So I am currently unable to open a Form and get the following error:
System.ComponenetModel.Design.ExceptionCollection was thrown.
or:
The designer loader did not provide a root component and has not indicated why
Usually the way to solve this is to open another instance of Visual Studio with the same project, attach the debugger to the other Visual Studio and try to open the form.
However, that does not seem to be working. The debugger does not break when the error is hit, and attempting to 'Break All' at any other point does not show me the source code and just the screen saying:
Your app has entered a break state, but there is no code because all threads were executing external code (typically system or framework code).
Attempting to put break points also results in:
The breakpoint will not currently be hit. No symbols have been loaded for this document
Am I missing a setting? Incorrect Setup?
I have been battling this for half a day and thoroughly search the interwebs with no luck thus far. My designer is also fairly complex and lengthy which means trial and error is an absolute last ditch option.
First attempt to resolve:
you may have tried it already. Right click the Solution in solution explorer, click "clean solution", this deletes all the compiled and temporary files associated with a solution.
Do a rebuild of the solution and try to debug again.
Second attept to resolve:
Start debugging, as soon as you've arrived at a breakpoint or used
Debug > Break All, use Debug > Windows > Modules. You'll see a list of all the assemblies that are loaded into the process. Locate the one you want to get debug info for. Right-click it and select Symbol Load Information. You'll get a dialog that lists all the directories where it looked for the .pdb file for the assembly. Verify that list against the actual .pdb location. Make sure it doesn't find an old one.
In normal projects, the assembly and its .pdb file should always have been copied by the IDE into the same folder as your .exe. The bin\Debug folder of your project. Make sure you remove one from the GAC if you've been playing with it.
third attept to resolve:
Disable the "Just My Code" option in the Debug/General settings.
there are might be other causes to your problem, i picked them from here. you may try other solution to try resolve your issues. Fixing "The breakpoint will not currently be hit. No symbols have been loaded for this document."
I just upgraded my Visual Studio from 2012 to 2013 and haven't done anything else yet short of installing all the updates recommended.
For whatever reason, when I go into my solution and press F10 or F11, it runs the entire program as if I had pressed F5... F8 works the way F10 used to, but I don't know why the keys I've always used now don't.
I set up visual studio as a VB environment.
How can I fix this?
Thanks!!!
Additional Info:
Just to add on as much information as I can, if I set a breakpoint in my code, then I can use F10 / F11 to continue stepping through my code once the breakpoint is hit and execution is stopped as would be expected.
EDIT 2013-12-31:
Based upon a comment made by Neolisk, it appears this is simply a change in default behavior in Visual Studio 2013... If anyone knows how to change this back to the way it was in 2012, that would be GREATLY appreciated, but at least I now know it's not an error / installation issue.
If 2013 works the same as previous versions, then do the following:
Navigate to Tools > Import and Export Settings
Choose "Import selected environment settings"
On the next screen, choose to save your current setings if you want to.
When you get to the point where you can import, just select "General Development Settings"
That should set everything back to what you're probably used to. Most people are set up using general settings and either don't realize it or just forget.
EDIT: If your issue is that the program executes when you press F10 or F11 when you are not debugging, then I think you might be out of luck. It's done that to me personally since VS 2008 (I'll frequently miss the F12 key when I'm in a hurry), and, after some searching, I think it actually happens to everyone:
Visual Studio - Prevent F11 from starting the debugger?
My guess is that this is a side-effect of not being able to set contextual hot keys based on whether you are or are not debugging. Since F10 and F11 are tied to debug-execution-related operations, my guess is that Visual Studio realizes that it needs to be debugging to process them, and thus starts the program.
ANOTHER EDIT: Of course, it's also possible that you had the scheme set to something else entirely in VS2012. Check out all of Visual Studio's pre-defined hotkeys by environment here: http://msdn.microsoft.com/en-us/library/da5kh0wa(v=vs.120).aspx
If none of those have the mappings that you're used to for F8, F10, or F11, then it's possible that you or an add-on may have had few custom hotkeys defined.
Worst-case scenario, you can simply redefine your shortcuts manually by key in the keyboard settings: Tools > Options > Environment > Keyboard
It sounds like you are in VB settings and not C#. You should try changing your settings to one or the other and see if those debug options change. On my machine
Tools - Import Export Settings - Reset All Settings - C# (If you want F10/F11) VB if you want F8/Shift-F8. It doesn't matter what your settings are you can still code in both languages, but if you are used to pressing F10 to debug VB.NET code you've been using C# settings this whole time. Nothing new with Visual Studio in this regard. I am using VS2013 Ultimate, have been using Visual Studio since VS2003.
The first image is VB.net, second is C# settings
You can try some of these reset settings:
And different combinations thereof, i.e. ResetToBasic first. If does not help, try ResetToC#, then back to Basic. Then try General, back to Basic. See if you can hack your way through like this.
EDIT: I tried my VS 2012, and compared to VS 2013. What you described is completely normal. VS 2012 used to step in Form_Load and similar on F10 and F11, VS 2013 no longer does it. So it seems like your VS 2013 is working as expected.
Microsoft probably has a reason to not allow to step into a property by default.
Properties are supposed to be mostly get and set and not contain a whole lot of implementation in it. But that may not be the case all the time.
If somebody is trying to step into a property that means this developer is suspecting something in that property that may be causing problems. So by default this behavior needs to be reversed and allow stepping into properties.
For now this is how you can enable stepping into properties.
Go to Tools > Options menu in Visual Studio.
Goto Debugging > General menu item in left pane.
In right view you will see and option Step over properties and operators (Managed only). Uncheck this option and then you are all set.
Enable step into properties in Visual Studio Debugger
If the above didn't work then follow this
In the Options.Keyboard page, please select "Debug.StepOver" from the command listbox, and then put focus to the "Press shortcut keys" textbox and press F10, click Assign button to re-assign shortcut, does it work?
You can also try to run Visual Studio under safe mode, which will prevents all third-party VSPackages from loading when Visual Studio starts; if the issue disappear under safe mode, you may consider checking your installed add-ons or VSPackages.
Second, to log all activity of Visual Studio to a log file for further troubleshooting, please use the /Log switch, and post the log file content here, so we can do more investigation on it.
If this feature works well before, and suddenly behave abnormally, it usually indicate that some files or configurations of Visual Studio installation is corrupted or missed, you can:
Restores Visual Studio default settings by using "Devenv.exe /ResetSettings" command. Please backup your settings before restore to default settings.
Repair/reinstall Visual Studio;
To repair Visual Studio In the Add or Remove Programs dialog box, select Visual Studio then click Change/Remove.
I found I had to run VS as Administrator to debug properly. I also do a clean solution prior to debugging, especially on x64 machines. If you put a manual debug breakpoint in the code and the IDE indicates it can't stop at that point, then it's possible that the debugger is out of sync with the source code.
An idea to test it in a short way:
Create a Hello World console app.
1 Module Module1
2
3 Sub Main()
4 Console.WriteLine("Hello")
5 End Sub
6
7 End Module
Build first.
Put the cursor in line 4 (before each step), commands should start Debug Mode if you are in Design Mode.
F10 (StepOver): Should break on line 3
F11 (StepInto): Should break on line 3
CTRL+F10 (RunToCursor): Should break on line 4
If it is working properly: Maybe the assembly which containing the entry point of your program had modified and wasn't been rebuilded, or there is somthing other problem with the point where the control expected to break.
If it doesn't work as expected on the sample, I think you should ask on MSDN FORUM or make a bug report.
I don't know why they might have intent to change this behavior.
It is working for me in my 2013 Express Edition with C# recently.
I found what I think is an acceptable workaround for the non-functioning F10/F11 Keys. They are probably the most used keys in stepping through code, and it is a real pain to click on debug and select the key from the dropdown.
I got around this shortcoming by adding icons to the toolbar for these operations.
If you are not sure how to do this, On the Debug toolbar click on the down pointing arrow near the right side of the bar. Click on Add or remove buttons.
Select Customize...
Select Add Command
Select Debug
Scroll down to the desired key (Step over / Step into)
You once clicked, you will see the two icons added at the left side
of the toolbar, Unfortunately they are the same Icon, but with a
little use, you should be able to select the right key to click on.
I actually prefer this method to trying to remember which function key
to press.
On many branded laptops, there is an extra button "Fn", Press "Fn" and "Esc" together. Functional keys will be enabled in visual studio.
Kindly press Fn key and Esc (with Lock with Fn label).
Sometimes it gets locked and Media Player buttons get activated.
Sounds stupid to ask but what type of keyboard do you have? I know some keyboards have different modes that allow you to set different profiles for keys based upon the application. I use the feature with my Microsoft Natural keyboard. However I have had problems with the profile still being active when I switch into Visual Studio and then F10, etc doesn't work correctly.
I faced the problem that F10/F11 doesn't work but the breakpoint works.
Once I uninstall the Security Software and unload the relevant drives it works again.
So my advice is that. And I guess it's due to the drives, so if these don't work just try to unload those questionable drives may connected with this question.
Using Logitech MX 3000 Keyboard, I've upgraded to the last setpoint version and these keys work now perfectly. (Driver version 5.90.41)
I recently have encountered a weird issue with my project: as soon as I click debug and it builds the project, it stops debugging. There isn't any error message, or anything else that comes up, including the form itself.
I've tried messing with the settings: no splash screen and I've even changed the startup form to a blank Windows form. What could be causing this problem? Is it Visual Studio or my code?
Probably your program is exiting normally. Set a breakpoint at the first statement to be executed, press F5, then single-step through the program until you get to the last statement executed.
If the first statement is never reached, then one of two things probably happened:
You're mistaken about which statement is executed first, or
The program is terminating during initialization, probably because a class constructor is exiting the program either normally or abnormally.
A few ideas:
Use Debug->Exceptions, and check all the checkboxes so you break when an exception is thrown.
Use Debug->Step into to step into your code.
Then you can use Step Over and Step Into (look at the menu for the keyboard shortcuts)
I found a solution, but not the problem.
How I fixed it:
I just created a template for each form, created a new project, and imported everything into the new project. One thing that I found useful is in the new project is to add an existing item (CTRL + D), and group select (maybe, don't know if you can) and select all the non-code/form/designer/etc. files (like text files or images) and then import them.
I have found a possible solution after I had the same problem.
You probably have more than one project in your solution (The main project, plus an "InstallShield" project",perhaps)
Make sure you have the main project set up as "Startup Project".
In the Solution Explorer, right click on the Main Project and select "Set as Startup Project".
Everything will then run OK.
If you get the error like: "The debug mode is program but there is no program specified....." Go to Solution Explorer then Right Click on main project's name and Click on Set as StartUp project. You can debug your program.
we are using VS 2012 on Windows 7 with 32 bit operating system.
I have enabled "Edit and Continue" feature from Tools -> Options -> Debugging -> Edit and Continue.
still I am not able to edit .cs file in debug mode.
can somebody suggest what am I missing?
I kept the break point in one of mvc controller class.
when it hit the break point, I tried to edit and got the below message:
Changes are not allowed in the following cases:
-When the debugger has been attached to an already running process
-The code being debugged was optimized at build or run time.
-The assembly being debugged is loaded as domain-neutral.
-The assembly being debugged was loaded through reflection.
-When Intellitrace events and call information is enabled.
Just to clarify some bits as it might help others..
1) The answer from [Gupta Anirudha F1beta] is correct
These below applies for Visual Studio 2012, 2013 + MVC 4, I was trying to edit Controller
2) If Edit & Continue is disabled, you cannot make changes in the *.cs code, you will see the message as [mmssaann] highlighted above. To edit your code, you need to stop debugging, edit your code and start debugging again to continue
3) If Edit & Continue is enabled, you can make changes in the *.cs code, BUT you will get a different message after you continue debugging saying Edit or Restart (so the website will be recompiled again). This approach is same as above but it seems a bit faster maybe you save like 1 click which makes in 50 years of coding like thousands of saved clicks :-)
I hope this helped :)
Web application need to be compiled when web-sites is compiled dynamically when executed.
Edit and continue will not work in MVC kind of project. You need to put break point and compile whole project to debug your project.
I made some changes in my code and when I went to debug my program I got a build error. The error prompted my anti-virus software (Avast) to block my program as a "suspicious file".
Visual Studio returned this error:
Error 1 Could not copy the file "obj\Debug\CopyFile.exe" because it was not found.
Here is a run down of the events that occurred before this error began to happen.
Added new menu item to menu strip.
Replaced instances of radio button references in the code with the new menu items.
Ran a debug, program worked fine, until I clicked a button.
Found the remaining instances of radio button references in the code and replaced them.
Ran a debug, program was working fine. Exited debug.
Deleted the old radio buttons from the GUI. (They no longer had any references in the code.)
Tried to debug, received an error, antivirus software blocks program exe file as suspicious.
Error Could not copy the file "obj\Debug\CopyFile.exe" because it was not found.
What did I do to the code to cause this? Did I possibly delete some other area of the code on accident and I do not know? I can't see why my program won't debug.
Why don't you simply tell to your antivirus software to do its business in some other places than your working directory? ( Exclude Paths ) and ignore every action done by Visual Studio executables ?
By the way, this is one of the first things to do to get better performance when working with a complex IDE like VS that can create, move, delete thousands of files when working.
If I remember well, the AVAST has its exclusion list in File System Shield, Expert Settings, Exclusions
