• C++ Logger-Should I use an ordinary xml parser?

  - by Jonathon

  I'm working on a logging system for my 2D engine, and I'm confused on how I should go about creating/editing the file, and how I should output that file. I've learned that XML is more of a data carrier rather than a data displayer like HTML is. I've read that I can use XML to HTML converters. One method I've thought about is writing characters to a file in HTML. Clarity on these matters is what I ask of you, stack overflow.

• How to modify TaskDialog's Show() call to be blocking and return a value when closed?

  - by JustABill

  I'm using the WindowsAPICodePack's TaskDialog implementation, but it bugs me that I have to listen to click handlers on its buttons for even the more basic implementations. I'd like to convert/wrap it so that like the old MessageBox it blocks until closed and then returns a value based on what was done. Is there anything I can read for the basics on how to do this? I just have no idea where to even start, as I am admittedly not that familiar with the Win32 underpinnings.

• Javascript array best practice to use [] instead of new array?

• Static Memory allocation & Portability

  - by user332354

  I have read Static Memory Allocation are done during Compile time. Is the 'address allocated' used while generating executables ? Now,I am in doubt that how the memory allocation is handled when the code executable is transferred completely to a new system. I searched for it but I didn't get any answer on Internet.

• Assign query results to MySQL variable

  - by 5un5

  I'm querying a big mysql database with only read privileges, and I'd like to set some slow query results to a variable, 'foo', so I can use them again in other queries. I get, ERROR 1193 (HY000): Unknown system variable '$foo' when I enter: set $foo := (select * from table1 join table2 where bar = 0 group by id); Is there a way to do this with variables, since I don't have privileges to create temporary tables?

• Programming Concepts That Were "Automated" By Modern Languages

  - by Ygam

  Weird question but here it is. What are the programming concepts that were "automated" by modern languages? What I mean are the concepts you had to manually do before. Here is an example: I have just read that in C, you manually do garbage collection; with "modern" languages however, the language itself takes care of it. Do you know of any other, or there aren't any more?

• Inline in aspx, stripping date off of datetime

  - by DJGray

  I think if I just show you the following what I'm asking will make sense. In a link in my aspx, this works: ' title='<%# Container.DataItem["EventTime"].ToString() But the above contains the date portion of the string. This does not work (nor does any variant of it): ' title='<%# Container.DataItem["EventTime"].ToString("hh:mm:ss tt", CultureInfo.InvariantCulture) % Evantually, we want the title/hover for the link to read something like "4:30 PM : @Forbes Field" Everything is working with the exception of the 1/1/1900 being in front of the 4:30 How do I get the date off that EventTime datetime field?

• Visual Studio 2010 - Is it slow for anyone else?

  - by AngryHacker

  I've read a lot of stuff about VS2010 being much more performant than VS2008. When I've finally installed it, I found that it, in fact, is much slower (save for the Add References dialog). For instance, Silverlight projects take twice as long to load, the startup of the IDE itself is much slower, etc... Am I missing something here or is it like this for everyone?

• How to change color of selected references

  - by user272924

  Visual Studio 2010 highlights all references to the same variable (or class) when your cursor is placed over it. with the theme I use highlighted references are white on white - making them virtually impossible to read. what is the name of "display item" in Options- Environment Fonts and Colors that is responsible for that color? changing Plain Text to a darker one partially solves an issue however that also changes color for lots of other stuff on a screen, so ideally would be to change a background for this type of "selection"..

• Is this technically thread safe despite being mutable?

  - by Finbarr

  Yes, the private member variable bar should be final right? But actually, in this instance, it is an atomic operation to simply read the value of an int. So is this technically thread safe? class foo { private int bar; public foo(int bar) { this.bar = bar; } public int getBar() { return bar; } } // assume infinite number of threads repeatedly calling getBar on the same instance of foo.

  In a naive implementation of a thread pool, can a piece of code that is being executed read the data left by some previous code on the stack (if it was running on the same thread instance)? Also, are there any other inherent security issues connected to thread pools?
