MFC dll in MAC

Hello,
I have a JNI native method, that interacts with a VC++ dll. So I wrotea MFC dll to establish connection between my Java program and that VC++ dll. It works just fine. What do I do if I have to port my Java application so that it runs on Mac ??
Thanks a lot !!

No, it's not possible. DLLs don't work on mac. As soon as you start using JNI, you loose java's portability and you have to rewrite (or at least recompile) all the native code for each platform you intend to support. To run on mac, you'd have to compile a mac-form shared library (don't know what they're called on mac). If you can find a VC++ compiler for mac that deals correctly with MFC (doesn't sound very likely), then you may be able to just recompile your native code. Otherwise, you'll have to rewrite it in a language that mac supports. I think cotton's right--reach for the kleenex.

Problem: Socket connection is not creating in machine, through utility program (MFC Dll), on ListDisplay service port - 3334 (on separate machine), while we are able to telnet on same ListDisplay service port - 3334 from same issue machine on same time

Problem: Socket
connection is not creating in machine, through utility program (MFC Dll), on ListDisplay service port - 3334 (on separate machine), while we are able to telnet on same ListDisplay service port - 3334 from same issue machine on same time
Environment: -
OS:
Windows XP SP2/7
Code:
VC 6.0
Dll: MFC
Problem Description: -
We have written a utility program which create socket (Using windows standard method [MFC]), and then make connection with another service (List Display) running
on port 3334 in different machine and retrieve the required list data. This program was working fine in almost all the machines.
But, we have received a severe intermittent issue on two machines. Client is facing issue in displaying the list data from port 3334.
Attempt: -
First we tried to debug code, and we come to know that socket is not creating in utility program. So we tried to telnet on ListDisplay service port 3334 and we were surprised that we were able to telnet, then we opened some more
telnet window on same port 3334 around (6 to 8) window, and each cmd connected properly. But we were not able to create socket from utility program.
Problem is severe because issue is intermittent.
We have tried all the way, but we are not able to figure it out, that what can be the exact problem and what are the conditions, when utility program will not
connect with ListDisplay service on port 3334.
Kindly assist to resolve this issue. For any help, we would be really thankful.

Hi,
According to your description, it seems that you have created an utility program which is making connection with another service port 3334, however, two clients are facing issue in display the data list from port 3334.
Port: 3334/TCP
3334/TCP - Known port assignments (1 record found)
Service
Details
Source
directv-web
Direct TV Webcasting
IANA
Since the port 3334 is used by directv-web service, I'd like to suggest check this service it is working well on the problematic clients.
1. The client can be resolved in DNS well? Please run "nslookup" in the prompt command.
2. Is there any 3rd party application interrupting? Do test in clean boot.
2. Strongly suggest you run process monitor tool to analysis it.
I am looking forward to your reply if you have any updated on your side.

Palm Desktop Fails at startup wiht AppName: palm.exe AppVer: 4.1.4.0 ModName: mfc.dll

Folks, Wifes phone appears to have something wrong with the address book. When she syncs to the palm desk top we get the following error at palm desktop startup : Palm Desktop Fails at startup wiht AppName: palm.exe AppVer: 4.1.4.0 ModName: mfc.dll .
If i remove the address folder the desktop works until we sync again. Help!

There may be database corruption causing the issue. Click on the following link for the program called DbFixiT. This program has a trial version that you can download and install on your Palm OS device. The trial version will scan for database corruption and then report the corruption. You can then find the records causing the problem and fix them yourself or you can purchase the program and have it automatically fix the records.
http://www.pimlicosoftware.com/dbfixit.htm
Remove the address folder like you did so you can start up palm desktop. Sync DBfixit to the phone using quick install. Scan for db corruption on the device and Blobs in the calendar. After that is done, sync the Treo to the PC with the conduits set at handheld overwrites desktop. This will create a new "clean" address book on the PC and this should allow Palm desktop to open correctly.
For reference purposes, click on the following link for the support page for your device on the kb.palm.com webpage.

Debbugging MFC DLL with TestStand.

I am in the process of evaluating TestStand and am very impressed with the tool. I created an MFC DLL with my existing C++ test code and have succesfully executed it through Teststand using the flexible prototype adapter. What seems to be missing is the ability to debug the DLL in Visual studio. I'm not sure if I need to have Visual Studio reference TestStand for DLL testing or visa versa. Please advise, as this is the last item I need to confirm prior to purchase. Is this a feature on version 2.0 ?? Thanks in advance.

Mark-
You can debug DLLs from TestStand that were created as debuggable DLLS in their original ADE by launching the TestStand Sequence Editor (\TestStand\Bin\SeqEdit.exe) from within your DLL's ADE. In your case you would run the SeqEdit.exe as an external process from within the Visual C++ development environment.
Here is the description of how to do this from pg 12-12 in the TestStand User Manual that should already be installed on your computer under Start>>Programs>>National Instruments TestStand>>Online Help
"To debug a DLL, create the DLL with debugging enabled in
LabWindows/CVI or in another ADE. To debug DLLs, you must launch
the sequence editor or run-time operator interface from LabWindows/CVI
or the other ADE. In LabWindows/CVI, you use the Select
External
Process command in the Run menu of the Project window to identify the
executable for the sequence editor or run-time operator interface. You then
use the Run command to start the executable.
If you select the Step Into command in TestStand while execution is
currently suspended on a step that calls into a LabWindows/CVI DLL that
you are debugging, LabWindows/CVI breaks at the first statement in the
DLL function."
Hope this helps!

Add num edit control to existing MFC DLL

Hi,
I'm using Visual C++ 6.0 and Visual Studio 6.0 SP3, with Measurement Studio 6.0.0 (eval version).
I have a C++ DLL which is using shared MFC. It holds various dialogs that my app needs. Onto the waveform dialog, I want to add NI graph (not 3D graph) and num edit controls.
I looked at the tutorial for "Manually Adding Components to My MFC-Based Project" but it seems that the additional steps don't apply to either of the controls I'm adding.
Currently my waveform dialog contains only VS controls, and it works as expected both in the Visual Studio debugger and outside of it.
So in the Visual Studio resource editor, I right-click, select "Insert ActiveX Control", and select the "CWNumEdit Control (National Instruments)", and the path shown is "C:\\Windows\system32\cwui.ocx". I change its style so it looks like the classic control, and change its name. My project builds and links with no additional header files or libs added to the project.*
Now I run my app in the Visual Studio Debugger. But when I call the code to create an instance of my dialog, it returns a 0 instead of a handle (indicating that it failed to create the object). (I can't step into the call to create the dialog.) But when I call GetLastError() it returns a 0, indicating no error!
*I believe I at some point had some old Measurement Studio stuff loaded, which apparently had come along with other National Instruments installs that I had done. Is that possibly confusing my compile/link?
What am I missing? Thanks in advance for any help ...

Hi B.Anderson,
You may be missing some components to your project. Here's a thorough KnowledgeBase article that discusses this:
Adding Measurement Studio Controls to an MFC Project in Microsoft Visual C++
If going through that doesn't help. Could you post a section of your code that is causing the problem and also show what libraries you have included?
Take care!

How to call MFC Dll Dialog

Hi,
I have created a MFC regular dialog as a dll(TestDialog). And exposed the entire class. Did not expose any specific member function.
Then i created one more MFC dialog based exe and trying to call my dll.
I did the below settings:

Include : header file
Now i am calling as
CTestDialog dlg;
m_pMainWnd = &dlg;
dlg.DoModal().
I am not getting any dialog.
Can anyone please help me on this.

sorry it maybe because of zip file.
i will write a step.
just simple.

MFC - is there any way, to make the MFC work on Mac OS X

Hello,
I'm new to programming on Mac OS X. And I just want to know, if there is a way to compile the MFC (M$ Foundation Classes) for OS X?
Or is there any other possibility to use them?
I searched in different Forums, asked Mr Google, but didn't find a good answer.
Well, I didn't find a positive answer...
Maybe someone here, has any idea about it or a hint, that can help. A simple NO is not enough...
THX tobschwe

Well, the last time I looked, the underlying MFC concepts aren't totally foreign to OS X. You could probably (with SUBSTANTIAL effort) write a package that presents the MFC API, but implements it in Cocoa. But that's what you'd have to do, because Cocoa has none of the underlying library functions used by MFC's Windows implementation, and the Cocoa implementations of the underlying concepts and the relationships between them vary in subtle ways from the Windows implementations.
Which is why wise men simply say "NO".

MFC Extension DLL or MFC DLL with "Automation"

I've been planning a project for quite some time now that uses MFC code and is heavily object oriented. A couple MFC applications run on top of the dll formed platform and draw on various functional objects stored in a DLL. For the time being, I've been
struggling to get them to link together, so I was wondering what kind of DLL I should use.
Both Extension DLL's and the feature automation have their merits. But when the Extension DLL is selected, the Automation option is greyed out. What exactly is the difference and which one would be better to use.
Until such a time I attempt to port the project over to another platform, I don't intend to use non-MFC software run on top of these libraries so non-MFC shouldn't be an issue.

If you want to build automation components, you'll want to use a regular DLL.
The following help topics might help clarify:
Extension DLLs
Using Database, OLE, and Socket Extension DLL's in Regular DLLs
Think of it this way. An extension DLL extends MFC, so can only be utilized by an MFC based application.But a COM DLL is a stand alone component, that can be utilized by non-MFC applications, which by definition precludes them from being extension
DLL's.
Sincerely,
Ed Dore

Issue in using DLLs from a VC++ 6.0 MFC application

Hi,
I am using Labview 7.1 for creating VIs.I have created DLLs for accessing
these
VIs from a VC++ application. The VC++ 6.0 project is created using MFC app
wizard. When I try to execute the VC++ project in Debug configuration it
works
fine. When I try to execute the same in release configuration I get an
error as
shown in the attachment.

Hi Mukund!
I found this response on another forum thread that looked like it could help you out:
==============================================================
MSVC++ error (system error 998)
This is actually a Microsoft issue. It has something to do with static and
dynamic linking of the MFC DLL. Our R&D engineers have verified this with projects created with no LabVIEW code at all (that is why we believe it to be solely a Microsoft issue). There are three options at this time:
1. Link with the DLL form of MFC.
2. Do not link with the .lib from the LV DLL, instead use LoadLibrary and GetProcAddress to dynamically load the DLL and call the function.
3. Use the VC delayload feature to make the LV DLL not get loaded until the first call is made into it. See VC help on "delayload" for information on setting this up.

Using NI controls in a DLL running from a non-MFC application

Hello,
I am developing a DLL library for use with a non-MFC third party application. The DLL I am currently working on displays a MFC dialog, and works fine from the third party app, as long as I don't add any NI Measurement Studio controls. When I add in a CNiGraph control, the dialog window can't be created.
Does anyone have any suggestoins about this?
Thanks,
-Robert

Hello Robert,
The setup that you have here sounds perfectly valid and should have no errors. The firts thing to check is that you have enabled support for ActiveX in your MFC DLL. When you run the new project wizard one of the options is to enable ActiveX this adds some initialization code to enable the ActiveX container.
You can test this by adding any other ActiveX control to your dll and give it a try. If you get the same error then most likely the ActiveX container is not properly initilized.
Let me know how this goes.

Get TS_Err_DLLNotLoadable(-17004) using MFC Regular DLL

I made a regular MFC dll and tried to load it from TestStand 3.0. I got "-17004; Could not load DLL or library." Any ideas? Thanks.

zZn -
There must be some dependency that the DLL has to another DLL that cannot be resolved or DLLMain is returning an error. Use depends.exe to determine any DLL dependencies, and if you have defined a DLLMain, try to step through it to see what might be happening.

How to create dll in Visual Studio 2008 in Visual C++

Hello,
I have insatlled Visual Studio 2008. I have to create DLL in Project
type Visual C++.
Which Template i have to select to reate dll, MFC DLL or Class
Library?.
I have to call or import this dll in Windows Forms Application. How
can i do this. Please give details procedure to do this.

If we look at how AFX_CLASS_EXPORT and AFX_CLASS_IMPORT are defined in afxv_dll.h we see the following.
#define AFX_CLASS_EXPORT __declspec(dllexport)
#define AFX_CLASS_IMPORT __declspec(dllimport)
So, when exporting our classes from our DLL we want the class declarations from the DLL to look like this:-
class __declspec(dllexport) CMyClass : public CObject
And, when importing our C++ classes into our application we want the class declarations from the DLL to look like this:-
class __declspec(dllimport) CMyClass : public CObject
OK, so here's how I do things.
In the stdafx.h file for the export DLL, include two #defines at the bottom of the file like this:-
#define _MYLIB_DLLAPI_
#define _MYLIB_NOAUTOLIB_
Now, in the main header file for your DLL, say mylib.h (the main 'point of entry' header for your DLL that you will include in you application later), add the following at the top:-
// The following will ensure that we are exporting our C++ classes when
// building the DLL and importing the classes when build an application
// using this DLL.
#ifdef _MYLIB_DLLAPI_
#define MYLIB_DLLAPI __declspec( dllexport )
#else
#define MYLIB_DLLAPI __declspec( dllimport )
#endif
// The following will ensure that when building an application (or another
// DLL) using this DLL, the appropriate .LIB file will automatically be used
// when linking.
#ifndef _MYLIB_NOAUTOLIB_
#ifdef _DEBUG
#pragma comment(lib, "mylibd.lib")
#else
#pragma comment(lib, "mylib.lib")
#endif
#endif
Now, just declare all the C++ classes you want exported from the DLL like this:-
(Note: Any C++ classes not declared with MYLIB_DLLAPI will not be exported from the DLL)
class MYLIB_DLLAPI CMyClass : public CObject

Matt John
