请问出现这样的问题该怎么办啊？？？？？？？？？？拜托，一定要帮忙啊
Compiling...entity.cpp
C:\Program Files\ACAD2000\adsrx\sample\entity\entity.cpp(93) : error C2660: 'createNewGroup' : function does not take 3 parameters
一定要救我啊
我只有一天时间了
程序如下：AcDbObjectId createNewLine();
AcDbObjectId createNewCircle();
AcDbObjectId createNewLayer();
void createNewGroup();
Acad::ErrorStatus changeColor(AcDbObjectId,Adesk::UInt16);
AcDbObjectId

pBlockTable->close();
AcDbObjectId lineId;
pBlockTableRecord->appendAcDbEntity(lineId,pLine);
pBlockTableRecord->close();
pLine->close();
return lineId;
}
AcDbObjectId
createNewCircle()
{

}
前面声明void createNewGroup(); 时就应该把参数也写上啊！
你程序第四行应该写成void creatNewGroup(AcDbObjectIdArray & objIds,char *pGroupName,AcDbObjectIdpLayerId);这样程序编译才能通过啊！
你前面声明是void createNewGroup(); 后面函数定义又带有三个参数，编译时当然会告诉你“createNewGroup' : function does not take 3 parameters ”啦！
谢谢，但是又有新问题了
啊又有了新的错误啊
C:\Program Files\ACAD2000\adsrx\sample\entity\entity.cpp(93) : error C2065: 'createNewGroup' : undeclared identifier
Error executing cl.exe.
entity.arx - 1 error(s), 0 warning(s)
程序错误原因：
本帖最后由 leeyeafu 于 2003-5-27 11:16:32 编辑第一，createNewGroup()函数声明与调用拼写不一致。你将该函数声明为void creatNewGroup()，而调用时用createNewGroup(),差一个字母e。不幸的是，你在程序开头将createNewGroup()函数声明为无参数的，再次写该函数的实现时，想要为该函数增加一个重载版本，但拼写错误使系统在调用时，只能找到无参数的函数版本，从而编译系统报告该函数不能使用三个参数。
第二，修改拼写错误后，编译仍有问题，系统报告第一个参数不能进行参数类型转换。这个错误大概是因为你对C++函数调用时参数传递机制的理解还有偏差。参数&idArray实际上只是一个AcDbObjectIdArray类型的指针，它不能转换为对AcDbObjectIdArray的地址引用。我将你的runIt()函数改写成这样：
void runIt()
{
AcDbObjectId newLayerId=createNewLayer();
AcDbObjectIdArray* idArray=new AcDbObjectIdArray();
idArray->append(createNewLine());
idArray->append(createNewCircle());
changeColor(idArray->first(),1);
changeColor(idArray->last(),3);
createNewGroup(*idArray,"MyNewGroup",newLayerId);
}
以上代码在VC6和VC++.NET中编译通过，且无任何警告信息。请注意我做的几处改动：
1、将idArray声明为指针。并用new运算符调用类AcDbObjectIdArray的构造函数给指针初始化。虽然VC编译系统并不要求你必须这样做，但一个未初始化的指针可能给程序带来的隐患不知你是否理解。关于这一点，一般高级点的C/C++教程应该都会提到。
2、既然idArray为指针，调用AcDbObjectIdArray类的成员函数就应该用 -> 运算符代替 . 运算符。
3、createNewGroup()函数的第一个参数用*idArray来传递数组的首地址。
要写好ARX程序，希望你能真正理解以上改动的必然性和其中的原理。有什么问题可以再发帖子询问。不过，有关C/C++的问题不妨到“源码分析”区提问。
多谢，多谢
实在是太感谢了你救了我一命啊
