• Dual slider control with custom skin

  - by Ryan French

  Hi All, I'm currently trying to create a page for users to select two points from a range, using a slide control. The first point in the range is when an alert will be sent to the user, the second point is a max limit. What I would like to do is have the bar colored green from the 0 point to the first slider point, then orange between the two sliders, and lastly red from the second slider up to the other end of the bar. Does anyone know of an easy was I can do this or of a slider control that can be skinned to do this?

• Removing all Matching Classes in jQuery

  - by Seth Duncan

  Hi I have an li element that will have something along the lines of this for a declaration <li class="module ui-helper-fix"> And I can dynamically change the color of the module by adding on classes (That are provided dynamically through DB calls) the end result being <li class="module ui-helper-fix module-green"> or <li class="module ui-helper-fix module-default"> Well I am fine with changing the color by adding on a new module-WHATEVER class but what I would like to do is remove any class that matches module-XXXX so it starts with a clean slate and then add on the class module-crimson. So how do I remove all classes that match module-xxx first ? Keeping in mind I don't want to remove the base module class. Thanks. -Seth

• Objective-C : enum like Java (int values and many others for each enum)

  - by Oliver

  In Java, you can make an enum having multiples values. In objective-C, this cannot be done easily. I've read many pages about this but I didn't found anything satisfying that would allow me to use enums by a simple way and to keep the enum declaration and their different values in the same file. I would like to write something like this in a enums.h : // ======================================== typedef enum {eRED, eGREEN, eBLUE} ColorEnum; int colorValues[] = { 0xFF0000, 0x00FF00, 0x0000FF }; NSArray *colorNames = [NSArray arrayWithObjects:@"Red color", @"light green", @"Deep blue", nil]; // ======================================== and be able to use thoses global variables to manage my stuff anywhere like : int color = colorValues[eRED]; But I don't know how to write this. I have compile errors like "ColorValues" is defines many times. Or if I just use "static", I have many "ColorValues" not used in .m file... Could you help me ?

• CSS border and the :hover dynamic pseudo-class

  - by dbasch

  Hi All, I have built a persistent dropline menu with two levels using only CSS. It is pretty standard. It is a nested set of UL's and the UL's :hover state is what shows and hides the sub menu levels. Something like this: | *Pets* | Colors | Cars | | Cats | Dogs | Birds| Goats | Sheep | | Pets | *Colors* | Cars | | Red | Orange | Green | Blue| Yellow | I then added a 1px border at the bottom of the first level UL element. Like this: | *Pets* | Colors | Cars | -------------------------------------- | Cats | Dogs | Birds| Goats | Sheep | When I hover over a first level item (Pets), and then move the mouse down to the second level (Cats), the entire second level disappears. I finally figured out that the UL's 1px border is not included in the hover area for the UL. Can I add a border to the bottom of a dropline menu level without messing up the menu hovering? Thanks!

• iPhone switch statement using enum

  - by Boris

  I have defined an enum in a header file of a class : typedef enum{ RED = 0, BLUE, Green } Colors; - (void) switchTest:(Colors)testColor; and in the implementation file I have : - (void) switchTest:(Colors)testColor{ if(testColor == RED){ NSLog(@"Red selected"); } switch(testColor){ case RED: NSLog(@"Red selected again !"); break; default: NSLog(@"default selected"); break; } } My code compiles correctly without warrnings. When calling the switchTest method with RED, the output is : "Red selected" but once the first line of the switch runs, the application quits unexpectedly and without warrnings/errors. I don't mind using if/else syntax but I would like to understand my mistake.

• Regex: Strip HTML attributes except SRC

  - by Ian Silber

  Hi, I'm trying to write a regular expression that will strip all tag attributes except for the SRC attribute. For example: <p id="paragraph" class="green">This is a paragraph with an image <img src="/path/to/image.jpg" width="50" height="75"/></p> Would be returned as: <p>This is a paragraph with an image <img src="/path/to/image.jpg" /></p> I have a regular expression to strip all attributes, but I'm trying to tweak it to leave in src. Here's what I have so far: <?php preg_replace('/<([A-Z][A-Z0-9]*)(\b[^>]*)>/i', '<$1>', '<html><goes><here>'); Using PHP's preg_replace() for this. Thanks! Ian

• How do you fix the Silverlight application shift that occurs in the Firefox browser?

  - by Roy

  Hi, Currently I have an Silverlight application that when run on Firefox browser (ver 3.6) the entire contents of the Silverlight application shifts a little, and also the scrollbars on both the bottom and the side appear when I first use it. This does not happen in IE 8. How can I fix this in Firefox so it doesn't happen? The project type I created was the "Silverlight 3 Application + Website" via Expression Blend 3. This the code I am using in my MainPage.xaml: <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="StackoverflowExample.MainPage" Width="640" Height="480"> <Grid x:Name="LayoutRoot" Background="Green"> <Rectangle Fill="#FFBB2020" Stroke="Black" Margin="155,58,266,178"/> <Button Margin="199,180,302,236" Content="Button"/> </Grid> </UserControl>

• Eidetic memory: What magic numbers you still remember?

  - by Hao

  Long before you practice writing readable code, what "magic numbers" you still remember up to this day? here's some of my list: 72 80 75 77 13 32 27 - up down left right enter space escape 1 2 4 128 - blue green red blink 67h 33h 17h - interrupt for EMS, mouse, printer function AH 9, interrupt 21 alt+219 for block ASCII alt+164 ñ 90 NOP 13 10 carriage return, line feed ascii 1 and 2 face, ascii 3 heart. no not this heart: <3 :-) debug -o72,10 -o71,12 clears the BIOS password. I don't know what those numbers mean, it's like a trade secret that gets shared with each other during college days. ascii 7 sounds a beep P.S. Somehow, remembering some of these magic numbers can help you in some tech problems, your keyboard is broken, the office pal's keyboard doesn't have accented characters. An anecdote, during college, one of my friend asked me how to remove the newlines in his Word document. Not having used Word so much then, I somehow "intuitively" guessed to find ^013 and replace it with blank. Well it works :-)

• Double associative array or indexed + associative array

  - by clover

  I'm undecided what's the best-practice approach for what I'm trying to do. I'm trying to enter data into an array where the data will look like this: apple color: red price: 2 orange color: orange price: 3 banana color: yellow price: 2 pineapple color: yellow price: 5 When I get input, let's say green apple (notice it's a combo of color + name of fruit), I'm going to check if the name of fruit part exists in the array and display its data (if it exists). What's the right way to compose those arrays? How would I do an indexed array containing an associative array? (or would this be better as 2 nested associative arrays, I'm guessing not)

• How does Bitmap.Save(Stream, ImageFormat) format the data?

  - by Matt Jacobsen

  I have a non transparent, colour bitmap with length 2480 and width 3507. Using Bitmap.GetPixel(int x, int y) I am able to get the colour information of each pixel in the bitmap. If I squirt the bitmap into a byte[]: MemoryStream ms = new MemoryStream(); bmp.Save(ms, ImageFormat.Bmp); ms.Position = 0; byte[] bytes = ms.ToArray(); then I'd expect to have the same information, i.e. I can go to bytes[1000] and read the colour information for that pixel. It turns out that my array of bytes is larger than I anticipated. I thought I'd get an array with 2480 x 3507 = 8697360 elements. Instead I get an array with 8698438 elements - some sort of header I presume. In what format the bytes in my array stored? Is there a header 1078 bytes long followed by Alpha, Red, Green, Blue values for every byte element, or something else?

I deleted those CVS\ folders and they are showing up (as unversioned files) when I CheckIn. Any ideas?

• poblems with jquery code

  Another jquery issue... I have tried this several times using "class" and "id" elements and I can not get it right. I am hoping the brains on stackoverflow can help!

• How do I draw an ESB on a SoaML diagram?

  - by dave

  I've recently had to draw some architectural diagrams that feature the use of an Enterprise Service Bus. The ESB is critical, so everyone wants it to show up on the diagram. But since it's the center of what everything is connected to, it really of gets in the way. I settled on trying to use SoaML. I color-coded the request points blue and service points green, to help then stand out. The text names on the ports give you a sense of what talks to what, and it's incredibly obvious that everything goes through the ESB. Can anyone comment on my approach? Any suggestions on something better?

• How do I create regex groups for replacement?

  - by resting

  I have this sample string: Image: SGD$45.32 SKU: 3f3f3 dfdfd grg4t BP 6yhf Pack Size: 1000's Color: Green Price: SGD$45.32 SGD$45... I would like to remove all the prices namely: SGD$45.32 Price: SGD$45.32 SGD$45 I have this expression thats supposed to match the 3 groups: $pattern = '/(Price.+\sSGD\$\d+\.\d{2})(SGD\$\d+\.\d{2})(SGD\$\d+)/'; $new_snippet = preg_replace($pattern, '', $snippet);` But apparently its not working. It works if I replace a single group at a time. But, I'd like to know if it possible to replace all possible matching groups with a single statement. Tried preg_match_all($pattern, $snippet, $matches); to show matches based on the above pattern, but no matches are found if I put all 3 groups together.

• In eclipse, how can I create a shortcut for an existing command that has no shortcut binding in the

  - by Visus Zhao

  In eclipse, the behavior of Ctrl+F11 is determined by preference config, and you could have either "Run last launch in history" or "Run current resource/editor" option available. But I'd like to have both of them at the same time, with an additional shortcut (e.g. Alt+F11). But eclipse doesn't provide the two commands in "key preference". Can I create a new shortcut that links to the "Run last launched" or "Run current editor"? It'd be even better if i could make a shortcut to show the launch history(the arrow beside the green little run button) Is this possible? could anyone give a quick hint on where to find resources to implement it? P.S.: Maven plugin's "Add dependency" common is another good candidate.

• Change write-host output color based on foreach if elseif outcome in Powershell

  - by Emo

  I'm trying to change the color of write-host output based on the lastrunoutcome property of SQL Server jobs in Powershell....as in...if a job was successfull, the output of lastrunoutcome is "Success" in green....if failed, then "Failed" in red. I have the script working to get the desired job status...I just don't know how to change the colors. Here's what I have so far: # Check for failed SQL jobs on multiple servers [reflection.assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo") | out-null foreach ($svr in get-content "C:\serverlist2.txt") { $a = get-date $BegDate = (Get-Date $a.AddDays(-1) -f d) + " 12:00:00 AM" $BegDateTrans = [system.datetime]$BegDate write-host $svr $srv=New-Object "Microsoft.SqlServer.Management.Smo.Server" "$svr" $srv.jobserver.jobs | where-object {$_.lastrundate -ge $BegDateTrans -and $_.Name -notlike "????????-????-????-????-????????????"} | format-table name,lastrunoutcome,lastrundate -autosize foreach ($_.lastrunoutcome in $srv.jobserver.jobs) { if ($_.lastrunoutcome = 0) { -forgroundcolor red } else {} } } This seems to be the closest I've gotten...but it's giving me an error of ""LastRunOutcome" is a ReadOnly property." Any help would be greatly appreciated! Thanks! Emo

• Form.ShowDialog() does not show form.

  - by clawson

  I've come across a situation where I try to run a simple line of code in a method Dim res As DialogResult = frmOptions.ShowDialog() but nothing happens. The dialog box will not appear. If I run this method from another location in the code it executes fine (i.e. displays the form in dialog mode and code executes fine thereafter). Hence, it may be the way in which I arrive at this code that is causing my problem, but I cannot see to find what is wrong. When I pause the debugger the line of code is highlighted in green but I can't see to step over it or into it. Any idea what may cause this to happen, or what I should be looking for that might be causing the problem?? Thanks for the help!

Header is highlighted with blue. You can see that "LAME3.96" text is highlighted with green. What does it does there? Is this a part of MP3 elementary stream? Or this is the part of some headers I didn't tag?

• iPhone Map: Identifying Users Location

  I have a number of annotations on my map, in addition to the users current location. This works fine, except the default color for the users current location is the same as all of the other annotations. I'd like to make the pin green for the users current location so that it's uniquely identifiable from the other pins. How do I do this? Bellow is the method I've been using (I can't find a way to determine which annotation is the users current location): - (MKAnnotationView *)mapView:(MKMapView *)mapViewLocal viewForAnnotation:(id <MKAnnotation>)annotation { static NSString *identifier = @"Pin"; MKPinAnnotationView *pinView = (MKPinAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:identifier]; if (pinView == nil) { pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier] autorelease]; pinView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; pinView.animatesDrop = YES; pinView.canShowCallout = YES; } else { pinView.annotation = annotation; } return pinView; }

• Multiple CSS Classes: Properties Overlapping based on the order defined.

  Is there a rule in CSS that determines the cascading order when multiple classes are defined on an element? (class="one two" vs class="two one") Right now, there seems to be no such effect. Example: both divs are orange in color on Firefox <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <style> .one { border: 6px dashed green } .two { border: 6px dashed orange } </style> </head> <body> <div class="one two"> hello world </div> <div class="two one"> hello world </div>

• Most efficient way to save tile data of an isometric game

  - by Harmen

  Hello, I'm working on an isometric game for fast browsers that support <canvas>, which is great fun. To save information of each tile, I use a two-dimensional array which contains numbers representing a tile ID, like: var level = [[1, 1, 1, 2, 1, 0], [0, 1, 1, 2, 0, 1], [0, 1, 1, 2, 1, 1]]; var tiles = [ {name: 'grass', color: 'green'}, {name: 'water', color: 'blue'}, {name: 'forest', color: 'ForestGreen'} ]; So far it works great, but now I want to work with heights and slopes like in this picture: For each tile I need to save it's tile ID, height and information about which corners are turned upward. I came up with a simple idea about a bitwise representation of all four corners, like this: 1011 // top, bottom and left corner turned up My question is: what is the most efficient way to save these three values for each cell? Is it possible to save these three values as one integer?
