  • unwanted space before and after nested html table using Internet Explorer 8

    - by John
    I have an html table nested in an html table cell. I want the nested table to use the full size of the cell it is nested in. When I use firefox or google chrome I get the result I want but when I use Internet Explorer 8 (even if I use td style="height="100%") the height of the nested cell depends on it's content. As a result I get whitespace before and after my nested table.

  • Getting minimum - Min() - for DateTime column in a DataTable using LINQ to DataSets?

    - by Jay Stevens
    I need to get the minimum DateTime value of a column in a DataTable. The DataTable is generated dynamically from a CSV file, therefore I don't know the name of that column until runtime. Here is code I've got that doesn't work... private DateTime GetStartDateFromCSV(string inputFile, string date_attr) { EnumerableRowCollection<DataRow> table = CsvStreamReader.GetDataTableFromCSV(inputFile, "input", true).AsEnumerable(); DateTime dt = table.Select(record => record.Field<DateTime>(date_attr)).Min(); return dt; } The variable table is broken out just for clarity. I basically need to find the minimum value as a DateTime for one of the columns (to be chosen at runtime and represented by date_attr). I have tried several solutions from SO (most deal with known columns and/or non-DateTime fields). What I've got throws an error at runtime telling me that it can't do the DateTime conversion (that seems to be a problem with Linq?) I've confirmed that the data for the column name that is in the string date_attr is a date value.

  • Auto-(un)boxing fail for compound assignment

    - by polygenelubricants
    Thanks to the implicit casting in compound assignments and increment/decrement operators, the following compiles: byte b = 0; ++b; b++; --b; b--; b += b -= b *= b /= b %= b; b <<= b >>= b >>>= b; b |= b &= b ^= b; And thanks to auto-boxing and auto-unboxing, the following also compiles: Integer ii = 0; ++ii; ii++; --ii; ii--; ii += ii -= ii *= ii /= ii %= ii; ii <<= ii >>= ii >>>= ii; ii |= ii &= ii ^= ii; And yet, the last line in the following snippet gives compile-time error: Byte bb = 0; ++bb; bb++; --bb; bb--; // ... okay so far! bb += bb; // DOESN'T COMPILE!!! // "The operator += is undefined for the argument type(s) Byte, byte" Can anyone help me figure out what's going on here? The byte b version compiles just fine, so shouldn't Byte bb just follow suit and do the appropriate boxing and unboxing as necessary to accommodate?

  • Why is the ( ) mandatory in the SQL statement select * from gifts INNER JOIN sentgifts using (giftID

    - by Jian Lin
    Why is the ( ) mandatory in the SQL statement select * from gifts INNER JOIN sentgifts using (giftID); ? The ( ) usually is for specifying grouping of something. But in this case, are we supposed to be able to use 2 or more field names... in the example above, it can be all clear that it is 1 field, is it just that the parser is not made to bypass the ( ) when it is all clear? (such as in the language Ruby).

  • Did Visual Studio 2010 break "Project Dependencies" between C++ projects?

    - by Roger Lipscombe
    In Visual Studio 2008, if I had a solution containing multiple C++ projects, I could make them depend on each-other and correctly link by using the "Project Dependencies" option. This fixed up the build order and also made (e.g.) the main application project link against the static library outputs. In Visual Studio 2010, this doesn't seem to work. Did Visual Studio 2010 change the way this works?

  • How can I make sure the Sphinx daemon runs?

    - by Ethan
    I'm working on setting up a production server using CentOS 5.3, Apache, and Phusion Passenger (mod_rails). I have an app that uses the Sphinx search engine and the Thinking Sphinx gem. According to the Thinking Sphinx docs... If you actually want to search against the indexed data, then you’ll need Sphinx’s searchd daemon to be running. This can be controlled using the following tasks: rake thinking_sphinx:start rake ts:start rake thinking_sphinx:stop rake ts:stop What would be the best way to ensure that this takes place in production? I can deploy my app, then manually run rake thinking_sphinx:start, but I like to set things up so that if I have to bounce the server, everything will come back up. Should I put a call to that Rake task in an initializer? Or something in rc.local?

    I have a local server which needs to make changes to a virtual hosts apache config file and then restart apache so the new config takes effect. Can PHP do this?

  • ASP.NET MVC 2 Areas, Strange routing behavior

    - by user137348
    I've created an Area named "Admin". I've created also a controller(Pages) and a view(List) in this areas. When I run my app and enter the url "/Admin/Pages/List" I'm getting an The resource cannot be found error. When I enter /Pages/List, the Action method is hit but the view is not found,because the app is searching in wrong directories ~/Views/Pages/List.aspx ~/Views/Pages/List.ascx ~/Views/Shared/List.aspx ~/Views/Shared/List.ascx the view is in /Admin/Pages/List. My routing conf for Admin area: public class AdminAreaRegistration : AreaRegistration { public override string AreaName { get { return "Admin"; } } public override void RegisterArea(AreaRegistrationContext context) { context.MapRoute( "Admin_default", "Admin/{controller}/{action}/{id}", new { controller= "Pages",action = "Index", id = "" } ); } }

  • svn:switch doesn't work with relative svn:external?

    - by sray
    We have a subfolder that is a relative svn external (../project/subfolder). In a fresh trunk checkout it points to (...TRUNK/project/subfolder) and in a fresh branch checkout it points to (...BRANCH/branchName/project/subfolder). But if you do a switch on the project containing the subfolder, the subfolder stays pointing at TRUNK. Alternately if you do a BRANCH checkout and switch to TRUNK it stays pointing at BRANCH. Shouldn't an svn:switch update relative externals? Is there some sort of recursive svn:switch I should be running?
