Christer STLPort-4.5 Michael Martin2-Oct-01 2:35 Michael Martin 2-Oct-01 2:35  I am wondering if anyone has installed STLPort-4.5 on their VC++ installation? I have downloaded it (after being introduced to it by Christian Graus) and read through the doco. If I want to use the iostream that comes with STLPort-4.5 I use installation method 1. If I don't want the iostream then I use method 2. I am wondering what I lose/gain by using the STLPort-4.5 versions?

Are you talking in general or specific to the 4.5 version ? I have been told by a friend who had installed it, that it is general a better version of STL implementation, and that it had a few extra's like hash_map and so on. As I recall I have also browsed the code and I remember thinking it was much more readable than the crap the comes with VC. Re: STLPort-4.5 Michael Martin2-Oct-01 3:59 Michael Martin 2-Oct-01 3:59  I think I am talking about the iostream stuff that comes with 4.5. Also if I will break anything else in VC++ if I install it. Michael Martin Pegasystems Pty Ltd Australia martm@pegasystems.com +61 413-004-018 "Don't belong. Never join. Think for yourself.

I don't even recommend GCC for compliance -- it fails for me on bitset operations.) From what's been posted on the site, I hear the Dinkumware upgrade is better with VC, but I can't attest to this -- I got BCB for less than Dinkumware's STL upgrade.

Multiprocessor resources/Realtime Stan the man2-Oct-01 2:05 Stan the man 2-Oct-01 2:05  Hi. I was wondering if there are any sites or resources that talk about multiprocessor programming or has code snippets etc for this. With this, you should be able to get very close to semi hard realtime I am assuming. Does anyone also have any ideas of where to find any clues about writing somesort of driver or something that can constantly do lets say data acquisition and such at a hard realtime rate while the GUI works when it can? Thanks Just a question on WININET Chaos Lawful2-Oct-01 2:05 Chaos Lawful 2-Oct-01 2:05  Here is a function: void Foo(CFtpConnection *pFtpConnection) { CFtpFileFind finder(pFtpConnection); CString currentDir; BOOL bFlag=FALSE; bFlag=finder.FindFile(NULL); pFtpConnection->GetCurrentDirectory(currentDir); while(bFlag) { bFlag=finder.FindNextFile(); if(!finder.IsDots()) { pFtpConnection->SetCurrentDirectory(finder.GetFileName()); pFtpConnection->SetCurrentDirectory(currentDir); } } finder.Close(); } When I call this function with a valid CFtpConnection object's address, will it generate some errors? If so, could you explain something to me? Law is meaningless without chaos. Chaos without Law is equal to destruction. Chaos and Law create our rich and colorful world. Getting rid of the title bar Stan the man2-Oct-01 1:58 Stan the man 2-Oct-01 1:58  HI. I have done everything I know of to try to get rid of the blasted title bar in a CFrameWnd derived Frame with CFormView views. I would think that if you get rid of the WS_CAPTION in the Precreatewindow that should do the job but nope. I also got rid of the MENU OK in there by setting it to NULL. Any clues? Re: Getting rid of the title bar 2-Oct-01 8:21 2-Oct-01 8:21  In the mainframes OnCreate() function : ModifyStyle(WS_CAPTION,0,SWP_FRAMECHANGED); // removes title bar ModifyStyle(0,WS_CAPTION,SWP_FRAMECHANGED); // brings it back CListCtrl Refreshing AJ1232-Oct-01 0:54 AJ123 2-Oct-01 0:54  Hi, I have a CListCtrl, which doesn't seem to refresh properly. All is well until i call a dll which opens a window, when the window is moved over the CListCtrl it refreshes fine. But if the window is closed whilst covering the Clistctrl the covered region doesn't refresh. But all other controls seem to refresh fine under these circumstances Cheers Richard Re: CListCtrl Refreshing Tommy H D Svensson8-Nov-01 23:06 Tommy H D Svensson 8-Nov-01 23:06  Hi, Did you come up with a solution to this problem cause I have reached the exact same situation? /Tommy serialization 2-Oct-01 0:51 2-Oct-01 0:51  I have declared the class CMyDoc like this : "class CMyDoc : public COleServerDoc, public CMyClass" Definition of class CMyClass : "class CMyClass { protected : double mAge; COtherClass mOtherClass; //(not derived from a CObject class) }" the serialization of members like mAge works correctly, but when I want serialize class members like mOtherClass, the compiler send me the following error : "error C2678: binary '<<' : no operator defined which takes a left-hand operand of type 'class CArchive' (or there is no acceptable conversion)". How can serialize such members, must I make the class COtherClass serializable ? thank in advance for your help. Fred. Fred Re: serialization Tomasz Sowinski2-Oct-01 1:28 Tomasz Sowinski 2-Oct-01 1:28  You have two options: 1) create an operator<< which accepts a reference to COtherClass as 2nd parameter 2) 'manually' serialize data members of COtherClass in CYourClass::Serialize. In this solution, CYourClass needs an access to COtherClass members, directly or through accessor/mutator methods. Tomasz Sowinski -- http://www.shooltz.com Re: serialization 2-Oct-01 3:12 2-Oct-01 3:12  Thank for your fast response, but can you be more explicit in your soluces. I have joined here fragments of my aplication : //class CMyDoc : void CMyDoc::Serialize(CArchive& ar) { COleServerDoc::Serialize(ar); if (ar.IsStoring()){ ar << mAge; ar << mOtherClass; }else{ ar >> mAge; ar >> mOtherClass; } } //********************************************************* class CMyClass //**** operator << **** ostream& operator << (ostream &os, CMyClass &pClassTest ) { os << "Classe " << pClassTest.mAge << endl < Updating property pages 2-Oct-01 0:49 2-Oct-01 0:49  I have a property sheet with several pages present in it. On one of the pages, it is necessary to update another 2 pages if I make a certain change, to have it reflected on the other pages if I tab to them. This seemed like a candidate for a user defined message to all the pages of the sheet, so each page could either notice or ignore the action and take whatever action is required. My first attempt was in the propertypage code, a new message handler #define UWM_NEWROWCOL (WM_USER + 1) ON_MESSAGE(UWM_NEWROWCOL, OnNewRowCol) implementation LRESULT CDragDataPage::OnNewRowCol(WPARAM wparm, LPARAM lparm) { TRACE("Drag New Row/Col %d %d\n", wparm, lparm); return 1; } then to send the message I've tried: CWnd *parent = GetParent(); // parent of the propertypage is the propertysheet?? parent->PostMessage(UWM_NEWROWCOL, UWM_NEWROW, cell.row); and parent->SendMessageToDescendants(UWM_NEWROWCOL, UWM_NEWROW, cell.row, TRUE, TRUE); The 2nd version occasionally succeeds, in calling the handler for the page its being sent from (but not always), but not usually for the other pages of the sheet with similar registered handlers. If I set a breakpoint on the SendMessageToDescendants it sometimes works, but it pretty random. I'm sure I'm doing something stupid here. Question is what Julian. Re: Updating property pages Tomasz Sowinski2-Oct-01 1:25 Tomasz Sowinski 2-Oct-01 1:25  Other property pages may have not been fully constructed when you send the message. By default, property sheet creates a window (HWND) when you activate given page. If you want to create all HWNDs for property pages during initialization, use PSP_PREMATURE flag. Tomasz Sowinski -- http://www.shooltz.com Re: Updating property pages 2-Oct-01 21:37 2-Oct-01 21:37  Brilliant - thats what the problem was. Many thanks!!! Julian. WebBrowser alternatives? 1-Oct-01 23:24 1-Oct-01 23:24  Hi, I'm developing an application and I would like it to utilise a WebBrowser control. I would like to control the scroll bars and border styles programatically, only the Microsoft control does not appear to allow access to these properties. Are there any alternative controls out there? Matthew stack overflow 1-Oct-01 23:05 1-Oct-01 23:05  Hello everybody, I have a big problem. I can't execute an executable file in witch i call class import from two dll. When i launch my exe the error: 0xC000000FD:Stack overflow appear. What can i did for such a problem? Thanks for help. Re: stack overflow Tomasz Sowinski2-Oct-01 0:08 Tomasz Sowinski 2-Oct-01 0:08  Stack overflow usually means that you have infinite recursion in your program. Have a look at Call Stack debug window when your program crashes - you'll see where's the problem. Tomasz Sowinski -- http://www.shooltz.com Re: stack overflow 2-Oct-01 0:12 2-Oct-01 0:12  I found how to avoid this. But i know now how to increase the stack size with /STACK in link menu. A question about CFtpConnection Chaos Lawful1-Oct-01 22:34 Chaos Lawful 1-Oct-01 22:34  Does SetCurrentDirectory() in CFtpConnection throw any exceptions? Law is meaningless without chaos. Chaos without Law is equal to destruction. Chaos and Law create our rich and colorful world. Re: A question about CFtpConnection Michael P Butler1-Oct-01 23:01 Michael P Butler 1-Oct-01 23:01  The docs say Returns Nonzero if successful; otherwise 0. If the call fails, the Win32 function GetLastError may be called to determine the cause of the error. Looking through the FTP code, there doesn't seem to be any code to throw an exception. Michael
