bnahir	Posted - 09/14/2006 : 4:09:21 PM Origin Version (Select Help-->About Origin): 7.5 Operating System: Windows XP I have a hopefully easy question about vectors, datasets, and columns. I want to manipulate the data from a column in a worksheet without changing the original data. Currently, the only way I know to do this is to attach the column to a dataset then set a vector equal to the dataset. While this works just fine, it seems to be a waste of memory. So my question is whether it is possible to directly extract the data from a column and store it in a vector or if this intermediate step is absolutely necessary. Thanks, Ben

If the vector is defined in either way, the changes the vector will affect the column in the worksheet. 1. Worksheet wks=Project.ActiveLayer(); Column col(wks, 1); vector v(col); 2. Worksheet wks=Project.ActiveLayer(); Dataset dsB(wks,1); vector vB( dsB, FALSE ); // Copy Dataset dsD to vector vD removing missing values Deanna OriginLab GZ Office
