You are welcome.
1. That is correct. The My namespace for VB.NET neither built nor maintened by the Visual WebGui designer. The My namespace is basically for convenience shortcuts for things you can do in a different manner, but may take more code. If there is anything in the My namespace that you need and you don't know how to reach, feel free to add a new thread and ask for help. I did add a tracker entry though, for considering if the My namespace should be implemented in Visual WebGui. Please view it here and follow up on our progress.
2. When you want to work with static images in Visual WebGui, you should create a Resources folder in your project directory. In there, you should create Icons and Images folders for storing Icons and Images. These are the default locations, but they can be changed in web.config or Visual Studio Integrations within the General Tab. You should view the General tab to see the default locations. The ImageResourceHandle is a builtin gateway that will use Resources\Images folder and IconResourceHandle will use Resources\Icons.
2a. We are fully aware of that there is no Visual WebGui manual yet. We are working hard on documentation, especially for the new features added on the latest releases. As for our current documentation with have the Wiki our KB and last, but by far not the least we have two demo applications that demonstrate many of our controls and how to use them. The Companion Kit is installed with your Visual WebGui installation, but you can also find it online here. The Catalog sample application is installed if you install a "with sources" type of installation, but you can also download it seperately from our downloads page here.
3. I don't fully understand this question. Please clarify.
Hope this helps,
