Change sample mode in DAQmx and terminal configuration

[oly]

Hi,

I am studying "Timing and Synchronization Features of NI-DAQmx" from the following link,

 http://zone.ni.com/devzone/cda/tut/p/id/4322 

Could anyone tell me in Figure 2, how to do input terminal configuration in the "DAQmx creat virtual channel" part? Shoud I just double click on the icon to change it? Or there is some way that I can show it in the block diagram like the sample mode in the DAQmx part?

One more question, in the DAQmx timing part, how can I put "Continous Samples" there? Is it from the function pallette? Thank you.

Hi Oly,
        To do the input terminal configuration in the "DAQmx Create Channel" you'll need to either create a constant or a control on that VI.  When you hover over a VI, like the  "DAQmx Create Channel" VI, you'll notice that little dots appear around the edge of the square.  When you hover your mouse over these dots, you mouse pointer will appear to be a spool of wire/thread at which point you can right click your mouse and select "create» constant" or "create» control".  If you create a control, you'll have a user control on your front panel, where as if you create a constant, you'll have a pull down list on your block diagram. 
 
The same goes for the Continuous Samples, simply hover over the VI, right click on the corresponding "dot" and select to create a constant.  
 
In case my instructions aren't clear, I attached pictures of how to go about doing this, the first is to show the "dots" I'm talking about around the VI and the second picture shows the option to choose after you right click on the dot.
 
Happy Programming!
