copy

问题 I can copy all the files from multiple directory's but what I want to do is copy all of the directory's with the files inside them as they are where I am copying the from and not putting just the files in my target folder. Here is my code so far { string SelectedPath = (string)e.Argument; string sourceDirName; string destDirName; bool copySubDirs; DirectoryCopy(".", SelectedPath, true); DirectoryInfo dir = new DirectoryInfo(sourceDirName); DirectoryInfo[] dirs = dir.GetDirectories(); // If

问题 I would like to copy a picturebox to another picturebox, but I do not want them to change with each other.

How would I be able to do that? 回答1: Probably the best way to maintain clean code is to create an extension method, also note that your second picturebox is

问题 I have 2 tables stuff and nonsense . nonsense is not the same size as stuff ; in this case it is has fewer rows, but it may have more. The structures are something like this: CREATE TABLE stuff ( id INT PRIMARY KEY, details VARCHAR(MAX), data VARCHAR(MAX) ); CREATE TABLE nonsense ( id INT PRIMARY KEY, data VARCHAR(MAX) ); The stuff table is already populated with details , but data is NULL for now.

问题 I am trying to make a simple tool which will copy/move files with certain extension from one place to another. Everything is working out pretty much fine, but I am trying to make it possible to type in the directory where you want to copy from, and choose the directory where you want to copy to. myGUI=Tk() myGUI.geometry("400x200+100+200") myGUI.title('Copy dat') Source=StringVar() Destination=StringVar() MySource=Entry(myGUI, textvariable=Source).grid(row=9, column=2) MyDestination=Entry

问题 I'm currently creating some fixtures for some tests and i faced this error. Have you an idea about how to solve it ? I've so many fixtures to copy paste it. A new entity was found through the relationship '***' that was not configured to cascade persist operations for entity: ***. To solve this issue: Either explicitly call EntityManager#persist() on this unknown entity or configure cascade persist this association in the mapping for example @OneToOne(..,cascade={"persist"}). If you cannot

问题 class X { int i; public: X(int m) : i(m) {}; X(const X& x) { //cout "copy constructor is called\n"; } const X opearator++(X& a,int) { //cout "X++ is called\n"; X b(a.i); a.i++; return b; } void f(X a) { } }; int main() { X a(1); f(a); a++; return 0; } Here when function 'f' is called copy constructor is getting called as expected. In case of a++, operator++ function is called but when it returns "copy constructor is not called". why "copy contructor is not called while returning from function
