Problem with Append Front Panel Image to

In my main application, I use a sub-panel to display a another front panel (from another VI).
When I generate my html report from the main application, I want to "capture" the front panel image (contained in the sub-panel).
But I only get a big grey image in my html report.
I use the the Append Front Panel Image to, which is referenced to my external vi.
Any idea of the problem?

I had no problem generating an image of the front panel with a subpanel containing a VI.  I have attached two VIs showing how I did it.  Just detach them both to the same folder and run generate  It will generate the HTML file in your c:\temp folder (make sure that folder exists before running the VI).  The VIs are saved in LabVIEW 7.0 format...I have the Report Generation Toolkit installed in my LabVIEW 7.0, so you may need to re-link the subVIs if you don't have that toolkit installed.

Let me know if this helps, or if you're still having trouble.  If you are still having trouble, attach a sample VI demonstrating the problem so I can help you further.

Good luck,

P.S. - I also tried this in LabVIEW 8.2 with no problems.

Ok, tnx for the example.

But I want to output to the report only the front panel that is shown inside the sub-panel (not the main application front panel). Can it be done?

I think the easiest way to do this would be to use the Append Control Image to instead of the Append Front Panel Image to append the image of the subpanel to the report.  If you don't like that idea, I'm pretty sure the Append Front Panel Image to takes in a VI Reference, so you can just wire a reference to the VI that you're hosting in the subpanel.

Yes, I have tried the Append Control Image to, and connected the sub-panel reference to it, and it works: from your generate, I call my vi (instead of in your example.

Still it does not work from my main application... There must be a glitch somewhere in my report controls....

At least, I know it can work 🙂

Tnx again.

The only thing I can think of is that perhaps you are unloading the VI from the subpanel before you take the image?  Or perhaps you're taking the image before loading the VI?  Also, you could check to see if an error is occurring upstream anywhere, which would cause no image to be appended at all.

I hope you can figure it out,
