DPlot

In spite of the best effortd of mother nature, we are still high and dry in Canberra (1800 feet elevation). I do feel for those poor folk in Japan at the moment.

How do you get a diagram into these posts? I wanted to do that and couldn't see how you do it. A picture is worth a 1000 words

I'll ...

yeah, see, I'm trying to create a custom control for the Dplot structure....

do I need to create 100 NP unsigned longs?

like,

NP[0]
NP[1]
.
.
.
NP[99]?

Because that's what LabVIEW does when it wants to put an array that was in a structure in C into a cluster. it puts each element into the ...

In fact, if one has a little patience (I went to lunch), labview does its work and produces an lvlib with the required functions in it as VIs, except a few of the bitmap ones (further work). Dragging D plot Plot.vi onto a diagram and doing a "create constant" on the terminal for the Dplot structure ...

yeah, that makes sense. LabVIEW apparently is not able to convert a datatype directly if it's something like a structure with nested arrays.

So, those 3 functions that need arrays within the structures have undefined structures.

Here is the Plot() function:

I think that by "custom control" LabVIEW wants me to create a little box that takes inputs for each of the variables in those functions.

So, for example, in the Plot() function, there's a cluster called "DPlot" and it looks like it has the following variables:

Version
hwnd
DataFormat
MaxCurves ...

okay, I changed the clusters in those 3 functions to "custom controls" in the "Configure VIs and Controls" dialog.... but I don't know what I'm doing.

It worked for almost all the functions except the bitmap functions mentioned above, and 3 functions I think I need. I got the following error report:

Parsing header file warnings:
No errors/warnings occurred when parsing the header file.

The following errors/warnings occurred when generating the ...

this is cool.

I am using the "Import Shared Library" function in LabVIEW right now to create a vi. It's taking a while (it shows it to be about half-way complete, and the CPU is cranking...)

So, it eventually finishes what it is doing?

Basically, I want my LabVIEW data acquisition program to ...
