问题 I need a application to copy text and images form PowerPoint to Word. I use this libraries: Microsoft.Office.Interop.PowerPoint and Microsoft.Office.Interop.Word. The text s easy to transfer, but when I find in PowerPoint a shape containing only a image, it show this error: " A generic error occured GDI+ ", at this part of code: foreach (PowerPoint.Shape shape in slide.Shapes) { if (shape.HasTextFrame != MsoTriState.msoTrue){ shape.Copy(); Image img = (Image)Clipboard.GetData(DataFormats

问题 I'm trying to write a simple client/server in Python using a TCP socket but I can't seem to figure out why the file is not transferring. Client: import socket HOST = '' #server name goes in here PORT = 3820 socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM) socket.connect((HOST,PORT)) fileToSend = open('myUpload.txt', 'rb') while True: data = fileToSend.readline() if data: socket.send(data) else: break fileToSend.close() print 'end' socket.close() exit() The print end is just to tell

问题 Suppose I have a device that knows the name of a file they want to download from my server. How can I transfer said file to that device without giving the device access to the file system? For example, suppose I have a page ping.php which receives a get request for "something.zip" ping.php knows the location of something.zip (somewhere on the server's file system), but I can't allow the user access to the file system, or allow them to know the location of the file (it even needs to be hidden

问题 Update Trying to post the file to transloadit using the FileTransfer plugin using the following code var uri = encodeURI("https://api2-eu-west-1.transloadit.com/assemblies"); var options = new FileUploadOptions(); options.fileKey = "file"; options.fileName = filepath.substr(filepath.lastIndexOf('/') + 1); var params = new Object(); params.auth =new Object(); params.auth.key ="***************" ; options.params = params; var ft = new FileTransfer(); ft.upload(filepath, uri, win, fail, options);

问题 So, I've got some generic data in a file. My quest is simple: store that in a field in the database, and retrieve it again later back in to a file. I don't care how it is stored, nor what methods used to transfer it back and forth (but if i can contain it to a plpgsql function or two, that would be an awesome bonus). But it must come back to a file exactly the same as it was entered, bit for bit. I cannot guarantee that it wouldn't contain any special characters, and the data varies in size

问题 I'm currently writing a server-client application that need to transfer some file to work. I'm using this method: client: file_to_send = raw_input(">") try: f = open("./sent_files/" + file_to_send, "rb") except IOError, e: print ">error: ", e break data = xmlrpclib.Binary(f.read()) if s.receive_file(file_to_send, data): print ">file correctly sent" server: def receive_file(self, name, arg): with open("./sampletest/"+name, "wb") as handle: handle.write(arg.data) But how can I do the opposite

问题 I have problem with my transfer files application .. everything looks great and works the way it should be .. but then I discovered that some pieces of the sent file is corrupted. Like when I send a video file (.MP4) it sent successfully but when I play it some frames of it got corrupted like in the snapshot picture .. I played the source Mp4 file and the picture was so perfect and never looked like in that snapshot picture. So here's my code .. I'm confused now about using fs.Seek .. someone

问题 See my other QUESTION. I've successfully set up a simple file transfer, but I've noticed that trying to echo anything on the page corrupts the file, making it unopenable. Here's the code: $filename = $_GET['filename']; $dir = "C:/Users/Me/Desktop/"; $file = realpath($dir . $filename); //echo "$filename</br>$dir</br>$file"; if (file_exists($file)) { header('Content-Disposition: attachment; filename="'.basename($file).'"'); header('Content-Type: application/octet-stream'); header('Content
