Revising my judgment... Smile | :)

Mfc42.dll is automatically installed in the windows directory if you install win98/XP that is why you don't need to attach this file to your CD. Because if the user has win98/XP installed it means he already has this dll file.
I've done it many times and have never experienced problems.
As mfc71.dll was released after win98/xp , thats why you'll have to attach this file to CD if you are building your app in C++.Net 2003

i still don't agree.

if MFC is already install, it has 2 reasons for me :

1. Visual studio is installed on the computer
2. Another application already copied the libraries to the computer

if you format and install windows wathever version, try executing an MFC program without its dlls... it won't work !

and i trust MSDN on this point !!

you can trust whom you want ...
I just told you my experience i ' ve copied my applications(simple exe-s,VC++ 6.0) to too many computers-s of my friends and not only who did not have Visual Studio installed and my app ran without any problems.
You can ask anybody that mfc42.dll is installed during the win98/xp install automatically.
Of course same did not work with app-s built on VC++.Net 2003

I agree. Point #2 is usually the reason that folks think MFC exists with native Windows.

I agree again. This has happened to me on more than one occasion.

i've searched for google to find out whether is mfc42.dll win native file and found this Here :

mfc42.dll (Microsoft Foundation Classes Library) - Details

The mfc42.dll library is required for windows to operate. It provides a number of classes and code functions that are used in a wide variety of programs written using the Visual C++ programming language. If mfc42.dll is unavailable, any software that relies on the functions that it provides will crash and/or become unstable.

Nope ! Only if you choose to statically link the MFC to your project. Otherwise you still need an external dll containing the MFC's.

That's what I have done in my most projects. Just wondering, if there is any reasons that should not be done, except an increase of overall application size.

Thanks

The main reason why this should not be done, is because MS will not be able to help you with updates if you statically link to their libs into your app.

Another good reason might be applicable when you develop a large application. The reason that comes to mind is: when you statically link to MFC's libraries, your link time will increase dramatically. This is not very pleasant if you have to wait a very long time before your application is linked together.

Use depends.exe to see what dll's your exe needs. That's the sure way. But i'd reccomend against shipping kernel32.dll etc Wink | ;-)

Run depends.exe and load your EXE. This is the best way to tell which DLL you need.

If i remember correctly you just make the executable file for your application in the release folder (ie release ) and not debug.It may solve the problem.If someone thinks that i am incorrect please give me a feedback.

nop, that's not it.

of course, when i compile the project, the exe file is located into the Debug or Release folder.
but if you read all the posts of the subject, i'd like to move the exe to a CD to be use on one's computer that is suspected not to have MFCxx.DLL on its system.

but it's ok now, i received many good answers to know what to do...

Once you have mapped a drive letter to a network resource, the functions that use said drive letter are none the wiser. For example:

FindFirstFile("c:\\*.*", ...);
FindFirstFile("n:\\*.*", ...);

operate in the same fashion.

Now if you are asking how to establish a connection between your computer and a remote computer, simply use NetUseAdd() or WNetAddConnection2().

Looking for Word/Excel Object model doc

Hi guys,

I am developing an app that will have an automated Excel object embedded. I am doing it by using typelib Wizard to include Excel Object Model classese and access its methods. As I am new to this, I was hoping to find some documentations about the classes. Unfortunately, I couldn't find any useful information for my own use, except the MSDN site which describes only some of the methods with VB and C# examples (no C++/MFC).

Does anyone know where I will be able to find more references to the Office Object Model?

Thanks alot~

Thanks alot Shog,

it does provide much more useful information for me Smile | :)

Further advancing to the topic, I start creating and formatting Excel sheet by following How to use MFC to automate Excel and create and format a new workbook[^] example. Most parts are very easy to follow except that I can't seem to find the OLE-specific CFont0 class as stated.

Adding #include "cfont0.h" to my main .cpp file

would just return

fatal error C1083: Cannot open include file: 'CFont0.h': No such file or directory

Any help would be great,
Thanks

Looks like something generated from one of typelib - if you've process all the Office typelibs, then it's prolly around somewhere (might have a different name though).
