问题 Per File Parameter 'help text' on Jenkins build, Accepts a file submission from a browser as a build parameter. The uploaded file will be placed at the specified location in the workspace, which your build can then access and use. This is useful for many situations, such as: Letting people run tests on the artifacts they built. Automating the upload/release/deployment process by allowing the user to place the file. Perform data processing by uploading a dataset. The name of the submitted file

问题 I have checked several methods for converting text files to binary and found some answers here as well. However, most of them confused me due to Unity .NET compatibility and I am also confused about the structure of how I convert text to binary. I have a text file (exported point cloud) which holds positions of points in 3D space and color information like this: X Y Z colorvalues -0.680891 -90.6809 0 204 204 204 255 I was reading this to create meshes in run time with a script like this:

问题 Is there a way to close a pop up window after the page writes binary data (PDF) to the browswer? Here are the details: Whenever my web appilcation needs to print, it will pass some parameters over to a pop up window, which will display the print options. When the user clicks on the Print button, it will set the src of a iframe that will call the page that does the printing. I have PDFConverter to convert URL / HTML to a pdf file. At the end of the converting, it will write the binary to the

问题 I have made the previous problem simpler to get the answer and understand it completely. The problem is that I want to write a C++ program that converts an ordinary text file into binary and then reads that binary file and converts it to a text file so that this text file equals to first text file. I have wrote this simple code for it. int main() { string name1 = "first", name2 = "sec", name3 = "third"; int j = 0, k = 0; ifstream ifs(name1.c_str()); // Here I want to read from the ordinary

问题 I'm using rubyzip library for zipping files. But I encounter problems. I try: Zip::ZipOutputStream.open('c:/sites/efiling2/test.zip') do |zos| zos.put_next_entry("test.rtf") zos.write IO.read('c:/sites/efiling2/test.rtf') zos.put_next_entry("test.jpg") zos.write IO.read('c:/sites/efiling2/test.jpg') end But write method restricts a size of original files. For example my source file test.jpg has a size of 11913 bytes , but in archive there is a file test.jpg with size 11551 bytes . With test

问题 I need to add a file to a git repository, and I need the correct type of line ending. In perforce, I would just use " -t binary " to force the file to binary, but I don't know how to set the file to binary in GIT. The repository is rather large, so I don't want to make a global change. The new file is .html , and I already have thousands of .html files whose type I don't want to change. I don't have a choice about the name for the new file either. So, how do I force just one file to binary in

问题 I am trying to write a basic binary VTK file to display some data using ParaView but I have some errors and I don't understand why. Here is my test code in C++: #include <iostream> #include <fstream> double myarray[72] = { 0,0,0,1,0,0,2,0,0,3,0,0,4,0,0, 5,0,0,0,1,0,1,1,0,2,1,0,3,1,0, 4,1,0,5,1,0,0,2,0,1,2,0,2,2,0, 3,2,0,4,2,0,5,2,0,0,3,0,1,3,0, 2,3,0,3,3,0,4,3,0,5,3,0}; int main() { std::ofstream vtkstream("test01.vtk", std::ios::out | std::ios::trunc); bool ascii = false; if (vtkstream) {

问题 This morning I asked here why my Python code was (a lot) slower then my F# version but I'm wondering whether the F# version can be made faster. Any ideas how I could create a faster version of the below code that reads a sorted list of unique indexes from a binary file with 32-bit integers? Note that I tried 2 approaches, one based on a BinaryReader, the other one based on MemoryMappedFile (and some more on Github). module SimpleRead let readValue (reader:BinaryReader) cellIndex = // set

问题 I have this SQLite table: create table mytable ( aid INTEGER NOT NULL PRIMARY KEY, bid INTEGER NOT NULL, image BLOB ); And I want to insert a binary file into the image field in this table. Is it possible to do it from the sqlite3 command line interface? If so, how? I'm using Ubuntu. Thank you! 回答1: You may use a syntax like : echo "insert into mytable values(1,1, \"`cat image`\")" | sqlite3 yourDb i'm not sure for the " around blob's value. Note the backquotes around cat command, means the

问题 The spark python api currently has limited support for loading large binary data files, and so I tried to get numpy.fromfile to help me out. I first got a list of filenames I'd like to load, e.g.: In [9] filenames Out[9]: ['A0000.dat', 'A0001.dat', 'A0002.dat', 'A0003.dat', 'A0004.dat'] I can load these files without problems with a crude iterative unionization, for i in range(len(filenames)): rdd = sc.parallelize([np.fromfile(filenames[i], dtype="int16", count=-1, sep='')]) if i==0: allRdd =
