You use a debugger to help you find bugs. A debugging tool can find bugs for you only if it knows the intent of your code. A tool can only know the intent of your code if you, the developer, express that intent. Writing unit tests is how you do that.
What is running an app in debug mode?
Running an app within a debugger, also called debugging mode, means that the debugger actively monitors everything that’s happening as the program runs. It also allows you to pause the app at any point to examine its state, and to then step through your code line by line to watch every detail as it happens.
What is a breakpoint in Visual Studio?
Breakpoints are the most basic and essential feature of reliable debugging. A breakpoint indicates where Visual Studio should pause your running code so you can take a look at the values of variables, or the behavior of memory, or the sequence in which code runs.
How to identify where a problem occurs in a code?
If it is difficult to identify the region of code where the problem occurs, set a breakpoint in code that runs before the problem occurs, and then use step commands until you see the problem manifest. You can also use tracepoints to log messages to the Output window. By looking at logged messages (and noticing which messages were not yet logged!), you can often isolate the region of code with the problem. You may have to repeat this process several times to narrow it down.
Why do you need to clarify before debugging?
It helps to clarify the problem that you ran into before you try to fix it.

What is grammatical error in Visual Basic?
These are grammatical errors in the formulation of statements and are picked up by the interpreter while you are typing in the code (providing the syntax checking option - under environment options - is set to yes).

Visual Basic has signalled this error at design time by placing the cursor at the point of omission and displaying a pop up error message.

Can you enter statements into the debug window?

What is debugging to start with?
What do I mean by debugging to start with? Programming is about fixing stuff that doesn’t work, it’s a constant fight to get everything working the way we see it in our planning.

There will be bugs in your program, many of them will be caught by the compiler meaning that you won’t be able to click on Start without Visual Studio telling you that the code cannot be run because you have Syntax error (s). These errors are the easiest to find and fix, thanks to Visual Studio!

Clarify The Problem by Asking Yourself The Right Questions
Examine Your Assumptions
- Before you investigate a bug or an error, think of the assumptions that made you expect a certain result. Hidden or unknown assumptions can get in the way of identifying a problem even when you are looking right at the cause of the problem in a debugger. You may have a long list of possible assumptions! Here are a few questions to ask yourself to challenge your assumptions. …

- When you normally run an app, you see errors and incorrect results only after the code has run. A program might also terminate unexpectedly without telling you why. Running an app within a debugger, also called debugging mode, means that the debugger actively monitors everything that’s happening as the program runs. It also allows you to pause the app at any point to examin…

Inspect variables and check whether they co...
