Title: New page not available in designer mode
Post by: SOUS on May 12, 2018, 04:08:08 PM

 :-[
Sorry to have to ask this, but i'm struggling trying to add a third page into my project. I tried to find some hints in the forum, but found nothing helpful.
I'm a beginner with VB, (using Visual Studio 2017 community)
I am adding a windows form by right clicking on AdvancedHMI then choosing Class and whatever i do i can't get this new page available from a FormChange button, or even get it to open in designer mode.
What am i doing wrong... ?

You need to choose "Windows Form" instead of "Class", just like the attached picture shows.

Then you can also add the following code to it:

Code: [Select]

    '*******************************************************************************
    '* Stop polling when the form is not visible in order to reduce communications
    '* Copy this section of code to every new form created
    '*******************************************************************************
    Private NotFirstShow As Boolean

    Private Sub Form_VisibleChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.VisibleChanged
        '* Do not start comms on first show in case it was set to disable in design mode
        If NotFirstShow Then
            AdvancedHMIDrivers.Utilities.StopComsOnHidden(components, Me)
        Else
            NotFirstShow = True
        End If
    End Sub

The other way of creating a new form would be to copy existing form, like Page2.vb, and then paste it to AdvancedHMI project. The exact steps would be:

- right-click Page2.vb and then click Copy
- right-click AdvancedHMI project and then click Paste
- rename this newly created copy to whatever name you want
- right-click  this newly created copy and then click View Code
- replace Page2 with your new name in the following line: Public Class Page2

Thanks for the reply, but i've already tried this one, and whatever i choose in the next Windows does not seem to work.

Once you add a new form then close all the forms and re-open them.

If necessary, close the solution or Visual Studio and re-open it.

Archie suggested to build the project, in this post:

Nope, still do the same thing.

Nevertheless, i figured out i could just copy and paste the page2 and rename it page3...
I gaves me a couple of building errors, but from the output windows, i have been able to open the new page3 designer page in "code view" then rename Page2 to page3 into it, then it finally works...
Sounds weird, i guess something might be wrong with my Visual Studio settings...

Anyways, thanks for your time!

All the information posted in this topic should be sufficient to resolve the issue (which seems to be related to the Visual Studio installation on one's computer).
