问题 With FileVersionInfo class is very easy to read file extra information, but is there any way i can change it? Thanks. 回答1: There's no class in the .NET Framework that lets you do that easily. File version data is stored as a native resource, so it can be changed by functions like BeginUpdateResource. But it requires detailed knowledge about the format in which it's are stored in the executable. 来源： https://stackoverflow.com/questions/3785966/c-sharp-change-fileversioninfo-for-any-file

问题 I have code that does async file uploads which works fine on my dev vm but after I deployed it to the client system, I keep getting this error: "error writing mime multipart body part to output stream" I know this is the line that is throwing the error but I can't seem to figure out why: //Read the form data and return an async task. await Request.Content.ReadAsMultipartAsync(provider); The file size was only 1MB and I even tried different file types with much smaller sizes. Why would this

问题 I want to read numbers(integer type) separated by spaces using scanf() function. I have read the following: C, reading multiple numbers from single input line (scanf?) how to read scanf with spaces It doesn't help me much. How can I read numbers with space as delimiter. For e.g. I have following numbers as input 2 5 7 4 3 8 18 now I want to store these in different variables. Please help. 回答1: I think by default values read by scanf with space/enter. Well you can provide space between '%d' if

问题 I have defined a record which has lots of fields with different types (integer, real , string, ... plus dynamic arrays in terms of "array of ..."). I want to save it as a whole to a file and then be able to load it back to my program. I don't want to go through saving each field's value individually. The file type (binary or ascii or ...) is not important as long Delphi could read it back to a record. Do you have any suggestions? 回答1: You can load and save the memory of a record directly to

问题 In a file I've blocks of queries separated by blank lines (can be one or more blank lines). Is there a better way to get the queries into a list ? Ex File: select * from tbA where colA= '2' select * from tbB where colB = 'c' order by colc select * from tbC Code I've so far: queries = list() with open(sql_file_path, 'rb') as f: lines = f.readlines() i = 0 while i < len(lines): query = '' while i < len(lines) and not lines[i].isspace(): query += lines[i] i += 1 while i < len(lines) and lines[i]

问题 Currently, the logic in glibc source of perror is such: If stderr is oriented, use it as is, else dup() it and use perror() on dup() 'ed fd . If stderr is wide-oriented, the following logic from stdio-common/fxprintf.c is used: size_t len = strlen (fmt) + 1; wchar_t wfmt[len]; for (size_t i = 0; i < len; ++i) { assert (isascii (fmt[i])); wfmt[i] = fmt[i]; } res = __vfwprintf (fp, wfmt, ap); The format string is converted to wide-character form by the following code, which I do not understand:

问题 I have an application in which the user interacts with a database and prepares a report of what he needs. The item prices are listed in the database. Once he chooses the items then he generates a report in Excel format. When he hits the Generate a Report button, he is asked where to save the report. These are all good. The problem is that when he saves the report and hits the Generate A Report button, he is able to save the same file with the same name at the same location when a file of the

问题 This is weird… and I can't figure out for the life of me why it's doing it this way. I've got a folder full of various CoffeeScript, SASS, HTML, and XML files. I've got a Ruby script that's taking them all, compiling them, and minifying them into one master XML file (it's for iGoogle Gadget development). This script takes command line args using trollop (I only state this to clarify my code below). I want this script to copy this file from the current directory where it's created to a
