Programmatically saving the active document in C++/ARX applications   ‎以编程方式将活动文档保存在 C++/ARX 应用程序中‎
[code]void saveDwg()

{

try

{

IAcadApplicationPtr pApp =

acedGetAcadWinApp()->GetIDispatch(FALSE);

IAcadDocumentPtr pDoc;

pApp->get_ActiveDocument(&pDoc);

pDoc->Save();

}

catch(_com_error& e)

{

acutPrintf(_T("\nCOM error: %s"), (ACHAR*)e.Description());

}

}


Second Approach:



#include <acadi_i.c>

// minimal error check for code brevity

void saveDwg()

{

CWinApp* pWinApp = acedGetAcadWinApp();

if(!pWinApp)

  return;

CComPtr<IDispatch> pDisp = pWinApp->GetIDispatch(TRUE);

if(!pDisp)

  return;



CComPtr<IAcadApplication> pComApp;

HRESULT hr = pDisp->QueryInterface(IID_IAcadApplication,

  (void**)&pComApp);

if(FAILED(hr))

  return;



CComPtr<IAcadDocument> pDoc;

hr = pComApp->get_ActiveDocument(&pDoc);

if(FAILED(hr))

  return;



hr = pDoc->Save();

if(FAILED(hr))

  acutPrintf(_T("\nFailed to save current dwg file."));
