• SQL Reporting Services - Subreports Broken into multiple columns

  - by devin

  Hi, I inherited an SQL Reporting Services .rdl project from somebody and need help fixing some functionality. In each row of the report, there is a subreport. In order to save space the subreport is divided into 3. Such that in each row of the report, it splits the data of the subreport into 3 smaller tables. Right now, it fills these 3 subreports horizontally. (ie. if the result has 9 values, the first subtable will have 1, 4 & 7, the second subtable will have 2, 5 & 8, etc) Is there a way to have it fill the subtables vertically? (ie. the first subtable would have 1,2 & 3) Thanks!

• Error reading in date using Zoo in R

  - by SASnewby

  I am trying to use the Zoo package to read in daily observations which do not occur on each day. The date format looks like this, and it is in the first column of dataset: 25-May-07 The command I use is: z <- read.zoo("multiplier7.csv", sep = ";", header = TRUE, format="%d-%b-%y") I get this error: Error in strptime(x, format, tz = "GMT") : input string is too long First question is: 1. Is Zoo the right package to use if I want to use lm regression with a spline time dummy? The bs command does not work because I need to convert it into a time series. 2. Why is this error occurring and how to fix?

• UITextField valueDidChange-Event

  - by Infinite

  Is there a way to catch a "valueDidChange"-Event for a Textfield? oO I've got a modalView with an UITextField. When the UITextField is empty, the "Done"-Button in the NavigationBar should be disabled and when there is Text entered, it should become enabled. Right now the only way to accomplish this by using the "textFieldShouldReturn"-Method. This works but is simply horrible for usability. Isn't there a way to check the requirements every time a letter is being entered or removed?

• Urlrewriting.net pages are not causing postbacks

  - by Nick

  I'm using webforms with UrlRewriting.Net to rewrite pages, e.g. http://www.example.com/stuff.aspx?c=30 becomes http://www.example.com/stuff/30-this-stuff.aspx. It works in so far as the correct content is loading; however, none of the postbacks are working (mostly buttons on the page). If I set up a breakpoint on Page_Load, I see that IsPostBack is always false. Any ideas on how to fix this? Right now I'm just on Visual Studio 2008. EDIT: I have since switched to UrlRewriter.Net, which worked after a few tweaks (see Scott Gu's article). Besides here, I have posted my original problem to the developer's forum: if I ever get an answer, I'll post it here (unless else posts it here first).

• jqGrid "Loading..." overlay showing "undefined" though grid is working

  - by gurun8

  I have a jqGrid that's working 100% except that it keeps displaying "undefined" in the "Loading..." overlay. I can't really figure it out. It seems like I should only get the "undefined" message if something isn't set right and the grid would cease to work. But that's not the case. scratches head I'm not really sure a code sample would help here, but if anyone would like to see a certain part of my code let me know and I'll included. Has anyone else come across this issue before? I'm probably missing something so simple and small that I can't see it. So my apologies in advance if this is a no-brainer Thanks for your help.

• Weird "406 not acceptable" error

  - by Horace Loeb

  When I try to hit this action via Javascript, I get a 406 Not Acceptable error: def show @annotation = Annotation.find_by_id(params[:id]) respond_to do |format| format.html { if @annotation.blank? redirect_to root_path else redirect_to inline_annotation_path(@annotation) end } format.js { if params[:format] == "raw" render :text => @annotation.body.to_s else render :text => @annotation.body.to_html end } end end This is from jQuery, but I'm doing the right beforeSend stuff: $.ajaxSetup({ beforeSend: function(xhr) { xhr.setRequestHeader("Accept", "text/javascript"); }, cache: false }); Here are my request headers: Host localhost:3000 User-Agent Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 Accept text/javascript Accept-Language en-us,en;q=0.5 Accept-Encoding gzip,deflate Accept-Charset ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive 300 Connection keep-alive X-Requested-With XMLHttpRequest Content-Type application/x-www-form-urlencoded

• Using CHDataStructures.framework on iPhone

  - by nununo

  Hi, I'm new to iPhone programming and I'm trying to use CHDataStructures in my project. But I'm running into some issues: When I directly try to build it right after download I get the error "Foundation/Foundation.h" no such file or directory. The Active SDK is "Use Base SDK" and the active architecture is x86_64. I believe I should set the Active SDK to the iPhone SDK but it isn't listed there; At some point (I don't remember how) I managed to tweak it and I got the iPhone SDK (simulator) in the active SDK but when I tried to build it I got the following error: "target specifies product type 'com.apple.product-type.framework', but there's no such product type for the 'iphonesimulator' platform"; And now I'm stuck. What am I doing wrong? Thanks in advance, Nuno

• Problems trying to use Visual Studio 2010 and AJAX extensions

  - by Adrian

  Why can I not add ScriptManager control or UpdatePanel to a page in Visual Studio 2010? The drag( or double click) just fails - it seems like there is an incompatibility somewhere? UPDATE: This is 'default' install of 2010 Ultimate on Windows7, create a web application, cannot drag ScriptManager or UpdatePanel to the designer. Typing the declarations works. The cursor changes to the [+] icon when you drag it to the right place but nothing appears to happens on 'drop', briefly the documents name has * appended, this quickly changes back to normal, either is saves or does an undo. I'm assuming something is going wrong so it undos...but what is going wrong?

• Is there a way to mark up code to tell ReSharper not to format it?

  - by adrianbanks

  I quite often use the ReSharper "Clean Up Code" command to format my code to our coding style before checking it into source control. This works well in general, but some bits of code are better formatted manually (eg. because of the indenting rules in ReSharper, things like chained linq methods or multi-line ternary operators have a strange indent that pushes them way to the right). Is there any way to mark up parts of a file to tell ReSharper not to format that area? I'm hoping for some kind of markup similar to how ReSharper suppresses other warnings/features. If not, is there some way of changing a combination of settings to get ReSharper to format the indenting correctly? EDIT: I have found this post from the ReSharper forums that says that generated code sections (as defined in the ReSharper options page) are ignored in code cleanup. Having tried it though, it doesn't seem to get ignored.

• IE dropdown z-index bug

  - by Justine

  I'm having a problem with a dropdown menu under IE (6 and 7). http://www.amaconsulting.pl/promocje.html As you can see, the dropdown hides behind the main content area in IE. It's a known bug and general advice is to set a z-index for header and content areas, so IE knows their "place", explained in the article here: http://bit.ly/coSPcI I've set the z-index of .header div to 20 and .featured, .content, .primary, .main to 1, trying to find the right div to fix the problem. While the dropdown stopped hiding behind the .featured div, it still hides behind the main content divs (either .primary or .main, .secondary is fine). The z-indexes for these divs are set in a separate stylesheet, ie.css, in case someone'll be looking for them. If someone could provide some advice, I'd be very grateful.

• complicated graphviz tree structure

  - by thomas

  Hello. I am trying to create a tree structure with graphviz. I am open to either writing the graphviz code by hand or using the ruby-graphviz gem for ruby. Given the below picture can anyone provide any insight on the necessary code? Ignore that the lines are not straight...they should be when graphviz builds the graph. I am open to having dots/points when lines intersect as well. I have played with ruby-graphviz and the family tree class...this is getting me part of the way there but I really need all lines to be straight and intersect at right angles and the out-of-the-box code doesn't seem to do that.

• Python's Popen cleanup

  - by pythonic metaphor

  I wanted to use a python equivalent to piping some shell commands in perl. Something like the python version of open(PIPE, "command |"). I go to the subprocess module and try this: p = subprocess.Popen("zgrep thingiwant largefile", shell=True, stdout=subprocess.PIPE) This works for reading the output the same way I would in perl, but it doesn't clean itself up. When I exit the interpreter, I get grep: writing output: Broken pipe spewed all over stderr a few million times. I guess I had naively hoped all this would be taken care of for me, but that's not true. Calling terminate or kill on p doesn't seem to help. Look at the process table, I see that this kills the /bin/sh process, but leaves the child gzip in place to complain about the broken pipe. What's the right way to do this?

• UIButton of type UIButtonTypeCustom will not display Title (iPhone)

  - by RickiG

  Hi I must have overlooked something completely obvious?? but my button displays its image and size correctly, but I simply can't get the Title to show up. I did a really simple test, the Title does not even show up when I do this: CGRect frameBtn = CGRectMake(160.0f, 150.0f, 144.0f, 42.0f); UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; [button setImage:[UIImage imageNamed:@"left_halfscreen_button.png"] forState:UIControlStateNormal]; [button setTitle:@"Hello" forState:UIControlStateNormal]; [button setFrame:frameBtn]; NSLog(@"Title:%@", [button currentTitle]); //prints "Title:Hello [self addSubview:button]; I have a factory class that generates custom buttons for me and I thought I messed some detail up there, so I moved the above code directly into my UIView, the title is still blank. Is this a bug or am I simply missing something right in front of my eyes. Thank you for the extra set of eyes:)

• How to calculate line count for project

  - by sixtyfootersdude

  I am taking a software engineering class right now. Our assignment is to evaluate Mozilla's Thunderbird. Our assignment is to evaluate the size of Thunderbird. One metric that we need to use is the number of lines of code in the project. (Lines of code meaning not including comments or new lines). Is there a standard way to find the number of lines or am I better off just cracking out a script to do this? I think that I could do something like this: # remove all comments find -name *.java | \ sed "/\/*/,\*\// s/.*//g | \ # remove multiline comments sed s/\/\///g # remove single line comments # count not empty lines find -name *.java | grep -c "<character>" But I would need to do that for each file type. It seems like there should be some utility that does that already. (something mac/unix compatible would be preferable).

• SSAS: distribution of measures over percentage

  - by Alex

  Hi there, I am running a SSAS cube that stores facts of HTTP requests. The is a column "Time Taken" that stores the milliseconds a particular HTTP request took. Like... RequestID Time Taken -------------------------- 1 0 2 10 3 20 4 20 5 2000 I want to provide a report through Excel that shows the distribution of those timings by percentage of requests. A statement like "90% of all requests took less than 20millisecond". Analysis: 100% <2000 80% <20 60% <20 40% <10 20% <=0 I am pretty much lost what would be the right approach to design aggregations, calculations etc. to offer this analysis through Excel. Any ideas? Thanks, Alex

• WPF MVVM: how to bind GridViewColumn to ViewModel-Collection?

  - by Sam

  In my View I got a ListView bound to a CollectionView in my ViewModel, for example like this: <ListView ItemsSource="{Binding MyCollection}" IsSynchronizedWithCurrentItem="true"> <ListView.View> <GridView> <GridViewColumn Header="Title" DisplayMemberBinding="{Binding Path=Title}"/> <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Path=Name}"/> <GridViewColumn Header="Phone" DisplayMemberBinding="{Binding Path=Phone}"/> <GridViewColumn Header="E-mail" DisplayMemberBinding="{Binding Path=EMail}"/> </GridView> </ListView.View> </ListView> Right now these GridViewColumns are fixed, but I'd like to be able to change them from the ViewModel. I'd guess I'll have to bind the GridViewColumn-collection to something in the ViewModel, but what, and how? The ViewModel does know nothing of WPF, so I got no clue how to achieve this in MVVM. any help here?

• calling contextmenustrip programmatically c#

  I programmatically create a Picture Box in c# windows program. I assign it with a value for the Tag property. I would like to print out that tag number programmatically, just for test purposes. so I try this: private void Form1_Load(object sender, EventArgs e) { pic.ContextMenuStrip = contextMenuStrip1; pic.ContextMenuStrip.Click += new EventHandler(this.MyPicHandler); } void MyPicHandler(object sender, EventArgs e) { PictureBox pic = sender as PictureBox; MessageBox.Show(pic.Tag.ToString()); } But when I right-click on the picture, and click on the menu item, it gives me an exception.

• DataGridView Selected Row Move UP and DOWN

  - by Silly Rabbit

  How can I allow selected rows in a DataGridView (DGV) to be moved up or down. I have done this before with a ListView. Unfortunetly, for me, replacing the DGV is not an option (curses). By the way, the DGV datasource is a Generic Collection. The DGV has two buttons on the side, yes, UP & Down. Can anyone help point me in the right direction. I do have the code that I used for the ListView if it'll help (it did not help me).

• How to do Selection Alignment using the RichTextBox in Silverlight 4?

  - by RoguePlanetoid

  I cannot seem to figure out how to do a Selection Alignment in the new RichTextBox, I have an idea that I need to convert the selection into the Paragraph type which supports alignment, but cannot seem to figure this out. None of the Silverlight examples have this, but I'm sure it is possible. I have this code, that does not work - as I think I need the selection to be a Paragraph as it always returns and Exception "Value does not fall within the expected range". Editor.Selection.SetPropertyValue(Paragraph.TextAlignmentProperty, TextAlignment.Left) I make sure I check for a Valid Selection first, code like the following works for "Bold": If Editor.Selection.Text.Length > 0 Then ' Text Selected If TypeOf Editor.Selection.GetPropertyValue(Run.FontWeightProperty) Is FontWeight _ AndAlso DirectCast(Editor.Selection.GetPropertyValue(Run.FontWeightProperty), FontWeight) = FontWeights.Normal Then Editor.Selection.SetPropertyValue(Run.FontWeightProperty, FontWeights.Bold) Else Editor.Selection.SetPropertyValue(Run.FontWeightProperty, FontWeights.Normal) End If End If Editor.Focus() Example in XAML: <Paragraph TextAlignment="Right">Example</Paragraph> The above works in the contents of a RichTextBox however I need to do this programatically based on a selection - like in WordPad.

• Proper usage of JTidy to purify HTML

  - by Raj

  Hello, I am trying to use JTidy (jtidy-r938.jar) to sanitize an input HTML string, but I seem to have problems getting the default settings right. Often strings such as "hello world" end up as "helloworld" after tidying. I wanted to show what I'm doing here, and any pointers would be really appreciated: Assume that rawHtml is the String containing the input (real world) HTML. This is what I'm doing: InputStream is = new ByteArrayInputStream(rawHtml.getBytes("UTF-8")); Tidy tidy = new Tidy(); tidy.setQuiet(true); tidy.setShowWarnings(false); tidy.setXHTML(true); ByteArrayOutputStream baos = new ByteArrayOutputStream(); tidy.parseDOM(is, baos); String pure = baos.toString(); First off, does anything look fundamentally wrong with the above code? I seem to be getting weird results with this. Thanks in advance!

• jquery cycle "allowPagerClickBubble: true" not quite working

  - by Shelagh

  Hi all, I want my page anchors to work as menu links so I used this code: $(function() { $('#slideshow').cycle({ slideExpr: 'img', fx: 'fade', speed: 2000, timeout: 4000, pager: '#nav', pagerEvent: 'mouseover', pauseOnPagerHover: true, pagerAnchorBuilder: function(idx, slide) { // return sel string for existing anchor return '#nav li:eq(' + (idx) + ') a'; }, allowPagerClickBubble: true }); }); If you click the right mouse button, you can choose to open the links and they do open just fine but a normal left button click does nothing. The thing is, they WERE working so I went to work on supposedly unrelated parts of the website and at some point the left mouse button click stopped working. Any ideas what I might have done? Left button clicking still works for everything else on the site so its not some global setting. The cycle is here if my explanation is not clear: http://www.mcguirenaturals.ca/index.php Thanks for any help

• Visual Studio 2008 maintenance mode - I can't remember my installation source drive letter!!!

  - by Dave

  I've searched high and low for this and can't find the answer anywhere. I installed VS2008, but my drive letters are all mapped differently now, and of course I need to add a component to my current installation (VC++). But since I don't know which drive letter it was installed from, and since I don't want to try to figure it out the brute force way, I was hoping that someone here knew how to figure that out. I poked through HKCU and HKLM in the registry, hoping to find the info there, but couldn't. Does anyone know how to get this to work? Right now, I get the error "A selected drive is no longer valid. Please review your installation path settings before continuing with setup".

• issues horizontal scrolling using jQuery.ScrollTo / jQuery.SerialScroll

  - by kapil.israni

  Hi, I am trying to develop auto horizontal scrolling for our website using - jQuery.ScrollTo / jQuery.SerialScroll. I am not sure if this is the best jquery library to do that, but if there's something better, please let me know. Here's the behavior that I want, check out foursquare's "Recent Activity" list. The data that will refresh will come from a ajax request that I make every few seconds using window.setInterval. I am not really a CSS/java script guy so I havent been able to figure out jQuery.SerialScroll. Here's the website - look at the "Live job Feeds" list. Currently the list does refresh the data coming from the ajax call, but I dont see the effect, the animation, in fact I dont even think serialScroll is being used. Right now I am doing a - $('#feed-ticker').prepend(content) to pre-append the newly arrived data. You can do a view source to look at the current code. Any help would be really appreciated. Thanks.

• Html Agility Pack get all elements by class

  - by Adam

  I am taking a stab at html agility pack and having trouble finding the right way to go about this. For example: var findclasses = _doc.DocumentNode.Descendants("div").Where(d => d.Attributes.Contains("class")); However, obviously you can add classes to a lot more then divs so I tried this.. var allLinksWithDivAndClass = _doc.DocumentNode.SelectNodes("//*[@class=\"float\"]"); But that doesn't handle the cases where you add multiple classes and "float" is just one of them like this.. class="className float anotherclassName" Is there a way to handle all of this? I basically want to select all nodes that have a class = and contains float.
