Re: [ARX函数]:调用函数打开文件失败,郁闷
最初由 EMeiMonkey 发布
[B]我增加了一个ARX命令,其类型为ACRX_CMD_MODAL | ACRX_CMD_NOINTERNALLOCK,然后在此命令中调用acDocManager->appContextOpenDocument(DwgFilePath);
老是失败,通过IAcadDocuments自动化接口打开文件直接死机,通?.. [/B]
下面是用ActiveX Automotion 接口,打开一个图形
- //MDI 模式下
- // 要保证用ACRX_CMD_SESSION bit注册命令
- //
- void openDwg()
- {
- 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;
-
- BSTR fName;
- hr = pDoc->get_Name(&fName);
- _bstr_t dwg1("Drawing1.dwg");
- _bstr_t dwg2(fName);
- if(SUCCEEDED(hr) && dwg1 == dwg2)
- {
- _variant_t vb(VARIANT_FALSE);
- _variant_t vnam(dwg1);
- hr = pDoc->Close(vb, vnam);
- if(FAILED(hr))
- {
- acutPrintf("\nFailed to close drawing1.dwg.");
- return;
- }
- }
- _bstr_t fileName("c:\\test.dwg");
- CComPtr<IAcadDocuments> pDocs;
- hr = pComApp->get_Documents(&pDocs);
- if(FAILED(hr))
- return;
- _variant_t b(VARIANT_FALSE);
- CComPtr<IAcadDocument> pDoc1;
- hr = pDocs->Open(fileName, b, &pDoc1);
- if(FAILED(hr))
- acutPrintf("\nFailed to open the dwg file.");
- }
- 非SDI 模式, 用下面代码//
- //
- void openDwg()
- {
- 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;
- _bstr_t fileName("c:\\test.dwg");
- hr = pDoc->Open(fileName, &pDoc);
- if(FAILED(hr))
- acutPrintf("\nFailed to open the dwg file.");
- }
