• Create a new output file in ant replace task

  - by Sathish

  Ant replace task does a in-place replacement without creating a new file. The below snippet replaces tokens in any of the *.xml files with the corresponding values from my.properties file. <replace dir="${projects.prj.dir}/config" replacefilterfile="${projects.prj.dir}/my.properties" includes="*.xml" summary="true"/'> I want those *.xml files that had their tokens replaced be created as *.xml.filtered (for e.g.) and still have the original *.xml. Is this possible in Ant with some smart combination of tasks and concepts ?

• Best way to globally set every control's ValidationGroup property in an asp.net?

  - by Steve Flook

  I have a User Control with form items that is re-used considerably throughout a large web application, and up until this point the validation summary upon an invalid form submission is being handled by the .aspx that consumes the User Control. Now I need to set the ValidationGroup property at runtime for each of my form items controls (textboxes, lists, validators, etc). Rather than do it manually by setting each control I'm interested in iterating through all the controls in the User Control, detecting if that control has a ValidationGroup property, and setting it's value that way. Something like this: For Each ctrl As System.Web.UI.Control In Me.Controls ' so now what is the proper way to detect if this control has the ValidationGroup property Next Code sample in vb.net or c# works for me. Many thanks!

• Mysql transactions issue

  - by Stann

  In straight mysql script I'd do transactions like this: START TRANSACTION; SELECT @A:=SUM(salary) FROM table1 WHERE type=1; UPDATE table2 SET summary=@A WHERE type=1; COMMIT; i'm a little confused about how transactions work in PDO. It looks like there are beginTransaction() and commit() methods - so I'm not sure are these just convenience wrappers around staright SQL? or are they doing some more job behind the doors? In other words - are these examples below essentially the same? example 1: $dbh->exec( 'START TRANSACTION' ); //...do some db work here... $dbh->exec( "COMMIT" ); example 2: $dbh->beginTransaction(); //...do some db work here... $dbh->commit();

• How does one declare the type of an Android preference?

  - by David R.

  I have a preferences.xml that looks like this: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <EditTextPreference android:name="Sample" android:enabled="true" android:persistent="true" android:summary="Sample" android:defaultValue="3.0" android:title="Sample" android:key="sample" /> </PreferenceScreen> When I do sp.getString("sample", "3.0"), it works fine and returns a string, but it shouldn't be a string, it should be a float. Running sp.getFloat("sample", 3.0f) throws a ClassCastException because it is a string. What should I put in the XML so that the preference is stored as a float?

• Nested preference screens lose theming

  - by stealthcopter

  I have a preference screen for my application and in the manifest I have given it a theme using: android:theme="@android:style/Theme.Light.WallpaperSettings" However when I nest another preference screen inside this one such as: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" android:title="@string/setting_title" android:key="..."> <PreferenceCategory android:title="@string/title_themes" > <PreferenceScreen android:title="@string/title_themes_opt" > <ListPreference android:key="Setting_BG" android:title="@string/setting_bg" android:summary="@string/setting_bg_summary" android:entries="@array/bg_titles" android:defaultValue="0" android:entryValues="@array/bg_values" /> </PreferenceScreen> </PreferenceCategory> </PreferenceScreen> The nested preference screen loses the theme of the parent. How can this be prevented? Thanks in advance.

• Return value changed after finally

  - by Nestor

  I have the following code: public bool ProcessData(String data) { try { result= CheckData(data); if (TextUtils.isEmpty(result)) { summary="Data is invalid"; return false; } ... finally { Period period = new Period(startTime, new LocalDateTime()); String duration = String.format("Duration: %s:%s", period.getMinutes(), period.getSeconds()); LogCat(duration); } return true; As I learned from this question, the finally block is executed after the return statement. So I modified my code according to that, and in the finally I inserted code that does not modify the output. Strangely, the code OUTSIDE the finally block does. My method always returns true. As suggested, it is not a good idea to have 2 return. What should I do?

• Stored procs breaking overnight

  - by Chad

  We are running MS SQL 2005 and we have been experiencing a very peculiar problem the past few days. I have two procs, one that creates an hourly report of data. And another that calls it, puts its results in a temp table, and does some aggregations, and returns a summary. They work fine...until the next morning. The next morning, suddenly the calling report, complains about an invalid column name. The fix, is simply a recompile of the calling proc, and all works well again. How can this happen? It's happened three nights in a row since moving these procs into production.

• In ASP.NET MVC Should A Form Post To Itself Or Another Action?

  - by Sohnee

  Which of these two scenario's is best practice in ASP.NET MVC? 1 Post to self In the view you use using (Html.BeginForm) { ... } And in the controller you have [HttpGet] public ActionResult Edit(int id) [HttpPost] public ActionResult Edit(EditModel model) 2 Post from Edit to Save In the view you use using (Html.BeginForm("Save", "ControllerName")) { And in the controller you have [HttpGet] public ActionResult Edit(int id) [HttpPost] public ActionResult Save(EditModel model) Summary I can see the benefits of each of these, the former gives you a more restful style, with the same address being used in conjunction with the correct HTTP verb (GET, POST, PUT, DELETE and so on). The latter has a URL schema that makes each address very specific. Which is the correct way to do this?

• How to generate a video signal from Android device via USB?

  - by C.Rivlaldo

  Is it possible to create an application for Android, which can generate a video signal (HDMI or VGA) via USB? Any Android device has miniUSB port. Theoretically it's possible to create a small commutator device on microcontroller or microscheme, which will be a USB-host for Android device. You'll connect Android device with commutator and then connect commutator with monitor. For example, the scheme looks like: Android phone - commutator (USB-host) - TV/Monitor. Summary, I need to connect android phone with TV via miniUSB port. I found soft which can use miniUSB - HDMI cable, but those apps only for Motorolla Droid and HTC Evo. I'll glad to get links to existing apps or projects on that theme, to info about software generation HDMI-signal and connecting Android devices with another devices. Thank you and sorry for my bad english!

• fullcalendar, how to limit the number of events per day in the month view

  - by VNE_Hess

  I have many events on a day, and it works as expected but now looking at the month view, my calendar grid is much taller that expected. I'd like to hide some of these events from the month view, like a summary with a visual que that there are more on this day than can be shown. I can use eventRender and return false, but i would like to know how many events are on a given day, so i can limit the rendering to about 4, then perhaps i would add an event that says " more ... " So the question may be : how to count the events on a given date ? or is this more like a feature request to expose a max counter for month view ? thanks

• Join unrelated tables through a second level connected table

  - by Andy M

  Hello! I have two tables of activities on a page: Views & Comments. Views id timestamp project_id user_id page_id Comments id timestamp project_id user_id page_id comment Pages id project_id title Now pages are related to projects: Projects id account_id title I am trying to create a summary page that combines views and comments ordered by time (so that the most recent views/comments are at the beginning, grouped by projects. Also, only projects for a specific account. So the result could potentially be: Project 1 View 5 (June 20th) View 4 (June 18th) Comment 5 (June 15th) Comment 4 (June 14th) Comment 3 (June 12th) Project 3 View 3 (June 10th) View 2 (June 8th) Comment 2 (June 7th) Project 2 View 1 (June 5th) Comment 1 (June 4th) If you could help with how to do this using SQL (or even doctrine) that would be awesome. Thank you.

• Using reshape + cast to aggregate over multiple columns

  - by DamonJW

  In R, I have a data frame with columns for Seat (factor), Party (factor) and Votes (numeric). I want to create a summary data frame with columns for Seat, Winning party, and Vote share. For example, from the data frame df <- data.frame(party=rep(c('Lab','C','LD'),times=4), votes=c(1,12,2,11,3,10,4,9,5,8,6,15), seat=rep(c('A','B','C','D'),each=3)) I want to get the output seat winner voteshare 1 A C 0.8000000 2 B Lab 0.4583333 3 C C 0.5000000 4 D LD 0.5172414 I can figure out how to achieve this. But I'm sure there must be a better way, probably a cunning one-liner using Hadley Wickham's reshape package. Any suggestions? For what it's worth, my solution uses a function from my package djwutils_2.10.zip and is invoked as follows. But there are all sorts of special cases it doesn't deal with, so I'd rather rely on someone else's code. aggregateList(df, by=list(seat=seat), FUN=list(winner=function(x) x$party[which.max(x$votes)], voteshare=function(x) max(x$votes)/sum(x$votes)))

• Autofiltered List; cross-row formula

  - by Chris Gunner

  I have a large Autofiltered list (~600 rows), with some of the rows being summary rows that I want to use a UDF to display the lowest priority listed in any of the 'child' cells. I can pass to my formula the right cells, but they are no longer correct if the list is re-ordered in any way. Is there a way to give the formula the right cell and have it recognise that I want that row and only ever that row? I can do it with a VLOOKUP to look at a hidden column that lists wether the 'child' row matches the right criteria, but with 600 rows and each parent row requiring about a dozen 'child' cells each, it's too slow.

• String Encoding doesn't ouput all characters

  - by AndroidXTr3meN

  My client uses InputStreamReader/BufferedReader to fetch text from the Internet. However when I save the Text to a *.txt the text shows extra weird special symbols like 'Â'. I've tried Convert the String to ASCII but that mess upp å,ä,ö,Ø which I use. I've tried food = food.replace("Â", ""); and IndexOf(); But string won't find it. But it's there in HEX Editor. So summary: When I use text.setText(Android), the output looks fine with NO weird symbols, but when I save the text to *.txt I get about 4 of 'Â'. I do not want ASCII because I use other Non-ASCII character. The 'Â' is displayed as a Whitespace on my Android and in notepad. Thanks! Have A great Weekend! EDIT* found:   in Wordpad

• Locked visible cells Excel problem

  - by graham.reeds

  I have a problem with an Excel Template in Excel 2007. I need to remove a row from a summary report but the developer who created this report has somehow managed to set it so that only certain number of rows & columns are visible (in case you are interested it is A1:G30) - no headers, no grid, just blue nothingness. Deleting the offending line just peels back the white-ness. I want to change the resolution of the visible grid to A1:G29. I would ask on google but I haven't the foggiest what the tool would be called to do this (if I did I probably wouldn't be asking). Giving generic terms gives very generic results. I've been through every ribbon and came up blank. Help me out my misery - please!

• How to implement partial refresh like facebook like/comments?

  - by shillong

  We have java web application. Summary page will display list of rows. For each row, user can vote and add comments. Vote or add comments will commit immediately and refresh total vote number and comments count. We want to refresh current row instead of whole table just like Facebook does. If need, we can show the list of data with form format (iterator List of data) instead of table format. How to implement this feature base on JSF?

• Calculating percentiles in Excel with "buckets" data instead of the data list itself

  - by G B

  I have a bunch of data in Excel that I need to get certain percentile information from. The problem is that instead of having the data set made up of each value, I instead have info on the number of or "bucket" data. For example, imagine that my actual data set looks like this: 1,1,2,2,2,2,3,3,4,4,4 The data set that I have is this: Value No. of occurrences 1 2 2 4 3 2 4 3 Is there an easy way for me to calculate percentile information (as well as the median) without having to explode the summary data out to full data set? (Once I did that, I know that I could just use the Percentile(A1:A5, p) function) This is important because my data set is very large. If I exploded the data out, I would have hundreds of thousands of rows and I would have to do it for a couple of hundred data sets. Help!

• How do I validate that a list box is not empty (client side)

  - by chris

  I'm working with ASP.NET 3.5. I have a list box that users must add items to (I've written the code for this). My requirement is that at least one item must be added to the listbox or they cannot submit the form. I have several other validators on the page and they all write to a ValidationSummary control. I would like this listbox validation to write to the Validation Summary control as well. Any help is greatly appreciated. Thank you.

• C++ MFC add combo box string item from a widget ID

  - by OzBarry

  I've added a combo box in the gui editor in MSVC 2010 pro in my MFC project. I have a list of strings I am grabbing from an external source and want to add them to my combo box. I've searched for a while, and every post seems to suggest I need to use the CComboBox class, however, I have no idea how to get the class variable from the resource ID of the combobox element in the gui editor. In summary, how do I add a string to my combo box, either using a macro (like CB_ADDSTRING(RESOURCE_ID, "my string");) or using CComboBOx (something like CComboBox::GetObject(RESOURCE_ID)->AddString("blah");). I do not do much win32 api/mfc programming, and just started fiddling around with it.
