Windows 95, 98, and Me Users:
There is a known issue with GDI system resource management when using
ImageSalsa with these operating systems. I found a great explanation
In particular, these operating systems
limit the amount of graphics memory shared by all applications and
utilities that are running -- independent of the amount of system RAM.
Because ImageSalsa uses so much graphics
through its real-time image processing with various layers and effects,
the OS can be quickly become overwhelmed and generate the infamous "Out of
Memory" error -- usually in ImageSalsa's CreatePictureBox procedure.
There is no easy solution. Some
users have been able to use simple canvases with few different layers
without any problems. Some have also had better luck with version
1.8 of ImageSalsa:
setup.exe Because it is shared among all applications
running in the OS, different users will have experience different results.
The only certain workaround to this issue
is to move to an NT-based OS (NT, 2000, XP, Vista). These operating
systems scale GDI resources with the amount of available system memory and
have worked with ImageSalsa for months on end without any memory issues.

Virus scanners: Many virus scanners may assume that scripts running
under ImageSalsa (for example, those that access files) are malicious.
This is unfortunate since scripting can also do so many cool things.
Depending on which virus scanning software you use, you may be able to disable scripting if you know that you will not be running malicious
scripts from the internet. Many virus scanners will let you run the
scripts after you tell them they are O.K., but you have to do this each
time ImageSalsa starts.
Uses the NOAA monthly reports generated

Also, must select "Script Enable" for each text line that uses these tags

Contains a lot of code. Part of which includes my first attempt to
pick the weather data from a NWS forecast message and then use that data
to change a forecast panel (see Demos).
This script reads a text file of comma-separated values and makes them available
as tags in the format <TAGxxx>, where xxx is 001, 002, ... The
comma-separated value file may come from anywhere, but the original intent
was to use Virtual Weather Station to convert a template file into values
not available in the data.csv file used for the built-in weather
This script reads a ini file of data values and makes them available
as tags in the format <INI,Section,Key>, where Section and Key are
the respective INI entries. The
INI file may come from anywhere, but the original purpose was to use the
curdata.lst file generated by the Weather Center software -- example
This very simple script will change the directory for a canvas' sequential

Here are some useful links I've found on writing VBScript code:

In particular, you will want to look for
certain keywords when searching for information on the scripting language:
- The scripting language is VBScript.
- When reading and writing files, you
will be using the File System Object.
- When executing other programs you will
be using the Windows Script Host Object Model.
- You will be writing programs that more
closely match the Windows Script Host -- often abbreviated as
Many VBScript books are written for web
programming. However, there exists a difference in the Object
Model. When running VBScript in a browser, there exists a set of
objects that make up the object model such as the web page, controls,
images, etc... These books spend a good amount of time teaching
users how to write program to interact with this object model. While
this is a good knowledge for web developers, ImageSalsa uses its own
object model that is described in the User's Guide. In addition, you
can interact with any registered COM object on your system or the Windows
Script Host object model.
These books are available from Amazon.com
and should help users to understand how to write scripts for the Scripting
or Weather Editions of ImageSalsa.

This book is a reference and will not
provide as many code examples as others. However, it will go into
great depth on the object models and VBScript language.

Both of these books are geared towards programmers writing code for the
Windows Script Host. This more closely resembles programming for
ImageSalsa and will present many of the object models and examples that you
would likely use.
