    - by balexandre
    In my .m file I call a method that is inside the same .m file. In the header I have the correct import for the header but I keep getting this alert: What am I doing wrong? What should I do in order to make this error disappear? I'm kinda lost here :-( Even if I changed this to: NSString *path = [[NSString alloc] initWithString:@"...."]; [self parseXMLFileAtURL:path]; [path release];

  • C++ TerminateProcess function

    - by jemper
    I've been searching examples for the Win32 API C++ function TerminateProcess() but couldn't find any. I'm not that familiar with the Win32 API in general and so I wanted to ask if someone here who is better in it than me could show me an example for, Retrieving a process handle by its PID required to terminate it and then call TerminateProcess with it. If you aren't familiar with C++ a C# equivalent would help too.

  • How can I define multiple types with the same name and different type parameters using Reflection Em

    - by wawa
    How can I generate types like these using the System.Reflection.Emit libraries: public class Test<T> {} public class Test<T1, T2> {} When I call ModuleBuilder.DefineType(string) with the second type declaration, I get an exception because there is already another type in the module with the same name (I've already defined the type parameter on the first type). Any ideas?

  • Why does isNaN(123.) return false?

    - by vivekraman
    Hi, Why does the Javascript function call isNaN(123.) return false? Is this a universally acceptable number or will it cause errors downstream? I'm validating whether a value is a valid decimal using isNaN along with split. Are there cross-browser issues with isNaN? Should I use a bespoke implementation? Thanks.

  • [MS-DOS] Read command-line parameters to .bat from file

    - by John
    I have a build.bat file which uses %1 internally... so you might call: build 1.23 I wanted it to read the parameter from a separate file, so I tried putting "1.23" in version.txt and doing: build < version.txt But it doesn't work. Isn't this how piping works? Is what I want possible and if so how?

  • what is the probability that the next random number will equal current one?

    - by I__
    if i do this in a worksheet: =RAND() i also specified that i want only 2 decimal places and for example let's say that rand() = 0.07 what is the probability that when i call this function again i will get 0.07 ?? i know that ideally if we assume 100% randomness, the answer would be 1/ (10 * 10) because there are only 100 possible combinations, but what would it be according to the way excel generates a random number?
