How do I find all expression "variable = variable;" in the Visual Studio 2008?

Question

I want to find all expression variable = variable; in my source files. I use Visual Studio 2008.

The variable is any variable, for example x, i, k123, incr15.

Samples:

x = x;           // Should find
x = y;           // No match
ss12 = ss12;     // Should find
ss12 = ss12 + 1; // No match

Answer 1

use regular expression search.

e.g.: \w* = \w*

Answer 2

Have you tried the "Find all References" feature on the context menu?

Answer 3

Use 'Find in Files' functionality with 'regular expressions' selected.

Something like this should do it:

\w+\s*=\s*\w+;

Answer 4

Use the 'Find In Files' search.

Select/highlight your expression, then press CTRL + SHIFT + F and then click on 'Find In Files' button on the 'Find and Replace' dialog that opens

Answer 5

Use the Find-dialog with regex ...

{:a+} = \1

will do the trick.
:a is any alphanumeric character
\1 is a backreference to everything included in {}

See here for more infos.

EDIT - in reply to the comment:

^:b*{:a+}:b*=:b*\1;

^ is the beginning of a line
:b is tab/space

EDIT2: As Kobi wrote, you should maybe use :i instead of :a

Answer 6

Try:

^:Zs+{:i}:Zs*=:Zs*\1;

It sould also be said that such a statement gives a compilation warning:

Assignment made to same variable; did you mean to assign something else?
