OverviewExamples

Example 1

-- Define a global variable that will indicate the name

-- of the installed version on the user's system. A nil value

-- indicates that an installed version has not been found.

g_InstalledVersion = nil;

 

-- Location method: Current folder

-- Check whether the software is installed in the folder

-- that the patch was run from.

if not g_InstalledVersion then

   g_InstalledVersion = VisualPatch.CheckFolderVersion("%AppFolder%", _SourceFolder);

   if g_InstalledVersion then

       SessionVar.Set("%AppFolder%", _SourceFolder);

   end

end

Checks to see if the folder where the patch is running from (denoted by the global variable _SourceFolder) is found to be the application folder being searched for.

Example 2

-- Location method: Registry key

-- Read a folder path from the Registry.

 

if not g_InstalledVersion then

   local MainKey = HKEY_CURRENT_USER;

   local SubKey = SessionVar.Expand("Software\\Your Company\\Your Product");

   local ValueName = "InstallFolder";

   local FolderPath = Registry.GetValue(MainKey, SubKey, ValueName);

   g_InstalledVersion = VisualPatch.CheckFolderVersion("%AppFolder%", FolderPath);

   if g_InstalledVersion then

       SessionVar.Set("%AppFolder%", FolderPath);

   end

end

Checks to see if the folder path read from a Registry key is found to be the application folder being searched for.
