Over the past year I've been (re-)learning how to use Visual Studio 2008. I did a lot of work in the 90's and early 00's with Visual Studios 5, 6, and 2003, but then I had a few years away from Windows development, and I've had limited experience with .NET development. So I'm constantly discovering "new things" about Visual Studio that my coworkers already know.
One nifty feature of Visual Studio is "code snippets", which are basically little bits of code that can be quickly inserted into a source file using Intellisense. The inserted code includes placeholders that can be replaced with whatever you need. For example, if you are typing away in a C# source file and type the keyword
for, you'll see the Intellsense window pop up with "for" as the selected item, and if you hit the Tab key a couple of times a complete
for statement with braces, a loop variable, and everything will be inserted. You can then hit Tab to move to the loop variable name (in case you don't like
i) and again to go into the loop body.
(Other IDEs have similar features, calling them abbreviations, macros, etc. You don't need to tell me that Visual Studio isn't magically unique.)
Visual Studio has a whole bunch of these snippets built in, but you can also define your own by writing an XML file and saving it where Visual Studio can find it. For example, here is a snippet I wrote to quickly insert
<?xml version="1.0" encoding="utf-8" ?>
<Description>Creates a String.Format() call</Description>
<ToolTip>Replace with format string</ToolTip>
<ToolTip>Replace with arguments</ToolTip>
Just save this as a file called
StringFormat.snippet in your
Documents\Visual Studio 2008\Code Snippets\Visual C#\My Code Snippets folder. (You can specify another location using the Code Snippets Manager in the Tools menu.) Then, when editing a C# source file, if you type
sf and hit Tab a couple of times, this will magically appear in your code:
The format placeholder will be selected, so you can replace it with your format string, then hit Tab and the arguments placeholder will be selected, so you can replace it. You can keep hitting Tab to go back and forth between the placeholders. When finished, hit Return and the cursor will go to the end of the line.
Alas, snippets only work for C#, Visual Basic, and XML editing. Most of my work is in C++, so I have to keep writing code the old-fashioned way there (or use macros).
Note that I have been talking about Visual Studio 2008. "Why aren't you using Visual Studio 2010?" some will ask. Shut up.
