoft Sysinternals. Run ProcMon and filter by your application's EXE name.

Look for "FILE NOT FOUND" results. This will tell you exactly which DLL or PBD the application is searching for right before it throws the R0035 error. 5. Validate DataWindow Objects

Error R0035 often triggers when a Window tries to open a DataWindow that hasn't been included in the PBDs. Check your PBR (PowerBuilder Resource) file to ensure all dynamically assigned DataWindows or images are explicitly included in the build. Conclusion

The PowerBuilder Application Execution Error R0035 is almost always a deployment or environment configuration issue. By ensuring your runtime DLLs match your EXE version and performing a clean "Full Build," you can resolve the majority of these cases.

If the problem persists, verify that the client machine has the correct Visual C++ Redistributable packages installed, as modern PowerBuilder runtimes depend on these to execute their core C++ logic.

This error can appear in any version (from PB 6.5 to PB 2022), but the DLL filename varies:

| PowerBuilder Version | Core DLL | |----------------------|-----------| | PB 6.5 | pbvm65.dll | | PB 7.0 | pbvm70.dll | | PB 8.0 | pbvm80.dll | | PB 9.0 | pbvm90.dll | | PB 10.5 | pbvm105.dll | | PB 11.5 | pbvm115.dll | | PB 12.5 | pbvm125.dll | | PB 15.0 | pbvm150.dll | | PB 2017 | pbvm170.dll | | PB 2019 | pbvm190.dll | | PB 2021 | pbvm210.dll | | PB 2022 | pbvm220.dll |

Go to your Application Object (app_name). Find the SystemError event. Add the following code to catch the details:

// In the Application Object's SystemError event
Messagebox("System Error Occurred", &
    "Number: " + String(error.number) + "~n" + &
    "Text: " + error.text + "~n" + &
    "Window/Menu: " + error.windowmenu + "~n" + &
    "Object: " + error.object + "~n" + &
    "Object Event: " + error.objectevent + "~n" + &
    "Line: " + String(error.line))

Note: Sometimes R0035 is so severe it prevents even the SystemError event from firing cleanly, but usually, this will tell you exactly which object and script line caused the crash.
