Innovate. Integrate. Automate
By Virupaksha Aithal
You can use “acedPutSym” API to set the AutoLISP symbol and “acedGetSym” API to retrieves the value of a AutoLISP symbol.
//set the MySymbol value
struct resbuf *rb = acutBuildList(RTSTR,
_T("Unicode String"), RTNONE);
int res = acedPutSym(_T("MySymbol"), rb);
acutRelRb(rb);
//get back the text
rb = NULL;
int rc = acedGetSym(_T("MySymbol"), &rb);
acutPrintf(L"MySymbol value is %sn", rb->resval.rstring);
acutRelRb(rb);
What is the .net equivalent of acedGetSym ?

I tried with the below code , but its giving error —- “Unable to find an entry point named ‘acedGetSym’ in DLL ‘acad.exe’.
[System.Security.SuppressUnmanagedCodeSecurity]
[DllImport(“acad.exe”, CharSet = CharSet.Unicode, CallingConvention = CallingConvention.Cdecl, EntryPoint = “acedGetSym”)]
extern static private int acedGetSym(string args, out IntPtr result);
static public ResultBuffer AcadGetSym(string varname, ref int stat)
{
IntPtr rb = IntPtr.Zero;
stat = acedGetSym(varname, out rb);
if (stat == (int)PromptStatus.OK && rb != IntPtr.Zero)
return (ResultBuffer)DisposableWrapper.Create(typeof(ResultBuffer), rb, true);
return null;
}
I am using AutoCAD 2014 and Visual Studio 2010 on windows 7 64 bit machine.
Hi ,
Please import the acedGetSym from accore.dll instead of acad.exe
Thanks

Hello Virupaksha,
Has the location of acedGetSym been changed for AutoCAD 2015, 32 bit?
I get an error that acedGetSym cannot be found in acCore.dll when i run code that uses acedGetSym.
The same code runs fine in 32 bit AutoCAD 2013 and 2014. The same code also runs correctly in 64-bit versions of AutoCAD 2013 to 2015.
I’ve posted the same question to the AutoDesk forms and to theswamp.org, but i haven’t gotten any good replies.

I would appreciate any insights you might have on this issue.
Thanks!
