(What message/event?) Led25-Jan-04 22:17 Led 25-Jan-04 22:17  How to detect a new device was installed ? (What message/event?) Basicly I've got an app that uses webcam(s). When they unplug, I get a nice event that the device is unplugged. But how can I detect that a (usb) device is being connected ? I assume there's a windows-message indicating a new device connection, but I don't have a clue where to find documentation about this. (MSDN isn't always as clear as you'd like it to be ) Ciao, Led Re: How to detect a new device was installed ? (What message/event?)

Do anyone know how to open two windows as soon as I open my application? One window is used to display some output during the running of the application and the other window is used for the user to open some image file. Does anyone know how to do this? Thank you. Re: Opening 2 windows upon startup The_Server25-Jan-04 21:47 The_Server 25-Jan-04 21:47  Hi... ----- If I understand your question (which I dont). If you want your app to be with multi windows. (*in you example 2 windows*) You can call twice "CreateWindow(...)" but then you use the same winproc or You can register 2 difrent classes for 2 diffrent window procs and call "CreateWindow(...)" twice also, but ONE for each registered class =-=-=-=-=-= The-Server Re: Opening 2 windows upon startup hurr1can325-Jan-04 22:18 hurr1can3 25-Jan-04 22:18  HI. Thank you for your reply. What I mean is that when I open my application, it will display two blank child windows (frames) instead of the usual one. Hope this is more clear. Re: Opening 2 windows upon startup The_Server26-Jan-04 5:29 The_Server 26-Jan-04 5:29  I m very sorry... But I dont understand what you want to do. If you are talking about programming in VCPP. Please let me know what are you talking about, I m very intresting in your question... Because I just dont understand it. I have some question for you: How many windows in total? (include the main one) How many & what types if windows you have in total? Also, How many times you need to call RegisterClass(...) =-=-=-=-=-= The-Server Re: Opening 2 windows upon startup hurr1can326-Jan-04 6:07 hurr1can3 26-Jan-04 6:07  Hi. thank you for your reply. I am using VC++ and mfc in my application. Usually if you create a MDI application, when you run the program, only one child frame or window is opened. What I wanted to do is that when my application is double clicked, it runs and two blank child windows should be opened instead of just one as in the normal case. So in total, I have the main window, and two child windows inside the main window. I tried using another CView class for the second child window but it did not work. I keep getting the error "COutputView (the class I created) is not a class or namespace name" and I do not know how to resolve it. Hope you understand now. Thank you. Re: Opening 2 windows upon startup The_Server26-Jan-04 13:47 The_Server 26-Jan-04 13:47  Yes.. It took me some time, But finally I get it. Sorry to disapoint you, But I didn't work with MFC since 1999... It's about 4 years now. =-=-=-=-=-=- The-Server Problem with positioning by pixels controls in Cdialog at font change.... vgrigor25-Jan-04 21:37 vgrigor 25-Jan-04 21:37  In a CDialog I place and draw some controls, like buttons by hands coordinating them in usual pixels. With change of system font proportions of CDialog position and size of native CDialog controls changes not proportionally to pixels... So Proportionality in sizes looses. So Question is: Which functions help to translate pixel coordinates with system font change ? thanks you Re: Problem with positioning by pixels controls in Cdialog at font change....

Where can i find a good socket class Atif Mushtaq25-Jan-04 19:21 Atif Mushtaq 25-Jan-04 19:21  well guys i am tired of using CSocket and CAsyncSocket buggy MFC sockets classes. It was biggest mistake i did when i started two huge projects using these classes .now these projects are complete but the problem is , it is giving satisfactory results but not really good(Normally after some communication CSocket becomes useless , so i have to close it and again establishing connection and it is due to buggy message pumping mechanism of these sockets) so if any have some good implemention of WINSOCK , specially a class which could handle the event notification like OnRecieve , OnCLose as in CSocket , and almost the same public initerface as CSocket etc. It will make it possible to streight away replace CSocket with new one and no change in my existing projects . If some body could refer some tested code in this regard , i 'll be really thankfull to him. No Worries! Re: Where can i find a good socket class Rickard Andersson2025-Jan-04 21:05 Rickard Andersson20 25-Jan-04 21:05  How familiar with Winsock are you? I prefer writing your own class from scratch and implement the features you want and nothing else. I'm doing this right now for a project in school. But you can always try google Rickard Andersson Here is my card, contact me later!

I hope you understand me anyway... i think so TOXCCT Re: Where can i find a good socket class Imran Farooqui26-Jan-04 0:52 Imran Farooqui 26-Jan-04 0:52  In my experience, as far as client side is concerned, CSocket/ASyncSocket should never cause any trouble. Though i personally prefer CAsyncSocket over CSocket, to avoid blocking issues. As such CAsyncSocket requires special care[^]. If we talk about server side, it depends upon the scalability desired (i.e the maximum number of users you want to simultaneously connect) and throughput (Data flow rate into and out of server). If both the attributes are low CAysncSocket should work fine. Otherwise you may need to dig into WinSock API and I/O completion ports.
