• Using ASP.NET Redirect without string URL?

  - by David Dietrich

  For instance, what I have right now is the following: Page.Response.Redirect("Default.aspx", false); Needing to hardcode the string just seems odd to me. The Default.aspx page is already in my project. So is there a way to do the redirect something like the following: Page.Response.Redirect(Default.aspx, false); Where Default.aspx is just the web form. I'd think that this way it would be obvious if there was a problem such as you deleted the web form but didn't update the redirects. Is this possible? Or is there another way entirely I should be looking at this? I suppose I could do something with a static property on the class, but I am wondering if there is a built in thing for this?

• Combining Content Data in Google Analytics

  - by David Csonka

  When I first start one of my Wordpress blogs, I had the permanent URL for each post include the date of posting. The slug format looked like this: /blog/2010/01/25/this-is-my-article/ Later on, I changed it so that the date was not included in the permanent URL, like this: /blog/this-is-my-article/ and setup a redirect plugin to make sure that users would get to the page they wanted until the site was re-indexed. In Google Analytics, when I review the stats for content I now have multiple records for what is essentially the same page. ie: Top Content List: 45 Pageviews- /blog/this-is-my-article/ 24 Pageviews- /blog/2010/01/25/this-is-my-article/ 33 Pageviews- /blog/some-other-article/ Is there any way to combine those records somehow?

• Union and order by

  - by David Lively

  Consider a table like tbl_ranks -------------------------------- family_id | item_id | view_count -------------------------------- 1 10 101 1 11 112 1 13 109 2 21 101 2 22 112 2 23 109 3 30 101 3 31 112 3 33 109 4 40 101 4 51 112 4 63 109 5 80 101 5 81 112 5 88 109 I need to generate a result set with the top two(2) rows for a subset of family ids (say, 1,2,3 and 4) ordered by view count. I'd like to do something like select top 2 * from tbl_ranks where family_id = 1 order by view_count union all select top 2 * from tbl_ranks where family_id = 2 order by view_count union all select top 2 * from tbl_ranks where family_id = 3 order by view_count union all select top 2 * from tbl_ranks where family_id = 4 order by view_count but, of course, order by isn't valid in a union all context in this manner. Any suggestions? I know I could run a set of 4 queries, store the results into a temp table and select the contents of that temp as the final result, but I'd rather avoid using a temp table if possible. Note: in the real app, the number of records per family id is indeterminate, and the view_counts are also not fixed as they appear in the above example.

• Notepad++ regular expression find and replace $_REQUEST with $_GET but a more secure

  - by David

  What I am doing is replacing, in a large program, all $_REQUEST['var'] and mysql_escape_string($_REQUEST['var']) with either the 1st or 2nd line below the dotted line. Now, I have figured out this much of the regular expression but I would like to make it simpler. Instead of having to run the top one first then the 2nd one I would like to just run one all together. I tried this but it did not work. (mysql_escape_string\()*$_REQUEST\[\'([^']*)\'\]\)(\)*) So below is what works but again have to do it twice. $_REQUEST\[\'([^']*)\'\] mysql_escape_string\($_REQUEST\[\'([^']*)\'\]\) (isset($_GET['\1'])?mysql_real_escape_string($_GET['\1']):false) (isset($_POST['\1'])?mysql_real_escape_string($_POST['\1']):false) ============================ Update: Yeah, after some research I figured out that Notepad++ does not support most regular expressions. I guess one additional step can not hurt a person. It's just laziness. *NOTE: BUT if anyone wants to try feel free to comment. At least it is just 2 steps and not 20.

• Designers, Expression or SharePoint Designer, and real source control

  - by David Lively

  I'm trying desperately to move from VSS to a real source control system. Options include TFS and SVN. My designers need to keep their ability to modify source files and instantly preview their changes in a browser without having to commit their changes. Using FPSE with VSS, this works flawlessly, since saving a file causes the copy in the working folder on the dev server to be updated, so they can just save and refresh their browser which is pointed at the dev server. The site in question consists of 350k+ lines of classic ASP code and some new ASP.NET MVC. They only need to be able to modify views within the MVC code, not C#. Though Expression includes a version of Cassini for local debugging, Cassini does not support classic ASP. Surely someone has solved this problem before. It can't be necessary to install IIS on each designer's machine (this is absolutely untenable). I need a way to have a common working folder on a dev webserver updated whenever someone saves a file locally, just like using FPSE. I'd rather not write an FPSE proxy that knows how to talk to TFS/SVN. Any suggestions? (I know I've asked this question in the past, but I haven't yet found a solution.)

• Limiting what a .net plugin can access

  - by David Hogue

  I have a web application that can load plugins through reflection. It currently uses Assembly.LoadFrom() and Activator.CreateInstance() to get this done. Right now plugins are loaded into the same AppDomain and have access to anything in my app and anything my app could access. What I'm looking for is a way to limit what classes and methods the plugin can access for security purposes. I want to have all of my classes and methods throw an exception when called unless they are whitelisted. I'd be whitelisting basically all the functions in an API class and a few data transfer objects. I also don't want the plugin to be able to access the filesystem or the database on it's own. I think I can do that with trust levels in a separate AppDomain though. Does anyone out there have any good ideas or resources? Is this something that could be done with Code Access Security or the new Security-Transparent Code features in .net 4?

• How to assemble a WAV file?

  - by David

  I'm doing an educational project in which 1) I record voice commands on a separate device and after appropriate processing etc... 2) I send 16-bit samples encapsulated in UDP packets over Ethernet to the PC. After receiving the packets and "extracting" data (samples) from them, I need to assemble the samples to a WAV file. Any example code? Any suggestions?

• What is the worst source control you have used? [closed]

  - by David Liddle

  There are many discussions about what people's favourite source control is (subversion, mercurial ...). But what source control systems have you used that you certainly wouldn't recommend? And more beneficial, how would you go about promoting change in the business to a new source control system? A few years ago I developed using a source control system called Synergy. There were two Synergy experts in the company that constantly had to help the developers do check-ins/outs and merges were especially difficult. What would be your steps of migrating to a better source control. Would you host everything internally or pay for services such as github?

• Refactoring if/else logic

  - by David

  I have a java class with a thousand line method of if/else logic like this: if (userType == "admin") { if (age > 12) { if (location == "USA") { // do stuff } else if (location == "Mexico") { // do something slightly different than the US case } } else if (age < 12 && age > 4) { if (location == "USA") { // do something slightly different than the age > 12 US case } else if (location == "Mexico") { // do something slightly different } } } else if (userType == "student") { if (age > 12) { if (location == "USA") { // do stuff } else if (location == "Mexico") { // do something slightly different than the US case } } else if (age < 12 && age > 4) { if (location == "USA") { // do something slightly different than the age > 12 US case } else if (location == "Mexico") { // do something slightly different } } How should I refactor this into something more managable?

• Calling C++/CLI Method with System::DateTime parameter requires 'ValueType' as a parameter?

  - by David Ipsen

  I'm attempting to call a method written in C++/CLI from C#. The C++/CLI code is used to update a TIMESTAMP column in an Oracle database, given a record ID and the System::DateTime object which is the .NET compatible data type for Oracle's TIMESTAMP type. The method I am calling has the following prototype: bool ChangeJobUpdateDate (int jobIdIn, System::DateTime^ updateDateIn) I've added a reference to this DLL project in a test project that I made; I'm writing the tests in C#. However, when I try to call this method from the C# unit test project, the function appears to have the following method declaration (via intellisense): bool ChangeJobUpdateDate (int jobIdIn, ValueType updateDateIn) I'm admittedly not that familiar with C++/CLI, so is there something I'm missing?

• Regex to split a string (in Java) so that spaces are preserved?

  - by david

  I need to split a string (in Java) into individual words ... but I need to preserve spaces. An example of the text I need to split is something like this: ABC . . . . DEF . . . . GHI I need to see "ABC", " . . . .", "DEF", ". . . .", and "GHI". Obviously splitting on the space character \s isn't going to work, as all the spaces get swallowed up as one space. Any suggestions? Thanks

• How to call a custom php file on magento product page

  - by David

  if getChildHtml('product_type_data') ? maps directly to catalog/product/view/type/simple.phtml by default, how do I map to my own file? If I wanted to create a file that would produce a small image to place on the product page, right under "availability" how would I tell magento to map to where I have put the file? From what I understand getChildHtml('product_type_data') ? defaults to the file path: catalog/product/view/type/simple.phtml so how can I customize the magento defaults and tell it to map to my custom files i've created? I hope I have explained this well enough, if not, please let me know and I will try to explain more. Any help or guidance would be awesome. Thanks.

• How to get and modify a property value through a custom Attribute?

  - by David G

  I want to create a custom attribute that can be used on a property like: [TrimInputString] public string FirstName { get; set; } that will be functional equivalent of private string _firstName public string FirstName { set { _firstName = value.Trim(); } get { return _firstName; } } So basically every time property is set the value will be trimmed. How do I get the value parsed, modify that value and then set the property with the new value all from within the attribute? [AttributeUsage(AttributeTargets.Property)] public class TrimInputAttribute : Attribute { public TrimInputAttribute() { //not sure how to get and modify the property here } }

• Waiting for a subset of threads in a Java ThreadPool

  - by David Semeria

  Let's say I have a thread pool containing X items, and a given task employs Y of these items (where Y is much smaller than X). I want to wait for all of the threads of a given task (Y items) to finish, not the entire thread pool. If the thread pool's execute() method returned a reference to the employed thread I could simply join() to each of these Y threads, but it doesn't. Does anyone know of an elegant way to accomplish this? Thanks.
