    <p>So firstly, here's my declaration and initialization:</p> <pre><code>int** GameField = 0; GameField = new int*[mapsize]; for(int i = 0; i &lt; mapsize; i++) GameField[i] = new int[mapsize]; for(int j = 0; j &lt; mapsize; j++) for(int i = 0; i &lt; mapsize; i++) GameField[i][j] = 0; </code></pre> <p>Now i'm trying to insert data with a simple command:</p> <pre><code>if(!(Player1.find(Move) == Player1.end()) &amp;&amp; iter&gt;0) { GameResult=1; }else { Player1[Move] = 1; GameField[Move.first][Move.second]=1; if(WinCheck(Player1, Move, x, mapsize)) GameResult = 1; } </code></pre> <p>Simoultaneously i insert the data into an STL map. Visual Studio has no native display for dynamic data, so i'm unable to view the content of the table. Tried watching memory but it's pretty hard to make sense of it. There is a part of program that seems to be working till a certain point:</p> <pre><code> bool CheckIfMovePossible(int **GameField, pair &lt;int,int&gt; &amp;Move, int MapSize) { int x = Move.first; int y = Move.second; bool Neighbour = false; if(GameField[modulo(x+1,MapSize)][y]==(1||2)) // po prawej Neighbour = true; if(GameField[modulo(x+1,MapSize)][modulo(y+1,MapSize)]==(1||2)) Neighbour = true; if(GameField[modulo(x+1,MapSize)][modulo(y-1,MapSize)]==(1||2)) Neighbour = true; if(GameField[x][modulo(y+1,MapSize)]==(1||2)) // x Neighbour = true; if(GameField[x][modulo(y-1,MapSize)]==(1||2)) Neighbour = true; if(GameField[modulo(x-1,MapSize)][modulo(y+1,MapSize)]==(1||2)) // po lewej Neighbour = true; if(GameField[modulo(x-1,MapSize)][y]==(1||2)) Neighbour = true; if(GameField[modulo(x-1,MapSize)][modulo(y-1,MapSize)]==(1||2)) Neighbour = true; return Neighbour; } </code></pre> <p>It's supposed to check if there are any neighbouring data in the container. I calculate the values manualy and using the debugger, and in each case the program acts as if there is no data in requested location, while it must there for it is present in the map. Any info will be appreciated.</p>

    1. CO`1||2` is not doing what you think it is doing. Also you would be better off with a 1D array. Index it like this: `myArray[(y)*width+(x)]`

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.
