我的代码是这样的:bf.BlendFlags=0;
bf.BlendOp=AC_SRC_OVER;
bf.SourceConstantAlpha=100;
AlphaBlend(hdc,0,0,100,100,hmemdc,0,0,100,100,bf);编译错误:
vcpic.obj : error LNK2001: unresolved external symbol __imp__AlphaBlend@44
Debug/vcpic.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.为什么会这样?怎么办呢?谢谢!
