Hello
Im building a client server application where the client will send information to the server using Visual C++ .NET. The communication and sending information to the server has succeed. I want to write the information that is retrieved by the server to Microsoft Access. How can i accomplish this? For your information, Im using the win32 console application as the C++ platform. Is there any sample code which i can refer to? A friend of mine told me that there is something to do with managed C++. I really dont know anything about managed C++. Is it the same with the normal C/C++ code? What are the difference? Sori due to my 'basic' questions. hehe. Kinda desperate currently. Anyway, thank you and your reply is really appreciated.

The openGL Red Book is a great resource to start learning about openGL: it is available online here[^].
PS: as far as I know, it is a legal on-line version. If you think it is not the case, please tell me and I will remove the link. This comes from the "About this guide" page:
This book is freely accessible on the Internet at http://arctic.eng.iastate.edu:88/SGI_Developer/OpenGL_PG/. However, it is presented in a format unsuitable for download and off-line browsing, since it is accessed and cross-referenced using cgi scripts. I manually downloaded and edited all the text and figures, removed most of the links in the text and reformatted the chapters into single files. None of this was made for profit or for the purpose of violating copyright - the book was online, and I just made it easier to use and download. All the original copyright still remains.

I add a bitmap to the resource, the bitmap is not as big as I expected.(likewise the bitmap is 100*60, but I just want it as 32*32). I know I can use a picture program to achieve this goal, but I just want to do it in the code.
And I'm not drawing the bitmap myself using CDC, but use it in the CPropertySheet, use a HBITMAP as parameter, so can I CBitmap::LoadImage load the original bitmap, and deal with it in the memory to transform it as a smaller one? then pass the HBITMAP handle to the parameter.
If you have some idea, plz give me some code sample, thx a lot.

Load Bitmap using LoadImage API. in 4th and 5th parameter pass dsired width and height. Pass HBITMAP returned by LoadImage in CBitmap.Attach() method and casll CBitmap.Detach() when work finish.

Where does the CDynamicAccessorEx class comes from ? Did you make sure that the cpp file of this file is part of your project ? A frequent error is also to declare a construtor and destructor but forget to give a body (and it seems that is your case, because only those two functions are missing).
Make sure you have a body for those (even if it is an empty one).

construtor and destructor have function body, CDynamicAccessorEx is part of project.

Can you post those functions here ?

Hi,
Have you provided the definition for all the class members ?

Use a keyboard and an IDE like Visual Studio. That's how we do it.

I appreciate your attitude toward encouraging people on the forum. But, the fact that the OP is a junior member has nothing to do with my reply. I would have given an even more discouraging reply if the OP was a senior member. Generally, a person posting a query on a message board is expected to read the guidelines and follow it. The same applies to this message board too. I wouldn't be discussing any further with you on this topic.
PS: Please try to avoid using SMS language as I believe that you have a full QWERTY keyboard.

This way you can write...
WSAEventSelect(listeningSocket, hEvent1, FD_READ | FD_WRITE | FD_CONNECT | FD_ACCEPT)
or loat of example on codeproject or codeguru.

Hi Firends,
I am using the fllowing code to create a meta file
HDC hDCMeta = CreateEnhMetaFile(m_hDC, "D:\Data.emf", NULL, buf);
m_hDc is handle to printer dc. buf represents the name of application.
after creating the meta file I am drawing some information with m_hDC and at the end closing the metafile.
m_hMeta = CloseEnhMetaFile( hDCMeta );
CloseEnhMetaFile() function fails as it returns NULL but when tring to get the error message using GetLastError its returning ERROR_SUCCESS.
Before calling CloseEnhMetaFile() I prompted a messagebox and checked that the file Data.emf created in D:\ drive with size more than 1 GB. (I am having 1 GB ram).
soon after CloseEnhMetaFile() call fails the file also get delete disk.
Please help.

How is this working with only a single backslash?

Hi friends,
I have unicode string like
wstring filename = "??????? ?????, ????? ? ª ????";
which I am trying to convert to normal multibyte string using
WideCharToMultiByte API.
But the conversion fails. Please refer Following code
int Length ;
// Here I call this API to get length of the wstring
char* output = new char[Length];
int foundUnmapable = FALSE;
My call is like
WideCharToMultiByte(CP_ACP,
NULL,
input.c_str(),
-1,
output,
len,
NULL,
&foundUnmapable );
This code fails saying that foundUnmapable = TRUE;
GetLastError() return 1008 error number which means
"An attempt was made to reference a token that does not exist."
Can anybody point out the issue here?

One correction
wstring filename = "??????? ?????, ????? ? ª ????";
Which is actually string of special characters. But I am unable to post those chars in this web page. It automatically gets converted to "????..."
