Is there a possibility to re-run already executed line in matlab like Visual Studio. In Visual Studio, one can set the next line for execution in debug mode. Does matlab have this feature?
Not perfectly sure whether this is what you are looking for, but you can highlight some code with your mouse and then press F9 (note that this is the Windows shortcut, not sure whether linux or OSX are the same). The highlighted code will then be executed, this feature is called "evaluate selection".
I am not aware that you can interfere with the order of code execution in MATLAB in another way (except typing stuff in the command line while debugging).
Warning:
As suggested by Dan in the comment, note must be taken that this will alter the workspace and naturally this can interfere with the execution of your program in undesireable and at first unintuitive ways. You should keep this in the back of your head at all times while altering the workspace during program execution.

I have been given a project that is the biggest pile of spaghetti I have ever seen, with 0 unit tests or any obvious naming conventions.
I find it hard to believe there is still no way while running in Debug to have Visual Studio automatically break on the next executing line of solution code.
In this case, I know the code is hitting a specific 5000 line of code file - but there isn't even an easy way to just write a breakpoint to every single line!
Is there any logical reason why in 2017 (or even 2010) this functionality doesn't exist?
Or perhaps it does and I haven't found out how!

Please Put a break point in your code -> debug, then Right click on the text editor in VS, you will see below:
You can use the "Break all" button in the visual studio (Ctrl+Alt+Break is the default shortcut).
You might need to switch between the running threads in order to see highlighted instruction within your code.
Then you can just continue debugging, as usual.
If you do not see any of those two controls, go to View->Toolbars and check both "Debug" and "Debug Location".
I've been working on a C# project and I don't know the program flow. I want to know all the executing codes in a particular flow. I can press the pause button to check current executing code, but to check entire flow, I need to keep on pressing F11 or next line, which is cumbersome. BTW, I got it from here
Find out what line of code my app is currently running in Visual Studio's debug mode
I would like to know is there any way in visual studio to check currently executing code without pausing or placing break points?
I often use the VS debugging breakpoint or debug menu options like "Step Into/Out" or use the pausing button.
But if you don't want to use them, the Runtime Flow tool is a workaround I know which can help you see code that is executed:

A feature request for VS IDE:
https://visualstudio.uservoice.com/forums/121579-visual-studio-ide/suggestions/17332198-is-there-any-way-to-check-currently-executing-code
In VS2017, debug has a new feature called "Run execution to here", I know that it doesn't really meet your requirement, but it is a better workaround if you don't want to step Into debugging one step by one step. Move your mouse to the icon and click the button, now your code will run and stop on that line the next time it is hit in your code path.
If you want this ability at debug time then consider IntelliTrace
ReSharper has a Call Tracking feature that can display incoming and outgoing calls sequenced in an interactive, graphical tree view.
See if this helps.
The issue here is that there is code running but you don't know where and you want to see what is going on. A good example is the code is stuck in a loop somewhere but you don't know where.
To break-into the running code:
Option 1: Select the 'Debug' menu item, and then select the 'Break All' menu item.
Option 2: Press keys Ctrl+Alt+Break.
This will break into the code where it is executing and you will step into debugging just as if you hit a breakpoint.
Happy debugging!
I am using the Visual Micro extension for Microsoft Visual Studio, which allows me to debug my Arduino project (in opposed to the Sketch IDE).
For some strange reason, when no breakpoints are present, it automatically adds a breakpoint at the beginning of the loop function.
When running via the debugger, I can simply remove it and continue running.
However, I cannot do the same when running without a debugger (i.e., upon power-up), since breakpoints seem to be "embedded" into the code as additional code segments (though I'm not really sure how explain the fact that the debugger allows me to remove a breakpoint).
Here is an illustration of the problem:
Now, I've been able to work-around it by adding a piece of "dead code" with a breakpoint:
if (0)
{
// insert a breakpoint here
}
But this feels kinda "clumsy".
I suppose that if there is a solution to this problem, then it lies somewhere in here:
But I have not able to find it, so any help will be highly appreciated.
Found the answer!
It turns out that all I needed was to hover on top of the breakpoint and read the tooltip carefully:
As you can read on the bottom line of this tooltip, in order to switch off that automatically-generated breakpoint, we only need to disable the Visual Micro's Tutorial Mode:
And voilà - we're all done!
How can I find out which line will be executed after performing any action?
If I know what will be executed I can put break point there. But what if I am not sure where to set breakpoint or just I need to go to the executing line faster (without setting breakpoints).
"Break All" is not what I look for. It is pausing debugging, so I cannot perform any action (just after which I want Visual Studio sets breakpoint automatically)
In other words, for example I want to start debugging each line after clicking a button, without putting breakpoints. Is it possibile?
For a .NET application you can use my Runtime Flow tool (30-day trial) to see code that is executed after some action.
Set a breakpoint at the line you want to stop after. Then once the breakpoint is hit Step Into or press F11 in Visual Studio. This takes you to the very next line of code that executes, no matter where it is in the project.
I'm new to VS. I came from Eclipse. Could anyone let me know how I can display the outputs as they were in Eclipse?
Anytime I "Run" (Build&Run) the code, the command line show up about a second and close up.
As I don't want to add any code like cin >> xxx to keep the command line window from closing, could anyone let me know how I can get the output within the Development window? Thanks!
There is no option in Visual Studio that says 'Build and Run', its either from 'Build' or 'Run' category. You build, and then run. When you run, it may build the solution, if necessary.
You can run solution either with deubugging (F5) or without debugging (Ctrl+F5). When you run with debugging, you may not see output. Run without debugging Ctrl+F5, and output window will wait for user input.
You may use (for testing purposes), getch, getchar or other function.
