• SEO Friendly URL Rewriter Parameters

  - by Kristen

  I would appreciate you advice on how to incorporate parameters into SEO Friendly URLs We have decided to have the "techie" parameters first, followed by the "SEO Slug" \product\ABC123\fly-your-own-helicopter much like S.O. - if the SEO Slug changes, or is truncated, or missing, we still have the Product and ABC123 parameters; various articles say that having such extra data doesn't harm SEO ranking. We need to have additional parameters; we could use "-" to separate parameters as it makes them look similar to the SEO Slug, or we could/should use something else? \product\ABC123-BOYTOY-2\boys\toys\fly-your-own-helicopter This is product=ABC123, in Category=BOYTOY and Page=2. We also want to keep the hierarchy as flat as possible, and thus I think: \product-ABC123-BOYTOY-2\boys\toys\fly-your-own-helicopter would be better - one level less. We have a number of "zones", e.g. \product-ABC123\seo-slug-for-product \category-BOYTOY\seo-slug-for-category \article-54321\terms-and-conditions it would help us a lot if we could just user our 5 digit Page ID number instead, so these would become \12345-ABC123\seo-slug-for-product \23456-BOYTOY\seo-slug-for-category \54321\terms-and-conditions (Products & Categories have a number of different Page IDs for different templates, this style would take us straight to the right one) I would appreciate your insight into what parameter separators to use, and if the leading techi-data is going work well for us. In case relevant: Classic ASP application on IIS7 + MSSQL2008 Product & Category codes contain A-Z, 0-9, "_" only.

• Map tiling - What kind of projection?

  - by ikky

  Hi. I've taken a large image and divided it in to square tiles (256x256). It is made for google maps also, so the whole image is divided into z_x_y.png (Depending on zoom level). z=0 = 1x1 tile z=1 = 2x2 tilesthe z=2 = 4x4 tiles My imageMap is "flat" and is not based on a sphere like the worldmap. I'm gonna use this map on a windows mobile app (which has no google API), and all the "points of interests" is inserted into a database by longitude and latitude. And since i have to make this for the windows mobile, i just have XY coordinate system. Is it enough to just use this: MAP_WIDTH = 256*TILES_W; MAP_HEIGHT = 256*TILES_H; function convert(int lat, int lon) { int y = (int)((-1 * lat) + 90) * (MAP_HEIGHT / 180); int x = (int)(lon + 180) * (MAP_WIDTH / 360); ImagePoint p = new ImagePoint(x,y); // An object which holds the coordinates return p; } Or do i need a projection technique? Thanks in advance. Please ask, if something is unclear.

• CQRS - The query side

  - by mattcodes

  A lot of the blogsphere articles related to CQRS (command query repsonsibility) seperation seem to imply that all screens/viewmodels are flat. e.g. Name, Age, Location Of Birth etc.. and thus the suggestion that implementation wise we stick them into fast read source etc.. single table per view mySQL etc.. and pull them out with something like primitive SqlDataReader, kick that nasty nhibernate ORM etc.. However, whilst I agree that domain models dont mapped well to most screens, many of the screens that I work with are more dimensional, and Im sure this is pretty common in LOB apps. So my question is how are people handling screen where by for example it displays a summary of customer details and then a list of their orders with a [more detail] link etc.... I thought about keeping with the straight forward SQL query to the Query Database breaking off the outer join so can build a suitable ViewModel to View but it seems like overkill? Alternatively (this is starting to feel yuck) in CustomerSummaryView table have a text/big (whatever the type is in your DB) column called Orders, and the columns for the Order summary screen grid are seperated by , and rows by |. Even with XML datatype it still feeel dirty. Any thoughts on an optimal practice?

• An implementation of Sharir's or Aurenhammer's deterministic algorithm for calculating the intersect

  - by RGrey

  The problem of finding the intersection/union of 'N' discs/circles on a flat plane was first proposed by M. I. Shamos in his 1978 thesis: Shamos, M. I. “Computational Geometry” Ph.D. thesis, Yale Univ., New Haven, CT 1978. Since then, in 1985, Micha Sharir presented an O(n log2n) time and O(n) space deterministic algorithm for the disc intersection/union problem (based on modified Voronoi diagrams): Sharir, M. Intersection and closest-pair problems for a set of planar discs. SIAM .J Comput. 14 (1985), pp. 448-468. In 1988, Franz Aurenhammer presented a more efficient O(n log n) time and O(n) space algorithm for circle intersection/union using power diagrams (generalizations of Voronoi diagrams): Aurenhammer, F. Improved algorithms for discs and balls using power diagrams. Journal of Algorithms 9 (1985), pp. 151-161. Earlier in 1983, Paul G. Spirakis also presented an O(n^2) time deterministic algorithm, and an O(n) probabilistic algorithm: Spirakis, P.G. Very Fast Algorithms for the Area of the Union of Many Circles. Rep. 98, Dept. Comput. Sci., Courant Institute, New York University, 1983. I've been searching for any implementations of the algorithms above, focusing on computational geometry packages, and I haven't found anything yet. As neither appear trivial to put into practice, it would be really neat if someone could point me in the right direction!

• Codeigniter: Base_url doesn't seem to be working

  - by Dwayne

  I have developed a simple site that fetches tweets from the Twitter public timeline, caches them for 60 seconds and so on. I have recently moved hosts from Hostgator to Mediatemple and my site was previously working fine on Hostgator. My application doesn't use a database connection, nor does it use any form of flat-file database either. Tweets are cached in an XML file stored in the root directory, not that most of that is important. The url helper is being included as can be seen below (this is my helpers line from autoload.php): $autoload['helper'] = array('url'); I have also removed my index.php file from the URL using .htaccess directives and once again this was previously working on Hostgator (see my .htaccess code below): RewriteEngine On RewriteRule ^(application) - [F,L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule .* index.php/$0 [PT,L] In my home.php view file which is in the views folder inside of application, I am using the function base_url() which was previously working on Hostgator inside of my view files and appending it a base href value in my header: <base href="<?php echo base_url(); ?>" /> Here is what my base_url value looks like in the config.php file: $config['base_url'] = "http://threetune.com/"; Although what appears to be happening is that the base_url is not to be seen at all. It doesn't appear to be echoing out the value of base_url as it appears to be empty for some reason. What makes things weirder is that I have a link in another view file called 'fetch.php' and for some reason it appears to be stripping out the value (XSS filtering is off): <a href="threetune/show"><img src="assets/images/cookie.jpg" /></a> The threetune/show part is not to be seen and I only see an empty href value like this <a href=""><img src="assets/images/cookie.jpg" /></a> Can anyone possibly see anything wrong that I may have done, some kind of Mediatemple server limitation or PHP.ini flag that needs to be set? Thank you and I hope I was descriptive enough.

• Java split xml file

  - by CC

  Hi all, I'm working on a piece of code to split files. I want to split flat file (that's ok, it is working fine) and xml file. The idea is to split based of a number of files to split: I have a file, and I want to split it in x files (x is a parameters). I'm doing the split by taking the size of the file and spliting the size by the number of files to split. Then, mysolution was to use a BufferedReader and to use it like while ((n = reader.read(buffer, 0, buffer.length)) != -1) { { The main problem is that for the xml file I cannot just split it, but I have to split it based on a block delimited by a start xml tag and end xml tag: <start tag> bla bla xml stuff </end tag> So I cannot cut a block at the middle. So if when I'm at the half of a block, is the size of my new file is greater than my max, I will have to read until the end of the tag, and then, to start a next file. The problem is that I have all sort of cases, and is a bit difficult to search the end tag. - the block reads a text until the middle of the end tag - the block reads a text until the end of the end tag, and no more other caracter after - etc and in the same time to have a loop and read the next block. Some times the end of a block concatenated with the start of the next one, I have the end xml tag. I hope you get the idea. My question is, does anyone have some algorithm that does that more accurate and who i treating all special cases ? The idea is to split the file as quickly as possible. Thanks alot.

• Automatically add links to class source files under a specified directory of another project in Visu

  - by Binary255

  I want to share some class source files between two projects in Visual Studio 2008. I can't create a project for the common parts and reference it (see my comment if you are curious to why). I've managed to share some source files, but it could be a lot more neat. I've created a test solution called Commonality. The Solution Explorer of the Commonality solution which contains project One and Two: What I like: All class files under the Common folder of project One are automatically added to project Two by linking. It's mostly the same as if I would have chosen Add / Existing Item... : Add As Link on each new class source file. It's clear that these files have been linked in. The shortcut arrow symbol is marking each file icon. What I do not like: The file and folder tree structure under Common of project One isn't included. It's all flat. The linked source files are shown under the project root of project Two. It would look much less cluttered if they were located under Common like in project One. The file tree structure of the Commonality solution which contains project One and Two: $ tree /F /A Folder PATH listing for volume Cystem Volume serial number is 0713370 1337:F6A4 C:. | Commonality.sln | +---One | | One.cs | | One.csproj | | | +---bin | | \---Debug | | One.vshost.exe | | One.vshost.exe.manifest | | | +---Common | | | Common.cs | | | CommonTwo.cs | | | | | \---SubCommon | | CommonThree.cs | | | +---obj | | \---Debug | | +---Refactor | | \---TempPE | \---Properties | AssemblyInfo.cs | \---Two | Two.cs | Two.csproj | Two.csproj.user | Two.csproj~ | +---bin | \---Debug +---obj | \---Debug | +---Refactor | \---TempPE \---Properties AssemblyInfo.cs And the relevant part of project Two's project file Two.csproj: <ItemGroup> <Compile Include="..\One\Common\**\*.cs"> </Compile> <Compile Include="Two.cs" /> <Compile Include="Properties\AssemblyInfo.cs" /> </ItemGroup> How do I address what I do not like, while keeping what I like?

• Yet another Python Windows CMD mklink problem ... can't get it to work!

  - by Felix Dombek

  OK I have just posted another question which outlined my program but the specific problem was different. Now, my program just stops working without any message whatsoever. I'd be grateful if someone could help me here. I want to create symlinks for each file in a directory structure, all in one large flat folder, and have the following code by now: # loop over directory structure: # for all items in current directory, # if item is directory, recurse into it; # else it's a file, then create a symlink for it def makelinks(folder, targetfolder, cmdprocess = None): if not cmdprocess: cmdprocess = subprocess.Popen("cmd", stdin = subprocess.PIPE, stdout = subprocess.PIPE, stderr = subprocess.PIPE) print(folder) for name in os.listdir(folder): fullname = os.path.join(folder, name) if os.path.isdir(fullname): makelinks(fullname, targetfolder, cmdprocess) else: makelink(fullname, targetfolder, cmdprocess) #for a given file, create one symlink in the target folder def makelink(fullname, targetfolder, cmdprocess): linkname = os.path.join(targetfolder, re.sub(r"[\/\\\:\*\?\"\<\>\|]", "-", fullname)) if not os.path.exists(linkname): try: os.remove(linkname) print("Invalid symlink removed:", linkname) except: pass if not os.path.exists(linkname): cmdprocess.stdin.write("mklink " + linkname + " " + fullname + "\r\n") So this is a top-down recursion where first the folder name is printed, then the subdirectories are processed. If I run this now over some folder, the whole thing just stops after 10 or so symbolic links. Here is the output: D:\Musik\neu D:\Musik\neu\# Electronic D:\Musik\neu\# Electronic\# tag & reencode D:\Musik\neu\# Electronic\# tag & reencode\ChillOutMix D:\Musik\neu\# Electronic\# tag & reencode\Unknown D&B D:\Musik\neu\# Electronic\# tag & reencode\Unknown D&B 2 The program still seems to run but no new output is generated. It created 9 symlinks for some files in the # tag & reencode and the first three files in the ChillOutMix folder. The cmd.exe Window is still open and empty, and shows in its title bar that it is currently processing the mklink command for the third file in ChillOutMix. I tried to insert a time.sleep(2) after each cmdprocess.stdin.write in case Python is just too fast for the cmd process, but it doesn't help. Does anyone know what the problem might be?

• Having trouble animating Line in D3.js using and array of objects as data

  - by user1731245

  I can't seem to get an animated transition between line graphs when I pass in a new set of data. I am using an array of objects as data like this: [{ clicks: 40 installs: 10 time: "1349474400000" },{ clicks: 61 installs: 3 time: "1349478000000" }]; I am using this code to setup my ranges / axis's var xRange = d3.time.scale().range([0, w]), yRange = d3.scale.linear().range([h , 0]), xAxis = d3.svg.axis().scale(xRange).tickSize(-h).ticks(6).tickSubdivide(false), yAxis = d3.svg.axis().scale(yRange).ticks(5).tickSize(-w).orient("left"); var clicksLine = d3.svg.line() .interpolate("cardinal") .x(function(d){return xRange(d.time)}) .y(function(d){return yRange(d.clicks)}); var clickPath; function drawGraphs(data) { clickPath = svg.append("g") .append("path") .data([data]) .attr("class", "clicks") .attr("d", clicksLine); } function updateGraphs(data) { svg.select('path.clicks') .data([data]) .attr("d", clicksLine) .transition() .duration(500) .ease("linear") } I have tried just about everything to be able to pass in new data and see an animation between graph's. Not sure what I am missing? does it have something to do with using an array of objects instead of just a flat array of numbers as data?

• Updates to fullcalendar events (through updateEvent) not maintaining across ajax month changes

  - by user549615

  Hey there. I have the calendar configured to allow me to edit and add (drag/drop) calendar events. I use .fullCalendar('updateEvent', theEvent) to edit an event, and it immediately updates on the page. Excellent. If I move to another month and then move back (get via ajax), that change is undone. By contrast, if I add a new event by drag/drop using: .fullCalendar('renderEvent', newEventObject, true); it appears on the calendar, and if I move to another month, and move back, it maintains. If I edit this newly added event object, and move to another month and back, the updates are retained! So the "stickiness" of edits seem to work on newly added events, but not events that were pulled via ajax (since it just pulls a fresh version via ajax when the month changes). My calendar config is: $('#calendar').fullCalendar({ theme: true, header: { left: "prev,next today", center: 'title', right: "today prev,next" }, selectable: true, selectHelper: true, select: calendarSelect, droppable: true, drop: calendarDrop, events:getCalendarData, eventClick:calendarEventClicked }); I tried setting editable: true, as well, but no dice. I noticed that if I view "event.source" on one of the ajax pulled events, it shows me a function, and if i read the source attribute on one of the "added" events, it reads [object]. So I tried setting the event.source of the event being added, to that same event object: curCalendarEvent.source = curCalendarEvent But no dice. It sets, but when I move back month forward again, it returns to the function as a source. I tried adding lazyFetching: false to my calendar config, but that didn't help. I even tried a .fullCalendar('renderEvent', curCalendarEvent, true); on the existing "edited" event to see if I could get "stick" to work, and it didn't help. The only thing I can think of doing is deleting the event flat out and recreating it. Any help would be appreciated. -Brian

• Translate XSD element names to English

  - by Coov

  I have an XML Schema Definition file .XSD who's elements are in Spanish. I have an XML data file that is also in Spanish that matches the schema definition. I created a dataset from the xsd using xsd.exe and I'm loading the XML into the dataset. I want to translate the element names to English. I can think of two options off the top of my head. Either scrape the XSD & XML files and translate the elements prior to generating the dataset with esd.exe, or iterate the dataset after I have loaded it with the xml, and translate my objects. I do have a written document that provides the English names for every element name in Spanish. The problem is there are hundreds of elements and I was trying to avoid coding that manually. Getting precise translations is not that important, it just needs to be readable by an English speaking person. Here is an example of what an element may look like "Apellidos": <xs:element name="Apellidos" type="xs:string"/> that I will translate to "SirName": <xs:element name="SirName" type="xs:string"/> I'm looking for ideas and or opinions on a quick way to do this. It's a one time deal so I'm not working about it scaling or being functional for things other than this single xml file. I'll be taking this dataset and writing out a flat file for English speaking users to read.

• Which linear programming package should I use for high numbers of constraints and "warm starts"

  - by davidsd

  I have a "continuous" linear programming problem that involves maximizing a linear function over a curved convex space. In typical LP problems, the convex space is a polytope, but in this case the convex space is piecewise curved -- that is, it has faces, edges, and vertices, but the edges aren't straight and the faces aren't flat. Instead of being specified by a finite number of linear inequalities, I have a continuously infinite number. I'm currently dealing with this by approximating the surface by a polytope, which means discretizing the continuously infinite constraints into a very large finite number of constraints. I'm also in the situation where I'd like to know how the answer changes under small perturbations to the underlying problem. Thus, I'd like to be able to supply an initial condition to the solver based on a nearby solution. I believe this capability is called a "warm start." Can someone help me distinguish between the various LP packages out there? I'm not so concerned with user-friendliness as speed (for large numbers of constraints), high-precision arithmetic, and warm starts. Thanks!

• Is functional GUI programming possible?

  - by eman

  I've recently caught the FP bug (trying to learn Haskell), and I've been really impressed with what I've seen so far (first-class functions, lazy evaluation, and all the other goodies). I'm no expert yet, but I've already begun to find it easier to reason "functionally" than imperatively for basic algorithms (and I'm having trouble going back where I have to). The one area where current FP seems to fall flat, however, is GUI programming. The Haskell approach seems to be to just wrap imperative GUI toolkits (such as GTK+ or wxWidgets) and to use "do" blocks to simulate an imperative style. I haven't used F#, but my understanding is that it does something similar using OOP with .NET classes. Obviously, there's a good reason for this--current GUI programming is all about IO and side effects, so purely functional programming isn't possible with most current frameworks. My question is, is it possible to have a functional approach to GUI programming? I'm having trouble imagining what this would look like in practice. Does anyone know of any frameworks, experimental or otherwise, that try this sort of thing (or even any frameworks that are designed from the ground up for a functional language)? Or is the solution to just use a hybrid approach, with OOP for the GUI parts and FP for the logic? (I'm just asking out of curiosity--I'd love to think that FP is "the future," but GUI programming seems like a pretty large hole to fill.)

• How can I use Django with MySQL in MAMP stack?

  - by Robert A Henru

  Hi all, I have difficulty especially in installing MySQLdb module (MySQL-python-1.2.3c1), to connect to the MySQL in MAMP stack. I've done a number of things such as copying the mysql include directory and library (including plugin) from a fresh installation of mysql (version 5.1.47) to the one inside MAMP (version 5.1.37). Now, the MySQLdb module build and install doesnt give me error. The error happens when I'm calling 'import MySQLdb' from python shell (version 2.6).

• How to hide zero values in bar3 plot in MATLAB

  - by Doresoom

  I've got a 2-D histogram (the plot is 3D - several histograms graphed side by side) that I've generated with the bar3 plot command. However, all the zero values show up as flat squares in the x-y plane. Is there a way I can prevent MATLAB from displaying the values? I already tried replacing all zeros with NaNs, but it didn't change anything about the plot. Here's the code I've been experimenting with: x1=normrnd(50,15,100,1); %generate random data to test code x2=normrnd(40,13,100,1); x3=normrnd(65,12,100,1); low=min([x1;x2;x3]); high=max([x1;x2;x3]); y=linspace(low,high,(high-low)/4); %establish consistent bins for histogram z1=hist(x1,y); z2=hist(x2,y); z3=hist(x3,y); z=[z1;z2;z3]'; bar3(z) As you can see, there are quite a few zero values on the plot. Closing the figure and re-plotting after replacing zeros with NaNs seems to change nothing: close z(z==0)=NaN; bar3(z)

• Lighting does not work with gluSphere

  - by badcodenotreat

  This is a simple issue that I'm somewhat ashamed to ask for help on. I'm making a simple call to gluSphere to render a sphere, however, it does not light properly even though I'm pretty sure I added the normals and lighting correctly. If, however, I add a texture, the model lights normally, except it seems to be always SMOOTH, and I cannot change it to flat. This is the lighting code in my init() function: gl.glLightfv( GL.GL_LIGHT0, GL.GL_AMBIENT , AMBIENT_LIGHT, 0 ); gl.glLightfv( GL.GL_LIGHT0, GL.GL_DIFFUSE , DIFFUSE_LIGHT, 0 ); gl.glLightfv( GL.GL_LIGHT0, GL.GL_POSITION, light_pos , 0 ); gl.glEnable ( GL.GL_LIGHT0 ); gl.glEnable ( GL.GL_LIGHTING ); this is my sphere code in my display() function: gl.glColor3d(1.0, 1.0, 1.0); glu.gluQuadricDrawStyle (quad, GLU.GLU_FILL); glu.gluQuadricNormals (quad, GLU.GLU_FLAT); glu.gluQuadricOrientation(quad, GLU.GLU_OUTSIDE); glu.gluSphere(quad, 1.0, lat, lon); Please advise.

• FindControl in DataList Edit Mode

  - by Doug

  As a new .net/C# web begginner, I always get tripped up when I try to use FindControl. Blam -flat on my face. Here is my current FindControl problem: I have an .aspx page and Form, then ajax updatePanel, inside it there is my DataList (DataList1) that has an EditItemTemplate: that has the following: <EditItemTemplate> <asp:Label ID="thumbnailUploadLabel" runat="server" text="Upload a new thumbnail image:"/><br /> <asp:FileUpload ID="thumbnailImageUpload" runat="server" /> <asp:Button ID="thunbnailImageUploadButton" runat="server" Text="Upload Now" OnClick="thumbnailUpload"/><br /> </EditItemTemplate> In my C# code behind I have the OnClick code for the fileUpload object: protected void thumbnailUpload(object s, EventArgs e) { if (thumbnailImageUpload.HasFile) { //get name of the file & upload string imageName = thumbnailImageUpload.FileName; thumbnailImageUpload.SaveAs(MapPath("../../images/merch_sm/" + imageName)); //let'em know that it worked (or didn't) thumbnailUploadLabel.Text = "Image " + imageName + "has been uploaded."; } else { thumbnailUploadLabel.Text = "Please choose a thumbnail image to upload."; } So of course I'm getting "Object reference not set to an instance of an object" for the FileUpload and the Label. What is the correct syntax to find these controls, before dealing with them in the OnClick event? The only way Ive used FindControl is something like: label thumbnailUploadLabel = DataList1.FindControl("thumbnailUploadLabel") as Label; But of course this is throwing the "Object reference not set to an instance of an object" error. Any help is very much appreciated. (I've also seen the 'recursive' code out there that is supposed to make using FindControl easier. Ha! I'm so green at C# that I don't even know how to incorporate those into my project.) Thanks to all for taking a look at this.

• How can I make this method more Scalalicious

  - by Neil Chambers

  I have a function that calculates the left and right node values for some collection of treeNodes given a simple node.id, node.parentId association. It's very simple and works well enough...but, well, I am wondering if there is a more idiomatic approach. Specifically is there a way to track the left/right values without using some externally tracked value but still keep the tasty recursion. /* * A tree node */ case class TreeNode(val id:String, val parentId: String){ var left: Int = 0 var right: Int = 0 } /* * a method to compute the left/right node values */ def walktree(node: TreeNode) = { /* * increment state for the inner function */ var c = 0 /* * A method to set the increment state */ def increment = { c+=1; c } // poo /* * the tasty inner method * treeNodes is a List[TreeNode] */ def walk(node: TreeNode): Unit = { node.left = increment /* * recurse on all direct descendants */ treeNodes filter( _.parentId == node.id) foreach (walk(_)) node.right = increment } walk(node) } walktree(someRootNode) Edit - The list of nodes is taken from a database. Pulling the nodes into a proper tree would take too much time. I am pulling a flat list into memory and all I have is an association via node id's as pertains to parents and children. Adding left/right node values allows me to get a snapshop of all children (and childrens children) with a single SQL query. The calculation needs to run very quickly in order to maintain data integrity should parent-child associations change (which they do very frequently). In addition to using the awesome Scala collections I've also boosted speed by using parallel processing for some pre/post filtering on the tree nodes. I wanted to find a more idiomatic way of tracking the left/right node values. After looking at the answers listed I have settled on this synthesised version: def walktree(node: TreeNode) = { def walk(node: TreeNode, counter: Int): Int = { node.left = counter node.right = treeNodes .filter( _.parentId == node.id) .foldLeft(counter+1) { (counter, curnode) => walk(curnode, counter) + 1 } node.right } walk(node,1) }

• Payment Processors - What do I need to know if I want to accept credit cards on my website?

  - by Michael Pryor

  This question talks about different payment processors and what they cost, but I'm looking for the answer to what do I need to do if I want to accept credit card payments? Assume I need to store credit card numbers for customers, so that the obvious solution of relying on the credit card processor to do the heavy lifting is not available. PCI Data Security, which is apparently the standard for storing credit card info, has a bunch of general requirements, but how does one implement them? And what about the vendors, like Visa, who have their own best practices? Do I need to have keyfob access to the machine? What about physically protecting it from hackers in the building? Or even what if someone got their hands on the backup files with the sql server data files on it? What about backups? Are there other physical copies of that data around? Tip: If you get a merchant account, you should negotiate that they charge you "interchange-plus" instead of tiered pricing. With tiered pricing, they will charge you different rates based on what type of Visa/MC is used -- ie. they charge you more for cards with big rewards attached to them. Interchange plus billing means you only pay the processor what Visa/MC charges them, plus a flat fee. (Amex and Discover charge their own rates directly to merchants, so this doesn't apply to those cards. You'll find Amex rates to be in the 3% range and Discover could be as low as 1%. Visa/MC is in the 2% range). This service is supposed to do the negotiation for you (I haven't used it, this is not an ad, and I'm not affiliated with the website, but this service is greatly needed.) This blog post gives a complete rundown of handling credit cards (specifically for the UK).

• Automatically add links to class source files under a specified directory of an another project in V

  - by Binary255

  I want to share some class source files between two projects in Visual Studio 2008. I can't create a project for the common parts and reference it (see my comment if you are curious to why). I've managed to share some source files, but it could be a lot more neat. I've created a test solution called Commonality. The Solution Explorer of the Commonality solution which contains project One and Two: What I like: All class files under the Common folder of project One are automatically added to project Two by linking. It's mostly the same as if I would have chosen Add / Existing Item... : Add As Link on each new class source file. It's clear that these files have been linked in. The shortcut arrow symbol is marking each file icon. What I do not like: The file and folder tree structure under Common of project One isn't included. It's all flat. The linked source files are shown under the project root of project Two. It would look much less cluttered if they were located under Common like in project One. The file tree structure of the Commonality solution which contains project One and Two: $ tree /F /A Folder PATH listing for volume Cystem Volume serial number is 0713370 1337:F6A4 C:. | Commonality.sln | +---One | | One.cs | | One.csproj | | | +---bin | | \---Debug | | One.vshost.exe | | One.vshost.exe.manifest | | | +---Common | | | Common.cs | | | CommonTwo.cs | | | | | \---SubCommon | | CommonThree.cs | | | +---obj | | \---Debug | | +---Refactor | | \---TempPE | \---Properties | AssemblyInfo.cs | \---Two | Two.cs | Two.csproj | Two.csproj.user | Two.csproj~ | +---bin | \---Debug +---obj | \---Debug | +---Refactor | \---TempPE \---Properties AssemblyInfo.cs And the relevant part of project Two's project file Two.csproj: <ItemGroup> <Compile Include="..\One\Common\**\*.cs"> </Compile> <Compile Include="Two.cs" /> <Compile Include="Properties\AssemblyInfo.cs" /> </ItemGroup> How do I address what I do not like, while keeping what I like?

• In PHP... best way to turn string representation of a folder structure into nested array

  - by Greg Frommer

  Hi everyone, I looked through the related questions for a similar question but I wasn't seeing quite what I need, pardon if this has already been answered already. In my database I have a list of records that I want represented to the user as files inside of a folder structure. So for each record I have a VARCHAR column called "FolderStructure" that I want to identify that records place in to the folder structure. The series of those flat FolderStructure string columns will create my tree structure with the folders being seperated by backslashes (naturally). I didn't want to add another table just to represent a folder structure... The 'file' name is stored in a separate column so that if the FolderStructure column is empty, the file is assumed to be at the root folder. What is the best way to turn a collection of these records into a series of HTML UL/LI tags... where each LI represents a file and each folder structure being an UL embedded inside it's parent?? So for example: file - folderStructure foo - bar - firstDir blue - firstDir/subdir would produce the following HTML: <ul> <li>foo</li> <ul> <li> bar </li> <ul> <li> blue </li> </ul> </ul> </ul> Thanks

• One-sided rounded buttons in Silverlight

  - by xarzu

  I want to make a collection of buttons in silverlight. They are in a collection that goes from left to right and the buttons are lined up so that they are touching on the left and right sides. Here is the rub: The collection has rounded corners but the buttons in between the end buttons in the collection do not have rounded ends. So basically, for the buttons on the far left and right side of the collection, they have to be somewhat special because they have to have one flat vertical side and one rounded side. Is this possible to do in silverlight without resorting to making a special bitmap for the end buttons? One idea I have is somehow declare a canvas with a bitmap background and then have overlapping ellipse and rectangle <Canvas Height="100" HorizontalAlignment="Left" Margin="189,381,0,0" VerticalAlignment="Top" Width="200" Background="Black"> <Rectangle Fill="#FFF4F4F5" HorizontalAlignment="Left" Stroke="Black" Width="58" Height="61" Canvas.Left="7" Canvas.Top="16" /> <Ellipse Fill="#FFF4F4F5" HorizontalAlignment="Left" Stroke="White" Width="65" StrokeThickness="0" Height="59" Canvas.Left="31" Canvas.Top="17" /> </Canvas>

• silverlight treeview not loading subitems

  - by Jakob

  I'm interested in finding out why this isn't working: I have a treeview with some hierarchicaldatatemplates looking like this: <UserControl.Resources> <sdk:HierarchicalDataTemplate x:Key="nodeEntry"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=Title}" /> </StackPanel> </sdk:HierarchicalDataTemplate> <sdk:HierarchicalDataTemplate x:Key="rootEntry" ItemsSource="{Binding Path=Nodes}" ItemTemplate="{StaticResource nodeEntry}"> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=Name}" /> </StackPanel> </sdk:HierarchicalDataTemplate> </UserControl.Resources> <sdk:TreeView Height="250" HorizontalAlignment="Left" ItemTemplate="{StaticResource rootEntry}" ItemsSource="{Binding ElementName=subjectDomainDataSource, Path=Data}" Name="rootTreeView" VerticalAlignment="Top" Width="180"/> The data is passed to the treeview from a domainservice using this method: public IEnumerable<Subject> GetSubjectList(Guid userid) { DataLoadOptions loadopts = new DataLoadOptions(); loadopts.LoadWith<Root>(s => s.Nodes); this.DataContext.LoadOptions = loadopts; return this.DataContext.Roots; } why then are only the root nodes shown in the treeview as if it only loaded a flat list, and not a hierarchy where the root Loads the NodesCollection?

• How do I create a selection list in ASP.NET MVC?

  - by Gary McGill

  I have a database table that records what publications a user is allowed to access. The table is very simple - it simply stores user ID/publication ID pairs: CREATE TABLE UserPublication (UserId INTEGER, PublicationID INTEGER) The presence of a record for a given user & publication means that the user has access; absence of a record implies no access. I want to present my admin users with a simple screen that allows them to configure which publications a user can access. I would like to show one checkbox for each of the possible publications, and check the ones that the user can currently access. The admin user can then check or un-check any number of publications and submit the form. There are various publication types, and I want to group the similarly-typed publications together - so I do need control over how the publications are presented (I don't want to just have a flat list). My view model obviously needs to have a list of all the publications (since I need to display them all regardless of the current selection), and I also need a list of the publications that the user currently has access to. (I'm not sure whether I'd be better off with a single list where each item includes the publication ID and a yes/no field?). But that's as far as I've got. I've really no idea how to go about binding this to some checkboxes. Where do I start?
