Delphi: play memorystream in wmp activex

由 走远了吗. 提交于 2019-12-11 07:49:11
问题 I'm new to this site and I hope someone can help me with my problem. I am using a Delphi language. And I would want to play a memorystream to windowsmediaplayer ActiveX. Is this possible? If it is, can someone give me a hint or something.. sample code maybe. Thanks. 回答1: I can't speak for Delphi 2009, but earlier version of Delphi didn't support this with the TMediaPlayer component. What you could do is write the MemoryStream to a temporary file, then have the TMediaPlayer load that file.

Upload Big ZipArchive-MemoryStream to Azure

由 左心房为你撑大大i 提交于 2019-12-11 04:32:58
问题 TL;DR : Is it possible to upload a big MemoryStream to Azure as chunks on the fly while zipping? I have files which get saved into a MemoryStream , I add these files to a ZipArchive in another MemoryStream. This MemoryStream I want to upload to an Azure-BlockBlob-Storage using blockBlob.UploadFromStream(zipMemoryStream); So far so good. The Problem now is, that the Zip-Archive might get bigger then 8GB which is a problem with the MemoryStream. Is it possible to upload parts from the memory

How can I load a memory stream into LibVLC?

问题 I want to play a media file from a memory stream using LibVLC like so: //Ideally it would go like this: LibVLC.MediaFromStream = new MemoryStream(File.ReadAllBytes(File_Path)); Of course this is a very oversimplified version of what I want but hopefully it conveys what I am looking for. The reason being that I want there to be a good amount of portability for what I'm doing without having to track file locations and such. I'd rather have a massive clump of data in a single file that can be

Can WCF MemoryStream return type be written to the Http Response object for downloading as an Excel file?

由 允我心安 提交于 2019-12-11 03:57:24
问题 I built a parsing application that reads xml files and populates an Excel workbook using the NPOI library. Originally, I had that as part of my .net web app and would get the MemoryStream from NPOI and write that to the Response object so the browser would download it. I've since moved the parsing to a WCF netTcp service hosted in a Windows Service. The communication works great, but when I return the MemoryStream from the WCF service and write it to the response, I get the following error:

ASP.NET C# upload MemoryStream content via FTPwebRequest issue

问题 This should be pretty straight forward, and uploading works. BUT when I open the uploaded file on the FTP server it shows binary data which is just some weird characters that look like this [][][][], and its the right file size. how do I add attributes or headers that that will say that this file is an XML? public bool ProcessBatch(MemoryStream memStream) { bool result = true; FTPaddress = DistributionResources.ftpServer; CompleteFTPPath = DistributionResources.ftpPath; request =
