Tip: Bookmarks

Posted by Ion Toma on April 17, 2006

Bookmarks can be used to mark places in the code, like the code that you might want to jump back and forward. Bookmarks can be related to task list shortcuts, kind of the same functinality.

The bookmarks can be setup very easy, by pressing CTRL+K, CTRL+K to leave bookmark. For navigation, you can press CTRL+K, CTRL+N to move to the next bookmark, or CTRL+K,CTRL+P for the previous bookmark.

Tip: Word-wrap

Posted by Ion Toma on April 17, 2006

In case we got code that goes too long, we have to scroll out of the screen to see the whole line.
In Visual Studio .NET, there is an option to wrap the text around, we don’t have to scroll horizontal to see the whole line
WordWrap_Image8

To wrap the text around, hit the following combination:
CTRL+R, CTRL+R in .NET 2003
CTRL+E CTRL+W in .NET 2005
Disadvantage: it make the code look a little bit messy.  But working with line numbers, this may be avoided. Tools > Options and select a checkbox that allows to see the line numbers.

Note: this tip can be used also in the case when we have to move the mouse over an error description to be able to see the long line. Just hit CTRL+R CRTL+R in Output pane and the error description will wrap around.

Tip: Add Line Numbers to Your Code-Behind Classes

Posted by Ion Toma on April 17, 2006

Adding Line numbers to your code can be very helpful when discussing the code with someone else. 

LineNo_Image7

How to add line numbers to the code: from Tools menu, select Options, and then the Text Editor / C# or Basic options. Select then the "Line numbers" checkbox om the right-side.

LineNo_Image7i

Also, it works well with word wrap, you can see when a line starts and ends.
Another way to bring lines to your code is using Macro Explorer Tool window; there is a build in macro built-in that allows to turn on/off the line numbers.

Note: the line numbers are in the code, they are just displayed in a column to the left.

Tip: Treat Warnings as Errors

Posted by Ion Toma on April 16, 2006

A warning is a bug in waiting*. Warnings may be acceptable for debug builds, but for a release build, warnings must be always treated as errors. Zero-warnings should be as a rule for programmers, it is easy to ignore warnings, some of them may actually indicate a problem.
Warnings are the compiler's way of saying "this bit of code looks wrong, you better check it out“*. 

Others reasons:

  • It is bad practice to ship code that has compiler warnings in it. The compiler can help the developer, if the compiler generates an warning that means the developer must pay attention to it.
  • The customer may get some examples which contains sources. The warnings generated during compilation make the code look sloppy.

How to set it up: from Project Settings> Configuration Properties select the build setting and change the “treat warnings as errors” settings to true.Then set the warning levels to full, since we want to get all the help from the compiler as possible.

Tip: Custom Tasks List

Posted by Ion Toma on April 16, 2006

Custom task list is a great feature, which provides information about errors, annotations that a developer will leave in code.

There are some default tokens built-in in VS.NET. Example: TODO tokens (to finish some piece of code, etc).
The developer can create custom tokens for bugs, for notes that he/she want to leave to other developers on team that may work on the same code.

How to add CUSTOM TASK LIST TOKENS.
 – Go to  Options, select Task List, then enter a name for the CUSTOM TOKEN and click Add.
