• VirtualStringTree hide node(s)

  - by michal

  Hi, is that possible to hide specific nodes in VirtualStringTree? I'm implementing "filtering" feature (the VST acts as a list with columns), and I'd like to avoid reloading content each time the filter is changed - instead, much faster would be to tell VST not to render specific items ... any solutions?

• RegCreateKeyEx - does it update the returned handle on failure?

  - by Permaquid

  MSDN documentation seems silent on whether RegCreateKeyEx ever updates the value of the handle referred to by its second-last parameter when it fails. My tests have only shown it not to update this - i.e., I set h = 0 before the call, pass &h to a call to RegCreateKeyEx to open a non-existent key, and see h = 0 after the call. Does anyone know of any situation in which the handle would be changed?

• How can I detect if a request and response cookies are different?

  - by Malcolm Frexner

  I need to detect if a request cookie - value is different from a response cookie - value. Its not as easy as: if(cookiesArePresent) { bool isDifferent = HttpContext.Current.Response.Cookies[".ASPXANONYMOUS"].value == HttpContext.Current.Response.Cookies[".ASPXANONYMOUS"].value; } But I read that changing the Response.Cookies changes the Request.Cookies. That would mean they are always the same if HttpContext.Current.Response.Cookies[".ASPXANONYMOUS"] was changed. Is there an easy way around this? http://chance.lindseydev.com/2009/04/aspnet-httprequestcookies-and.html

  - by user300371

  I am currently building a site and all the books I have read on PHP so far are just on functionality and not much on security. Is there a book that deals specifically with making your code/site secure? I don't want to go public and the next day have all my code changed or my database erased by SQL injection. thanks

• Calculating average (AVG) and grouping by week on large data set takes too long

  - by caioiglesias

  I'm getting average prices by week on 7 million rows, it's taking around 30 seconds to get the job done. This is the simple query: SELECT AVG(price) as price, yearWEEK(FROM_UNIXTIME(timelog)) as week from pricehistory where timelog > $range and product_id = $id GROUP BY week The only week that actually gets data changed and is worth averaging every time is always the last one, so this calculation for the whole period is a waste of resources. I just wanted to know if mysql has a tool to help out on this.

• Default.aspx issue with IIS 6.0 and .Net 4?

  - by Amitabh

  We have deployed a .net 4 asp.net site on IIS 6.0. Default.aspx is configured as one of the default document. When we access the site using the following url http://testsite We expect it to render http://testsite/Default.aspx But instead we get 404 Not found error. We did not had this issue when it was deployed on .Net 2.0. Only thing that has changed on the server is that we use .Net 4 instead of .Net 2.

• Best way to send floating point numbers from .NET to Java and back

  - by Evgeny

  I'm writing a .NET application that will make an RPC call to a Java application (via a message queue). The data sent in both directions will be large arrays of floating-point numbers. What is the best way to serialize them to send them across the wire? I'd like something more compact than text, but architecture-independent as the server may not be an x86 machine. The Java application can be changed as needed.

• Is it safe to modify CCK tables by hand?

  - by LanguaFlash

  I'm not intimately familiar with CCK but I have a one-time custom setup and know that I could get some performance gains if I created indexes and changed the field type and length of some of the fields in my CCK table. Is it save to modify this table at all or will I end up destroying something in the process? Thanks

• How do I make defensive copy of an object?

  How do I make defensive copies of a Mutable Object which contains a mutable field in an Immutable Object? class ImmutableObject { private final MutableObject immutable_field; ImmutableObject(MutableObject y) { this.immutable_field = y; } MutableObject return_immutable_field() { return immutable_field; } } class MutableObject { public int mutable_field; } The MutableObject does not have a constructor that lets me set the field. The MutableObject's current state should be captured in the Immutable Object and never changed.

  Hi there, I'm trying to get Netbeans PHP to let me write braces in a new line instead of the same line, I mean like this: if($something == TRUE) { // some code here } However, when I write if($something == TRUE) then hit enter, Netbeans places the cursor incorrectly in the new line, like this: if($something == TRUE) { // some code here } I've already changed the braces placement option to be "New Line", but this still doesn't work properly.
