[Paraview] First trial file does not work-help!

I'm not sure I understand what you are asking. I think you want to show the two blocks with different representations (outline and surface, respectively). If you take a look at the Multi-block Inspector (View → Multi-block Inspector) you can find controls to add different display properties to different blocks. Unfortunately, you are not able to set different representations on different blocks. Here is a way around the problem though:
1. Add the Outline filter to the reader (Filters → Alphabetical → Outline). You will now see geometry, gauss points, and outlines around both.
2. Select the reader in the pipeline browser, go to the Multi-block Inspector, right click on the block for geometry, and select Hide Block.
3. Select the Outline filter in the pipeline browser, go to the Multi-block Inspector, right click on the block for gauss points, and select Hide Block.

Thanks, that works very well. Since I just learn at the moment I prefer to work on text editor. I guess when I integrate it to my FE solver in c++, it will be ok from now on.
The only thing is that I think it is not possible to make one show the outline (geometry) and the other gaussian points at the same time in paraview.
Do you know any way to do it? Because otherwise I will be forced to work on separate files unfortunately.

Many text editors use a “smart quotes” feature that replaces the straight quote to a bent open or closed quote. The VTK reader only accepts the straight quotes (ASCII character 34).
