Not exactly. Comment ça va ? or Ca va ? means more or less "How are you?"
Your friend just asked you how something went down. "How did it go?"
You're right, of course, PepinMalin. I was thinking that since it was a text message that her friend must be using the present for the past; otherwise why tap out so many letters when Comment ça va would do? But I should have stated that, and I didn't. Thanks for the précision !"Comment ça se passe ?" is closer to "Comment ça va ?", but it refers to a specific situation in which the interlocutor is, like living in a new town or being in a relationship. If she wanted to ask how something went down, she would have written "Comment ça s'est passé ?". I guess "How is it going?" is a good translation for "Comment ça se passe ?".
