• 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?

• R scatterplot overplotting color

  - by rgeekay

  So far I have this: qplot(df[[1]], as.numeric(rownames(df)), group=df[[2]], color=df[[2]], ylab="") I want to use different colors for the points in the 2 groups - perhaps a lighter shade for the what's in black now and a darker - say, red for what's in blue. Also, I want to use hexbin kind of thing for group=0 but not for group=1. I'm not able to get the syntax to get this working. In the current plot 0 is in black and 1 is in blue. Added: I worked on it some more, and by using factor and scale_colour_manual, I got the grey color for 0 and red for 1: > palette1 [1] "grey" "red" "blue" "violet" "black" fy=factor(y, labels=c('grey', 'red')) qplot(x, seq(1:length(x)),col=fy, ylab="") + geom_point() + scale_colour_manual(values=palette1) Pending questions are: How to first plot all the grey and then red on top (some of the red is now hidden because the grey is plotted over). How to apply the hexbin logic for group0 i.e. the grey points only and not for the red.

• Rails passenger production cache definition

  - by mark

  Hi I'm having a bit of a problem with storing data in rails cache under production. What I currently have is this, though I have been trying to work this out for hours already: #production.rb config.cache_store = :mem_cache_store if defined?(PhusionPassenger) PhusionPassenger.on_event(:starting_worker_process) do |forked| if forked Rails.cache.instance_variable_get(:@data).reset end end end I am using a cron job to (try to) save remote data to the cache for display. It is logged as being written to the cache but reportedly null. If anyone could point me toward a decent current tutorial on the subject or offer guidance I'd be extremely grateful. This is really, really frustrating me. :(

• Win32_PageFileUsage WMI call returning 0 for CurrentUsage

  - by Ryan Duffield

  I am querying for the current page file usage on Windows-based systems. This is meant to run on the .NET Framework, version 2.0 SP1 and has been tested (and works!) on Windows Vista, Windows 7, Windows Server 2003 R2 and Windows Server 2008. On Windows Server 2003 SP2 (original release, not R2) it appears to return 0: using (var query = new ManagementObjectSearcher("SELECT CurrentUsage FROM Win32_PageFileUsage")) { foreach (ManagementBaseObject obj in query.Get()) { uint used = (uint)obj.GetPropertyValue("CurrentUsage"); return used; } } This is simply returning the results from the first row returned for the WMI call. Even when a page file is being used, it returns 0. What causes the result to be 0 when it should be returning a larger value? It may be something specific to the machine in question, and could have nothing to do with the operating system version. I've also tried this with and without elevated privileges with the same results.

• iPhone framework paths?

  - by user158103

  I recently moved my projects to a new mac, along with a newer version of Xcode. When i opened my project i noticed that some files were red. So i remapped them by setting the path (by project path) and then providing the proper path location. Now my problem is that the frameworks that i have are red, and i cant find their location! I did set the framework paths to be "relative to current SDK" however. Can anybody help me get my frameworks mapped correctly? The frameworks im using are: - QuartzCore.framework - libsqlite3.0.dylib - UIKit.framework - Foundation.frameowrk - CoreGraphics.framework The XCode version is 3.1.4 (the only one installed). The iPhone app was originally created using a prior version of Xcode (i dont remember which version).

• Is this the correct way to reloadData on a UITableView?

  - by Sheehan Alam

  I am trying to append objects to my data source and then reload the table. Is this the correct way of approaching it? self.items is my datasource //Copy current items self.itemsCopy = [self.items mutableCopy];//[[NSMutableArray alloc] initWithArray:self.items copyItems:NO]; NSLog(@"Copy Size before append: %d",[itemsCopy count]); //Get new items int lastMsgID = [self getLastMessageID]; [self.coreData getMoreMessages:self.title lastID:lastMsgID]; //This will update self.items with 30 objects //Append new items [itemsCopy addObjectsFromArray:self.items]; //Empty items and copy itemsCopy [self.items removeAllObjects]; self.items = [self.itemsCopy mutableCopy]; NSLog(@"Actual Size after append: %d",[self.items count]); //Reload data [tableView reloadData];

• Document width calculated via Javascript is different in Firefox compared to other browsers

  - by Scarpelius

  I have a problem with retrieving the current page document width from Mozilla Firefox. While the rest of the browsers report the correct width of the document, Firefox reports a smaller one (example: at screen resolution of 1920x1080 IE, Chrome and Safari reports 1920 while Firefox reports 1903). I use document width in $(document).ready(function() { ... }); to reposition a div element. Funny this is that after using alert() inside this function, the element reposition correctly, though the document size is still smaller than other browsers.

• WPF UserControl event called only once?

  - by 742

  Hi Everyone, I need to bind two-way a property of a user control to a property of a containing user control. I also need to set a default value to the property from code in the child (cannot be done easily from XAML tags). If I call my code from the child constructor, the value is set in the parent but the change callback routine is not triggered (my understanding is that the parent doesn't yet exist at the time the child is created). My current workaround is to catch the Loaded event of the child and to call the code from the handler. Howver as Loaded is called more than once, I need to set a flag to set the property only the first time. I don't like this way, but I don't know if there is a single shot event that could be used, or if this can be done otherwise. Any feedback based on your experience?

• Determining if an offset is in between line numbers?

  - by Sophomore

  hi I need to determine if a given selection is in between a start line and an end line. I have an ILineRange and a given offset within the viewport of eclipse. (I need to know, if the selection (from a remote party) was made within the current viewport of the local user. Unfortunately, I cannot get an LineRange from the selection. I must rely on getOffset() and getLength()... Anyone has an idea? I think there is not a clean solution for this, as the offset (or the characters per line vary (new line lines or a big block of comment).

• Creating a library of classes in php - how to handle the library root location?

  - by jax

  I am about to create a collection of classes in php which are interrelated. Now I would like to include files using their absolute path, ie If I were in '/com/mysite/licences/Generator.class.php' I would like to include files like this: include '/com/mysite/lib/Utils.class.php' I don't want to include like this, I think it is confusing and ugly include '../licenses/Utils.class.php' This works ok, unless 'com' is not in the root of public_html. I assume I will need some sort of prefix to append to each file LIBRARY_ROOT that hold the location of 'com' in the current filesystem. So it might look like this include LIBRARY_ROOT.'com/mysite/lib/Utils.class.php' What is the best way to do this?

• Check for duplicate rows in 2 columns before update

  - by user3891378

  I have a table with 4 columns, and I need to check to see if a Column Pair exists before inserting a row into the database: INSERT INTO dbo.tblCallReport_Detail (fkCallReport, fkProductCategory, Discussion, Action) VALUES (?, ?, ?, ?) The pair in question is fkCallReport and fkProductCategory. For example if the row trying to be inserted has fkCallReport = 3 and fkProductCategory = 5, and the database already has both of those values together, it should display an error and ask if they would like to combine the Disuccsion and Action with the current record. Keep in mind I'm doing this in VBA Access 2010 and am still very new.

• Can you detect if and excel find and replace is active during worksheet_change()?

  - by John Griffiths

  Hi I've just crashed excel using amazon spreadsheet to update feed. When doing find and replace [replace all] with 2 cells selected after the first replacement the worksheet_change() function finished with the whole spreadsheet selected. This meant that the replacements took place outside of the original area. Unfortunatly the replcement text included the find text and each replacement re-selected the entire area excel ran until it ran out of space then crashed. Pressing control-break brings up the vba dialog STOP/CONTINUE/DEBUG. DEBUG is greyed out as amazon had protected the sheet. STOP would stop one run but would then continue to crash. CONTINUE would switch back to the current change and continue to crash. Is there any way to detect if a find&replace operation is in action whilst executing excel vba? Regards John

• Sharing memory between modules

  - by John Holecek

  Hi, I was wondering how to share some memory between different program modules - lets say, I have a main application (exe), and then some module (dll). They both link to the same static library. This static library will have some manager, that provides various services. What I would like to achieve, is to have this manager shared between all application modules, and to do this transparently during the library initialization. Between processes I could use shared memory, but I want this to be shared in the current process only. Could you think of some cross-platform way to do this? Possibly using boost libraries, if they provide some facilities to do this. Only solution I can think of right now, is to use shared library of the respective OS, that all other modules will link to at runtime, and have the manager saved there.

• create tree/XML structure from SQL query c#

  - by Tim Bassett

  Here is my current issue. I need to display a tree like structure displaying a recall roster. Our DBA created a stored procedure that returns [level],[name],[contact_info]. Example looks like: [1] [test name1] [contact info] [2] [sub to1] [contact info] [3] [sub to2] [contact info] [4] [sub to3] [contact info] [3] [sub to2] [contact info] [2] [sub to1] [contact info] etc... It's sorted in the order of the hierarchy I haven't really worked with XML much but is that the way to go in loading/presenting this data. Currently when I retrieving the data I'm returning it in a datatable. There may also be a need to export this data to Excel. Can anyone point me a good direction to go with this?

• How will web programming change as tablet PC's become more prevalent?

  - by MrGumbe

  In case you've been living under a rock, you may have noticed that Apple introduced a tablet PC. HP, Microsoft, Google, and others aren't too far behind. A lot of discussion and thought has been put into how a user would interact with traditional applications in a large touch screen environment, but how do you think this will affect the user interface of traditional web programming? What do you think will have to change with our current HTML controls? What new kinds of controls will be possible if we have touch-and-drag technology on our web pages?

• Remove successive 0th entries in args[] for a Java command line interface?

  - by Bill IV

  I recall seeing, somewhere, an example that stepped through String args[] by deleting the lowest numbered value(s) public static void main( String args[]) { while (args.length > 0 ) { // do something and obliterate elements from args[] } } Obviously, a variable tracking current position in args and compared to args.length will do it; or an ArrayList made from args[]'s contents, with argsAL.size(). Am I mis-remembering an ArrayList example? I know this is a borderline question, the likely answer is, "No, there isn't and there shouldn't be either!". Maybe I'm over-focused... Bill

• Most Efficient Way to Write to Fixed Width File (Ruby)

  - by Ruby Novice

  I'm currently working with extremely large fixed width files, sometimes well over a million lines. I have written a method that can write over the files based on a set of parameters, but I think there has to be a more efficient way to accomplish this. The current code I'm using is: def self.writefiles(file_name, positions, update_value) @file_name = file_name @positions = positions.to_i @update_value = update_value line_number = 0 @file_contents = File.open(@file_name, 'r').readlines while line_number < @file_contents.length @read_file_contents = @file_contents[line_number] @read_file_contents[@positions] = @update_value @file_contents[line_number] = @read_file_contents line_number += 1 end write_over_file = File.new(@file_name, 'w') line_number = 0 while line_number < @file_contents.length write_over_file.write @file_contents[line_number] line_number += 1 end write_over_file.close end For example, if position 25 in the file indicated that it is an original file the value would be set to "O" and if I wanted to replace that value I would use ClassName.writefiles(filename, 140, "X") to change this position on each line. Any help on making this method more efficient would be greatly appreciated! Thanks

• Issue using Python to solve the Coin problem [closed]

  - by challarao

  I'm attempting to solve a problem commonly known as the Coin problem, but using McNuggets. McNuggets come in boxes containing either 6, 9, or 20 nuggets. I want to write a python script that uses Diophantine equations to determine if a given number of McNuggets n can be exactly purchased in these groupings. For example: 26 McNuggets -- Possible: 1 6-pack, 0 9-packs, 1 20-pack 27 McNuggets -- Possible: 0 6-packs, 3 9-packs, 0 20-packs 28 McNuggets -- Not possible This is my current attempt at writing the solution in Python, but the output is incorrect and I'm not sure what's wrong. n=input("Enter the no.of McNuggets:") a,b,c=0,0,0 count=0 for a in range(n): if 6*a+9*b+20*c==n: count=count+1 break else: for b in range(n): if 6*a+9*b+20*c==n: count=count+1 break else: for c in range(n): if 6*a+9*b+20*c==n: count=count+1 break if count>0: print "It is possible to buy exactly",n,"packs of McNuggetss",a,b,c else: print "It is not possible to buy"

• IIS Multiple Domain Redirect

  - by bingles

  I currently have 2 domain names that I want to setup different websites for. I am currently looking at using some free hosting that works well for my current needs but doesn't give me any way to point "mydomain.com" to the actual site. Instead I have to give users a longer, harder to remember url. My proposed solution is to point my domains to my home ip and host a small ASP.NET app through IIS consisting of a redirect page that simply redirects to the appropriate site. Is there a way in ASP.NET to recognize which domain url was requested in order to know where to redirect the page to?

• Controling the visibility of a Bitmap in .NET

  - by ET

  Hi everyone, I am trying to create this simple application in c#: when the user double clicks on specific location in the form, a little circle will be drawn. By one click, if the current location is marked by a circle - the circle will be removed. I am trying to do this by simply register the MouseDoubleClick and MouseClick events, and to draw the circle from a .bmp file the following way: private void MouseDoubleClick (object sender, MouseEventArgs e) { Graphics g = this.CreateGraphics(); Bitmap myImage = (Bitmap)Bitmap.FromFile("Circle.bmp"); g.DrawImage(myImage, e.X, e.Y); } My problem is that I dont know how to make the circle unvisible when the user clicks its location: I know how to check if the selected location contains a circle (by managing a list of all the locations containig circles...), but I dont know how exactly to delete it. Another question: should I call the method this.CreateGraphics() everytime the user double-clicks a location, as I wrote in my code snippet, or should I call it once on initialization?

• any open source instant messenger?

  - by George2

  Hello everyone, I need to develop an instant messenger (like MSN Messagner, but only simple and basic function is fine), based on .Net (C#). I want to integrate the instant messenger with my current web site user. I want to know any open source (better C#) instant messenger to reference? BTW: some of the users are using internal IP address (behind a gateway or proxy, like 10.10.xxx.xxx) -- so in this scenario two users can not use point to point message transfer if both of them are behind a gateway? And I think I have to develop a server which acts as an intermediate party to transfer message between two users, correct? thanks in advance, George

• Add time to a Date object in javascript

  - by baiano

  I am trying to add time to a Date object in javascript but am not getting the results that I am expecting. I am trying to pull a timer off of the page and add it to the current time to get the unix timestamp value of when the timer will hit zero. The time on the page is displayed as " HH:MM:SS ". This is what I have: time=getTimerText.split(":"); seconds=(time[0]*3600+time[1]*60+time[2])*1000; to convert the time into milliseconds. fDate=new Date(); fDate.setTime(fDate.getTime()+seconds); add the milliseconds to the javascript timestamp alert(Math.round(fDate.getTime() / 1000)); convert the javascript timestamp to a unix timestamp Since the timer is counting down I should get the same result every time i run the script, but I don't. Can anyone see what I might be doing wrong here?

  i have a webpage with a lot of images (photo album). I am using lazyloading jquery plugin which is great to only load the images out of browser view when i scroll down. The one issue i have is that i want the loading icon to show up first on images loading IN the current view as well as some of them are big images and they show up with that bad browser "image not loaded yet" icon until they download. I don't see any property on this plugin to support this for both in view and for scrolling. does anyone know if this is possible?
