Adding and Removing Global Variables

The Variables view can also display global variables used by the program. Right-click in the Variables view and select the Add Global Variables menu option to open the Global Variables dialog. There you can select one or more global variables to display in the Variables view, clickiing OK when done.

Removing Global Variables

Right-click in the Variables view and select the Add Global Variables menu option to open the Global Variables dialog. Locate and uncheckmark the global variable to stop displaying, then click OK. This removes the selected global variable from the variables list.

Viewing Variables

The Variables view allows manipulation of project variables and the variable hierarchy used in the source code. For example, you can change the variable format, change a variable value, add watch expressions, or add global variables.

Figure 1 shows the Variables view with Show Type Names option enabled. The default view shows the variables list and include the Name and Value for all the variables within scope. In addition, when you select a variable its value is also shown in a different pane within the view.

In addition, use Show All Variables to toggle between showing only those variables that are in scope and live or show all local variables, even if redundant. With this option on you will see all of the variables including the multiple defined variables like “i” for your loops and ones that may no longer have accurate values.

You create a watchpoint to monitor a value in a specified memory location. The debugger halts program execution on the line of source code that triggered the watchpoint. This is different than a breakpoint, which halts program execution prior to executing the line of source code on which the breakpoint is set.

Setting watchpoints

Right-click in the Breakpoints view and choose the Add Watchpoint (C/C++)... command to open the Add Watchpoint window. A watchpoint suspends program execution when the memory location that you specify is accessed with a write or read operation and it's based on the access setting. Use the Add Watchpoint window to specify the memory location, its memory size, unit size, and define whether the watchpoint triggers on a read, write, or on both operations. Watchpoints can also be added directly in the Variables, Outline, and the Memory Rendering views.
