If you are working in a web project in Visual Studio.Net, the Add New Item dialog does not include an ASP file type. However, VS.Net does understand the file type. Click on the File | New menu, then choose the Script category. Active Server Page is the first template listed. With help from an article by Chris Sells, I created the procedure to make the ASP template available to Blank and Empty Web Solutions. These procedures assume that you installed VS.Net to the default location of C:\Program Files\Microsoft Visual Studio .NET\. If you didn't, then adjust the paths accordingly. All of the files mentioned are plain text. Make backup copies first!

Blank Solution
1.) Copy the file asppage.asp from [InstallDir]\Common7\IDE\NewScriptItems to [InstallDir]\Common7\IDE\NewFileItems.
2.) Open [InstallDir]\Common7\IDE\NewScriptItems\NewScriptItems.vsdir.
3.) Select the line containing asppage.asp
4.) Paste the line into file [InstallDir]\Common7\IDE\NewScriptItems\NewFileItems.vsdir

Empty Web Solution
1.) Create a file name ActiveServerPage.vsz in [InstallDir]\Vb7\VBProjectItems
2.) Enter the following:
      VSWIZARD 6.0
      Wizard=VsWizard.VsWizardEngine
      Param="WIZARD_NAME = ActiveServerPage"
      Param="WIZARD_UI = FALSE"
      Param="PROJECT_TYPE = VBPROJ"
3.) Open the file [InstallDir]\Vb7\VBProjectItems\Web Project Items\WebProjectItems.vsdir
4.) Add the following line. (Refer to the VS.Net documentation about VSDir files for an explanation of the values.)
      ..\ActiveServerPage.vsz|{164B10B9-B200-11D0-8C61-00A0C91E29D5}|ASP Page|1|Active Server Page|{164B10B9-B200-11D0-8C61-00A0C91E29D5}|4520| |ASPPage.asp
5.) Open the file [InstallDir]\Vb7\VBProjectItems\Web Project Items\Web\WebWebProjectItems.vsdir
6.) Add the following line. (Refer to the VS.Net documentation about VSDir files for an explanation of the values.)
      ..\..\ActiveServerPage.vsz|{164B10B9-B200-11D0-8C61-00A0C91E29D5}|ASP Page|1|Active Server Page|{164B10B9-B200-11D0-8C61-00A0C91E29D5}|4520| |ASPPage.asp
