If the parameter expects a By Reference System.Object, is it possible to pass a variant of Type.Missing?
For example: Is it possible to use Type.Missing with ShDocVw's Navigate method? axWebBrowser1.Navigate("http://www.google.com/", Type.Missing, Type.Missing, Type.Missing, Type.Missing); Richard > -----Original Message----- > From: dotnet discussion [mailto:[EMAIL PROTECTED]]On Behalf Of > Adam Nathan > Sent: 07 May 2002 02:26 > To: [EMAIL PROTECTED] > Subject: Re: [DOTNET] CSharp and optional parameters > > > Note that if the optional parameters are System.Objects (VARIANTs), or > if you're willing to do a late-bound call, you can just pass > Type.Missing for each optional parameter instead of figuring out and > passing the default value for each one. > > -----Original Message----- > From: Tom Archer [mailto:[EMAIL PROTECTED]] > Sent: Sunday, May 05, 2002 6:07 PM > To: [EMAIL PROTECTED] > Subject: Re: [DOTNET] CSharp and optional parameters > > That's correct.
