请帮我看看这个代码有什么问题?

way

AcDbObjectId createLine()
{
AcGePoint3d startPoint(10.0,10.0,0.0);
AcGePoint3d endPoint(20.0,20.0,0.0);
AcDbLine *pLine=new AcDbLine(startPoint,endPoint);
AcDbBlockTable *pblocktable;
acdbCurDwg()->getBlockTable(pBlockTable,AcDb::kForRead);
AcDbBlockTableRecord *pBlockTableRecord;
pBlockTable->getAt(ACDB_MODEL_SPACE,pBlockTableRecord,AcDb::kForWrite);
pBlockTable->close();
AcDbObjectId lineId;
pBlockTableRecord->appendAcDbEntity(lineId,pLine);
pBlockTableRecord->close();
pLine->close() 编译时说:e:\ObjectARX 2004\ArxProject1\acrxEntryPoint.cpp(60): error C2601: “createLine” : 本地函数定义是非法的

我把你的程序在ARX2002下面编译了一下，没有发现你说的错误提示，看看你的程序里面是否包含了头文件“migrtion.h”，把上面这段代码第六行和第七行的pblocktable和pBlockTable改一下，在代码的最后还应该加上一句return lineId;这样就OK了，我在AutoCAD2002下运行成功了，并得到了一条直线。

上面是我的代码,有什么不对吗? 在VC.NET上写的2004ARX

JA_JERRY

我用的是ARX2002，你可以参照ObjectARX2002\docsamps\ents看一下你的代码，或者把完整的程序传上来，我也比较菜，只看代码找不出原因在哪

我和你的代码一样  出现的错误也差不多 为什么

sieben

这应该是常规情况下类的成员函数不能用作函数指针的问题！你把 createLine()函数定义成静态函数（如：static void createLine()），注意，你若想定义成一个命令，不应有返回值,

另外：

ACED_ARXCOMMAND_ENTRY_AUTO(CArxProject2App, ArxProject2, test, MyCommand1, ACRX_CMD_TRANSPARENT, createLine【你原来是NULL】)

还有，代码里AcDbCurDwg()应该是别人定义一个返回当前数据库的函数，但却没有看到，应该用acdbHostApplicationServices()->workingDatabase()来替代。

庞琛虹

居然把代码放在卸载ARX函数里面？？？？放在这里试试// TODO: Add your initialization code here

代码里AcDbCurDwg()应该是别人定义一个返回当前数据库的函数，但却没有看到，应该用acdbHostApplicationServices()->workingDatabase()来替代。  对的。。。。。

ACED_ARXCOMMAND_ENTRY_AUTO(CArxProject2App, ArxProject2, test, MyCommand1, ACRX_CMD_TRANSPARENT, createLine【你原来是NULL】)

对的。。。。。 

哈哈

楼主说的对  注意字母的大小写！
