ShowUI Function in Begin Block Does Not Run in PowerShell Console


When a ShowUI function is run from the begin block in a function in the PowerShell console, it will not load. The console is in STA mode with no modules other than ShowUI.

This does work properly in the ISE.

In my script, I'm creating a tab item with a header property. It appears that it cannot bind to that property.

From the pipeline trace - PipelineProcessor Information: 0 : Exception System.Management.Automation.ParameterBindingException: A parameter cannot be found that matches parameter name 'Header'.

In further testing, it seems to be general problems with using the tabcontrol and tabitems in the powershell.exe host.

I believe you're using PowerTab which has a conflicting New-TabItem function (which, by virtue of being a function, overrides our cmdlet, even though you load ShowUI 2nd). In ShowUI 1.2, if you use the alias "TabItem" it will resolve correctly, but you can also make sure by using this syntax: ShowUI\New-TabItem

Thanks Joel. That worked.
