11.2好郁闷啊！为何不能在mfc例程modeless中的对话框的控件响应函数中新建直线或公差操作？[br]想通过对话框实现用户选择公差相关数据，提交完后，我在图纸标出
//程序如下所示：
void CSampDialog::OnCancel()
{
//修改一：
CDialog::OnOK();
        runIt();


//以下为新建响应函数部分       
}
AcDbObjectId createFcf()
{

//AcGePoint3d center(90, 300, 0.0);
//急问：为何添加AcGePoint3d center(90, 300, 0.0);和pLine->setLocation(center);
//设置公差插入的位置，狂报错啊！
//note：1.错误见最后部分
//2.放到ents例子中画公差一点问题也没有
//3.放到mfc的contextmenu例子中也报同样的错啊，注释掉那两句后，没有错误啊！
AcDbFcf *pLine = new AcDbFcf();
pLine->setText("{\\Fgdt;a}%%v0.1%%v%%v%%v%%v");

//pLine->setLocation(center);

   AcDbBlockTable *pBlockTable;
    acdbHostApplicationServices()->workingDatabase()
        ->getSymbolTable(pBlockTable, AcDb::kForRead);

    AcDbBlockTableRecord *pBlockTableRecord;
    pBlockTable->getAt(ACDB_MODEL_SPACE, pBlockTableRecord,
        AcDb::kForWrite);
    pBlockTable->close();

    AcDbObjectId FcfId;
    pBlockTableRecord->appendAcDbEntity(FcfId, pLine);

    pBlockTableRecord->close();
    pLine->close();

    return FcfId;       

}
void createNewLayer()
{
    AcDbLayerTable *pLayerTable;
    acdbHostApplicationServices()->workingDatabase()
        ->getSymbolTable(pLayerTable, AcDb::kForWrite);

    AcDbLayerTableRecord *pLayerTableRecord =
        new AcDbLayerTableRecord;
    pLayerTableRecord->setName("ASDK_MYLAYER");

        // Defaults are used for other properties of
        // the layer if they are not otherwise specified.

        pLayerTable->add(pLayerTableRecord);
    pLayerTable->close();
    pLayerTableRecord->close();
}
void createGroup(AcDbObjectIdArray& objIds, char* pGroupName)
{
    AcDbGroup *pGroup = new AcDbGroup(pGroupName);

    for (int i = 0; i < objIds.length(); i++)
        {
        pGroup->append(objIds);
    }

    // Put the group in the group dictionary which resides
    // in the named object dictionary.
    //
    AcDbDictionary *pGroupDict;
    acdbHostApplicationServices()->workingDatabase()
        ->getGroupDictionary(pGroupDict, AcDb::kForWrite);

    AcDbObjectId pGroupId;
    pGroupDict->setAt(pGroupName, pGroup, pGroupId);
    pGroupDict->close();
    pGroup->close();
}


void runIt()
{
         createNewLayer();

    AcDbObjectIdArray idArr;

        idArr.append(createFcf());
   
    createGroup(idArr, "ASDK_TEST_GROUP");
}

lilin,goldlenshin...............,都能出书编大程序的人了，快帮我解答啊！

huangyhg

AcGePoint3d::AcGePoint3d(double,double,double)" (__imp_??0AcGePoint3d@@QAE@NNN@Z)
是类型定义错误吗？怎么办啦？

huangyhg

AcGePoint3d::AcGePoint3d(double,double,double)" (__imp_??0AcGePoint3d@@QAE@NNN@Z)
是类型定义错误吗？怎么办啦？

lilin

也应该是没有加入它LIB文件吧！试一试，应该是那样的

huangyhg

是的啊！问题已经全部搞定了，哈哈哈
lilin，你好可爱啊！

lilin

呵呵，对了。YY，你对DBX是不是很熟悉呀！我现在正在读关于DBX的书呢？不过是英文板的，特别难理解，

huangyhg

ObjectDBX allows you to write separate executables for the user-interface (UI) and database (DB) portions of your application.
是做ui还是db呢？我先学的vc，对纯ado数据库熟一点
我正打算学com组件

huangyhg

我将程序做成可复用组件，然后搭积木形式组装一个形位公差应用系统，底层是按照GPS规范做的数据库。不知你要做什么呢？
什么时候把我的程序传给你？帮我看看，怎么样？

lilin,你最近上哪去了？
