Those are the localized keys for the text values that should be pulled from the localization. The text values are embedded within the MicroFour StrataFrame UI.dll. There are a couple of reasons why the might not be loading:
1) You aren't using the StrataFrameApplication.RunApplication() method to run your app... the localized XML files won't get registered.
2) Your MessageLocaleID is getting set to something that isn't supported (maybe your customer's computer is set to French (Canada) or someting (though it looks like French (Canada) is supported...).
3) For some reason the XML files are not being pulled from the DLL. If that's the case, then you can call:
MicroFour.StrataFrame.UI.Localization.RegistereEmbededXmlFile(System.Reflection.Assembly.Load("MicroFour StrataFrame UI, Version=1.6.0.0, Culture=neutral, PublicKeyToken=99fe9917f71608a7", "Messages_1033.XML")
Where the "1033" is replaced with the proper locale ID. This will force the localized values to be pulled from the XML and placed inside the dictionary that is used to store the localized values.
