各位大神好。笔者最近在做关于sw二次开发的项目，遇到不少困难，望各位大神能给予解决。
以下代码是根据API手册里Traverse Assembly at Component and Feature Levels Using Recursion Example (C#)改写的，其实就是将C#换成c++，最终达成的目的是从装配体中遍历零件的特征。具体代码如下：

void Firstdialog::TraverseFeatureFeatures(CComPtr<IFeature> swFeat, long nLevel, CString* MyString)
{
CComPtr<IFeature> swSubFeat = NULL;
CComPtr<IFeature> swSubSubFeat = NULL;
CComPtr<IFeature>swSubSubSubFeat =NULL;
CComPtr<IFeature> pNextFeature = NULL;//定义特征对象
CString sPadStr = _T(" ") ;
BSTR B_FeatName;//定义组件的名称
BSTR B_FeatTypeName;
BSTR B_SubFeatName;//定义组件的名称
BSTR B_SubFeatTypeName;
BSTR B_SubSubFeatName;//定义组件的名称
BSTR B_SubSubFeatTypeName;
BSTR B_SubSubSubFeatName;//定义组件的名称
BSTR B_SubSubSubFeatTypeName;
long i = 0;
for (i = 0; i <= nLevel; i++)
{
sPadStr += " ";
}
while ((swFeat != NULL))
{
swFeat->get_Name(&B_FeatName);
swFeat->GetTypeName2(&B_FeatTypeName);
*MyString = *MyString + sPadStr + B_FeatName + _T(" [") + B_FeatTypeName + _T("]")+_T(":\n");
swFeat->IGetFirstSubFeature(&swSubFeat);
while ((swSubFeat != NULL))
{
swSubFeat->get_Name(&B_SubFeatName);
swSubFeat->GetTypeName2(&B_SubFeatTypeName);
*MyString = *MyString + sPadStr + B_SubFeatName + _T(" [") + B_SubFeatTypeName + _T("]")+_T(":\n");
swSubFeat->IGetFirstSubFeature(&swSubSubFeat);
while ((swSubSubFeat != NULL))
{
swSubSubFeat->get_Name(&B_SubSubFeatName);
swSubSubFeat->GetTypeName2(&B_SubSubFeatTypeName);
*MyString = *MyString + sPadStr + B_SubSubFeatName + _T(" [") + B_SubSubFeatTypeName + _T("]")+_T(":\n");
swSubSubFeat->IGetFirstSubFeature(&swSubSubSubFeat);
while ((swSubSubSubFeat != NULL))
{
swSubSubSubFeat->get_Name(&B_SubSubSubFeatName);
swSubSubSubFeat->GetTypeName2(&B_SubSubSubFeatTypeName);
*MyString = *MyString + sPadStr + B_SubSubSubFeatName + _T(" [") + B_SubSubSubFeatTypeName + _T("]")+_T(":\n");
pNextFeature = NULL;
swSubSubSubFeat->IGetNextSubFeature(&pNextFeature);
swSubSubSubFeat = NULL;
swSubSubSubFeat = pNextFeature;
pNextFeature = NULL;
}
pNextFeature = NULL;
swSubSubFeat->IGetNextSubFeature(&pNextFeature);
swSubSubFeat = NULL;
swSubSubFeat = pNextFeature;
pNextFeature = NULL;
}
pNextFeature = NULL;
swSubFeat->IGetNextSubFeature(&pNextFeature);
swSubFeat = NULL;
swSubFeat = pNextFeature;
pNextFeature = NULL;
}
pNextFeature = NULL;
swFeat->IGetNextFeature(&pNextFeature);
swFeat = NULL;
swFeat = pNextFeature;
pNextFeature = NULL;
}
}
void Firstdialog::TraverseComponentFeatures(CComPtr<IComponent2> swComp, long nLevel, CString* MyString)
{
CComPtr<IFeature> swFeat;
swComp->FirstFeature(&swFeat);
TraverseFeatureFeatures(swFeat, nLevel, MyString);
}
void Firstdialog::TraverseComponent(CComPtr<IComponent2> swComp, long nLevel, CString* MyString)
{
/*CComPtr<IComponent2> *swChildComp;*/
CString sPadStr = _T(" ") ;
int i = 0;
int nChildren;///定义子零件个数

}
