Body
I have a function that checks for other players' movement on the map and adjusts their position accordingly and it also checks that if the player just entered. <pre><code>void mapManager::checkForOtherPlayerMovement(int plyId) { sf::Packet receivedPacket; std::vector<player>::iterator it; player pl(0,0,1); if(socket->Receive(receivedPacket) == sf::Socket::Done) { int header; receivedPacket >> header; switch(header) { case PACKET_PLAYER_DISPATCHNEWPOSITION: { receivedPacket >> pl; std::cout << pl.plyId << std::endl; if(plyId != pl.plyId) { try { if(pl.plyId != 0) { std::cout << "DEBUG1" << std::endl; players->at(pl.plyId-1).posX = pl.posX; players->at(pl.plyId-1).posY = pl.posY; } else { std::cout << "DEBUG2" << std::endl; players->at(pl.plyId).posX = pl.posX; players->at(pl.plyId).posY = pl.posY; } } catch(const std::out_of_range& oor) { std::cout << "Added new player!" << std::endl; players->push_back(pl); // This crashes } } break; } case PACKET_PLAYER_DISPATCHENTEREDMAP: { break; } } } } </code></pre> So basically the crash happens when a new player connects to the server and the game needs to add it inside the vector. Strange thing is that it didn't crash on visual studio 2010, but crashes when I changed to vs 2012 so I must be doing something wrong. EDIT: Here is how the players vector is created mapManager.h <pre><code>std::vector<player> * players; </code></pre> mapManager.cpp <pre><code>players = new std::vector<player>(); </code></pre> Here I use the players vector <pre><code>void mapManager::drawOtherPlayers(int plyId, player *ownPlayer) { ownPlayerSprite->SetPosition(ownPlayer->getX(), ownPlayer->getY()); window.Draw(*ownPlayerSprite); for(std::vector<player>::iterator it = players->begin(); it != players->end(); ++it) { spriteToDraw->SetPosition(it->posX,it->posY); window.Draw(*spriteToDraw); } } </code></pre> My player class: <a href="http://pastebin.com/LJhQdFpL" rel="nofollow">Player.h and player.cpp</a>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
