Application Execution Error R0035 in PowerBuilder is defined as: "System error."

This is a generic, low-level error indicating that the application attempted to perform an invalid operation at the system level. It is often the "catch-all" error when PowerBuilder encounters an issue it doesn't have a specific error code for.

Here is a comprehensive guide to troubleshooting and resolving R0035.

Step 3: Install or Copy Missing Files

  • Option A (Recommended): Run the official PowerBuilder Runtime Packager (.msi or .exe) provided by the application vendor.
  • Option B (Manual): Copy all required DLLs from a working PowerBuilder installation or runtime distribution into:
    • The application’s own folder, OR
    • C:\Windows\System32 (for 64-bit) or SysWOW64 (for 32-bit on 64-bit Windows), OR
    • A folder listed in the system PATH.

2. Invalid DataWindow Operations

R0035 frequently occurs during DataWindow processing if the buffers are in an unexpected state. The application’s own folder

  • GetItem/SetItem Errors: Trying to get or set data in a row or column that does not exist, or accessing a deleted row.
  • Buffer Issues: Accessing the Delete! buffer when it is empty.
  • Fix: Always check RowCount() and FindRow results before manipulating data. 
    Long ll_row
ll_row = dw_1.GetRow()
If ll_row < 1 Then Return // Prevents crash if no row selected

    // Check column existence
If dw_1.Describe("my_column.Visible") = "!" Then Return

What is PowerBuilder Error R0035?
