- Mar 20, 2018 Watch Expression. Instead of writing again and again a variable name or an expression you are going to check a lot during a debug session, add it to the Watch Expression list. XHR/Fetch debugging. From the debugger open the XHR/Fetch Breakpoints panel. You can set it to break any time an XHR / Fetch call is sent, or just on specific ones.
- Oct 11, 2018 Open a Watch window by selecting Debug Windows Watch Watch 1, or pressing Ctrl+Alt+W 1. You can open additional Watch windows by selecting windows 2, 3, or 4. In the Watch window, select an empty row, and type variable a. Do the same for b and c. Continue debugging by selecting Debug Step Into or pressing F11 as needed to advance.
Cannot watch the values of variables in debug mode windows 10.0 visual studio 2017 version 15.4 debugger jingting gui reported Oct 11, 2017 at 06:23 AM. Jul 07, 2017 dev c debug, dev c debug not working, dev c debug watch variable, dev c debugger, dev c debugger not working. Aug 25, 2017 How to debug program in Dev C. Examine variables. When the code has stopped at a breakpoint, you can examine its state in the variables pane of the debugger. Variables are grouped by scope: in Function scope you'll see the built-in arguments and this variables as well as local variables defined by the function like user and greeting.Similarly, in Global scope you'll see global variables you've defined, like greetme, as.
Pseudovariables are terms used to display certain information in a variable window or the QuickWatch dialog box. You can enter a pseudovariable the same way you would enter a normal variable. Pseudovariables are not variables, however, and do not correspond to variable names in your program.
Example
Suppose you are writing a native code application and want to see the number of handles allocated in your application. In the Watch window, you can enter the following pseudovariable in the Name column, then press Return to evaluate it:
/camel-crusher-vst-download-free.html. $handles
In native code, you can use the pseudovariables shown in the following table:
| Pseudovariable | Function |
|---|---|
$err | Displays the last error value set with the function SetLastError. The value that is displayed represents what would be returned by the GetLastError function. Use $err,hr to see the decoded form of this value. For example, if the last error was 3, the $err,hr would display ERROR_PATH_NOT_FOUND : The system cannot find the path specified. |
$handles | Displays the number of handles allocated in your application. |
$vframe | Displays the address of the current stack frame. |
$tid | Displays the thread ID for the current thread. |
$env | Displays the environment block in the string viewer. |
$cmdline | Displays the command line string that launched the program. |
$pid | Displays the process ID. |
$registernameor @registername | Displays the contents of the register registername. Normally, you can display register contents just by entering the register name. The only time you need to use this syntax is when the register name overloads a variable name. If the register name is the same as a variable name in the current scope, the debugger interprets the name as a variable name. That's when $registername or @registername comes in handy. |
$clk | Displays the time in clock cycles. |
$user | Displays a structure with account information for the account running the application. For security reasons, the password information is not displayed. |
$exceptionstack | Displays the stack trace of the current Windows Runtime exception. $ exceptionstack works only in UWP apps. $ exceptionstack is not supported for C++ and SEH exceptions |
$returnvalue | Displays the return value of a method. |

In C# you can use the pseudovariables shown in the following table:
| Pseudovariable | Function |
|---|---|
$exception | Displays information on the last exception. If no exception has occurred, evaluating $exception displays an error message.When the Exception Assistant is disabled, $exception is automatically added to the Locals window when an exception occurs. |
$user | Displays a structure with account information for the account running the application. For security reasons, the password information is not displayed. |
$returnvalue | Displays the return value of a .NET method. |
Precision auto tune culpeper va. In Visual Basic, you can use the pseudovariables shown in the following table:
| Pseudovariable | Function |
|---|---|
$exception | Displays information on the last exception. If no exception has occurred, evaluating $exception displays an error message. |
$delete or $$delete | Deletes an implicit variable that was created in the Immediate window. The syntax is $delete,variable or$delete,variable. |
$objectids or $listobjectids | Displays all active Object IDs as children of the specified expression. The syntax is $objectid,expression or$listobjectids,expression. |
$N# | Displays object with Object ID equal to N. |
$dynamic | Displays the special Dynamic View node for an object that implements the IDynamicMetaObjectProvider. Interface. The syntax is $dynamic,object. This feature applies only to code that uses .NET Framework version 4 or later. |
