Connect Venapp to the model

I built my Venapp screen using the example, but how can I connect it to my models?

If you look at the opening commands from the Venapp you will see the SPECIAL>LOADMODEL command - this needs to refer to your model.

The idea is when I do that it didn't show my variable so what is the problem?

Not sure exactly what you mean by not showing your variables, but if your graphs are blank the cause may be that you haven't loaded a dataset (MENU>LOAD_RUN or SPECIAL>LOADRUN) or started a synthesim simulation. Can you describe your problem more fully, or post some code?

Tom,
I was checking some examples and when I need to use SPECIAL>LOADMODEL command the model should be in VGD format? how?

.vgd format is for custom graphs, which you can load via SPECIAL>READCUSTOM (but you don't normally need to do this if your custom graphs are in your model file).

LOADMODEL takes a model in .mdl, vmf, vpm, or vpa format (see the online help, DSS reference supplement, chapter 5).
