default

I want to find out the default network in use. My current method was to find all IP addresses and compare it to the default gateway IP address, but that sounds silly. What is the correct way of doing it ? UPDATE I want to use a C program, not by commands ... You can try a slightly dirtier but infinitely easier approach: cnicutar@lemon:~$ ip route show to 0.0.0.0/0 default via X.Y.Z.T dev eth0 proto static ^^^^ So you can try: FILE *cmd = popen("ip route show", "r"); fgets(str, LEN, cmd); Then you can use strtok , strstr etc. 来源： https://stackoverflow.com/questions/10513673/linux-c-how-to-know

I'm just about to start a new project of mine and am currently evaluating some techniques for localization, modularity etc. I have (at least in my opinion) a pretty good approach to localization but now I struggle to find a good solution for databinding. I want to bind values of textfields etc. (UIElements in general) to a specific method in the DataContext of the form. The method looks like this: public void GetValue(string name) where name is a "path" in the form of "node/subnode/subsubnode". I thought about using a ValueConverter for the binding and this worked out pretty good till now. My

I'm a novice programmer and have developed a notepad replacement application for my own needs (with some more features). When I double click a .txt file (or a customizable extension such as .abc), I want the file to run in my application just like notepad. I read about File Association with programs but I didn't get much of it. Can someone point me to how I would do this? Just give me a few ideas, I would really like to do this and have an option for my users to set the application as the default text editor. Help would be much appreciated. If you are using click-once deployment (i.e. "publish

I have a DateTime property on one of my Model classes and want to set it's default vaule to Now. The below code is what I had hoped would work but won't compile. It doesn't like the System.DateTime.Now call: [DisplayFormat(DataFormatString = "{0:d}", ApplyFormatInEditMode = true)] [Display(Name = "To Date")] [Required(ErrorMessage = "To Date is required.")] [DefaultValue(System.DateTime.Now)] public DateTime DateTo { get; set; } Any ideas? In the model class: private DateTime _date = DateTime.Now; public DateTime Date { get { return _date; } set { _date = value; } } In C# 6 or higher you can

Note: I've tried searching on google, but couldn't find what I was looking for. Browsers have some default styles they use for rendering form elements, which is different from browser to browser. Is there a way to reset all of the native browser styles for form elements like select, radios, checkbox etc, to make a consistent look across browsers? I've made a quick example: form elements http://grab.by/grabs/34db87ee1ad93e031cc72808feb2c8e7.png As can see the form elements are rendered slightly differently. What I would like, is some styles, that can reset them, to look alike, for IE, Firefox
