I am converting my project from vc6 to VS 2010.When I compile my project i get error as below for may .lib inputs. I have added all these lib in the Linker-> Input-> Additional Dependencies, also provided the path of these .lib files in Link->General->Additional Library directories. Any tip on this will be very helpful.

Thanks
You need to identify where the SetLastExP() function is defined.
Check that the library that implements SetLastExP is linked.
Get the .obj file and check with dumpbin if it implements in the decoration that you expect.
dumpbin /symbols foo.obj | find "External" | find "SetLastExP"
Compare the decoration you see with the decoration you have in the Linker error message.
Probably the function is defined as extern "C" while your header file doesn't reflect this.
Sometimes, if you have different Character sets (Configuration properties -> general) in your subprojects, Visual Studio shows this kind of error:
error LNK2001: unresolved external symbol" with an *.obj

I have been trying to upgrade to wxWidgets 2.9.4 over my old 2.8.12 and have run into problems. I compiled it without errors from the command line but when I try to use them in the program that worked just fine under the previous version I get unresolved externals. I cut it down to just a bare frame and TextCtrl object and it still does this (it's basically identical to one of the sample codes at the moment).
I tried the following commands to build the static libraries:
nmake -f makefile.vc SHARED=0 BUILD=release + nmake -f makefile.vc SHARED=0 BUILD=debug
nmake -f makefile.vc SHARED=0 MONOLITHIC=0 BUILD=release + nmake -f makefile.vc SHARED=0 MONOLITHIC=0 BUILD=debug
nmake -f makefile.vc SHARED=0 BUILD=release UNICODE=0 + nmake -f makefile.vc SHARED=0 BUILD=debug UNICODE=0
nmake -f makefile.vc SHARED=0 BUILD=release UNICODE=0 MONOLITHIC=0 + nmake -f makefile.vc SHARED=0 BUILD=debug UNICODE=0 MONOLITHIC=0
Note that I tried using them with both the recommended unicode and no longer supported non-unicode (changed the project properties in Configuration Properties->General accordingly). Also, I used multi-threaded DLL /MD and /MDd linking as recommended by the wxWidgets manual.
Edit: Tried using \MT and \MTd as well, same effect.
From all of the above I get the same linker errors listed below when compiling my application. Please advise me what to do because I have ran out of ideas...
Additionally, as a final resort I built the whole thing using the converted MSVS project from the ../build/msw folder but it gave me the same results.

All errors coming from libpng are due to not linking with wxzlib[d].lib, simply add it to the list of libraries in your project. Or use the recommended way to build wxWidgets projects with MSVC and use auto-linking by prepending -I$(WXWIN)/include/msvc to your compiler header files search path.
The rest of the errors (which you only get in debug build which is suspicious on its own) are due to a mismatch between ANSI and Unicode builds. I don't know which version do you use finally as you seem to have built all of them at one moment or the other but if you use the default build, then you need to have _UNICODE and/or UNICODE defined in your project options.
Finally, to avoid such build mismatches in the future, either do nmake -f makefile.vc clean or use different build directories by using unique COMPILER_PREFIX for each build in the future. This is really not rocket science, you just need to avoid confusing yourself by doing too many things at once. Good luck!
Go to your project's settings and change General -> Character Set property accordingly. If you compiled the wx libs with UNICODE=0 (however recommended value is 1) then you need to use Multi-Byte Character set. If compiled ith UNICODE=1 then set that property to Unicode
As for runtime libs, if you compiled with SHARED=0 then in your project settings you will need to use C++ -> Code Generation -> Runtime Libraries property with 'Multi-Threaded Debug' and 'Multi-Threaded' for Debug and Release build accordingly.
The easiest way is to build wxWidgets libs from Visual Studio (there is a build/msw folder which contains solution file for VS2010) and in your project set the same properties as wx libs projects have.
I had this problem as well. I solved it by changing the setting in:
C/C++ | Language | Treat WChar_t as built in type
to Yes.
I get the following error while trying to compile a sample implementation of firefox protocol handler. I am using Gecko SDK 3.6, Visual Studio 2010 on Windows Vista. I think the sample is very old and was not build using version 3.6 of the SDK.

I belief the sample was using the complete mozilla implementation to get the header files. Now since we have gecko sdk all the internal linkage will have to be migrated to use frozen linkage because internal linkage is not supported by gecko sdk 3.6.
So in my case i changed nsAString.h to nsStringAPI.h and followed other guidelines
I am trying to use Boost Unit Test Framework by building a stand alone library as detailed here:

1>C:\Users\Rafid\Workspace\MyPhysics\Builds\VC10\Tests\Debug\Tests.exe : fatal error LNK1120: 6 unresolved externals
They seem to be mainly caused by Boost debug library, but I can't see a reason why I should get linking errors putting in mind that Boost debug library only need to be included as header files, rather than linking against as a library!
Any ideas?!
OK, I figured out what the problem is. Apparently, the list of files mentioned in Boost's website misses the following files:
debug.cpp
test_main.cpp
test_tools.cpp
Once I added those files to my project, the test project compiled and run successfully!
UPDATE: Just wanted to mention that I actually built against Boost 1.51, so it could be that the documentation is a bit old, because I can see that in the page, they are linking the files to Boost 1.35!
For compile unit-tests of boots 1.57 on windows,
I use #Rafid answer,
For me it was add this files to projects:
test_tools.cpp
unit_test_main.cpp
framework.cpp
That locate in BOOST_DIR/libs/test/src

It seems to indicate that the asio::detail namespace didn't get included in the boost-system library as it is only those 5 symbols that it seems to have a problem with and it is linking to the boost-system library just fine otherwise. I'm trying to build a 32-bit application on a 64-bit system, but everything I've checked seems to be correctly configured for this.
I know I'm missing something, but I can't seem to figure out what. Does anyone have any suggestions?
With BOOST_ASIO_SEPARATE_COMPILATION defined, in addition to #include "boost/asio/ssl/impl/src.hpp", you must also #include "boost/asio/impl/src.hpp" in one of your cpp files.

Those symbols look like functions from the "cutil" library which is included with the CUDA SDK, so you ought to make sure that Visual Studio is set up to link against cutil.lib.
