Hi,
I need to use a CString object in my dll,so i've included <afx.h> file.
the problem is that i get this error:
Compiling...
TCPlib.cpp
c:\program files\microsoft visual studio\vc98\mfc\include\afxv_w32.h(14) : fatal error C1189: #error : WINDOWS.H already included. MFC apps must not #include <windows.h>
Error executing cl.exe.
when i don't include <afx.h> i don't get this error,but i can't use CString.
what should i do?
Regards,
Eli

1. Ensure thatm you're not including windows.h anywhere in you're dll
2. ensure you have a precompiled header - e.g. stdafx.h
3. add #include <afxwin.h> to stdafx.h
4. make sure you're project settings are set to include MFC

When you include a MFC header file you must not include windows.h.
MFC does include it!!
Furthermore you should better not use parts of MFC in an non-MFC application.
Don't try it, just do it!

Thanks for you prompt reply.
I need to make a regular dll with objects of MFC(i.e CString).
Which DLL workspace should i choose in the MSDEV?
regards,
Eli

If the program that will load the DLL might NOT be MFC, then choose MFC AppWizard (dll) as the project type. Then in Step 1 of the wizard, make sure you choose "Regular DLL with MFC statically linked". This will allow your DLL to use MFC but the parent application does not have to be an MFC program. Don't pass MFC objects between your DLL and your program, or you might experience memory issues and the created MFC objects are not necessarily from the same memory pools.

I have the same problem. But I can't solve it with these hints.
I've a COM-Client and Server. Both non-MFC. I can't find anywhere the windows.h.
|
|
|
|
|
If the problem is the 'windows.h' appearing in your files, is it possible both of you can try the include file dependency checker tool from CodeProject to see if that will help you locate it?

Hello
I would like to add multiline text in the MFCGrid ... Is it possible to do such things without changing anything to the original code ?
Thanks for your help

It already supports the display of multiline cells. You just have to clear the DT_SINGLELINE format.
pCell->SetFormat((pCell->GetFormat() & ~DT_SINGLELINE) | DT_WORDBREAK) Tooltips and in place editing need work though.

In my project I have, say, three string tables for
language packs - English, French and German.
After building all string tables(having same ID)
into the .exe file, how can I control which
string table the program should use during the runtime?
That is to say, if I want the outcome to be of English
interface, is there any way of coding to manipulate
the choice of the string table used?
Great thanks in advance for your reply

How can I change the tooltip of the restore button on the titlebar to display
"Full screen" instead of "Restore Down"?
|
|
|
|
|
Have a look at WM_NCHITTEST and WM_NCMOUSEMOVE. Maybe you can handle then in your own functions and create a tooltip yourself.
Don't try it, just do it!

hi,,
Anyone familiar with the AESalgorithm
There is an implementation of the AES algorithm in the below link. If u download it..
http://www.thecodeproject.com/cpp/aes.asp
in Table.h
(1.) Why have they used s boxes in ‘int’s? why not
const int CRijndael::SBox[256] rather than ---const char CRijndael::SBox[256] and replace the negative values with positive?
(2.) What does
const int CRijndael::sm_T1[256] …. const int CRijndael::sm_T8[256] tables correspond to?
(3.) and const int CRijndael::sm_U1[256]…const int CRijndael::sm_U4[256] tables correspond to
(4.) also const int CRijndael::sm_shifts[3][4][2] tables correspond to?
tnx

Why not pose these same questions to the article itself? That way the author has a chance to respond.

Dear Sir,
I have write a simple winsocket program on XP Pro SP2 with Visual studio net. 2003. All is fine.
But when running the program on other machine like XP Pro SP1 or Win2000 Pro SP4 or on XP Home edition, my program does not run due to ntdll.dll (function RtlIpv6StringToAddressExW does not exist in preview version of ntdll.dll)
And with the app dependency walker and can see the difference between those ntdll.dll.
I do not need to update my other system to XP Pro SP2; What can I else do.
Thank you in advanced.

It sounds like you are calling an API that was added in SP2. Your only choice is to not call it on pre-SP2 systems, and find/write some equivalent code to use on those systems.

Thank you for your reply,
But I have resolved the problem. I have link my app to the all DLL of windows and not to the DLL install on my OS. and running the program in other system, all is fine.
This mistake is from MS, because it cause program build on XP Pro SP2 can run in older version if you link only with the old version dll.
have it in mind.

I've never heard about that api "RtlIpv6StringToAddressExW", and even google doesn't know it.
Nevertheless, take care when using ip6, it is often not yet supported by windows.
Don't try it, just do it!

Dear Alex,
Thank you for your reply to my request:
In fact if you have the VC tools: "Dependency Walker", and if you have XP Pro SP2, if you open the ntdll.dll, you will see the following function that MS have added and that are not in version XP Pro SP2.
"RtlIpv4AddressToStringA RtlIpv4AddressToStringExA RtlIpv4AddressToStringExW RtlIpv4AddressToStringW RtlIpv4StringToAddressA RtlIpv4StringToAddressExA
RtlIpv4StringToAddressExW RtlIpv4StringToAddressW RtlIpv6AddressToStringA
RtlIpv6AddressToStringExA RtlIpv6AddressToStringExW RtlIpv6AddressToStringW
RtlIpv6StringToAddressA RtlIpv6StringToAddressExA RtlIpv6StringToAddressExW
RtlIpv6StringToAddressW.
So when I build my App, the linker use the ntdll.dll and call the function RtlIpv4AddressToStringW and RtlIpv6StringToAddressExW. and those function are not defined in the preview version of ntdll.dll. My version is: 5.1.2600.2180
The call to those function is made from WS2_32.dll (at version 5.1.2600.2180 to )that call it from ntdll.dll
never try but make it.

I am using VC++.net 2003 to access matlab with C API, I have to call a function which is programmed in C#. It looks like VC++.net doesn't like "ref" keyword.
>>>>>>>>>>>
r = ma.GetMatrix(matname, ref a); /// <--- source code from C#
<<<<<<<<<<<
"ref" works well in C#, but when I call this function ("GetMatrix") in managed C++, I got an compilation error:
>>>>>>>>>>>
"cannot covert parameter 2 from 'double __gc[,]' to 'double (__gc *) __gc[,]'
<<<<<<<<<<<
I am new to VSS.net, could anybody kindly help me if there is "ref" equivalent keyword in C++?
Many thanks!
