Do you mean instead of letting the OS do it?

In my line of work I have times when I have to included existing code modules in with my new code. So happens this time I have an existing set of subroutines in a Fortran DLL that I need to access from my C++ Code. I can't get it to work following Microsoft's recommendations. Does anyone out there have any ideas the may work? For those of you who thing I should rewrite the Fortran in C++ it would take entirely too long to do that. I figure there are a few thousand lines of Fortran code.
Thanks,
George

Why not? What are the symptoms? Are the functions in the Fortran DLL exported? Are you importing them correctly in the C++ code?

The functions in the Fortran have the following: !DEC$ ATTRIBUTES DLLEXPORT :: INITIA
and the C++ code has this: extern "C" {void INITIA(int,int,int,int);}
There are a few of these since I'm trying to access eight routines in the DLL.
Everything is compiling just fine I just get LNK2019 error messages for all the routines I'm trying to use in the C++ code.

This must not be VS6. Correct?
Are you sure you have the correct signature for the exported function?

Correct. I'm running Visual Studio .NET 2003. I did some more searching on this site and came across an article by Shoalin Panda that may help me solve my problem. I'll let you know if it works.

Why not trying a LoadLibrary GetProcAddress sequence.
If you are able to get the function pointer, all you need afterward is to define it with the good calling convention.
To get the name of the function, try dumpbin or dependency walker

I don't think you are following Micro$oft's recommendations.
I just checked MSDN and it says to use __stdcall for FORTRAN functions.
For more info search for mixed-language programming in the MSDN docs.

Note, you don't *have* to use a DLL for this to work. You can simply link all the stuff together. You do have to take into account different parameter passing mechanisms (e.g., C++ strings do not map to Fortran strings!) but that is the same as if you use a DLL.
I don't remember all the details, though, so I'm useless. But I think if you have a Fortran compiler that links into Visual Studio (they exist), you can do this relatively painlessly.

The group I'm working on the code for wants it as a DLL so I don't have much of a choice.

I am new to C++. When would someone choose to use a static over a dynamic or the other way around?What exactly is the difference between to two? Thanks a lot

There are multiple things in C++ that can be 'static' or 'dynamic'. If none of the following match your situation, you should consider reposting and clarifying the context a little more. Like, "Where, in what context, were these words mentioned ?"
Most commonly, these two refer to the way a variable is stored in memory. When a variable is considered 'static', it is stored in the local stack memory. Each process that executes in a Win32 environment is allocated a piece of memory for it's private purposes. This memory is known as 'stack'. It cannot be directly accessed by any other application, it is private to the process in question. When a stack variable goes out-of-scope (a function where the variable was declared is finished), it is automatically destroyed and freed.
The alternative to 'static' variable is a 'dynamic' variable. At this point, the variable is stored in heap memory. This heap memory is considered all the RAM memory on your computer that is not process-specific. It is available for use by different processes. Each process can reserve a slice of this memory, use it to store a variable, and then release the memory when it is no longer needed. A heap variable never goes out-of-scope. You must manually reserve and release the associated memory. Failing to release memory will lead to memory leaks.
The actual C++ keyword, static, when used with a variable, creates a scope-independent variable. This means that when you create a static variable inside a function, and then at some point re-call this function, the variable is automatically initialized to the value it was when the last function execution ended. So to speak, the variable is not 'lost' when it goes out-of-scope.
All in all, I suggest you grab a good C++ -book and read it through with thought. C++ is quite difficult at start, but when you get a grasp of it, it becomes like a second language

If you are referring to the AppWizard's question about the MFC library, then it is asking if you want the MFC library completely embedded into your application or whether you want to access MFC via a DLL (Dynamically Linked Library). From a programming point of view, there is no difference.
Static linking makes the application more portable to weirdly configured machines (such as those with ancient MFC libraries or missing them altogether) but seriously increases the size of your application.

Hi,
I'm trying to prompt the user when he clicks close off my menubar (MFC SDI) so i set an OnFileCLose() function (using resources-tab), but when i run the program it does not enter the function, it just closes without hitting my messagebox.
i'm sure there's a very easy solution to this, if anyone has thoughts please let me know. I will owe you a coke.
thanks,
Mike

OnFileClose() is used to handle the File|Close operation, not File|Exit. The simplest way to handle the exit is to add a handler for the WM_SYSCOMMAND, and look for a parameter of SC_CLOSE. You can find the details in the MSDN[^].

Sorry, (File|Close) is actually what i am trying to do. I want it to close the current document and reset all the values. however when i click File->Close, the program exits and does not enter the OnFileClose function.

Hi,
I am able to get all the computers connected to a network.
Now my next step is to track the list of patches in these computers.
For this to achieve -pls advise me how to proceed.
Pls correct me if I am going wrong.
1.Detect type of OS on the target machine .
2.List the patches present on the target machine.
3.List out the dependancies of each patch.
For that-Do I need to know the list of softwares on the target machine?
-Do I need to know the list of service packages on the target machine?
-How a patch is detected on the target machine?
-How a patch is applicable on the target machine?
Regards

Do you mean like the ones listed here:

In order to list the patches present on the system -
I have to go through this path.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates\Windows 2000\SP5
But in my machine
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates\
I am able to see 3 entries-
Data Access
Windows 2000
Windows MEDIA pLAYER
And under Windows 2000 -I am seeing 2 entries SP4 and SP5.
And in the path -
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
I am able to get a list of hot fixes.
What are hot fixes and are these patched?
Regards

I was simply giving you that registry key as an example. It was not meant to be applicable on all systems.

Ok, and?

Updates that are sent out in between two normally scheduled updates (e.g., critical issue or vulnerability found).

I have a 3rd party program that when runs leaks memory in each call. The programm is running always. Is there any way to clean p the memory leaked by the program, any source help will be highly appreciated.

I suppose you dont have the source.
Contact 3rd party program creator , maybe he has a newer version.
If you have modification rights (i doubt) you can try to patch it at the assembly level

changed 3rd party if possible, more so if you're paying for it.
also, what do you mean by in each call ? each time you call it ? is it a DLL or something that you call an it allocate memory that you are in charge of freeing ?

If the program is allocating memory but failing to dealloocate it when done, there's nothing you can do about this. The code will need to be changed. Your only recourse would be to stop/start the program every once in a while so that Windows will clean up the mess.
