After upgrade app from Clarion 9.1 to Clarion 10 and after first build an error acquiring.
Error: Unresolved External SHGetFolderPathA in EFOCUS.obj. I include efocus.clw in solution. Efocus.clw and efocus.inc are in C10 folder.
Help me please
I dont use the enhanced focus feature, but a couple of things might help:
SHGetFolderPathA is deprecated but should still be around since its in Shell32.dll. Its possible SV eliminated it from their lib in lieu of the replacement call (see https://msdn.microsoft.com/en-us/library/windows/desktop/bb762181(v=vs.85).aspx ), but I doubt it. Even so, you could make your own lib using the DLL and Libmaker.exe (which is shipped in \c10\bin).
It may be simpler than this. Delete the clw and obj from your app folder (or sub-folder where the .RED directs them) and recompile.

The title says it all. But, are there too many files to be replaced and is there a risk? What I mean is, there are files like d3d11.dll. Could I replace the files with with something like d3d12.dll or something like that?
When code is compiled it uses 'headers' and usually links to 'libraries' which refer to functions inside the dll. When the game loads it maps the DLL into the address space of the executable so that the program can use features in the DLL.
So if the Game does D3D11_DrawTriangles, it will end up calling that feature in d3d11.dll. Dropping in the DX12 DLL won't work because the expected function is no longer there (and besides, the executable would still be looking for the 11 DLL - it wouldn't even load).
Upgrading from DX11 to DX12 is a major undertaking; the graphics APIs are very different.
Put another way: It's like someone dropped a Fiat engine into your Volvo. Would it work? How much effort would it be to rewire all the pipes and electronics to make it work?
dllmain.cpp(16): warning C4447: 'main' signature found without threading mode
l. Consider using 'int main(Platform::Array<Platform::String^>^ args)'.
Above is a warning I got from building a Windows Store App DLL project. I didn't change anything in that default dllmain.cpp file except for including my own version of pch.
The documentation for this warning (along with many VS2012 errors/warnings) is nowhere to be found on MSDN and here is the only relevant link I can find:
http://social.msdn.microsoft.com/Forums/en-US/vssetup/thread/6daa9587-fe54-4e84-a8b9-0e5c52c2f6e8/
and the op there didn't get an answer.
If anyone knows what it means and how to fix it, it would be great!
As far as I can tell, you can safely ignore the warning. The compiler cribs when it sees a Win32-style DllMain being compiled using the /ZW flag (Consume Windows Runtime Extensions). However, the function gets called as you'd normally expect.
Alternatively, you can work around the warning by compiling dllmain.cpp without /ZW. You might need to adjust the PCH settings for this to properly work. This is the path taken by the DLL (Windows Store apps) C++/CX project template in Visual Studio.
Incidentally, the reason you do not get the warning when you're trying to build a Windows Runtime Component project (which builds everything using /ZW) is that a Windows Runtime Component doesn't declare a DllMain. This is not to say that it can't; it just picks up the dummy DllMain that the CRT defines (which basically turns off per-thread initialization and reports success).
I am pretty experienced writing my own code, but not in C++. I am used to adding .NET assembly references, and I want to get into using C++.
I downloaded a VC++ 6 project presenting a graph algorithm, opened it in Visual Studio 2010 Ultimate and downloaded the required libraries (LEDA .NET assemblies) however, they came with both DLLs and LIB so I thought I would have no problems with the .NET and C++ connection. Also, the LEDA project comes with C++ style .header files, and static libraries, yet frustration persists.
I put my LEDA header files in a directory visible to the project, since I can "Go to definition" of all the custom LEDA data types and see where they are defined in the LEDA include files.
But, I can not compile/link these data types in. The VS finds their very existence repulsive, and refuses to acknowledge they could possibly be found in leda.lib.
Steps I have already taken:
Added additional /LIBPATH path under Properties ->Linker->General
Added explicit lib references under Properties->Linker->Input
Added all the paths containing LEDA header files and libraries to every path location I can find, like include path, reference path, library path.
Copied the DLLs and LIBs to the release folder as well as the base folder of the project.
Added a #pragma comment( lib, "leda" )
Still no joy.
It's quite bad since none of the custom typedefs are recognised the errors balloon to 646 errors.
If anyone is kind enough to offer assistance, thank you.
I can't guarantee this will work but try the following steps (therefore using it's default predefined paths instead of setting your own ones) :
1) Copy *.dll into Windows/System32 or / and (there is some confusion about x64 and x32 default checking in my head :)) Windows/SysWOW64.
2) Copy *.h files into x:\PathToVC2010\include\
3) Copy *.lib files into x:\PathToVC2010\lib\
I am trying to build an old version of an application which consists of VC++ projects that were written in Visual Studio 2003.
My OS is Windows 7 Enterprise (64-bit).
When I try and build the solution I get the following errors:
error C4772: #import referenced a type from a missing type library; '__missing_type__' used as a placeholder
fatal error C1084: Cannot read type library file: 'Smegui.tlb': Error loading type library/DLL.
They both complain about the following import statement:
#import "Smegui.tlb" no_implementation
This is not a case of the file path being incorrect as renaming the Smegui.tlb file causes the compiler to throw another error saying it cannot find the library.
Smegui is from another application that this one depends on. I thought perhaps I was missing a dll but there is no such thing as Smegui.dll.
All I know about .tlb files is that they are a type library and you can create them from an assembly using tlbexp.exe or regasm.exe (the later also registers the assembly with COM)
There is also an Apache Ant build script which uses a custom task to invoke devenv.com to build the projects. This is the same script that the build server originally used to build the application. It gives me the same errors when I try and run it.
The strangest thing about this is that I knew it ought to work seeing as it is all freshly checked out from subversion. I tried many different combinations of admin vs user elevation, VS vs Ant build, cleaning, release.
I have got it to build successfully about 5 times but the build seems to be non-deterministic.
If anyone can shed some light on how this tlb stuff even works or what this error might mean I would greatly appreciate it.
I found a far more reliable solution: open the tlb with oleview.exe and then close it.
Not sure what this actually does but it works every time.
I think oleview is actually one of the samples included with Visual Studio but I haven't had the time to debug it and see what it is doing.
I ran into this error because one type library was trying to load a dependent type library, which it could not find. Even though the dependent type library was in the same directory, and even though that directory was in the searchable path, the compiler would error loading the first type library, but not mention the dependent type library in the error.
To find the pseudo-missing type library, I ran Process Monitor (procman64.exe) during the compile. This showed that after the reported type library had successfully loaded, a dependent type library could not be found. It even showed all of the places that it was looking for the dependent type library, none of which were where it should have been looking (e.g.: ).
The fix was to add a <PreBuildEvent> to the project to copy the dependent .tlb file to one of the directories that was actually being searched.
<PreBuildEvent>
<Command>copy /Y ..\Lib\Interop\CWSpeechRecLib.tlb .\</Command>
</PreBuildEvent>

smegui.tlb is referencing some other tlb that the compiler can't find. If you have the .idl for smegui you might be able to figure out what the other is. I suspect the missing tlb is something that original build machine had registered but that your machine doesn't have registered.
A type library is a binary description of a set of interfaces, coclasses and enums. They're usually generated for COM components, in the case of tlbexp and regasm the tlb is created from the assembly metadata. For native COM components they are usually generated from an idl (Interface Description Language) file by the midl tool.
Edit:
I just noticed you're on x64 Windows. Are you building the project with a new version of Visual Studio? If so, are you targeting x86 or x64? If the latter, it may simply be a 32bit component that the compiler can't find (or less likely, a x64 component the x86 compiler can't find if you are targeting x86), for WOW64 the registry is virtualized for x86 vs. x64 applications.
Well I finally found out why I managed to get it to build sometimes and not others... sort of.
So long as I ran the build script with elevated administrator permissions and let that get as far as it could until that error occurred, then run the build script again as a protected administrator succeeded. Those steps must be done in that exact order with no other steps in between. If I try build in Visual Studio it does not work (although I did get it to succeed once). Probably some kind of virtualisation issue although it still doesn't quite make sense.
Well I don't need help on this any more and I know it's probably impossible to fully answer this question without knowing exactly what the build is doing. However if anyone does have any more thoughts I would happily receive them.
Cheers,

I'm trying to link my XPCOM extension against the 1.9.3a3pre SDK and I get the following:
error LNK2001: unresolved external symbol _moz_xmalloc
So, what lib do I need to link to? The documentation doesn't say.
This is on Windows right now, but I'll need it to build on Mac and Linux (32bit/64bit) as well.
Edit: Now with bounty.
Edit: Update: Turns out FF3.7 was cancelled. So I don't have to worry about this until FF4.
I have same error, and linking to mozalloc helps for that.
define 'XPCOM_GLUE' in C++ Preprocessor Definition property. It will fix the linking error.
Try defining MOZ_NO_MOZALLOC when compiling your extension, you will then get a DLL that uses your CRT's allocators. (Don't forget to use the NS_* allocators for XPCOM-compatible memory.)
Add MOZ_NO_MOZALLOC in C++->Preprocessor->Definition property.
Use xpcomglue_s_nomozalloc.lib instead of xpcomglue_s.lib in Linker->Input->Additional Dependencies
It will be OK!
reminder note: another option that can cause this even though everything else seems to be configured correctly in the project, is pointing at the wrong libs folder - such as 32 bit version for a 64 bit build.
edit v40 mozalloc.lib has changed name to mozglue.lib and has some additional methods.
edit v41 mozglue.lib has changed name to mozcrt.lib
