Controlling print settings using Excel macro

Sorry, I solved that problem. The next issue is another compile error: type mismatch for this line of code:

 ReDim yDevModeData(nRet + 100) As Byte
      nRet = DocumentProperties(0, hPrinter, sPrinterName, _
                  VarPtr(yDevModeData(0)), 0, DM_OUT_BUFFER)

The section of code highlighted is VarPtr
