PRB: Design, Source, and Quick View Tabs Are Unavailable

When you edit Active Server Pages (ASP) or an HTML page in Visual InterDev 6.0 or later, the following tabs are unavailable:

• Design
• Source
• Quick View

In addition to the missing tabs, you may notice that all of the options on the toolbars are grayed-out. Server-side code may be highlighted in yellow.

There are two reasons for this behavior:

1. The default editor for the page is set to open in some other registered editor.
2. The TriEdit.dll is not correctly registered.

To resolve this problem, install Visual Studio 6.0 Service Pack 3.

Another option is to use the following steps to set the default back to the HTML editor that ships with Visual InterDev 6.0:

1. Right-click the HTML or ASP file.
2. Select Open With from the shortcut menu.
3. Click on the HTML Editor and select Set Default.

To re-register the TriEdit.dll, run the following command: Where <path> is the fully qualified path to the TriEdit.dll

By default, the TriEdit.dll is located in the following location: NOTE: If problems persist after performing the above steps, see Q-article Q270656 in References section.

In general, Visual InterDev 6.0 is not compatible with the Internet Explorer 5.0 Beta. Internet Explorer 5.0 Beta is not supported with Visual InterDev due to these and other problems. It is recommended that it not be installed on any workstation that is used for production development using Visual InterDev 6.0. Once installed, the beta is very difficult to remove completely, often times resulting in a complete reformat of the hard disk and reinstallation of the operating system for Visual InterDev 6.0 to work.

A specific upgrade of Visual InterDev is planned to fully support and take advantage of the added functionality of Internet Explorer 5.0.
