那位有shape文件生成的c++代码(或第3方库)?

[AsongWam]

//创建SHAPE图层函数
void CCreateShapeDlg::CreateShpFile(CString &strPath, CString &strFile)
{
//创建shp，

UpdateData();
CComBSTR bsFolder=strPath;
CComBSTR bsName=strFile; //不要加Shp后缀
CComBSTR bsShapeFieldName=strFile;
m_geoType = (esriGeometryType)atoi(m_strGeotype);

IFeatureWorkspacePtr ipFeatureWork;
IWorkspacePtr ipWorkSpace;
IWorkspaceFactoryPtr ipWorkFact(__uuidof(ShapefileWorkspaceFactory));
ipWorkFact->OpenFromFile(bsFolder,NULL,&ipWorkSpace);
ipFeatureWork = ipWorkSpace;

IFieldsPtr ipFields(__uuidof(Fields));
IFieldsEditPtr ipFieldsEdit; //用于编辑Fields
ipFieldsEdit = ipFields;

IFieldPtr ipField(__uuidof(Field));
IFieldEditPtr ipFieldEdit;
ipFieldEdit = ipField;

ipFieldEdit->put_Name(bsShapeFieldName);
ipFieldEdit->put_Type(esriFieldTypeGeometry);

IGeometryDefPtr ipGeoDef(__uuidof(GeometryDef));
IGeometryDefEditPtr ipGeoDefEdit;
ipGeoDefEdit = ipGeoDef;
ipGeoDefEdit->put_GeometryType(m_geoType);
// ISpatialReferencePtr sr(__uuidof(UnknownCoordinateSystem));

ISpatialReferencePtr ipSpatialRefe(__uuidof(GeographicCoordinateSystem));
// IGeographicCoordinateSystemPtr gcs(__uuidof(GeographicCoordinateSystem));
IGeographicCoordinateSystemPtr ipGeographCoorSys;
ipGeographCoorSys = ipSpatialRefe;

IGeographicCoordinateSystemEditPtr ipGeographCoorSysEdit;
ipGeographCoorSysEdit = ipGeographCoorSys;

VARIANT var1,var2,var3;
CComBSTR bstr;

bstr = m_strSparef;
var1.vt=VT_BSTR;
var1.bstrVal=bstr;//esriSRGeoCS_WGS1984;
var2.vt=VT_BSTR;
var2.bstrVal=bstr;
var3.vt=VT_NULL;

ipGeographCoorSysEdit->Define(&var1,&var2,&var3,&var3,&var3,&var3,&var3,&var3);

ipSpatialRefe->SetDomain(0,21474.83645,0,21474.83645);
ipSpatialRefe->SetFalseOriginAndUnits(0,0,100000);


ipGeoDefEdit->putref_SpatialReference(ipSpatialRefe);

ipFieldEdit->putref_GeometryDef(ipGeoDef);
ipFieldsEdit->AddField(ipField);

//添加其他字段
ipField = NULL;
ipField.CreateInstance(CLSID_Field);
ipFieldEdit = ipField;
ipFieldEdit->put_Length(30);
ipFieldEdit->put_Name(L"MiscText");
ipFieldEdit->put_Type(esriFieldTypeString);

ipFieldsEdit->AddField(ipField);

IFeatureClassPtr ipFeatureCls;
ipFeatureWork->CreateFeatureClass(bsName,ipFields,NULL,NULL,esriFTSimple,bsShapeFieldName,L"",&ipFeatureCls);

}

这是创建SHP文件的函数，怎么用，你自己再琢磨一下吧。

不用arcgis,脱离任何商业平台,最好用才c\c++直接生成

[AsongWam]

这是用VC++下AE开发的,编译以后可以脱离ARCGIS平台.

[AsongWam]

AE的二次开发,但要引入所有需要用到的接口的组件库.
