Aug 5, 2012 11:53 PM

When i try to use GetMousePosition() in my code, i got bellowing link error when compiling in VS2010.

 

Is there any library i can include to resolve it?

 

error LNK2019: unresolved external symbol __imp__GetCursorPos@4 referenced in function "struct tagPOINT __cdecl GetMousePosition(void)" (?GetMousePosition@@YA?AUtagPOINT@@XZ)

 

 

Thanks,

    Just had a look in the Mac 6 SDK. Have a look at the BasicDragDrop project.

    Yes, i searched it in the SDK sample BasicDragDrop as well. But i cannot fingure out why it works in SDK sample but not my CS6 project. The same code works well from CS3 to CS5.5.

     

    I guess it is related to project setting or some special linking files (e.g. .cpp or .lib), however, nothing special can be found in SDK sample BasicDragDrop.

    WSystemUtils.h includes the definition of GetMousePosition().

     

    inline SysPoint GetMousePosition() 

    {

              // ----- Returns mouse position in screen/global coordinates

     

     

              SysPoint pt;

              ::GetCursorPos( &pt ); 

              return pt;

    }

     

    The error means it needs the implement of GetCursorPos() which is invoked by GetMousePosition().

    Steps to reproduce the problem:

     

    1. New an empty project with name "test" using DollyXs on Windows;

    2. In testActionComponent.cpp, modify DoAbout() to be

    void testActionComponent::DoAbout()

    {

              GetMousePosition();

    }

    3. Build the project.

     

    Then, we will get bellowing link error

    1>     Creating library ..\..\..\build\win\objD\test/test.lib and object ..\..\..\build\win\objD\test/test.exp

    1>testActionComponent.obj : error LNK2019: unresolved external symbol __imp__GetCursorPos@4 referenced in function "private: void __thiscall testActionComponent::DoAbout(void)" (?DoAbout@testActionComponent@@AAEXXZ)

    1>..\debug_cs6\test.sdk.pln : fatal error LNK1120: 1 unresolved externals

     

    There is no such link error in the sdk sample BasicDragDrop.sdk.vcxproj, but i cannot find any special setting in its project property.

     

    Any suggestion will be appreciated.

     

    Thanks,

    Aidy

    The problem is resolved by using

     

    Utils<IEventUtils>()->GetGlobalMouseLocation();

    instead of

    GetMousePosition();


    Thanks a lot,

    Aidy
