AE安装检测(C++)
在MFC中使用AE(AO)进行二次开发时,当目标机器上若没有安装AE的Runtime,程序会直接挂掉。
对此,通过在CXXApp的InitInstance()的起始处增加环境的检测代码,来友好地提示用户安装AE的Runtime。
代码如下:
1 BOOL CMap2DApp::InitInstance() 2 { 3 CoInitialize(NULL); 4 5 try 6 { 7 IAoInitializePtr ipAoInitialize(CLSID_AoInitialize); 8 if (ipAoInitialize==NULL) 9 { 10 MessageBox(NULL,"请先安装ArcGIS Engine Runtime!","Map 2D",MB_OK|MB_ICONEXCLAMATION); 11 CoUninitialize(); 12 return FALSE; 13 } 14 esriLicenseStatus licenseStatus; 15 HRESULT hr = ipAoInitialize->Initialize(esriLicenseProductCodeEngine,&licenseStatus); 16 17 if (licenseStatus!=esriLicenseCheckedOut) 18 { 19 MessageBox(NULL,"请先安装ArcGIS Engine Runtime!","Map 2D",MB_OK|MB_ICONEXCLAMATION); 20 CoUninitialize(); 21 return FALSE; 22 } 23 } 24 catch (...) 25 { 26 MessageBox(NULL,"请先安装ArcGIS Engine Runtime!","Map 2D",MB_OK|MB_ICONEXCLAMATION); 27 CoUninitialize(); 28 return FALSE; 29 } 30 }
