My task is to convert a data file from big endian to little endian & vice versa using C. I have been looking online for about 3 hours now for other examples and reading my text book, however I am so stuck on how to even start this function. So far I have the order of events correct (1 through 4) but inside my convert_and_save function do I have to create a char array using → char buffer[4]; ? Can someone please help me? even if you just give me clues on what to look up, I would greatly appreciate it. I need to write a function called: void convert_and_save(struct record item, FILE * output

How to use EnumConverter with CsvHelper

I'm using CsvHelper to serialize a class to csv file - until here everything works well. Now I'm trying to find a way to convert the class's enum properties to their int value in the csv, so I could use the CSV for bulk insert later. I found out the EnumConverter class in CsvHelper but I can't figure out how to properly use it, as all my tries are failing. Here is my mapping class code public sealed class MyMapping : CsvClassMap<TradingCalendarException> { public MyMapping() { EnumConverter enumConverter = new EnumConverter(typeof(CalendarExceptionEntityType)); Map(m => m.ExceptionEntityType)

Convert hexadecimal string to IP Address

I want to convert a string value (in hexadecimal) to an IP Address. How can I do it using Java? Hex value: 0A064156 IP: 10.6.65.86 This site gives me the correct result, but I am not sure how to implement this in my code. Can it be done directly in an XSLT? try this InetAddress a = InetAddress.getByAddress(DatatypeConverter.parseHexBinary("0A064156")); DatatypeConverter is from standard javax.xml.bind package You can split your hex value in groups of 2 and then convert them to integers. 0A = 10 06 = 06 65 = 41 86 = 56 Code: String hexValue = "0A064156"; String ip = ""; for(int i = 0; i <

I'm changing from IceFaces to PrimeFaces (I really wanted to change to RichFaces but cause a bug in new version, I won't) and I'm havinng some dificults to implement correctly primefaces autoComplete. According to his manual I just need to implement a method that returns a list of objects, and in this case a converter is required. The list I'm returning is a list of javax.faces.model.SelectItem, I really can't understand why I need to create a converter to this, but lets continue. I've created a simple converter just to test, but primefaces don't recognizes my converter and returns this error

How to bind to a StaticResource with a Converter?

▼魔方 西西 提交于 2019-11-29 00:59:05
I want to use a Converter to change the value of a StaticResource before assigning it to a property. Is there a way to simulate a Binding that will just set the value of the StaticResource after converting it? Something like {Binding Value={StaticResource myStatic}, Converter={StaticResource myConverter}} ? This works: <TextBox Text="{Binding Source={StaticResource myStatic}, Converter={StaticResource myConverter}, Mode=OneWay}" /> Note that you have to bind one way, because the binding requires a path attribute otherwise. This makes sense, as otherwise the binding would have to replace the

Ok, it was a nice surprise (after writing it several times) to find that there already is a BooleanToVisibilityConverter in System.Windows.Controls namespace. Probably there are more such hidden time-savers. Anyone got some? MrTelly I did a quick trawl using the Object Browser and this is what I have.
