I am programing plug-ins for 3ds MAX and never deal with hardware earlier. There is some 3D glove produced by www.essentialreality.com. So am going to write plug-in which enables users to work with this device inside the MAX. So first question that appeares - how to reach this device and its output parameters. I am downloadig SDK from essentionalreality site just now. And hope it will help a. But this area is very new for me so any your help is essential. Thanka a lot. Re: USB device access from DLL Antti Keskinen3-Oct-04 5:30 Antti Keskinen 3-Oct-04 5:30  Most obviously the SDK already allows access to the device driver of the glove. This level of abstraction is useful as it provides means of getting data from the glove without worrying about the actual USB interface. The better the SDK is, the more lower level access it allows. You should download the SDK and see it's documentation. I'm sure it will provide you with a good kickstart. I believe that the glove driver is primary emulating a mouse's behaviour in Windows (thus working automatically in 3DS Max) It then depends on what you wish to do with the glove. Write the plug-in so that you can first use a mouse to do the things you please. Then take the glove into use, and see the SDK for any special properties it might have (such as 3D movement), and utilize them. -Antti Keskinen ---------------------------------------------- The definition of impossible is strictly dependant on what we think is possible. How can I subclass MessageBox ? Routine_3-Oct-04 1:56 Routine_ 3-Oct-04 1:56  Hello Can anybody tell me how to subclass MessageBox ... particular I need to subclass 'OK' button or I want to change background color of one messagebox... Can anybody tell me how can do this ?? Re: How can I subclass MessageBox ? Gary R. Wheeler3-Oct-04 2:31 Gary R. Wheeler 3-Oct-04 2:31  MessageBox is an API function. Unfortunately, the dialog it displays isn't customizable through subclassing or through the mechanisms used by the common dialogs. Basic information on MessageBox can be found here[^] in the MSDN. You can, however, replicate the functionality of MessageBox pretty easily. It's a simple dialog box that displays an icon, text, and up to four buttons. Once you've replicated it, you could customize it as necessary. Software Zen: delete this; Re: How can I subclass MessageBox ? Niklas L3-Oct-04 2:45 Niklas L 3-Oct-04 2:45  If you use MFC you can use the AfxMessageBox() function instead. Then you can change the behaviour in CWinApp::DoMessageBox() to whatever. Re: How can I subclass MessageBox ? Yulianto.3-Oct-04 19:02 Yulianto. 3-Oct-04 19:02  You can`t subclass MessageBox, it`s API <italic>Work hard and a bit of luck is the key to success. You don`t need to be genius, to be rich. Replacing Windows SysTray Clock Axonn Echysttas2-Oct-04 23:39 Axonn Echysttas 2-Oct-04 23:39  Hi everybody, I got a short but rather difficult question: does anybody know how the Window SysTray clock can be hidden/replaced by another window? For example a custom window made by the programmer. This has been troubling me for some time... Thank you! The Greater Mind Balance Re: Replacing Windows SysTray Clock ThatsAlok3-Oct-04 19:32 ThatsAlok 3-Oct-04 19:32  Hello buddy heer is solution first using the FindWindow api find the Window that contain systray timer like this. HWND hWnd=::FindWindow("TrayClockWClass",NULL); and for hiding ::ShowWindow(hWnd,SW_HIDE) and for replacing the Timer window, craete a static value with parent class= ToolbarWindow32 and according to coordinate system of your computer place it over hidden System Tary CLock ----------------------------- "I Think It Will Help" ----------------------------- Alok Gupta visit me at http://www.thisisalok.tk Re: Replacing Windows SysTray Clock Axonn Echysttas4-Oct-04 0:37 Axonn Echysttas 4-Oct-04 0:37  Hey, thanks for answering Alok. I didn't mention that my current project is in Visual Basic 6. It's more than a year old and back then I wasn't so much into C++ or C# ::- )... anyway, I handle VB6 pretty well and I can use API to call the FindWindow function and the ShowWindow function as well. I got a bit confused by the last thing you told me: You mean create a window that inherits the ToolbarWindow32 class? That I don't know if I can do in VB6... And another thing... as we all know, the SysTray clock has a fixed size, but what if I want my window to be a bit larger then that? Let's say I want it of a fixed size of 300 pixels. Thanks again for helping. Anybody who helps will be in the "thanks to..." list of my program (which is going to be freeware) when I finish it. It's a clock with alarms, internet synchronization, calendar, to do list and lots of other stuff in it. It's gonna have at least 10 great functionalities, but I`m still only 30% done with it... this systray thing is pretty important because not all people have their taskbar on autohide like me ::- ) Have a nice day everybody. The Greater Mind Balance Re: Replacing Windows SysTray Clock ThatsAlok4-Oct-04 4:04 ThatsAlok 4-Oct-04 4:04  do one thing first Hide the timer,then using NOTIFYICONDATA create you own icon based on time. NOTIFYICONDATA strcuture is used in making system tray application. i think you have to play this trick ----------------------------- "I Think It Will Help" ----------------------------- Alok Gupta visit me at http://www.thisisalok.tk Re: Replacing Windows SysTray Clock Axonn Echysttas4-Oct-04 23:34 Axonn Echysttas 4-Oct-04 23:34  Yes, but this means adding a separate icon for each digit of the clock, so you can see it. That means at least 4 icons, I think its kind of hard to handle, specially if you think that sometimes some other icons might interfere. For example the sound volume icon could get in the middle of those. Using NOTIFYICONDATA I cannot create a window of ... say... 300 pixels and place it instead of the clock. I think your first idea is what could help. You said that... "and for replacing the Timer window, craete a static value with parent class= ToolbarWindow32 and according to coordinate system of your computer place it over hidden System Tary CLock" This also restricts me to using the size of the hidden window of the clock, but it does allow me to place there ANY window right? Even a window containing a drawing not limited by the 16x16 pixels of an icon. What I am really looking for is a way to add there, instead of the clock, some other window of mine except at a biger size, or smaller... customizable! I saw such a thing running on a Windows 2000 system so I`m sure it is somehow possible, but I really don't understand how it can be done. The window on that Windows 2000 was replacing the clock and it had more than 200 pixels in lenght. This is a challenging problem to solve... hmmm...

Dominik Reichl2-Oct-04 23:34 Dominik Reichl 2-Oct-04 23:34  Hello! I have a dialog-based application. The main dialogs shows another dialog before showing itself (think of a login dialog before the main dialog). Now my problem is that the login dialog isn't shown in the taskbar, only the main window shows up when you have logged in. Now the question: how do I show up the first dialog in the taskbar?? Dominik _outp(0x64, 0xAD); and __asm mov al, 0xAD __asm out 0x64, al do the same... but what do they do?? (doesn't work on NT) Re: Show dialog in taskbar? Gary R. Wheeler3-Oct-04 2:36 Gary R.
