copy

问题 I am trying to copy a CImage so that I can do some manipulation with it's pixels. I've tried this where source is a pointer to a loaded CImage object. CImage* dest = new CImage(*source); However this doesn't seem to work and I believe source and dest are pointing to the same memory. How would I create a new copy totally detached from the previous CImage? 回答1: If this is a question about MFC/ATL CImage then you can create new instance and use Create to initialize it to the size of the original

问题 Based on a previous question boost::interprocess Containers of containers NOT in shared memory I am able to create objects in the shared memory and on the heap. What I want now is a template deep copy function to copy between heap an shm usable with all interprocess vectors independent to the allocator. #include <boost/interprocess/containers/vector.hpp> #include <boost/interprocess/allocators/allocator.hpp> #include <boost/interprocess/managed_shared_memory.hpp> #include <boost/range

问题 Basically I want to write a little batch script that does the following - I have two folders, A and B... A has 10 files and B has 100. I want to compare the names of the files in each folder and if any in B have the same name as in A, then to copy them to folder A and overwrite the original file. I was trying to start off by doing a "for" command on folder A but then I would have to follow that with an IF to compare the filenames which I have no idea how to express correctly for /r "C:

问题 I have an .html file containing only text(formatted somehow).I am wondering if there is a way to copy all of the text(like if would do with ctrl+A) and assign it to a string So I can then export it to .txt file ? All this must happen from the code-behind(opening the html, selecting the text and assigning it to a string). In the Microsoft.Office.Interop I remember that there was an option for copying the active window selection or something, so I was wondering if this is possible and here. 回答1

问题 So the basic question is, how can I make table nicely copy pastable from IE to Excel or OpenOffice calc. The page is located here: http://tuudik.lohv.eu/Asjad/EURXML/ The table is created dynamically by PHP code. There's a button with tekst "Vali tabel!" which means, it selects the table. Then I want to copy it, for example using CTRL + C and paste it into a spreadsheet. What are the best options? Should I create a hidden div what then has the same Data like in the table but formatted other

问题 I would like to read some data from the webview.db database that is created when your app uses a WebView. However, that database is managed by classes that are mostly package level or do not provide much in the way of access through apis. Since I can't share their database objects or locks, how can I safely read content from that database without getting "database is locked" errors or similar exceptions? I only need to read, I do not need to write. If there is no way to safely aquire sql

问题 I'm trying to copy entire rows of the Sheet ‘All’ to another sheet according to the data in column D. There are multiple values in column D (Homework/Advanced/Beginner) and the sheets these rows need to be copied to have corresponding names. (Homework to Homework sheet.) The data in Sheet ‘All’ will be added on to and the new data needs to be copied without duplicating the ones that are already there. 回答1: It's not a big problem. The best thing is to keep things simple and copy everything

问题 I want to extract the Test #. and the description that follows into two different columns side by side. Currently I have one long string. I want to break the string into two sets and extract only the needed information. I have attached a screenshot to make it more clear. In the past I have used the MID function and FIND to extract text from strings, but since the strings here vary in length and content I'm not sure how to do this. Thank you in advance!! 回答1: Formula for cell A9 : = LEFT(A2

问题 Consider the following code: LargeObject getLargeObject() { LargeObject glo; // do some initialization stuff with glo return glo; } void test() { LargeObject tlo = getLargeObject(); // do sth. with tlo; } A simple compiler would create a local LargeObject glo on the getLargeObject() stack and then assign it to tlo in test() when returning, which involves a copy operation. But shouldn't a clever compiler realize that glo is going to be assigned to tlo and thus just use tlo's memory in the

问题 I would like to use JavaScript to clean up text that’s being copied from my site. I use snippets like this: body { vertical-align: middle; ➊ } Where ➊ indicates comment later on. I want readers to copy this snippet and use it – so I need to delete that Unicode marker. How can I access text that’s being copied and make changes to it? I considered deleting marker(s) from snippet when user clicks (mousedown) on it, so she could select the text, copy it and then I would restore markers but it
