Property Value

My_ResX\My Sequence

Note:
For a node to receive context help from a .resx file, the file must exist in the following location: <Application Data>\User Interface\ResX\en

.resx files are useful if you want to store the context help strings for a real-time sequence in a separate place from the code itself. For example, if you have a designated technical writer, you can give that person one file to work in instead of all the code for your real-time sequence.
