Hi Ashley, Just shutting down the instance of Pro in the integrated environment is a much better way of doing it. In this case, there is a distinct advantage of using integrated mapping over MB. The memory leak problem is a real pain but it sounds like you've handled it well.
Map tiles - whether they be images, SVG, Flash or other visual format, can form very powerful web-based apps. I've done quite a few now which have pan, zoom and search facilities. Of course with simply summoning the right map image to display, you can't get a map to centre anywhere. However, I have found with sufficient tile overlaps, the search target is always "in the middle somewhere" and can be marked with an overlaid X graphic. So many web mapping apps have very simple requirements and a map server is simply not necessary. I'm sure MapInfo would like to convince customers otherwise! Finally just a word of warning for any -L'ers who liked the pop-up windows on my Map Gallery and want to play with Overlib.js - I (and others) spotted today that there is a hidden counter in the JavaScript (www.nedstat.nl) and the stats company has now turned off the counter support. To avoid your web page throwing-up a request for a username/password, follow the instructions at http://www.nedstatbasic.net/overlib/ to deactivate the counter.

Hello Ashley, Here's a potential workaround to the memory leak that doesn't involve using the Windows API. Develop your MB program so that it only generates a sub-set of your 70,000 total (say x) and then stores it's progress to a file/table and closes MapInfo (freeing the memory). Then, use Windows scheduling to kick off an instance of mapinfow.exe with your MBX every y minutes/hours. You will need to figure out practical values for x and y but you may already know the average number of images your machine is generating from your 2000 current output. Leave the process over the weekend and then return to the office on Monday with fingers crossed. Even if you have failures, at least your output is being saved and you can resume. Alternatively, use a different version of Pro. This may not necessarily mean upgrading to the latest version. When generating batch images, I usually go back in versions to one that has the features I need (e.g. grid support, etc.). Most of my development is still done in MB v4.5 and tested with Pro v4.5 and higher. One final suggestion with batch maps destined for the web. Given that maps for web use are never very large, sometime labelling is compromised. I found (and adapted) a JavaScript based pop-up called OVERLIB (easy to find with Google) and generated map hot spots for my static images. This was implemented by generating a image map file parallel to each image and using simple server scripting to insert it into each page. The downside is that I could only get it working with Internet Explorer but you/others may have better luck. You can see the results on our web sites "Map Gallery" which has just over 200 small scale maps. Simply hover your mouse pointer over the black dots (which are places) for information - even if the place is not labelled. http://www.europa-tech.com/gallery.htm Regards, Warren Vick Europa Technologies Ltd. http://www.europa-tech.com -----Original Message----- From: Simmonds, Ashley (OPT) [mailto:[EMAIL PROTECTED] Sent: 11 February 2004 01:16 To: [EMAIL PROTECTED] Subject: RE: MI-L memory leak - save window as... alright, i'll give the crispy API solution a shot... and no miss hilton, i can't use alt-prt scrn, in the last day since writing the initial query i've produced over 70,000 map images, my fingers would be worn down to bloody stumps by now. :) as an aside, my process at the moment because it's automated and doesn't need a great deal of speed, just reliability, is closing down and restarting mapinfo after every couple hundred picture dumps. my closest guess to the number of times MI has been auto-restarted during this single process is in the region of 500 times without a single error. tee hee. if you're interested in seeing an example of what's being generated, go here: http://vmedia.webclients.internode.on.net/455/index.html it's nothing special, and certainly not for 56k users as it's designed for our intranet, but it gives you an idea what i'm doing. i've so far generated about 2,000 of these pages. heh. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Tuesday, 10 February 2004 8:38 PM To: [EMAIL PROTECTED] Subject: RE: MI-L memory leak - save window as... Caroline Keyboard controls are OK for interactive editing but not for an automated process - Save Window As (now its working properly in 7.5) also gives you control over the size, resolution and format directly, plus the ability to put in a comment such as a copyright notice. The API call I posted is a neat solution to a problem that shouldn't exist - actually, for my purposes its better but then I'm not keeping the images as Ash needs to.

Shoot me if I'm being a little na�ve here, but can't you just use ALT-Prnt scrn to capture the map windows? This is what I use all the time. I paste them into a photo editor (Microsoft Photo Editor's the one I'm using at the moment), then save as whatever image type you need to dump into other documents. Is this a different result to Save Window As...? The resolution's fine.

Ash/Bill I've put up this link a few times now but I may not have seemed directly relevant - >Grab the contents of the MapInfo window using the HWND into a Picture >object - theres example code on the Micrososft >site at >http://support.microsoft.com/default.aspx?scid=KB;en-us;q161299. This is an API call that gives you a picture object with the complete map in it - instantaneously. No leak. The situation Ash describes ie memory leak on Save WIndow was the reason I ended up going down this route, although my requirement was just for a snapshot of the screen including highlighting during processing in a VB app. If you hoick the contents of the map window into a picture object in VBA I presume you can then use an Access method or another API call to produce your image file - HTH Paul Crisp Syntegra Innovation Place Delta Bank Road Newcastle NE11 9DJ Tel 0191 461 4522 Fax 0191 460 1987 -----Original Message----- From: B.

Summoning a demon by using the sign of the beast for a window id isn't going to help you. Salvation is only for those who upgrade religiously.
