• What does this mean?

  - by LeonixSolutions

  I found this in some code examples while googling : $sql = 'INSERT INTO users (username,passwordHash) VALUES (?,?)'; it's new to me, but I would guess that it a substitution method and equivalent to $sql = "INSERT INTO users (username,passwordHash) VALUES ($username,$passwordHash)";` or $sql = 'INSERT INTO users (username,passwordHash) VALUES (' . $username . ',' . $passwordHash . ')';` would that be correct? Is it an actual PHP syntax, or was he just trying to simplify his example?

• Convert webpage to image from ASP.NET

  - by Nissan Fan

  I would like to create a function in C# that takes a specific webpage and coverts it to a JPG image from within ASP.NET. I don't want to do this via a third party or thumbnail service as I need the full image. I assume I would need to somehow leverage the webbrowser control from within ASP.NET but I just can't see where to get started. Does anyone have examples?

• Authoritative Excel range syntax reference

  - by olefevre

  Sorry if this has been asked before but I can't find it. I am looking for an authoritative description of all valid strings that can be used as a reference, e.g., "A1:C5", "$A:$A", $A2" etc etc. That seems a pretty basic thing yet I've wasted hours trying to locate it. All I can find is a swamp of "helpful" examples but no reference.

• Creating semaphores with unmanaged code in C++

  - by Dororo

  I've been using the MSDN Library to create semaphores, located at: http://msdn.microsoft.com/en-us/library/system.threading.semaphore.aspx However, the examples are using Managed code (requires /clr), and I need to use Unmanaged code because FreeType doesn't like working with Managed code it seems. How would I go about creating 2 simple threads which use a semaphore if I'm using unmanaged code? Many thanks for your help.

• MySQL - Add Values In Query And Return As Single Value

  - by Sjwdavies

  I'm trying to query a database, and return a set of values. Part of the data i'm trying to return is an insurance premium breakdown. Is it possible to run a query, that selects multiple fields, then adds then and returns them as a single value? I've seen SUM() but the examples i've seen show it as adding up the results of an entire field - where as i need it to add specific fields for each row returned. Any help is much appreciated.

• What is operator<< <> in C++?

  - by Austin Hyde

  I have seen this in a few places, and to confirm I wasn't crazy, I looked for other examples. Apparently this can come in other flavors as well, eg operator+ <>. However, nothing I have seen anywhere mentions what it is, so I thought I'd ask. It's not the easiest thing to google operator<< <>( :-)

• Why does trying to understand delegates feel like trying to understand the nature of the universe?

  - by Kin

  I've read two books, tons of examples. They still make next to no sense to me. I could probably write some code that uses delegates, but I have no idea why. Am I the only one with this problem, or am I just an idiot? If anyone can actually explain to me when, where, and why I would actually use a delegate, I'll love you forever.

  - by stas

  I want to make a website that will have multiple pages, but because of a unique navigation bar, I cannot simply link to a new file for each page. What is the best way to accomplish this.

• Where is comprehensive documentation on Android's XML shapes?

  - by Daniel Lew

  I've been looking around for this for a long time but can never seem to find it in the Android documentation. There's all sorts of advanced things I see, but I can never find any solid documentation - there's the shapes package, but it provides no insight on how to use them in xml. The best I can do so far is finding other people's examples. Is there some magical documentation that exists for the XML shapes?
