file locking problem... l a u r e n9-Oct-01 20:31 l a u r e n 9-Oct-01 20:31  hey anybody got any ideas as to why the following should be the case: on a windows nt ws machine with a windows nt svr we use a simple server side file lock to prevent multiple accesses to the same data on the server (ie, the ws checks for a locked file before accessing data on the server) ... this works fine same scenario but with a win2k client the file lock doesn't seem to show up puzzled me and i wondered if anyone a) knows what i'm on about and b) has a clue as to why it should be so --- "every year we invent better idiot proof systems and every year they invent better idiots ... and the linux zealots still aren't being sterilized" Winsock2 Speed Problem ColinDavies9-Oct-01 18:16 ColinDavies 9-Oct-01 18:16  Anyone got any ideas on how else to boost by internet speed (DL and UL) Currently I'm altering IPMTU and MSS FIFO Modem buffer TCP Recieve Window Size, And NDICache (although I don't even know what it does) Anything else I should be trying, I welcome any ideas Regardz Colin J Davies SetWindowText Jimolo9-Oct-01 17:17 Jimolo 9-Oct-01 17:17  hi all, in my project, i have a long procedure to run (around 1sec). i want to display a kind of status on screen when this procedure running. i found some problem. in my code, CABC::OnButton1 { this->SetWindowText("start"); // display in window caption m_edit->SetWindowText("start"); // display in a editbox LongProcedure(); this->SetWindowText("finish"); // display in window caption m_edit->SetWindowText("finish"); // display in a editbox } the result is that, only window caption display "start" and "finish" accordingly. the editbox can only able to display "finish" after the longprocedure(). seems to me that, the editbox only update after the finished the OnButton1 procedure... does anyone know how to display "start" in editbox, start the longprocedure(), and display "finish" in editbox after long procedure() accordingly? regards, Jim Re: SetWindowText 9-Oct-01 18:54 9-Oct-01 18:54  Try calling m_edit->UpdateWindow () immediately after the call to m_edit->SetWindowText ("Start"); How to share handle in dll among the process ? 9-Oct-01 16:42 9-Oct-01 16:42  +----------+ +----------+ | Process1 | | Process2 | +----------+ +----------+ | | | | +----|----------------|-----+ | | (Shared) DLL | | | V V | | Func1 Func2 | | | | | | +-V-----------+ | | | | HANDLE hVxD |<---+ | | +-------------+ | +-------|-------------------+ | V <----- hVxd = CreateFile(...) +-------+ | VXD | +-------+ Question> How to share 'hVxD' between 'Process1' and 'Process2' ?

I think it is the 4.7 Can somebody send it to me ? thanks, Stephane Re: seeking the BCGControlBar 4.7 Paul Selormey9-Oct-01 15:40 Paul Selormey 9-Oct-01 15:40  I think the last free version was 4.75. I should have it somewhere on my disk, but do not know exactly where. However, I could easily fetch 4.73/4.74 for you. You may however use the 5 series for the cool new features, and be supported too. Best regards, Paul.

Editbox Validation when hitting enter Steve The Plant9-Oct-01 10:34 Steve The Plant 9-Oct-01 10:34  Hi! How do I make an edit box only validate it's contents when hitting the enter key? The edit box is attached to a variable, and I only want the variable to get updated when I hit enter. Something that's not necessary, but a "nice to have" would be doing the same thing for the tab key. Besides doing the validation, it would also tab over to the next control. Steve Re: Editbox Validation when hitting enter Carlos Antollini9-Oct-01 11:18 Carlos Antollini 9-Oct-01 11:18  You need to use the OnKeyDown. When you detect the Enter, you can validate the Edit. Cheers!!! Carlos Antollini. Re: Editbox Validation when hitting enter 9-Oct-01 18:51 9-Oct-01 18:51  The usual way of doing this is to handle validation in the OnKillFocus method call for that object. Then, hitting Enter (which will submit the dialog if the edit control is on a dialog) or hitting Tab (which will go to the next field in the tab order if if the edit control is on a dialog) will both kick-off that event. If you're rolling your own interface in a non-dialog setting, you should be subclassing the parent window to pre process all the messages that come through your main window proc, and that would be where you would do Enter and Tab key handling (and other key for that matter). Event Notification in C++ Sam C9-Oct-01 9:34 Sam C 9-Oct-01 9:34  Does anyone know of a technique to "raise events" between two class objects? For example I have class A and Class B, I make a change to one of the member variables in class B, could be 20 of them, how do I notify class A of the change so it can see what has changed and act accordingly? Sort of of like Windows WinProc? Here are some simplistic ideas I have come up with 1. Create a system timer within class A and have it poll a "isDirty" variable in B and that is when it knows something is amiss. 2. Create a message queue in class A that B would send things too, and when A has a chance respond to the message. 3. Give up C++ programming and go back to Visual Basic (Not that I can do what I need to do within VB) I don't prefer C because that might weigh heavily on system performance, and 2 seems more complex than it should, and I am definitely trying to avoid 3 ! So if any C++ gurus can give me a hint or point me in the right direction I would be mighty appreciative of yous. <g> Sam C ---- Systems Manager Hospitality Marketing Associates Re: Event Notification in C++ Nemanja Trifunovic9-Oct-01 9:42 Nemanja Trifunovic 9-Oct-01 9:42  Don't use the timer for such thing. It is bad . Take a look at the "Observer" design pattern (I think there is an article on it on CodeProject). This is the way to go. Basically, you subscribe objects ("event sinks") to an object that raises events. I vote pro drink Re: Event Notification in C++ Sam C9-Oct-01 9:45 Sam C 9-Oct-01 9:45  Dang that was a fast response I can see not many people want me to go with option 3 either <g> Let me take a look at the observer design pattern. Thanks again for the quick response. Sam C ---- Systems Manager Hospitality Marketing Associates Re: Event Notification in C++ J Patel9-Oct-01 9:43 J Patel 9-Oct-01 9:43  You can use the Subject, Observer pattern. HTH Jignesh Re: Event Notification in C++ Sam C9-Oct-01 9:46 Sam C 9-Oct-01 9:46  Thanks for the respone and the URL I'll take a look at it, and thanks for helping me avoid option 3!
