CSS Designer problem

I am on the fifth tutorial. It was going fine at first, but now when I try to edit the properties of a selector in the CSS Designer, every time I change a value it somehow exits the properties page (and the selector) so that I have to select main.css and then select the selector I was working on (#mainnav ul) again to be able to continue editing the properties. This wasn't happening before, so I'm not sure what happened, if I inadvertently changed a setting or what. Please help! It will take me forever to do anything if I have to navigate my way back for each property I need to edit instead of being able to do it all at once.

I'm still not sure what the problem was, but quitting Dreamweaver and opening it again seemed to solve the problem. I would be great to know what the cause was, though, just in case it happens again. (Or so I don't make the same mistake again). If anyone has an idea, your thoughts would be much appreciated

Problem with CSS Designer in the Panels

Hello,
I have just joined Creative Cloud, I have downloaded the newest apps. In Dreamwever I cannot see the CSS Designer in the panels. After a few ours of looking for solution for this problem (all throw Internet inclusive this Forum), I have to ask you dear helpers to help me.
So, where I can find CSS Designer in the Panels? It is not on the right side, it is nowhere.
Thank you in Advance

Dear John,
Thank you for you answer.
I lost many ours looking for what is wrong with my CC Connect, Dreamweaver... I would suggest to Adobe to put a small info on a visible place for people to know about this.

Problems with css-designer Panel

can't display CSS selectors/properties - just gives me an empty grey area. When I click in this gray area, dreamweaver crashes.
Does anyone have similar problems and can help?
Thanks in advance!
(OS X 10. 7. 5. / macPro)

very strange - I installed Illustrator CC and then I had no more problems with Dreamweaver! No more crashes when close or create files and no more problems with the CSS designer. Error messages during create fluid grid layouts are also gone ...
Congratulations "pcepp" that you too have found a solution.

Properties disappear in CSS Designer panel intermittently

I am experiencing the properties for a CSS rule dissaperaing intermitantly from the CSS Designer Panel but not reappearing in CC since the latest update. The only way I have been ableto fix this has been to quit DW and re open. Sometimes happens 3 to 4 times in a row then maybe not for days. I am using fluid grids for this project. Has any one else experinced this and is there a fix.
Very anoying bug - seems the last update created more than it fixed

The link to the latest page this is causing a problem on is...
http://www.branchingoutcairns.com.au/services.html
.....there are others from other projects which leads me to believe it is a DW bug but have a look you might pick up something for which I would be grateful
The issue comes around when ever you try to alter padding or margin or corner radius and not all the time - as I said could happen forur times in a row or not for days

No CSS Design View?

I'm a guy that usually likes to style apps using an external CSS and selecting a component to style, and having a way to add that component's properties/styles to edit.
Flash Builder 4 has done away with this, but to me it feels like it's going BACKWARDS.. but it's probably something I'm missing, so I'd appreciate the way people are using it...
So right now it seems like I can set styles ON a component, and then MOVE it to the existing CSS file I have, but I want to make sure that this doesn't leave ANYTHING within the code view that is styled? I tested it and it seemed to leave backgroundColor in the mxml declaration.
On top of that, there's no autocomplete for any CSS in the CSS view?
Just seems for CSS view you're somewhat stuck to doing it all by hand again...

What SDK version are you using?
Let me start with the easy questions.
Autocomplete in CSS
Code hinting is supported in the CSS editor. If you're in a Flex 4 project, make sure you're using namespace qualified type selectors http://opensource.adobe.com/wiki/display/flexsdk/CSS+Namespaces+Support. That's the typical problem people have during the transition.
CSS Design View
There are a few reasons why CSS Design View isn't supported for Flex 4. Flex 4 skinning, in many cases, replaces CSS styles. For example, backgroundColor isn't supported for every component. For more information, see http://opensource.adobe.com/wiki/display/flexsdk/More+Styles+for+Spark+Skins or the Flex 4 reference http://help.adobe.com/en_US/flex/using/index.html. CSS Design View is supported for SDK 3 projects, but not for SDK 4.
Can you explain in more detail what you mean about setting styles on a component and moving them to a CSS file? Sounds like you're using Design view to set styles in MXML then convert them to CSS declarations. This should be fine since Design view should only let you set valid style properties.

CSS Designer to old visualization

Buongiorno a tutti,
sono passato da Dreamweaver CS6 a Dreamweaver CC 2014.
Nessun problema, tranne per la gestione dei CSS: il nuovo CSS Designer è scomodo e poco funzionale per me. Ero riuscito per caso, tramite una scorciatoia da tastiera a visualizzare il vecchio pannello "Stili CSS". Di fatto però non riesco a ritrovare questa scorciatoia per passare da un pannello all'altro. Qualcuno di voi sa aiutarmi?
Grazie.
Daniele

Nuovamente buongiorno,
provando scorciatoie da tastiera sono finalmente riuscito a trovarla: a chi interessasse il comando per passare alla vecchia visualizzazione stili è Ctrl+Alt+Shift+P
Buona giornata a tutti.

CSS Designer in Depth | Creative Cloud for Web | Adobe TV

Get an in-depth look at the powerful new CSS Designer tools in Dreamweaver CC. Intuitive visual editing tools help you generate clean, web-standard code and quickly apply CSS properties like gradients and box shadows. You can see the effects on your designs immediately, eliminating tedious tweaking and the need to go back and forth to Code view.
http://adobe.ly/ZSeWkr

The new CSS Designer feature in Dreamweaver CC is a very nice addition to the interface’s workflow. However, it’s not best for all workflows, whereby there should still be a non-assisted CSS editor option available, like in CS6, “without” all the new visual designer tools.
In CS6’s CSS properties editor you can quickly glance at the currently selected element’s CSS properties and directly edit the actual property values in a column format making this a very precise and straightforward workflow process.
For me, the ability to quickly edit CSS properties by clicking on respective elements in the design view editor is the biggest advantage and real power for using Dreamweaver over notepad type editors. Without this option (when working in split mode), it requires switching back and forth between different style-sheets and code view.
Though I really like everything else I’ve seen so far, in this latest version, this seemingly small feature restriction will considerably slow down my overall typical workflow process in most cases. So, until a non-assisted CSS properties editor option is available, I’ll continue using CS6. Please, please fix this soon! Hopefully this is only a short-term oversight and resolved in a very near future update.

Design problem with Swing

Hi all. I've run into some design problems when trying to create a Swing app.
I've got a non-graphical class that emulates a power supply unit. Let's call it PSUnit. I have to create a GUI for PSUnit.
Every class designed to build a full GUI app uses PSUnit in some way (changes its voltage, displays voltage, turns it on, turns it off, etc.)
Here's the catch. Suppose I've got a class:
public class BuildingBlock extends JPanel {
     // code includes a JTextBox displaying
     // the current PSUnit voltage.
}another class is created for setting the voltage:
public class AnotherBlock extends JPanel {
     // this class contains a JSpinner and
     // a button that retrieves the JSpinner value
     // and sets it as the current voltage of
     // PSUnit
}When the button in AnotherBlock is clicked, I must notify the BuildingBlock class that a PSUnit has changed its state so it can update it's values and display the correct data.
I've tried to do this a few times but failed miserably, so I'm hoping you guys could help me out.
Please note that both of the above classes have some additional code and it's not very pleasant to make one class an inner class of another. I should be able to create a "standalone" classes which, combined together, form a GUI for PSUnit.
Thanks.

Yes this is a common problem that many of us have when building UIs
Here's the question: In this instance, are these two classes really independant? Could they stand alone? Often when building a GUI, it's not even that easy to answer that question, but these leads to the two ways you can solve this
#1. Make them independent, and use listeners either using Observable / Observer or creating your own custom listeners. The advantage of this is smaller classes and more independence. The disadvantage is it's generally more complicated, especially at the design stage
#2 (what I'd probably recommend). Make 1 GUI class "MyPSFrame", then declare your panel classes as inner classes within that class. This way, everything goes into one spot, and everything is shareable. This also makes sense if you can't have 1 of the panels without the other.

Design problem about repreatable entity relationships

Hi all!
As I design the data model (let's name it the ERD, no matter the name is quite unfashonable), I have found almost identical structures of entities and relationships between them, but playing completely different roles in the semantics of the model.
It obviously makes no sense to implement all such entities separately as the Entity EJB as they are to share most of the fields and methods, but I found no "handsome" solution when trying to implement them as sets of classes and interfaces forming "the abstract EJBs", and then by putting the conrete classes and complementary interfaces at the final packages to create "concrete EJBs". The problem was about types returned by the createXXX and findXXX methods, because they had to return the "abstract" EJBs but the EJB programming contract forces them to return the "concrete" ones, that are unknown to me when defining the "abstract ones". So it cancels the sense for creating them this way. It was also unclear how to operate the relationships in such model.
The idea was:
1. I define BaseSthLocalHome extends EJBLocalHome
2. I define BaseSthLocal extends EJBLocalObject
3. I define BaseSthBean implements EntityBean
... this way I have the "abstract bean", and then I can create many:
SthOneLocalHome extends BaseSthLocalHome,
SthOneLocal extends BaseSthLocal,
SthOneBean extends BaseSthBean ... to have the first "concrete" EJB,
SthTwoLocalHome extends BaseSthLocalHome... and so on to create the second, third and all the next "concrete" EJBs.
Anyway, it did not work fine as I defined createXXX and findXXX methods at the BaseSthLocalHome interface - it made sense, because those methods did not depend on the other entities.
Has anyone some idea of how to solve the design problem? Currently we are at very beginning of the project, so we have some "case study" time, and I would appreciate any solution: redesign of the data model, extraction of new EJB modules or any use of the objective inheritance.
Thanks in advance!
Marcin Gawlik

Again me - I now it is a bad idea to reply for own messages, but I have just checked a new idea:
The problem was about re-using the same components in different roles. I tried to do that by creating subclasses of the EJB classes, but it did not work. So I tried to define multiple entity EJBs that have the same class.
Considering the given example, it would look:
1. public interface BaseSthLocalHome extends EJBLocalHome
2. public interface BaseSthLocal extends EJBLocalObject
3. public abstract class BaseSthBean implements EntityBean
... then I created the deployment descriptor that deploys this pack of class and interfaces as three separate CMP Entity Beans:
1. deploy BaseSthBean as the SthOne CMP entity EJB
2. deploy BaseSthBean as the SthTwo CMP entity EJB
3. ... and so one
The question is: IS THERE ANY CONTRA FOR THIS WAY OF DEPLOYING EJBS? Is there any reason for not to use the same class and its complementary interfaces many times to create many separate enity EJBs working within the same EJB module?
Thanks in advance!

Design problem/Exercise Book

Hi Everyone,
I am new to Labview. I just started with Labview 2011 student edition and I am following Bishop's book. But I also want a tutorial book with lots of design problems and exercises to get my skills. I am a postdoc in purdue and I started learning LabViews just because I want to learn (I am facinated by the G programming. I use it in my instrument but the departmental engineers wrote it and I want to have the same type of skills. I am also intending to become CLD). Can anyone suggest me any book or any website where I can find exercises and design problem? Thank you everyone.
Cheers!
Solved!

Design problem with JScrollPane

First, I have problems with english. I hope u understand without problems that Im trying to say here. Sorry about that.
Mi problem is whit a JScrollPane. I want to put an image whit a predefined size for draw inside it. I dont have any information about it, just the size. I want to put it in a JPane. The best choice is use the JPane area. The problem is that I want to use a JScrollPane because the image is bigger that the visualization area.
Im unable to put a Canvas in the ScrollPane, or a JPane whit a predefined size or an image whit a predefined size. Im sure that is a design problem. Somebody can tell me something I can start whit? What do u think is better choice to put inside a JScrollPane?
I dont send any source code because I dont have anything else that is show in the example.
Gracias.

Design problem: Central MessagePool in WebDynpro App.

Hi people,
I have a design problem in my webdynpro application:
I'm designing an application with different DC's. The architecture of the application is similar to the architecture described in the document "Web Dynpro Component
Interface Defintions in Practice SAP NetWeaver 04s": One root DC which manages the differnt child DC's, which contain the application content.
Now I want to have a central MessagePool. Certain Messages in the child DCs are the same, and I don't want to have multiple MessagePool-entries for the same Message (each child DC has to define its own messages). I can't use the root DC as central MessagePool, because the Child DCs havn't access to the root-DC.
Any idea, how to define and use a central MessagePool?
Regards,
Thomas

Hi Thomas,
Instead of the architecture what you are thinking try the architecture explained in the following link:

Design problem: RS232 communication

Hi,
I have a design problem for communication with a device via RS232. Since I'm normally a C++ programmer I might just look at the problem from a wrong angle and hope for some hints how to do it in LabVIEW.
The scenario:
A device is communicating with the PC via RS232. The device permanently sends data packets. At the same time, commands can be sent to the device and it returns replies. Data packets and reply packets are arbitrarily mixed, i.e. after sending a command there could be a couple of date packets before the reply comes back but the packets can be distinguished by an identifier.
At least one, ideally several VIs should communicate with the device. Commands should be sent by pressing buttons and the incoming data should be parsed (the packets contain mutliple data streams) and shown on graphs or saved to files.
My initial idea:
Coming from C++ I wanted to build a class for the communication that permanently reads the incoming data and splits it to reply and data packets. This class would then have a function to send out a command and would return the reply or a timeout and it would be possible to register and unregister listeners (I wanted to use queues for this) for the various data streams.
The problems I ran into:
There were a couple but the two most pressing problems were: how could I communicate with the constantly running sample VI (e.g. to stop sampling) and how could I propagate changes to the class to it (e.g. new listeners). Since it is not returning I don't see a good way to implement it as in instance funcion (i.e. pass it the object). I could probably not let the sample function run continously but call it periodically from outside. However I planned to implement the class as a singleton, so it could be used parallely from different VIs.
Is there a best practice for a case like this?
I'm glad about any hints or ideas.
Thanks,
Tobias

Hi,
thanks. Since almost the same thing was suggested to me in a German forum I guess this is really common practice (using one VI with different methods controlled by a queue). It still seems a little "unnatural" for me but my biggest concern (bad interface description) was shattered by the suggestion in the link you sent me to wrap these functions with wrapper VIs, thus caller VIs won't have to deal with the call-by-queue-mechanism. This might also be easier to port to a different implementation later. However I still see the danger that the continously running VI could easily become bloated.
It also requires me to change the way I have looked at VIs until now. In our course they told us that VIs are basically functions. Using this design patterns, the VI becomes more of a module, really (Like a C module implemented in a C-Source file). But I will try it. It sounds as if it could work.
I will still look into the OOP solutions a little more, though. Do I understand you correctly that you wouldn't recommend using LVOOP because it's still buggy? What about dqGOOP for example? This sounds like it could do what I need (however it doesn't seem to implement things like polymorphism, late binding and inheritance so I don't quite see what's so OOP about it. It seems more like programming with structures in C.)
I don't know if LVOOP is buggy or not. I think early on it was buggy and things have improved in recent versions. I have read that it doesn't have all the features that you would have in OOP like C. I wouldn't recommend it only because I'm not familiar with it at all. I can't recommend something that I'm not comfortable with. If you go that route, plan on spending time in these forums and in LAVA to reading up on what others have done. I haven't hard of dqGOOP.
But back to your suggestion. I still have a couple of questions:
- How do you return values from the module? Would you use a queue for that as well?
- Where would the parameter queue be held (created and passed to the VI)
I would store all of these in a functional global variable. This is the VI that stores data in shift registers. Ben's action engine nugget is an advancement on that. This allows for both the calling VI and the parallel running subVI to get and set the data as needed. It runs quickly so neither process should be forced to wait while the other VI is doing its thing.
- My VI has to be constantly sampling and this shouldn't be interrupted too long by other functions as adding a listener. However both functionalities have to access the same kind of data. Is there an easy way to parallelize this? Would the sampling be a case in the case diagram that's always used if no command was sent to the VI or would it somehow run parallely? Yes. There are a couple of ways of doing this. One would be for the dequeue to have a timeout function. In the event the dequeue times out, you run the code that is doing the acquisition. I think a better method is that the code that does the acquisition enqueues its own command again to the end of the queue. Let's say that is command A. So when case A finishes, it enqueues A, which seeds itself to run again. So if nothing else comes into the queue, it just executes A , A, A, A. But let's say another section of code needs to do something such as command B. It will slip B into the queue while A is executing. So you would A, B, then A again, because A would get slipped back into the queue when the first A finishes, but B has already been put in while the first A was running.
- Would it be possible to make the VI reentrant and in this way use it simultaneously on different COM ports (using different parameter queues as well)? I'm not sure if I will need this but it would be neat if it could work.
I think you could do this. It may be a case where the VI is saved as a template (.vit) and you initiate it multiple times. I haven't needed to do this before, so I'm afraid I can't provide any details or useful tips.
Well, I will fool around some more. Thanks so much for your help. This is kind of exciting since the concepts are quite new for me. Btw, is there something like an academic theory (computer science) for LabVIEW? I came across functional languages in university but data flow languages are still a new concept for me.

tfritz wrote:
Another question about the "dynamically starting" of the VI:
How is the path handled? Is it guaranteed that it always takes the VI from the project or does it just search for the first VI by that name it finds in the file structure? Does this still work when building an .exe from the project? What happens if the VI is already running? Can you test for this?
While I'm at it: is there a way to stop LabVIEW from searching for subVIs it can't find when openin a VI? This resulted in very unexpected behaviour sometimes where it would find the VI somewhere else (with the same name but maybe an older version).
In my case, I just had the path hardcoded. It is my only instance, I'm not planning on moving the VI's. If you don't have the path, it will take a VI by that name if it's in memory. If it isn't in memory, it starts searching relative to the calling VI's path. One thing I know, if you are dealing with relative paths, a subVI has a different relative path in an .exe as opposed to the development environment. The name of the .exe becomes a folder. So in development, if your sub VI is mySubVI.vi. In an executable, its path is MyExe.exe\MySubVI.vi
For all of this, I recommend searching the forums to get more details.
If it is searching for a VI, you can hit ignore. But of course you'd have to do it before it finds it. When you are dealing with versioning issues, I recommend making a backup copy of the entire directory structure elsewhere. Some location where it shouldn't stumble across it.

Flash Builder 4 CSS Design Mode

Hello,
     I would like to know why CSS Design mode was removed from Flash Builder 4?
     I am a Design/Developer so it was much easier for me to use CSS in Design mode.
     What are my options? Is there any other tools for visual editing CSS for a Flex application?
Thanks

Hi Fernando, sorry for the delayed response. CSS Design Mode is not available for Flex 4 projects, but it is still available in Flex 3 projects. The reason for this is that designing components in Flex 4 is often a lot different, since it relies highly on the new spark skinning architecture. There is, however, an Appearance panel available in design view which supplies a set of the main inheriting styles. Setting these styles in the Appearance panel will result in assigning values to a global style selector.
I hope this helps,
Rob

How to set image border with CSS Designer?

I must be missing something obvious...
I need to set an image border. I select the image. But I don't see any relevant inline style option in CSS Designer.
It only lets me change <inline style> : td but there's no option for the image.
What am I missing?
Thanks,
Leo

Thanks John,
Yes, obviously I select the image.
However, it doesn't change anything.
I don't get the "img" selector whatever choice I select it the Sources pane.
What am I missing?
