WinForms FAQ - In IE

These articles should give you some introduction to hosting WinForms Controls in IE:

Using Windows Forms Controls in Internet Explorer

Host Secure, Lightweight Client-Side Controls in Microsoft Internet Explorer

1) Cannot override methods like WndProc, ProcessCmdKey, etc in a derived Control. The class ref for a particular property will let you know about the permission requirements.

2) Cannot call Control.Parent.

3) Cannot call Control.Focus() method.

The issues listed here are pertaining to code running in IE in the default Internet Zone.

1) You cannot view Controls inside IE using the 1.0 framework (when running with the permissions in the default Internet Zone). This is however possible with the 1.1 (Everett) framework.

2) Use only one . in the assembly file name and ‘Assembly Name’(in Project Properties Dialog). For example, ‘Syncfusion.Shared.dll’ is an invalid dll name, but ‘Shared.dll’ is valid.

3) Signed assemblies couldn’t be loaded.

You cannot use a WinForms Control directly in IE, you will have to instead derive from it and then use the derived instance from a custom assembly.

The following command line will do the trick:

gacutil /cdl
