第2课 建一个99乘法表

这部分演示如何把数据放入网格内。

第1步 添加网格行和列的标题

在 MyCug 类的 OnSetup() 函数中添加编辑为如下代码：

C++ Code

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

void MyCug::OnSetup() { //****** Declare all variables CString heading; int num_rows, num_cols, index; //****** Set the Rows and Columns SetNumberCols(10); SetNumberRows(10); //****** Get the number of rows and columns num_rows = GetNumberRows(); num_cols = GetNumberCols(); //******* Add the Row Heading to the grid for (index = 0; index < num_rows; index++) { heading.Format("%d", index + 1); QuickSetText(-1, index, heading); } //****** Add the Column Heading to the grid for (index = 0; index < num_cols; index++) { heading.Format("%d", index + 1); QuickSetText(index, -1, heading); } }

第2步 把乘法表置入网格中

在 MyCug 类的 OnSetup() 函数中添加编辑为如下代码：

C++ Code

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38

void MyCug::OnSetup() { //****** Declare all variables CString heading, number; int num_rows, num_cols, index; //****** Set the Rows and Columns SetNumberCols(10); SetNumberRows(10) ; //****** Get the number of rows and columns num_rows = GetNumberRows(); num_cols = GetNumberCols(); //******* Add Row Heading to the grid for (index = 0; index < num_rows; index++) { heading.Format("%d", index + 1); QuickSetText(-1, index, heading); } //****** Add the Column Heading to the grid for (index = 0; index < num_cols; index++) { heading.Format("%d", index + 1); QuickSetText(index, -1, heading); } //***** Add the Multiplication table to the grid for (int x = 0; x < num_cols; x++) { for(int z = 0; z < num_rows; z++) { number.Format("%d", ((x + 1) * (z + 1))); QuickSetText(x, z, number); } } }
