Autodesk ObjectARX

[#1]

We have a small arx program that adds a bunch of commands to AutoCAD.  I have recompiled the program using VS 2010, and the program works fine when loaded using appload (the commands register and work).  Now I am trying to autoload the program by adding registry entries in HKLM\SOFTWARE\Autodesk\AutoCAD\R19.0\ACAD-B005:409\Applications.  I am using 0x00000002 for LOADCTRLS.  On AutoCAD startup, none of the commands are registered.  When I check in the loaded applications list (appload), it shows that the program is loaded, but it is grayed out.  I dont see any errors in the Autocad message window on startup.  Any ideas on what could be wrong?

Does the (arx) function show that your ARX module is loaded? Have you checked the debugger output while the module loads?

Thanks that lead to the solution.  The arx function showed that the arx program was loaded, but the group wasn't.  I looked at the code and there was a section in AcRx::kInitAppMsg: where the comands would only be registered if the window was visible (if (::IsWindowVisible(adsw_acadMainWnd())){).  For some reason this returns false in AutoCAD 2013.  I commented this check out, and now it works.  Now I just have to figure out why this check was added :-)

Thanks!
