  • Is there any way to "peek" at a file while it's uploading through HTTP onto a Windows box?

    - by iisystems
    I need to add a file upload function to an ASP.NET website and would like to be able to read a small portion of the file on the server while it's still uploading. A peek or preview type function so I can determine contents and give some feedback to the user while it is still uploading (we're talking about large files here). Is there any way to do this? I'm thinking worst case of writing a custom control which uploads only a fixed number of bytes of the file once chosen and then under the covers starts another upload of the full file. Not totally sure even this is possible, but I'm looking for a more elegant solution anyway... Thanks!

  • Does "Debug" invalidate ASP.Net MVC OutputCache?

    - by William Edmondson
    I have images stored in a database and am serving them from an MVC controller as "FileResult". If I run the MVC application from Visual Studio 2008 in debug mode and set a break point inside the controller method the debugger intercepts the call on every page refresh regardless of my "OutputCache" settings. Does the VS debugger invalidate the OutputCache or is there something else going on here? [OutputCache(Duration = 86400, VaryByParam = "id")] public FileResult Index(string id) { byte[] image; int imageId; int.TryParse(id, out imageId); using (var ctx = new EPEntities()) { var imageObj = (from images in ctx.Images where images.ID == imageId select images).FirstOrDefault(); image = imageObj.Image; } return new FileContentResult(image, "image/gif"); }

  • How can i monitor syslog messages in c# console app with TCP

    - by djerry
    Heya, In my application, i need to monitor all messages sent by syslog. I've tried with UDP, but after one message, i didn't respond anymore (no error, just no heads up anymore). And setting up a tcp server isn't really the solution either i think. Can anyone guide me to a solution where i can log messages form syslog with tcp (normally on port 514). Thanks in advance.

  • Defining a persistent static route on Mac OS X

    - by Charles Duffy
    How does one define a static route on MacOS X which persists through reboots? The only suggestion I've found on Google advises setting up a launchd service to run at boot, which seems like a horrible hack (does it survive a network restart without rebooting, for instance?) To set up the route I need temporarily, I can run the following: route add -net ${network} ${gateway} ${netmask} How would I make this persist?

  • Content server backups

    - by Dan Sosedoff
    What is the best way to backup data on content servers? For example, I have 15 servers that just have content, no applications running on it. Each server has a 250 GB hard drive. So, it's a pretty big amount of data. All the data have external access (via HTTP). So, the question is: what methodology is best in my case? The most useful method I know is cross-backup: when each server contains its own data and backup of one other server. But, there is significant reduction in total capacity. RAID?

  • Installing messaging software displays error 1324 invalid character

    - by llykke
    Trying to install Reuters Messaging software onto a windows 7 pc we receive the error message Error 1324: The folder path 'My Documents' contains an invalid character We've tried installing the application using the local admin account and the user account which is an AD account (roaming?). This user account has administrative rights (i.e. should be allowed to install applications). The users 'My Documents' folder is located on a network drive, where only the user has access. We've tried experimenting with the HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer\ User Shell Folders registry entries and setting them to a local position (i.e. C:\Users\Username\Documents) but this didn't resolve the error. We've also tried the following which was taken from a website I can't remember the name of: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem Select the NtfsDisable8dot3NameCreation entry and change the value to 0 Select the Win31FileSystem entry and change the value to 0 which didn't resolve the issue. Edit: This was also an issue when attempting to install the citrix native client necessary to run citrix application (*.ica extension). This made the same error box appear.

  • Monitor displays at 1024x768; scrolls screen for higher resolutions

    - by Matt
    I have a dual monitor setup. Normally, they both display at 1680x1050. They have been setup this way for about a year. I'm using Windows XP Professional 2003 x64 SP2. Today, out of nowhere, one of the monitors kicked back to a lower resolution. I was not playing with any configuration at the time.. in fact all I had done was close a window (maybe a browser). But the thing is that the resolution is still preserved partially by the fact that the screen will scroll when you move the mouse. So it's like looking through a 1024x768 window into a 1680x1050 world. The monitor itself does not appear to be damaged, because I also have it connected to my netbook (via KVM) and higher resolutions work fine. I tried uninstalling/reinstalling the drivers to no avail. System restore doesn't help either. I'm unsure of the exact ATI card I'm using.. Device Manager lists it as "Radeon X300/X550/X1050". There is no Catalyst Control Center software installed. I tried to install it, but there doesn't seem to be a way to install it by itself ... it forces you to install another driver, which breaks both of my displays, forcing me to go into safe mode and run system restore again. Any ideas? Thanks

  • Monotouch/C# version of "stringWithContentsOfUrl"

    - by Pselus
    I'm trying to convert a piece of Objective-C code into C# for use with Monotouch and I have no idea what to use to replace stringWithContentsOfUrl Should I use something like: HttpWebRequest request = (HttpWebRequest) WebRequest.Create("http://www.helephant.com"); HttpWebResponse response = (HttpWebResponse) request.GetResponse(); if (response.StatusCode == HttpStatusCode.OK && response.ContentLength > 0){ TextReader reader = new StreamReader(response.GetResponseStream()); string text = reader.ReadToEnd(); Console.Write(text); } Is that even safe to use in MonoTouch? Will it work for the iPhone?

  • OpenGL: Disable texture colors?

    - by Newbie
    Is it possible to disable texture colors, and use only white as the color? It would still read the texture, so i cant use glDisable(GL_TEXTURE_2D) because i want to render the alpha channels too. All i can think of now is to make new texture where all color data is white, remaining alpha as it is. I need to do this without shaders, so is this even possible?

  • iPhone - Have the keyboard slide into view from the right like when editing a note in Contacts

    - by Toon Van Acker
    Hello, I'm looking for a way to slide the keyboard into view from the right, like what happens in the Contacts application when you edit a note. My problem is that when I call [someTextView becomeFirstResponder] in viewWillAppear, the keyboard immediatly pops up with no animation. And when I call it in viewDidAppear, the view first slides in from the right (UINavigationController does the sliding), and then the keyboard slides in from the bottom. Is it possible to have the keyboard slide in from the right, together with the view?
