Hi,
I have several applications that have to use a set of same constant values.
Those constant values are defined in several CPP files in the
following way:
const char* name = "text";
I want to compile those CPP files to some software component
(maybe lib or dll) in order to use it in runtime in my application.
I considered to build those CPP files to DLL and then to load it explicitly
(by LoadLibrary() and GetProcAddress()).
The problem is that this way requires redefinition of all the constants defined in
CPP files in my executable and I would like to avoid the redefinition.
Is there any other way to compile those CPP files to software component in a way that my
applications will load it in the run time and there will be no need to redefine the constants
and no need to compile or link my applications each time the CPP files are changed?
Thanks in advance,
Avi

A solution with configuration files is not good ? It is just a suggestion, maybe it's not adapted to your problem.

If you use GetProcAddress you don't need to include files. You just need to typedef the prototypes of the functions that you need to load.

Suppose in WSAAsyncSelect model.
Peer A send "1234" to peer B. Just when "12" is arrived at Peer B, the network is disconnected. Will peer B be notified with FD_READ and receive "12"? What is the case if the receiving buffer is just full after receiving "12"?

I think yes peer B be notified with FD_READ and receive "12"

Damn!! It has been unable to delete for 10 minutes!
Yes I deleted my posts. I close my IE, and re-start an IE instance, ... my posts get back!  Is this because of the redundancy server of CP ?

but then whole application gets closed.
How to do it efficiently?
Instead of that call AfxGetApp()->CloseAllDocuments();

Hi All,
I have succeeded in compiling a massive project, originally from vc6 to VS .Net 2005.
Now, while linking I am having loads of linker errors with the above code.
LNK20019 and LNK2001. Giving error msg that some symbol is not found. Actually, the library with the symbol has been already compiled as dll.
I looked into the documentation. The errors may be caused by
1. use of Inline functions (2019, also sometimes 2001)
2. use of C Runtime LIbraries (2001)
I dont know how to solve this problem. Can anybody tell me what should I do to remove these errors ?
I know all the missing symbols are there and the libraries are my own, so I can also change the code of the libraries.
this is the buildlog of one of the projects in the solution.
I also attach the implementation of a small class which is referenced and the symbol (destructor of that class) is not found and results in the error.
I hope this helps you guys to guide me.

Hi,
I have to work on a lightweight dial up application for connecting to our company servers. Is there any link which talks about this kind of applications? What does it mean by RAS dialing capability?

Thank you.. I will go through it. How to start working with dial up connection projects? Is dialup networking and dial up connection projects are one and the same? Can anybody shows me a link to study on the topic?

Use the following APIs
RasSetEntryProperties - to create a new connection in the RAS phonebook
RasDial - to dial
RasHangUp - to disconnect
RasGetConnectStatus - to get the status of the ras connection. Also use this after a RasHangUp to see when your handle is closed, ie when windows really is finished with your ras connection. You do that by polling RasGetConnectStatus until it returns ERROR_INVALID_HANDLE.
RasDeleteEntry - to delete a phonebook entry created with RasSetEntryProperties
Also note that the RAS Api is very much OS version dependant. You will see that when reading the docs for RasSetEntryProperties. I would recommend to go for minimum Win200 if you cant do that you will have much more work to do.
The following RAS properties that you can set in the GUI has no function to set them. So if you really need to change them you need to update the ras phonebook file manually
* Redial on link failure
* DNS Suffix
* MS client
* MS File printer sharing
* Hardware flow control
* Connection speed
Feel free to ask more questions if you like... Ive done a really heavy weight dialer

I am converting a project fom VC++6 to compile under Visual Studio 2005. I have sorted out everything except this line:-
HtmlHelp(this->m_hWnd, strRef, HH_DISPLAY_TOPIC, NULL);
This gives me the error:-
error C2660: 'CWnd::HtmlHelpA' : function does not take 4 arguments
I have Googled it and seen a solution suggesting replacing HtmlHelp with ::HtmlHelp, but this did not work, I then got a Linker error:-
error LNK2019: unresolved external symbol _HtmlHelpA@16 referenced in function ....
Any ideas?
Many Thanks,
Ali

this->m_hWnd can be left out.

Thanks for the suggestion, I tried:-
HtmlHelp(strRef, HH_DISPLAY_TOPIC, NULL);
But now the error is:-
error C2660: 'CWnd::HtmlHelpA' : function does not take 3 arguments
In fact it seems that HtmlHelp now takes 2 parameters, but I can not figure out what they should be!
The irony of it is that when I press F1 for context sensitive help on HtmlHelp, it says "Information Not Found".
So I can not get context sensitive help on my problem with context sensitive help!
Thanks again, any other suggestions?

exapmle from MSDN
HWND hwnd =

GetDesktopWindow(),

NULL) ;
::HtmlHelp(hwndhandle,file,HH_DISPLAY_TOPIC,15);

Hi, and thanks for the help.
I am sorry but I don't follow what you mean.
I have changed my line of code to:-
HtmlHelp(HH_DISPLAY_TOPIC, NULL);
And now it compiles and runs, but when I click the 'Help' button it does not work, it says 'Failed to Launch help".
I suppose it doesn't know what the name of the help file is? I guess I've got to do something else, but what?
Thanks for your help,
Ali

#include htmlhelp.h
you get error LNK2019 because you need to
import
htmlhelp.lib
i use this way and its work without error Failed
HWND hwnd = ::HtmlHelp(::GetDesktopWindow(),
"c:\\2.chm",HH_DISPLAY_TOPIC,NULL) ;
