Error 1 input parameter is invalid generate user event

[olivier66]

HI
I have got an issue running my application I have created an user event in the main VI and generate it in a first subVI in order to path value changes on some user completed fiels and when I run the main VI I receive an "error 1 input parameter is invalid at generate user event"
See files attached
Thanks

Could you give some more information? How are you wiring the generate user event.vi? Maybe you could take a screen shot of that actual VI in your code.

It seems like something you are wiring to generate user event is not in the correct format.

Before I could even be able to begin advising you on the issue you are asking about, there are major structural problems in your code. The block diagram is huge - and that is NOT a Good Thing. It is also very difficult to read due to the colorization of the structures. Green scalar boolean wires are very difficult to see on a blue background. My sense is that you started coloring things because you were getting lost on the diagram.

The solution is modularization - creating small, reusable routines (subVIs). The required functionality for these subVIs will become apparent through as you decompose the application's functionality into its constituent components, sub-components, sub-sub-components, etc.

Also be sure to utilize dataflow to manage the execution of the code, not artificial structures like sequences, and connect up the error handling. Your application can't tell you its broken if there is no error handling.

When you post screen shots, make sure they are truly .png files.  Although your files have an extension of .png, they are actually .bmp which makes them huge and slower to download.
