Hello Peter,I had this problem also, working on German and English systems. I solved this problem under LabVIEW 4.0 ( I do not know if there is a new option under 5.1 to query if , or .).I am made a VI that Converts a number to a floating point string, then checked the string if it had a "." or "," in it.I would send you the VI but I do not had it anymore (by former employer).-Paul AugartOCE Printing Systems GmbHPaul.Augart@OPS.de"Peter Jansson, Teracom Malmoe" wrote:Hi all!Is there an way to query the system wether it uses , or . as decimalpoint(under CONTROL PANEL, NATIONAL SETTINGS)?Thank´s!--/Peter Jansson,Teracom Systemservice Malmoe Swedenhttp://www.teracom.se
