c#调用C++api参数对应
Dword DrawBarcode(Hdc DC,WCHAR* TEXT,WCHAR* Starstopchar,Wchar* facename,Wchar* buffer,Rect* bounds,RECT* barcodematrix,int textwidth,int texheight,int textbobarcode,int textquiezone,int barinflate,Dword color,Dword params)
DoResult = DrawBarcode(0 , L"692345065618", L"A>", L"Arial",
                     NULL, &rect, Matrix, 8, 24, 4, 24, 0, 0, Params);

vc 调用的参数
DWORD Params = 0x00731000 | (DWORD)NamesList.GetCurSel();// 1-35正整数
SetRect(&rect, 10, 10, 288, 144);
dc.FillSolidRect(rect,RGB(255,255,255));
RECT  Matrix[512];
  OffsetRect(&rect, 0, 144);
