Yes sir,can u explain me in details

My project contain 5 dll and 4 dll are win32 and one dll is MFC shared dll.These dll are written in c language.our task is redesign project and convert these code in c++ language (means use object oriented concept).One main dll is IProfile that contains exported function and that exported function are called from another dll.In c language they are use extern.But in c++ i have to create wrapper class for that.But i dont know how to create wrapper class.can anyone please tell me how to create wrapper class in c++. Thanks in advance

i m creating win32 dll in vc++(mfc) application.i have to call dll function from another dll. But i dont no the way,how to calling dll function from another dll. Please help me. Thanks in advance.

below is my code.i m using CIPAddressCtrl contorl of vc++(mfc).problem is that we thia case statement is execatuted messagebox is dispaly twice.I wont understand .Plz anyone has idea about this help me to solve my problem.. void CServerIPAddress::OnIpnFieldchangedServerIpaddress(NMHDR *pNMHDR, LRESULT *pResult) { LPNMIPADDRESS pIPAddr = reinterpret_cast<LPNMIPADDRESS>(pNMHDR); *pResult = 0; int nFieldIndex = pIPAddr->iField; int nValue = pIPAddr->iValue; CString csValueFormat; switch(nFieldIndex) { case 0: { if(nValue < 1 || nValue > 223) { csValueFormat.Format(_T("%d Is not a valid entry."),nValue); csValueFormat.Append(_T("Please specify a value between 1 and 223")); AfxMessageBox(csValueFormat); } } break; default:break; } }

this drives me nuts... I have the following function that checks against an IP address control for displaying an error message box if users specify an invalid IP value that greater than 255 ON_NOTIFY(IPN_FIELDCHANGED, IDC_EDIT_LISTEN_ADDRESS, &CNetworkBindingDlg:SurprisenEditListenAddressChanged) void CNetworkBindingDlg:SurprisenEditListenAddressChanged(NMHDR* pNMHDR,LRESULT* pResult) { LPNMIPADDRESS pIPAddr = reinterpret_cast<LPNMIPADDRESS>(pNMHDR); if(pIPAddr->iValue > 255) { CStringW ErrMsg; ErrMsg.Format(ResourceString(IDS_INVALID_IP_ADDRESS),pIPAddr->iValue); MessageBox(ErrMsg,ResourceString(AFX_IDS_APP_TITLE), MB_ICONERROR); } } Somehow the MessageBox() function execute twice. I chased the code and noticed that the MessageBox() is executed the first time, but the message does not show up, but the execution control comes back to the CStringW ErrMsg line, the MessageBox() will be executed the second time. And then the message box dialog shows up twice. Any suggestion? thanks.
