How to use Managed DLL in Unmanaged DLL and vice versa...
Arif Ali Saiyed
I was tring to create some dialogs with basic windows
controls like tabs,checkbox, picture control, buttons, URL links
etc....
I discovered that's it's very time copnsuming doing it pure Win32
way ... then I thought of exploring other technology/apps...
Delphi/ MFC/.NET
I discovered creating forms using .NET is very easy it's almost like
VB...where you just design what you want and code gets generated.....
In VS2008 I created a New Project-> Visual C++-> CLR ->Windows Form
Application .... and it worked fine
Now I wanted to create a ..NET DLL which would hold my all
dialogs ...provide some exported helper functions to invoke them from
pure Win32 Application or DLL
I created New Project-> Visual C++-> CLR ->Windows Form Control
Library.....
which does generate a DLL ...but I am not able to export any
function from this DLL
when I try to export any function
I get following two error
error C3389: __declspec(dllexport) cannot be used with /clr:pure or /
clr:safe
error C3395: 'myfunction' : __declspec(dllexport) cannot be applied to
a function with the __clrcall calling convention
how do i get of rid of this i went to propject properties and tried if
i could remove those flag /clr:pure and /clr:safe
but i could not find any option there....
I also want to used some exported structure ( which contain only
member variable and no functions)
of Win32 DLL...
This was first time ever i used .NET ..
Any URLs to learn how to do what i want to do , would be really
helpful....
Thanking you all in advance
