  • C# (ASP.Net) Linking selection values to constants in Codebehind

    - by jasonvogel
    ASPX Code <asp:RadioButtonList ID="rbServer" runat="server" > <asp:ListItem Value=<%=ServerDeveloper%>> Developer </asp:ListItemv <asp:ListItem Value="dev.ahsvendor.com"> dev.test.com</asp:ListItem> <asp:ListItem Value="staging.ahsvendor.com"> staging.test.com</asp:ListItem> </asp:RadioButtonList> ASPX.CS - Codebehind const string ServerDeveloper = "developer"; ASPX Error: Code blocks are not supported in this context. Question: So what is the correct way to tie an dropdown/radio buttion/... ASPX value to a constant that is shared with the CodeBehind code? I know that I could do rbServer.Add.Item("developer") [from the CodeBehind], but is there a way to achieve it from the Presentation side of things?

  • What next generation low level language is the best bet to migrate the code base ?

    - by e-satis
    Let's say you have a company running a lot of C/C++, and you want to start planning migration to new technologies so you don't end up like COBOL companies 15 years ago. For now, C/C++ runs more than fine and there is plenty dev on the market for it. But you want to start thinking about it now, because given the huge running code base and the data sensitivity, you feel it can take 5-10 years to move to the next step without overloading the budget and the dev teams. You have heard about D, starting to be quite mature, and Go, promising to be quite popular. What would be your choice and why?

  • Django AND .htaccess rewrites/redirects, is this possible?

    - by Infinity
    Is it possible to have Apache htaccess rewrites take effect before it hits django? For example so I can redirect iPhone users to a completely different domain without even hitting django. We're using apache2 with mod_wsgi and the apache vhost looks like this: <VirtualHost *:80> DocumentRoot /usr/local/www/site/static Alias /css/ /usr/local/www/site/static/css/ Alias /js/ /usr/local/www/site/static/js/ Alias /img/ /usr/local/www/site/static/img/ Alias /flash/ /usr/local/www/site/static/flash/ <Directory /usr/local/www/site/static> AllowOverride All Order allow,deny Allow from all </Directory> WSGIDaemonProcess mallorca-site threads=15 WSGIScriptAlias / /usr/local/www/site/config/dev/dev.wsgi </VirtualHost> Thanks

  • I'm a PHP programmer, how easy will it be to "master" c++?

    - by ThinkingInBits
    I've been a PHP programmer for 8 or so years, I'm familiar with OOP and try to consider best practices whenever programming. I would like to pick up C++ to possibly enter the 'game development' field, where now I'm doing web dev. I'm not a school person, but was wondering what people think about self-taught math to complement learning c++ for game dev. The last math course I took was algebra 2. Should I start delving myself into pre-calculus? Are there any other suggestions you may have to ease the process?

    Following this SO question, I'm trying to "truncate" all tables related to a certain django application using the following raw sql commands in python: cursor.execute("set foreign_key_checks = 0") cursor.execute("select concat('truncate table ',table_schema,'.',table_name,';') as sql_stmt from information_schema.tables where table_schema = 'my_db' and table_type = 'base table' AND table_name LIKE 'some_prefix%'") for sql in [sql[0] for sql in cursor.fetchall()]: cursor.execute(sql) cursor.execute("set foreign_key_checks = 1") Alas I receive the following error: C:\dev\my_project>my_script.py Traceback (most recent call last): File "C:\dev\my_project\my_script.py", line 295, in <module> cursor.execute(r"select concat('truncate table ',table_schema,'.',table_name,';') as sql_stmt from information_schema.tables where table_schema = 'my_db' and table_type = 'base table' AND table_name LIKE 'some_prefix%'") File "C:\Python26\lib\site-packages\django\db\backends\util.py", line 18, in execute sql = self.db.ops.last_executed_query(self.cursor, sql, params) File "C:\Python26\lib\site-packages\django\db\backends\__init__.py", line 216, in last_executed_query return smart_unicode(sql) % u_params TypeError: not enough arguments for format string Is the % in the LIKE making trouble?

  • HTML5 video element non-seekable when using Django development server

    - by Ory Band
    Hey everyone. I've got a Django app serving a webpage with an HTML5 element. There's a wierd "feature", turning the video element to be non-seekable: video.seekable returns a timeRanges object with length=0, whereas it should be length=1. This means I can't edit the video. JavaScript can't do anything either. The thing is, when I upload the problematic webpage, statically - no Django, just plain HTML/JS/CSS - to my website for testing, it works fine - length=1. However, if I try to serve the same static page on my Django dev server still gives the same problem. I am using Django's static serving for dev/debug purposes - Do you have any idea what is causing this, or how can I fix it? Thanks.

  • bash check if value in list

    - by tkoomzaaskz
    I've got a script with a variable taken from command line parameters. I want to check if it's value is one of dev, beta or prod. I've got following code snippet: #!/usr/bin/env bash ENV_NAME=$1 echo "env name = $ENV_NAME" ENVIRONMENTS=('dev','beta','prod') if [[ $ENVIRONMENTS =~ $ENV_NAME ]]; then echo 'correct' exit else echo 'incorrect' exit fi When I run my script, it doesn't matter which parameters I pass: ./script.sh beta or ./script.sh or ./script.sh whatever, I always get correct echoed. What is wrong in my script?

  • How can I write an autostarting dock app for the Mac?

    - by TreeUK
    I have an application I'd like to build that starts when you start the mac and will appear in the dock. I have some experience with Objective-C and iPhone dev but none with Mac dev, I'm also a PC user normally so I'm not au fait with the norms of Mac usage. Any guidance here is appreciated. How do you get an application to autostart? Can you run an app in the tray bar? (with the clock etc in) or do apps only run in the dock?

  • Is there a jquery clone of ext.js' toolbar?

    - by fbuchinger
    I'm looking for a jquery equivalent of ext.js' toolbar (http://dev.sencha.com/deploy/dev/examples/menu/menus.html). To be more precisely, my requirements are the following: the toolbar should consist of iconic and textual buttons and dropdown widgets buttons should either trigger actions directly or open submenus buttons and submenus should have the ability to remember the last selected state buttonsets should group multiple buttons and only allow one of them to be active In short words, I'm looking for a real toolbar in jquery and not for some modified site menu. I experimented with the button/buttonset/menu widget in jquery ui 1.9m2, but found its IE performance rather poor. It also felt awkward to combine these isolated widgets into a logically connected toolbar. Does anyone know of a better jquery toolbar plugin?

  • Is there a way to have a bit bucket pointer? (C/C++)

    - by Crazy Chenz
    Is there a way to have a bit bucket pointer? A lot of IO (specifically input related) system calls return data to a buffer of a specific size. Is there a trick or way to make a sorta bit bucket pointer, so I can accept any amount of data that will be thrown away. Doing something like "char tmp[INT_MAX]" is crazy. The behavior I am looking for is something like /dev/null, only in a pointer world. Not to hopeful on this.... just curious. Thanks, Chenz UPDATE: Perhaps mmap-ing /dev/null. Forgot about that when I asked the question.

  • Robust way to display an image with one fixed dimension

    - by DomingoSL
    Lets say that we have an image uploaded by the user, the upload script limits the mb but not the image size (so could be any proportion, 600X200,200X350, and so...). Im already showing this image in one part on my site using the twitter bootstrap image handler written on css, thats good for a profile picture, the problem is that now I want that image to be a cover (like facebook/twitter cover image), my site is responsive so the width of the cover is 900px or 100% if the screen resolution is less than 900px wide. The height is always fixed to 200px. So I know there is a way to control the correct image display using CSS (maybe with jquery too) but Im not a front-end dev, Im a php dev and I dont want to use server side scripts for doing this. So im looking for suggestions or pieces of codes (css, javascript) to start with, I belive that it have to be an already made solution for this, but I dont find any on google. Thanks for any advice!

  • Version control PHP Web Project

    - by Adam Lerman
    We have a php project that we would like to version control. Right now there are three of us working on a "Dev" version of the project that all have our Eclipse linked to it with just an external folder, and thus no version control. What is the right way, and what is the best way, to version control this (not necessarily the same I dont think) We have a SVN set up but just need to find a good way to check in and check out that lets us test on the dev server. Any ideas?

  • HTTP server that handles requests through IO devices?

    - by StackedCrooked
    This question can probably only be answered for Unix-like systems that follow the "everything is a file" idiom. Would it be hard to create a web server that mounts local devices for handling http traffic? It would enable a program to read raw http requests from /dev/httpin (for example) and write the responses to /dev/httpout. I think this would be nice because it would allow me to create a web server from any programming language that is capable of handling IO streams. I don't really know where to start on this. Any suggestions on how to setup such a system?

  • How can one configure Hudson to integrate with Sventon?

    - by mark
    Dear ladies and sirs. Hudson ver. 1.353 Sventon ver. 2.14 I just cannot figure out how to configure Hudson to work with Sventon. It seems that the path format that Hudson expects from Sventon is not the format used by Sventon. Any ideas? Thanks. UPDATE Given an SVN repository with the name of windows, the Sventon URL path to the repository is http://dev-builder:8080/svn/repos/windows/list/ However, Hudson expects something like http://dev-builder:8080/svn/repobrowser.svn?name=windows Can anyone explain how this should be configured?

  • Apache RewriteRule not rewriting as expected

    - by Jeff
    Can you any one see anything wrong with the following apache rewrite rule: This is in my .htaccess file inside a folder called "text" a subdirectory of localhost/lombardpress I have the following rule Options +FollowSymlinks RewriteEngine on RewriteRule ([^/]+) /textdisplay.php?fs=$1 [NC] I was expecting this input: http://localhost/lombardpress-dev/text/lectio1 to rewrite to this: http://localhost/lombardpress-dev/text/textdisplay?fs=lectio1 But instead I get a 404 error. The requested URL /textdisplay.php was not found on this server. It looks to me like the RewriteRule has re-written the address but not as I intended - so there must be something wrong with my regular expression. Let me know if I can provide further information.

  • Developing for Windows 6.5

    - by j-t-s
    Hi All I have just got a new company mobile and would like to begin developing apps for the HTC HD2 Mobile Phone. However, when I downloaded Microsoft Windows Phone Developer Tools, it pretty much said right at the end of installation that "Setup could not install correctly", and I clicked on "more", and it said "Silverlight 4.0 could not install correctly". So, the fact that Windows Phone Dev Tools couldn't install completely was because of this Silverlight 4 that couldn't install! Has anyone had the same problems, if so, how did you resolve this issue (if you did)? And... Is there another way to develop applications for mobile phones running the Windows Operating System other than XNA and Windows Dev Tools? Even better... Could it be done simply using the current Visual Studio Express Edition I already have? Thanks All

  • Aliasing localhost in Tomcat

    - by Saurabh
    I have a web application "quicker" deployed in Tomcat5.5 version. Usually, I run this application by using url, localhost/quicker and it loads the index.jsp file which is the home page of application. I would like same application to be run using url, www.local.dev.mydomain.com/quicker. Would it be possible by doing some configuration in server.xml or some other place? One way of doing this is could be, modify hosts file in windows as - # 127.0.0.1 localhost 127.0.0.1 www.local.dev.mydomain.com But, I want to this in tomcat manner if possible.

  • Why are some programs writing on stderr instead of stdout their output?

    - by Zagorax
    I've recently added to my .bashrc file an ssh-add command. I found that ssh-add $HOME/.ssh/id_rsa_github > /dev/null results on a message "identity added and something else" every time I open a shell. While ssh-add $HOME/.ssh/id_rsa_github > /dev/null 2>&1 did the trick and my shell is now 'clean'. Reading on internet, I found that other command do it, (for example time). Could you please explain why it's done?

  • Java SWT - dissolve (fade) from one image to the next.

    - by carillonator
    I'm pretty new to Java and SWT, hoping to have one image dissolve into the next. I have one image now in a Label (relevant code): Device dev = shell.getDisplay(); try { Image photo = new Image(dev, "photo.jpg"); } catch(Exception e) { } Label label = new Label(shell, SWT.IMAGE_JPEG); label.setImage(photo); Now I'd like photo to fade into a different image at a speed that I specify. Is this possible as set up here, or do I need to delve more into the org.eclipse.swt.graphics api? Also, this will be a slide show that may contain hundreds of photos, only ever moving forward (never back to a previous image)---considering this, is there something I explicitly need to do in order to remove the old images from memory? Thanks!!

  • bandwidth throttling C linux

    - by bob moch
    hi im currently creating a function to create a sleep time i can pause between packets for my port scanner im creating for personal/educational use for my home network. what im currently doing is opening /proc/net/dev and reading the 9th set of digits for the eth0 interface to find out the current packets being set and then reading it again and doing some math to figure out a delay to sleep between sending a packet to a port to identify it and fingerprint it. my problem is that no matter what throttle % i use it always seems to send the same rate of packets. i think its mainly my way of mathematically creating my sleep delay. edit:: dont mind the function declaration and the struct stuff all im doing is spawning this function in a thread and passing a pointer to a struct to the function, recreating the struct locally and then freeing the passed structs memory. void *bandwidthmonitor_cmd(void *param) { char cmdline[1024], *bytedata[19]; int i = 0, ii = 0; long long prevbytes = 0, currentbytes = 0, elapsedbytes = 0, byteusage = 0, maxthrottle = 0; command_struct bandwidth = *((command_struct *)param); free(param); //printf("speed: %d\n throttle: %d\n\n", UPLOAD_SPEED, bandwidth.throttle); maxthrottle = UPLOAD_SPEED * bandwidth.throttle / 100; //printf("max throttle:%lld\n", maxthrottle); FILE *f = fopen("/proc/net/dev", "r"); if(f != NULL) { while(1) { while(fgets(cmdline, sizeof(cmdline), f) != NULL) { cmdline[strlen(cmdline)] = '\0'; if(strncmp(cmdline, " eth0", 6) == 0) { bytedata[0] = strtok(cmdline, " "); while(bytedata[i] != NULL) { i++; bytedata[i] = strtok(NULL, " "); } bytedata[i + 1] = '\0'; currentbytes = atoi(bytedata[9]); } } i = 0; rewind(f); elapsedbytes = currentbytes - prevbytes; prevbytes = currentbytes; byteusage = 8 * (elapsedbytes / 1024); //printf("usage:%lld\n",byteusage); if(ii & 0x40) { SLEEP += (maxthrottle - byteusage) * -1.1;//-2.5; if(SLEEP < 0){ SLEEP = 0; } //printf("sleep:%d\n", SLEEP); } usleep(25000); ii++; } } return NULL; } SLEEP and UPLOAD_SPEED are global variables and UPLOAD_SPEED is in kb/s and generated via a speedtest function that gets the upload speed of my computer. this function is running inside a POSIX thread updating SLEEP which my threads doing the socket work grab to sleep by after every packet. as testing instead of only doing the ports i want to check i make it do all the ports over and over again so i can run dstat on a machine to check bandwidth and no matter what bandwidth.throttle is set to it always seems to generate the same amount of bandwidth to the dstat machine. the way i calculate how much i "should" throttle by is by finding the maximum throttle speed which is defined as maxthrottle = upload_speed * throttle / 100; for example if my upload speed was 1000kb/s and my throttle was 90 (90%) my max throttle would be 900kb/s from there it would find the current bytes sent from /proc/net/dev and then find my sleep time via incrementing or decrementing it via sleep += (maxthrottle - bytesysed) * -1.1; this should in theory increase or decrease the sleep time based on how many bytes used there are. the if(ii & 0x40) statement is just for some moderation control. it makes it so it only sets sleep to a new time every 30-40 iterations. final notes: the main problem is that the sleep timer does not seem to modify the speed of packets being set. or maybe its just my implementation because on a freshly restarted machine where /proc/net/dev has low numbers of bytes sent it seems to raise the sleep timer accordingly on my 60kb/s upload machine (ex if i set the throttle to 2 it will incline the sleep timer until network bandwidth out reaches the max bandwidth threshold, but when i try running it on a server which as been online forever it doesnt seem to work as nicely if at all. if anyone can suggest a new method of monitoring the network to adjust a sleep delay then let me know or if anyone sees a flaw in my code. thank you.
