Issue Details

  • LVMerge tool presents with Options such as “block diagram cosmetic changes” (as shown in image below). Are those options pre-settable in an ini file?
  • Are there any command line parameters like the LVCompare.exe can be used to configure LVMerge tool's Options Menu?


Unlike LVCompare.exe, there is no command line parameter available for LVMerge.exe to configure its Option Menu. There is also no INI file can be used to preset the Option menu configuration. The Option menu configuration can only be modified by user manually.

Additional Information

When you run LVMerge.exe's Support VI, which located at C:\Program Files\National Instruments\Shared\LabVIEW Merge\supportVIs,you will get Error 7 as illustrated by image below.
The LVMerge.ini file mentioned by the Error Source can be found in user's Temp folder. It will only be created when LVMerge.exe is called via Command Line and will be removed automatically once the execution is completed. The INI file does not contain any information regarding the Option Menu. It is used to temporary store the parameters provided by the user via Command Line during LVMerge.exe execution as demonstrated by image below.
