This site is for VB.NET related inquiries only.

The Form class has a ActiveMdiChild property (of type Form), so this also has a Controls collection.

accessing activemdichild in c++.net 205

I have created a browser in vb.net C# and Im now making one in c++.net
Ive used a Windows application type for c++ and I need to navigate the webbrowser on the activemdichild.
In vb.net i used

dim child as form1 = TryCast(form1,activemdichild)

and in c# I used

Form activeChildForm = this.ActiveMdiChild;

            if (activeChildForm != null)
            {
                WebBrowser activewebbrowser = (WebBrowser)activeChildForm.ActiveControl;
                if (activewebbrowser != null)
                    activewebbrowser.Navigate(toolStripComboBox1.Text);
            }

For c++ I tried

 Form^ activeChildForm = this->ActiveMdiChild;
                WebBrowser^ activewebbrowser = (WebBrowser^)activeChildForm->ActiveControl;
               activewebbrowser->Navigate(toolStripComboBox1->Text);

it doesnt give me any errors on compile time but when I run the application nothing happens, Im not able to navigate the activemdichild webbrowser
