使用：

Global Functions

AcRx Global Functions

  acrxLoadedApps

Include File

rxregsvc.h

void*

acrxLoadedApps();

This function returns a pointer to an AcDbVoidPtrArray that contains copies of the file names or URLs of all the currently loaded ObjectARX applications. These are the same strings that are reported by the AutoCAD ObjectARX command's "?" option.
It is the caller's responsibility to free all the strings in the array and to delete the array itself when finished with it.

获得当前加载的ARX应用程序。

下面给你个代码：

1. 
   
2. [FONT=courier new]
   
3. bool isModuleLoaded(const char* str)
   
4. {
   
5.         AcDbVoidPtrArray* pApps = reinterpret_cast<AcDbVoidPtrArray*>(acrxLoadedApps());
   
6.         if (pApps==NULL)
   
7.                 return false;
   
8.         bool bFound = false;
   
9.         for (int i=0;i<pApps->length();i++)
   
10.         {
    
11.                 if (stricmp(reinterpret_cast<const char*>(pApps->at(i)),str)==0)
    
12.                 {
    
13.                         bFound = true;
    
14.                         break;
    
15.                 }
    
16.         }
    
17.         for (;pApps->length()>0;)
    
18.         {
    
19.                 delete reinterpret_cast<char*>(pApps->at(0));
    
20.                 pApps->removeAt(0);
    
21.         }
    
22.         delete pApps;
    
23.         return bFound;
    
24. }
    
25. [/FONT]
