I just used the latest stable build, OSG 2.2.0, and I got a crash at precisely the same point. I do not think it is a versioning problem. Looking at the call stack, I wonder if there is something I am doing wrong with setting up memory, either in the OSG build, or in the managed code that uses the unmanaged code. I am new to VS2005 (have been using VS2003 for a long time), but I just followed the existing instructions, and everything compiles.
The call stack seems to have a problem with a dynamic cast: kernel32.dll!7c812a5b() [Frames below may be incorrect and/or missing, no symbols loaded for kernel32.dll] kernel32.dll!7c812a5b() ntdll.dll!7c9106eb() > msvcr80.dll!malloc(unsigned int size=3765269347) Line 163 + 0x63 bytes C msvcr80.dll!_CxxThrowException(void * pExceptionObject=0x0012ea24, const _s__ThrowInfo * pThrowInfo=0x781b55e0) Line 161 C++ msvcr80.dll!__RTDynamicCast(void * inptr=0xcd010001, long VfDelta=0, void * SrcType=0x005cb25c, void * TargetType=0x005cc438, int isReference=0) Line 315 C++ osg25-osgViewer.dll!005a1516() osg25-osgViewer.dll!005a1a69() msvcr80.dll!operator new(unsigned int size=1) Line 59 + 0x8 bytes C++ osg25-osgViewer.dll!005aa741() osg25-osgViewer.dll!005a1bfd() osg25-osg.dll!1007d866() [Managed to Native Transition] osgNETDemo.exe!osgNETDemo::osgNETDemoForm::InitOSG() Line 65 + 0x18 bytes C++ osgNETDemo.exe!osgNETDemo::osgNETDemoForm::osgNETDemoForm_Load(System::Object^ sender = 0x0012ec40, System::EventArgs^ e = 0x0012ec4c) Line 330 C++ Thanks Again -- Rick On Tue, Mar 18, 2008 at 2:30 AM, hesicong2006 <[EMAIL PROTECTED]> wrote: > I wrote the osgCppCLIDemo.rar.
