Request for guidance on VC application development

[emagaoga@yahoo.com]

I am starting to develop a daq application using VC++ envitoment. I am using the PC-6024E card by NI.
My application must:

1.Aquire a voltage signal
2. Plot a chart for the signal
3. write to spread sheet.

I will be including fitting/interpolation funtions in the end.

Please give me some guidance on the approach, the tools(example codes), and other useful resources that can make the appliaction quick and simple to develop

your sincerly

Evans;

The slice of the application that interfaces with NI product is the Data Acquisition part.
To solve that portion of the application, you can refer to one of the NI-DAQ shipping examples named DAQDoubleBuf.c that you can find at C:\Program Files\National Instruments\NI-DAQ\examples\VisualC\AI.
That example shows how to do a continuous analog input acquisition. You can then, modify that example and include the plot and save to spreadsheet file portions of your entire application.

To expedite those two tasks, take a look at NI Measurement Studio product. The Measurement Studion is a set of ActiveX objects one can just configure to accomplish tasks such as the ones you mentioned.
