using the VB TO VC Automation Code Converter (B2CSE utility from Microsoft),
this call to AutoWrap

AutoWrap(DISPATCH_METHOD, &rVal, wkbs1.pdispVal, L"CountA", 1, parm);

sometimes correctly returns the number of non blank values in a range, and
other times it seems to miss values which are in the range, returning 0,
instead
of the number of columns.

Any ideas?


for(int r=1;r<=initialrow;r++)
{

string thecol="";

int acol=25;
thecol=ColumnLetter(acol);

string newrow="";
newrow="A"+biaUtils::extractInt(r)+":"+thecol+biaU tils::extractInt(r);
