15 <h1>Working with variables</h1> |
|
16 |
|
17 <p>During a debug session, you can display variable types, and change |
|
18 or disable variable values.</p> |
|
19 |
|
20 <p>To display variable type names:</p> |
|
21 |
|
22 <ul> |
|
23 <li>In Variables view, click the <b>Show Type Names</b> toggle button.</li> |
|
24 </ul> |
|
25 |
|
26 <p>To change a variable value while debugging:</p> |
|
27 |
|
28 <p>During a debug, you can change the value of a variable to test how your |
|
29 program handles a particular value or to speed through a loop.</p> |
|
30 |
|
31 <ol> |
|
32 <li>In Variables view, right-click a variable, and select <b>Change Value</b>.</li> |
|
33 <li>Type a value.</li> |
|
34 </ol> |
|
35 |
|
36 <p>To disable a variable value while debugging:</p> |
|
37 |
|
38 <p>You can disable a variable so that the debugger does not read the variable's |
|
39 value from the target. This is useful if the target is very sensitive or the |
|
40 variable is specified as volatile.</p> |
|
41 |
|
42 <ul> |
|
43 <li>In Variables view, right-click a variable, and select <b>Disable</b>.</li> |
|
44 </ul> |
