Display the current line and column numbers in Visual Studio 2010

Have you tried this?

Tools->Options->Environment->General->Show status bar

If there's anyone with version 16.4.x or later wondering where it went, it got moved from the Status Bar to the bottom right of the editor window.

Please note that Col (column) is omitted from the status bar when it has the same value as Ch (character), as is the case when using spaces for indentation. Spaces will always increment Col and Ch together, whereas tabs will increment the Ch value by one while incrementing the Col value by whatever the tab width is set to be (e.g. 4).

Examples:

Tabs

--->--->Hello, World!
                     ^

Ch: 16    Col: 22

Spaces

········Hello, World!
                     ^

Ch: 22    Col: 22

If your cursor is at the tail end of the line, the Ch and Col values reflect the 1-indexed position denoted by the caret. Col would be omitted from the status bar in the second example.

In case anyone else has the same problem as me, I found that the line number and column didn't show up in the status bar until I hid some of the other information that was there - my extensions added a lot of items.

Right-clicking on the status bar gives a list of what's being shown there (excluding default stuff like columns, confusingly), and you can untick things to hide them. Untick enough, and line and column numbers should come back!
