Description

To check if the matrix object is a virtual matrix.

Syntax

BOOL IsVirtual(DataRange* pRange = NULL)

Parameters

pRange: [output]the pointer of XYZ data range in Worksheet.

Return

returns true if the matrix object is a virtual matrix, else false.

Examples

EX1

1. Copy the following data and paste into an empty Worksheet.

	5	10	15
1	10	4	4
2	15	8	12
3	30	6	10

2. Select the whole Worksheet and run the following command to create a virtual matrix named "vm1".

w2vm format:=xacross rowpos:=selrow1 colpos:=wkscol1 vmname:=vm1;

3. Run the following sample function.

int MatrixObject_IsVirtual_ex1()
{
        MatrixObject matObj;    
        matObj.Attach("vm1"); // attach to virtual matrix by name

        // matObj should be virtual matrix
        DataRange dr;
        if( matObj && matObj.IsVirtual(&dr) )
        {
                out_str("matObj is Virtual Matrix.");
                
                // convert range to tree and output
                Tree tr;
                dr.GetTree(tr, false);              
                out_tree(tr);
        }
        
        MatrixPage matPage;
        matPage.Create("Origin");
        MatrixLayer ml = matPage.Layers(0);
        MatrixObject matObj2 = ml.MatrixObjects(0);
        
        // matObj2 should not be virtual matrix
        if( matObj2 && !matObj2.IsVirtual() )
        {
                out_str("matObj2 is NOT Virtual Matrix.");
        }
        return 1;
}
