Can anyone have a look at my code, I don't quite follow what is the error about
private void InitializeComponent()
{
this.WebBrowserHost = new System.Windows.Forms.Integration.ElementHost();
this.SuspendLayout();
//
// WebBrowserHost
//
this.WebBrowserHost.Dock = System.Windows.Forms.DockStyle.Fill;
this.WebBrowserHost.Location = new System.Drawing.Point(0, 0);
this.WebBrowserHost.MinimumSize = new System.Drawing.Size(20, 20);
this.WebBrowserHost.Name = "WebBrowserHost";
this.WebBrowserHost.Size = new System.Drawing.Size(284, 262);
this.WebBrowserHost.TabIndex = 0;
//
// AuthorizationWindow
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(284, 262);
this.Controls.Add(this.WebBrowserHost);
this.Name = "AuthorizationWindow";
this.Text = "AuthorizationWindow";
this.ResumeLayout(false);
}
In my form I just have a WebBrowser control and I am having the error:
Cannot implicitly convert type
'System.Windows.Forms.Integration.ElementHost' to
'System.Windows.Forms.WebBrowser'
After Initialize I need ElementHost.Child like this
public AuthorizationWindow()
{
// This call is required by the designer.
InitializeComponent();
WebBrowser = new System.Windows.Controls.WebBrowser();
WebBrowserHost.Child = WebBrowser;
WebBrowser.Navigating += WebBrowser_Navigating;
WebBrowser.LoadCompleted += WebBrowser_LoadCompleted;
_authorization = new AuthorizationState();
}
Did you try changing the line
this.WebBrowserHost = new System.Windows.Forms.Integration.ElementHost();
to
this.WebBrowserHost = new System.Windows.Forms.WebBrowser();
?

I am writing a Chinese GUI program using Visual Studio.
I have already tested this character on Visual Studio 2008 and 2017.
This problem happen in both version.
The character I was using is 戶 (\u6236).
The Font size become smaller when it is in the Form like Label, TextBox, Button text.
However, the character's size does not change in the Title Bar, Status Bar or Menu bar.
Can someone explain why this happen?
Cannot post image yet so I put down a link here.
As you can see, only this character become smaller.

I believe the issue you are having is to do with the auto scaling that windows performs to ensure correct scale on different screen sizes.
Have a read of Automatic scaling in Windows Forms
It maybe relevant to what your experiencing.
I have a ImageList, with one item, in the TabControl:
private System.Windows.Forms.ImageList tabControlMain_ilMain;
this.TabControlMain.ImageList = this.tabControlMain_ilMain;
this.tabControlMain_ilMain.ImageStream = ((System.Windows.Forms.ImageListStreamer)(resources.GetObject("tabControlMain_ilMain.ImageStream")));
this.tabControlMain_ilMain.TransparentColor = System.Drawing.Color.Silver;
this.tabControlMain_ilMain.Images.SetKeyName(0, "");
and I am setting this image to a specific TabPage:
this.tabControlMain_tp17.ImageIndex = 0;
and I can see in the designer the image attached to the TabPage, but when I am running the application, I cannot see the image, it is just an empty space near the TabPage name.
Does anyone know what could be the problem ?
Thank you!
P.S. What I have seen is that, if I am not selecting the ImageIndex, the TabPage header is getting less length, so I guess the image is taking the space, but cannot see it at runtime.
So i did nothing different than you i think. But mine is working.
Maybe remove and readd the controls.

I am unable to add webbrowser control to panel in winapp,getting this error"Unable to get the window handle for the 'WebBrowser' control. Windowless ActiveX controls are not supported."i also tried to do it using STAthread like

uy.SetApartmentState(ApartmentState.STA);
uy.Start();

You can have a browser pre initialized and later use it in your threads.
I have this simple code:
private void buttonOpen_Click(object sender, EventArgs e)

if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
textBox2.Text = openFileDialog1.FileName;

When I run program form doesn't show and exit of debugging mode.
In output view writes:The program '[4244] openfiledialog.vshost.exe: Managed (v4.0.30319)' has exited with code 1073741855 (0x4000001f).

As a general rule I initialize and use my OpenFileDialog's within the event that is calling it. I can't think of a circumstance in which I would want it to be a property of my window. The first thing I would do is delete it as a property and initialize it in your event.
private void buttonOpen_Click(object sender, EventArgs e)
{
using (OpenFileDialog openFileDialog1 = new OpenFileDialog())
{
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
textBox2.Text = openFileDialog1.FileName;
}
}
}
You don't need to set the FileName property to anything because the dialog will do it for you.
The only thing I found on your error code was this (Program and debugger quit without indication of problem). Which in your current code I cannot find anything that would cause this. If you are accessing unmanaged code you may need to enable unmanaged code debugging.

I also have a habit that i delete program.cs and frmMain.Designer.cs because i dont need them in my program , Does that have anything to do with my problem ? Help Please!
In frmMain() you're calling InitializeComonent() (which is empty) instead of calling InitializeComponent(). Probably just a typo.
Your code is fine. Just a small typo
public frmMain()
{
// In your constructor change 'IntitializeComonent' to 'InitializeComponent'
IntitializeComonent();
}
