Question

I have converted a working C# class that embeds xls files to windows forms application to vb.

I am getting the error:

“Overload resolution Failed because no accessible’Navigate’ accepts this number of arguments”

at the following line:

from:

this.WebBrowserExcel.Navigated+=new System.Windows.Forms.WebBrowserNavigatedEventHandler(this.OnWebBrowserExcelNavigated);

to:

Me.WebBrowserExcel.Navigate += New System.Windows.Forms.WebBrowserNavigatedEventHandler(AddressOf Me.OnWebBrowserExcelNavigated)

i have also tried:

Me.WebBrowserExcel.Navigate += New System.Windows.Forms.WebBrowserNavigatedEventHandler(Me.OnWebBrowserExcelNavigated)

but i get error:

Error 13 Delegate ‘System.Windows.Forms.WebBrowserNavigatedEventHandler’ requires an ‘AddressOf’ expression or lambda expression as the only argument to its constructor.

any ideas?

thanks in advance.

The direct translation of C#’s delegate += is AddHandler in VB:

AddHandler Me.WebBrowserExcel.Navigated, AddressOf Me.OnWebBrowserExcelNavigated

Alternatively, you could do it the VB.NET way and use WithEvents and the Handles Clause:

Function OnWebBrowserExcelNavigated(...) Handles WebBrowserExcel.Navigate
    ...
End Function
