On application start, the visual studio provides us one default view tab.

I want to prevent this tab being created..

In your main app file, find "InitInstance".
There, find a place where it says somomething like:

C#

CMultiDocTemplate* pDocTemplate;
    pDocTemplate = new CMultiDocTemplate(IDR_MyTYPE,
        RUNTIME_CLASS(CMyDoc),
        RUNTIME_CLASS(CChildFrame), // custom MDI child frame
        RUNTIME_CLASS(CMyView));
    if (!pDocTemplate)
        return FALSE;
    AddDocTemplate(pDocTemplate);

Comment that not to create a default tab.

Hope it helps.
