Acad menu doesn't show when ARX application is demand loaded at startup

newer

问题：
I have registered my ARX application using MFC to be demand loaded during
AutoCAD startup. My ARX application loads but the AutoCAD menu does not display
anymore. If I use MFC, why does everything work correctly?

解答：
This is caused because the following line in the 'InitModule()' function of your
ARX application is missing:


new CDynLinkLibrary (arxmfcDLL) ;
Here is the minimum InitModule() function you have to implement:

1. static AFX_EXTENSION_MODULE arxmfcDLL ;
   
2. 
   
3. extern BOOL InitModule (HINSTANCE hInstance, DWORD dwReason, LPVOID) {
   
4.     if ( dwReason == DLL_PROCESS_ATTACH ) {
   
5.         if ( !AfxInitExtensionModule (arxmfcDLL, hInstance) )
   
6.             return (0) ;
   
7.         new CDynLinkLibrary (arxmfcDLL) ;
   
8.     } else if ( dwReason == DLL_PROCESS_DETACH ) {
   
9.         AfxTermExtensionModule (arxmfcDLL) ;
   
10.     }
    
11.     return (1) ;
    
12. }
    

static AFX_EXTENSION_MODULE arxmfcDLL ;<br /> <br /> extern BOOL InitModule (HINSTANCE hInstance, DWORD dwReason, LPVOID) {<br />     if ( dwReason == DLL_PROCESS_ATTACH ) {<br />         if ( !AfxInitExtensionModule (arxmfcDLL, hInstance) )<br />             return (0) ;<br />         new CDynLinkLibrary (arxmfcDLL) ;<br />     } else if ( dwReason == DLL_PROCESS_DETACH ) {<br />         AfxTermExtensionModule (arxmfcDLL) ;<br />     }<br />     return (1) ;<br /> }<br />
