问题 I am trying to copy multiple ranges using Excel VBA.

However, the following: Range("A1:B4000, F1:F4000").Copy ...only copies the A1:B4000 range. This is the first problem I am facing. Secondly, I would like to dynamically copy the data to the bottom row, which is not necessarily row #4000. If selecting a single range

问题 I have the following minimal example of my code: fn main() { let names : Vec<Vec<String>> = vec![ vec!["Foo1".to_string(), "Foo2".to_string()], vec!["Bar1".to_string(), "Bar2".to_string()] ]; let ids : Vec<i64> = vec![10, 20]; names.iter().enumerate().flat_map(|(i,v)| { let id : i64 = ids[i]; v.iter().map(|n| (n.clone(), id) ) }); } Now, when I compile that with rustc I get the following error message: error[E0597]: `id` does not live long enough --> main.rs:12:16 | 11 | v.iter().map(|n| | --

问题 Is it possible to copy a file or a folder from one location to another without modifying its attribute data? For example if I have a folder on a network drive and it was created on 2/3/2007 and I want to copy it to my c: drive .. but leave the date/time stamp as 2/3/2007...is that possible? 回答1: I'm not sure if it is possible; however you can use the methods within System.IO.File and System.IO.Directory to reset these attributes back to what they were originally. Specifically the

问题 What would be a fast method to copy/convert an array of Color32[] values to a byte[] buffer? Color32 is a struct from Unity 3D containing 4 bytes, R, G, B and A respectively . What I'm trying to accomplish is to send the rendered image from unity through a pipe to another application ( Windows Forms ). Currently I'm using this code: private static byte[] Color32ArrayToByteArray(Color32[] colors) { int length = 4 * colors.Length; byte[] bytes = new byte[length]; IntPtr ptr = Marshal

问题 Is there a way in to make copy of a variable so that when the value changes of variable 'a' it copies itself to variable 'b'? Example a='hello' b=a #.copy() or a function that will make a copy a='bye' # Is there a way to make # 'b' equal 'a' without # doing 'b=a' print a print b I am having a problem using the Tkinter library where I have checkbutton that has been stored in a list and I'm trying to get the variable that it holds. But it takes around 5 lines of code to reach the variable. Is

问题 I have two classes with the same set of properties, declared using the @property directive in a protocol, they both implement. Now I was wondering if it is possible to automatically populate an instance of the first class with the values from an instance of the second class (and vice-versa). I would like this approach to be robust, so that if I change the of properties declared in the protocol there will be no need to add extra code in the copying methods. 回答1: Yes, given the exact context
