As @stefan said using fopen() with “w” mode will do the job for you. When you open a file with “w” flag it creates an empty file for writing. If a file with the same name already exists its contents are erased and the file is treated as an empty new file. If the file … Read more
These are utilities that I use to download files cross-browser. The nifty thing about this is that you can actually set the download property of a link to the name you want your filename to be. FYI the mimeType for binary is application/octet-stream var downloadBlob, downloadURL; downloadBlob = function(data, fileName, mimeType) { var blob, url; … Read more
To expand on Henk’s answer, you need: string rootFolderPath = @”C:\\SomeFolder\\AnotherFolder\\FolderCOntainingThingsToDelete”; string filesToDelete = @”*DeleteMe*.doc”; // Only delete DOC files containing “DeleteMe” in their filenames string[] fileList = System.IO.Directory.GetFiles(rootFolderPath, filesToDelete); foreach(string file in fileList) { System.Diagnostics.Debug.WriteLine(file + “will be deleted”); // System.IO.File.Delete(file); } BE VERY CAREFUL! Note that I’ve commented out the delete command. Run … Read more
The Get-Content command returns each line from a text file as a separate string, so will give you an array (so long as you don’t use the -Raw parameter; which causes all lines to be combined to a single string). [string[]]$arrayFromFile = Get-Content -Path ‘C:\USER\Documents\Collections\collection.txt’ In his excellent answer, mklement0 gives a lot more detail … Read more
Yes, unless you need the program you exec to have access to that file descriptor. You can also close the file descriptor manually in the child process before calling exec, but that’s more error prone.
Reading and writing binary files is pretty much the same as any other file, the only difference is how you open it: unsigned char buffer[10]; FILE *ptr; ptr = fopen(“test.bin”,”rb”); // r for read, b for binary fread(buffer,sizeof(buffer),1,ptr); // read 10 bytes to our buffer You said you can read it, but it’s not outputting … Read more
From the docs: If no encoding is specified, then the raw buffer is returned. Which might explain the <Buffer …>. Specify a valid encoding, for example utf-8, as your second parameter after the filename. Such as, fs.readFile(“test.txt”, “utf8”, function(err, data) {…});
RandomAccessFile exposes a function: seek(long pos) Sets the file-pointer offset, measured from the beginning of this file, at which the next read or write occurs.
Instead of File.ReadAllText() better use File.ReadLines(@”C:\file.txt”); It returns IEnumerable (yielded) so you will not have to read the whole file if your string is found before the last line of the text file is reached
That is the null character, in a format (which Vim uses a lot, as you’ve probably noticed) called caret notation. Basically, somehow you’re getting bytes full of zeros into your file. Since we don’t know what your utility is doing, if it’s the culprit, you’ll need to show us some code if you want us … Read more
