three questions in opening and saving files!
three questions in opening and saving files!
i have three questions:
the first:
i hope to know the reason of the following error:
---------------------------
microsoft visual c++ runtime library
---------------------------
assertion failed!
program: c:\e-tech\xtpdm35\common\dwgdirecttest.exe
file: source\database\entities\dbentity.cpp
line: 1530
expression: invalid execution.
for information on how your program can cause an assertion
failure, see the visual c++ documentation on asserts
(press retry to debug the application - jit must be enabled)
---------------------------
终止(a) 重试(r) 忽略(i)
the second:
there is a linke error about the 搒caleby?function of 揙dgepoint3d?class in the dd_vc6md_ge.lib and there is no error about its 搑otateby?function.
the error is:
tdmtitle.obj : error lnk2001: unresolved external symbol "public: class odgepoint3d & __thiscall odgepoint3d::scaleby(double,class odgepoint3d const &)" (?scaleby@odgepoint3d@@qaeaav1@nabv1@@z)
the third:
when the function (oddbobject::dwginfields(pfiler)) is called, the following error occurs:
---------------------------
microsoft visual c++
---------------------------
unhandled exception in odamfcappdll.exe (dd_db.dll): 0xc0000005: access violation.
---------------------------
确定
---------------------------
i append the code and the drawing as accessory!
can you tell me the reason?
thanks!!
attached files
1. you have not include information on dwgdirect version. but probably assertion means that worlddraw() is called for an entity which has no worlddraw() implemented (check your custom entities).
2. link error means that the function is not implemented. btw, it is implemented in 1.14.02
3. impossible to answer without context. something is wrong with object, or filer, or ....
the code you attached is not enough to build a sample and reproduce the problem.

thanks for your answers;
dwgdirect version is 1.14.01.00;
for the third question, i think you could add these code files into
the "excustobjs_dll" project in the "allexamplesdll" workspace;
and then add " tdmstyleobj::rxinit();tdmframestyleobj::rxinit();
tdmframestyleobjblock::rxinit(); " in the "excustobjsmodule::initapp()"
function, like "excustobject" class do;
after building this dll, opening the appended dwg with the odamfcappdll.exe, you can get the error;
thanks!!!!

your stdafx.h is missing. also excustobjs sample does not use mfc and your classes use cstring.
compilable sample would be helpful.
