How to zoom content with MailBrowserControl

Question

I've found a solution for WebBrowserControl but MailBrowserControl doesn't have method ExecWB. So please advise. Thanks

MailBrowserControl inherits WebBrowserControl so you can use ExecWB on WebBrowserControl you can use it on MailBrowserControl

dynamic activeXInstance = mailBrowser.ActiveXInstance;
activeXInstance.ExecWB(
    Exec.OLECMDID_OPTICAL_ZOOM, 
    ExecOpt.OLECMDEXECOPT_DONTPROMPTUSER, 
    150, 
    IntPtr.Zero);

public enum Exec
{
    OLECMDID_OPTICAL_ZOOM = 63
}

public enum ExecOpt 
{
    OLECMDEXECOPT_DODEFAULT = 0,
    OLECMDEXECOPT_PROMPTUSER = 1,
    OLECMDEXECOPT_DONTPROMPTUSER = 2,
    OLECMDEXECOPT_SHOWHELP = 3,
}
