  • Babel Obfuscator: Sample effective post build event for free version

    - by JL
    Does anyone have a sample post build event for Babel Obfuscator I can just copy and paste into my .net assembly release build configuration? The documentation for Babel is 54 pages long, and unfortunately doesn't come with any real world samples on how to use it with Visual Studio integration. Failing that , is there a free obfuscator out there that integrates well with VS 2008 post build, so that it will obfuscate the release DLL during each new build. I was using Eazfuscator which broke since they released version 2.8. Thank you

  • Tips for transitioning from Visual Basic to Xcode

    - by Cyclone
    I've been programming in VB.net for a while now, and I finally got access to a mac to make ipod apps. What are some useful sites, videos, etc. that could help me get used to Objective C and the Xcode IDE? I've stumbled upon the samples on the apple dev site, but none of them really give good examples which I could learn the syntax of the language from. Thanks for the help, Objective C is really a big change from VB.net!

  • KML Layers Cursor CSS - Google Maps API v3

    - by Douglas
    I've run into a small problem with the semi-new KML Overlay functionality with Google Maps API v3, wherein while I am able to use "suppressInfoWindows: true;", the cursor still appears as though the overlay(s) are clickable. Is there a way at this time to change the css on the overlay(s) so that the cursor is the default cursor, so that they are purely visual, and don't confuse the user? The current demo version can be viewed here: http://dougglover.com/samples/finalProduct/ Any assistance is greatly appreciated.

  • How to supress Powershell window when using the -File option

    - by guillermooo
    I'm calling Powershell like so: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -noprofile -noninteractive -nologo -file "C:\Users\dummy\Documents\dev\powershell\samples\test.ps1" I'm calling it from a python script, but the same problem can be observed if called via a shortcut. I thought the -NonInteractive flag would cause Poweshell to execute in a hidden window, but it doesn't. Is there a way of supressing the console window when calling Powershell from an external application? Solution based on Johannes Rössel suggestion st_inf = subprocess.STARTUPINFO() st_inf.dwFlags = st.inf.dwFlags | subprocess.STARTF_USESHOWWINDOW Popen(["notepad"], startupinfo=st_inf)

  • What is the exact problem with multiple inheritance?

    - by Totophil
    I can see people asking all the time whether multiple inheritance should be included into the next version of C# or Java and C++ folks, who are fortunate enough to have this ability, say that this is like giving someone a rope to eventually hang themselves. What’s the matter with the multiple inheritance? Are there any concrete samples?

  • Anyone know of a good open source spam checker in java or c#?

    - by Spines
    I'm creating a site where users can write articles and comment on the articles. I want to automatically check to see if a new article or comment is spam. What are good libraries for doing this? I looked at bayesian classifier libraries, but it seems that I would have to gather a large amount of samples and classify them all as spam or not spam myself... I'm looking for something that can hopefully just tell me right out of the box.

  • How to style a code block to make all the colours look pretty like my IDE and here in stackoverflow?

    - by BritishDeveloper
    When putting code samples in my blog I would like the code to have all the appropriate colours. How can I do that? Basically if I write: foreach (ListItem item in items) { item.Text = "something"; } I want it to appear in the correct colours like it does in my Visual Studio or here at stack*overflow*. I'm bored of styling the colours of each key word manually. Is there a pre-existing javascript library I can use?

  • Django database caching

    - by hekevintran
    The object user has a foreign key relationship to address. Is there a difference between samples 1 and 2? Does sample 1 run the query multiple times? Or is the address object cached? # Sample 1 country = user.address.country city = user.address.city state = user.address.state # Sample 2 address = user.address country = address.country city = address.city state = address.state

    I get confused with some terms while reading MSDN documents and code samples. What are callbacks in C#? In particular, what are synchronous and asynchronous callbacks ? Please explain these from a layman's point of view. Also, please explain the IAsyncResult interface. How can we implement it? (with very simple example) Thanks in advance.

  • What are guard methods/classes?

    - by Paul Sasik
    i just noticed the guard method/class mentioned in this question and i don't really get the concept from the answers. And alas, Jon Skeet's link to an MS site never loaded. A few quick Google searches seemed to yield only products, not software engineering concepts. Any explanation and/or samples would be appreciated. (Especially from the .Net side of things.)

  • getting vbulletin captcha image with curl

    - by ermac2014
    hi I need to download Vbulletin captcha images on my HDD "from vbulletin register page" using curl and PHP. I really need to get samples of captcha images from several VBulletin boards. I'm collecting these samples for research purposes. anyway, here is what I done with curl till now. 1- download register.php page. 2- parse the downloaded page to get captcha image url. 3- download that image. now I have done step 1 and 2 correctly. but in step 3 when I try to download the captcha image I don't get the captcha. I just get either a very tiny blank gif picture. or I get a png picture with vbulletin word on it. I really don't know what i'm doing wrong. I tried to output the html and push it to the browser the image shows correctly. but thats not what I want. I want to download the image and save it on my HDD. here are some codes I've been working on: //get contents with curl function get_content($url) { $theString = parse_url($url); $cookieName = $theString['host']; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url."register.php"); curl_setopt($ch, CURLOPT_REFERER, $url."register.php"); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; MSIE 7.0; Windows NT 6.0; en-US)'); curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies/cookie.txt"); //saved cookies curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies/cookie.txt"); //saved cookies curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); $string = curl_exec ($ch); //print_r(curl_getinfo($ch)); curl_close ($ch); return $string; } //vbulletin main page $url = 'http://blavbulletin.com/'; //get the page $results = get_content($url); if (preg_match_all('/<img[^>]*id\=\"imagereg\"[^>]*src\=\"([^\"]*)\"[^>]*>/s', $results , $captchaimages)) { $captcha = $captchaimages[1][0]; echo "<img src='$url"."$captcha'>"; //when echoed the pic shows correctly //now get the pic $file = get_content("$url"."$captcha"); //save the pic on HDD file_put_contents("captcha.jpg", $file); } any help would be appreciated.. regards,

  • Further explanation of IntentService

    - by rayman
    Hi all, I was trying to get the purpose of the IntentService, and when should I use it? I tried to understand from the API, but not enough details on that one. Is there any analogy between this and running long-task on a working thread? Any further explanation and samples on why I would use IntentService would be very welcome. Thanks, ray.

However I want to create dataset programatically like sample code below. And I want to bind it. Dim ds As New DataSet DB_Gateway.myDataSet("select * from users", ds, "users") How can I do it?
