• Refactoring many nested ifs or chained if statements

  - by Icarus

  Hi, I have an object with large number of similar fields (like more than 10 of them) and I have to assign them values from an array of variable length. The solution would be either a huge nested bunch of ifs based on checking length of array each time and assigning each field OR a chain of ifs checking on whether the length is out of bounds and assigning each time after that check. Both seem to be repetitive. Is there a better solution ?

• Is there a good way of displaying required field indicators when using DataAnnotations in MVC 2?

  - by Jeremy Gruenwald

  I've got validation working with DataAnnotations on all my models, but I'd like to display an indicator for required fields on page load. Since I've got all my validation centralized, I'd rather not hard-code indicators in the View. Calling validation on load would show the validation summary. Has anyone found a good way of letting the model determine what's required, but checking it upon rendering the view, similar to Html.ValidationMessageFor?

• Best way to detect duplicates when using Spring Hibernate Template

  - by Dean Povey

  We have an application which needs to detect duplicates in certain fields on create. We are using Hibernate as our persistence layer and using Spring's HibernateTemplate. My question is whether it is better to do so an upfront lookup for the item before creating, or to attempt to catch the DataIntegrityViolation exception and then check if this is caused by a duplicate entry.

• Creating a structure from bytes with ctypes and IronPython

  - by Adal

  I have the following CPython code which I now try to run in IronPython: import ctypes class BarHeader(ctypes.Structure): _fields_ = [ ("id", ctypes.c_char * 4), ("version", ctypes.c_uint32)] bar_file = open("data.bar", "rb") header_raw = bar_file.read(ctypes.sizeof(BarHeader)) header = BarHeader.from_buffer_copy(header_raw) The last line raises this exception: TypeError: expected array, got str I tried BarHeader.from_buffer_copy(bytes(header_raw)) instead of the above, but then the exception message changes to TypeError: expected array, got bytes. Any idea what I'm doing wrong?

• code style for private methods in c#

  - by illdev

  I just found out, that it seems a common pattern to user UpperFirstLetterPascalCase() for private methods. I for myself, find this completely inconsistent with naming rules of private instance fields and variables and I find it difficult to read/debug, too. I would want to ask, why using a first upper letter for methods could be a better choice than a first lower (doThis())? Just out of curiosity...

• How to make an Inputfield change its design when active?

  - by Opoe

  Hi all, Let's say my background color is red. I want the input textfield to appear red, but when you click inside the input field to type it becomes a regulad textfield. And ofcourse when you are not active in the input field it should be back to its original state (red). Its actually something you see quite often. I thought of using toggleclass? My input fields are all appended with jQuery Thanks in advance

• Orphaned SQL Recordsets/Connections with IIS

  - by Damian

  I have an IIS 6 site running on Windows 2003 Server x86 with MS SQL2005 Enterprise edition running ASP Classic (no choice). The site runs very fast with about 8000 page views per hour. All of my SQL tables are indexed and I have used the profiler to check my queries, the slowest of which is only about 10-15ms. I have autoshrink disabled, autogrow is set to 250mb, database is 2gb with 800mb of free space. My problem is that every now and then the site will slow to a crawl for no reason. Pages that just have a simple 'connect to databse and increment a hit counter' work ok, but more SQL intensive pages that normally execute in about 60ms take 25,000ms to run. This happens for about 30 seconds and then goes away. I was having an issue with orphan recordsets and connections due to the way I was releasing them. I have fixed this up and the issue is much better, but I am still getting them. Is there a way with permon, etc. to track when SQL Server or Windows closes these Orphan connections? At least if I can monitor the issue I will know if I am making progress or if I am even looking at the right things. Is there anything else I might be missing? Thank you!

• How to SELECT the last 10 rows of an SQL table which has no ID field?

  - by Edward Tanguay

  I have an MySQL table with 25000 rows. This is an imported CSV file so I want to look at the last ten rows to make sure it imported everything. However, since there is no ID column, I can't say: SELECT * FROM big_table ORDER BY id DESC What SQL statement would show me the last 10 rows of this table? The structure of the table is simply this: columns are: A, B, C, D, ..., AA, AB, AC, ... (like Excel) all fields are of type TEXT

• Using C# with Crystal Reports, How Can I Create 4-Up Subreports?

  - by C. Griffin

  The simplest example that I can provide for what I want to do is this: I need to create a Report, whose only requirement is that I have (4) of the same subreport on the page (imagine 4 portrait-oriented post cards on a page), each quadrant using a separate row from my datatable, yet all 4 are identical in terms of fields. If there are more than 4, it needs to carry over to a new page with the same format. I'm using C# and the built-in Crystal Reports Basic for the task.
