Attaching Dialogs to Single Document Applications Caoimh31-Jan-04 6:59 Caoimh 31-Jan-04 6:59  I need to attach a dialog to a single document application. On the menu bar I want to go to view then 'Device Setup'. Once I click on the 'Device Setup' a Dialog should appear initialised with default values. How would I do this. Suggestions are much appreciated Re: Attaching Dialogs to Single Document Applications Mukkie31-Jan-04 9:11 Mukkie 31-Jan-04 9:11  Hello! Create new entry in resource editor in menu. By using class wizard create a method which will be called when menu item will be chosen. In this method instantiate dialog class instance, and call DoModal() Regions, randomizing images Worthi31-Jan-04 6:01 Worthi 31-Jan-04 6:01  I am currently a student at uni and need to randomize where a set of nine graphics appear along a graphic. These have hotspots allocated to them, and are stored in a seperate file. Is it possible to use regions to offset the images, or am I bartking up the wrong tree? I can offset the region to change where the hotspot is "located" but the original image needs to be offset aswell.

This class has two functions and a member variable CFile m_file First is StartLog conains code m_file.Open(.....); Second StopLog contanis code m_file.Close(); And also there is a function AddEvent like this: m_file.Write(.....); m_file.Flush(); I call StartLog when my program starts, and StopLog when it exits. AddEvent is called several times while program runs; It works fine mostly, but there is a problem: File gets corrupted (it contains junk) when the program gets terminated incorrectly. For example when somebody has rebooted computer or terminates it via task manger. (Close() is not get called in this case) Should I reopen and close file every time I need to write to it to ensure safety of the data??? Re: Strange file corruption valikac31-Jan-04 6:29 valikac 31-Jan-04 6:29  Yes. Add code in the class destructor to close the file. Kuphryn Re: Strange file corruption Artem Moroz31-Jan-04 6:50 Artem Moroz 31-Jan-04 6:50  I already did. The problem Is that when the program is terminated incorrectly, the garbage appears inside a file sometimes.... You see, the Close() is not called in such a case Re: Strange file corruption valikac31-Jan-04 13:06 valikac 31-Jan-04 13:06  Yeah. The only solution is to analyze the file as the program opens it. Do CRC check or simply calculate the bytes and remove all extra data.

If you manually open the file in append mode, write to the file, and then manually close it every time then you are unlikely to experience the corruption you are talking about. The only way it could get corrupted is if the system were incorrectly shut down during the few milliseconds that the file were open. Have you answered an MTQ? Check out the stats!

I'm using VC6 & STL in my program along with Openssl. I'm getting compilation error in OpenSSL\bn.h The error is as follows:- error C2955: 'modulus' : use of class template requires template argument list c:\program files\microsoft visual studio\vc98\include\functional(57) : see declaration of 'modulus' There seems to be some kind of conflict in template names, because STL and OpenSSL structure are using same template name. Is there any simple workaround for this ? Any help is appreciated. Cheers, Sheetal. Re: error C2955...error in template resolution Joaquín M López Muñoz31-Jan-04 7:14 Joaquín M López Muñoz 31-Jan-04 7:14  Have you inserted using namespace std; before including "bn.h"? If so, try deleting the using directive. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo CListCtrl Scrollbar Konrad Windszus31-Jan-04 3:46 Konrad Windszus 31-Jan-04 3:46  How do I always show the vertical scrollbar in an CListCtrl (report view)? Just call ShowScrollBar( SB_VERT, true ); in every OnSize method doesn't work, because then the last column (which has the flag LVSCW_AUTOSIZE_USEHEADER) is too big. The implementation of the CListCtrl seems to be really clumsy, because it is somehow handled completely different than in any other WIN32-Control. Thanks for any answer. Konrad Re: CListCtrl Scrollbar JussiL4-Feb-04 21:59 JussiL 4-Feb-04 21:59  Hi, I'm trying to solve the very same problem and I haven't been successfull with that ShowScrollbar-function either.. It doesn't help that I'm not that experienced with MFC. I'm wondering that could this be solved by simply using the WS_VSCROLL style when creating the control? Well, in my app the scrollbar _does_ show in certain situations when using that style (even if there are only few items in the report view and therefore no actual need for the scrollbar) but I haven't been able to pinpoint the exact conditions for this. My guess is that this behavior has something to do with redrawing.. You tell me But hey, give it a try and let the world know if it works.. -Jussi LINK : fatal error LNK1181: --> How to overcome this Anonymous31-Jan-04 1:50 Anonymous 31-Jan-04 1:50  How to overcome this error following error LINK : fatal error LNK1181: cannot open input file "..\..\..\..\Program Files\Microsoft Visual Studio\VC98\Lib\WINMM.LIB" What can be the reason for this?

Just set the correct path in Visual Studio. If you use version 2003 go to Tool->Options->Projects->Vc++ Directories and set the correct path for library files. In Visual Studio 6 it should be very similar.
