• How to normalize a database where different user groups have different kinds of profiles?

  - by Stephen

  My application database has a Groups table that separates users into logical roles and defines access levels (admin, owner, salesperson, customer service, etc.) Groups has many Users. The Users table contains login details such as username and password. Now I wish to add user profiles to my database. The trouble I'm having (probably due to my relative unfamiliarity with proper database normalization) is that different user groups have different kinds of profiles. Ergo, a salesperson's profile will include his commission percentage, whereas an admin or customer service would not need this value. So, would the proper method be to create a unique profile table for each group? (e.g. admin_profiles, or salesperson_profiles). or is there a better way that combines certain details in a generic profile, while some users have extended info. And if so, whats a good example of how to do this with the commission example given?

• How does Rails Plugin Storage work?

  - by Kevin

  Trying to figure out how to install rails plugins manually on windows so I have a few questions. What does the directory need to be named in vendor/plugins? Is it arbitrary or is it linked to something within the plugin config files or is that what you set in the environment.rb? Once I've copied the files to the correct directory, do I always need to run something inside like init.rb or is it good to go? What's the difference between 'require' and 'include'? Thanks!

• When we run an aspx page with client side scripting on IIS, we get an ActiveX control error?

  - by Ananya

  we have implemented the code for installing the messenger theme pack using the client side scripting in a web page. We are creating an object of the messenger using the classid .Using this object we call the installcontent() method and try to install the messenger theme pack hosted at following path: http://www.messengerexpressions.com/assets/worldCup/cabs/en-gb.cab Our code initially checks whether the messenger is installed on the user machine or not. Then it checks for the user login ,once the messenger is installed on the machine. And if the user is signed-in , the messenger theme pack is installed. The code currently when hosted on IIS checks the “Sign-In of the user” but when it tries to install the theme pack an error is thrown “An ActiveX control on this page is unsafe.Your current security settings prohibit running unsafe control on this page.As a result,this page may not be display as intended.” Please let us know if any setting is required on IIS for running this piece of codeor anything that we are missing out.

• Conditional themes in Visual Studio 2008

  - by Bala R

  Can I have different visual studio themes associated to different solutions? Here's my problem. I have two files with sames names that have almost identical contents from two different solutions, open simultaneously. Of course, I have the first solution open and the file from the second solution is opened from explorer and has no connection to the first solution what so ever. Is there any way I can distinguish the the file that belongs to the solution from the other file, just by a different tab color or something like that and without hovering over the tab to look up the path. Thanks

• Why does initWithFrame have the wrong frame value?

  - by greypoint

  I have a subclass of UIButton called INMenuCard and I am overriding the initWithFrame to include an activity indicator. The menuCard places correctly but any internal reference to "frame" give me "inf,inf,0,0" which means my activityIndicator subview is not placed correctly. What might I be missing? @implementation INMenuCard - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { CGRect innerFrame = CGRectInset(frame, 50.0f, 100.0f); activityIndicator = [[UIActivityIndicatorView alloc] initWithFrame:innerFrame]; activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhite; [self addSubview:activityIndicator]; } return self; } I am instantiating INMenuCard with (debugging shows the CGRect values are correct): CGRect cardFrame = CGRectMake(cardX, cardStartY, cardWidth, cardHeight); INMenuCard *menuCard = [[INMenuCard buttonWithType:UIButtonTypeCustom] initWithFrame:cardFrame]; [theView addSubView:menuCard];

• How can I create a boolean in the `if` statement within the for loop to check for existence of term prepended to filename %%f?

  - by user784637

  I have lyrics for about 60% of my song collection. The filename of the lyrics is the same as the file name of song with zzz_ prepended to the filename and .lrc as the extension. C:\Songs\album\song.mp3 C:\Songs\album\zzz_song.lrc I currently print the file names like so for /r "C:\Songs" %%f in (*.mp3 *.flac) do ( echo %%f ) How can I create a boolean in the if statement within the for loop as a check on the existence of lyrics files? I was thinking something like if exist zzz_%f echo zzz_%f.lrc but zzz_%f prepends zzz_ to the full file path (ex. zzz_C:\Songs\album\song.mp3) and .lrc is appended to the existing extension

• Drupal: How to render a form and table on same page

  - by Aaron

  Can someone help me render a form and table on the same page? I'm sure it's easy, but can't think of how to do it. Here's hook_menu: function ncbi_subsites_menu() { $items = array(); $items['admin/content/ncbi_subsites'] = array( 'title' => 'NCBI Subsites Module', 'description' => 'Informs Drupal about NCBI subsites as defined by the Content Inventory database', 'page callback' => 'ncbi_subsites_show_main_page', 'access arguments' => array( 'administer site configuration' ), 'type' => MENU_NORMAL_ITEM, ); return $items; } Here's the callback: function ncbi_subsites_show_main_page() { $subsites = ncbi_subsites_get_subsites_from_inventory(); // fnc returns associative array from inventory, defined in include return ncbi_subsites_make_table( $subsites ); } In the callback I call some helper functions that return a themed, paged table. What I want is a small form above the table. How would I that?

• overflow technique in stack

  - by metashockwave

  int main(void) { problem2(); } void doit2(void) { int overflowme[16]; //overflowme[37] =0; } void problem2(void) { int x = 42; doit2(); printf("x is %d\n", x); printf("the address of x is 0x%x\n", &x); } Would someone help me understand why overflowme[37] =0; from the doit2 function will overwrite the value of x? (please include Program Counter and Frame Pointer of the function doit2 in your explanation) Thank you! It works every time with Project properties-Configuration properties-C/C++ -Code Generation-Basic Runtime Checks set to "Default". so it's not an undefined behavior.

• SDL/Pygame failing to load PNG images with cx_Freeze

  - by jjackson

  I'm running Python 3.1 on Windows and I'm trying to distribute my Pygame script as an executable via cx_Freeze. Right now it seems to be working except that the exe build can't load any of my images: Cannot load image: C:\path\to\build\exe.win32-3.1\resources\image.png File is not a Windows BMP file Googling has revealed that this happens when the SDL imaging library doesn't get included correctly. However, SDL_image.dll and libpng12-0.dll are both put by cx_Freeze into my build directory, so it seems to me like everything should be fine. Why wouldn't it be able to load PNG images?

• How to launch a program as as a normal user from a UAC elevated installer

  - by KZ

  I'm writing an NSIS installer and the setup program elevates "as administrator" as needed on Windows 7 / vista. I need to run the installed program at the end of the install and don't want to launch it with the same privileges as the installer. The regular NSIS exec commands run the child process with the same permissions as the installer. There is a UAC plugin for NSIS, but the documentation on it isn't great and it seems v. new; I'd prefer not to use that plugin. Ideally, I'm looking for a small .exe I can include that'll launch the target program without UAC elevation. Does this exist? Any other suggestions? Thanks!

• Is there an easier way to reconcile a list of files and a directory with subfolders/files to find ch

  - by rwmnau

  I have a SQL Server table with a list of files (path + filename), and a folder with multiple layers and files in each layer. I'm looking for a way to reconcile the two without having to process the list twice. Currently, I'm doing this: For Each f as FileInfo In FileListFromDatabase If f.Exists is False, mark it as deleted in the database Next For Each f as FileInfo In RecursiveListOFFilesOnDisk If Not FileExistsInDatabase, then add it Next Is there a better way to do this? I'd like to avoid converting all the matching files (of which most will be) to FileInfo objects twice. Since I'm a T-SQL developer first, I'm picturing something like an OUTER JOIN of the two lists where they don't match. Something LINQ-ish?

• Bind Grid.Row / Grid.Column inside a DataTemplate

  - by Thorsten79

  Hope this is not a dupe. I would like to be able to do the following in XAML: <DataTemplate DataType="{x:Type NewGACCTestApp:ButtonVM}"> <Button Grid.Column="{Binding GridColumn}" Grid.Row="{Binding GridRow}" Content="{Binding Path=Info}" /> </DataTemplate> The Content binding works fine but Grid.Column and Grid.Row simply don't exist in the produced object. Not even when I set them to some value without binding (like in Grid.Column="1"). I've snooped the application and saw that inside my grid nobody ever sets Grid.Column and Grid.Row. Any ideas?

• pass parameter from controller to models condition

  - by Alex

  I'm trying to bind a param to a join via a named scope., but I'm getting an error. What is the correct way to do that? has_one :has_voted, :class_name => 'Vote', :conditions => ['ip = :userIp'] # named scopes scope :with_vote, lambda {|ip| { :include => [:has_voted], # like this ?? :conditions => [:has_voted => {:conditions => {:userIp => ip}} ] }} Idea.with_vote(request.ip).all I believe I need the condition definition in the model for it to appear in the ON clause of a JOIN, rather then in the WHERE one. Edit I'm trying to get the following query select Ideas.*, Votes.* from Ideas left outer join Votes on Votes.Idea_id = Idea.id AND Votes.ip = {request.ip}

• JSP Component Creation

  - by jboyd

  When creating JSP pages one thing that I'd often like is the ability to do something like this: <jsp:include page="fancystoryrenderer.jsp" value="${aStoryObjectInMyModel}/> ... fancystoryrenderer.jsp <div id="fancymainbody"> ... ${theStory.title} ... </div> The main important characteristics of this is that I can reuse the same component on the same JSP page in different places without having to copy paste the component and give the story variables different names, notice that the story is called "theStory" in the JSP and not "aStoryObjectInMyModel", the linkage between our model has been broken by the view, which is a good thing in this case How do you do this?

• Beginner questions regarding Python classes.

  - by Andy

  Hi. I am new to Python so please don't flame me if I ask something too noobish :) 1. Consider I have a class: class Test: def __init__(self, x, y): self.x = x self.y = y def wow(): print 5 * 5 Now I try to create an object of the class: x = Test(3, 4) This works as expected. However, when I try to call the method wow(), it returns an error, which is fixed by changing wow() to: def wow(self) Why do I need to include self and if I don't, what does the method mean?2. In the definition of __init__: def __init__(self, x, y): self.x = x self.y = y Why do I need to declare x and y, when I can do this: def __init__(self): self.x = x self.y = y I hope I am being clear... Thanks for your time.

• Cygwin diff won't exclude files if a directory is included in the pattern

  - by Dean Schulze

  I need to do a recursive diff using cygwin that needs do exclude all .xml files from certain directories, but not from other directories. According to the --help option I should be able to do this with with the --exclude=PAT option where PAT is a pattern describing the files I want to exclude from the diff. If I do this: diff -rw --exclude="classes/Services.xml" the diff does not ignore the Services.xml file in the classes directory. If I do this diff -rw --exclude="Services.xml" the diff does ignore the Services.xml file in all directories. I need to do something like this: diff -rw --exclude="*/generated/resources/client/*.xml" to ignore all .xml files in the directory */generated/resources/client/. Whenever I add path information to the --exclude pattern cygwin does not ignore the file(s) I've specified in the pattern. Is there some way to make cygwin diff recognize a pattern that identifies certain files in certain directories? It seems to not be able to handle any directory information at all.

• On Mac OS X, do you use the shipped python or your own?

  - by The MYYN

  On Tiger, I used a custom python installation to evaluate newer versions and I did not have any problems with that*. Now Snow Leopard is a little more up-to-date and by default ships with $ ls /System/Library/Frameworks/Python.framework/Versions/ 2.3 2.5 2.6 @Current What could be considered best practice? Using the python shipped with Mac OS X or a custom compiled version in, say $HOME. Are there any advantages/disadvantages using the one option over the other? My setup was fairly simple so far and looked like this: Custom compiled Python in $HOME and a $PATH that would look into $HOME/bin first, and subsequently would use my private Python version. Also $PYTHONPATH pointed to this local installation. This way, I did not need to sudo–install packages - virtualenv took care of the rest.

• Interface with inner implementation - good or bad

  - by dermoritz

  I am working on a project with many someInterface - someInterfaceImpl-pairs. Some days ago I got the idea (probably inspired by reading some objective c code) to include the default implementations as an inner class. Now some colleagues (all with much more java experience than me) saw this idea - feedback was between shocked and surprised ("this is working?"). I googled around a bit but didn't find much evidence of usefulness of this "pattern" (personal i like it): pdf-paper and a faq about code style What do you think - especially in those cases where an "default" implementation is tightly coupled to an interface. Update i just found this: Java Interface-Implementation Pair (see accepted answer)
