The is a common runtime issue that typically surfaces when a PowerBuilder application fails to call a function on an external OLE (Object Linking and Embedding) object. Unlike standard coding errors that appear during compilation, R0035 occurs while the application is running, often because a required external component—like a DLL, OCX, or an automation server—is missing, corrupted, or not properly registered on the target machine. Common Causes of Error R0035
If the cause remains unclear, you can run your application from the command line with the /pbdebug switch. This generates a .dbg trace file that records every line of code executed, helping you pinpoint exactly which line triggers the R0035 error. powerbuilder application execution error r0035
: If the app works in your development environment but fails after deployment, ensure all runtime DLLs and supporting files are included in the application folder or the system path. The is a common runtime issue that typically
: 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 This generates a
: Use the Windows Command Prompt (as Administrator) to manually register necessary components using the regsvr32 command. Example: regsvr32 MSCOMCT2.ocx
: Moving an application to a new virtual machine or a different OS (e.g., Windows 10 to Windows 11) can break OLE connections if the supporting libraries are not present.
