I am using a third party library in a project and it spams the Output console with its own messages. I have absolutely no desire to see the messages when I'm debugging my code. Is there any way to tell VS to not display the outside libraries messages and only display mine?
You cannot filter the output debug messages, but in general there is way to tell the libraries not to dump messages to the output debug window (compile time define / runtime call / outer configuration tool like netsh.exe).

I have been using the Metrowerks Codewarrior IDE for many years. It's C/C++ compiler generates what Metrowerks calls 'browser info'. This browser info makes it possible to double click a typename/functioname and automatically the correct file is openend displaying the definition.
Now the mentioned IDE has the possibility to use external toolchains (compiler,linker etc.) by means of plugins. I have succesfully created compiler and linker plugins for both the Microsoft as the GNU toolchains. The only thing I don't know is how the generate the mentioned 'browser info'. Which command line do I have to execute to get the information I need?
Compiler flag /FR generates browser info files: /FR, /Fr (Create .Sbr File), and then you can use bscmake to compile these into a .bsc file.
However I've no idea how you'd consume these .sbr files or .bsc file in your plugin. I guess you'll need to find a DLL or COM interface from Visual Studio to give you something to work with. There are other options e.g. map files if they're easier to consume and have enough information for you.
My project has a vendor.js file that is showing warnings (TS7027 unreachable code detected).
I don't want to fix those warnings since it's vendors code. But I don't want to see those warnings either.
Is there a way to tell Visual Studio (2017) to suppress all messages for this file (e.g. with the CodeAnalysis.SuppressMessage attribute)?
I am not using resharper, just the built-in code analysis tool.
I am using Visual Studio 2010 to debug an application mostly written in C. Normally, I can attach the debugger just fine, but I am running in to some problems when I link in a library written in C++ / CLI.
If I compile the library with the /clr flag (which I will eventually have to do for this as of yet unwritten library) then I lose all ability to debug the entire C application, even the parts that have nothing to do with the library calls. I get the empty circle with the yellow triangle and exclamation mark where a red break point circle ought to be. Hovering over it gives me only a tool tip that says "The breakpoint will not currently be hit. No executable code is associated with this line. Possible causes include: conditional compilation or compiler optimizations."
Then if I link with the exact same library compiled without the /clr flag, I am again able to debug my application.
I understand that visual studio will not likely be able to debug the library written in C++ / CLI, and that is OK. I just want to keep the ability to debug the rest of the application and at least see the results of my calls to the external library.
Another complicating factor is that this project is not being built by visual studio. It is compiled using an external make system that uses cl, so I can customize any commands that need to be issued to the compiler that way.
Does anyone know why I can't currently debug the libraries the way I want to? Any advice for how I can?
You have to select the kind of debugger when you attach. Note the "Attach to" label in the dialog. Press the Select button and tick "Native" to get support for debugging native code. The DLL also needs to be loaded before any of your breakpoints can hit. If you are not sure whether or not that was done then look in the Debug > Windows > Modules debugger window to see loaded DLLs. The breakpoint indicator turns from hollow to solid red as soon as the debugger saw the DLL load and armed the breakpoint.
Debugging C++/CLI is otherwise supported, you can tick both the "Managed" and "Native" checkboxes. And set breakpoints in either kind of code. The only thing not supported is single-stepping from managed to native code and back. A mode-switch is required to activate the correct debugging engine, that requires code to hit a breakpoint.
And consider the Debug options in your native project, you can specify an EXE to start. So that you can simply press F5 to start debugging and skip the attach hassle.
It might also have to do with the Debugger Type!
(but that depends on your specific building configuration about which I do not know enough)
If any of your projects is complied with Common Language Runtime Support (/clr) you should set the Debugger Type in your startup project to "Mixed", since the default setting "Auto" might fail!
Imagine, you have two projects:
1) A non-CLR C++ project, which is your startup project that generates some .exe file.
2) A C++ project, that generates mylibrary.dll, which is compiled with Common Language Runtime Support, because it uses some managed code. The .exe from the first project calls mylibrary.dll.
If you start the first project with Debugger Type set to its default value "Auto", you'll be able to debug into the first project, but not into the second one. The debugger selector does not realize that you will be calling a CLR-library.
So set Project Properties -> Configuration Properties -> Debugging -> Debugger Type to "Mixed"!
I have an NUnit test dll written in C++/CLI, which tests some unmanaged code. Is there a way to print log messages to NUnit's Text Output tab from the unmanaged code? I tried OutputDebugString and cout << "blah", but no cigar.
NUnit version: 2.5.10
I know this might be bad practice, but let me do it just once, ok? :P
There isn't any way to my knowledge to capture this output in the output tab.
However, there is an undocumented option, /console, to the NUnit GUI runner that creates a separate console on which any unmanaged output to standard output is displayed. It may also capture standard error - I wrote it a long time ago and don't remember.
I'm trying to debug a C DLL that I'm using with a Delphi program. I built the DLL with Visual C++, with debug information enabled. I built the Delphi program with Delphi 2009, with debug information enabled. But apparently they use different formats, because when I try to attach the VC++ debugger to my program, it says "binary was not built with debug information" and won't even accept as valid the breakpoints I put in the C code, which was built with debug info in the format VC++ understands.
Does anyone know how I can get this to work?
When you say "won't accept as valid" the debug breakpoints in the C code what do you mean exactly? Does it not enable them? If so has the DLL been loaded yet when you set the breakpoints? I find it can simplify matters if I wait to set the breakpoints until after I'm sure the DLL in question has been loaded. If this is not what is happening, please elaborate on what you mean by "valid" breakpoints.
Other options are to set function breakpoints, or the compile the DLL with strategically placed DebugBreak() calls.
Are you sure it's the right DLL that's being loaded (i.e. the debug version)?. Again, even the right DLL is being loaded I'm not sure the error is necessarily applying to the DLL and not just the main executable. Or it could be having problems loading the symbol database as suggested by jdigital, assuming you extract them out for debug builds of your DLL. Even with no debugging symbols, debugging should still be feasible, especially since it's a DLL, you can work from the exported symbols.
This isn't a COM component is it? If it is, I'd double check that the debug version was the one registered before you start up your process.
Again I'd still be interested in hearing exactly what happens when you try to set a break point. If you go to the breakpoints window in VS it should clarify why the breakpoint couldn't be set, if that's what is happening.
Hmm. I don't have much experience with /Z7, do you still have the .obj file for the DLL? The docs seem to imply that's necessary for debugging. Alternatively I'd try building with /Zi instead and getting a .pdb for that sucker.
Not sure about Visual C++ (don't have it installed at all anymore), but maybe this will help...
If you were writing a DLL in Delphi and using it from C++, and you wanted to debug the DLL, you'd open the source for the DLL in Delphi and set a breakpoint. You'd then use Run|Parameters and set the C++ application as the host executable and hit run in the Delphi IDE. The IDE would then launch the C++ application and run it as usual until the breakpoint in the DLL was hit, and then would break as you'd expect.
Is something similar available in VC++? (You didn't say which version of VC++, or which version of Visual Studio or the earlier IDE you were using.)
If not, the only alternative I could think of is to do a quick VC++ app that uses the DLL and debug via that instead.
Debug formats are not standardised - basically you can't use Delphi to debug MS compiled code or vice versa.
You can debug Delphi DLLs in Delphi and you can use those DLLs with other apps not compiled with Delphi, provided you mark the Delphi functions for export. What you can't do is debug those DLLs symbolically in a 3rd party debugger, which would have to understand Object Pascal name mangling at the very least.
Have you pointed the debugger at the symbols for your DLL? If there's any doubt, try running with Filemon to see if the debugger is failing when it tries to load the symbols.
Insure that is opening the DLL in the Debug Folder, not another one in some other folder.
Ten years later and this is happening to me, while debugging a custom DLL used in Team Developer, setting debugging command to start the Team Developer IDE. The objective is to step through the 3rd party code to the point of invocation of an exported function from the DLL.
Starting the debugger launches the IDE without error, but running the TD project within the TD IDE causes an exception in VS on a DLL used by the TD IDE.
How do I ignore the exceptions from outside the project? Has anyone been able to get around this since '09?
