How bind socket to device in windows?

阅读更多关于 How bind socket to device in windows?

I have same network cards in computer. All cards has identical IP. I need to bind socket to specific card. In linux I can use flag SO_BINDTODEVICE. How I can do this in windows. P.S. This needed for UDP sockets. Ezz I answered a similar question here: Using a specific network interface for a socket in windows AFIK: in Windows XP and Windows Server 2003 IP4 I believe you can't, but for IP6 you can. And for Windows Vista and Windows 2008 you can (except for certain circumstances). Hope that helps 来源： https://stackoverflow.com/questions/1951578/how-bind-socket-to-device-in-windows

Windows shell: How can I get the audio device(s) name(s)?

阅读更多关于 Windows shell: How can I get the audio device(s) name(s)?

问题 I am not sure if this is strictly a programming question, as long as I don't mind to use additional software in order to solve the problem, as long as it keeps being scriptable or command-line (this is: a not GUI solution). Anyway, I have posted another (a bit different) question at SuperUser. By the way, I will update here if I get the answer there. My Windows program (just a shell script) invokes VLC command-line in order to record audio from the audio card and stream it out, like: vlc

That shows you the kernels of view of what memory ranges are assigned to who. If you want more detail you'll need to look at each individual driver. You might get some more information from /proc

How can I get iphone device type?

阅读更多关于 How can I get iphone device type?

问题 I want to get iphone device type if it is iphone 2 or 3G or 4 in xcode 4.0. Is there any way to get it? If it is, please tell me. 回答1: Caleb is right, you shouldn't check for device type, but for functionality. For example, you can check whether the device supports multitasking like so: UIDevice *device = [UIDevice currentDevice]; if ([device respondsToSelector:@selector(isMultitaskingSupported)] && [device isMultitaskingSupported]) { // ...code to be executed if multitasking is supported. //

What USB devices (friendly name) are currently connected to PC?

阅读更多关于 What USB devices (friendly name) are currently connected to PC?

Can I get a list of what devices are currently connected to the computer? I checked this and this thread, but I can't seem to find the actual names (i.e. iPod Touch 4 etc.) is there a way to find the name of the device in human language, so I can display this list (of matching devices) to the user? Any PI that gets this info? Update: I notice that the computer's device management is able to show this info, meaning it does exist somewhere, I just don't know the right place to access it. I did found this info in the registry, but there is some inconsistency between the "Mighty Drive" and the

Is there a way to convert the coordinate system after a change to Landscape Orientation?

阅读更多关于 Is there a way to convert the coordinate system after a change to Landscape Orientation?

问题 In a view-based iPhone OS application, I change the orientation from the initial portrait orientation to a landscape orientation (UIInterfaceOrientationLandscapeRight). But now the x,y origin (0,0) is in the lower-left corner (instead of the usual upper-left) and each time I want to do something that involves coordinates I must re-calculate to compensate for the new coordinate system. I have also noticed that my views within the new coordinate system are not behaving normally at times. So, Is

iAd ADBannerView appears tinted on Device

阅读更多关于 iAd ADBannerView appears tinted on Device

I'm getting a tinted adBannerView on the device, instead the normal adBannerView as it appears in the Simulator. Any ideas on this? On the device, go to Settings > Developer and disable the option "Highlight Clipped Banners" to remove the colored layer. If enabled, the colors show you if the iAd banner view is clipped (red) or not (green). Note that this setting is system-wide, and affects not only the development builds from your app, but also production builds from all other apps downloaded from the App Store. If you change this setting, you might have to restart the app to see changes. This
