Alignment Troubles with Panel1.Controls.Add(browser)

Postby vmars316 » Mon Oct 05, 2020 12:09 pm

Hello & Thanks;
Having Alignment Troubles with Panel1.Controls.Add(browser) .
And 3 controls in all .
When a webpage is displayed (skewed) about 50px below the top
and 20px to the right of where it should be .
How can I fix this ?
I have both a .vb & .cs version . Both have the same issue .
Below is Form1.vb followed by Form1.Design.vb .
Thanks for your Help...
Form1.vb

Code: Select all

Imports CefSharp.WinForms
Imports System.Windows.Forms

Public Class Form1
    Private WithEvents browser As ChromiumWebBrowser
    Public Sub New()
        ' This call is required by the designer.
        InitializeComponent()
        ' Add any initialization after the InitializeComponent() call.
    End Sub

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim setting As New CefSettings
        '        setting.RemoteDebuggingPort = 8088
        CefSharp.Cef.Initialize(setting)
        browser = New ChromiumWebBrowser("https://www.google.com/") With {
                .Dock = DockStyle.Fill
                }

You likely need to make your application DPI aware.

Thanks ,
Yes , because of eyesight issue , I run with DPI at 150% .
Code: Select all
Class SurroundingClass
    Private [Public] As [Private]
    Private Sub EnableHighDPISupport()
End Class

Public Class Form1
    Private WithEvents browser As ChromiumWebBrowser
    Public Sub New()
        ' This call is required by the designer.
        InitializeComponent()
        ' Add any initialization after the InitializeComponent() call.
    End Sub


Should I enable dpi or disable it .
I tried this: Private Public void EnableHighDPISupport()



But get these errors:

Severity Code Description Project File Line Suppression State
Error BC30026 'End Sub' expected. ChromeVB01 C:\Users\vmars\source\repos\ChromeVB01\Form1.vb 8 Active
Error BC30002 Type 'Private' is not defined. ChromeVB01 C:\Users\vmars\source\repos\ChromeVB01\Form1.vb 7 Active

How to proceed ? Thanks

Thanks;
I stuck recommended .xml into all CefSharp.WinForms.XML files .
That made an improvement , but still off :

But I can't expect kids (KidsSafeBrowser) to adjust 'display settings' if needed .
If I can't do it programatically , is there a way to use some sort of
scripting or .bat , etc. ?

Thanks

I just noticed that when I click on a Link
up pops a new window & all is aligned ,
except that no GO button and no Address txt box .

Is that a clue or just a popup ?
Thanks

Turns out
when I add the following in App.config.

Code: Select all
   <System.Windows.Forms.ApplicationConfigurationSection>
     <add key="DpiAwareness" value="PerMonitorV2" />
   </System.Windows.Forms.ApplicationConfigurationSection>

Everything works as expected.
Thanks for your Help...
