Maybe you forgot to associate the tooltip with the control using [SetToolTip][1].

It depends on the size of the project. The throughput is low and the latency is high, so you're going to get hit every which way, but due to the latency you'll be hit harder if you have a lot of little files rather than a few large ones.

It depends mostly on how much the respository is used. With one user checking in once a day and a branch/marge/etc operation once a week you probably don't need to run it more than once a year.

You could use a service like www.unfuddle.com to set up a free SVN or GIT repository.

Two concerns to keep in mind:
1. Your example involved placing a

Visual studio is being built on top of the [MSBuild][1] configurations files. You can consider *proj and *sln files as makefiles. They allow you to fully customize build process.

You can use nant to build the projects individually thus replacing the solution and have 1 coding solution and no build solutions.

my #1 way to do this, add white space to the top of the web config file, after the xml declaration tag.
It forces the node to re-cache and recompile. We even have a page deep in the admin called Flush.aspx that does it for us. |
While it's technically possible, it's not a very friendly solution within Visual Studio. It will be fighting you the entire time.

I have not yet developed using WPF.. But I would assume that its the same as most other applications in that you want to keep the UI code as light as possible.. A number of design patterns may be used in this such as the obvious [MVC](http://en.wikipedia.org/wiki/Model-view-controller) and [Façade](http://en.wikipedia.... |
If you're fine with using the std c library:
#include <sys/stat.h>
off_t fsize(char *file) {
struct stat;
if (stat(file, &stat) == 0) {
return stat.st_size;
}
return 0;
} |
Matt's solution should work, except that it's C++ instead of C, and the initial tell shouldn't be necessary.
unsigned int fsize(char* file
{
FILE * f = fopen(file, "r");
fseek(f, 0, SEEK_END);
return (unsigned int)ftell(f);
}
Fixed your brace for you, too. ;) |

It always comes down to the right tool for the job, so it really depends on what you are trying to accomplish.

You could try looking into WPF, using Visual Studio and/or Expression Blend. I'm not sure how sophisticated you're trying to get, but it should be able to handle a simple editor. Check out this [MSDN Article](http://msdn.microsoft.com/en-us/library/ms742562.aspx) for more info. |

AFAIK, ANSI C doesn't define threading, but there are various libraries available.

You get '5.6' if you do `str(round(n, 1))` instead of just `round(n, 1)`. |
