  • How to remove the title bar from a JFrame screenshot?

    - by Greg Harman
    I'm capturing a screenshot image of a JFrame via a "double buffering" approach, per below: public BufferedImage getScreenshot() { java.awt.Dimension dim = this.getPreferredSize(); BufferedImage image = new BufferedImage(dim.width, dim.height, BufferedImage.TYPE_INT_RGB); this.paint(image.getGraphics()); return image; } where this extends JFrame. The image that I get has a blank strip along the top where the title bar was. What's the most straightforward way to capture an image of the contents of the JFrame without the extra space allocated for the title bar?

  • Creating a Group of Groups in Django

    - by Greg
    I'm creating my own Group model; I'm not referring to the builtin Group model. I want each hroup to be a member of another group (it's parent), but there is the one "top" group that doesn't have a parent group. The admin interface won't let me create a group without entering a parent. I get the error personnel_group.parent_id may not be NULL. My Group model looks like this: class Group(models.Model): name = models.CharField(max_length=50) parent = models.ForeignKey('self', blank=True, null=True) order = models.IntegerField() icon = models.ImageField(upload_to='groups', blank=True, null=True) description = models.TextField(blank=True, null=True) How can I accomplish this? Thanks.

  • Join Where Rows Don't Exist or Where Criteria Matches...?

    - by Greg
    I'm trying to write a query to tell me which orders have valid promocodes. Promocodes are only valid between certain dates and optionally certain packages. I'm having trouble even explaining how this works (see psudo-ish code below) but basically if there are packages associated with a promocode then the order has to have one of those packages and be within a valid date range otherwise it just has to be in a valid date range. The whole "if PrmoPackage rows exist" thing is really throwing me off and I feel like I should be able to do this without a whole bunch of Unions. (I'm not even sure if that would make it easier at this point...) Anybody have any ideas for the query? if `OrderPromoCode` = `PromoCode` then if `OrderTimestamp` is between `PromoStartTimestamp` and `PromoEndTimestamp` then if `PromoCode` has packages associated with it //yes then if `PackageID` is one of the specified packages //yes code is valid //no invalid //no code is valid Order: OrderID* | OrderTimestamp | PackageID | OrderPromoCode 1 | 1/2/11 | 1 | ABC 2 | 1/3/11 | 2 | ABC 3 | 3/2/11 | 2 | DEF 4 | 4/2/11 | 3 | GHI Promo: PromoCode* | PromoStartTimestamp* | PromoEndTimestamp* ABC | 1/1/11 | 2/1/11 ABC | 3/1/11 | 4/1/11 DEF | 1/1/11 | 1/11/13 GHI | 1/1/11 | 1/11/13 PromoPackage: PromoCode* | PromoStartTimestamp* | PromoEndTimestamp* | PackageID* ABC | 1/1/11 | 2/1/11 | 1 ABC | 1/1/11 | 2/1/11 | 3 GHI | 1/1/11 | 1/11/13 | 1 Desired Result: OrderID | IsPromoCodeValid 1 | 1 2 | 0 3 | 1 4 | 0

  • How to get notification of workflow errors?

    - by Greg McGuffey
    I am having issues were a workflow is stalled because there is an issue with sending an email (send email activity). Typically, this is simply solved by resuming the workflow. I'm wondering if there any way to react to a workflow error, so the user knows they need to go in and resume the workflow. I'm also wondering about this relative to a workflow that is attempting to assign a task to a user who no longer exists in the CRM or one that has an invalid email address, which I'm assuming would cause errors in workflows as well. Any other suggestions related to this sort if issue would be welcome. Thanks!

  • How can I receive mouse events when a wrapped control has set capture?

    - by Greg
    My WndProc isn't seeing mouse-up notifications when I click with a modifier key (shift or control) pressed. I see them without the modifier key, and I see mouse-down notifications with the modifier keys. I'm trying to track user actions in a component I didn't write, so I'm using the Windows Forms NativeWindow wrapper (wrapping the component) to get Windows messages from the WndProc() method. I've tried tracking the notifications I do get, and I the only clue I see is WM_CAPTURECHANGED. I've tried calling SetCapture when I receive the WM_LBUTTONDOWN message, but it doesn't help. Without modifier (skipping paint, timer and NCHITTEST messages): WM_PARENTNOTIFY WM_MOUSEACTIVATE WM_MOUSEACTIVATE WM_SETCURSOR WM_LBUTTONDOWN WM_SETCURSOR WM_MOUSEMOVE WM_SETCURSOR WM_LBUTTONUP With modifier (skipping paint, timer and NCHITTEST messages): WM_KEYDOWN WM_PARENTNOTIFY WM_MOUSEACTIVATE WM_MOUSEACTIVATE WM_SETCURSOR WM_LBUTTONDOWN WM_SETCURSOR (repeats) WM_KEYDOWN (repeats) WM_KEYUP If I hold the mouse button down for a long time, I can usually get a WM_LBUTTONUP notification, but it should be possible to make it more responsive.. Edit: I've tried control-clicking outside of the component of interest and moving the cursor into it before releasing the mouse button, and then I do get a WM_LBUTTONUP notification, so it looks like the component is capturing the mouse on mouse-down. Is there any way to receive that notification when another window has captured the mouse? Thanks.

  • Windows Question: RunOnce/Second Boot Issues [closed]

    - by Greg
    Moved to Super User: Windows Question: RunOnce/Second Boot Issues I am attempting to create a Windows XP SP3 image that will run my application on Second Boot. Here is the intended workflow. 1) Run Image Prep Utility (I wrote) on windows to add my runonce entries and clean a few things up. 2) Reboot to ghost, make image file. 3) Package into my ISO and distribute. 4) System will be imaged by user. 5) On first boot, I have about 5 things that run, one of which includes a driver updater (I wrote) for my own specific devices. 6) One of the entries inside of HKCU/../runonce is a reg file, which adds another key to HKLM/../runonce. This is how second boot is acquired. 7) As a result of the driver updater, user is prompted to reboot. 8) My application is then launched from HKLM/../runonce on second boot. This workflow works perfectly, except for a select few legacy systems that contain devices that cause the add hardware wizard to pop up. When the add hardware wizard pops up is when I begin to see problems. It's important to note, that if I manually inspect the registry after the add hardware wizard pops up, it appears as I would expect, with all the first boot scripts having run, and it's sitting in a state I would correctly expect it to be in for a second boot scenario. The problem comes when I click next on the add hardware wizard, it seems to re-run the single entry I've added, and re-executes the runonce scripts. (only one script now as it's already executed and cleared out the initial entries). This causes my application to open as if it were a second boot, only when next is clicked on the add hardware wizard. If I click cancel, and reboot, then it also works as expected. I don't care as much about other solutions, because I could design a system that doesn't fully rely on Microsoft's registry. I simply can't find any information as to WHY this is happening. I believe this is some type of Microsoft issue that's presenting itself as a result of an overstretched image that's expected to support too many legacy platforms, but any help that can be provided would be appreciated. Thanks,

  • Setting up a "to-many" relationship value dependency for a transient Core Data attribute

    - by Greg Combs
    I've got a relatively complicated Core Data relationship structure and I'm trying to figure out how to set up value dependencies (or observations) across various to-many relationships. Let me start out with some basic info. I've got a classroom with students, assignments, and grades (students X assignments). For simplicity's sake, we don't really have to focus much on the assignments yet. StudentObj <--->> ScoreObj <<---> AssignmentObj Each ScoreObj has a to-one relation with the StudentObj and the AssignmentObj. ScoreObj has real attributes for the numerical grade, the turnInDate, and notes. AssignmentObj.scores is the set of Score objects for that assignment (N = all students). AssignmentObj has real attributes for name, dueDate, curveFunction, gradeWeight, and maxPoints. StudentObj.scores is the set of Score objects for that student (N = all assignments). StudentObj also has real attributes like name, studentID, email, etc. StudentObj has a transient (calculated, not stored) attribute called gradeTotal. This last item, gradeTotal, is the real pickle. it calculates the student's overall semester grade using the scores (ScoreObj) from all their assignments, their associated assignment gradeWeights, curves, and maxPoints, and various other things. This gradeTotal value is displayed in a table column, along with all the students and their individual assignment grades. Determining the value of gradeTotal is a relatively expensive operation, particularly with a large class, therefore I want to run it only when necessary. For simplicity's sake, I'm not storing that gradeTotal value in the core data model. I don't mind caching it somewhere, but I'm having a bitch of a time determining where and how to best update that cache. I need to run that calculation for each student whenever any value changes that affects their gradeTotal. If this were a simple to-one relationship, I know I could use something like keyPathsForValuesAffectingGradeTotal ... but it's more like a many-to-one-to-many relationship. Does anyone know of an elegant (and KVC correct) solution? I guess I could tear through all those score and assignment objects and tell them to register their students as observers. But this seems like a blunt force approach.

  • Logging to a file on Android

    - by Greg B
    Is there any way of retrieving log messages from an Android handset. I'm building an application which uses the GPS of my HTC Hero. I can run and debug the application from eclipse but this isn't a good use case of GPS, sat at my desk. When I fire the app up when I am walking around, I get an intermittent exception. Is there anyway I can output these exceptions to a text file on the SD card or output calls to Log.x("") to a text file so that I can see what the exception is. Thanks EDIT : Solution Here is the code I finally went with... Thread.currentThread().setUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() { @Override public void uncaughtException(Thread thread, Throwable ex) { PrintWriter pw; try { pw = new PrintWriter( new FileWriter(Environment.getExternalStorageDirectory()+"/rt.log", true)); ex.printStackTrace(pw); pw.flush(); pw.close(); } catch (IOException e) { e.printStackTrace(); } } }); I had to wrap the line pw = new PrintWriter(new FileWriter(Environment.getExternalStorageDirectory()+"/rt.log", true)); in a try/catch as Eclipse would not let me compile the app. It kept saying Unhandled exception type IOException 1 quick fix Sorround with try/catch So I did and it all works which is fine by me but it does make me wonder what Eclipse was on about...

    - by Greg K
    I added a new subdir within my git respository: git add feeds Then commited this and pushed it up to GitHub but it seems as though I've commited a symlink / shortcut but not the actual directory and files within. See here: http://github.com/G4EGK/RSS-Reader Any idea what 'feeds' is? I'd like to remove that and correctly add my files. I tried the following but git status said nothing had changed: git rm feeds git add feeds/\*.php To remove feeds do I run the following? git filter-branch --tree-filter 'rm -f feeds' HEAD

  • How to display combo box as textbox in WPF via a style template trigger?

    - by Greg R
    I would like to display a combobox drop down list as a textbox when it's set to be read only. For some reason I can't seem to bind the text of the selected item in the combo box to the textbox. This is my XAML: <Style x:Key="EditableDropDown" TargetType="ComboBox"> <Style.Triggers> <Trigger Property="IsReadOnly" Value="True"> <Setter Property="Background" Value="#FFFFFF" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ComboBox"> <TextBox Text="{TemplateBinding SelectedItem, Converter={StaticResource StringCaseConverter}}" BorderThickness="0" Background="Transparent" FontSize="{TemplateBinding FontSize}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" FontFamily="{TemplateBinding FontFamily}" Width="{TemplateBinding Width}" TextWrapping="Wrap"/> </ControlTemplate> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> <ComboBox IsReadOnly="{Binding ReadOnlyMode}" Style="{StaticResource EditableDropDown}" Margin="0 0 10 0"> <ComboBoxItem IsSelected="True">Test</ComboBoxItem> </ComboBox> When I do this, I get the following as the text: System.Windows.Controls.ComboBoxItem: Test I would really appreciate the help!

  • Meaning of tA tC and tP

    - by Greg Wiley
    If this is a duplicate I appoligize, but looking for two-letter strings is quite hard in any search. I'm looking for the meaning of tA tC and tP in the context of a mysql query. And in the spirit of "teaching a man how to fish" it would be great if you could point me in the right direction of where to find this info in the future. Edit: The Query $wpdb->get_row($wpdb->prepare("SELECT tA.* FROM ".AMYLITE_ADS." tA, ".AMYLITE_ADS_CAMPAIGNS." tC, ".AMYLITE_PACKAGES." tP WHERE tA.id=tC.ad_id AND tC.campaign_id=tP.campaign_id AND tP.zone_id=%d AND tP.date_end>CURDATE() GROUP BY tA.id ORDER BY RAND()", $zone->id));

  • JQuery cookie access has stopped working for GAE app

    - by Greg
    I have a google app engine app that has been running for some time, and some javascript code that checks for a login cookie has suddenly stopped working. As far as I can tell, NO code has changed. The relevant code uses the jquery cookies plugin (jquery.cookies.2.2.0.min.js)... // control the default screen depending // if someone is logged in if( $.cookies.get('dev_appserver_login') != null || $.cookies.get('ACSID') != null ) { alert("valid cookie!") $("#inventory-container").show(); } else { alert("INvalid cookie!") $("#welcome-container").show(); } The reason for the two checks is that in the GAE SDK, the cookies are named differently. The production system uses 'ACSID'. This if statement works in the SDK and now fails 100% of the time in production. I have verified that the cookie is, in fact, present when I inspect the page. Thoughts?

  • SSIS - Skip Missing Files

    - by Greg
    I have a SSIS 2008 package that calls about 10 other SSIS packages (legacy issues, don't ask). Each of those child packages loads a specific file into a table. But sometimes one or more of these input files will be missing. How can I let a child package fail (because a file is missing) but let the rest of the parent package keep on running? I've tried increasing the maximum error count on the parent package, the tasks in the parent package that call each child, and in the child package itself. None of that seemed to make any difference. I still get this error when I run it with a file missing: SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED. The Execution method succeeded, but the number of errors raised (2) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors. Edit: failpackageonfailure and faulparentonfailure are already all set to false everywhere.

  • What is the simplest, but solid, interface from WinForms to a SQL Server database?

    - by Greg
    Hi, If I wanted to have my data in SQL Server, but wanted to use a thick client WinForms application for users, what would be the best practice way to have calls occurring from WinForms to database? And how simple is this? I guess I'm trying to gauge to what extent there are issues with this approach and one needs to go for some (a) middle tier with web services, or (b) have to go asp.net or something. I really just have a simple app that needs a database and I'll only have a 10 - 30 clients on a LAN/WAN network that would be connecting in.

  • Domain model for an optional many-many relationship

    - by Greg
    Let's say I'm modeling phone numbers. I have one entity for PhoneNumber, and one for Person. There's a link table that expresses the link (if any) between the PhoneNumber and Person. The link table also has a field for DisplayOrder. When accessing my domain model, I have several Use Cases for viewing a Person. I can look at them without any PhoneNumber information. I can look at them for a specific PhoneNumber. I can look at them and all of their current (or past) PhoneNumbers. I'm trying to model Person, not only for the standard CRUD operations, but for the (un)assignment of PhoneNumbers to a Person. I'm having trouble expressing the relationship between the two, especially with respects to the DisplayOrder property. I can think of several solutions but I'm not sure of which (if any) would be best. A PhoneNumberPerson class that has a Person and PhoneNumber property (most closely resembles database design) A PhoneCarryingPerson class that inherits from Person and has a PhoneNumber property. A PhoneNumber and/or PhoneNumbers property on Person (and vis-a-versa, a Person property on PhoneNumber) What would be a good way to model this that makes sense from a domain model perspective? How do I avoid misplaced properties (DisplayOrder on Person) or conditionally populated properties?

  • how do use Ninject with class libraries I am developing?

    - by Greg
    Hi, If I am working on a class library how do I make use of Ninject here? Ie from the internal class library point of view and also from the client code? For example: should the class library have it's own IOC set up, or should it always assume the client code will supply? if no (ie it's upto the client to have the IOC in place) then where is the mapping data stored here'. Is this mapping of the class library's functionality to be places in the client? have a reusable library that is available, that uses interfaces with classes that use the getInstance concept to create concrete classes for you to use, then in this case would that make sense on the client side to use the IOC container to create instances of these classes? Or is that really applying a double layer of abstraction? Q2 Or in the cases where I'm building the reusable library myself and want the client to use an IOC container, then in my reusable library would I then dispense with any overhead of having factories or "getInstance" methods to instantiate the classes in the client? (i.e. as the IOC container would do this no?)

  • Rails: Different prices for different branches, association depending on two other models combined

    - by Greg Lemond
    I have three models: Service has_many :prices has_many :groups, through: prices Price belongs_to :service belongs_to :group Group has_many :prices I want to have an input field (Simple_Form) for every price. In views/services/_form.html.haml I do: simple_form_for @service do |f| simple_fields_for :groups do |g| simple_fields_for :prices do |p| p.input :price With this setup I only get input fields for already saved prices. How I can get a price field for every group? I tried to do it manually, but it got really nasty and didn't work either. Thanks for any ideas!

  • CSS Only Selecting Certain Classes

    Hi I'm working with a Wordpress template. I have a separate template page for the blog section. On the other pages of the site I have class that works fine and looks like this .post header h2 { display:none; } On the blog page, I add this to the CSS and it works as it should #main .post header h2 { display:block; } However if I try that with other classes like #main .wrapper { background-color:#000000; } Nothing happens. I've tried adding !important, I've also tried writing like such body.page-id-15 #main .wrapper { background-color:#000000; } with no luck. Here is a link to the site. http://gregtregunno.ca/news

  • Best way to use PL/SQL Pacakge Cursors from Pro*C

    - by Greg Reynolds
    I have a cursor defined in PL/SQL, and I am wondering what the best way to use it from Pro*C is. Normally for a cursor defined in Pro*C you would do: EXEC SQL DECLARE curs CURSOR FOR SELECT 1 FROM DUAL; EXEC SQL OPEN curs; EXEC SQL FETCH curs INTO :foo; EXEC SQL CLOSE cusr; I was hoping that the same (or similar) syntax would work for a packaged cursor. For example, I have a package MyPack, with a declaration type MyType is record (X integer); cursor MyCurs(x in integer) return MyType; Now I have in my Pro*C code a rather unsatisfying piece of embedded PL/SQL that opens the cursor, does the fetching etc., as I couldn't get the first style of syntax to work. Using the example EXEC SQL EXECUTE DECLARE XTable is table of MyPack.MyType; BEGIN OPEN MyPack.MyCurs(:param); FETCH MyPack.MyCurs INTO XTable; CLOSE MyPack.MyCurs; END; END-EXEC; Does anyone know if there is a more "Pure" Pro*C approach?
