  • ChangePassword control without provider

    - by EugeneK
    Hello, Is there a way to make ChangePassword control work without Membership provider? Like the same way Login control works through an Authenticate event, could I make this component to use my password changing function and then showing success view without me writing custom provider? Thanks, Eugene.

  • How to create a compiler in vb.net

    - by Cyclone
    Before answering this question, understand that I am not asking how to create my own programming language, I am asking how, using vb.net code, I can create a compiler for a language like vb.net itself. Essentially, the user inputs code, they get a .exe. By NO MEANS do I want to write my own language, as it seems other compiler related questions on here have asked. I also do not want to use the vb.net compiler itself, nor do I wish to duplicate the IDE. The exact purpose of what I wish to do is rather hard to explain, but all I need is a nudge in the right direction for writing a compiler (from scratch if possible) which can simply take input and create a .exe. I have opened .exe files as plain text before (my own programs) to see if I could derive some meaning from what I assumed would be human readable text, yet I was obviously sorely disappointed to see the random ascii, though it is understandable why this is all I found. I know that a .exe file is simply lines of code, being parsed by the computer it is on, but my question here really boils down to this: What code makes up a .exe? How could I go about making one in a plain text editor if I wanted to? (No, I do not want to do that, but if I understand the process my goals will be much easier to achieve.) What makes an executable file an executable file? Where does the logic of the code fit in? This is intended to be a programming question as opposed to a computer question, which is why I did not post it on SuperUser. I know plenty of information about the System.IO namespace, so I know how to create a file and write to it, I simply do not know what exactly I would be placing inside this file to get it to work as an executable file. I am sorry if this question is "confusing", "dumb", or "obvious", but I have not been able to find any information regarding the actual contents of an executable file anywhere. One of my google searches Something that looked promising EDIT: The second link here, while it looked good, was an utter fail. I am not going to waste hours of my time hitting keys and recording the results. "Use the "Alt" and the 3-digit combinations to create symbols that do not appear on the keyboard but that you need in the program." (step 4) How the heck do I know what symbols I need??? Thank you very much for your help, and my apologies if this question is a nooby or "bad" one. To sum this up simply: I want to create a program in vb.net that can compile code in a particular language to a single executable file. What methods exist that can allow me to do this, and if there are none, how can I go about writing my own from scratch?

  • How does bridged networking work?

    - by agz
    How does bridged networking work? I have looked through the virtualbox manuals but nothing extremely technical came up (It was just a generic gloss over of the topic) How does it assign a different ip to the virtual machine but uses the same network card? Why does this different ip (I found using ip addr under linux) not show up under the "attached devices section" of my router but I can port forward to it? How come if I connect to a password protected wifi network, it does not require me to enter my password? Is this multihoming?

  • Audio input problem in Ubuntu 9.10

    - by Andrea Ambu
    My audio input is a mix of my mic output and my sound card output. I'd like it to be just my mic output. I was able to do so in Ubuntu 9.04 but the interface is 9.10 is totally changed and I tried every my creativity was able to think. It's really annoying when talking to other people over the internet because they keep hearing their voice back. I'm not sure I explained it in clear way so I'll give you an example: What I do: I put an mp3 on play or a video on youtube then open a recorder and start to talk on my mic. What happens: both my voice and audio from mp3/youtube get reordered, even if I put headphones volume to 0 (via hardware). What I'd like to happen: Only my voice should be recorded. I'm sure I'm missing some technical term, but that's the problem and I'd like to solve it in Ubuntu 9.10, any idea?

  • failsafe jQuery code

    - by David
    Can anyone explain what the jquery documentation is exactly referring to with this statement: "the argument to write failsafe jQuery code using the $ alias, without relying on the global alias" when referring to using the following: jQuery(function($) { }); I have been using jquery for a while now so understand what this code is doing to a certain extent but the phrase used in the documentation about writing failsafe jquery code puzzles me and i am unsure whether it is important or not.

  • Backup Exec 12.5 or 2010? [closed]

    - by Chris Thorpe
    Backup Exec 2010 has just dropped, and I'm about to implement a new BEWS infrastructure, complete with CALs and new central servers. When I specced this up last year, I ignored 2010 and focused on Backup Exec 12.5, since it's a mature product. In previous experience, major released of BE had numerous technical issues and seemed to improve significantly at the first service pack. However, our refresh cycle on the backup infrastructure is slow, the main driver usually being lack of support for some new server type (in this case, ESX has driven our current upgrade need). With this in mind, I'm wondering if Backup Exec 2010 should be my first choice, as it'll last longer under current support than 12.5, which will approach EOL soon. Has anyone got any perspective they could add to this? Right now, I'm leaning towards biting the bullet and going with 2010.

  • running jython bytecode using java

    - by noamtm
    It looks like I'm missing something. When using Jython to run my Python code in Java, Java bytecode files are generated (test.py - [email protected]). Can I run these classes directly using java? In other words, I want to make this: $ java test@py [additional cp args] work. The intent: writing Python code and not having to give away source code.

  • Ubuntu VPS - email and webserver

    - by xZero
    I have a VPS based on Ubuntu, it has installed whole LAMP, everything needed for a web server and it works perfectly, but I'm still not able to configure it as a mail server.... I have configured MX record for my domain mail.mydomain.com and this part is OK, I also installed Postfix, Dovecot and Roundcube, configured it using this tutorial: http://ubuntuguide.org/wiki/Mail_Server_setup And after hours of configuring it doesn't work. I have experience with Linux and web hosting, but I successfully configured mail server once in past on Debian 6, and that with help from there. When I try to send email to me my gmail says: Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the server for the recipient domain mydomain.com by dc147738a1117e4c12273.mydomain.com. [MY_SERVER_IP]. The error that the other server returned was: 554 5.7.1 <[email protected]>: Relay access denied Also I have Webmin control panel which works perfectly, how to configure postfix and dovecot from there? Thanks in advance.

  • Why would a server not send a SYN/ACK packet in response to a SYN packet

    - by codemonkey
    Lately, we've become aware of a TCP connection issue that is mostly limited to mac and Linux users who browse our websites. From the user perspective, it presents itself as a really long connection time to our websites (11 seconds). We've managed to track down the technical signature of this problem, but can't figure out why it is happening or how to fix it. Basically, what is happening is that the client's machine is sending the SYN packet to establish the TCP connection and the web server receives it, but does not respond with the SYN/ACK packet. After the client has sent many SYN packets, the server finally responds with a SYN/ACK packet and everything is fine for the remainder of the connection. And, of course, the kicker to the problem: it is intermittent and does not happen all the time (though it does happen between 10-30% of the time) We are using Fedora 12 Linux as the OS and Nginx as the web server.

  • Build an Xcode project on a Linux machine

    - by d11wtq
    Without writing a GNUmakefile by hand, do any tools exist that understand Xcode projects and can build then directly against GNUstep, thus simplifying (slightly) the work required to keep projects functional under Cocoa/Mac and GNUstep/Linux? Basically, is there an xcodebuild style app for Linux? I looked at pbtomake a few weeks ago but it seems to be a dead project.

  • What reasons have people had to write their own classloader

    - by montyontherun
    I was recently asked in an interview about the order in which classloaders are called when a class is loaded. Unfortunately I've never had the need to write my own classloader so at the time was unfamiliar with the intricacies of classloading. This got me wondering, what reasons are their to write your own classloader. So that's my question: What scenarios have people faced which required the need to writing their own classloaders?

  • Creating Read-only logs with python

    - by Travis
    I am writing a python script that needs to make a log entry whenever it's invoked. The log created by the script must not be changeable by the user (except root) who invoked the script. I tried the syslog module and while this does exactly what I want in terms of file permissions, I need to be able to put the resulting log file in an arbitrary location. How would I go about doing this?

  • Generic Property in C#

    - by ml123
    Hi, I'm not quite sure how to do that, but what I would like to do is to create a special type of property that will perform specific tasks at the get and set, and will be defined on generic type. For example, when writing this: MyProp<String name; a pre-defined get and set will be performed on the string value. How can that be done? Thanks!

    Hello everyone, I am writing a piece of software in C++ RAD studio 2010 and got a question about TreeView. Is it possible to use multicolor text in a TTreeView component? I could not find a easy way but to implement custom drawing which seems to be weird nowadays. Are there any straight-forward ways or maybe additional components that can do it for me?
