I'm trying to share a C++ DLL between a C++ application and a C# application, but a DLL variable is being reset between invocations. Can anyone suggest what I may be doing wrong?
1. The C++ app calls a DLL function.
2. Then the C++ app starts a C# app (with a system () call) that sets a variable to a nonzero value in the same (?) DLL.
3. The C# app terminates.
4. Then the original C++ app looks at the DLL variable and finds it has been magically "reset" to its original zero value. (?!)
I'm assuming there's only ONE instance of the DLL, which is loaded into memory in Step 1. The DLL variable SHOULD BE nonzero in Step 4, but it's not. Any ideas what's going wrong? Thanks!

That's wrong. Each process has a copy of the DLL in its own address space. If you need to share memory , then have a look at [^].

Hi, all! How can I encrypt/decrypt some data with OpenSSL library and send/receive it using WSASend and WSARecv? I need it for FTPS...

Actually 2 questions. 
1. In CFileDialog, is the edit control ID 1148 or 1152 under Windows XP?
2. Is the ID still the same in Vista?
I'm trying to use SetControlText to set the file extension automatically when user selects the file type dropdown.

I don't know how to do this, but I bet you'll spend an awful lot of time hassling with this. Is there a reason you need to do this? Normally you would just wait till the user successfully closes the dialog and then get the extension and file name from the CFileDialog.

A lot of applications have this behavior. For example, Adobe Photoshop, in the Save As dialog, if you choose a different file type, say JPG, it would automatically set your file name to be "mypicture.jpg". If you choose BMP, it would change it to "mypicture.bmp".

That's true Adobe does do that. But the thing is that you're having to work around or fight the system. In doing so you're causing a hassle for yourself and for the folks at Microsoft. Go read some of the articles at the "Old New Thing" - it's full of stuff like this. What if Microsoft changes the ID? Then your code is broken. Or they change to a different technique or control? All I'm saying is that, unless there's an easy way to do this, and I don't think there is (I could be wrong), that you're fighting something and spending your time on stuff that could likely be more profitably spent doing something else.

Create your own file dialog class derived from CFileDialog and override the virutal member OnTypeChange. That member is called when the selection in the type box is changed.

Per Spy++, it is 0x480, or edt1 from dlgs.h.

Hey David,

Hi there
In C# is a method WriteLine in Debug class. How can I do that in a MFC win32 application.

Assuming a non-GUI application, try WriteConsole() or WriteConsoleOutput().
If, however, you are referring to the debug window within the IDE, check out TRACE().

first of all, it seems that you don't exactly know what you're talking about :
duta wrote: in a MFC win32 application
even though MFC is built upon Win32, an application is either MFC or Win32, not both.
moreover, even though it is possible to have a console in a MFC program, it is a framework designed for window oriented applications.
so to reply, but not to you exact question, you still can always use the C++ mechanisms to output to the standard stream :
std::cout << "Hello World !";

Actually that's not entirely correct. You can change your linker settings from /subsystem:WINDOWS to /subsystem:CONSOLE and you will get a console.

that's why i said "even though it is possible to have a console in a MFC program", but i felt the post owner wasn't that far in learning C++/MFC...

Damn you got me!  Helps to read all the way to the end!

many thx for your posts.
I've tried to switch to system:/console but I have this error:
error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup

So do you have a main() function?
