Question

Background:
I am trying to print vi documentation to html. When using the standard Labview print function, you get by default the control's label in the documentation, not the caption. This is a problem for me because my captions and labels are different because I change the captions for different languages. To get around this, I thought I'd write another vi to print documentation for each vi in an llb directory programatically. But before I'd print the documentation, I'd open up a reference to the vi in the llb, get a refence to the panel, get all control references, and for each control, replace the label text with the caption text. Then print the documentation and c
lose without saving the original vi.
Problem:
For some controls, (when the label text is not the same as the caption text) when I try to read the control caption and write it to the control label, I get the above error and LabView crashes. This is very annoying.
Anybody have any thoghts or suggestions. I will try to narrow down the problem into smaller vi's and post these.
Thanks.

Attached are two vi's. One is language.vi. There is a control on there that has different text for the label and the caption. Now run test.vi and select language.vi. Labview crashes. At least it does for me. If you highlight execution, you will see it crashes when it tries to write the caption to the label. I'm using version 6.1. Thanks for any help.
