Appologies for not posting this on VC++ message board ( the link was timing out) I am trying to call a DLL written in Fortran from my VC++ application. Everything works fine, but when the Fortran DLL runs into trouble (some exception occurs in the FOrtran DLL) I see a dangerous looking Dialog Box, given the stack trace and the VC application simply exits. I have tried enclosing Fortran DLL function call with both try-catch and __try__except blocks, but the code in the catch/except never gets executed. Is there any way to catch Exceptions raised in FOrtran DLL in the calling VC++ applications. Any help will be greatly appreciated. cheers, kashif manzoor peace to all

Rafi, This error occurs for two reasons: (1) if you are sacing the file differently than loading it e.g.: if (ar.IsStoring()) { // storing code ar << someVariable; } else { // loading code, is trying to read a variable that was not saved. // So obviously you are trying to read past the file and ar >> someVariable>>anotherVariable; } (2) if you are readin/loading a file that was saved by some other program then there is a strong chance that such an error will occurr (again this is related to reason (1) (3) If you save the data using Serialize(&ar), and load/read the data using ar>> operator then you will again get the mentioned error. I think your problem is related to category (1). Make sure you are reading exactly the same (and also in the same order) that you wrote. Normally I simply copy the saving code in the loading block and simply change the << to >>, to avoid any mistake. -cheers, kashif manzoor peace to all

Your teacher wants you to read two topics: (1) operator overloading (2) polymorphism Although I personally can give you a complete answer to your question (as I have given similar question to my students) but I believe that if you simply read the above mentioned topics you would be able to solve the problem yourself. Basically the "Stock" object has an implementation of "<<" operator that outputs the conctenated string containing the attributes of Stock object The "Stocks" object will have its own "<<" which uses the "<<" of Stock to produce a consolidated string that shows the details of ALL the stocks. You have already noticed that the return from with in the loop will give you an error. Since you for () condition is not properly shown (due to HTML format) i can't really see why u are returning from with in the loop - because this way your loop will only run once (but i guess u already know this). -cheers, kashif manzoor peace to all

I sort of lost you in the last paragraph where you have defined your problem. Are you trying to call a message handler function through direct function call ? If this being the problem then rather than calling the function directly - you must use PostMessage() (see MSDN help on PostMessage() ) to invoke the event handler. PostMessage() a parameter that contains the MESSAGE_ID, LPARAM, and WPARAM If i incorrectly understood the problem then can you please elaborate it further -cheers -kashif manzoor peace to all

To send a message use // see help of PostMessage for parameter options #define WM_GENNIE_LEARN_MODE 2000 // use any id as you desire PostMessage(WM_GENNIE_LEARN_MODE); Now in the message map of the class where you want the message to be captured (namely the parent class in your case) make an entry in the BEGIN_MESSAGE_MAP section as given below IMPLEMENT_DYNCREATE(..., ...) BEGIN_MESSAGE_MAP(... , ...) //{{AFX_MSG_MAP(CDict1View) ON_MESSAGE(WM_GENNIE_LEARN_MODE,OnGennieLearnMode) //}}AFX_MSG_MAP END_MESSAGE_MAP() Now declare the handler function, as given below //{{AFX_MSG(CDict1View) afx_msg LRESULT OnGennieLearnMode(WPARAM wParam, LPARAM lParam); //}}AFX_MSG DECLARE_MESSAGE_MAP() and define it as LRESULT YourParentClassName::OnGennieLearnMode(WPARAM wParam, LPARAM lParam) { // blah blah blah ... return ...; } /**********************/ The above code will send a message WM_GENNIE_LEARN_MODE to the parent window where it would be handled by the function OnGennieLearnMode(). In your case you would sen the DBLCLICK message, and handle it in your own handler function. hope it helps, -cheers -kashif manzoor peace to all

thanx for the clarification, -cheers kashif peace to all

include "stdafx.h" before including anything else i.e. move #include "stdafx.h" statement to the top and you won't get the error message -cheers -kashif manzoor peace to all

Assuming that you have already overridden the OnClose() method (WM_CLOSE message) and want to hide the application again here's what you should do. /* get the handle of the application and simply hide through the code similar to the pne given below. Since your application icon already exists in the taskbar you need not put it there again. Simply hiding the main window should do the trick*/ ::ShowWindow(GetParent()->GetSafeHwnd(), SW_HIDE); hope it helps, -kashif manzoor peace to all

Can u explain as to which one of them is your problem : (1) How to catch the CLOSE message, so that you can properly override it according to your needs? or (2) You have already overriden the close function and want to know how to minimize the application to the taskbar again ? -kashif peace to all

In case there's no cross-over ethernet cable available you could fall back on a bus network. just keep two terminators handy peace !!!!

One solution could be to use Bitmapped buttons. Explore CBitmapButton, CBitmapButton.AutoLoad() and other related functions. Basically uyou would first create a Bitmap to be put on the button. Now create the button on your dialog box, using VC++ Visual Editor - check the "Owner Draw" and "Bitmap" options for the button. In Caption give the same name as the name of the bitmap. If the bitmap was named "FIND" then your button caption should read FIND. Give the ID for the button e.g. ID_FIND. Now before displaying the Dialog declare a member variable CBitMapButton find; find.AutoLoad(ID_FIND, this); I am telling you thus from the top of my head, so the information should be treated as a pointer to the right direction and not as an absolute solution :) Software Engineer (Techlogix (pvt)ltd) Visiting Faculty Informatics, Lahore

Kuniva, Please see the attached sample code of a Winsock client. With a little bit of improvisation and MFC socket programming knowledge you could easily change it to your needs. /***************************************/ /* This is the sample code for a client that send and receives some data from a server.*/ DownloadFileFromInternet(CString strAddress) { char buff[1024]; int s; struct sockaddr_in a; struct hostent *h; WSADATA wsaData; int SERVER_PORT = 1223;// The server port to which the client will connect. // This call initializes the Winsock.dll WSAStartup(0x101, &wsaData); // Initializing the sockaddr_in datastructer with all zeroes. memset(&a,0,sizeof(a)); // First assume an Internet dotted form address e.g. 198.168.0.1 a.sin_family = AF_INET; a.sin_port = htons(SERVER_PORT); // Connect to the server port a.sin_addr.s_addr = inet_addr("127.0.0.1"); // Connect to the localhost.

Another possible (brute force) method could be to OverLoad OnClose function (the message WM_CLOSE) in CMainFrame class. void CMainFrame::OnClose() { // Call the default implementation if you want the close functionality if (close_allowed) { CMDIFrameWnd::OnClose(); } // else do nothing } Software Engineer (Techlogix (pvt)ltd) Visiting Faculty Informatics, Lahore
