I have 2 projects in a VS2010 solution. Project A generates an exe, Project B generates a DLL. The Project B DLL is used both by Project A in the solution, as well as a 3rd party program. In release mode, Project A works normally. But when I run Project A in debug mode, it tells me it is trying (and not succeeding) in attaching to the 3rd party program...which it has nothing to do with.
I've scoured the config files for Project A and can't see anywhere where this 3rd party program is referenced. Any ideas?
Edit: the message is:
"Unable to attach. Process "...exe" is not running on Dell [my
computer]. Refresh the process list before attempting another
Attach."
If your trying to debug project A, check if it is set as default project and check for the debug commandline or options.

I have some Matlab .m files that use a C function I've created.
When Debugging in Matlab, or Visual-Studio, is there any way to run step by step both C and Matlab codes in a way that both Matlab a C variables remain usable for debug?
This addresses only the MSVS half of your question...
The steps to use step-by-step debugging using Visual Studio are outlined here. This is just an except centering around a .dll that is hosted by a pre-existing application. Matlab qualifies as a host application, whether it is also being run in debug mode, or not.
Start debugging from the calling app
The app that calls a DLL can be:
An app from a Visual Studio project in the same or a different solution from the DLL.
An existing app that is already deployed and running on a test or production computer.
Located on the web and accessed through a URL.
A web app with a web page that embeds the DLL.
To debug a DLL from a calling app, you can:
Open the project for the calling app, and start debugging by selecting Debug > Start Debugging or pressing F5.
or
Attach to an app that is already deployed and running on a test or production computer. Use this method for DLLs on websites or in web
apps. For more information, see How to: Attach to a running process.
Before you start debugging the calling app, set a breakpoint in the
DLL. See Using breakpoints. When the DLL breakpoint is hit, you can
step through the code, observing the action at each line. For more
information, see Navigate code in the debugger.
During debugging, you can use the Modules window to verify the DLLs
and .exe files the app loads. To open the Modules window, while
debugging, select Debug > Windows > Modules. For more information, see
How to: Use the Modules window. Use the Immediate window
You can [also] use the Immediate window to evaluate DLL functions or methods
at design time. The Immediate window plays the role of a calling app.
[and so on....]
So, the problem that I am having is that when I push F5, or click Start, Visual Studio starts debugging, but the application doesn't actually build. If I go to my Task Manager, and look for the process it isn't there. Or, if I alt-tab between the programs I had open. I have had this problem twice now. The last projet I started, I encountered this problem. I spent days looking for answers on my time off but couldn't find anyhting. So i started a new project. And now I'm getting the same thing. If I go to my source tree and go back to a previous build and discard my changes, it works fine. But the problem comes back. Its not my coding. I am not getting any build errors. And I don't have any break points. So i can't hit continue. PLease alos note, that between it working, and not working I have not changed ANY setings in Visual Studio. I will post what I have tried. If I forget anything, please forgive me. I have days and days of history to go through in my browser.
Restarted Computer and VS
Ran VS in Admin
Always Build is selected in Tools -> Options -> Projects and
Solutions -> Build and Run
Make sure project is set to Debug in Solution Configuration and
Build is checked in Configuration Manager.
Make sure Only BUild startup projects and dependencies on run is
unchecked
Clean Solution
Unchecked Enable the Visual Studio hosting process in Project ->
Properties -> Debug tab
Made sure vshost32.exe was not running in the background while
program was not running in the Task Manager.
Deleted contents of bin and obj files in my project folder file and
reset computer.
Tried running the program from the exe in previously mentioned
bin/obj file. (The last one does start the process in Task Manager. But still doesnt show in the task bar, or alt tab.)
None of these have worked. I am getting very frustrated at this. Maybe I am not looking for the right thing in Google...
I suggest you close all third party tools/processes like the Anti-virus or others, and then re-debug it.
Or
You could run your VS in safemode:
devenv /SafeMode
Some community members found that the symbols loaded is really slow recently, and this issue has been report the Microsoft product team, so please also disable the Microsoft symbols server under TOOLS->Options->Debugging->Symbols. Debug it again.
I have a Visual Studio solution which I'm trying to build using the Incredibuild tool. Two of the projects in the solution work in tandem - the first project (we'll call it "Project A") builds an executable (foo.exe) which can parse a data file in the second ("Project B") to generate some header files.
Obviously there is a dependency on Project A defined in Project B. If I use Incredibuild's Rebuild Project option on Project B, it correctly builds Project A and foo.exe is successfully built. Project B has a custom build tool file which should cause foo.exe to be ran with a command-line argument to the file it's supposed to parse. However, trying to launch foo.exe in this way always returns an error:
CustomBuild:
Running Foo
'path to executable\foo.exe' is not recognized as an internal or
external command, operable program or batch file.
C:\Program Files
(x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.CppCommon.targets(171,5):
error MSB6006: "cmd.exe" exited with code 9009.
Interestingly, if I then use Incredibuild to build only Project B (i.e. using the Build Project option), everything is ok - it correctly picks foo.exe from the location it was built to on the previous, failed, build. This makes me think that the path, at least, must be ok.
Can anyone suggest why the executable cannot be ran as part of the rebuild? Is it a timing issue, e.g. Project B commences before foo.exe is known to the file system??
It all works under Visual Studio's regular (re)build. It's just the Incredibuild rebuild which fails. Note that I'm doing all of this through the Visual Studio IDE, not from a command line.
Edit: this is the freebie version of Incredibuild that I'm using (the one which comes with Visual Studio), so all of the build is on the local machine.
I contacted the Xoreax technical support about this in the end and they told me that this is a "rare but known issue that is related to one of our extra accelerating features".
Their first suggestion was writing an executable which simply sleeps "for a few milliseconds" and having that run as part of the custom build tool post-link. This did indeed solve the immediate problem, but the solution I'm building has numerous similar problems and adding this delay in everywhere quickly became tedious and didn't always work. It felt like a fudge anyhow.
So I asked if this behaviour can be toggled to off, and indeed it can. In Visual Studio the Incredibuild menu has an Agent Settings option, and from the invoked dialog's Visual Studio Builds|Advanced page it's a simple case of unchecking the Enhance throughput using out-of-order tasks spawning option.
Case closed.
There are options how to offload or intercept custom tools during your build process. Try to look onto "c:\program files (x86)\IncrediBuild\Samples"
I just finished coding my c program in visual studio (VS) and what I had done is just drag the compiled .exe file out of the folder to run it on other computers, except on other computers for that to work I guess I need VS since it says the MSVCR110D.dll is missing which is from VS. So how can I run my program on other computers that don't have VS?
You can use IExpress which is used for distributing self-contained installation packages. It is there in every windows machine preinstalled. Using this utility you can make the executable .exe which will be incorporated with dependent dlls. You can see Step by step guide, to see how to use it.
Follow these steps
https://msdn.microsoft.com/en-us/library/3w7axy17.aspx
In your output window it will show you where you can find the exe file, usually something like "ProjectName/Debug/Release/"
If you have added any external libraries you will have to copy any DLL files in that folder with the exe (You can combine them with some applications if needed)
You will also have to make sure that you have the correct version of the .NET Framework on the PC that you are trying to run your program on
I'm a rookie at C in general and VS 2013 also. I am trying to use some C code provided by a vendor in VS 2013 express. It compiles and runs without problem using the command line compiler but I would like to use the IDE.
I started a new project, C++ for console app, and I have pasted the code into the IDE and saved it as xyy.c so that it builds successfully. I thought it would be nice to have it in a GUI, so I duplicated the effort with a Win32 app project. It also builds.
The program's job is to connect to a PCI card that has Plx chip as an interface and program an FPGA. The Win32 program succeeds, even though I can't see any of the info printed by the program. The console program fails and I think it is because it fails to find the driver for the Plx chip. I thought I would get a clue by single stepping through the Win32 program to see which driver was supposed to be found.
However, after the first pass through a while loop, I get a pop up that says "Source Not Found" and "stack.cpp not found". Google wasn't any help to me.
I be grateful for any suggestions.
You might have "Enable .NET Framework source stepping" enabled (see http://msdn.microsoft.com/en-us/library/cc667410.aspx). So when you are at Stack... and trying to step into, it will actually try, but you don't have the sources for that. There is also a new experience for using the .NET framework reference source that was announced recently: http://blogs.msdn.com/b/dotnet/archive/2014/02/24/a-new-look-for-net-reference-source.aspx
I faced the same problem. I advise at the moment of receiving the information "stack.cpp not found" to look at the stack trace and check if there is something like this: "RTC".
If there is, you need to change the flag along the path (for example, set the Default or a more convenient configuration for you):
Project Properties -> C/C++ -> Code Generation -> Basic Runtime Checks
