$fverp function

$fverp(path)

The $fverp function returns the product version of the file specified by path, as 4 decimal numbers separated by periods: a.b.c.d, from most to least significant. If path does not refer to a file, if the file does not exist, or if the file does not have a VERSIONINFO resource, the result is 0.0.0.0.

You can use the resulting version as-is, or compare it against another version with the $vercmp function. To retrieve the file's product version and compare it against a given version in a single operation, you can use the $fverpcmp function. To retrieve the file's file version instead of its product version, use the $fverf function.

Parameters

All parameters may contain symbolic references; these are resolved before the function is applied. See Examples below.

path

File path of the file whose product version must be retrieved.

Examples

Here are some usage examples for this function:

<$fverp(<WindowsFolder>\Notepad.exe)>

Returns the Notepad.exe product version, for example 5.1.2600.2180 (for Windows XP).

<$vercmp(<$fverp(<WindowsFolder>\Notepad.exe)>, 5)>

Compares the Notepad.exe product version to 5.0.0.0 and returns a value < 0, 0, or > 0 depending on the result. You can achieve the same effect with less typing by using <$fverpcmp(<WindowsFolder>\Notepad.exe, 5)>.

<$fverp(<#Tin_alias>)>

Returns the product version of the Tin.exe executable, assuming that Tin_alias is the file alias for that file.
