Mark,

Here's a suggestion. Just send you listing requent in 300 millisecs
(or whatever works). That should give libURL some time to reset.

Sidescroller (Parallax)

[Malte Brill]

Hi all,

there was some discussion about side scroller games recently. Today  
was way too hot to do something serious, so I played with parallax  
scrollers a bit. Here is what I have come up with. Quick and dirty.


From your Messagebox:

go stack URL "http://www.derbrill.com/aforest.rev";

(half a meg, so if you are on dial up it might take a while.)

or download the zipped version:

http://www.derbrill.com/aforest.rev.zip

Hope you like it, even though I must admit it is still a bit too CPU  
hungry.


All the best,

Malte

You can avoid virus checkers by wrapping the COM calls in a "normal" DLL (or
one developed in VB if you like):

I can guess.  Well, there are problems in getting the size and  
imageData right at the same time.  Also, I'm told it is based, not on  
the image, but on the display of the image.  I think the size and  
angle might affect it.  Also, Chipp has found that it is not the same  
platform to platform, that it seems be a collection of some rendering  
values.  My experiments show that PNG gamma affects the imageData  
values.  It has problems with a newly drawn image.  It doesn't  
collect size and pixels including alpha all in one place.  It doesn't  
have room for comments (I think the unused bytes in imageData become  
zeros or did at one time).  Maybe it would be less of a draw if  
imageData worked as expected.

Re: LibURL Error Previous request not completed

[Dan Shafer]

I had this problem repeatedly during recent attempts to create an FTP-based
app. I found that after receiving that error, I could resubmit the request
and almost 100% of the time it would process successfully.



On 7/27/06, Mark Schonewille <[EMAIL PROTECTED]> wrote:


Hi,

Right after uploading a dozen of files to my ftp account
asynchronically using the libUrlFtpUploadFile command, I can't get a
directory listing using the syntax: get url "ftp://
name:[EMAIL PROTECTED]/folder/" (note the trailing slash, as I want
a listing). Most of the time I receive the error "Error Previous
request not completed".

It appears the GetURL handler in the revLibURL script doesn't let me
get the url because the variable lvBlockingUrl is not empty. Although
everything has been uploaded/downloaded already, lbBlockingUrl
indicates that one or more transfers are still in progress. So, in
the GetURL handler, I changed the line which checks whether any url's
are currently being handled and added variable to force the handler
to run normally:

   if lvBlockingUrl is empty or lvBlockBypass is true or
lvAuthBlockBypass is true or lOverrideBlockingUrls is true then

The variable lOverrideBlockingUrls is from me and is set using an
additional command. If lOverrideBlockingUrls is true, getUrl still
runs as expected. I am not sure that this is a solution, though.

Additionally, many repeat loops like these

if laLoadReq[tUrlHolder] is empty then
 repeat until laStatus[tUrlHolder] is not empty
   if lvJumpOut then exit to top
   wait for messages
 end repeat
   end if

in LibURL never finish. Probably, this means the laStatus[tUrlHolder]
is always empty or lvJumpOut is always false.

First, I would like to know, is this likely to be a bug in the libURL
library, or am I doing something wrong? Second, before I start
debugging libUrl, is there a simple way to prevent this problem from
occurring and did anyone see this problem before? If there is no
solution for this problem yet, what would be a good place in the
library to start debugging? I need to solve this problem now, so
every idea is more than welcome.

I'm using Rev 2.7.2 on Mac OS X 10.4.7.

Re: Why is the imagedata value different from Win32 to MacOS platforms?

[Ben Rubinstein]

For image processing I have to extract the RGB values from an imagedata

I found that the imagedata values is different between the two platform: 
every color component of pixels is slighty changed. I have not found in 
the documentation such a change depending on the platform. Notice that 
 is identical between both platform.


Could anyone give me a clue?


Joel,

Is it possible that your Mac and Windows platforms were at different depths?

I did a few tests, and noticed that the histogram of an image imported under 
Windows was much 'cruder' than the same image imported under Mac.  It occured 
to me that Windows was using some cheaper algorithm to expand the JPEG data, 
not using as many bits per pixel.  Then I checked, and found that my Windows 
machine (actually a VPC on my Mac running in 24-bit) was in 16-bit colour. 
When I changed the Windows one to 24 bit, they had the same imageData.


So - unless you tell me that they were both set to 24-bit colour - I think 
there's a perfectly straightforward explanation.


The image is imported from a JPEG file; Rev stores the actual JPEG data as the 
'text' of the image, ie what gets actually saved in the stack file.  When the 
image is displayed, it is rendered into a buffer, which is probably the same 
depth as the screen (or alternatively, perhaps the buffer is always 24-bit, 
but the JPEG expansion code operates in a way based on the screen depth). 
Either way, when you ask for the imageData, you're getting a 5-bits per 
channel pixmap expanded to 8-bits per channel - hence the slight differences.

I'm having trouble understanding why anyone wants it.  (This is sincere, not
snide.)

If you want to examine the pixels of an image, or modify it, use the
imageData.  It's by far the easiest format to work with.

If you want to create an image based on data in a standard format, use the
import command.  If the data is in memory, I can't imagine many situations in
which it's tough to bounce it off a temporary file on disk.  If the format is
PNG or JPEG or GIF and you really don't want to store it temporarily in a
file, you may be able to set the paintCompression appropriately and then set
the 'text' - I'm not sure if this works (or if paintCompression makes a
difference to the interpretation of the incoming data).

If you want to do the reverse, create a description in a standard format, 
based on an existing image, use the export command.  Maybe you can also get 
the 'text' of the image, but I don't see the advantage given that you can 
'export' into a wider range of formats, and can do so into a container or file.


If you really want to change the format in which the image is stored
internally in the stack record you can: change the global paintCompression and
then modify the image (I think just "set the imagedata ... to the
imagedata..." will do it) and change card.  But again, I can't imagine why
you'd want to do this, which will generally reduce image quality.  (I suppose
there might be a few cases in which you know that you can reduce the stored
size of the image without reducing image quality, or where you're prepared to
accept the quality loss.)

But why does anyone care what the RLE format is?  It's just used internally.
We don't need to understand the internal format that a field's data is stored
in, as long as we can get at it by properties.

For the record, I'm pretty certain that isn't Utah RLE, but a very very very
much simpler format.  Take a look at it and see.  But I still wish someone
would explain to me why so many people seem to care?

Re: Play command gone quiet

[J. Landman Gay]

Answering my own question:
Ever since then, Rev can't play sounds any more with the "play" command. 
This has persisted through several machine reboots. It can play them 
inside a player but not with the play command. This is a global problem 
too, since MetaCard and other older versions of Rev can no longer use 
the play command now either.


Does anyone know how to get this capability back? Any idea what got 
hosed? Needless to say, Audacity probably isn't in my future any more.



Never mind, I found the answer here:



Audacity sets the global system sample rate higher than most apps 
(including Rev) can use. You have to launch Audio MIDI setup and set the 
rate back down to 44 kHz to fix it.

Play command gone quiet

[J. Landman Gay]

This may be a tad off topic, but it concerns Rev. I am converting a 
stack to Revolution that has hundreds of "play" commands in it. Since 
there are so many, I decided to just use them as-is rather than change 
everything to use players. This has been working fine for some weeks.


Yesterday I used Audacity for OS X to convert some sounds. It turned off 
my system sounds globally and nothing I could do in the System Prefs 
would turn it back on. The "beep" command did nothing, Thunderbird no 
longer beeped when mail arrived, etc. Rebooting the Mac restored it.


Ever since then, Rev can't play sounds any more with the "play" command. 
This has persisted through several machine reboots. It can play them 
inside a player but not with the play command. This is a global problem 
too, since MetaCard and other older versions of Rev can no longer use 
the play command now either.


Does anyone know how to get this capability back? Any idea what got 
hosed? Needless to say, Audacity probably isn't in my future any more.

I know this discussion has gone on a while and I don't have any current
interest in the result, but couldn't someone just write the different data
formats to a file, then look at the hexDump (using BBEdit or other) and
compare them?  Even 'set the clipboarddata to the imageData' etc

put the imageData of image orange into imgData
put url binary: jpg into picRaw
is imgData in picRaw
put offset(imData, picRaw) into firstHit

You know, stuff like that?

I don't have time to do any digging this week, but that might shed light on
what happens..when..if.. maybe..

Sorry, that was a bit gnomic!

Confession: I've not really immigrated to 2.7 yet, but spend most of my time 
in 2.6.1, with occasional dipping of toes into the modern world.  So I started 
looking at this in 2.6.1, and then checked my results in 2.7.


In 2.6.1, the pattern seen in the message watcher when typing into a field is 
as follows:


I type 'c':
   rawKeyDown
   keyDown
   rawKeyUp
   rawKeyUp
   keyUp

   and c is entered in the field

I type option-c:
   rawKeyDown
   optionKeyDown
   rawKeyUp
   rawKeyUp
   keyUp

   and c-cedilla is entered in the field

I type option-u:
   rawKeyUp
   rawKeyUp
   keyUp

   and nothing is entered in the field

I type u (immediately after option-u):
   rawKeyUp
   rawKeyUp
   keyUp

   and u-umlaut is entered in the field

The pattern in 2.7 is the same (ie no rawKeyDown or optionKeyDown for the 
sequence option-u, u) - except without the duplicate rawKeyUp seen in each 
sequence.  So it looks like that was a bug that was quietly spotted and fixed 
(I can't see anything about in Bugzilla) - but without addressing this problem.


There.  Full disclosure!

I can guess.

Normally, a gif is limited to 256 colors.  An imageData can represent  
lots more.  So when an imageData is set, the engine creates a PNG for  
it.


Some folks have noticed that the same PNG has a different imageData  
on different platforms.  I have noticed that removing the gamma from  
a PNG will change the imageData of an image object it is put into.


So, if the fetched imageData is after some fiddling, does setting the

in the image so the image pixels equal the imageData pixels?


Just wondering.

All,

I've spent a little more time this morning trying to further reduce 
the scope of my ignorance...


1.  I created a stack and imported the wininfo.gif and wininfo2.gif 
images from the Rev Image Library, and duplicated the first

From the Message Box, "the paintCompression of image 3" puts "gif"

2. set the imageData of image 3 to the imageData of image 2
From the Message Box, "the paintCompression of image 3" puts "png"

Why?

Rev knows the paintCompression of image 3.  When it changes image 3's 
text property based on the imageData why is it converted to png 
format instead of, in this case, gif format?

EcxFTP 1.0b08 released

[Mark Schonewille]

Dear Revolution users,

We have just released another beta version of ecxFTP. Compared with  
the previous officially announced beta version, there are striking  
improvements, such as a series of buttons on top of the client window  
and overall improved responsiveness. During the past six months, many  
of you sent their comments to Economy-x-Talk and we are very grateful  
for your help. We have paid attention to all your comments and fixed  
all reported bugs that we could reproduce. A change log is included  
with the software.


We are releasing a new beta version, which is available for download  
now. The current beta version of ecxFTP has been created and tested  
on Mac OS X 10.2 up to and including 10.4.7. You can download ecxFTP  
at the following address:




where you can find versions for both Mac PPC and Mac Intel.

We would very much appreciate a detailed description of your  
experiences with ecxFTP. Please, don't forget to include information  
about your Mac model, operating system version, AppleScript version,  
amount of built-in memory, applications running simultaneously, and  
any other information that you deem relevant to us. Valuable bug  
reports are rewarded with a free license. With pleasure, we grab the  
opportunity to offer other Revolution users 50% discount.


We will be licensing ecxFTP in the near future. Quite a few  
Revolution developers are struggling making their own FTP client,  
usually for a specific server or application, such as backup  
services, content management systems, on-line stores, or workflow  
systems. Economy-x-Talk will gladly provide you with a license  
allowing you to build the FTP client stack into your own Revolution  
project. Alternatively, we integrate the stack in your project,  
saving you the time to figure out how things work. Contact us for  
more information about the licensing scheme.


Best regards,

Mark Schonewille

P.S. Comments, feature requests and bug reports can be sent to  
[EMAIL PROTECTED] We would be very pleased to receive your  
feedback.

Problem using Launch when application is already open

[Martin Blackman]

Could someone please tell me how to open a file in an application
thats already open ?

eg using 'launch tfilename with (tOfficepath&"/Excel.exe")' does
nothing but sets the result to 'process already open' if Excel is
already open.

There is a twist - I can't just use 'launch document tfilename' as I'm
using office 2003 xml format which is by default opened with internet
explorer.

Re: VB COM in Revolution?

[corvideon]

Hi Sarah

You may find the following article useful:

http://en.wikipedia.org/wiki/Component_Object_Model

COM is a way of creating an 'in-process' object of some other application.
For instance in VB you can create a word application object in your code and
then manipulate word documents using the methods of that word object as if
it were part of your program. The difference with RunRev is that you have to
rely on a VB/Vbscript program to create the COM objects. You pass parameters
(through shelling out) to the VB/Vbscript program  and it can then pass
these onto the COM object. This runs in a seperate process to your RunREv
app (I think)

AFAIK RunRev does not technically support COM, but can use an external
process to manage COM objects on it's behalf  - which is nearly as good.
Look up 'DLL hell' in Google to see the fun you are avoiding...

That is the case as far as I know. If anybody can correct me, I would be
happy to learn more.

Seamus Brady

Re: VB COM in Revolution?

Dear Sarah,

Revolution can indeed communicate via VBscript/VB to a COM object in  
much the same way as Revolution can communicate with an application  
via Applescript and an applications dictionary.

Do you happen to know if COM is available in Runtime Revolution?


I know almost nothing about VB but from discussions I've read on this
list, COM is not just a reference to a serial port but can be
something similar to AppleScript for inter-application communications.
Is this correct or am I way off the mark?

Anyway, can someone with more Windows expertise than me please help me
answer this question.

This is bug 1147, which for some reason is marked fixed.
This leak of keyboard typing to the field is a serious (or at  
least embarrassing) problem for 'ask password' and casual  
implementations of password dialog boxes.

It is probably a problem with many applications that use KeyDown.


Yikes!  Thanks Dar, I didn't know this.  It's a nasty one, since I  
can't see any workaround.


Interestingly the behaviour has changed a bit between 2.6.1 and  
2.7.2, but not fixing this bug.  I've added a report to BZ 1147  
confirming that this is still a bug in 2.7.2 on Mac OS X 10.7.4 -  
but I can't re-open the bug, only Klaus or someone at RunRev can.


Klaus - could you re-open this bug please?


I just re-opened this bug.
