overwrite

I have an installer of an application that needs to install over any existing version, regardless of version number. Instead, I've got an installer that constantly says that I need to go to add/remove programs. That's very frustrating behavior for my testers, since it just slows them down for no real reason in their minds-- the previous installer package would always just install, deleting any files that were previously there, so they never had to do that step. We also have a (large) customer base that's been similarly trained, in that whatever version I install right now should overwrite

I can't seem to figure out how to write data to a file without overwriting it. I know I can use File.appendtext but I am not sure how to plug that into my syntax. Here is my code: TextWriter tsw = new StreamWriter(@"C:\Hello.txt"); //Writing text to the file. tsw.WriteLine("Hello"); //Close the file. tsw.Close(); I want it to write Hello every time I run the program, not overwrite the previous text file. Thanks for reading this. Pass true as the append parameter of the constructor : TextWriter tsw = new StreamWriter(@"C:\Hello.txt", true); sarvesh Change your constructor to pass true as the

I have a Sinatra app, hosted on Heroku. Lately, I've been developing that same app from a different folder. It's not a branch, it's just a parallel app / directory with identical contents but different code. I want to push this new app to Heroku, overwriting the app that's currently there. I don't want to merge the two locally, just continue from the new one while keeping the old. What's the proper command sequence for this? I have doubts about running heroku create , as that will result in a new app. Thanks! Firstly this is certainly possible. The process is quite simple, firstly we need to

Say, the code class Derived: public Base {....} Base* b_ptr = new( malloc(sizeof(Derived)) ) Base(1); b_ptr->f(2); Derived* d_ptr = new(b_ptr) Derived(3); b_ptr->g(4); d_ptr->f(5); seems to be reasonable and LSP is satisfied. I suspect that this code is standard-allowed when Base and Derived are POD, and disallowed otherwise (because vtbl ptr is overwritten). The first part of my question is: please point out precise precondition of such an overwrite. There may exist other standard-allowed ways to write over. The second part of my question is: is there any other ways? What are their precise

I need to copy all *.doc files (but not folders whose names match *.doc ) from a network folder \\server\source (including files in all nested folders) to a local folder C:\destination without preserving the nested folders hierarchy (i.e. all files should go directly into C:\destination and no nested folders should be created in C:\destination ). In case there are several files with the same name from different subfolders of \\server\source , only the first one should be copied and never overwritten then — all conflicting files found later should be skipped (there could be many cases like this
