Open Directory Using CreateFile

我的未来我决定 提交于 2019-12-06 03:37:17
I am trying to utilize the CreateFile function to access directory information. I am recieving a win32 error code of 5 however, which means Access Denied. Please advise. CreateFile(path, GENERIC_READ, FILE_SHARE_READ, IntPtr.Zero, OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, IntPtr.Zero); This is the call being made, and as noted in the documentation the 'FILE_FLAG_BACKUP_SEMANTICS' is being used. The DLL import seems to be working fine and looks like the following: [DllImport("kernel32.dll", SetLastError = true)] public static extern IntPtr CreateFile(string filename, uint desiredAccess, uint

Can images be read from an iPhone programmatically using CreateFile in Windows?

南楼画角 提交于 2019-12-06 03:31:08
问题 When an iPhone is connected to a Win7 computer, the images can be viewed using Explorer (and the open file dialog of my app). However, the file location does not contain a drive letter. For example Computer\Apple iPhone\Internal Storage\DCIM\800AAAAA\IMG_0008.JPG instead of E:\DCIM\800AAAAA\IMG_0008.JPG which is common of sdcards, usb drives, etc... I've tried using CreateFileW to read images from an iPhone but it fails with '(Error Code: 3) The system cannot find the path specified.' I've

Closed. This question is off-topic . It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . I'm trying to use CreateFile function, but it does not go as planned. I did a simple test code : #include <Windows.h> #include <iostream> #include <tchar.h> using namespace std; int main() { HANDLE hFile; hFile = CreateFile(_T("test.txt"), GENERIC_READ, NULL, NULL, OPEN_EXISTING, NULL, NULL); if (hFile == INVALID_HANDLE_VALUE) { cout << GetLastError() << endl; Sleep(2000); return EXIT_FAILURE; } return EXIT

Creating a Random File in C#

我只是一个虾纸丫 提交于 2019-12-03 10:55:17
问题 I am creating a file of a specified size - I don't care what data is in it, although random would be nice. Currently I am doing this: var sizeInMB = 3; // Up to many Gb using (FileStream stream = new FileStream(fileName, FileMode.Create)) { using (BinaryWriter writer = new BinaryWriter(stream)) { while (writer.BaseStream.Length <= sizeInMB * 1000000) { writer.Write("a"); //This could be random. Also, larger strings improve performance obviously } writer.Close(); } } This isn't efficient or

Create file with command line in Node

我的梦境 提交于 2019-12-03 09:55:49
So I'm attempting to do this Node.js tutorial , and it says to create three .js files from the command line. touch server.js client.js test.js Except I get the following error: 'touch' is not recognized as an internal or external command, operable program or batch file. Not sure what is wrong here. I've installed Node.js as well as npm and browserify. I've created the package.json file correctly. I suppose I could go into the project directory, right click and make a new file that way, but that defeats the purpose doesn't it? What is the actual command to create a new file in the command line?
