• Retrieve selected elements in GeckoWebBrowser

  - by Mostafa Mahdieh

  I am using GeckoFX version 1.9.1.0 with C#.NET. I have a placed a GeckoWebBrowser Component (geckoWebBrowser1) and a Button (button1) in a form and have navigated the browser to a page. Some text in the page can be selected. This text is composed of one or more DOM elements. When button1 is clicked, I want to retrieve the DOM elements that compose the selected text in the page and give an id to one of those elements and save add these ids to a list (in C# space). How can I do this?

• Default Values in XForms Input

  - by Josh

  I have an XForm that has certain fields that may often be left blank (optional street address). Is there is technique to set a default value for that field, preferably a space (I am running into weird formatting issues with CSS). The html form way of value="" doesn't work, neither does setting a default value in the XML schema. EXAMPLE: <xforms:input ref="clientaddress/streetaddress2" model="model_inventory" > <xforms:label>Street Address (Line 2)</xforms:label> Leaving this field blank results in <streetaddress2/> in the resulting xml document I want <streetaddress> </streetaddress>

• Huge dataset point in polygon in .net (collision detection)

  - by Rickard Liljeberg

  I have a pretty big mesh with polygons, usually triangles but sometimes rectangles. Each point in my mesh has a value (value has nothing to do with coordinates). Now I am creating a second mesh in the same coordinate-space as the old mesh. I now want to interpolate out values for all points (vertices) in the new mesh using the values from the old mesh. Now I could loop each polygon in the new mesh and detect which old vertices are in each polygon by making 2d collision detection (altho even this I don't get to function properly so if anyone has simple and fast code for 2d collision detection (triangle is enough) I would gladly see it). However to my main point again. looping each old vertice for each new polygon seems less than efficient. is there a better way?

• LNK1106 with big binary resource

  - by E Dominique

  I have a rather huge .dat-file (896MB) included as a BIN resource in my project. Now I get a LNK1106 link error ("fatal error LNK1106: invalid file or disk full: cannot seek to 0x382A3920".) I use Visual Studio 2005 under Windows XP, and have tried on a 4GB RAM machine with high Virtual Memory settings and lots of disk space. I have tried a number of different optimization flags, but to no avail. Does anyone have a clue? EDIT: I have narrowed it down to a specific size of the compiled resource. If the .res file is 544078588 bytes (about 518.9MB) or larger, the error occurs. If it is smaller it works just fine. Still no solution, though...

• Extracting a string starting with x and ending with y

  - by DMan

  First of all, I did a search on this and was able to find how to use something like String.Split() to extract the string based on a condition. I wasn't able to find however, how to extract it based on an ending condition as well. For example, I have a file with links to images: http://i594.photobucket.com/albums/tt27/34/444.jpghttp://i594.photobucket.com/albums/as/asfd/ghjk6.jpg You will notice that all the images start with http:// and end with .jpg. However, .jpg is succeeded by http:// without a space, making this a little more difficult. So basically I'm trying to find a way (Regex?) to extract a string from a string that starts with http:// and ends with .jpg

• How would I / could I obtain an reasonably comprehensive list of domain names?

  - by Simon

  I know that domain names are constantly changing, and I know there are a lot of them, but there is clearly a region of the domain name space which is stable. How would I go about getting a list, even a very big one? Such a thing must logically exist, even if it is in a distributed form, because the web's DNS servers resolve names to IP addresses. So in theory if I could poll all the DNS servers in the world at a moment in time I would have the complete list of mapped names. Is there a practical way of doing that? As an aside, does anyone have any good estimates of how many domain names exist at the moment?

• How can I force my checkbox's text to not wrap?

  - by B. Clay Shannon

  This is what my LinearLayout (horizontal) row looks like: I want the text of the checkbox to be on one line; The buttons don't have to be that wide - they'll still have plenty of space with the checkbox text lengthened a bit. What in my XML: <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <CheckBox android:id="@+id/ckbxAllow_New_Items" android:layout_width="0dip" android:layout_height="fill_parent" android:layout_weight="1" android:checked="true" android:text="@string/checkbox_Allow_New_Items" /> <Button android:id="@+id/btnOK" android:layout_width="0dip" android:layout_height="wrap_content" android:layout_weight="1" android:text="@string/button_OK" /> <Button android:id="@+id/btnCancel" android:layout_width="0dip" android:layout_height="wrap_content" android:layout_weight="1" android:text="@string/button_Cancel" /> </LinearLayout> ...needs to change in order to force my checkbox text not to wrap? UPDATE Following Der Golem's suggestion by adding this: android:lines="1" ...and also changing layout_weight for the checkbox from 1 to 2 (set to 1 for the buttons) gave me what I wanted:

• How to put a newline into a column header in an xtable in R

  - by PaulHurleyuk

  I have a dataframe that I am putting into a sweave document using xtable, however one of my column names is quite long, and I would like to break it over two lines to save space calqc_table<-structure(list(RUNID = c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L), ANALYTEINDEX = c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L), ID = structure(1:11, .Label = c("Cal A", "Cal B", "Cal C", "Cal D", "Cal E", "Cal F", "Cal G", "Cal H", "Cal High", "Cal Low", "Cal Mid"), class = "factor"), mean_conc = c(200.619459644855, 158.264703128903, 102.469121407733, 50.3551544728544, 9.88296440865076, 4.41727762501703, 2.53494715706024, 1.00602831741361, 199.065054555735, 2.48063347296935, 50.1499780776199), sd_conc = c(2.3275711264554, NA, NA, NA, NA, NA, NA, 0.101636943231162, 0, 0, 0), nrow = c(3, 1, 1, 1, 1, 1, 1, 3, 2, 2, 2)), .Names = c("Identifier of the Run within the Study", "ANALYTEINDEX", "ID", "mean_conc", "sd_conc", "nrow"), row.names = c(NA, -11L ), class = "data.frame") calqc_xtable<-xtable(calqc_table) I have tried putting a newline into the name, but this didn't seem to work names(calqc_table)[1]<-"Identifier of the \nRun within the Study" Is there a way to do this ? I have seen someone suggest using the latex function from the hmisc package to manually iterate over the table and write it out in latex manually, including the newline, but this seems like a bit of a faf !

• ruby on rails state machines

  - by srboisvert

  I'm looking to implement a state machine to manage a user moving through a series of steps over an extended period of time (weeks) with emails and then they interact with the app. I've looked at a couple of AASM plugins and forks (it seems like this plugin space has become a bit chaotic) and am curious what people would recommend. I saw the automatic AASM by hashrocket, that transitions states using cron, and from the title it looks like it might fit the bill but there doesn't appear to be any documentation anywhere and it looks more like a skeleton app than a plugin.

• Scala/Erlang use something like greenThread or not ?

  - by CHAPa

  Hi all, Im reading a lot about how scala/Erlang does lightweight threads and your concurrency model ( Actor Model ). Off course, some doubts appear in my head. Scala/Erlang use a approach similar to the old thread model used by java (greenThread) ? for example, suppose that there is a machine with 2 cores, so the scala/erlang environment will fork one thread per processor ? The other threads will be scheduled by user-space( scala VM / erlang vm ) environment. is it correct ? how under the hood that really work ? thanks a lot.

• Silverlight project builds in VS2008 but fails when using MSBuild

  - by Tom

  Hi, We have 2 Silverlight projects in the same solution; SLGlobalResource and SLData. SLData references SLGlobalResource (using references add reference projects). When we build it in debug within VS2008, everything builds fine and all is good. But when we build it using: msbuild TheSolution.sln /p:Configuration=Debug /t:rebuild SLData fails with the following error: ViewModels\ImportViewModel.cs : error CS0246: The type of name space "SLGlobalResource" could not be found (are you missing a using directive or an assembly reference?) This also happens in TeamCity (I guess because the TeamCity vs2008 runner uses MSBuild) Any ideas? Thanks Edit: There are actually 33 projects in total in the solution. I didn't think this was relevant before but now I'm thinking it could be - could this be a build order thing?

• Super wide, but not so tall, bitmap?

  - by Erik Karlsson

  Howdy folks. Is there any way to create a more space/resource efficient bitmap? Currently i try to render a file, approx 800 px high but around 720000px wide. It crashes my application, presumebly because of the share memory-size of the bitmap. Can i do it more efficient, like creating it as an gif directly and not later when i save it? I try to save a series of lines/rectangles from a real world reading, and i want it to be 1px per 1/100th of a second. Any input? And btw, i never manage to ogon using google open id : /

• HTML 5: Is it <br> <br/> or <br />?

  - by Eikern

  I've tried checking other answers, but I'm still confused--especially after seeing W3schools HTML 5 reference. I thought HTML 4.01 was supposed to "allow" single-tags to just be <img> and <br>. Then XHTML came along with <img /> and <br /> (where someone said that the space is there for older browsers). Now I'm wondering how I'm supposed to format my code when practicing HTML 5. <!DOCTYPE HTML> Is it <br>, <br/> or <br />?

• Looking for Eclipse plugin: Lock source tabs in place

  - by Fredrik

  When working with java code in Eclipse I can typically juggle between 20-40 different files, but there usually are just two that I actively work with at the time (test and code). Going back to the code where I want to work after having debugged through 5-10 classes can be a pain. So what I would like to do is to be able to right click on the tab of a class and choose to lock them in place. The classes would then always be available as the first and second tabs furthest to the left in the editor. All other classes (and other files opened in the editor) would then fight over the remaining space in the editor like today. Is there a plugin like this? My google-fu might not be strong enough, cause I find nothing.

• How to Filter more than one field using WPF AutoCompleteBox

  - by Drew

  i am trying to customize the suggestions on the AutoCompleteBox in the WPF Tool kit. Right now i have a last name field which when the user enters characters a query runs that retrieves the top 10 records based on that last name. i would also like to filter by first name, i tried splitting out the comma and searching by the last name and the characters entered in the first name. however, as soon as a space or comma is entered into the autocompletebox, the suggest functionality stops working, which I believe is because the ValueMemberPath property is set to be last name. Is there a work around for this, or a way to modify the ValueMemberPath to handle multiple values? Thanks!

• Regex Problem in PHP

  - by Chris

  I'm attempting to utilize the following Regex pattern: $regex = '/Name: [a-zA-Z ]*] [0-9]/'; When testing it in Rubular, it works fine, but when using PHP the expression never returns true, even when it should. Incidentally, if I remove the "[0-9]" part, it works fine. Is there some difference in PHP's regex syntax that I'm overlooking? Edit: I'm looking for the characters "Name:" then a name containing any number of letters or spaces, then a "]", then a space, then a single number. So "Name: Chris] 5" would return true and "Name: Chris] [lorem ipsum]" should return false. I also tried escaping the second bracket "\[" but this did not fix the problem.

• how to better use of eclipse code templates (PHP)?

  - by pocketfullofcheese

  One particular problem I was having was using ${word_selection} in an Eclipse PDT template. I was recently trying to use some code templates with Eclipse PDT 2.1 to speed up some common tasks. We use a lot of getters/setters, so I wrote the following template. function get${word_selection}() { return $$this->getData('${word_selection}'); } function set${word_selection}($$${word_selection}) { $$this->setData('${word_selection}', $$${word_selection}); } I named the template "getset" and the only way I know to use the Code Assist is to type: "getset" then hit my code assist keys (I have it set to Esc, but I think the default was Ctrl+Space). The problem is, this doesn't actually let me select a word to be used by the ${word_selection}. how do I type in my template name, hit the key combo, and have a word selected all at the same time? I also want to know what kinds of templates people have set up and any other tips for using templates to speed of programming.

• Process Memory limit of 64-bit process

  - by prakash

  I currently have a 32-bit .Net application (on x86 Windows) which require lots of memory. Recently it started throwing System.OutOfMemoryException's. So, I am planning to move it to a x64 platform as 64-bit process. So will this help with the out of memory exceptions. I was reading this article from MSDN Memory limits for Windows So, my question is if I compile a 64bit .Net application, will it have IMAGE_FILE_LARGE_ADDRESS_AWARE set as default (As the article suggests)? i.e will I be able to take advantage of the 8GB user-mode virtual address space?

• How to create a rounded title border in Java Swing

  - by Stephane Grenier

  I do understand that to create a title border, you do something like: BorderFactory.createTitledBorder(" Your Title "); However this creates a rectangle border whereas I need a rectangle with curved corners. Now from what I understand you can create your own custom border by: class CustomBorder implements Border { ... } The problem is that I'm not sure how to write the code that overrides the method: public void paintBorder(Component component, Graphics g, int x, int y, int width, int height) Or better yet, is there a way to do it without implementing your own Border class? And if not, how would you write that custom Title Border? I'm ok with drawing a rectangle with rounded corners, but how do you do it so that there's space for the label too?

• Why does installing NVidia 9600GT graphics card, take 1GB of RAM away from Windows?

  - by Nick G

  Hi, I've changed graphics cards in my PC and now Windows 7 (32bit) is reporting that I have a whole gigabyte less physical RAM in my PC. Why is this? Firstly, the machine has 4GB of physical RAM. The old card was an ATI 2600XT with 256MB and the new card is an NVidia 9600GT with 512MB. With the ATI card windows sees 3326MB. With the NVidia card, windows sees 2558MB. I realise that due to address space restrictions I will not see all 4GB with 32bit windows, but why is there such a massive loss of RAM when simply changing cards (bearing in mind BOTH cards have their own RAM and borrow no main memory like some built on chipsets do). Would using 64 bit windows solve this? Thanks Nick.

• Edit a video to embed a bitmap.

The size of the bitmap is about the size of a channel logo and that is exact space it will occupy in the video. Please guide me in accomplishing. Is there any existing libraries available to do this.

• How to achieve Bing maps like InfoWindow in Google Maps?

  - by BillB

  I'm using Google Maps v3. I really like the InfoWindows found in Bing, as opposed to Google. Screenshots & functionality found here comparing the two: http://www.axismaps.com/blog/2009/07/data-probing-and-info-window-design-on-web-based-maps/ Question: How can I replicate Bing like InfoWindows while using Google Maps v3? UPDATE: To be more specific, what I like about Bing's InfoWindows include: - The pointer dynamically changes sides from left/right/bottom/top, as opposed to Google limited to only have the InfoWindow pointer on the bottom - Bing's InfoWindows use less space - You can configure Bing's InfoWindows to pop up outside of the map bounders so that you don't have to autopan the map to display the marker's InfoWindow

• how do I get the height of a rich text content after word wrap?

  - by Led

  Question A. Given 1. A string in rich text format that may have paragraph, tabs, space, line break, indentation, (or even image?) 2. A width for the word wrapping rich text control/editor How do I know the height of the content after it have performed all the word wrapping? Is there something like int MeasureRichTextHeightAfterWordWrap(string aRichTextContent, int aWidth)? Otherwise how does those rich text control know how much to autosize? Do I have to actually place the content on a dummy rich text control and get its height afterwards? Question B. Similar to question A but in plain text onto a plain text memo/control/editor. And manually draw string with manually calculated indentations, breaks, word wrappings. Is it easier or harder?
