ConvertPathToUNC
|
Procedure
|
Converts the named path to its universal naming convention (UNC) representation.
This function returns the full UNC (Universal Naming Convention) path for the given file system path. For example, assume that your F: drive is mapped to a shared network drive on your server named "dev". The UNC mapping for this would be \\dev\directoryname where directoryname is the name of the directory the drive is mapped to. If you specify a path and a file name and extension for the strFileName argument, the file name and extension are returned along with the UNC path.
If the path you pass is not a mapped network drive, this procedure calls the Windows API to get your computer name. This name becomes the root of the UNC path. For example, if your computer is named "MyComp", and your C drive has the label "MyC", the UNC path would be \\MyComp\MyC.
