Hi

Having cache problem in ISAPI environment.

I have read:

if TIWCGPicture.UserCache = True, it will created session image files in userimgcache subfolder, that are always created one time per session, and are deleted when and if the web application exits normally, all the subfolder userimgcache is deleted in these circumstances.

As you can see in the image it tries to create a file in a session subfolder. We made sure the folders are writable.
Any idea what can go wrong here?

My development is with a standalone exe, I don't see any Session based folder being created, but all works fine!

My Code with the Image causing the problem:

Code: Select all

     if (UserSession.cdsDossier.FieldByName('GESLACHT_ID').AsInteger) = 1 then
        LImage := 'iconm.jpg'
      else
      if (UserSession.cdsDossier.FieldByName('GESLACHT_ID').AsInteger) = 2 then
        LImage := 'iconv.jpg'
      else
        LImage := 'icon.jpg';

      if (FileExists(FFolder + IntToStr(UserSession.SelectedTrajectClient_ID) + '.jpg')) then
      begin
        FS := TMemoryStream.Create;
        FS.LoadFromFile(FFolder + IntToStr(UserSession.SelectedTrajectClient_ID) + '.jpg');
        IWCGJQImage2.Picture.LoadFromStream(FS);
        FS.Free;
      end
      else
      if (FileExists(IncludeTrailingPathDelimiter(IWServerCOntroller.ContentPath) + LImage)) then
      begin
        FS := TMemoryStream.Create;
        FS.LoadFromFile(IncludeTrailingPathDelimiter(IWServerCOntroller.ContentPath) + LImage);
        IWCGJQImage2.Picture.LoadFromStream(FS);
        FS.Free;
      end;

Hi

Damn systemmanager, asked 5 times he was sure the dll has write access he said yes, but is was not! So now it can write.

Still question why userimgcache not filled in my development environment?

Hi Eric,

The path for image cache files is composed of :

Code: Select all

ServerController.ContentPath + 'userimgcache' + WebApp.AppID

If you can't see the folder, thats means, the app doesn't have rights to write.

Best Regards.
