What is the problem in mixing managed and native terminologies? Confused | :confused:

Especially given the context of this thread, what else other than using a DLL (COM Interoperability) can be a sensible way to consume something written in managed code, if I am on the native code side?

INTEROPERABILITY, nothing else. My guess was that the OP was developing the dll in the managed environment.

You need to google first, if you have "It's urgent please" mentioned in your question.

There is nothing like a VS 2008 DLL and a VS 6.0 DLL. Once built, a DLL is just a DLL with no regards to the languages/tools used to build it.[^]

Well yes and no. If the VS 2008 DLL used dynamically linked MFC, you will likely have problems. If the VS 2008 DLL dynamically linked to the CRT, I'm not sure what the behavior is if you allocate memory in one and free it in the other.

Anyone who thinks he has a better idea of what's good for people than people do is a swine.

It has nothing to do with the 'DLL' terminology. If I link dynamically to a third party library from a DLL written with VS6 environment, that would depend on the third party library. This does not mean that a DLL written in VS6 will ALWAYS depend on that third party library.

In other words, you are kinda marrying a DLL with what it is linking to. I was pointing out that a DLL is just well, a DLL.

This forum is for asking specific questions on C++/MFC. If you don't know anything about C++, the ideal way to learn C++ would be to buy a C++ book and read it.

Thinking in C++[^] is an excellent book and the link takes you to a page where you can legally download an electronic copy (both part 1 and part 2) of it for free.

It would be of great help if you can get the architecture of the application, and the sequence diagrams for your study. This would boost your understanding and decrease the time you would invest in understanding C++ API's which you are not going to use.

Have a look at CDialog::DoModal()[^]

In your dialog based application create the main dialog for taking the user input for id and password.
Check and validate the password. If they are correct,

if(bIsPasswordCorrect)
{
CMYDlg myDlg;
myDlg.DoModal();
}
set bIsPasswordCorrect to true only if the credentials are correct.
