UiXml previewer problems

[generalloki]

UiXml previewer has some problems:

I collected them from the #15:

• Referenced images are not correctly loaded by UiXml previewer. Previewer doesn't like "embres:MenuSample.Resources.Icons.Small.Photo16.png"
• Local controls are not corretly loaded by UiXml previewer. Previewer doesn't like when they have own xml.
• App need to be compiled before UiXml previewer start to work.
• Window events are called UiXml previewer but in the strange maneer (not the same way as it is usually done by the application during normal start). This causes different exceptions.
• WebBrowser preview not working
• Errors in preview not easy to understand
• If uiXML is not valid - the previewer does not display anything.
• UiXML code completion should not display enumerations as tags.

Also preview of Menu or Toolbar shows Windows desktop

I have uploaded 0.9.620-beta and it has an updated uixml preview which works ok. https://github.com/alternetsoft/AlternetUI/releases

There are still some problems:

• We need to wait for some time when Visual Studio started before opening uixml or we have an exception.
• We need to build project before opening uixml
• Uixml from ControlsSampleDll and maybe other dlls are not opening, only uixml from exe projects are opened.
