How it works
The viewer requires two files to work: Viewer7.exe (~240k) and Vectors1.fnt (6k).  Viewer7.exe is the viewer program and can be launched by double-clicking on it.  Vectors1.fnt is a support file (the onscreen fonts). It must be in the same folder as Viewer7.exe. If vectors1.fnt is not in the folder with Viewer7.exe, Viewer7 will not open.

When Viewer7 opens, it looks in the folder (the same folder that Viewer7 is in) for a chart. If it finds a chart, it opens it. If there are multiple charts in the folder, Viewer7 opens the first chart it finds.

Sending Charts via email In order for the recipient to view your chart, you will need to send 3 files. Viewer7.exe, vectors1.fnt and your chart file (you can include several chart files). You may need to zip the files together since many email programs won’t accept executable files (like Viewer7.exe) as attachments.  Instruct the recipient to copy all the files into one folder and double-click on Viewer7 to open the chart. If you and the recipient both use Winzip, instruct the recipient to double-click on the zip file, select “Checkout” to load the files into a temporary folder, then double-click on Viewer7.exe to launch the viewer and the chart.

Unzip/copy all three files (Viewer7.exe, vectors1.fnt and yourchart.gc7) into one folder and double-click on Viewer7.exe to launch the viewer. The Viewer will find and open the chart.

Distributing Charts on a CD Distributing charts on a CD (or floppy disk or flash media) gives you the opportunity to set up the folder structure. This means that you can set up the map(s) to be launched from relative links established in other applications like Word or Powerpoint. Simply place a copy of Viewer7, vectors1.fnt and your chart in a folder. For each chart you want to launch, place all three files in their own folder. For example, if you want to launch 3 different charts, create three folders. In each folder, place your chart, Viewer7 and vectors1.fnt. Set links to Viewer7.exe in each folder to launch the corresponding charts.

If you are sending multiple charts, you can specify which chart Viewer7 opens.

Specifying a Chart
When Viewer7 is closed, it creates/updates a text file (graham7.ini) with the name of the chart file that was being viewed (Note: if the software is launched from read only media, like a CD, it can’t create or update the ini file). The next time Viewer7 is opened it will open the chart specified in graham7.ini.  If you are sending multiple charts, you can specify the chart that you would like opened by updating graham.ini and including it with Viewer7.  If you would always like the same chart opened first, specify that chart in graham7.ini and set the read/write attribute for graham.ini to read only. (Right click on the chart in Windows Explorer, select Properties and check the Read-only checkbox in the properties window.)

Distributing Multiple Charts Whenever a chart is opened from the Viewer7 File menu, Viewer7 updates a text file (gflist.xxx) with the file name (Once again, as long as the software is not launched from read only media). If the file doesn’t exist, Viewer7 creates it. This file holds up to ten chart names that show up on the file menu. If you are distributing charts on a CD, you can create and edit this file (before you put it on the CD) to make it available to the recipient.
