How can I take a byte array of a TIFF image and turn it into a System.Drawing.Image object? |
|c#|.net|image|tiff| |
I have a `byte[]` array, the contents of which represent a TIFF file (as in, if I write out these bytes directly to a file using the `BinaryWriter` object, it forms a perfectly valid TIFF file) and I'm trying to turn it into a System.Drawing.Image object so that I can use it for later manipulation (feeding into a multi... |

User Interface Controls for Win32 |

I see many user interface control libraries for .NET, but where can I get similar stuff for win32 using simply C/C++?
Things like prettier buttons, dials, listviews, graphs, etc.
Seems every Win32 programmers' right of passage is to end up writing his own collection. :/
Thanks,

What's the best way to build a string of delimited items in Java? |

While working in a Java app, I recently was needing to assemble a comma-delimited list of values to pass to another web service without knowing how many elements there would be in advance. The best I could come up with off the top of my head was something like this:

Whilst its been years since I have used spring, and I can't say I am a fan of it, I know that the App Fuse tool ([https://appfuse.dev.java.net/][1]) has been helpful to help people bootstrap in terms of generating all the artifacts you need to get going.

Instead of making the control public, you can create a property controlling its visibility:
public boolean ControlIsVisible
{
get { return control.Visible; }
set { control.Visible = value; }
}
This creates a proper accessor to that control that won't expose the control's whole se... |
The first is not working of course. The controls on a form are private, visible only for that form by design.
To make it all public is also not the best way.
If I would like to expose something to the outer world (which also can mean an another form), I make a public property for it.

Focus first on the heart of Spring: Dependency Injection. Once you see all the ways that DI can be used, then start thinking about the more interesting pieces like AOP, Remoting, JDBC Templates etc. So my best bit of advice is let your use of Spring grow out from the core.

where lastUpdate > getDate() -31

A "connection reset" does *not* indicate that the partner closed the connection, but that it *abruptly killed* the connection without calling close, often by the process crashing.
