How to move a server license to a new server”

The following article describes how to move a server license to a new server.

What is the difference between the Standard and the Professional edition?

In addition the Standard edition, the Professional edition allows you to fill in fields, interact with annotations, add new content, delete, add and move pages and save changes.

What is the difference between an upgrade license and a regular license?

An upgrade license can only be activated if you already own the last version of the product. Thus if you already own a PDFReaderControls.NET 1.1 Professional Client Application License, you can purchase the PDFControls.NET Professional Client Application License (Upgrade).

Do I need a license for my developers

No, you can continue to use the unlicensed software for the development environment. The only difference with the licensed software is that unlicensed software contains a watermark on the output.

I am now using PDFReaderControls.NET 1.1 and want to upgrade to 2.0. Is 2.0 fully backwards compatible?

No, in order to introduce new functionality, we had to break backwards compatibility. The evaluation download includes a developer guide which has a chapter that discusses upgrading in detail.

Is PDFControls.NET Vista, Windows 7 and Windows Server 2008 compliant?

Yes, fully.

Can PDFControls.NET be used on a shared web server where I am not allowed to do any machine level configuration?

Yes, PDFControls.NET is verifiable (or 100% managed). This means that to use PDFControls.NET in your ASP.NET application, you only have to copy the assembly to the bin folder of your virtual folder.

How to speed up print jobs?

In general, the speed of a print job is related to the graphical complexity of a PDF document. In some cases, this is inherent to the document, and there is little than can be done about it. In other cases however, slow printing may be relatively easy to improve. This article describes how to improve print speed.

Is it possible to create high resolution PDF's, such as 300 or even 600 dpi?

All text and curves in a PDF are vector-based so resolution does not apply to these types of graphics. Resolution does apply to embedded images though. The effective resolution of an embedded image follows directly from its physical width and height (these are set by the client application) and the resolution of the image itself (this is a given). For example, say you have a 300 x 400 bitmap and you add this to a PDF using the ImageShape. If you then set the width and height of this image to 75 x 100 points, then the effective resolution of the image is ( 300 / 75 ) * 72 = 288 DPI.

I open the type reference (.chm) but each page seems to be missing?

By default XP SP2 does not trust a .chm that originates from the internet. Right-click the help file, select 'Properties' and click the 'Unblock' button on the 'General' tab.
