The Sample Test App
A test app, KN-UDI Test, provides a visual log. Sample screen captures used to verify the status of loading app support data in the tutorial:
Code
A common unified desktop app installer class, called clsUDI, is provided. When an app starts, the first thing it should do is create the class, test if the app's support data exists, and create the app support folders before loading the data:
Dim udi As New lsmUDI.clsUDI(kUDI_strCompany, kUDI_strAppName)
Dim intResult As Integer
If (udi.doesAppSupportFolderExist > 0) Then
gintAppSupportFoldersCreated = udi.createAppSupportFolder
If (gintAppSupportFoldersCreated > 0) Then
If (udi.loadFile("ReadMe.txt", "") = 0) Then
intResult = udi.loadFolder("Logs", "Application Support")
Documentation
The documentation to use clsUDI has a unique 4-page newspaper format:
