CVI- activeX

[Flutter]

I have started looking at and working through the Active X examples (e.g. 3DGraphAxis). The CA_ functions are included in the CVI help documentation but the CW3D__ functions not. 1) What is the best way to get to know the ActiveX controls (working through the examples?) 2) Where can I get help on the CW3D functions ? 3) Where can I find any relevant documentation to get me going?

Regards

Hi Flutter,

The help for the CW3DGraph is not integrated into the CVI help because this is really a Measurement Studio control. The simplest way to find the help is to use the function panels for the associated CW3DGraph library. You can also access the help directly: C:\Program Files\National Instruments\Shared\MeasurementStudio\Help\cw3dgraph.chm

Thanks for your response so far. However, when looking at the supplied CVI examples (e.g. 3DGraph.cws) the code contains, for example,  CW3DGraphLib__DCWGraph3DGetPlots (graphHandle, NULL, &plotsHandle) and the help  file that you referred me to does not provide any clarity on any CW3DGraphlib functions.By right clicking on the a control on the 3DGraph control properties display (What's this?) I am directed to  MS Help file that I need to install. However, this file format is not supported anymore. In addition, this particular machine is not connected to the net so I hope that the help is not on-line.

Thanks and regards

Hi Flutter,

The cw3Dgrph.chm file is the only help we have available for this control. The properties and methods obvioulsy don't match 100% with the function names in CVI. This is because the CVI library is a wrapper around the original library that was developed for C++ and VB. The simplest way to use this help is to use the function panel right-click method. When you do this, are you not taken to the cw3Dgrph.chm file? Right-clicking on individual parameters in these function panels will probably not display any help. But if you right-click in a blank area of the function panel, it will take you to the appropriate page in the chm help. Note that for the example function you provided, this will link to the Plots property rather than the getPlots function because the getPlots function only exists in the wrapper.
