markov, Roger, i'm sorry, i think i did not clearly explain what my Problem was. I managed to get everything together except the Linker, Input, Additional Dependencies -> uictrls.lib. It works now, thanks to markov and Roger! Maybe this is helpful for other CHook Programmers that switch to VS 2008. Regards, Andreas

Hi, i'm having trouble with Visual Studio 2008 Standard Edition. If i write the "Simplest C-Hook" from CHook Dev. Guide i get some Compiler errors: First: Error C1083, "UIEditReal.h" cannot be opened. I figured out to add the Path C:mcamxsdkinterfacesUICtrls to the Include Directories. The next i get is error C2664, i have to change 'Messagebox(0, "Hello from Mastercam ...' to 'Messagebox(0, L"Hello from Mastercam ..." and so on, this is because of UNICODE instead of Multi-Byte in the Default Projectproperties. After that i get this 3 errors: Fehler 2 error LNK2019: Verweis auf nicht aufgelöstes externes Symbol ""public: virtual __thiscall UIDataTip::~UIDataTip(void)" (??1UIDataTip@@UAE@XZ)" in Funktion ""public: virtual void * __thiscall UIDataTip::`scalar deleting destructor'(unsigned int)" (??_GUIDataTip@@UAEPAXI@Z)". CHookSample.obj CHookSample Fehler 3 error LNK2019: Verweis auf nicht aufgelöstes externes Symbol ""public: virtual __thiscall UIErrorTip::~UIErrorTip(void)" (??1UIErrorTip@@UAE@XZ)" in Funktion ""public: virtual void * __thiscall UIErrorTip::`scalar deleting destructor'(unsigned int)" (??_GUIErrorTip@@UAEPAXI@Z)". CHookSample.obj CHookSample Fehler 4 fatal error LNK1120: 2 nicht aufgelöste externe Verweise. Release/CHookSample.dll CHookSample I think i need help here to finish the my first CHook with Visual Studio 2008. Regards, Andreas

Thanks Roger! I think i can do that Spline on my own now. Regards, Andreas

Yes, Curvature was the word. First of all, thanks for the Info. I looked into the nethook.dll with the Object Browser from my Visual Studio and found a CSpline Function. From that description is the Term Curvature. So i cannot create a Spline with a Nethook, can i do that if i write a C-Hook with MFC and C/C++ ? And how do i do that, whats the Function ?

have got a question about the CSpline Function because i am writing a NetHook with Visual Basic. I want to do a Spline through several Points but I couldn’t figure out how to do that with the CSpline Function and i only have a lot of Points. In Detail I don’t know what Curvatore means. Do I have to recalculate my Spline in Polynomical notation ?
