If you use Windows for your server, then REBOL/View can be used with server scripts (such as in CGI) to dynamically generate graphics. This is easly done by creating layouts then converting them to images: out: layout [ image %picture.jpg text "This is a picture" ] img: to-image out save/png %image.png img Note that only PNG output is currently available, but GIF output will be added in next release (because the patent has finally expired.) We also want to add JPEG output.

To do this correctly, you need to use the "functional" form of save: fname = 'foobar'; save(fname, 'variable'); In fact, it is true in general that the following two lines are equivalent: command str1 str2 str3 command('str1', 'str2', 'str3') This allows one replace any or all of the parameters with dynamically generated strings. This is also useful in commands like PRINT, LOAD, CLEAR, etc.

increasing number of our projects are dynamically generated websites, and we have several proven and non-intrusive workarounds for this.

The following is a shell script that flies a missile against a bogie that's tooling along on a fixed course. The user enters azimuth and elevation from a form and calls the CGI script. If you don't know how to call a CGI script from a form, there's an introduction to the topic at NCSA. #!/bin/sh fly_the_missile $WWW_azimuth $WWW_elevation > missile$$.tmp turn_it_into_vrml <missile$$.tmp >missile$$.

When issuing a map request that contains only a legend spec with no drawable map data (not specifying any basemap/themes/features), MapViewer will generate a map image that contains only the map legend. You can then get the URL of this legend image and show the legend somewhere in your web application external to the map images generated. This is more efficient than embedding a legend in every generated map.

With each Wizard you may generate exactly one website. If you want to create another website with the same Wizard you have to buy another license first.

How to generate HTML table accoding to XML data by using XSLT? An example with format-number() and recursion.

Answer : Sometimes. Again please bear in mind how little time I have to work on such projects so I cannot accept many of these requests right now. But feel free to ask and if I am interested then I will certainly give it serious consideration. And no, I don't usually do these for FREE either so please don't expect me to offer my valuable time for nothing!

Many other websites have taken our graphics, and pictures, without out permission. We are not affiliated with those sites. Just because they take our imagery and product photos and put them on their website does not mean that they carry the same highest quality as Six Star Replicas!

Starting with DenyHosts version 2.2, you can now specify all or part of a configuration value to use an environment variable setting. To specify a dynamically substituted value you specify the portion of the value you would like to replace using the syntax $[ ... ] where the ... maps to an environment variable name. Notes: the environment variable must be specified in UPPERCASE and will be retrieved from the local environment when DenyHosts is started.

REBOL IOS is for group communications. It is designed to help people work together in a secure fashion from anywhere and with almost any type of computer system. The unique power of REBOL enables an unlimited range of new applications for information sharing, collaboration, and coordination.

REBOL/Link is the IOS client program that is run by each user. It is available for a wide range of platforms, such as Windows (all versions), Solaris, Linux, BSD, SGI, and others. And, because it comes from a single source, it is perfectly consistent across all platforms. Downloading and installing REBOL/Link takes just a few seconds.

You use System.Reflection to dynamically load a control. This sample loads the SpecControls.ColorControl from SpecControls.dll. [C#] using System.Reflection; Assembly assembly = Assembly.LoadFrom( "SpecControls.dll" ); Type t = assembly.GetType...

This is a very sensitive area and the rule is... Credit where credit is due, please! Good graphics take a lot of expertise to produce. It is amazing that so many authors give them away. If you use someone else's graphics do NOT allow others to think that it is your work. Give the Author credit and add a link back to the author's web page.

The QR5 will generate around 10,000 kWh per year in a good wind site of 5.9m/s average. This is equivalent to five low-energy houses’ electricity demand, or the electrical needs of a twenty man office (i.e. lights, computers, servers, printers, faxes and phones). We are currently determining the full power curve and for this to be independently audited to comply with BSEN 6140012. This will be fully released once it has been established and verified by an external source.

Roughly speaking, you need to start R inside the debugger, load the code, send an interrupt, and then set the required breakpoints. Next: How can I change compilation flags?, Previous: How can I debug dynamically loaded code?, Up: R Programming

For most of the scripts in the Library, you need to donwload the right verison of REBOL for your computer and operating system. The download file size is between 250K and 650K, so it doesn't take long. Some scripts in the Library need alpha or beta versions. They are available from REBOL.net download page. Some scripts run under the REBOL browser plugin. If you have a supported browser and have enabled the running of plugins, the browser will download REBOL for you.

The garabage collector does not free memory until it needs to. Otherwise, it would be running constantly and slowing down programs by a lot.

REBOL is a mix of both closed and open source. The kernel of REBOL, which must be kept extremely consistent between hardware platforms and operating systems, is closed. This keeps platform specific variations to a minimum, allowing your programs to run on Windows, Linux, Unix, and other systems without modification. Our consistent, controlled design process also keeps REBOL very small - its core is less than 250KB. The layers above the kernel are open.

The list of changes can be found at this location. This document will also provide you with the location of new beta test versions.

User the TRY function. TRY will catch errors and return the error as a result. if not error? try [do it] [print "done"] In fact, this form is so common that the ATTEMPT function was created as a shortcut: if attempt [do it] [print "done"] block: any [ attempt [load %file.r] copy [1 2 3] ] Evaluating an error caught with TRY will produce the error unless it is first disarmed with DISARM. DISARM creates an error object from a "live" error.

Have a look at the port code within REBOL. The following will print all of the protocols out: foreach scheme next first system/schemes [ print mold get in system/schemes scheme ] You can also save the source of a specific protocol in the following way: save %ftp.r system/schemes/ftp/handler

Yes secure client-side SSL and HTTPS is supported by REBOL/Command. (Server-side HTTPS is normally supported by your web server.)

REBOL had an ELSE statement in the alpha versions, but ELSE complicated the language because the else had to be searched for each time an IF was encountered. EITHER returns the value of the block it evaluates. IF/ELSE can be used in place of EITHER in the above example.
