Using PDF Creator Pilot on ASP.NET Web Pages without Visual Studio

To do work with ASP.NET, we must perform three steps:

  1. Create an Interop-wrapper
  2. Copy the wrapper into a specific folder
  3. Attach the namespace libraries to the application

To create the Interop-wrapper of PDF Creator Pilot (i.e. a wrapper that would make it possible to call unmanaged COM-object code of the library from the managed code of an ASP.NET application), we should use one of the standard utilities from the .NET SDK – TlbImp.exe (C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\TlbImp.exe)


TlbImp.exe PDFCreatorPilot3.dll /out:Interop.PDFCreatorPilot3Lib.dll

Then we need to copy the wrapper into the “bin” subfolder of the web-application root folder. (If that folder does not yet exist, we will have to create it.)


If our web-application is located in “C:\Inetpub\wwwroot\MyApp”, then we should put the wrapper into “C:\Inetpub\wwwroot\MyApp\bin”.

To attach the web-application to the namespace library, we should append the following line to the “.aspx”-file:

<%@ Import Namespace="Interop.PDFCreatorPilot3Lib.dll" %>

After that, a COM-object of PDF Creator Pilot may be used from ASP.NET.


<%@ Import Namespace="System" %>
<!-- other import directives are here -->
<%@ Import Namespace="Interop.PDFCreatorPilot3Lib.dll" %>
  <SCRIPT language="C#" runat="server">
    void ButtonPerform_Click(object sender, System.EventArgs e)
      PDFDocument3Class pdf = new PDFDocument3Class();
      pdf.StartEngine("demo@demo", "demo");
      pdf.AutoCreateURL = true;
      // set other options if needed
      // do something
  <!-- here page content goes -->
  <FORM runat="server">
    <INPUT type="button" id="ButtonPerform" value="Click Me"
      OnServerClick="ButtonPerform_Click" runat="server" />
    <!-- or another vaiant -->
    <asp:Button id="ButtonPerform1" Text="Click Me"
      OnClick="ButtonPerform_Click" runat="server" />
