I want to build executable with shared MFC dlls to reduce the final size.
But VS7 link my exe file with shared mfc70.dll which is not available on default win98.
So I think I need to link my exe against mfc42.dll which is available on most systems.
What I should gonna do?

The usual thing to do is distribute the DLL along with your program. It's simple to do if you're packing everything into an intallation executable.

Thank you. But in my situation the final size is critical. The aplication is just a some free add-on to some other application. So all should be kept in one executable and size should be no more then 100kB.

Both mfc42.dll and mfc70.dll are redistributable files there is no garantee that either one already exist on the users machine. Therefore, even if you link with mfc42.dll you still need to include it in the install. If you do not want to include the MFC DLL in your installs then you should not be using MFC.
Trust in the code Luke. Yea right!

Thank you for your reply, but i have another question: how can i get the Sql Server Name that run on the server?
|
|
|
|
|
Do you mean the name of the Windows NT server that SQL Server is running on? How about GetComputerName[Ex]?
|
|
|
|
|
I mean I want to let my computer search SQL Server's computer name and SQL Server name and list them, but i don't hnow how to do it.
|
|
|
|
|
Try the sp_server_info stored procedure.

I've just got the special upgrade from version 2002 to version 2003.
1.) Is that possible to install the 2003 over 2002's directory, so that
I will not have two Visual Studio.Net? When I installed it, it asked me
where do I want to install, I installed it in a new directory. So I ended
up with VS.Net 2002 and 2003 coexist. If I install the 2003 in the same
directory where 2002 is, does that mean it will overwrite the 2002, so
it will end up just 2003? (I don't need 2002 anymore) Which one do you
recommand? How did you do it?
2.) Once I installed the upgrade, I found that the new feature in VC++
allows you to hide and show code(the + and - sign) very annoying. Is
there a way to disable it?

I recommend installing Visual Studio .NET 2003 in its default directory. That will allow you to have multiple versions of developer studio. Now, if you wanted to use the 2003 version only, then I highly recommend that you uninstall the older version before installing 2003.

Concerning the second question. The oulining (the + and -)is availabe in version 2002 as well but it's not enabled by default.
To control this in 2002 you should go to Tools|Options then in the options dialog go to Text Editor->C/C++->Formatting and check or uncheck the Outlining option.
I dont know if there is a difference between the options dialog in 2002 and 2003 but I hope this could help.

I'm working on a project and I'm including sockets. I've included <winsock.h> but when I try to use the socket() function, it says "unresolved external symbol _socket@12" Anybody know why it does this and/or how to fix it?
Thanks

Hi.
I am wondering about advantages and disadvantages for the following:
1. Making one DLL that hold MANY things. Or many smaller DLLs that hold only things useful for specific purposes (like graphing stuff, database stuff).
2. What happens when a DLL needs to call fucntions from another DLL and at the same time the main program will also need that other DLL. Will the system automatically load it only once etc? I am not too familiar with how this done but just want to confirm.
3. Is there an easy way to keep track of projects (specifically headers in the DLL projects etc) so that when a file is updated, it will automatically update. I do not want to add the header file to every porject file folder and try to keep track of everything like that. Knowing myself, I will definitely screw up somewhere along the way. Any ideas?
Thank you in advance!

1.Logically it's better to separate them based on tasks.
2.the OS manges this for you .. it loads the DLL and unloads it when no application needs it.
3.why don't try Visual source safe ? (Even if I don't like it myself  )

I have in mind to write an application that I'd eventually like to distribute. It is essentially a work out and diet data tracker. I know that there's dozens of these out there, but mine will be the best one yet (heh, heh...).
Ok that notwithstanding ... it seems obvious to me that the best way to store the data is in a database. However ... once I've created the application, how do I go about distributing it without requiring that the user have MS Access, or some other database software installed.
Is there some kind of lightweight solution I can use that I can access using ODBC and distribute with my application? Is it possible to just wrap up the necessary Access .dll's and distribute those with my app? (Licensing issues aside)
Thanks in advance for any advice.

The Jet database engine (which is the guts of Access) is free to distribute (in fact it's preinstalled on XP - possibly 2000 as well). Alternatively you could go for something like MySQL.
