I was trying to troubleshoot why my default settings. Settings values weren't updating. Visual Studio showed me a recommended fix of refactoring "MySettings" to "Settings" and now every reference to My.Settings is broken and the word settings has turned green (used to be white).
I tried just hitting the undo button, and then closing without saving. But it didn't fix anything. Makes me think it isn't a project issue but a VS2016 issue.
My.Settings.ActiveDrive = My.Settings.Default.ActiveDrive
My.Settings.Save()
This is the code I was altering. I was trying to error proof my code and reset the value to the default to simulate a new user with no saved settings yet. Then I switched Settings to MySettings to see if that'd do anything and VS asked if I wanted to refactor MySettings to just Settings. I said yes... And now the code is broken.
I just want Settings to go back to normal. The way it worked before I hit "refactor MySettings".
I was actually able to figure it out.
For anyone out there that runs into this issue in the future (Since I found 0 results on google about this), you simply go to your solution explorer in the top right, click the drop down icon next to Settings.settings, double click on Settings.Designer.vb, ctrl+f and search for "settings" and rename any class designated "Settings" result back to "MySettings". Don't rename the other "Settings" appearances otherwise it'll break again.
Then your code will go back to having a read-only "settings" option and a class option called "MySettings".
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'm sure there is a simple option for this but I have as yet been unable to find it. Every time I close and reopen Aptana Studio 3 it collapses all the folders in the project explorer and I have to reopen them all, is there a way to get it to leave them open and save the project explorer's state when I close the program?
Thanks.
I cannot find any way to keep the state of the Project Explorer. However, using the App Explorer, the state of your open folder will be preserved. You can also try the "Navigator" which looks just like the Project Explorer, but appears to keep state. I will add the proviso to that: It kept state when I restarted aptana, but it also developed a GUI glitch where it appears to be scrolled to the right so I only see the right half of all of my file names and I cannot fix it, so this may not be a good option if you get the same glitch.
There is also a method which does not do quite what you ask, but may be a good fix for you anyway. If you click "Link with Editor" picture (two yellow arrows) in the Project Editor, it will automatically expand your project hierarchy to match whichever open file you have active. Since your files stay open when you close Aptana, this would keep the Project Explorer expanded to whatever you are looking at even on restart. See this question
You can also set up working sets for various parts of your code that are buried in the hierarchy and use the Project Explorer to show those working sets instead of you projects. This does not save state, but it does give you easy access to common parts of your code that may be deeply buried.
Hope one of these helps you.
My question is on how custom controls should be updated.
I downloaded this owner drawn custom control, which I built, then copied the DLL to the Debug folder of the project and loaded it into the toolbox from there.
I decided to use this button on another project. I was mildly surprised to see the control was still in the toolbox but it seemed to work just fine. I decided to change this custom button's behavior. The button in the toolbox referenced the old version number. So I deleted it and loaded the newly rebuilt DLL.
Now come the problems. The first application--the one where the DLL was added to the toolbox from--still runs okay, but the second application is throwing errors, saying, Type 'CButtonLib.CButton' is not defined. When I add the button to a form, it appears okay. I can change its properties and it shows up in the code windows and in the object browser. But as soon as I try to run it and it throws the errors, it no longer appears in the object browser. References in the code window lose their intellisense.
Things I've tried include:
Copying the DLL to the project's debug and release folders and loading them into the toolbox from there.
Removing it from the toolbox altogether and just adding a reference then copying and pasting a button directly from the first project.
Copying in a form with a CButton on it from the first project.
Scouring the internet for answers
Swearing at the computer.
Nothing seems to work and I've now spent over a day trying to solve this.
I never did get to the bottom of this. In the end I simply had to recreate the entire custom control project using a different name. I suspect the way I added the original project to the toolbox of a different program – as opposed to adding it within the test project it came with – may have had something to do with it, but that's just a guess. Anyway, I can amend and update the new control without problem now, so all's well that ends well. :-)
Failed to create component 'User Control 1'. the error message follows:
'System.NullReferenceException : Object reference not set to an instance of an object.
at System.ComponentModel.ReflectPropertyDescriptor.SetValue(Object Component, Object Value)
.............. etc..........
What should I do to fix this error?
When a User Control won't load into the Visual Studio designer here is what you need to do. These instruction are for vb.net project but c# should be similar. Also, before doing this close all open windows (or at least the source and designer files of the control you are working on.)
One last thing. The FIRST thing you should do is ensure that restarting visual studio doesn't fix the problem. If not you can try the steps that follow. These instructions assume that the errant user controls are in control library project in visual studio. If not you should be able to adjust the directions a bit to get it to work but it is much easier when the control is in its own project.
Do the following:
Make the control library your startup project.
Open the properties for the control library project and click on the debug tab.
Under Start Action click the Start external program option and browse to the Visual Studio executable.
NOTE: what this means is that when you run your solution it will fire up another instance of Visual Studio instead of actually running your solution. The First Instance of Visual Studion (INSTANCE_1) will "host" a second instance of visual studio (INSTANCE_2) when you run it.
Run your solution. INSTANCE_2 will load.
Switch back to INSTANCE_1.
In INSTANCE_1 hit CTRL-ALT-E. This will open up the exceptions dialog box. Check On the THROWN column checkbox next to Common Language Runtime Exceptions.
NOTE: This will ensure that INSTANCE_1 will BREAK at ANY runtime error even if it is hit in a try block.
Switch to INSTANCE_2. In Solution Explorer double-click to open the errant user control.
You should find that INSTANCE_1 OF Visual Studio should have stopped at the line of code that caused the designer to not load the control. Fix the code (which usually means testing for IsNot Nothing before references an object properties...but could mean other things.)
Also, sometimes I find that the control WILL load in INSTANCE_2 instead of breaking on an error in INSTANCE_1. In that case just stop debugging...close INSTANCE_2. Save/Restart INSTANCE_1 and your problem will often have gone away.
The lesson is this. User Control MUST be able to load/reference all objects and their members in order to load it into the designer. So for User Controls that will be placed onto other containers I will usually design events to notify the parent rather than trying to push objects into the child control.
Hope this helps for future reference on this old question.

Instead of the error occurring when you open up a form for editing, it sounds like this is occurring when you are already editing a form and adding new user controls. A CodeProject article that was previously mentioned shows what to do in the case of a form not loading correctly, rather than a specific user control.
Does your user control have any properties that map to custom objects (i.e. not Integer or String)? If so, the Form Designer will attempt to load your properties into the Property Editor. If showing the properties generates an error, the Form Designer will show that to you. I think this is what is happening with your user control.
If you could edit the question and add more information about the nature of the error (more of the error text), it would assist others in helping you better. Alternatively, see if you can find the property that might be causing the error (e.g. whether any property relies on a non-null value being set). You can also take a look at this MSDN article for tips on how to limit the control for just run-time.
Thanks, Seth, for this post! Your solution helped me nail down the error. The only thing I would add to this is that when "INSTANCE_2" loads, you may need to actually load the project file in INSTANCE_2. I needed to because I wasn't dealing with a control library, but instead had custom User Controls defined in the same project that the forms were located in. Once I loaded the project in INSTANCE_2, I opened the erring form and that caused INSTANCE_1 to pop up to the line of offending code in the User Control.
I have found that this error often occurs when control dlls are not building properly. 95% of the time this is remedied by simply restarting Visual Studio.
