RTFx Powertoy Linker Error, and a solution

  • Article

Posted by Dave Edson

If you get this error when building a plugin for the Microsoft Smart Devices Remote Tools Framework (RTFx):

Error 1 error LNK2019: unresolved external symbol "__declspec(dllimport) public: static long __cdecl CDeviceRemoteTool::StartCommandHandler(wchar_t *,enum CDeviceRemoteTool::COMMANDHANDLER_TYPE,long (__cdecl*)(unsigned long,class CCommandPacket const *,class CCommandPacket *))" (__imp_?StartCommandHandler@CDeviceRemoteTool@@SAJPA_WW4COMMANDHANDLER_TYPE@1@P6AJKPBVCCommandPacket@@PAV3@@Z@Z) referenced in function WinMain DeviceSide.obj  

 

Then it means that a compiler switch needs to be changed. For the device-side native projects, open the properties for the device side project. Then, go to the C/C++ node, and choose "Language". Change the "Treat wchar_t as a built-in Type" to "No (/Zc:wchar_t-)".

 

Hope this helps,

    What happened to other blogs in this site. A lot of them have closed for "comment". I have a question regarding file system. If you could find someone give us a clue, I definitely will appreciate it

    The question is: Is the following a Microsoft bug on Windows CE?

    You can successfully call CreateFile with
    CreateFile(L"eicar.txt",.....)
    CreateFile(L"Windowseicar.txt"....
    AND
    CreateFile(L"Tempeicar.txt"....

    The filename does not follow FAT specification and MSDN documentations, but it works fine.

    hi, experts.
    I have a question about SetEvent().
    Will SetEvent() triger the system scheduler regardless whether there is a system_tick event or not?
    I mean will SetEvent() wake up WaitforSingleObject immediately? Or it just makes that event singled and goes on until it runs out its time-slice and then the scheduler wake up WaitforSingleObject?

    Hi Simon, yes, SetEvent can lead to an immediate reschedule without waiting for a system tick.
