2.2.3.9.9 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.

}

Remark

Copies a specified range from a worksheet to a matrix dynamically resizing the matrix as needed.
