The victim is the one identifying the assailant/guilty party from the line up-not in it.
A victim is not just a victim. The victim will be the State's number 1 witness, as the victim of the crime. Police need an eyewitness identification of whether a person is or is not the one who committed the crime. However, usually this question is NOT spoken. Instead, the police use a lineup of innocent persons along with one suspect.
A show up is right away, when a witness or victim is taken to see the suspect, and a line up is multiple person with similar features behind the window.

only if that person is being charged with a crime.
In the United States, criminal charges against a defendant are brought by the state, not by victim(s) of the crime. While a victim may provide a statement to the police which leads to the alleged perpetrator being charged with a crime, it is the police, not the victim, who actually file the charges, and the district attorney, not the victim, who prosecute. Therefore, yes, the police can and sometimes do file charges even when the victim(s) of the alleged crime choose not to cooperate with the police. This happens, for example, in domestic violence cases, where the victim of the domestic violence may be cowed by an abusive partner or spouse into not pressing charges, but the police might still pursue them.
