Open and Close Document Example (C++)

This examples shows how to instantiate a SolidWorks Document Manager session. It also gets the latest supported SolidWorks version number, and it opens an assembly document, lists the external references, and closes the assembly document.


#define WIN32_LEAN_AND_MEAN // Exclude rarely used stuff from Windows headers

#include <stdio.h>

#include <tchar.h>

#define _ATL_CSTRING_EXPLICIT_CONSTRUCTORS //Some CString constructors will be explicit

#include <windows.h>

#include <atlbase.h>

#include <iostream>

#include 'safearray.h' //Use the SafeArray class for VARIANT arrays as shown on the API Support Website

using namespace std;  //Use the standard C++ libraries for text output


#import 'C:\Program Files\Common Files\SolidWorks Shared\swdocumentmgr.dll'  raw_interfaces_only, raw_native_types, no_namespace, named_guids //Change as necessary


int _tmain(int argc, _TCHAR* argv[])  


//Initialize COM



CComPtr<ISwDMClassFactory> swClassFact;

CComPtr<ISwDMApplication> swDocMgr;

HRESULT hres = swClassFact.CoCreateInstance(__uuidof(SwDMClassFactory), NULL, CLSCTX_INPROC_SERVER );

CComBSTR Key = _T('your_license_key');  //Specify your license key

CComBSTR AsmDoc = _T('E:\\Assemblies\\Asm\\Assem1.sldasm');  //Replace with the name of your assembly (assuming it has one or more external references)

swClassFact->GetApplication(Key, &swDocMgr);

long ver = -1;



cout <<'The latest supported file version is: ' << ver << endl;


CComPtr<ISwDMDocument> swDoc;

SwDmDocumentOpenError res;

swDocMgr->GetDocument(AsmDoc, swDmDocumentAssembly,VARIANT_TRUE,  &res, &swDoc);


CComPtr<ISwDMSearchOption> pSrcOpt;



swDoc->GetAllExternalReferences(pSrcOpt, &Files);

CComBSTR Ref1 = FilesArray[0];  //First file reference (no particular order)




//Release references

pSrcOpt = NULL;

swDoc = NULL;

swDocMgr = NULL;

swClassFact = NULL;


//Uninitialize COM



return 0;
