Increasing the number of PDF files that can be opened in a project
Description: By default, the number of PDF files that can be opened in a project is limited to about 7.500. When you try to link more files, the application might crash. This article describes how you can increase the number of files that can be opened.
Cause: Every PDF file that is opened requires a handle to a GDI object. By default, the number GDI objects per process is limited by Windows to about 10.000. Since there are also GDI handles necessary for other tasks, the number that is availabe for opening PDF files is around 7.500.

In Windows 10, there is a theoretical limit of 65,536 GDI handles per session. However, the maximum number of GDI handles that can be opened per session is usually lower, since it is affected by available memory. In Windows 2000 there is a limit of 16,384 GDI handles per session.

There is also a default per-process limit of GDI handles. This is the setting that limits the number of PDF files that can be opened per project. To change this limit, set the following registry value:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\GDIProcessHandleQuota

In Windows 10, this value can be set to a number between 256 and 65,536. In Windows 2000 this value can be set to a number between 256 and 16,384.

NOTE: After changing this setting, you have to Restart your computer.

Recommended IP addresses for FlexVision and HP2 Printer
Description: When you connect a FlexVision controller box, barcode readers, or the Specialty HP2 printer to the network and FlexMail or FlexStream, you are basically free to choose the IP address. However, for a stable and reliable connection we recommend you use a Class C IP adress.

Class C networks use a default subnet mask of and have 192-223 as their first octet. The address is a class C address. Its first octet is 192, which is between 192 and 223, inclusive.

For FlexVision we recommend you use:

  • Controller:
  • Camera 1:
  • Camera 2:
  • Camera 3:

For the Specialty HP2 printer we recommend you use:

  • Head 1:
  • Head 2:
  • Head 3:
  • Head 4:

For all of the above recommended IP addresses use Submask
