A UIColor is not mutable. I usually do this with colors, fonts and images. You could easily modify it to use singletons or have a static initializer. @interface UIColor (MyProject) +(UIColor *) colorForSomePurpose; @end @implementation UIColor (MyProject) +(UIColor *) colorForSomePurpose { return [UIColor colorWithRed:0.6 green:0.8 blue:1.0 alpha:1.0]; } @end
Both operands need to be object. Use explicit cast: (object)table.Value ?? DBNull.Value;
Use an overload of TextBoxFor() with an htmlAttributes argument. This argument should be an anonymous object with all attributes you wish to assign to the input. For example, if you want to set the placeholder and class attributes: @Html.TextBoxFor( m => m.Email, new { placeholder = “Email”, @class = “form-input” } )
As @stefan said using fopen() with “w” mode will do the job for you. When you open a file with “w” flag it creates an empty file for writing. If a file with the same name already exists its contents are erased and the file is treated as an empty new file. If the file … Read more
The standard method of logging (in my experience) is to use either the stdout or stderr streams. In C++ to use these you would need to include iostream, and use as below: #include <iostream> int main(int argc, char* argv[]) { using std::cout; using std::cerr; using std::endl; cout << “Output message” << endl; cerr << “Error … Read more
How about using the Guid constructor which takes a byte array? Guid guid = new Guid(binaryData); (You can then use Guid.ToString() to get it in text form if you need to.)
You can use the JToken.ToObject<T>() method. JToken token = …; int value = token.ToObject<int>();
I had this problem with VS 2010, and it was as simple as terminating the “WebDev.WebServer40.EXE” process. Although the icon was no longer showing in the system tray, the process was still running.
Although Archedius’s method works, officially it is deprecated and instead recommended way to programmatically create a template is to load XAML from a string or a memory stream using the Load method of the XamlReader class like this… public DataTemplate Create(Type type) { StringReader stringReader = new StringReader( @”<DataTemplate xmlns=””http://schemas.microsoft.com/winfx/2006/xaml/presentation””> <” + type.Name + @” … Read more
Everyone is correct in the use of @Html.Raw() but I want to point out to be careful with this, as it can make your site susceptible to XSS vulnerabilities. I would combine the @Html.Raw(ViewBag.SomeMessage) with Microsoft’s Anti-XSS Library to make sure you do not introduce any vulnerabilities from this. Edit: The advantage of the Anti-XSS … Read more
