I am passing a filename as a parameter to a window containing a PDF viewer. When I pass the filename as \10.5.1.40\Users\Public\Documents\SCADA\DS-SD300H.pdf The leading \ gets stripped off and I get \10.5.1.40\Users\Public\Documents\SCADA\DS-SD300H.pdf How can I format this to get the full UNC for the filename? ---

In scripting you have to use two \ for every one because of being escaped. So do the following: \\10.5.1.40\Users\Public\Documents\SCADA\DS-SD300H.pdf ---
