• How to prompt for username and password entry in C# / SQL ASP.NET web app?

  - by salvationishere

  How do I prompt for username and password in my C#/SQL web application? This was developed in VS 2008 on a 32-bit XP. The current connection string I'm using in my web.config file is: <add name="AdventureWorksConnectionString2" connectionString="Data Source=SIDEKICK;Initial Catalog=AdventureWorks;Persist Security Info=false; " providerName="System.Data.SqlClient" /> When I select Basic Authentication it pops up the warning: "The authentication option you have chosen results in passwords being sent over the network without data encryption..." How do I choose this authentication method and still send passwords over securely? So essentially I am looking for the most secure authentication method but that still requires users to input password?

• How to check the compatibility between my program and the .net framework versions?

  - by Jack

  Hi all I am writing a program which is targeted to run on .net framework 2.0. I have chosen 2.0 in my VS project. It runs fine on my machine (mine has 2.0 SP2), so there is no compile error. but when I tried to run it on another machine (only with 2.0, no sp), it cannot run. I am aware that I used some method which is supported by 2.0 but only with 2.0 SP2. .net framework 2.0 SP2 seems not being listed in VS IDE, that's why VS cannot give me any warning when I compiled it on my machine. How can I easily check the compatibility of my codes with .net framework 2.0 SP2? or I just have to look at msdn to check every method I have used??? thanks

• Localizing a JSF 1.2 application with UTF-8 resources

  - by Filini

  (WARNING: this is my first java application, coming from .NET, so don't bash me if I write too much garbage) I'm developing a simple JSF 1.2 web application which should support Russian, Chinese, and other languages outside ISO 8859-1, which is automatically used in Properties.load(). Is there a way to use the Properties loaded from XML files, with Properties.loadFromXml(), inside JSF, without writing too much code? I know there are alternative ways to do so (writing my own loader, escaping the characters...), but I'd really love to find a simple solution, and I don't see it in all the forums I checked. Thanks in advance for any help

• When pressing Back/Menu button my app hangs

  - by Pentium10

  I am having a really annoying bug, which yet I don't know how to trace it. I have an activity with 3 tabs, each populated by adapters build by asynctasks. They are displaying well, navigation is fine. I've extended TabActivity. But whenever I hit the Back/Menu/Search button it halts, then after a while the OS displays me this warning: Sorry Activity Contacts (in application MyApp) is not responding. Force close or Wait. How can I trace this problem on the phone?

• C pointer initialization and dereferencing, what's wrong here?

  - by randombits

  This should be super simple, but I'm not sure why the compiler is complaining here. #include <stdio.h> #include <stdlib.h> int main(int argc, char *argv[]) { int *n = 5; printf ("n: %d", *n); exit(0); } Getting the following complaints: foo.c: In function ‘main’: foo.c:6: warning: initialization makes pointer from integer without a cast I just want to print the value that the pointer n references. I'm dereferencing it in the printf() statement and I get a segmentation fault. Compiling this with gcc -o foo foo.c.

• What workflow should I use for JavaScript editing?

  - by Patrick

  Warning: I have very little JavsScript experience. In my past programming experience, I usually have a standalone interpreter/compiler, a text editor and a command line to compile/run my software or my tests (I love test driven development). I really like it this way, since I have the feeling of being in complete control over the tools. However, editing JavaScript I need to put statements in a text file , open my web browser and click on reload. I don't feel comfortable with it, as I cannot really see what is going on (besides some alert boxes). Can you suggest me (I'm on a Mac) another workflow? Perhaps with a debugger? Is there a standalone JavaScript interpreter?

• Block upload of executable images (PHP)

  - by James Simpson

  It has come to my attention that a user has been trying to create an exploit through avatar image uploads. This was discovered when a user reported to me that they were getting a notice from their Norton Anti-virus saying "HTTP Suspicious Executable Image Download." This warning was referencing the user's avatar image. I don't think they had actually achieved anything in the way of stealing information or anything like that, but I assume it could be possible if the hole is left open long enough. I use PHP to upload the image files, and I check if the file being uploaded is a png, jpg, or gif.

• svn stat says folder uncontrolled, but won't let me svn add it!

  - by user246114

  Hi, Running into a weird problem with svm. I do svn stat in my controlled directory, lists something like: ? myproject/foo ? myproject/zoo so I do: svn add myproject/zoo and then I get this message back: svn: warning: 'myproject/zoo' is already under version control I don't get it, why is it showing it as uncontrolled then? I tried running svn cleanup, svn update, nothing though. I am also looking at my svn project in tracker, and I don't see the /zoo folder as present. What can I do to convince svn it's not really added? Thanks

• GAE JCache NumberFormatException, will I need to write Java to avoid?

  - by Jasper

  This code below produces a NumberFormatException in this line: val cache = cf.createCache(Collections.emptyMap()) Do you see any errors? Will I need to write a Java version to avoid this, or is there a Scala way? ... import java.util.Collections import net.sf.jsr107cache._ object QueryGenerator extends ServerResource { private val log = Logger.getLogger(classOf[QueryGenerator].getName) } class QueryGenerator extends ServerResource { def getCounter(cache:Cache):long = { if (cache.containsKey("counter")) { cache.get("counter").asInstanceOf[long] } else { 0l } } @Get("html") def getHtml(): Representation = { val cf = CacheManager.getInstance().getCacheFactory() val cache = cf.createCache(Collections.emptyMap()) val counter = getCounter(cache) cache.put("counter", counter + 1) val q = QueueFactory.getQueue("query-generator") q.add(TaskOptions.Builder.url("/tasks/query-generator").method(Method.GET).countdownMillis(1000L)) QueryGenerator.log.warning(counter.toString) new StringRepresentation("QueryGenerator started!", MediaType.TEXT_HTML) } } Thanks!

• Why do I have to give an identifier?

  - by Knowing me knowing you

  In code: try { System.out.print(fromClient.readLine()); } catch(IOException )//LINE 1 { System.err.println("Error while trying to read from Client"); } In code line marked as LINE 1 compiler forces me to give an identifier even though I'm not using it. Why this unnatural constrain? And then if I type an identifier I'm getting warning that identifier isn't used. It just doesn't make sense to me, forcing a programmer to do something unnecesarry and surplus. And after me someone will revise this code and will be wondering if I didn't use this variable on purpouse or I just forgot. So in order to avoid that I have to write additional comment explaining why I do not use variable which is unnecessary in my code. Thanks

• does a git repository have its own local value for core.autocrlf that overrides the global one?

  - by Warren P

  As per this question, I understand that core.autocrlf=true in git will cause CRLF to LF translations. However when I type : git config core.autocrlf I see: false However, when I stage modified files that are already in the repo, I still get these warnings: Warning: CRLF will be replaced by LF in File1.X. The file will have its original line endings in your working directory. My guess is that the repo copy of the file is already set to "autocrlf=true". Questions: A. How do I query whether a file or git repo is already forcing AutoCrlf? B. How do I turn it autocrlf off?

• a newbie gcc compiler and c language question

  - by dydx

  Hi, when I'm trying to compile my c program it gives me this error warning: integer constant is too large for 'long' type which refers to these lines int barcode, a, b, c; scanf("%d", &barcode); a = barcode / 1000000000000; b = barcode / 100000000000 % 10; c = barcode / 10000000000 % 10; and the rest is fine. I know I'm not supposed to use int for such a large number, any suggestions on what I should use? if I replace int with double what should the '%d' part be replaced with then?

• How do I do a has_many through association on a has_many through association in rails?

  - by Angela

  Warning: I may have the wrong 'problem statement' but here it goes: A Campaign has many Contacts. A Campaign has many Emails. Therefore, a Contact has many Emails through a Campaign. And an Email can have many Contacts through a Campaign. Each Contact-Email pair has its own unique Status (status1, status2, etc). Each Status (for a Contact-Email pair) will have its own User. I do not know how to model Status, or User. Currently the immediate challenge is Status. (see diagram below)

  - by Red Hyena

  I have an enum Fruit defined as: object Fruit extends Enumeration { val Apple, Banana, Cherry = Value } Now printing values of this enum, on Scala 2.7.x gives: scala> Fruit foreach println line1$object$$iw$$iw$Fruit(0) line1$object$$iw$$iw$Fruit(1) line1$object$$iw$$iw$Fruit(2) However the same operation on Scala 2.8 gives: scala> Fruit foreach println warning: there were deprecation warnings; re-run with -deprecation for details Apple Banana Cherry My question is: How is the method toString in Enumeration in Scala 2.8 is implemented? I tried looking into the source of Enumeration but couldn't understand anything.

• php - How do I get rid of this strange "empty delimiter" message

  - by Steven

  I have some code that uses the stristr function to extract data I need. It works, in that it gives me the results I'm looking for.

Can anyone suggest how i could amend this code to get rid of the message? Thanks in advance $data = stristr("$text", "$key"); $result = string_limit_words($data,2); print "$result<BR>";

• No exit option if something is running

  - by max

  How can I catch something going on if the user chooses the exit option from a menu? I mean I'd like to be able to manage the event of a user who is going to close the application but some activity is being performed so he/she shouldn't be able to exit. Here's the code I wrote. In a nutshell : recording is being performed -- user clicks exit -- WARNING "Process is running you can't do it"(The process goes on) nothing is running -- user clicks exit -- application closes Is it possible to solve the problem by just adding a few lines of code without having to rewrite the entire program? thanks very much in advance. MAX exitAction = new AbstractAction("Exit") { public void actionPerformed(ActionEvent e) { System.exit(0); } }; exitAction.putValue(Action.NAME, "Exit"); // description exitAction.putValue(Action.SHORT_DESCRIPTION, "Exit application");

• CodeMirror Dynamic Syntax Validation

  - by rawr

  Been trying to decide between using CodeMirror or Ace editor. I've been leaning towards CodeMirror, however there's one feature of Ace that I really like and that is how it does syntax validation. So as I'm typing there can appear a warning or error icon in the left gutter area beside the line number, and when I hover over it it gives me a little description. Is there any way to get this functionality in CodeMirror? Specifically, I'm using the css mode for CodeMirror. It'd also be nice to be able to add in my own custom validation. Thanks.

• Mysterious different conversion to string[] of seemingly same input data

  - by Roman Kuzmin

  During investigation of some problem I found that the reason was unexpected different conversion to string[] of seemingly same input data. Namely, in the code below two commands both return the same two items File1.txt and File2.txt. But conversion to string[] gives different results, see the comments. Any ideas why is it? This might be a bug. If anybody also thinks so, I’ll submit it. But it would nice to understand what’s going on and avoid traps like that. # *** WARNING # *** Make sure you do not have anything in C:\TEMP\Test # *** The code creates C:\TEMP\Test with File1.txt, File2.txt # Make C:\TEMP\Test and two test files $null = mkdir C:\TEMP\Test -Force 1 | Set-Content C:\TEMP\Test\File1.txt 1 | Set-Content C:\TEMP\Test\File2.txt # This gets just file names [string[]](Get-ChildItem C:\TEMP\Test) # This gets full file paths [string[]](Get-ChildItem C:\TEMP\Test -Include *) # Output: # File1.txt # File2.txt # C:\TEMP\Test\File1.txt # C:\TEMP\Test\File2.txt

• Logging to screen and to a file

  - by robUK

  What design pattern might apply to logging? What is normally used in this type of situation? Any good tutorials? I am writing a client-server application using C89 and gcc 4.4.4. I now need to implement some logging feature that will display log messages on the screen as well as log to a file. However, I don't want to display all log messages (warning, error, critical, unrecoverable, debug, etc). Maybe I can set so that it will display just errors and nothing else. For example, the user might not be interested in the debug messages on the screen output.

• How use AppEngine's Datastore Admin: Copy to Another App Feature

  - by Nick Siderakis

  I recently enabled AppEngine's Datastore Admin. I do not understand the instructions on how to copy my data to another app. Note: The target application must enable remote_api and must include this application’s ID in its HTTP_X_APPENGINE_INBOUND_APPID list. WARNING This application’s data is writable. We can only guarantee a consistent copy when the data being copied is read-only. Note: Blobs (binary data) will not be copied. To enable the remote_api I included the following in the app.yaml: builtins: - remote_api: on I have no idea what HTTP_X_APPENGINE_INBOUND_APPID is, and a Google search yields no results....any ideas?

• Handle CSliderCtl messages placed on a CDialogBar

  - by user173438

  VS2008, 32 Bit Win XP In a class derived from CFrameWnd, I have an object of CDialogBar that needs to have certain controls on it. Among these controls would be 2 sliders, whose event handling is to be done in CFrameWnd derived class. How shall I go about this? class CFrameWndCustom : public CFrameWnd { CDialogBar m_wndDialogBar; // the CDialogBar object. } In CFrameWnd derived class's OnCreateClient, I have created the DialogBar using the above object like: //Create the DialogBar if (!m_wndDialogBar.Create(this, IDD_DIALOGBAR_CONTROL, CBRS_BOTTOM, IDD_DIALOGBAR_CONTROL)) { TRACE("Warning: Couldn't create DialogBar Control!\n"); return FALSE; } Here, IDD_DIALOGBAR_CONTROL is a dialog resource with Style as Child. After this, I drag-dropped a CSliderCtrl on the IDD_DIALOGBAR_CONTROL in Resource View. Now, how/where should I handle the CSliderCtrl's events? There would be 2 such slider controls. I finally need the values of the sliders in CFrameWndCustom class. best regards, Divya
