Issue Details

In LabWindows™/CVI 2009, programmatically duplicating or printing graph controls containing plots may cause memory corruption and eventually lead to a crash in my program. How can I resolve this issue?


This issue affects users whose version of the LabWindows/CVI Run-Time Engine, cvirte.dll, is This issue is caused by any functions that print or duplicate panels that contain graphs with plots, or print or duplicate graph controls that contain plots. Other functions that can cause this issue when used in conjunction with graphs with plots are:
  • GetScaledPanelDisplayBitmap
  • GetScaledCtrlDisplayBitmap
  • CopyTabPage
  • InsertPanelAsTabPage
You can resolve this issue by installing the patched version of the LabWindows/CVI 2009 Run-Time Engine found here. This patch will update the LabWindows/CVI Run-Time Engine to include a fix for this issue.
