It has no block diagram

[Valarauca]

Vi version 5.1 cannot be converted to current labVIEW verion 8.0 because it has not block diagram.

The Vi was orginally made. on windows98, I'm attempting to open it in windowsXP (with Labview8).

Full error message

I'm just wondering what to do. (I'm attempting to convert the the old 5.1 VI up to a version around 10/12/13 so i can rebuilt it for newer then windows 98 Opperating systems, porting legacy code yay). So should I install labview7 on a windows98 box?

You cannot do a single thing with a VI and no block diagram except run it with the version it was created with. You have to have a block diagram in order to upgrade.

The OS is absolutely irrelevant.

What Happens When I Save My VI and Remove Diagrams?

[0utlaw]

Hello Valarauca,

As Dennis indicated, the VI is in this state because someone intentionally removed the block diagram when saving it.  This KnowledgeBase has more information on how to do this and what it implies:

There is no way to upgrade or recover the VI as-is unless you have the original source as well.

Regards,

The VI's that are listed as missing their block diagrams, have their block diagrams (on the orginal windows98 computer), which isn't the orginal machine that authored them (it was just a distrubution of the source code).

Most of these VI's are related to legacy NI DAQ which the VI's are just wrappers around calls to DLL's. So I'm working on it hopefully will find a decent solution.

Explain exactly what you mean. Your diagramless VIs are calling traditional DAQ functions or you are trying to open traditional DAQ functions? If you are trying to open old traditional DAQ functions, that simply makes no sense. You install the latest traditional DAQ driver, The VIs in that will open just fine in any current version of LabVIEW.

My diagramless VI's ARE traditional DAQ functions.

>that simply makes no sense

Welcome to the past 2 days of my life. All the VI's that are listed as block diagram-less on windowsXP or Windows7 are directly from the Data Acquition palette in Labview5.0 (windows98).

I am moving foward and installing the latest verion of the traditional DAQ that supports my hardware.

Hi Valarauca,

Were these Legacy DAQ functions re-saved at some point or manually copied from the old machine?  If the driver has not been installed, you should be seeing a missing functions error rather than an unable to load error.
