Compatability from Labview 5 to labview 7 express?

[Kura]

I am having a problem where I may have to write a VI on labview 5 on one computer, then move it to a second computer running labview 7 express. Are there any compatability issues I may have to deal with in doing this?

there is not supposed to any compatibility issues with version 5. You would have a problem going backwards from 7 to 5 but not from going from 5 to 7.At least that is the way it is supposed to work.

Right, I know that, but I really need to know if anyone has tried this and had successful results.

Hello Kura,

LabVIEW 7.0 will open and convert LabVIEW 5 VI�s. There are occasionally conversion issues, just depending on what is involved in the VI (the bulk of which being hardware issues). These issues can almost always be resolved by first upgrading to an intermediate version of LabVIEW (6.0 or 6.1 in this case) or having the correct and updated versions of hardware drivers. If you don�t have either of these versions, or run into other problems, I would be happy to convert VI�s for you, or help you resolve any other upgrade issues.

Have a nice day!

If any of your LabVIEW 5 VIs use report generation tools, they may not be compatible with higher versions. As the reports move between VIs, the older tools pass the text of the report. The newer tools pass references to the text to subsequent VIs.

When you upgrade, newer versions of LabVIEW substitute the new tools (they have the same names) but the run-time engine sees different (and incompatible) data being passed to the new VIs.

The solutions are to either rewrite your code to pass the correct data types to the new tools, or build a library of the old tools and force the run-time engine to use them.

Alright, but what exactly is a report generation tool?
