Problem with making picture invisible

[Albert.Geven]

Hi here is my first attempt

[nousome]

Thanks very much, I didn't think like that.
Now for randomizing sequence, have I to write this in another Vi knowing that I have a criteria for stoping the random number.

Indeed, a click on one picture is correct and a click on another picture displayed is wrong (it is for this reason, I called them S+ and S-).  The participant have to click on the 4 presentations of S+ (and of course click the number of times required on the rectangle) two times before another phase of testing begins.

I don't know if it is clear for you?

building the array with pictures to select and timing should indeed be done in another vi.
change the constant array into a control and make it appear in the connector (upperleft is nice)
by the way always use the 4 2 2 4 connector witk lower left for error in and lower right for error out.

the result of your vi can than be brought to an evaluation vi that calculates or stores the result.

Hi,

I have tried to change name of element in the cluster but I don't succeed. I wonder why?
I want to do that because I want to program when the user clicks on the wrong figure (S-), black panel results and when the user clicks on the right figure (S+), 10 sec of opening of paint results (I don't succed for the moment to stop painting with system exec.
I send here the 3 Vi need to do this job. 

Thanks in advance for your help.

1) why use paint?

2) why change the frontpanel to resize so that I cannot debug easily anymore

3) why change the left value to right so it is useless

4) what are you trying to do?

5) read the chapter on typedefinitions and you see how to change names

1) why use paint?

I use paint and also after windows media player for playing sound and video for the need of my experiment. It is for rewarding good responses and timeout for punish bad responses.

2) why change the frontpanel to resize so that I cannot debug easily anymore

Sorry I resized the front panel to reajust with my screen.

 3) why change the left value to right so it is useless

Ok

4) what are you trying to do?

I want to adjust events as displaying paint or vi timeout contingent to mouse events in the S+ (S+ HE or S+ Le) or S- picture.  

5) read the chapter on typedefinitions and you see how to change names 

Ok thanks.

Hi Albert,

You can take the first version you create for debugging if you want. Thanks in advance.

Hi,

I have some experiments to conduct, and I would like to program opening and closening of external applications like paint or word.

This means that I would like, for example, opening paint for 20 seconds and then close paint and return to the program.

Is it possible?

Thanks.
