Hello ,
Have anyone experience with creating user DLL's for mathcad?
For me it was the first try and I have some problems
I started with the USERPACK demo as template to make the DLL.
The function works good until I load a DLL in the mathcad DLL.
I load the DLL with the LoadLibrary function and for the pointer to
the function I want to call with the GetProcAddress function.
In Mathcad I have seen two errors:
internal error 0xC0000005
general protection error
If I comment out the call to the function , the function gives no errors
in mathcad.
Is it possible to load a DLL inside a DLL?
Have anyone tried to use a second DLL in an user DLL for mathcad?
How to use the debugger for an user DLL in mathcad?
I used:
Microsoft C++ compiler v11 (visual studio 97)
OS = NT4 SR3
Thanks,
Nico Willems
