Relatives width and scrolling

Hello,
I just read manual for flex and have got small
problem/question while playing.
I am building application with one Panel and one button in
vertical layout.
I am setting Panel width to 100%.
On start I see layout as expected: panel with width for
entire page (excludding default padding) and button on next line.
Now I am adding code to button - on click I am adding objects
to panel, one by one in horizontal line.
It is also ok, on button press you see that new objects are
created.
But, when entire panel is full of objects I expect it to show
scroller for me, but instead of this panel increases in size
itself, and this adds scroll to entire application, not panel.
If I will set panel's width to absolute value (500) - it
works ok, scroller is shown
Could anybody explain, how can I make panel be 100% in width,
and show scrolling for it content?
my code is attached...
thanks

Unfortunately there is no option by which you can change the width of column in list.

How to resize window keeping relative width and hieght

Ok as usual I do not want this done for me but I could use a pointer. Simply put I wish to set a JFrame so that when it is resized by the user it holds its relative width and height.
Could somebody point me to where it is at in the API or a generic sample of code that I can rework? I have read for it but am not finding it so far. Thank you for your patience and any help offered. If it matters I'm doing a fairly simple app in NetBeans not an applet or anything.

HP Advisor Dock - Customize Width and Scroll no longer working.

Hi there,
I've seen quite a few posts about not liking the Advisor Dock because it takes up space but I on the other hand quite like it. I put a lot of my shortcuts and icons there because it saves space and I could scroll between different icons just by swiping.
Without going into too much detail, my HP advisor just updated itself and now the slide to scroll feature doesn't work. it just picks up an icon and drags it.
Is there any way I can reenable this ? is there a config file somewhere?
I noticed they changed the size of the bar as well, possibly to fit their new lines of products but I'd like to resize it back to the way it was also.
Can you help?

Hi eg1978
Welcome to the HP Forums! I see that you are having issues with your two finger scrolling. I have a couple of things for you to try. This HP document Using and Configuring the TouchPad has a section on Turning individual gestures off and on and make sure that the two finger scrolling is enabled. If that does work then reinstall your Synaptics TouchPad Driver.

>>if i am rendering html from MemoryStreamor string in webbrowser control in wpf It's not applying this css
Yes it does. If you for example add background-color: yellow; to the stlyle you will see that the page turn yellow:
strHtml = strHtml.Replace("<body>", "<body style=\"-webkit-column-width:800px; background-color: yellow; overflow:visible !important; -moz-column-width: 800px; column-width: 800px; -webkit-column-gap: 0px; -moz-column-gap: 0px; column-gap: 0px; -webkit-column-rule: 0px solid #000;-moz-column-rule: 0px solid #000;column-rule: 0px solid #000; height:800px; ; margin:0px; -moz-margin:0px;-webkit-margin:0px;display:block;\">");
If the styles doen't get applied as expected it is a browser issue. The WebBrowser control emulates Internet Explorer in IE7 rendering mode by default. You will have to change some registry settings to change this behaviour. Please refer to the following
links for more information:
http://weblog.west-wind.com/posts/2011/May/21/Web-Browser-Control-Specifying-the-IE-Version

-moz-column-width only works in FireFox for example.
You may also navigate to an actual page and inject some javascript function that for example adds the styles to the body element dynamically or set the style properties of the body element directly:
private void Window_Loaded(object sender, RoutedEventArgs e)
MainBrowser.Navigate(@"E:/Epubs/ePub2_Sample05_Biology_SampleChapter_EN/OPS/ch01.xhtml");
MainBrowser.LoadCompleted += new LoadCompletedEventHandler(webb_DocumentCompleted);
private void webb_DocumentCompleted(object sender, NavigationEventArgs e)
WebBrowser webBrowser = (WebBrowser)sender;
dynamic doc = webBrowser.Document;
//int _scrollWidth = (int)webBrowser.InvokeScript("execScript");
//mshtml.HTMLDocument webDocument = (mshtml.HTMLDocument)webBrowser.Document;
mshtml.HTMLScriptElement script = (mshtml.HTMLScriptElement)doc.createElement("script");
script.setAttribute("type", "text/javascript");
script.innerHTML = "function doSomething(){ /* do something here... */ }";
//add script to the head
dynamic head = doc.getElementsByTagName("head")[0];
head.appendChild(script);
mshtml.HTMLBody body = (mshtml.HTMLBody)doc.getElementsByTagName("body")[0];
body.style.background = "yellow";
//set any body.style property here...
webBrowser.InvokeScript("doSomething");
That's about it as far as WPF is concerned.

Layer relative positon to background, width and hight

Hi All
I have a problem in Photoshop:
I have a layered image and I wanted to know the relative position of the layer to the background and the width and hight. Does Photoshop allow that?
I know you can get the position by moving the mouse cursor to the top left corner of the layer or by converting the layer to a selection.
This is not a solution for me. I need to know the relative position of the layer while moving it with the "Move Tool". And I also need the width and hight of the layer
Is this possible?
Thanks a lot
Edgar

If You set the Ruler Units in the Info Palette Options to percent and select the Layer with the Move Tool and without any selection active hit command T to move the layer content the Info Palette will show the width, height and position (of the upper left corner) of that layer.
The Options Bar Position Numbers unfortunately dont seem to be expressable as percent values and Width and Height can be entered only as percentages of their original values and not as percentages relative to the files size.
Does that help?

Perspective 3D width and height (stage relative values) in Actionscript

Hello!
I have a small square movieclip in Stage, 100x100 width and height.
I translated it 90º in Y axis. Then, it looks like almost a vertical line.
I want to know the "Perspective 3D width" and "Perspective 3D height" values (something like 24x120 as the rotated square now looks like almost a vertical line).
These values are shown in the movieclip properties, in "3D position and view".
I put an image showing where the values appear. Does anyone know how I access the values via Actionscript?
Thank you!

Hello!
Thanks for the feedback.
After your answer, I searched for an hour to find the relation between matrix3D, transform, and the width and height properties. But I couldn't find the answer in there (I already had tried to search there before posting here).
Maybe the answer can be there too, but "por casualidad" now I just found the solution using this piece of code:
myMc.getBounds(root).height;
myMc.getBounds(root).width;
It solved the problem after 3 hours trying to find the solution! \o/
Thanks for your attention!

How to change the width and height of the visible part of the of the report

I have define a report with paper size 'Letter', orientation 'landscape' and 30 columns. Dynamically I am changing width of columns and suppressing many columns of the report.
Mostly using first 16-20 columns and others get suppressed.
Now problem is that when navigating the report thru crystal viewer, a huge blank spaces getting display on right of the report. When we take jump to some part of report thru navigation tree, the whole report gets shifted to left and only blank part is visible and it is required to scroll left.
Even printing is not working correctly.
Is there any way to change the width and height of the visible part of the report in the viewer thru .net classes? Setting the width and height of the report in Load event handler doesn't help.
Example: CrystalReportViewer1.Width = 200; - is not helping.
Is there any other solution?
Please let me know.
Thanks
Mahesh Patel

Hi Yogesh,
Your suggestion 'reportDocument.PrintOptions.PaperSize=PaperSize.PaperLedger;' along with 'PaperOrientation' setting as follow works fine. I tried to switch between Landscape and Portrait depending on report width.
reportDocument.PrintOptions.PaperOrientation = PaperOrientation.Landscape;
But problem with crystal viewer remain as it is.
While navigating report thru crystal viewer, when we take jump to some part of report thru navigation tree, the whole report gets shifted to left and it is required to scroll left.
Thanks for your very good suggestion.

Prob with fixed column widths and word wrapping in viewer

i have a report where each record has a very long paragraph of text in it.
In desktop and plus, the text column is at a fixed width and the text just wraps nicely according to the column width.
But in Viewer, the column widths do not stay fixed, the text does not wrap, and the long text is displayed in a single line that completely stretches the column width off the page and requires a horizontal scroll bar.
is there anyway to fix the column width in viewer, have the text naturally wrap, and prevent the column stretching. All word wrapping settings are on, but seem to have no effect. I can't seem to find any solution to this.
Thanks...

Hi Pritam,
Per my understanding that you can't see the vertical scrollbar of the ReportViewer controls 2012 to scroll for the grid rows, but can see the vertical scrollbar of the web application, you also can't fix the headers while scrolling, right?
I have tested on my local environment and can't reproduce your issue, but you have an alternative way to add some css to the web form's source code to display the vertical scrollbar.
Details information below for your reference:
Please check below properties setting of the reportviewer which control the visibility of the scrollbar:
AsyncRendering="true"
SizeToReportContent="false"
Please check if this problem also occur on other version of IE and other type of browser.
Please check if you have done correct setting of the Fix data to freeze the table header as the step of below:
http://technet.microsoft.com/en-us/library/bb934257(v=sql.100).aspx
If step1 doesn't work, please click the source of webform.aspx and add below CSS to add the vertical scrollbar manually:
#ReportViewer1 {
overflow-y: scroll;
Run the application you will see it display as below:

How do I stop the Google Search Box from opening and scrolling down when I use the PGDN key?

On My Home Page (Earthlink) - when I use the PGDN (or the down arrow) key to navigate - the google search box opens and scrolls down through recent searches. I really want to just scroll down the home page as I did in the past.
How do I fix?

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that turns off some settings and disables most add-ons (extensions and themes).
''(If you're using an added theme, switch to the Default theme.)''
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu by clicking on the '''Restart with Add-ons Disabled...''' menu item:<br>
[[Image:FirefoxSafeMode|width=520]]<br><br>
If Firefox is not running, you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
''Once you get the pop-up, just select "'Start in Safe Mode"''
[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''

100% percent width AND 100% height rectangles.

Muse should be able to have a rectangle with an image in it scaled to 100% width and height so if my browser goes full screen, the rectangles adjust to it.
No I am not talking about a Pinned rectangle sidebar menu. I am talking about rectangles on the page that contain images with a 100% width.
Muse should be able to have MULTIPLE 100% height rectangles, so as you scroll, each section with a 100% width and height rectangle adjusts to your browser size.
To see the desired effect, check out this site.
http://www.schlage.com/en/home/keyless-deadbolt-locks/touch.html

Thats right ...
there is no provision of defining percentage of ALV grid.
it takes the size of contianer automatically....
Though you can try dynamic screen generation. but i am not sure if it allows you to determine user's screen resolution and size.
As all the processing is done on Applicaition serer this doesnt makes any sense.
So u have to stick to old style programming and Static ALV grid size
Hope this helps you.

Yes I have removed and reinstalled WMP.
I had good results with the PD6 application installed on the default path onto the C: drive with the one exception that if the application was launched by accident and the user data path was not available, the PD6 application would blow away my custom user path registry settings. Now that I know what they are I have made a .reg file to repair my registry to my desired user data paths.
Installing the application on the removable drive appeared to help prevent me from launching the application by accident and overwriting my registry with default user paths.
So which is the less of the two evils?
If the application directory is not available, windows media player still tries to launch the .msi for installing PD6.
If I install the application to the C: drive but the user data to the removable drive, launching the PD6 application without the user data drive will still corrupt my registry settings for a user data path.
Both these issues seem like a logical (if not easy) fix that should be done in the PD6 application and installation package. I mean really, cannot anyone tell me why windows media player is checking the PD6 application directory? Why in PD4 did we have an option control for setting the user data path from the PD4 application? Why is this option not in the PD6 application, just the installer?
I am given a choice during installation to move the user data to another non default location. Why else would this be provided if not to accommodate my kind of request to store the user data into an alternate location other than “My Document”. Certainly Palm is not trying to force the users on how to protect and store their personal data?

JTabbedPane: Tab Text, Tab Width and Tab Height

Whenever i put text on JTabbedPane tab it displays it in one line, so when i have a text e.g. "XXXXXXXXX XXXXXXXXX"
it displays it as it is not like XXXXXXXXX
XXXXXXXXX
How can I display it in two line or more?
Does Tab width and height automatically adjust itself relative to the text inside it? If not how can I set the tab width and height?
Thanks in advance.

leemax quote:
Simply add the escaped new line character "\n" to display the text of the tab on the next line.
--Yeah i tried that already but anyway i solved the problem by making used of htnl tags "<br>"

SWFLoader.content: stage width and height, can i override to return proper results ?

Hiya.
I'm loading with SWFLoader games that where written using stage functions to get the width and height of the stage and to draw the game and calculate game movements accordinly. When I load a game using SWFLoader, the stage size changes from the stage size of the flash application that i loaded with SWFLoader to the stage size of my entire flex application with breaks the loaded flash application.
is there a way to override the stage related functions in the loaded flash application in order for them to return the proper value ?
if my flash application is width=50px height=50px and it's located at my flex stage at x=20px width=20px,
then the width and height of the stage of the flash application will return 70px.
is there a way to resolve that ?

If an app has dependencies on stage size, it will not behave well as a
sub-app.

Pavilion dv4-1275mx notebook - once-flashing leds @ caps lock and scroll keys @ start-up

My HP Pavilion dv4-1275mx notebook runs Windows Vista Home Premium service pack 1 for 64x-based systems.
Recently, when I turn it on, the led lights @ the caps lock and scroll keys repeatedly flash once.
I'm not sure what, if anything, happened prior to this starting. It's possible that there was a power surge when it was shut off, or it may be related to doing a McAfee virus scan or installing the latest version of a software, e.g., Adobe Reader.
I was able to use my System Recovery disks to reinstall the Vista software, thinking this might "kickstart" my computer into working, e.g., as part of the restart process. After the reinstallation, I was able to use my computer, although the led lights continued to flash. However, once I shut down my computer, I have been unable to restart it. The leds continue to flash upon start-up, and I have not been successful in again reinstalling the Vista software. (I thought if could get my computer to work again that way, it might stay accessible if I used hiberate mode instead of shutting it down.)
The computer's about 4-1/2 years old. The screen has a short of some kind (only turning on when the screen is low to the keyboard, so I use an external monitor.

Try the steps in the following weblink:
