Create a Custom MessageBox - C#, Visual Basic (VB.NET) & WinForms / Modern Flat UI

Hi, today I will show you how to create a Custom MessageBox with Windows Forms, CSharp & VB (Visual Basic .NET). Basically this custom message box does everything a standard MessageBox does, for example set the text, a title, buttons, icon, default button and returns the value selected by the user in the dialog box (DialogResult).

In order to be able to customize the message box title bar, you set the form border style to none, then simple panel on the form imitates the form title bar.
That way you can easily adjust the "title bar" back color by changing the panel back color and that is clear.
But, if I am correct, I don't see that you have provided the code in order to allow user to grab the form by title bar area and move it around.
The easiest way to do it is to override the DefWndPro method.

Hello, can you make wet nod32 antivirus UI?

[RafaelZelayax]

Great code but give me problems with windows 10 and resolution of 300% (recommended by default) so I comment the = new Size(550, 0); because is giving me messages with just the half of the space avaible and after that in the method SetIcon(... I change the way to add the image this.pictureBoxIcon.Image = Properties.Resources.error; for this one = Properties.Resources.error; for each type of message, because I need to use this line after the switch of icons = ImageLayout.Zoom; all this because of the size of the icon (is too small with 300% resolution). Hope this help someone. Cheers

Was expecting some code that uses windows resources to construct the wpf window with msg box. But unfortunately it's just a plain old windows forms app mocking modern ui.
