I just tried to open my project in the VS 2017 and suddenly i cant see one of my classes files.
The header and the cpp are missing.
The files are not in the folder and i cant even see them in the Cmake.
When i start the VS and trying to open the project it says:
ex01_files (the name of the folder) could not be opened. Do you want to remove the reference(s) to it from the Recent list(s)?
when i open the project, i get an error at the top that says:
C++ IntelliSense information may be out of date, generate the CMake cache to refresh.
Im new at the VS so im afraid to take action by myself.
If you just removed the header and cpp in VS, you could find these files in the corresponding folder.
If you deleted these files, you could try to find them in the Recycle Bin.
If you deleted these files completely, I suggested that you could use Windows File Recovery to recover lost files.
I am trying to link to a folder that is not inside the project directory. To give an example,
If my project is in C:\project and I have a folder C:\shared, how can I manage to link C:\shared into the project (and being able to edit/view the files in Solution Explorer) without making a copy of the directory and placing it into the project directory.
I need this due to the fact that many projects will use this folder and it would be ideal to have them edit/use the same files rather than copy the folder into each project individually. That way if a bug is fixed in one project, all other projects will now use the fixed files as well.
For more context, this is a C++ project using Visual Studio 2019.
What I've tried/considered.
Additional include directories
Problem: This does not show the files in the Solution Explorer
Dragging/dropping the folder (or copy/pasting) as seen in another StackOverflow thread.
Problem: This just crashes my visual studio completely. The folder is quite large so I assume that's related to why.
Appreciate any insight on how to proceed. It's really unfortunate that this is a pain, I would think that something like this would be common, but all the posts I've seen related to it have either gone unanswered or could not be applied to my situation.
Thanks.
Shared Projects are the key here.. I just found out they existed. After creating one, drop the folder/files in the same directory that has .vcxitems file. Now in the project you want to include the shared folder, right click your solution, Add -> Existing Project and select your .vcxitems file.
I am reorganizing numerous small solutions/projects into one solution in Visual Studio 2017 but I keep getting error messages like:
The folder already contains an item named 'Staging'
Followed by:
Exception of type 'System.Runtime.InteropServices.COMException' was
thrown
The projects are all in individual folders in a folder called Packages with the project folders named like:
Staging.Finance
Staging.HR
Staging.SharePoint
There is no folder called Staging in the Packages folder and there are no files called Staging in the folder for the project I am trying to rename. The project file name is currently Finance-SSIS which I am trying to rename to Staging.Finance.
There is a project called Staging in my solution but this is in a different folder from these projects.
I can rename the project files outside of Visual Studio but want to understand why I'm getting this error.
Upon searching I came across these three solutions:
Try Restarting Visual Studio.
Open Solution Explorer there is an icon that looks like a many
Pages which is the Show All
Files. Once clicked, one is able to see the hidden, to the visual
studio project, the folder that was causing this error. (Look for
the folder in the View section.). After I deleted the unwanted
folder, and Rebuild Project, You should be able to Create the
controller which will create the view automatically
A project can exist in a solution in only one location. To correct this error:
To show hidden Solution Folders, select the solution or a Solution Folder that contains a hidden Solution Folder and then on the Project menu, select Unhide Folders.

I suggest to search in main projects file content about 'Staging' . For example take a look at solution file (with .sln extension) content and search about 'Staging', I hope you will find it there!
I created an empty 'Demo' project in Visual Studio 2008 and added some existing projects to my solution. Included "MyHeader.h" (other project's header) in main.cpp file which is in 'Demo'. Also added header files' path in "Tools/Option/VC++ Directories/Include files" section. But intellisense says: "File MyHeader.h not found in current source file's directory or in build system paths..."
How the problem can be fixed?
Delete the .sdf file that is in your solution directory. It's just the Intellisense database, and Visual Studio will recreate it the next time you open that solution. This db can get corrupted and cause the IDE to not be able to find things, and since the compiler generates this information for itself on the fly, it wouldn't be affected.
If you choose Project and then All Files in the menu, all files should be displayed in the Solution Explorer that are physically in your project map, but not (yet) included in your project. If you right click on the file you want to add in the Solution Explorer, you can include it.
This happened to me just now, after shutting down and restarting the computer. Eventually I realised that the architecture had somehow been changed to ARM from x64.
In Visual Studio 2019 in my case I copied a header file into the project directory, just near the other files. Intellisense could see it, but the build failed. Fair enough, it wasn't actually added to the project. I added it as existing item but this is the point that Visual Studio still didn't account for it.
Solution:
Close the project.
Delete the .vs directory.
Reopen the project.
Now Visual Studio recreates the directory with everything in it and it can now see the included file.
If it is the case that only the IDE indicates that it cannot find included files, but compiling is successful, the issue is simply that IntelliSense is not fully up to date with recent changes. This can happen specifically when including existing projects, in my own experience.
Deleting the .sdf file (= IntelliSense database) that is generated in your solution directory forces Visual Studio to regenerate it, so that it is up to date again. Just doing a "clean" will probably do the same thing, but takes more time since everything will be generated again then.
I know this is an older question, but none of the above answers worked for me. In my case, the issue turned out to be that I had absolute include paths but without drive letters. Compilation was fine, but Visual Studio couldn't find an include file when I right-clicked and tried to open it. Adding the drive letters to my include paths corrected the problem.
I would never recommend hard-coding drive letters in any aspect of your project files; either use relative paths, macros, environment variables, or some mix of the tree for any permanent situation. However, in this case, I'm working in some temporary projects where absolute paths were necessary in the short term. Not being able to right-click to open the files was extremely frustrating, and hopefully this will help others.
Had the same problem. Double check if you added the include files to Debug or Release Version of your project. If you only added it for one of them and compile for the other VS will just play dumb and not find them.
Try adding the header file to your project's files. (right click on project -> add existing file).
In my experience, with VS2010, when include files can't be found at compile time, doing a clean, then build usually fixes the problem. It's not that rare for the editor to be able to open an include file and then the compiler to announce that it can't find that very file, even when it is open on the screen!
If the visual studio says that you miss some file in the current source file folder, there is one solution that i used. Just right click the file you want to add and choose Open Document, if it really doesn't exist, then you should see something like cannot find file in the source file path = "somewhere in your computer", then what you could do is the add your source file into that path first and see if it works.
I had this issue after upgrading to Visual Studio 2019 from 2015. It would compile the project fine but Intellisense and the IDE couldn't find any header files.
The project only had valid configuration for Win32/Debug. Include paths were not setup correctly for other environments. Even though Visual Studio displayed the current environment as Win32/Debug, Intellisense must have been using something else.
Changing the current environment to x64/Release, and then back to Win32/Debug fixed it.
In Visual Studio, click on Project > Rescan Solution as shown below to rebuild the project database.
Here's how I solved this problem.
Go to Project --> Show All Files.
Right click all the files in Solutions Explorer and Click on Include in Project in all the files you want to include.
Done :)
I encountered this issue, but the solutions provided didn't directly help me, so I'm sharing how I got myself into a similar situation and temporarily resolved it.
I created a new project within an existing solution and copy & pasted the Header and CPP file from another project within that solution that I needed to include in my new project through the IDE. Intellisense displayed an error suggesting it could not resolve the reference to the header file and compiling the code failed with the same error too.
After reading the posts here, I checked the project folder with Windows File Explorer and only the main.cpp file was found. For some reason, my copy and paste of the header file and CPP file were just a reference? (I assume) and did not physically copy the file into the new project file.
I deleted the files from the Project view within Visual Studio and I used File Explorer to copy the files that I needed to the project folder/directory. I then referenced the other solutions posted here to "include files in project" by showing all files and this resolved the problem.
It boiled down to the files not being physically in the Project folder/directory even though they were shown correctly within the IDE.
Please Note I understand duplicating code is not best practice and my situation is purely a learning/hobby project. It's probably in my best interest and anyone else who ended up in a similar situation to use the IDE/project/Solution setup correctly when reusing code from other projects - I'm still learning and I'll figure this out one day!
If some soul has scrolled down to this bottom, what worked for me was disabling the Disable Database option i.e. set it to False under Tools|Options|Text Editor|C/C++|Advanced. For some reason, it was set to True for me.
As per docs, if it's set to True
All use of the code browsing database (SDF), all other
Browsing/Navigation options, and all IntelliSense features except for
#include Auto Complete are disabled.
None of the solutions worked for me. Here is what was the issue for me:
(Note discrepancy in build configuration and VC++ Directories (x86 vs x64)
To fix, just changed the build configuration to 'x86':
I have some header and cpp files that are shared between 2 projects, so I have put them in a folder named Common:
C:\Workspace\Common\utils.h
C:\Workspace\Common\utils.cpp
C:\Worspace\Project1\Project1.sln
C:\Worspace\Project2\Project2.sln
The 2 files utils.h and utils.cpp are added to both projects, and they're added to SourceSafe as well. However, "File->Source Control->Check Out" from the menu is disabled for those 2 files, even though they're added to the project.
Is this because they're outside the solution's folder, and how do I fix it? Right now I have to go and manually check out those files whenever I want to edit them.
As you mentioned, the File -> Checkout is disabled because those files are not part of the solution. The only way to check them out from Source Control Explorer is to add them to the Solution. One way to handle this is to add a new 'Solution Folder' and add your Common Folder inside that folder. Then you should be able to do a Get Latest/Checkout from Solution Explorer.
