    <p>The expected input is : SET_MINE X Y, while X and Y have to be numbers between 0-19; when the user finishes inserting his data he is expected to write SET_DONE. I'm facing two problems here, which apparently happen due to the same reason: 1. when I insert : SET_MINE (and then press ENTER) or SET_MINE X (inserting only one number rather than two), the line "Insert failed: not enough parameters" is printed on the screen an infinite number of times! 2. The exact same thing happens when I insert numbers out of the range [0,19], e.g: SET_MINE 56 7.Here I'm expecting to see this line on the screen "Insert failed: illegal row/col", but instead I get this one: "Insert failed: not enough parameters" printed an infinite number of times.</p> <p>Here is my code:</p> <pre><code>int main() { int game_board[FIELD_ROWS][FIELD_COLS]={0}; char szLine[MAX_LINE_SIZE]; char* delimiters = " \t\n"; char* pszCommand; char* pszCol; char* pszRow; BOOL gameContinue= TRUE; MINE* pHead = NULL; POSITION pos; int stepDirection; int row=0; int col=0; int old_row=row, old_col=col, mine=0; fgets(szLine,MAX_LINE_SIZE,stdin); // get line from standard input while (strncmp(szLine,"SET_DONE",8) != 0) { pszCommand = strtok(szLine, delimiters); if (NULL == pszCommand ) { continue; } if (0 == strcmp(pszCommand, "SET_MINE")) { pszRow = strtok(NULL, delimiters); pszCol = strtok(NULL, delimiters); if (NULL == pszCol || NULL == pszRow) { fprintf(stderr, "Insert failed: not enough parameters\n"); continue; } row = atoi(pszRow); col = atoi(pszCol); if (row &lt;0 || row &gt;= FIELD_ROWS || col &lt; 0 || col &gt;= FIELD_COLS) { fprintf(stderr, "Insert failed: illegal row/col \n"); continue; } game_board[row][col]=-1; // a mine is inserted to this place } fgets(szLine,MAX_LINE_SIZE,stdin); // get line from standard input } </code></pre> <p>Any ideas?!</p>

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.
