Japanese text, cgi, sql (again)
Hello All, On and off over the last three years, I've been trying to crack the problem of downloading Japanese text which is contained in a mysql database by a stack + rev.cgi combination. It's that time of year again. As with past attempts, my latest too works fine except for the same old problem -- Japanese text arrives in the stack garbled (English text is ok). Having tried a variety of suggestions from this list and from Japanese-users of Rev (the database's and its fields' collations; Rev uniencode/unidecode/ unicodetext commands; etc), my latest thought is the problem may lie with this final part of my cgi script: -- put Content-Type: text/plain cr before buffer -- put Content-Type: text/html; charset = utf-8 cr put Content-Length: the length of buffer cr cr put buffer As the commented-out lines show, I've tried different Content-Type. But not having a full understanding of how this or char-set work, they're just blind guesses. Could the cgi-script's content-type / charset (or something else similar) be what's garbling the Japanese text? Perhaps this year will be the lucky one.

Thanks. -- Nicolas Cueto Hello Nicolas, I'm no expert but, working with mySQL and websites, I have found that the following MySQL command is needed to tell the database what kind of data it is about to transmit (this assumes the data is actually utf-8 of course) SET NAMES 'utf8' You would use revExecuteSQL with the connection id to isssue this after making the connection and before trying to transmit the data. Every part of the process has to be told what kind of data it is dealing with.

How do you know where the text becomes garbled? Have you tried with a 'local' mySQL database? When you send Japanese Text from Rev to mySQL and view it with a 3rd party app like Navicat, does it appear in Navicat as you would expect it to? ie has it arrived in the db correctly? If you use Navicat to: SELECT japaneseTextColumn FROM myTable INTO OUTFILE 'HD/Users/Shared/textDump.txt' does it come out as you expect? If you use Rev's revExecuteSQL command to do the statement above does the file come out exactly the same? (note you will have to use a different file name as mySQL will not overwrite an existing file) If you use Rev's revDataFromQuery command and place the result in a variable and look at it in the Variable Watcher is it what you expect? Does it all fall apart at the very last step, placing the variable into a html document where it is no longer displayed correctly? You say it arrive's in the Rev stack garbled, but you mention html char set, is this in a revBrowser window or do you mean a html document which then displays in Firefox incorrectly?

revDatabaseColumnNamed
Hi I am trying to store arrays (using arrayen/decode) in an sqlite database, and then retrieve them later on. Unfortunately, It seems that I am unable to get binary out of the database. Things I tried: --always the same query, data should be a binaryencoded array put select data from liveData where name=:1 into theQuery --using revdatafromquery (not recommended by docu) put revdatafromquery(,,databaseID, theQuery,theName) into theProp3 --issuing revquerydatabase put revQueryDatabase(databaseID, theQuery, theName) into x --using revDatabaseColumnNamed, no output variable --this is not recommended for binary data put revDatabaseColumnNamed(x,data) into theProp2 --using revDatabaseColumnNamed, with an output variable --this is recommended for binary data put revDatabaseColumnNamed(x,data, theProp) into x --test the data put theProp3= theProp and theProp2 = theProp result= true bvg= :-( Note that doing arrayDecode on any of the prop-vars will result in a runtime error. Can anyone tell me how to store and retrieve binary data using sql, without it being changed in between? thanks Björnke -- official ChatRev page: http://bjoernke.com/runrev/chatrev.php Chat with other RunRev developers: go stack URL http://bjoernke.com/stacks/chatrev/chatrev1.3b3.rev; ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
A fix for the the Help shortcut bug
Hi, One of the most annyong bugs in Revolution is the disfunctional Help shortcut. It is that annyoing because first I notice at least every single day, when I press command-? to open the Help window, which doesn't happen, and second it is extremely easy to fix, really takes no more than 10 minutes. This bug has been around for years and I'm fed up with it. So, here's how to fix it, following the IDE's conventions. Obviously, do this only if you know what you're doing and don't contact support if you're suddenly experiencing new problems after applying this fix (*usual disclaimers apply). Put the following into the message box: edit script of btn revShortCuts of stack revLibrary Search for the line if the shiftkey is not down You will see that this line is the start of an if-then-else control structure, which contains a switch control structure. The last case in the switch is case 7. Add a case, right after the break for case 7, and add a case for the slash (/)/. Now add, starting on a new line: case / send menuPick quote Help Contents quote to btn Help of stack revMenuBar break Optionally, you can paste the following handler at the end of the script: on rawKeyDown theKey if theKey is 268762986 then send menuPick quote Help Contents quote to btn Help of stack revMenuBar else pass rawKeyDown end rawKeyDown This will allow you to press the Help key on the extended Apple keyboard to open the dictionary (it might even work on PC's). Now compile the script. Next, type the following in the messge box and type enter: edit script of btn Help of stack revMenuBar Search for the line case Dictionary and create a new empty line right after this line. Type the following on the new empty line: case Help Contents and compile the script. As a result, the cases Dictionay and Help Contents will do the same from now on. Subsequently, execute the following line from the message box: save stack revLibrary as well as the syntax save stack revMenubar You can now close the script editor windows and you're done. If you tried this without success or if you know a better solution, please let me know off-list. -- Best regards, Mark Schonewille Economy-x-Talk Consulting and Software Engineering http://economy-x-talk.com Snapper Screen Recorder 2.0.1 http://snapper.economy-x-talk.com If you sent me an e-mail before 15 May and haven't got a reply yet, please send me a reminder. ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Whether the result would be of practical use is another question. If your interface is simple, it's probably not worth the trouble. (And if it's complex, I guess the results may be less useable.)

Background image problems
Can anyone shed some light on using paint tools and imagedata on images in a bg group? Here's my situation: I have either 1 or 3 pictures to generate, each held by a separate image object. The user adjusts a bunch of settings and then presses a button to generate new pictures. To let the user see what is happening, the first is always visible, and is supposed to update frequently. Because the new picture might look a lot like the old picture, the script selects some gray color and uses the pencil to draw horizontal lines over the first picture. This is fairly quick and gives a clear impression that the picture is being rebuilt. This works fine if the image is not part of a group. It works if the image is not the only image in a group. It seems not to work if the image is the only image in a group (Rev takes enough time to draw gray over the image, but no partially or fully gray image ever appears). Next step is to generate new images. I take the imagedata for the all gray image, which is automatically the right size, make copies as needed for additional images, and then run through the pixels of each imagedata copy, inserting RGB values calculated on the fly. This is 300x faster than using paint tools. After every 1024 pixels, the script sends the imageData on the screen, so it looks like the image is redrawing a line or a few lines at a time. This works fine if the image is not part of a group and the script includes unlock screen commands. It seems not to work if the image is in a group. Finally, the imagedata of the first image is set to the 1st imagedata, the imagedata of the second image is set to the 2nd imagedata, and same for the third. If all three images are in a group with bg behavior, the second and third look right and the first never updates - it's just gray. This problem persists with a 1-card stack. If all three images are not in a group, they all work fine. This application lends itself to making many cards bearing different pictures, so I was hoping to put images in a group with bg behavior. However this seems not to work. I expect that I can remove the images from the group and make new image objects as needed, but what a kluge. Any thoughts on what is going wrong?

Re: Background image problems
Hi Walt, Instead of telling us what you have done, and that it apparently doesn't do what you want it to do, is there a chance that you can just tell us in good old plain English what it is you are expecting to accomplish? Maybe there is an easier way to do what you want to do that will not produce the chain of events you've described, since I think many of us have ways of doing things that use our own approaches. And there is usually more than one way to skin a cat in Revolution. Just a thought.

If all three images are in a group with bg behavior, the second and third look right and the first never updates - it's just gray. This problem persists with a 1- card stack. If all three images are not in a group, they all work fine. This application lends itself to making many cards bearing different pictures, so I was hoping to put images in a group with bg behavior. However this seems not to work. I expect that I can remove the images from the group and make new image objects as needed, but what a kluge. Any thoughts on what is going wrong?
