Right now I'm trying to speed up the number of wavefrom  per second. I'm using your  drs_exam.cpp program you wrote as my basic program. When you wrote it you used the function "b->StartDomino()" inside the loop, which means that before every trigger you gave him a command to start the domino-wave.

From  the "DRS4 datasheet" (page 8) I understand that I can bypass the need to restart the  domino-wave by using "b->SetDominoActive(1)" and "b->SetDominoMode(1)", but when I tried it didn't work (the waveform I got every readout remain the same which means the dominowave froze after the first readout).

Am I understanding wrong or do I need to add somthing more\else so the domino-wave will not stop after each readout? is there any hazard by doing that, as mentiond in page 8 of the the datasheet?

The Domino wave anyhow is always active in mode 1, but you have to enable the writing to the memory cells (via the DENABLE signal). This is done with the b->StartDomino(). You are right that this call takes about 1ms over USB 2.0, so avoiding it would speed up the DAQ by about a factor of two. I have some plans to implement an automatic restart in firmware of the evaluation board, but I won't have time for that until fall of this year.
