loading the dll through arx application

waseefur.rahman — Thu, 21 Jun 2018 07:24:35 GMT

Hi,

I am trying to load the dll through arx application,

bool bLoads = acrxLoadModule(pathLvPty, true);

there are two dll which is being loaded in that one is successfully loaded, while other gives the error message as:
acrxGetApiVersion not found in e:\waseef\property_isolate.dll
Make sure the app links with rxapi.lib and export the symbol.AcRxDynamicLinker failed to load 'e:\waseef\property_isolate.dll
Can anyone please advice, where I need to change to load the dll successfully.

Thanks

Both dll's are arx/dbx files? If dll is mixed/managed application you have to load it such as:

1) LoadLibrary()
2) Also acdbmgd.lib export function LoadManagedDll:
enum Acad::ErrorStatus __stdcall LoadManagedDll(ACHAR const *path);
Sample:

enum Acad::ErrorStatus __stdcall LoadManagedDll(ACHAR const *path);
static int ads_netload(void)
{
  struct resbuf *pArgs = acedGetArgs () ;
  acedRetNil();
  if (pArgs && pArgs->restype == RTSTR) {
  Acad::ErrorStatus es = LoadManagedDll(pArgs->resval.rstring);
  if (es != Acad::eOk) {
     acutPrintf(_T("\nLoadManagedDll(\"%s\")=%s"),
        pArgs->resval.rstring,acadErrorStatusText(es));
  } else 
    acedRetStr(pArgs->resval.rstring);
  } 
  return (RSRSLT) ;
}

Hi @Alexander.Rivilis

I feel the there is mismatch in calling convention, instead of _stdcall, it should have _cdecl, I'm not sure if this is giving a compiler error for you.

enum Acad::ErrorStatus __stdcall LoadManagedDll(ACHAR const *path);
static int ads_netload(void)
{

The truth is somewhere in the middle:

AutoCAD 2019 x86:

?LoadManagedDll@@YG?AW4ErrorStatus@Acad@@PB_W@Z (enum Acad::ErrorStatus __stdcall LoadManagedDll(wchar_t const *))

AutoCAD 2019 x64:

?LoadManagedDll@@YA?AW4ErrorStatus@Acad@@PEB_W@Z (enum Acad::ErrorStatus __cdecl LoadManagedDll(wchar_t const *))

Hi Rivilis,

As when I add the Reference, it get some other error in my solution,
Could it be possible to load the Dll in command prompt itself,

I have done in .net to load the dll in command prompt itself, below is the coding.

ThisDrawing.SendCommand("FILEDIA" + vbCr & "0" + vbCr)
ThisDrawing.SendCommand("NETLOAD" + vbCr + "E:\waseef\property_isolation.dll" + vbCr)
ThisDrawing.SendCommand("FILEDIA" + vbCr & "1" + vbCr)

could you please advice how to achive the similar in C++.

Thanks

LoadManagedDll(L"E:\\waseef\\property_isolation.dll")

1. You have to insert definition of function LoadManagedDll as I posted above

2. You have to link with acdbmgd.lib
