matrixbase::CopyFromWks
CopyFromWks
Description
Copies a specified range from a worksheet to a matrix.
Syntax
BOOL CopyFromWks( Worksheet & wksSource, int c1 = 0, int c2 = -1, int r1 = 0, int r2 = -1, DWORD dwCntrl = 0 )
Parameters
- wksSource
- [input] Source worksheet from which data is copied
- c1
- [input] Begining column index, default is 0 (0 based offset)
- c2
- [input] Ending column index, (inclusive) default -1 is GetNumCols -1 (0 based offset)
- r1
- [input] Begining row index, default is 0 (0 based offset)
- r2
- [input] Ending row index, (inclusive) default -1 is GetNumRows -1 (0 based offset)
- dwCntrl
- [input] Options defined in OC_Const.h : MCFW_CHECK_IGNORE_HIDDEN_ROW, etc.
Return
Returns TRUE on successful exit and FALSE on failure.

else
printf(" %s has been copied into %s(Size=%dx%d).\n",
wksName,Mat3.GetName(),Mat3.GetNumRows(),Mat3.GetNumCols());
// Result matrix:
// {2.5}
// {3.5}
}
Remark
Copies a specified range from a worksheet to a matrix dynamically resizing the matrix as needed.
