Have you heard about ADODb, OleDB, ODBC? If not then try to figure out what do you want to use and why. After finding a solution to this you can go and drill down to the basics and intricacies of the method you choose to use.
I now know what your database password is

Hi EveryOne,
In ActivexDLL I have written a method called Connect(..)inside a class. The method exposes the functionality of connecting to another system using sockets.
The problem here is when I compile my project I am getting link errors(unresolved external symbol). These errors are thrown when winsocks methods are called like htos(),inet_addr(),connect() are called.
Unresolved symbol (upto my knowledge) are thrown when the function definition is unknown or its different from the one that is implemented. since I am using an inbuild function (used the header file winsock2.h) what might be the cause to the problem? How would I Overcome it. Please find the code below.
STDMETHODIMP CRAPClientX::Connect(BSTR serverIP, BSTR serverPort,BSTR *output)<br />
{<br />
<br />
<br />
WSADATA wsaData;<br />
char returnString[150];<br />
<br />
int iResult = WSAStartup(MAKEWORD(2,2), &wsaData);<br />
if (iResult != NO_ERROR)<br />
printf("Error at WSAStartup()\n");<br />
<br />
<br />
SOCKET ConnectSocket;<br />
<br />
ConnectSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);<br />
<br />
if (ConnectSocket == INVALID_SOCKET) <br />
{<br />
sprintf(returnString,"Error at socket(): %ld\n", WSAGetLastError()); <br />
*output=SysAllocString(_bstr_t(returnString)); <br />
WSACleanup();<br />
return S_OK;<br />
}<br />
<br />
<br />
sockaddr_in clientService; <br />
<br />
clientService.sin_family = AF_INET;<br />
<br />
clientService.sin_addr.s_addr = inet_addr("127.0.0.1" );<br />
<br />
clientService.sin_port = htons( 27015 );<br />
<br />
<br />
if ( connect(ConnectSocket, (SOCKADDR*) &clientService, sizeof(clientService) ) == SOCKET_ERROR) <br />
{<br />
sprintf( returnString,"Failed to connect.\n" );<br />
*output=SysAllocString(_bstr_t(returnString));<br />
WSACleanup();<br />
return S_OK;<br />
}<br />
<br />
sprintf(returnString,"Connected to server.\n");<br />
*output=SysAllocString(_bstr_t(returnString)); <br />
WSACleanup();<br />
return S_OK;<br />
}<br />
kinldy reply.

Not linking to the lib file in which these functions are defined might be one cause . So, did you link your project to ws2_32.lib ?

Once I posted this question, I got the question which u asked; in my mind and then included the library (which I missed out earlier  )WS2_32.LIB. So I fixed it in the time you answered the question. sorry for wasting your time Cedric and thanks for the reply.

MSDN[^] should help you if nobody does and sometimes nothing helps. Not even MSDN .

Windows Forms Application is a CLR project - that means it's managed/.NET.
Use the appropriate DLL project - If you're using MFC, make an MFC DLL.
If using just Win32 in your DLL, make a Win32 console project and add the
appropriate Windows DLL code. etc....

It depends on what your DLL exposes as an interface. If your DLL has
managed interfaces it's easy. Unmanaged may require some kind of interop
from the managed code.

I don't think so, but in general it's not a problem: simply conjure up one in the target process from the HWND in question (HWNDs can be shared between processes).

I haven't tried it but isn't CListCtrl::SetBkImage good enough? Have you tried this?

You can test with follow code lines:
if (!m_wndToolBar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP
| CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) ||
!m_wndToolBar.LoadToolBar(IDR_TOOLBAR))
{
TRACE0("Failed to create toolbar\n");
return -1; // fail to create
}
//m_ImgList is a variable type CImageList
m_ImgList.Create(32, 32, ILC_COLOR32, 0, 10); //ILC_COLOR32 specifies the high color of 32 bits
m_ImgList.Add(AfxGetApp()->LoadIcon(IDI_ICON1));
m_ImgList.Add(AfxGetApp()->LoadIcon(IDI_ICON2));
m_ImgList.Add(AfxGetApp()->LoadIcon(IDI_ICON3));
CToolBarCtrl& tbCtrl = m_wndFormatBar.GetToolBarCtrl();
tbCtrl.SetImageList(&m_ImageList);

Can anyone help me on how to create log file in Visual C++ with MFC???
|
|
|
|
|
log files are just simple text files unless you want to create complicated ones. I usually enter the date/time at the beginning of the log entry and then the file name, function name and the Log message. You can use normal fstream objects to write to the file. The log function should open the log file, write the log entry then close it again.
In case you are looking for something complicated try to create a service for logging messages to a log file.
