CheckFolderVersion

[jdrescher]

Hello!!

We have the following problem: We build a patch with VP3 which doesn´t work, because the function CheckFolderVersion(...) always returns 0. If we load the project with VP2, everything works.
Then we created a new project and the same problem appeared.
Here is a part of our code we use:


if not g_InstalledVersion then
local MainKey = HKEY_LOCAL_MACHINE;
local SubKey = SessionVar.Expand("Software\\Test");
local ValueName = "HomeDirectory";
local FolderPath = Registry.GetValue(MainKey, SubKey, ValueName);

FolderPath = String.Concat(FolderPath, "\\bin");

g_InstalledVersion = VisualPatch.CheckFolderVersion("%AppFolder%", FolderPath);
if g_InstalledVersion then
SessionVar.Set("%AppFolder%", FolderPath);
end
end


Has this function (CheckFolderVersion) changed from VP2 to VP3 and how does it exactly work internal?

Has this function (CheckFolderVersion) changed from VP2 to VP3 and how does it exactly work internal?It now supports key files in subfolders automatically.

Try removing this line:

FolderPath = String.Concat(FolderPath, "\\bin");

You might also want to add some Debug.Print() or Dialog.Message() calls in there to see what those variables contain at run time.
